Safety Standards for Fall Protection in the Construction Industry

AGENCY: Occupational Safety and Health Administration, U.S. Department 
of Labor.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Occupational Safety and Health Administration (OSHA) 
hereby revises the construction industry safety standards which 
regulate fall protection systems and procedures. These systems and 
procedures are intended to prevent employees from falling off, onto or 
through working levels and to protect employees from falling objects.
    The final rule corrects problems which have arisen during 
enforcement of the existing standards. In this final rule, OSHA either 
maintains or increases the requirements for protection from those 
hazards, but does so using more performance-oriented criteria where 
possible, rather than specification-oriented language. The final rule 
also consolidates and simplifies many of the existing provisions. This 
rulemaking is another step in OSHA's plan to review its safety 
standards and to revise them as necessary to provide safer working 
conditions without imposing unnecessary burdens.
    In addition, the final rule makes one change to a provision in the 
Occupational Safety and Health Standards for General Industry. In 
particular, Sec. 1910.269--Electric Power Generation, Transmission and 
Distribution; Electrical Protective Equipment which contains a 
requirement in paragraph (f)(2) that personal fall arrest equipment 
meet the requirements of subpart E of Part 1926. That provision has 
been revised to require the equipment to meet the requirements of 
revised subpart M of Part 1926.

EFFECTIVE DATE: This final rule becomes effective February 6, 1995.

ADDRESSES: In compliance with 28 U.S.C. 2112(a), the Agency designates 
for receipt of petitions for review of the standard, the Associate 
Solicitor for Occupational Safety and Health, Office of the Solicitor, 
Room S-4004, U.S. Department of Labor, 200 Constitution Avenue NW., 
Washington, DC 20210.

I. Background

    Congress amended the Contract Work Hours Standards Act (40 U.S.C. 
327 et seq.) in 1969 by adding a new section 107 (40 U.S.C. 333) to 
provide employees in the construction industry with a safer work 
environment and to reduce the frequency and severity of construction 
accidents and injuries. The amendment, commonly known as the 
Construction Safety Act (CSA) [P.L. 91-54; August 9, 1969], 
significantly strengthened employee protection by requiring the 
promulgation of occupational safety and health standards for employees 
of the building trades and construction industry working on Federally-
financed or Federally-assisted construction projects. Accordingly, the 
Secretary of Labor issued Safety and Health Regulations for 
Construction in 29 CFR Part 1518 (36 FR 7340, April 17, 1971) pursuant 
to section 107 of the Contract Work Hours and Safety Standards Act.
    The Occupational Safety and Health Act (OSH Act) (84 Stat. 1590; 29 
U.S.C. 651 et seq.), was enacted by Congress in 1970 and authorized the 
Secretary of Labor to adopt established Federal standards issued under 
other statutes, including the Construction Safety Act, as occupational 
safety and health standards. Accordingly, the Secretary of Labor 
adopted those Construction Standards, which had been issued under the 
Construction Safety Act in 29 CFR Part 1518, as OSHA standards in 
accordance with section 6(a) of the OSH Act (36 FR 10466, May 29, 
1971). The Safety and Health Regulations for Construction were 
redesignated as Part 1926 later in 1971 (36 FR 25232, December 30, 
1971).
    OSHA adopted several regulations related to fall protection under 
section 6(a) of the OSH Act. In particular, the Agency adopted the 
standards which currently appear in subpart E, Personal Protective 
Equipment, (including Sec. 1926.104--Safety Belts, Lifelines, and 
Lanyards and Sec. 1926.105--Safety Nets) and in subpart M, Floor and 
Wall Openings and Stairways. Subpart M has been amended several times 
under section 6(b) of the OSH Act.
    As part of OSHA's continuing standards evaluation program, and in 
response to public comments, a complete review of subpart M was begun 
in 1977. Since then, the Advisory Committee on Construction Safety and 
Health (ACCSH) has reviewed draft revisions of subpart M a number of 
times and has made many suggestions regarding the draft regulatory 
language. The transcripts of the ACCSH meetings where draft revisions 
to subpart M were discussed are part of the public record (Exhibit 1). 
The ACCSH recommendations, and those of other interested parties, have 
been carefully analyzed in connection with the present rulemaking. Many 
of the changes in the revised standard reflect the suggestions of the 
ACCSH and other interested persons. Specific ACCSH recommendations are 
discussed in the appropriate sections of the Summary and Explanation, 
below. Committee discussions that either were inconclusive or did not 
produce a specific recommendation have also been considered, but are 
not discussed in this preamble.
    On November 25, 1986, OSHA proposed to revise virtually all of the 
fall protection provisions of the construction industry standards and 
to consolidate those requirements, except where specifically provided 
otherwise, in subpart M [51 FR 42718]. The proposal set a period, 
ending February 23, 1987, during which interested parties could submit 
written comments and request a hearing. The Agency twice granted 
commenters' requests for more time to submit comments and hearing 
requests. OSHA first extended the comment and hearing request period to 
June 1, 1987 [52 FR 5790, February 26, 1987] and then extended that 
period to August 14, 1987 [52 FR 20616, June 2, 1987]. The Agency 
received 162 comments on the proposal and several requests for a 
hearing.
    On January 26, 1988, OSHA announced that it would convene an 
informal public hearing beginning on March 22, 1988, to elicit 
additional information on specific issues related to fall protection, 
scaffolds and stairways and ladders [53 FR 2048]. The hearing notice 
also reopened the comment period regarding proposed subpart M until 
March 8, 1988, for the limited purpose of obtaining additional 
information on appropriate fall protection coverage for employees 
engaged in steel erection activities. The Agency noted that the 
information obtained would be used in development of a separate 
proposed rule covering steel erection. OSHA received 22 comments in 
response to the limited reopening of the comment period.
    The informal public hearings were conducted on March 22-23, 1988, 
with Administrative Law Judge Joel Williams presiding. At the close of 
the hearings, Judge Williams set a period, ending May 9, 1988, for 
hearing participants to submit additional comments and information. 
OSHA received 15 submissions, including testimony and documentary 
evidence, at the hearing. On August 11, 1989, Judge Williams certified 
the rulemaking record, including the hearing transcript and all written 
submissions to the docket, thereby closing the record for this 
proceeding.
    On August 5, 1992, OSHA reopened the rulemaking record (57 FR 
34656) to consider new information submitted by the Precast/Prestressed 
Concrete Institute (PCI) regarding the fall protection needs of 
employees engaged in precast concrete construction. The PCI submissions 
(Exs. 25-4 and 25-6) described some characteristic precast concrete 
construction situations and alternative measures PCI believed employers 
could take to provide fall protection for their employees in those 
situations. The Agency solicited input on whether OSHA should allow 
precast concrete construction employers to protect employees from fall 
hazards by means other than guardrail systems, personal fall arrest 
systems or safety net systems. The Agency also sought comments 
regarding what criteria OSHA should set to determine the 
appropriateness of using alternative measures and to determine if the 
alternative measures are effectively minimizing fall hazards. The 
comment period, which ended November 3, 1992, elicited 14 comments.
    On March 29, 1993, the Agency again reopened the rulemaking record 
(58 FR 16515) to provide additional time for the precast concrete 
construction industry to comment on the issues raised in the August 5, 
1992, notice. The March 29 notice also discussed the fall protection 
needs of employees involved in residential construction, focusing on 
the feasibility of protecting employees erecting roof trusses and 
exterior wall panels with guardrails, personal fall arrest systems or 
safety net systems. OSHA requested information regarding alternative 
measures, or safe work practices, residential construction employers 
can use to minimize fall hazards. The limited comment period, which 
ended on May 28, 1993, elicited 28 comments.
    A wide range of employees, businesses, trade associations, state 
governments, and other interested parties contributed to the 
development of this record. The Agency appreciates these efforts to 
help OSHA develop a rulemaking record that provides a sound basis for 
the promulgation of this final rule.
    The Agency believes that, while the means of providing fall 
protection are continually improving, there may be circumstances where 
employers can demonstrate that compliance with certain fall protection 
requirements would be infeasible; i.e., it would be impossible to 
accomplish the work using conventional fall protection systems or it is 
technologically impossible to use conventional fall protection systems, 
or that those systems would create a greater hazard to employees. OSHA 
has determined that revised subpart M is needed to address those 
circumstances, encourage greater compliance by employers and employees, 
and maximize employee protection from fall hazards. OSHA believes that 
the clarified and revised language of the final rule will help 
employers to understand and implement the requirements of subpart M, 
resulting in improved employee protection. In addition, much of the 
final rule has been written in more performance-oriented language. This 
will make it easier for employers to provide the necessary protection 
for their employees, since they will be able to select fall protection 
measures which are compatible with the type of work being performed.
    This project has been coordinated with other ongoing projects for 
the revision of related general industry standards in 29 CFR Part 1910, 
subpart D--Walking/Working Surfaces, [proposed rule published at 55 FR 
13360, April 10, 1990] and 29 CFR Part 1910 subpart I--Personal 
Protective Equipment (Fall Protection Systems), [proposed rule 
published at 55 FR 13423, April 10, 1990] and with the proposed 
rulemaking for the Shipyard Industry in 29 CFR 1915 subpart M--Fall 
Protection [proposed rule published at 53 FR 48168, November 29, 1988]. 
Where appropriate, the 1910, 1915, and 1926 requirements will use the 
same language to address similar hazards so employers will have clear 
and consistent direction as to what is necessary to protect employees 
from fall hazards.
    In developing this final rule, OSHA has focused on requiring 
employers to provide construction employees with a positive method of 
protection against fall hazards wherever possible. At the same time, 
the Agency has taken steps to allow alternatives to traditional, 
conventional fall protection methods in situations where conventional 
methods can be shown to be inappropriate or unreasonable. Some of the 
alternative methods prescribed in revised subpart M represent 
innovations which are necessary to deal with unique workplace 
conditions. The record of this rulemaking indicates that these methods 
have not been used long enough or widely enough to enable the Agency to 
determine just how effective they will be throughout the construction 
industry.
    In this regard, OSHA intends to monitor the effectiveness of these 
provisions carefully for the next several years, to make sure that they 
are providing the necessary protection for construction workers. The 
Agency will carefully review and examine its enforcement data, together 
with any investigative reports and other information on accidents which 
involve fall hazards. In addition, OSHA intends to work closely with 
NIOSH in performing such data collection and analysis. Should the 
available data indicate that the alternative methods are not providing 
adequate fall protection to employees, the Agency will reevaluate the 
standards and determine what changes, if any, are warranted.

II. Hazards Involved

    Fall accidents resulting in injuries and fatalities continue to 
occur at construction sites despite the promulgation of the OSHA 
Construction Standards in 1971. OSHA's initial review of accident data 
indicated that compliance with existing OSHA standards would have, in 
general, prevented the mishaps. After a more complete review of 
information derived from enforcement experience and public comments, 
OSHA decided that certain existing provisions needed to be updated and 
clarified, in order to improve employee protection. In addition, OSHA 
decided to reorganize the existing fall protection requirements so that 
employers could more readily determine what requirements they must 
follow.
    Precise fall hazard accident data for the entire construction 
industry are not available. Falls are generally recorded by OSHA 
according to the nature of the injury and the surface involved, but the 
two categories have not been uniformly cross-referenced. However, based 
upon the data which have been compiled, OSHA estimates that there are 
at least 68,000 injuries due to falls from elevations covered under 
subpart M occur every year, and 95 fatalities (Regulatory Impact and 
Regulatory Flexibility Analysis, Section III).
    The U.S. Department of Labor, based on data from the Bureau of 
Labor Statistics, has listed falls as one of the leading causes of 
traumatic occupational death, accounting for 8% of all occupational 
fatalities in 1986. Data from NIOSH showed that from 1980-1985, falls 
represented about 10% of all traumatic occupational deaths for which a 
cause was identified, and that falls were shown to be one of the major 
causes of injuries to construction workers. A NIOSH analysis of death 
certificates from work related injuries over a 10-year period has made 
it clear that falls are the leading cause of work related injury death 
among construction workers (E. Lynn Jenkins, S.M. Kisner, D.E. 
Fosbroke, et al. Fatal Injuries to Workers in the United States, 1980-
89; A Decade of Surveillance--National Profile, DHHS, NIOSH, 93-108, 
August 1993).
    An OSHA study involving 99 fall-related fatalities (Ex. 3-3) 
suggests that virtually all of those deaths could have been prevented 
by the use of guardrails, body belts, body harnesses, safety nets, 
covers, or other means which would reduce employee exposure to the fall 
hazard.
    OSHA recognizes that such accidents are, generally, complex events, 
involving a combination of factors. Accordingly, the Agency notes that 
a number of human and equipment-related issues must be addressed to 
protect employees from fall hazards. Among those issues are the 
following:

    The need to know where protection is required;
    The selection of fall protection systems which are appropriate 
for given situations;
    The proper construction and installation of safety systems;
    The proper supervision of employees;
    The implementation of safe work procedures; and
    The proper training in the selection, use, and maintenance of 
fall protection systems.

    Each of these topics is covered in revised subpart M. The final 
rule requires employers to identify and evaluate fall hazards, and it 
includes specific training requirements that clarify the existing 
general training provisions of Sec. 1926.21 as they apply to fall 
protection. The final rule also makes it clear what an employer must do 
to provide fall protection for employees. Finally, the final rule 
relocates fall protection requirements from other subparts in the 
construction regulations, and places them in subpart M. For example, 
fall protection for workers on steep roofs was addressed by provisions 
in existing subpart L, but now will be addressed in revised subpart M.
    Based on its review of the incident data, OSHA has concluded that 
fall hazards pose a significant risk of death or serious injury for 
construction employees and that compliance with the requirements of 
revised subpart M is reasonably necessary to protect employees from 
those hazards. For a further discussion of accident rates and the 
significance of fall hazards in construction employment, see Section 
IV. Summary of the Regulatory Impact Analysis and Section V. Statutory 
Considerations.
    Certain proposed provisions have been reorganized in the final 
rule. The reorganized provisions are as follows:

III. Summary and Explanation of the Final Rule

    The following discussion explains how the final rule corresponds to 
or differs from the proposed and the existing standards, and how the 
comments and testimony presented on each provision influenced the 
drafting of the final rule. Except where otherwise indicated, proposed 
provisions which did not elicit comment have been promulgated as 
proposed, for the reasons stated in the preamble to the proposed rule.

Subpart M--Fall Protection

    OSHA has changed the title of subpart M from ``Floor and Wall 
Openings, and Stairways'' to ``Fall Protection.'' The revised title 
reflects both the relocation of the provisions for stairways to subpart 
X, which was published as a final rule on November 14, 1990 (55 FR 
47660), and the Agency's decision to consolidate most requirements for 
fall protection in construction in revised subpart M. OSHA has made 
subpart M the comprehensive reference for construction fall protection 
standards by revising and relocating the general requirements in 
existing Sec. 1926.104--Safety belts, lifelines, and lanyards; existing 
Sec. 1926.105--Safety nets; and the pertinent definitions in existing 
Sec. 1926.107 to subpart M.
    OSHA is also deleting Sec. 1926.651(l)(2), which requires fall 
protection at ``remotely located excavations,'' and 
Sec. 1926.701(f)(2), which requires fall protection for employees 
installing reinforcing steel more than 6 feet (1.8m) above adjacent 
working surfaces, because the pertinent hazards are covered by 
Secs. 1926.501(b)(7) and (b)(5), respectively. Another excavation 
provision, Sec. 1926.651(l)(1), is being revised to be consistent with 
Sec. 1926.501(b)(6) of the final rule. All three of the provisions 
noted above pertain to fall protection. In addition, the provision of 
existing Sec. 1926.105(a), has been relocated to Sec. 1926.753 of 
subpart R (steel erection) to maintain existing coverage pending 
rulemaking to revise the fall protection requirements for steel 
erection work. A more complete discussion of the revised and relocated 
provisions is provided later in this document.
Sec. 1926.500 Scope, Application, and definitions Applicable to This 
Subpart
    Paragraph (a) of Sec. 1926.500 states the scope and application of 
subpart M. Paragraph (a)(1) states that the fall protection 
requirements of subpart M apply to all construction workplaces, except 
where another subpart of part 1926 specifies what fall protection 
systems must be used and sets the criteria for those fall protection 
systems. OSHA notes there are some activities that will be classified 
as either general industry or construction depending on other 
activities occurring at the same time or same site. For example, when 
surface preparation work and sandblasting work are being performed in 
connection with painting activities or other construction activities, 
then these two activities are considered construction work and 
employers engaged in these activities must follow the requirements of 
subpart M as it pertains to fall hazards associated with surface 
preparation and sandblasting. On the other hand, when these activities 
are conducted as part of general maintenance work, the fall protection 
requirements of the general industry standards (part 1910) would apply.
    Paragraph (a)(1), which is essentially the same as proposed 
Sec. 1926.500(a)(1), also states that the provisions of subpart M do 
not apply when the employer establishes that employees are only 
inspecting, investigating, or assessing workplace conditions prior to 
the actual start of the work or after work has been completed. OSHA has 
set this exception because employees engaged in inspecting, 
investigating and assessing workplace conditions before the actual work 
begins or after work has been completed are exposed to fall hazards for 
very short durations, if at all, since they most likely would be able 
to accomplish their work without going near the danger zone. Also, the 
Agency's experience is that such individuals who are not continually or 
routinely exposed to fall hazards tend to be very focused on their 
footing, ever alert and aware of the hazards associated with falling. 
These practical considerations would make it unreasonable, the Agency 
believes, to require the installation of fall protection systems either 
prior to the start of construction work or after such work has been 
completed. Such requirements would impose an unreasonable burden on 
employers without demonstrable benefits.
    OSHA notes that the operations covered by paragraph (a)(1) are 
normally conducted in good weather, that the nature of such work 
normally exposes the employee to the fall hazard only for a short time, 
if at all, and that requiring the installation of fall protection 
systems under such circumstances would expose the employee who installs 
those systems to falling hazards for a longer time than the person 
performing an inspection or similar work. In addition, OSHA anticipates 
that employees who inspect, investigate or assess workplace conditions 
will be more aware of their proximity to an unprotected edge than, for 
example, a roofer who is moving backwards while operating a felt laying 
machine, or a plumber whose attention is on overhead pipe and not on 
the floor edge.
    Some commenters (Exs. 2-15, 2-31, and 2-56) expressed concern 
regarding the proposed exception. In particular, one commenter (Ex. 2-
31) said ``the exception . . . will create havoc for enforcement 
agencies.'' The commenter further stated that ``superintendents, 
foremen, and other company officials will never have to be protected 
during the entire job, because they will say that they are only 
inspecting.'' Another commenter (Ex. 2-15) suggested that OSHA grant 
only a conditional exception. It would then allow the exception only 
where exposures to falling are minimal at most or nonexistent. In 
addition, only experienced, responsible persons trained in the hazards 
associated with inspections, investigations, etc., would be allowed to 
work without fall protection. One commenter (Ex. 2-56) disagreed with 
the proposed exclusion, saying:

    These employees are exposed to unique hazards since their 
functions are to determine if protection systems are adequate, 
deteriorated, etc. To allow such employees to work unprotected will 
promote the not wearing or using such protection by others.

    Based on the comments received, OSHA recognizes that proposed 
Sec. 1926.500(a)(1) requires clarification. Therefore, OSHA has decided 
to reword the provision to make it clear that the exclusion only 
applies when the employer establishes that employees are inspecting, 
investigating, or assessing workplace conditions prior to the actual 
start of work or after the work has been completed. It was OSHA's 
intent when it proposed this provision that the exclusion would only 
apply at the two times stated above, not during the period when 
construction work is being performed. As explained in the preamble to 
the proposed rule, the exception would apply where an employee goes 
onto a roof in need of repair to inspect the roof and to estimate what 
work is needed. During such an inspection, guardrails, body belts, body 
harnesses, safety nets, or other safety systems would not be required. 
However, if inspections are made while construction operations are 
underway, all employees who are exposed to fall hazards while 
performing these inspections must be protected as required by subpart 
M. The intent of the provision is also to recognize that after all work 
has been completed, and workers have left the area, there may be a need 
for building inspectors, owners, etc. to inspect the work. OSHA 
recognizes that in these situations, all fall protection equipment, 
such as perimeter guardrail systems, may have been removed. OSHA is not 
requiring the installation of the systems for a second time for 
inspectors, because the Agency recognizes it would be unreasonably 
burdensome to require the reinstallation of fall protection equipment 
after all the work has been completed.
    Paragraph (a)(2), like the proposal, notes that some subparts 
within part 1926 aside from subpart M contain fall protection 
requirements. Those other provisions, however, are not comprehensive. 
Therefore, when an employee is exposed to a falling hazard, such as 
that of falling more than 6 feet to a lower level, which is not 
specifically addressed in another subpart, OSHA intends that the 
general provisions of subpart M apply. For example, while subpart N 
contains requirements for fall protection when certain cranes are used, 
it does not address other equipment or workplace conditions otherwise 
covered by subpart N which may also expose employees to a fall hazard. 
Also, paragraph (a)(3) provides that if another subpart requires the 
use of specified fall protection systems but does not set criteria 
which those systems must meet, the criteria set in subpart M apply. For 
example, subpart L--Scaffolds, requires that employers provide 
guardrails and safety belts (body belts) when employees are working on 
scaffolds. Subpart L sets criteria for the use of guardrail systems on 
scaffolds, but does not set criteria for the use of body belts. Under 
those circumstances, body belts used by employees working on scaffolds 
must satisfy the criteria in subpart M, while guardrails would be 
required to meet the criteria in subpart L.
    Aside from subpart L, the subparts in part 1926 that address the 
subject of fall protection are subparts N, R, S, V and X.
    A brief summary of the fall protection topics covered for each of 
the above-mentioned subparts is listed below.
     Subpart N--Cranes and Derricks. Requirements to have fall 
protection for employees working on certain cranes and derricks are 
contained in subpart N.
     Subpart R--Steel Erection. Requirements to have fall 
protection for employees engaged in the construction of skeleton steel 
buildings are contained in subpart R.
     Subpart S--Underground Construction, Caissons, Cofferdams, 
and Compressed Air. Requirements to have fall protection on specified 
pieces of equipment used in under-ground construction operations are 
contained in subpart S.
     Subpart V--Power Transmission and Distribution. 
Requirements to have fall protection for employees engaged in the 
construction of electric transmission and distribution lines and 
equipment are contained in subpart V.
     Subpart X--Stairways and Ladders. Requirements to have 
fall protection for employees working on stairways and fixed ladders 
are contained in subpart X. Subpart X already references the current 
fall protection criteria set out in subpart M, and that reference will 
now incorporate the revised criteria in Sec. 1926.502 of this final 
rule.
    OSHA notes that the proposed rule also identified subpart O as 
containing requirements for fall protection for employees on pile 
driving equipment. OSHA has not included this exclusion in the final 
rule because subpart O does not actually contain a requirement to have 
fall protection equipment; rather, it only contains a requirement that 
attachment points be provided to facilitate attachment of personal fall 
arrest equipment.
    OSHA received several comments related to proposed paragraph 
(a)(2). Two commenters (Exs. 2-19 and 2-56) indicated some confusion 
regarding the extent to which employees engaged in steel erection 
activities would be covered by the requirements of proposed subpart M. 
Based on the apparent confusion and the Agency's recognition that a 
complete revision of subpart R--Steel Erection, was needed, OSHA 
decided to defer consideration of changing current fall protection 
requirements as they apply to steel erection of buildings to the 
subpart R rulemaking. However, as noted in the hearing notice (53 FR 
2048) information gathered through the subpart M rulemaking on fall 
protection for steel erection will be used to help the Agency develop 
proposed revisions to subpart R. Therefore, pending completion of the 
subpart R rulemaking, OSHA will continue to apply the existing fall 
protection requirements of part 1926 to steel erection operations. To 
this end, as noted above, OSHA is relocating existing Sec. 1926.105(a) 
to subpart R as Sec. 1926.753. This provision will remain in subpart R 
until a final rule for revised subpart R becomes effective. In this 
way, OSHA ensures that employers engaged in steel erection activities 
currently covered by the existing, unrevised fall protection 
requirements remain covered until the rulemaking on subpart R is 
completed.
    Section 1926.500(b) lists and defines all major terms used in the 
final rule. Many of the proposed terms and definitions have been 
promulgated unchanged or with only editorial revisions. These terms 
include ``dangerous equipment,'' ``equivalent,'' ``failure,'' 
``guardrail system,'' ``hole,'' ``low-slope roofs,'' ``mechanical 
equipment,'' ``opening,'' ``overhand bricklaying and related work,'' 
``positioning device system,'' ``roof,'' ``safety monitoring system,'' 
``steep roof,'' ``work area.'' The proposed terms and definitions which 
did not elicit comment and which are being promulgated without change 
or with only editorial changes are not discussed below. However, all 
other terms and definitions, including any revisions, additions, and 
deletions, are discussed below.
    Also, OSHA notes that several commenters indicated that they had 
already provided comments on terms used in relation to personal fall 
arrest systems and positioning device systems covered by OSHA's 
proposed rule for powered platforms (Docket S-700A), and requested that 
OSHA consider their comments in regard to the proposed terms and fall 
protection requirements of subpart M. Those commenters included the 
Industrial Safety Equipment Association (ISEA), Research and Trading 
Corporation (RTC), and the ANSI Z359 Committee Chairman (testifying on 
behalf of the U.S. Technical Advisory Group, an advisory group 
representing Government and private interests on personal equipment for 
protection against falling, ISO/TC94/SC4 (USTAG) in the powered 
platform rulemaking) (Exs. 2-23, 2-36, 2-50, and 3-13).
    OSHA has considered those comments and has reviewed the powered 
platforms rulemaking record (final rule, Sec. 1910.66, published July 
28, 1989; 54 FR 31408), in general, for information relating to fall 
protection. Based on that review, OSHA has decided that those terms 
defined in the powered platforms rule which relate to personal fall 
arrest systems will also be defined in subpart M, where such terms are 
used in the final rule. Consequently, definitions for the following 
terms have been added to subpart M: ``anchorage,'' ``buckle,'' 
``connector,'' ``free fall,'' ``rope grab,'' ``self-retracting 
lifeline/lanyard,'' and ``snap-hook.'' These terms were used in the 
proposed rule and had the same meaning as provided in the definitions 
used in this final rule. OSHA believes this action will promote 
consistency throughout OSHA standards with regard to fall protection 
and OSHA intends to use the same terminology and definitions in its 
rules covering the same type of equipment. The newly defined terms and 
proposed terms that elicited comment are discussed below.
    ``Anchorage.'' This term is defined to be a secure point of 
attachment for lifelines, lanyards, or deceleration devices.
    ``Body belt/harness system.'' The term ``body belt/harness system'' 
has been changed to ``personal fall arrest system'' for the sake of 
uniformity with the general industry standard for powered platforms. 
The term ``personal fall arrest system'' is discussed in detail below.
    ``Body harness.'' Although there were no comments on the proposed 
definition of this term, OSHA has reworded the definition so that it is 
identical to the definition of ``body harness'' in the final rule on 
powered platforms.
    Again, the purpose of this rewording is to promote consistency in 
the OSHA regulations. The rewording does not alter the meaning of the 
term as proposed.
    ``Buckle.'' This term is defined to mean any device for holding the 
body belt or body harness closed around the employee's body. The ISEA 
(Ex. 2-23) suggested that a definition for the term buckle was needed. 
OSHA agrees and has defined the term in this final rule, using the 
language from the final rule on powered platforms. In the final rule on 
powered platforms, OSHA stated the following, which OSHA believes is 
also applicable to this rulemaking (See 54 FR 31446):

    One comment was received on the definition of ``buckle'' 
[citation omitted] which suggested that the term was superfluous and 
should be addressed in a separate national consensus standard for 
body support systems. OSHA disagrees since the term is used in the 
OSHA standard and there is not yet a national consensus standard for 
body support systems which includes this term.

    ``Built-up roofing.'' OSHA proposed to define the term ``built-up 
roofing'' to mean a weatherproofing cover, applied over roof decks, 
consisting of a liquid-applied system, a single-ply system, or a 
multiple-ply system. Liquid-applied systems generally consist of 
silicone rubber, plastics, or similar material applied by spray or 
roller equipment. Single-ply systems generally consist of a single 
layer of synthetic rubber, plastic or similar materials, and often, but 
not always, a layer of adhesive. Multiple-ply systems generally consist 
of layers of felt and bitumen. Any of the systems may be covered with a 
layer of mineral aggregate.
    OSHA has removed this term from the definition paragraph because 
the Agency has determined, as discussed below in relation to 
Sec. 1926.501(b)(10), that there is no need to provide for different 
fall protection requirements for low-slope roofs based on the type of 
work (e.g., built-up roofing) being performed.
    ``Connector.'' This term is used in the final rule in place of the 
term ``hardware'' which was used in the proposed rule. It is defined to 
mean a device which is used to couple (connect) parts of the personal 
fall arrest system or positioning device system together. It may be an 
independent component of the system, such as a carabiner, or it may be 
an integral component of part of the system (such as a buckle or dee-
ring sewn into a body belt or body harness, or a snap-hook spliced or 
sewn to a lanyard or self-retracting lanyard). The term and definition 
in the final rule are the same as those in the powered platforms final 
rule [54 FR 31470], in which OSHA stated the following, which OSHA 
believes is applicable to this rulemaking (See 54 FR 31446):

    OSHA is replacing the proposed term ``hardware'' with the term 
``connector.'' Two commenters stated that ``hardware'' was too broad 
and one suggested that the term ``connector'' be used instead 
[citations omitted]. OSHA agrees with these suggestions, notes that 
``connector'' connotes the specific function at issue, has deleted 
the term ``hardware,'' replaced it with the term ``connector'' and 
has expanded the definition.

    ``Controlled access zone'' (CAZ). This term is used to describe a 
work area designated and clearly marked in which certain types of work 
(such as overhand bricklaying work) may take place without the use of 
conventional fall protection systems--guardrail systems, personal fall 
arrest systems, or safety net systems--to protect the employees working 
in the zone. Access to the zone must be controlled to limit the number 
of workers exposed to fall hazards. OSHA observes that safety 
monitoring systems may be required where a CAZ is used as part of a 
fall protection plan (see Sec. 1926.502(k)). The proposed term 
``control zone'' was essentially identical.
    One commenter (Ex. 2-157) stated ``the definition of control zone 
in [proposed] Sec. 1926.502(g) does not appear to be applicable to 
scaffolds. OSHA acknowledges that a controlled access zone would not be 
used on a scaffold, although scaffolds might be used within a 
controlled access zone. Requirements to have fall protection on 
scaffolds both within and outside of controlled access zones are found 
in subpart L--Scaffolds.
    Another commenter, the Mason Contractors Association of America 
(Ex. 2-95), suggested that the term ``control zone system'' used in the 
proposal should be changed to ``controlled access zone'' (CAZ) to more 
effectively and correctly describe the function of a control zone. OSHA 
agrees with the commenter and has changed the term. There were no other 
substantive comments on the definition.
    OSHA notes that the use of a controlled access zone is permitted 
only in Overhand bricklaying and related work, (Sec. 1926.501(b)(9)) 
and as part of a Fall Protection Plan (see Sec. 1926.502(k) for Leading 
edge work (Sec. 1926.502(b)(2)(i)); Precast concrete work 
(Sec. 1926.501(b)(12)); or residential construction work 
(Sec. 1926.501(b)(13)).
    ``Deceleration device.'' This term describes a piece of equipment 
used to bring a falling employee to a stop without injury. The proposed 
definition of ``deceleration device'' has been revised to be consistent 
with the definition used in OSHA's final rule on powered platforms [54 
FR 31470]. There were several comments received on the proposed 
definition and in response to Issue #21. In this issue, OSHA discussed 
the use of the term ``deceleration device'' in the proposals for both 
the construction fall protection requirements of subpart M and the fall 
protection requirements for the general industry standard on powered 
platforms, subpart F. Bristol Steel and the NEA (Exs. 2-12 and 2-43) 
commented that the term is sufficiently descriptive. The ISEA, the Mine 
Safety Appliance Company (MSA), and the SSFI (Exs. 2-23, 2-35, and 2-
89) suggested rewording the definition because they viewed it as 
misleading and confusing. Other commenters, including the National 
Constructors Association and the BCMALU (Exs. 2-45 and 2-46), suggested 
replacing the term with ``shock absorber'' or ``fall arrester,'' 
respectively. RTC (Ex. 2-36) and the ANSI Z359 Committee/USTAG 
representative (Ex. 2-50) referred OSHA to their comments on the 
proposal for powered platforms. The following discussion from the final 
rule on powered platforms [54 FR 31446] covers those comments:

    Comments were received on the definition of ``deceleration 
device'' [citations omitted]. It was suggested that this term be 
eliminated and replaced with three terms, ``fall arrester,'' 
``energy absorber,'' and ``self-retracting lifeline/lanyard'' 
because the examples listed by OSHA in its proposed definition of 
deceleration device serve varying combinations of the function of 
these three suggested components. In particular, it was pointed out 
that a rope grab may or may not serve to dissipate a substantial 
amount of energy in and of itself. The distinction that the 
commenter was making was that some components of the system were 
``fall arresters'' (purpose to stop a fall), others were ``energy 
absorbers'' (purpose to brake a fall more comfortably), and others 
were ``self-retracting lifeline/lanyards'' (purpose to take slack 
out of the lifeline or lanyard to minimize free fall). OSHA notes, 
however, that it is difficult to clearly separate all components 
into these three suggested categories since fall arrest (stopping) 
and energy absorption (braking) are closely related. In addition, 
many self-retracting lifeline/lanyards serve all three functions 
very well (a condition which the commenter labels as a ``subsystem'' 
or ``hybrid component''). OSHA believes that the only practical way 
to accomplish what is suggested would be to have test methods and 
criteria for each of the three component functions. However, at this 
time, there are no national consensus standards or other accepted 
criteria for any of the three which OSHA could propose to adopt.
    In addition, OSHA's approach in the final standard is to address 
personal fall arrest equipment on a system basis. Therefore, OSHA 
does not have separate requirements for ``fall arrestors,'' ``energy 
absorbers'' and ``self-retracting lifeline/lanyards'' because it is 
the performance of the complete system, as assembled, which is 
regulated by the OSHA standard. OSHA's final standard does not 
preclude the voluntary standards writing bodies from developing 
design standards for all of the various components and is supportive 
of this undertaking * * *.
    OSHA has, however, used the commenters' suggestions to clarify 
the definition of ``deceleration device,'' as well as further 
clarify the test methods applicable to the various assembled systems 
*  *  *.

    After a careful review of the comments received and for the reasons 
above, OSHA has determined that the term ``deceleration device'' is 
appropriate, but the definition has been revised to clarify that 
deceleration devices serve to dissipate a substantial amount of the 
energy imposed on an employee during fall arrest or otherwise limit the 
energy imposed on an employee during fall arrest. The definition 
mentions several examples of mechanisms which accomplish this function.
    ``Deceleration distance.'' This term is used to describe the 
distance a falling employee travels (excluding lifeline elongation and 
free fall distance). Aside from some editorial revision, the definition 
in the final rule is identical to the proposed definition. The ISEA and 
the MSA (Exs. 2-23 and 2-35) commented that the proposed definition, 
just as the proposed definition in powered platforms, could cause 
confusion, such as the mistaken belief that deceleration distance was 
the total fall distance. OSHA agrees with the commenters and has 
reworded the definition of deceleration distance to remove the point of 
confusion. In particular, OSHA has eliminated the words ``excluding 
lifeline elongation between those two points'' that appeared in the 
subpart M proposed rule. The definition in the final rule is consistent 
with the definition in Sec. 1910.66, powered platforms. OSHA has also 
considered the comments which were provided to the powered platform 
rulemaking record (Ex. 3-13). OSHA's discussion of those comments in 
the final rule on powered platforms [54 FR 31447] is applicable here 
and appears below:

    Several comments were received on the proposed definition for 
``deceleration distance'' [citations omitted]. Concern was expressed 
by all commenters that it was only possible to evaluate the stopping 
distance for the device itself once it was activated. OSHA agrees 
with these comments and has revised the definition of deceleration 
distance to exclude lifeline elongation and any free fall distance 
which occurs before the device is activated. In addition, 
suggestions for clarification of the definition were accepted.

    ``Failure.'' This term describes load refusal, breakage, or 
separation of component parts where the ultimate strength has been 
exceeded. Four commenters (Exs. 2-16, 2-23, 2-45, and 2-56) expressed 
concern regarding the definition of the term ``failure.'' Two of these 
commenters, (Exs. 2-16 and 2-23), noted that the term ``failed'' as 
used in proposed paragraph (c) of the proposed non-mandatory Appendix 
C, was inconsistent with the proposed definition of ``failure.'' OSHA 
agrees, and has both deleted the term from the Appendix and reworded 
the Appendix to remove the potential for confusion. Additionally, a 
commenter (Ex. 2-56) asked, ``what is load Refusal?'' which is a phrase 
used as part of the definition of the term ``failure.'' OSHA uses the 
phrase in a situation where whatever is supposed to support the load is 
refusing to do so--it is not performing its intended purpose. Hence, it 
has failed its purpose and is not supporting the load.
    OSHA has determined that as clarified above, the proposed 
definition of ``failure'' is appropriate for the final rule.
    ``Force factor.'' The term force factor was defined in the proposed 
rule. The term has been deleted in the final rule because, as explained 
in the final rule on powered platforms [54 FR 31447], the comments and 
testimony suggested that the term ``force factor'' was confusing, even 
to systems experts. The Agency also noted that the term would not be 
needed if the factor was incorporated into the test methods. OSHA 
agreed with those commenters and deleted the term ``force factor'' from 
the final rule on powered platforms, while incorporating the concept in 
the test methods section. OSHA has taken the same action in this final 
rule.
    ``Free fall'' means the act of falling before the personal fall 
arrest system begins to apply force to arrest the fall. OSHA did not 
propose a definition for this term. The term and definition in the 
final rule are identical to the ones used in the final rule on powered 
platforms [54 FR 31470]. OSHA has determined that the inclusion of this 
definition is appropriate for purposes of clarity and to provide 
guidance consistent with that set in the powered platforms standard. 
OSHA believes that the following language which appeared in the final 
rule on powered platforms (54 FR 31447) is applicable to this 
rulemaking:

    One comment was received on the proposed definition of free fall 
[citation omitted] suggesting that the phrase ``personal fall arrest 
system'' should be used as well as the definition being further 
clarified to define when the free fall period ends. OSHA agrees with 
this suggestion and has revised the definition of free fall 
accordingly.

    ``Free fall distance.'' This term is used to describe the vertical 
distance an employee moves during a fall before a deceleration device 
is activated. Although there were no comments on the proposed 
definition, OSHA has reworded the definition to be consistent with the 
definition used in the final rule for powered platforms [54 FR 31447 
and 31470]. The rewording does not substantively alter the meaning of 
the term, as proposed.
    ``Hole.'' This term is used to describe a void or gap 2 inches (5.1 
cm) or more in its least dimension in a floor, roof, or other walking/
working surface. The definition of this term is consistent with the 
proposed definition, with only minor editorial revision (the words void 
or gap are used instead of the words hole or opening). The existing 
standard defines holes and openings as separate topics; however, the 
treatment of each is essentially the same. The existing rule defines a 
floor hole as an opening less than 12 inches but more than 1 inch or 
more in its least dimension through which materials may fall; and 
defines a floor opening as a hole 12 inches or more in its least 
dimension through which persons may fall. To eliminate confusion, OSHA 
proposed to use the word ``hole'' to describe all voids and gaps (holes 
and openings) in floors, roofs, and other walking/working surfaces. The 
word ``opening'' is used later to describe voids and gaps in vertical 
surfaces such as walls and partitions.
    There were several comments on the proposed definition of 
``holes.'' One commenter (Ex. 2-140) thought the proposed definition of 
the term ``hole'' was too restrictive, assuming that the ``purpose is 
to prevent workers from falling through to lower areas.'' Other 
commenters (Exs. 2-16, 2-47, and 2-92) requested that OSHA clarify the 
definition of holes because it was unclear whether OSHA's intent was to 
regulate holes through which material or persons could fall. OSHA 
observes that its intent is to address all hazards associated with 
holes, including employees falling through and stepping into holes, as 
well the hazards of objects falling through holes onto employees. As 
noted in the proposal, OSHA chose the 2-inch least dimension for a 
``hole,'' instead of the 1-inch least dimension set in the definition 
of the existing term ``floor hole,'' because the Agency believes that 
focusing on holes which are at least 2-inches wide addresses the 
problems caused by small holes more reasonably.
    ``Infeasible'' is a new term and as used in this subpart, it means 
that it is impossible to perform the construction work while using a 
conventional fall protection system, or that it is technologically 
impossible to use a conventional system. The conventional systems are 
guardrail systems, safety net systems, and personal fall arrest 
systems. This term is being added to provide guidance to employers who 
believe it is infeasible to use conventional fall protection systems 
and wish to raise a defense of infeasibility as the reason for not 
using conventional fall protection systems. The definition has evolved 
from litigation involving contested citations where employers have 
asserted that compliance with an OSHA requirement was ``infeasible'' or 
``impossible.'' The discussion of the criteria for implementation of a 
fall protection plan (Sec. 1926.501(b)(2) of the final rule), below, 
provides further information about how OSHA is applying the new term.
    ``Lanyard'' means a flexible line of rope, wire rope, or strap 
which generally has a connector at each end for connecting the body 
belt or body harness to a deceleration device, lifeline, or anchorage. 
This definition reflects editorial revision of the proposed language. 
Two commenters, the AGC of Florida and the ISEA (Exs. 2-16 and 2-23), 
pointed out that the inclusion of ``strap webbing'' in the proposed 
definition was redundant because it is a type of flexible line already 
in the definition. OSHA has revised the definition, removing the 
redundancy. The revised language of the definition is consistent with 
the definition used in the final rule on powered platforms [54 FR 
31470].
    ``Lifeline.'' The term ``lifeline'' has been revised in the final 
rule so that it is consistent with the definition used in the final 
rule for powered platforms [54 FR 31470]. The terms ``drop lines'' and 
``trolley lines'' have been deleted. The revised definition more 
clearly expresses the function of a lifeline and its use for connecting 
other components of a personal fall arrest system. OSHA received two 
comments (Exs. 2-12 and 2-35) on the proposed definition. Both 
commenters pointed out that the proposed definition was in conflict 
with the definition of a lanyard. OSHA agrees with the commenters and 
has revised the definition to eliminate the conflict.
    ``Low-slope roof.'' OSHA is using the term ``low-slope roof'' in 
the final rule instead of the proposed term ``low-pitched roof.'' This 
change in terminology is merely an editorial correction that uses the 
proper expression to make it clear that we are describing the slope of 
the roof, not the pitch.
    ``Personal fall arrest system.'' This term replaces the term ``body 
belt/harness systems'' and means a system used to arrest an employee in 
a fall from a working level. It consists of an anchorage, connectors, a 
body belt or body harness, and may include a lanyard, deceleration 
device, lifeline, or suitable combination of these. OSHA has decided to 
replace the term ``body belt/harness system'' in an effort to keep all 
terms and definitions related to fall protection consistent throughout 
the standards. The final rule on powered platforms also contained a 
definition for personal fall arrest systems [54 FR 31470] which is 
identical to the definition in this final rule. The meaning is 
essentially the same as that proposed for body belt/harness systems, 
and the phrase ``personal fall arrest systems'' appears in the final 
rule wherever the phrase ``body belt/harness systems'' was used in the 
proposed rule. There were two comments related to the proposed 
definition ``body belt/harness systems.'' The commenters, ISEA and MSA 
(Exs. 2-23 and 2-35), both suggested rewording the definition to 
indicate that lifelines and deceleration devices are not always 
included as a part of a body belt/harness system as the proposed 
definition implied. OSHA agrees and has revised the proposed definition 
accordingly.
    ``Positioning device system.'' This term means a body belt or body 
harness system rigged to allow an employee to be supported on an 
elevated vertical surface, such as a wall, and work with both hands 
free while leaning backwards. The proposed definition was identical. 
Two commenters (Exs. 2-15 and 2-23) suggested changing the definition 
of the term ``positioning device system'' to permit such devices to be 
used on surfaces such as small horizontal ledges and steep roofs. OSHA 
observes that changing the definition would have no effect on the 
requirements to have fall protection at unprotected sides and edges of 
walking/working surfaces (e.g., ledges) or of steep roofs. The use of 
positioning device systems was not proposed for use in either of these 
situations. OSHA has no evidence that would lead it to believe that 
positioning device systems offer appropriate protection to workers on 
ledges and steep roofs, nor has the commenter provided any substantive 
information to that effect. After consideration of the record, OSHA has 
determined that the term ``positioning device systems'' is 
appropriately defined and that no further revision is necessary.
    ``Roofing work.'' This is a new term in the final rule. The term is 
defined to mean the hoisting, storage, application and removal of 
roofing materials and equipment, including related insulation, sheet 
metal, and vapor barrier work, but not including the construction of 
the roof deck. OSHA proposed to use this definition to define the term 
``built-up'' roofing work. However, many commenters pointed out that 
OSHA's definition in the proposal was incorrect as it applied to the 
term ``built-up.'' The commenters said the definition described all 
kinds of roofing work, and it was not just a definition of ``built-up'' 
roofing work. Many of the commenters represented roofing contractors 
(Exs. 2-54, 2-57, 2-68, 2-74, 2-83, 2-85, 2-88, 2-94, 2-109, 2-124, 2-
126, 2-128, 2-130, as well as others) and they wrote to support the 
position of the National Roofing Contractors Association (NRCA) (Ex. 2-
162) who pointed out the incorrect terminology.
    Other commenters (Exs. 2-91, 2-110, and 2-124) stated that the term 
``built-up roofing'' should be replaced with the term ``low-slope 
roofing,'' because ``this change will reflect a truer meaning to the 
definition to which the standard will apply.'' They also stated that 
the term defined in the proposal describes all types of roofing, not 
just built-up roofing. The commenters suggested that OSHA define ``low-
slope roofing'' to mean ``the application, installation, and/or removal 
of any roofing material or system over a roof deck or existing roof.'' 
OSHA believes that this term should apply to roof work performed on any 
roof, regardless of the slope. Accordingly, OSHA has not made the 
suggested change.
    OSHA agrees with the commenters who suggest the term ``built-up 
roofing'' needs to be deleted from the proposed rule. OSHA also agrees 
with the commenters that the proposed definition accurately defines 
roofing work in general and is defining the term roofing work as 
suggested.
    ``Rope grab'' means a deceleration device that travels on a 
lifeline and automatically engages the lifelines and locks by friction 
so as to arrest the fall of an employee. A rope grab usually employs 
the principle of inertial locking, cam/level locking, or both. This 
term was not defined in the proposed rule. It has been added to this 
final rule as in the powered platforms final rule [54 FR 31470], to 
state clearly what the Agency means when it uses ``rope grab'' as an 
example of a ``deceleration device.''
    ``Self-retracting lifeline/lanyard'' means a deceleration device 
containing a drum-wound line that may be slowly extracted from or 
retracted onto the drum under slight tension during normal employee 
movement, and that, after onset of a fall, automatically locks the drum 
and arrests the fall. This term, like rope grab, was not defined in 
proposed Part 1926, subpart M. OSHA, however, has determined that it is 
appropriate to define self-retracting lifeline/lanyard so that the term 
which is used in the definition of ``deceleration device'' is clearly 
understood. OSHA made the same determination in the final rule on 
powered platforms [54 FR 31470].
    ``Snaphook'' means a connector comprised of a hook-shaped member 
with a keeper, which is normally closed or similar arrangement. The 
``keeper'' opens to permit insertion of other hardware or of a like 
object and then, when released, automatically closes to retain the 
object. Snaphooks are generally, either locking or non-locking. Both 
types are covered in the definition of snaphook. That term was defined 
in the proposed rule for powered platforms but not in the proposal for 
subpart M.

    Note: Effective January 1, 1998, the use of non-locking 
snaphooks is prohibited for use as part of personal fall arrest 
systems and positioning device systems.

    OSHA received one comment (Ex. 2-23) on the subpart M proposal 
suggesting that the term ``snaphook'' should be defined. OSHA agrees 
with that comment because the Agency believes that the standard should 
clearly express what OSHA means when its sets requirements for personal 
fall arrest system components. In addition, OSHA notes that some of the 
comments (Ex. 3-13) and testimony addressed in the final rule on 
powered platforms suggested that the proposed definition of 
``snaphook'' should distinguish between locking and non-locking 
snaphooks [54 FR 31447]. OSHA agreed with that suggestion in the 
powered platform final rule [54 FR 31470] and revised the proposed 
definition of ``snaphook'' accordingly. That definition is identical to 
the definition used in this final rule.
    ``Work area.'' The definition is identical to the one proposed. 
OSHA notes that this definition applies to all areas where employees 
are present.
Sec. 1926.501--Duty To Have Fall Protection
    This section specifies the areas and operations where fall 
protection systems are required. The criteria to be met by fall 
protection systems, and the training necessary to use the systems 
properly, are covered in succeeding Secs. 1926.502 and 1926.503, 
respectively.
    Paragraph (a)(1). This paragraph states that section 1926.501 sets 
forth the type of fall protection systems employers must use in various 
areas and operations. In addition, it mandates that all fall protection 
systems required to be used by Sec. 1926.501 conform to the criteria 
and work practices set forth in Sec. 1926.502. OSHA notes that most of 
the provisions provide several choices for providing fall protection, 
but some provisions limit the choices. For example, only guardrail 
systems are permitted to be used to protect employees on ramps and 
runways and other walkways. In these situations, OSHA believes 
guardrail systems offer the appropriate level of fall protection and 
the record supports this conclusion.
    There were no comments specific to this paragraph. OSHA has made a 
minor editorial change for the sake of clarity. However, OSHA provides 
the following discussion to clarify further its intent under this 
general provision.
    OSHA has consistently maintained that all construction employers 
are responsible for obtaining information about the workplace hazards 
to which their employees may be exposed and for taking appropriate 
action to protect affected employees from any such hazards. ``The 
[Occupational Safety and Health Review] Commission has held that an 
employer must make a reasonable effort to anticipate the particular 
hazards to which its employees may be exposed in the course of their 
scheduled work. Specifically, an employer must inspect the area to 
determine what hazards exist or may arise during the work before 
permitting employees to work in that area, and the employer must then 
give specific and appropriate instructions to prevent exposure to 
unsafe conditions.'' Automatic Sprinkler Corp. of America, 8 BNA OSHC 
1384, 1387, 1980 CCH OSHD 24,495 (No. 76-5089, 1980), cited with 
approval in several cases, including Conagra Flour Milling Co., 15 BNA 
OSHC 1817, 1823, 1992 CCH OSHD 29,808 (No. 88-2572, 1992).
    In addition, it is well established that general contractors must 
``apprise themselves of which safety efforts their specialty 
subcontractors have chosen to make in completing their assignments.'' 
Blount Intern. Ltd., 15 BNA 1897, 1900 n. 3, 1992 CCH OSHD 29,854 (No. 
89-1394, 1992).
    OSHA considers subcontractors to have a reciprocal responsibility 
to determine what protective measures the general contractors have 
identified as necessary and have implemented. Furthermore, the same 
considerations arise at a multi-employer worksite, because each 
contractor needs to know about any hazards that other contractors may 
confront or create so that contractors can take the appropriate 
precautions for employee protection.
    OSHA requires employers to protect employees performing 
construction work from fall hazards, and sets criteria for the proper 
implementation of fall protection through the requirements in subpart M 
and the specific standards referenced in Sec. 1926.500(a)(2) and 
(a)(3). However, there is much more to workplace safety than an 
employer arriving at a work site with a copy of the pertinent standards 
in hand. Employers have a duty to anticipate the need to work at 
heights and to plan their work activities accordingly. Careful planning 
and preparation (e.g., project design that incorporates fall protection 
and employee training) lay the necessary groundwork for an accident-
free workplace.
    OSHA is aware that many falls have occurred because employers have 
not taken fall protection into account when they plan and undertake 
construction even when it is known that the work involves employee 
exposure to fall hazards. In some cases, an employer has recognized the 
hazard and established appropriate fall protection procedures, but has 
failed to ensure that employees followed those procedures. In other 
cases, employers either misidentified the hazard, selected 
inappropriate measures or completely failed to address fall hazards. 
The foreseeable consequence is that, as discussed above in the 
Background section, falls from elevations account for a large 
percentage of construction-related injuries and is the leading cause of 
death on construction jobs.
    Employers need information about the work they are to perform so 
that they can make fall protection an integral part of their projects. 
An employer's communication and coordination with customers, other 
contractors (particularly at multi-employer worksites) and suppliers 
are critical elements of that employer's ability to protect its 
employees and to avoid creating hazards for other employees. Initially, 
the employer needs to develop or obtain information regarding the work 
to be performed, so that all anticipated fall hazards are identified. 
The employer would then determine how to protect its employees from 
those hazards. For example, many employers are minimizing exposure to 
fall hazards by having anchorage points for personal fall arrest 
systems fabricated or designed into structural members and by 
installing perimeter lines on structural members before those members 
are lifted into position.
    OSHA anticipates that the trend towards providing ``100 percent 
fall protection'' will spur even more effective efforts, from the 
design stage through to project completion, to increase employee 
protection. To this end, employers will need to reexamine their 
``traditional methods'' and, when possible, update them by 
incorporating available fall protection technology and design concepts. 
OSHA believes that while there may initially be some increased costs 
and disruption associated with these efforts, subsequent productivity 
gains and reductions in the cost of workers' compensation will clearly 
make it highly cost effective in the long run to provide effective fall 
protection. (See Regulatory Impact and Regulatory Flexibility Analysis, 
Section V).
    An employer who controls its own construction projects will 
generally find it adequate to make its design and equipment decisions 
part of the project blueprints and workplan. Where employers are 
bidding a contract to perform specified construction work, making fall 
protection a bid item gives potential customers a clear idea of how 
prospective contractors plan to comply with subpart M. This is a point 
at which effective communication between a contractor and a customer is 
critical. Prospective contractors must obtain sufficient information 
from the customer to enable them to develop responsive bids, 
incorporating fall protection that complies with subpart M. By doing 
so, the bidding contractor reassures the customer that it has taken 
into account the full cost of performing the work in question. Both 
parties need to recognize that employee protection is an integral part 
of every construction project. Employers will not be permitted to gain 
a competitive advantage by exposing their workers to fall hazards.
    Paragraph (a)(2) is a new requirement added as a result of comments 
on Issue #6. In Issue #6, OSHA requested comment on whether it should 
promulgate rules requiring the inspection of work surfaces to determine 
their structural integrity prior to employees being required to work on 
such surfaces. OSHA explained that there are currently no specific 
requirements that address this concern. OSHA notes, however, there are 
general requirements in existing Sec. 1926.20(b)(2) which address 
inspections of job sites, materials and equipment by a designated 
competent person. Issue #6 asked whether or not a specific requirement 
should be added to the fall protection section that would require 
employers to take some specific action, in addition to complying with 
Sec. 1926.20(b)(2), to determine whether or not the work surfaces would 
support the weight of workers, equipment and materials, thereby 
preventing a collapse that would result in employees falling.
    Issue #6 also explained that the inspections would insure that work 
surfaces have the requisite strength to prevent collapse under the 
weight of employees, tools, and materials. The issue further stated 
that OSHA has obtained information (Ex. 3-3) which indicated that it 
was appropriate to require such inspection. That study showed that of 8 
fatalities of employees falling through ceilings, 4 of the accidents 
occurred because the work surface was not capable of supporting the 
employee's weight. The study also showed that of 55 fatalities 
resulting from falls from roof levels, 8 occurred because the employees 
were working on surfaces with insufficient structural strength to 
support their weight. OSHA asked for comments on the necessary criteria 
for inspection of surfaces, the inspection methods to be used, and the 
qualifications of the inspectors.
    In response, ACCSH recommended that a competent person certify the 
structural integrity of a working surface before employees are allowed 
to work on it. (Tr. 6/10/87; p. 109).
    The Tennessee Valley Authority (TVA) (Ex. 2-20) stated, ``Work 
surfaces should be inspected for their structural integrity prior to 
allowing employees on that surface,'' and that a qualified civil or 
structural engineer should conduct the inspection.
    The Scaffolding, Shoring, & Forming Institute, Inc. (SSFI) (Ex. 2-
89) also commented in support of an inspection provision and 
recommended that the inspection by made by a ``qualified'' individual.
    Four other commenters agreed that inspection for structural 
integrity should be required by OSHA (Exs. 2-6, 2-9, 2-36, 2-50 and 2-
99). The Egan Companies (Ex. 2-9) also recommended that periodic 
inspections be conducted in addition to initial inspection.
    Other commenters were opposed to OSHA requiring an inspection to 
determine structural integrity. For example, the Great Lakes 
Fabricators & Erectors Association (GLFEA) (Ex. 2-19) said that such a 
requirement was more properly the responsibility of building codes and 
building inspectors rather than OSHA. Bristol Steel and the National 
Erectors Association (NEA) (Exs. 2-12 and 2-43) commented that the 
requirement would be ineffective at reducing the kinds of accidents 
regulated by subpart M and that costs would far outweigh the benefits. 
The commenters further stated, ``The problem is that persons do not 
recognize hazards and respond sensibly to the situation at hand,'' 
adding that education and training would help. Miller and Long (Ex. 2-
41) stated ``* * * the working surfaces are designed by an engineer and 
erected to his specifications.'' The National Constructors Association 
(NCA) (Ex. 2-45) commented that inspections should be a part of the 
employer's quality assurance/quality control program.
    The Boston Cement Masons and Asphalt Layers Union, (BCMALU) Local 
No. 545 (Ex. 2-46) noted that work surfaces such as metal decking 
should be heavy enough to withstand the workers and equipment. They 
also commented that most metal decking jobs around Boston have to be 
shored up when concrete is placed.
    OSHA observes that the existing regulations in subpart Q (Concrete 
and Masonry Construction) and subpart R (Steel Erection) contain 
provisions requiring employers to take specific action to eliminate the 
hazards identified by the BCMALU. Section 1926.701(a) of subpart Q 
prohibits imposing loads on structures until it has been determined 
that the structure can support the load, and subpart R requires decking 
to be of sufficient strength to carry the working load 
(Sec. 1926.752(f)). Those existing provisions directly address the 
situations identified by the BCMALU.
    After considering all of the comments received on this issue, OSHA 
has determined that the record supports adding a new inspection 
requirement, more specific than that in Sec. 1926.20(b)(2). As 
discussed above, existing Sec. 1926.20(b)(2) requires, in part, that 
employers ``* * * provide for frequent and regular inspections of job 
sites, materials, and equipment to be made by competent persons 
designated by the employer.'' Revised paragraph (a)(2) will require 
employers to ensure the structural integrity of walking/working 
surfaces before employees are permitted to be on those surfaces.
    Paragraph 1926.501(b). Paragraph (b) contains 15 requirements that 
set forth the options from which employers may choose to protect 
employees exposed to fall hazards when on ``walking/working surfaces,'' 
as defined in Sec. 1926.500(b). Under paragraph (b), employers are 
required to choose and use a fall protection system (or combination of 
systems) as provided by paragraphs (b)(1) through (b)(15) which address 
the fall protection needs of particular walking and working surfaces.
    OSHA has used the term ``walking and working surfaces'' instead of 
the existing term ``floor'' to indicate clearly that subpart M 
addresses all surfaces where employees perform construction work. The 
Agency has always maintained that the OSHA construction fall protection 
standards cover all walking and working surfaces. The revised rule 
reaffirms the existing Agency interpretation and practice and clarifies 
the language of the standards in that regard. Also, OSHA has 
consistently held that subpart M addresses the hazards of falling from 
a walking/working surface to any kind of lower level (e.g., solid, 
liquid or colloid). In addition, the Agency has determined that 
compliance with revised subpart M will not conflict with Sec. 1926.106, 
Working over or near water.
    OSHA received three comments on the introductory language of 
proposed paragraph (b), including two which were in response to Issue 
#2. In Issue #2, OSHA asked if it had been overly restrictive in its 
fall protection provisions by limiting options for certain areas or 
operations. The Milwaukee Construction Industry Safety Council (MCISC) 
(Ex. 2-140) expressed the opinion that warning lines provide 
appropriate protection for workers who are not required to go near 
unprotected edges. OSHA agrees and observes that the use of warning 
lines is permitted as an appropriate method of protecting workers on 
low-slope roofs and where no workers are required to go near the 
unprotected edges. In particular, OSHA recognizes that there may be 
circumstances where the use of a warning line system is appropriate, in 
conjunction with a Fall Protection Plan, to protect workers who are not 
required to go near unprotected edges.
    The Eastern Contractors Association, Inc. (ECA) (Ex. 2-3) commented 
that ``The fall protection requirements 6 feet on open sided floors and 
10 feet on scaffolds should remain as is,'' and explained that the 
situations were different and each presented unique problems. In the 
proposed revision to subpart L, Scaffolds, the Agency proposed 
(Sec. 1926.451(e)) that employees working on scaffolds more than 10 
feet above lower levels be protected from fall hazards (51 FR 42707, 
November 25, 1986). The appropriate height threshold for fall 
protection on scaffolds will be set in the final rule for subpart L. 
The ECA also stated the height at which fall protection is required 
should be the same for all trades. OSHA agrees and this final rule 
reflects that concern.
    On the other hand, the SSFI (Ex. 2-89) recommended that the 
proposed and existing height thresholds for fall protection at 
unprotected sides and edges, low-pitched floors, roof, etc. be changed 
from 6 feet (1.8 m) to 10 feet (3.05 m). Based on the BLS injury and 
fatality data, discussed above (Ex. 3-6), OSHA believes that employees 
performing construction work on walking and working surfaces 6 feet
(1.8 m) or more above lower levels are exposed to a significant risk of 
injury and death. Accordingly, more workers would be injured or killed 
if the height threshold for fall protection were raised to 10 feet 
(3.05 m). Therefore, OSHA is not making the suggested change.
    Paragraph (b)(1) sets forth the requirements for fall protection 
from unprotected sides and edges of walking and working surfaces. It 
provides that employees must be protected when they are exposed to 
falls from unprotected sides and edges of walking/working surfaces 
which are 6 feet (1.8 m) or more above lower levels. The options from 
which an employer can choose to provide this protection are guardrail 
systems, safety net systems, and personal fall arrest systems. OSHA 
considers these three types of systems to be ``conventional fall 
protection systems.''
    Paragraph (b)(1), as promulgated, differs from proposed paragraph 
(b)(1) in several respects. In proposed paragraph (b)(1), OSHA 
distinguished between unprotected sides and edges that were at least 18 
inches (.5 m) in width, and those that were less than 18 inches (.5 m) 
in width. In particular, the proposed rule required employers to 
protect employees by the use of guardrails when the floor, roof or 
other walking and working surface was at least 18 inches (.5 m) in 
width. Where the unprotected sides and edges were less than 18 inches 
(.5 m) wide, OSHA proposed to provide more flexibility as to the method 
of fall protection by allowing employers to use personal fall arrest 
systems (body belt/harness systems) or safety net systems instead of 
guardrail systems. OSHA proposed these options because it recognized 
the feasibility problems associated with erecting guardrails on a 
surface that was less than 18 inches (.5 m) wide and, therefore, 
proposed alternative methods of protecting workers from falls. The 
proposed 18-inch (.5 m) threshold was consistent with existing 
Sec. 1926.500(d)(3) which addresses ramps and runways. In addition, the 
Agency notes that the proposed requirement that walking and working 
surfaces over 18 inches (.5 m) wide be protected at the edge with 
guardrail systems was also consistent with existing Sec. 1926.500(d)(1) 
which requires a guardrail system to be erected at every open-sided 
floor or platform, which would include the floor perimeter. Thus, the 
proposed rule and the existing rule contained essentially the same 
requirement.
    Three commenters (Exs. 2-1, 2-15, and 2-140) contended that 
proposed paragraph (b)(1) was either inappropriate or too restrictive. 
Two of the commenters cited situations where, they believed, guardrail 
systems would not be the most appropriate form of protection, and 
stated that using a personal fall arrest system is sometimes more 
appropriate. For example, the Alaska Department of Labor (Ex. 2-1) 
commented, ``In many cases workers are exposed to hazards erecting a 
guardrail system that could be avoided if they were allowed to use a 
safety line system.'' Also, as mentioned above, ISEA (Ex. 2-23) 
requested that OSHA permit the use of positioning device systems on 
surfaces such as small horizontal ledges and steep roofs. OSHA has 
determined that positioning device systems do not provide adequate fall 
protection in these situations.
    OSHA agrees with the commenters that there are work operations and 
areas with walking and working surfaces that are 18 inches (.5 m) or 
more wide (e.g., ledges and balconies) where personal fall protection 
systems or safety net systems are at least as protective as guardrails. 
Accordingly, OSHA has revised proposed paragraph (b)(1) to allow any of 
the conventional fall protection systems.
    In Issue #4, OSHA asked whether there was a distance from the 
unprotected side or edge where a worker would be safe from fall hazards 
and not need any fall protection. As an example, OSHA inquired if fall 
protection would be necessary at the perimeter of a floor if employees 
were only required to work in the center of a floor and that center 
would be as far as 10, 20, or 30 feet from an unprotected side or edge.
    The GLFEA (Ex. 2-19) recommended that employers provide fall 
protection to employees who are within 8 feet of the edge. Another 
commenter, the MCISC (Ex. 2-140), suggested that employees who work 6 
to 10 (1.8 to 3.05 m) feet from the edge would not need fall 
protection. The SSFI (Ex. 2-89) agreed with the proposed OSHA approach, 
requiring fall protection regardless of employee distance from exposed 
edge, because ``it is nearly impossible to develop a policy for most 
every situation that may or may not require guarding.''
    Miller & Long Co., Inc. (Ex. 2-41) commented, ``I feel that all 
open sided floors should have adequate fall protection because once it 
is there, the potential hazard for employees to 'wander' into an unsafe 
area is negated.'' In addition, the BCMALU (Ex. 2-46) commented, ``Who 
knows when the wind will change while you are carrying something that 
could make you like a kite or when you will or others will have to work 
near the edge.''
    The ACCSH, in its meeting on June 10, 1987, (Tr. 6/10/87; pp. 67-
88) had considerable discussion on the areas of concern addressed in 
Issue #4. The discussion began with the following statement from a 
member:

    I believe that this entire question is based on a false 
assumption. The assumption that seems to be included in it is that 
if a worker is working near the middle of a floor, he's never going 
to approach the edge of the floor. And if we know of any way to 
convince employees that that's the way they will work, I'd like to 
know what it is. Workers on any construction site are very mobile, 
and there's no effective system to keep employees from venturing 
into an unprotected danger zone * * *.
    I can't think of any job that I have ever seen where there's a 
floor or roof that will not require some work near the edge of it at 
some time during the process. The guardrail must be, the protection 
must be placed at that time and certainly there's no added cost to 
leaving that in place until the work is completed on that floor and 
some permanent protection is in existence.

    The Committee voted to recommend that guardrail systems or other 
means of fall protection be provided on any elevated work surface where 
employees were present, subject only to the exemptions that OSHA has 
now included in the final rule on subpart M.
    The Precast/Prestressed Concrete Institute (PCI) (Ex. 2-44) also 
addressed the issue of perimeter protection, stating that ``Perimeter 
protection is not really the responsibility of the * * * subcontractor; 
it is the responsibility of the general contractor to coordinate safety 
and make the workplace safe for all trades * * *.''
    OSHA has carefully evaluated the concerns expressed and has 
determined that employers should have the option to use personal fall 
arrest systems or safety net systems where those systems would be 
feasible and would protect employees from fall hazards. Whatever 
conventional system is adopted, OSHA expects the employer to implement 
it early in the construction process and to maintain that system in 
place until all work has been completed or until the permanent elements 
of the structure which will eliminate the exposure to falling hazards 
are in place. It is not OSHA's intent that individual contractors or 
subcontractors each separately provide and remove fall protection 
systems on the same floor. The general contractor in charge of the 
overall project can, and should, evaluate those situations where fall 
protection may be needed. OSHA believes, based on its knowledge of good 
industry practices, that the general contractor will contract for fall 
protection for all employees until employees are no longer exposed to 
the fall hazard. In the event that the fall protection system has been 
dismantled and workers are then required to work on the floor in an 
area away from the fall hazard, OSHA compliance staff will consider the 
extent to which individual contractors acted to prevent workers from 
leaving the work area and travelling to the unprotected edge. For 
example, a contractor could erect a guardrail system around the 
perimeter of the work area, thus providing protection from the 
unprotected sides and edges. OSHA would consider this an acceptable 
form of protection under the circumstances, provided workers remain in 
the protected area at all times.
    In conclusion, after careful and complete consideration of the 
entire record, OSHA has determined that there is no ``safe'' distance 
from an unprotected side or edge that would render fall protection 
unnecessary.
    Paragraph (b)(2) sets requirements for the protection of employees 
who are exposed to fall hazards while constructing leading edges and 
employees who are working on the same level as a leading edge, but are 
not actually engaged in constructing the leading edge. As defined in 
the final rule, a leading edge is the edge of a floor, roof, or 
formwork that changes location as additional floor, roof, or formwork 
sections are placed, formed, or constructed. Leading edges not actively 
and continuously under construction are considered to be ``unprotected 
sides and edges,'' and are covered by paragraph (b)(1).
    Paragraph (b)(2)(i) of the final rule requires that employers 
protect employees actively engaged in constructing leading edges from 
fall hazards through the use of guardrail systems, safety net systems, 
or personal fall arrest systems. In addition, paragraph (b)(2)(i) 
provides that if the employer can demonstrate that it is infeasible or 
would create a greater hazard to use any of these systems, the 
employers must develop and implement a fall protection plan which meets 
the requirements of paragraph (k) of Sec. 1926.502. The fall protection 
plan, in turn, requires, among other criteria and conditions for use, 
that the employer designate all areas where conventional fall 
protection systems cannot be used as controlled access zones. Employers 
must also implement a safety monitoring system in those zones if no 
other alternative measure has been implemented. Criteria for controlled 
zone systems and safety monitoring systems are found in Sec. 1926.502 
(g) and (h), respectively.
    Paragraph (b)(2)(ii) requires that employees on walking/working 
surfaces where leading edges are under construction, but who are not 
constructing the leading edge, shall be protected from fall hazards by 
guardrail systems, safety net systems or personal fall arrest system.
    The leading edge provisions of the final rule differ from the 
proposed rule. In the proposal, OSHA explained its belief that a 
requirement to erect safety net systems would not always be feasible 
because of insufficient room to rig a safety net and because the net 
would have to be constantly moved, exposing workers repeatedly to fall 
hazards while erecting the net.
    OSHA also noted that because the time lapse between placement of 
successive floor, roof, or floor formwork sections would often be only 
a few minutes, guardrail systems erected along a leading edge would 
have to be removed almost as soon as they were erected to allow 
placement of the next section. In addition, OSHA noted, the continued 
erection and removal of guardrail systems could pose a ``greater 
hazard'' to the employees than having the employees work without the 
guardrails. Because of this, OSHA was concerned that guardrail systems, 
as required in the existing rule, often would not allow the 
accomplishment of work along leading edges.
    Finally, OSHA expressed its view that personal fall arrest systems 
(body belt and harness systems) might limit an employee's freedom of 
movement, hindering job performance as well as impairing an employee's 
ability to avoid hazardous situations (such as a misdirected incoming 
piece of concrete or other structural member used on the leading edge). 
Also, during the erection of some structural members, employees are 
required to walk along a leading edge during placement of the member. A 
personal fall arrest system (body belt or harness system) might impede 
this effort if the employee's movement was restricted by the length of 
the lanyard, causing constant reattachment of the systems to different 
anchor points.
    In recognition of these potentially infeasible (impossible to 
perform the work) or greater hazard situations, OSHA proposed to allow 
the use of a fourth option--safety monitoring systems on leading edges 
and the use of control zone systems to limit the number of employees 
exposed to the hazard at leading edges.
    There were several varied comments on the proposed leading edge 
provision. NIOSH (Ex. 2-33 and 27-6) questioned the adequacy of the 
safety monitoring system, noting that it relied on visual inspection 
only, and recommended that it be deleted as a fall protection option. 
NIOSH also stated that using a monitor would require active involvement 
of both the monitor and the worker to ensure safety.
    Miller & Long (Ex. 2-41) noted that, ``The only employees at the 
leading edge are the ones who are working on the leading edge. 
Therefore, the warning lines and monitor systems are not needed.''
    The Daniel Marr & Son Co. (Ex. 2-40), specifically addressing the 
concerns of ironworkers installing decking, also commented on the 
safety monitoring system for leading edge work, noting that, ``By 
requiring a worker to act as a monitor, the Department of Labor will be 
forcing steel erection companies to duplicate safety efforts and, at 
the same time, be placing a large financial burden on the construction 
industry.'' OSHA notes that at this time, the final rule for subpart M 
does not apply to steel erection activities in buildings. The Agency 
has begun work with the Steel Erection Negotiated Rulemaking Advisory 
Committee to develop a proposed revision for subpart R which will 
address fall protection for employees performing steel erection 
activities in buildings [see meeting notice at 59 FR 25848 and 59 FR 
26153].
    Finally, WMACSA (Ex. 2-56) wanted to know how the leading edge 
provision applied to workers setting precast stone walls on the leading 
edge. In response, OSHA observes that the leading edge provision would 
not be applicable in the situation described. That is, if a wall is 
being set at the edge, the leading edge of the floor or roof or 
formwork is no longer under construction. Therefore, the work location 
(the edge) would be considered an unprotected side and edge and covered 
by paragraph (b)(1), above.
    The final rule differs from the proposed rule in that it requires 
the use of one of the three conventional fall protection systems, but 
does not permit an employer to use a safety monitoring system instead 
of one of the conventional systems as was proposed. However, as noted 
above, when the employer demonstrates that all conventional fall 
protection systems are infeasible (i.e., it is impossible to perform 
the construction work or technologically impossible to use) or create a 
greater hazard, the final rule requires the employer to develop and 
implement a fall protection plan. A fall protection plan, in turn, 
requires the employer to establish a controlled access zone and to 
implement a safety monitoring system if no other alternative measure 
has been implemented in the zone where conventional fall protection is 
not being used.
    A controlled access zone, discussed in detail in Sec. 1926.502(g) 
below, is defined with control lines to form a visual and physical 
barrier which, in this case, prevents an employee from inadvertently 
entering the area immediately adjacent to the leading edge. OSHA notes, 
again, that any unprotected side or edge of the floor or roof which is 
not part of the controlled access zone must be guarded as required by 
the pertinent provisions of Sec. 1926.502(b) or other protection 
provided to employees who may be exposed to falls from those other 
unprotected sides or edges. Criteria for safety monitoring systems can 
be found in Sec. 1926.502(h).
    A safety monitoring system does not provide a physical means of 
preventing falls or arresting a fall, and therefore, will not provide 
protection equivalent to that provided through the use of the other 
fall protection measures proposed.
    Accordingly, OSHA has removed these systems as a direct alternative 
to conventional fall protection systems under the general rule for 
leading edge work. However, as discussed above, the final rule requires 
the use of a fall protection plan that complies with Sec. 1926.502(k) 
where the employer can demonstrate that the use of conventional fall 
protection would be infeasible or would create a greater hazard. The 
following information is provided to assist employers in determining if 
the use of conventional fall protection would be infeasible or pose a 
greater hazard at a particular work area or for a particular operation.
    OSHA considers a fall protection measure to be infeasible when the 
employer establishes that application of that measure is either 
functionally unworkable or would prevent the performance of required 
work. The Agency recognizes that there are situations where one or 
another measure cannot be implemented, because of the configuration of 
the worksite (for example, where structures are built so close together 
that nets cannot be installed) or due to circumstances during a 
particular phase of the construction process (for example, where work 
at the leading edge precludes the use of guardrails).
    OSHA has consistently maintained, however, that, in general, at 
least one of the three conventional fall protection measures mandated 
by subpart M can be used to protect employees at a particular worksite 
from fall hazards. In particular, the Agency has frequently found that 
the use of personal fall arrest systems is feasible even where a 
guardrail system or safety net system is infeasible. Further, equipment 
is generally available to provide safe anchorage points for personal 
fall arrest systems. It is in this area that preplanning of the 
construction project is most critical. Focusing on fall protection at 
the design and planning stages of a construction project will enable an 
employer to develop measures that protect affected employees from fall 
hazards.
    OSHA recognizes that the applicability of alternative measures will 
depend on the circumstances of particular employers and work sites and 
that those circumstances vary widely. Therefore, paragraph (b)(2), like 
the provisions at Secs. 1926.501 (b)(12) and (b)(13), sets general, 
rather than specific, criteria for an employer who seeks to determine 
if it is appropriate to implement a fall protection plan that complies 
with 29 CFR 1926.502(k).
    OSHA has consistently maintained that employers must consider the 
safety of workers as well as the technical aspects of their 
construction projects. In a case involving existing Sec. 1926.105(a), 
the 5th Circuit of the U.S. Court of Appeals has stated ``[t]he 
regulation in question . . . specifically dictates the employer's duty 
to supply fall protection. The duty to consider alternative methods of 
construction which permits compliance with the regulation is merely a 
corollary of the duty to comply. The petitioner has attempted to 
characterize this duty as a burden requiring changes in methods of 
construction; however, that characterization ignores the employer's 
initial responsibility to comply with OSHA regulations. If an employer 
were permitted to choose any method of construction, and subsequently 
argue that compliance with OSHA regulations was impossible because of 
the method of construction chosen, then the regulations could be 
undermined in many instances.'' Cleveland Consol. v. OSHRC, 649 F.2d 
1160, 1166 (5th Cir. 1981). In addition, regarding an employer's duty 
to anticipate and determine the need for fall protection, the 
Occupational Safety and Health Review Commission has held that the 
employer ``could have easily foreseen the lack of open steel, given the 
problem some foresight, and installed a static line in advance.'' A.C. 
Dellovade, Inc., 13 BNA OSHC 1017, 1020 (No. 83-1189, 1987).
    OSHA has long acknowledged that there may be circumstances at a 
particular workplace which would make it unreasonable for the Agency to 
pursue a citation. In the enforcement context, OSHA has consistently 
placed the burden on the employer in question to establish any such 
circumstances as ``affirmative defenses'' to OSHA citations. The Agency 
has had considerable experience in evaluating employers' efforts to 
establish affirmative defenses (e.g., ``impossibility'' (sometimes also 
known as ``infeasibility'') and ``greater hazard'' defenses) to 
citations. Based on that experience, OSHA developed Section V.E of the 
Field Operations Manual (FOM) to guide OSHA personnel in assessing 
those defenses.
    Under Section V.E.3.b of the FOM, an employer has established 
``impossibility'' when ``Compliance with the requirements of a standard 
is: (1) Functionally impossible or would prevent performance of 
required work; and (2) There are no alternative means of employee 
protection.'' Under Section V.E.3.c, an employer has established 
``greater hazard'' when ``Compliance with a standard would result in 
greater hazards to employees than non-compliance and: (1) There are no 
alternative means of employee protection; and (2) An application [for] 
a variance would be inappropriate. Under Section V.E.3.d, an OSHA 
compliance officer who becomes aware that an employer is raising an 
affirmative defense is directed to gather pertinent information and to 
bring any possible defenses to the attention of his or her supervisor. 
That section further provides that a citation is not issued when OSHA 
determines that each and every element of an affirmative defense is 
present.
    Paragraph (b)(2), as well as Secs. 1926.501 (b)(12) and (b)(13), 
discussed below, reflect the Agency's longstanding position, as 
presented in the FOM, regarding the criteria for an employer to 
successfully establish the pertinent affirmative defenses.
    OSHA considers compliance with a measure to be ``infeasible'' when 
it is technologically impossible to do what a standard requires or when 
following the standard would prevent performance of the work in 
question. A contractor attempting to establish infeasibility will be 
required to establish the worksite-specific circumstances that preclude 
reliance on conventional fall protection to protect employees from fall 
hazards. For example, the employer will be required to establish that 
the available personal fall arrest systems cannot be used in a 
particular work area due to design or equipment constraints. The 
employer will need to indicate the particular problem (such as 
inability to provide safe anchorage; danger of lifeline entanglement; 
likelihood that lifelines, especially self-retracting lifelines, will 
be mired in grout; likelihood that completion of work would be 
prevented by fall protection; and inability of personal fall arrest 
systems to function due to the configuration of the work area for OSHA 
to determine that the employer has made the necessary showing for use 
of a fall protection plan. It will not be sufficient for the employer 
to merely assert that it is impossible to use fall protection 
equipment. Non-mandatory Appendix E provides guidance regarding the 
kind of considerations employers would take into account in attempting 
to comply with Sec. 1926.501(b)(2), (b)(12) or (b)(13).
    The Agency does not consider ``economic infeasibility'' to be a 
basis for failing to provide conventional fall protection for employees 
constructing leading edges, erecting precast concrete members, or 
performing residential construction work. The Agency has consistently 
maintained, and the record for this rulemaking shows, that the industry 
can either absorb the costs of compliance with revised subpart M or 
pass those costs along to its customers. It is well established that 
all employers must comply with OSHA's standards whether or not they are 
inspected or cited by the Agency. A.E. Burgess Leather Co., 5 O.S.H. 
Cas. (BNA) 1096, 1097 n. 2 (Review Commission 1977), aff'd 576 F.2d 948 
(1st Cir. 1978).
    OSHA has also consistently maintained that ``impracticality'' does 
not excuse a contractor from compliance with the requirements for fall 
protection. However, based on OSHA's statutory mandate to protect 
employee safety and health and to address the significant risks posed 
by fall hazards, it is reasonably necessary and appropriate to require 
the protective measures set forth in this standard. As the RIA clearly 
shows, the requirements of revised subpart M are both technologically 
and economically feasible for the construction industry and they allow 
for those limited situations in which feasibility may be an issue.
    As noted above, OSHA has acknowledged that there are situations 
where the implementation of a particular fall arrest system would 
create a ``greater hazard'' for employees than they would otherwise 
encounter. Under current Agency practice, an employer establishes the 
``greater hazard'' defense to a citation by demonstrating that the 
hazards created by compliance with a standard are greater than those 
created by non-compliance. The Agency is aware that there are workplace 
situations where the installation of guardrails or safety nets could 
involve more risk, due to the nature or duration of the exposure, than 
the work for which protection is required. On the other hand, OSHA has 
found that, as with the ``infeasibility'' defense, the ``greater 
hazard'' defense does not generally excuse an employer from protecting 
its affected employees with personal fall arrest systems. In 
particular, the Agency has found that careful planning of a 
construction project enables the employer to erect buildings/structures 
into which the necessary anchorage points for personal fall arrest 
systems have already been engineered. For example, in the case of 
precast concrete erection, preplanning may allow for lifting inserts to 
be designed so that they function as both anchorage points for personal 
fall arrest systems and as lifting inserts.
    OSHA further acknowledges that, regardless of an employer's ability 
to preplan for fall protection, there may be cases where the 
installation or use of personal fall arrest systems poses a greater 
hazard than that to which employees performing the construction work 
would otherwise be exposed. The Agency will expect an employer who 
seeks to make that case to indicate specifically how compliance with 
the requirement for personal fall arrest systems would pose a greater 
hazard. OSHA will assess each such case on its particular merits.
    Paragraph (b)(3) sets fall protection requirements for employees in 
hoist areas of walking and working surfaces that are 6 feet (1.8 m) or 
more above lower levels. Employees shall be protected through the use 
of guardrail systems or personal fall arrest systems. If guardrails (or 
chains or gates if they are being used in lieu of guardrails at the 
hoist area) are removed to facilitate hoisting operations, then 
employees who lean through the access opening or out over the edge of 
the access opening to perform their duties shall be protected by the 
use of personal fall arrest systems.
    This provision, essentially identical to the proposed provision, is 
based on existing Sec. 1926.500(g)(5), which addresses the same hazard 
but applies only to material hoisting operations on low-pitched roofs 
during built-up roofing operations. The proposal extended the existing 
requirement to all situations where equipment and material hoisting 
operations are being carried out on floors and other walking/working 
surfaces. The wording of the proposed provision has been revised for 
the sake of clarity.
    There were two comments on this provision. The WMACSA (Ex. 2-56) 
commented that the term ``hoist areas'' needed to be defined for the 
sake of clarity. In addition, the SSFI (Ex. 2-89) requested that OSHA 
interpret the ``exception'' in proposed paragraph (b)(3), because ``the 
paragraph seems ambiguous.'' OSHA believes that it has responded to the 
concerns of both commenters by rewording the provision to state more 
clearly which type of fall protection may be used at hoist areas. The 
revised provision clearly differentiates between working in the area 
where hoisting activities will take place (e.g., the area where 
materials are to be landed) and taking part in the actual hoisting 
operation (e.g., receiving materials hoisted by a crane). The exception 
language used in the proposal has been incorporated into the text of 
final rule paragraph (b)(3) so it is clear that during hoisting 
operations employees must be protected by personal fall arrest systems 
if they lean through the access opening or out over the edge to receive 
or guide materials. Otherwise, the employer would use either guardrail 
systems or personal fall arrest systems to protect workers at hoist 
areas.
    Paragraph (b)(4) of the final rule requires that employees be 
protected from hazards associated with holes. In particular, employees 
may be injured or killed if they step into holes, trip over holes, fall 
through holes or are hit by objects falling through holes. Some 
workplaces may present all of these hazards while others may have only 
one of them. The proposed rule has been revised to indicate clearly 
which protective measures are applicable to a particular hole 
situation. OSHA notes that covers which comply with the criteria of 
Sec. 1926.502(i) will protect employees from all of the above-described 
hazards.
    Paragraph (b)(4)(i) requires that employees be protected from 
falling into or through holes (including skylight openings) 6 feet (1.8 
m) or more above lower levels by covers over the hole, erecting a 
guardrail system around the hole, or by the use of a personal fall 
arrest system. The Agency has revised the proposed rule to include 
personal fall arrest systems as an acceptable fall protection option 
because OSHA believes that a properly rigged system can protect an 
employee from falling though a hole. Paragraph (b)(4)(ii) requires that 
employees be protected from tripping in or stepping into holes by 
covers; and paragraph (b)(4)(iii) requires that employees be protected 
from objects falling through holes by covers.
    The final rule differs from the proposed rule, which was based on 
requirements in the existing standards in Sec. 1926.500(b). The 
existing standard contains separate specific rules for guarding floor 
openings and floor holes in various walking/working surfaces. In the 
proposed rule, OSHA treated most holes as presenting the same type of 
hazard and did not address each individual type of hole separately. The 
proposed rule also set very specific requirements for the use of 
covers.
    In addition, the proposed rule was apparently unclear with regard 
to requirements for protecting workers from stepping and tripping into 
holes and for protecting workers from objects falling through holes. 
While it appeared the regulatory language of the proposed rule limited 
protection from holes to just those situations where employees could 
fall to 6 feet or more to lower levels, the explanatory discussion of 
the provision in the preamble to the proposed rule indicated it was the 
Agency's intent ``that all holes . . . be guarded. . . .'' (51 FR 
42722). The inconsistency was brought to OSHA's attention by a comment 
from AGC representatives (Exs. 2-16, 2-47, and 2-92), who pointed out 
that there was a need to clarify the definition or the requirement. 
Their concern was whether the Agency intended to cover holes into which 
employees could fall or holes through which materials could fall.
    The California Department of Industrial Relations (CAL/OSHA) (Ex. 
2-15) suggested that OSHA allow a standby employee safety monitoring 
system in lieu of guardrails when covers were being removed for short 
duration work. The commenter stated that it was unrealistic to require 
a guardrail where a cover is removed for passage of equipment and 
material for a short duration, where a standby employee could guard the 
hole. As discussed above at ``leading edges,'' the use of safety 
monitoring systems is thought to be the least protective of all the 
systems permitted by the final rule. For this reason, OSHA has limited 
the situations where the use of safety monitoring systems is acceptable 
to roofing operations on low-sloped roofs and to situations where the 
employer can demonstrate that it is infeasible or creates a greater 
hazard to use conventional fall protection systems and that employer 
has developed a fall protection plan. OSHA does not recognize a safety 
monitoring system as an acceptable means of protecting workers exposed 
to falling into or through holes. There are other, more protective 
measures that can be taken to address falls at holes, including covers, 
guardrail systems and personal fall arrest systems, therefore, OSHA is 
not permitting the use of the less protective safety monitoring system 
at holes. Additionally, the final rule reflects the current industry 
practice with regard to protecting workers exposed to holes and OSHA 
does not have any basis for reducing the level of protection.
    For clarification, OSHA does not intend that a guardrail be erected 
around holes while employees are working at the hole, passing 
materials, etc. Therefore, if the cover is removed while work is in 
progress, guardrails are not required because they would interfere with 
the performance of work. When the work has been completed, the employer 
will be required to either replace the cover or erect guardrails around 
the hole.
    Other comments (Exs. 2-31 and 2-56) concerned securing holes and 
these are discussed later in this preamble along with other comments on 
the criteria for covers which is addressed in paragraph 
Sec. 1926.502(i). These comments prompt OSHA to remind employers and 
employees that this paragraph (like other paragraphs in Sec. 1926.501) 
only specifies the ``duty'' requirement to have fall protection. Once 
an employer has chosen from among the options provided to meet this 
duty, he or she must then meet the requirements in Sec. 1926.502, which 
sets the criteria and conditions for use for each of the various fall 
protection systems required to be used in Sec. 1926.501.
    Many commenters responded to Issues #2 and #7, which raised 
questions and concerns related to guarding holes and the criteria for 
covers used to guard holes. For example, the Associated Builders and 
Contractors, Inc. (ABC) (Ex. 2-51) commented that they found the 
provision limiting protection to covers or guardrails was unnecessarily 
restrictive because a guardrail system around a 3-inch hole would 
require a 3-foot diagonal guardrail. OSHA observes that the proposed 
provision was framed in performance-oriented language so that employers 
would have had the flexibility to choose between guardrails and covers, 
based on the circumstances at the workplace. OSHA believes that 
compliance with paragraph (b)(4) of the final rule, whichever method is 
chosen, will protect employees appropriately. OSHA anticipates that 
employers will use guardrails only in those cases where the size and 
configuration of the hole indicate that the use of a guardrail would be 
appropriate. The ABC also suggested that the final rule allow the same 
protection for holes as OSHA proposed for leading edges. As discussed 
above, OSHA has revised the proposed rule to allow the use of personal 
fall arrest systems where an employee may fall through a hole, but OSHA 
has not allowed the use of safety monitoring systems to protect 
employees from falling through holes.
    Bristol Steel & the NEA (Exs. 2-12 and 2-43) stated that ``Covers 
can be more hazardous than no protection at all because workers can see 
an uncovered hole but they can unintentionally remove a cover and step 
into a hidden hole.'' In addition, they stated that ``. . . guardrails 
provide a false sense of security'' because ``Maintenance of guardrails 
is a serious problem when various workers are constantly altering, 
damaging, or temporarily removing them.'' OSHA observes that it has 
revised proposed Sec. 1926.502(i) to require that covers be ``secured'' 
when installed to prevent their being easily removed or accidentally 
displaced. This change should eliminate the commenters' concerns with 
regard to unintentional removal of covers.
    Both commenters suggested control zones to keep workers at a safe 
distance from holes, advocating (like the ABC, (Ex. 2-51)) that 
paragraph (b)(4) address holes the same as the proposed paragraph 
(b)(2) treated leading edges, allowing the use of guardrail systems and 
safety monitoring systems, among other options. Finally, both Bristol 
Steel and the NEA stated that the use of ``attending persons'' at 
unguarded holes was ``impractical and dangerous . . . because it is so 
difficult to enforce and so easy to let lapse during a critical 
moment'' that ``Safety monitors for workers performing the work and 
control zone systems for other workers in the area should be considered 
minimum safety precautions.'' As noted above, the Agency shares the 
commenters' concerns about the adequacy of the protection provided by 
safety monitoring systems.
    Based on review of the comments, OSHA has concluded that the 
feasibility concerns that led the Agency to allow use of controlled 
access zones and safety monitoring systems are not present with regard 
to holes. Further, OSHA does not believe that the use of controlled 
access zones and safety monitoring systems would adequately protect 
employees working in proximity to holes.
    Paragraph (b)(5) requires employees working on formwork and 
reinforcing steel 6 feet or more above lower levels to be protected by 
a personal fall arrest system, safety net system or positioning device 
system. This provision is identical to proposed Sec. 1926.501(b)(5). In 
addition, OSHA notes that with one exception (discussed below), 
paragraph (b)(5) presents the same requirement currently found in 
Sec. 1926.701(f)(2) of the concrete and masonry standard. The 
requirement in Sec. 1926.701(f)(2) is being relocated to subpart M 
because, as explained earlier, OSHA is consolidating virtually all 
construction fall protection requirements in subpart M, Fall 
Protection.
    As OSHA explained in the proposal, positioning devices are 
essentially body belts or body harnesses that are attached by short 
lanyards to the work surface, allowing a worker to perform a job with 
both hands free. While existing Sec. 1926.701(f)(2) does not provide 
for the use of positioning devices, OSHA has determined that such 
devices, used in compliance with Sec. 1926.502(e) of the final rule, 
will provide appropriate protection for affected employees. As stated 
in the proposal, because of the short length of the lanyard 
(approximately 9 to 18 inches, depending on how it is rigged), the use 
of positioning devices does not pose a significant fall hazard. The 
criteria for positioning devices systems as provided by 
Sec. 1926.502(e) are discussed below.
    Paragraph (b)(6) requires ramps, runways, and other walkways to be 
equipped with guardrails. As discussed below, the final rule is 
essentially the same as the proposed rule and is very similar to 
existing Secs. 1926.500(d)(2) and 1926.651(l)(1), which address fall 
protection for runways and excavations, respectively.
    OSHA proposed to revise existing Sec. 1926.500(d)(2) by changing 
the 4-foot threshold for fall protection to a 6-foot threshold, so that 
this provision limit conforms with the other fall protection 
provisions. In addition to ramps and runways, the proposal was expanded 
to include all walkways and bridges where a fall hazard exists, not 
just those over excavations addressed in the existing rules. OSHA notes 
that existing Sec. 1926.651(l)(1) of the excavation standards is also 
being revised to make it clear that guardrails on walkways built over 
excavations must meet the requirements of revised subpart M.
    OSHA has revised proposed paragraph (b)(6) by removing the word 
``bridges'' from the list of surfaces covered by the provision. The 
removal of the word ``bridges'' was prompted by a comment from the 
Wisconsin Road Builders Association (WRBA) (Ex. 2-154) which pointed 
out that they had been engaged in bridge building for over 40 years and 
that their company uses body belts 90 percent of the time and harnesses 
10 percent of the time when working on bridges over water. OSHA was 
unsure whether this commenter was objecting to the requirement of the 
proposal which specifically required ``guardrails'' on bridges used as 
walkways, or if the commenter was suggesting that body belts be allowed 
to protect workers crossing over bridges. In any event, the comment 
alerted OSHA that the term ``bridges'' as used here could be understood 
to mean bridges other than those used as walkways. The Agency notes 
that paragraph (b)(6) does not apply to the use of personal fall arrest 
systems or safety net systems to protect workers from falling while 
bridges are being constructed. Rather, Sec. 1926.501(b)(1) covers 
bridges under construction, and it requires employers to protect 
employees from falls off unprotected sides and edges of bridges with 
guardrail systems, safety net systems, or personal fall arrest systems. 
OSHA believes that only guardrails can provide appropriate fall 
protection for workers as they cross over ramps, runways and other 
walkways.
    Another commenter (Ex. 2-56) suggested that OSHA define ``ramps, 
walkways and bridges,'' pointing out that ``walkways'' is defined as a 
part of a scaffold in the proposed scaffold standard. As the commenter 
pointed out, a definition for ``walkways'' has been provided in the 
scaffold regulations because the term has a unique meaning as it 
applies to scaffolds. The Agency notes that a definition in subpart L 
does not apply to terms used in subpart M. OSHA has determined that 
there is no need to define the terms based on the Agency's belief that 
the use of the terms--ramps, runways, and walkways--in this subpart is 
consistent with the definitions provided by any standard dictionary.
    Paragraph (b)(7) requires that the edges of excavations which are 
not readily seen (i. e., concealed from view by plant growth, etc.) be 
protected with guardrail systems, fences, or barricades to prevent 
employees from falling into them if the excavation depth is 6 feet or 
more. In addition, walls, pits, shafts, and similar excavations with 
depths of 6 feet or more shall be guarded to prevent employees from 
falling into them. The only difference between the proposed 
requirements and the final rule is that the option to use signs as an 
alternative means of protection has been removed. The final rule is 
also essentially the same as the existing requirement in 
Sec. 1926.651(l)(2), which is being removed from subpart P and 
incorporated into subpart M because it addresses fall protection. As 
OSHA explained in the proposal, although employers are not generally 
required to provide guardrail systems at excavations, the Agency 
believes that barricades are necessary for excavations that are 
obscured from view, because of plant growth or other barriers, when the 
fall distance is at least 6 feet.
    In response to the proposal and to Issue #12, regarding the use of 
signs as an alternative to barricades at obscured excavations, CAL/OSHA 
and the State of Maryland (MOSH) (Exs. 2-15 and 2-31) objected to the 
use of signs as a means of protecting employees from falling into 
excavations. MOSH (Ex. 2-31) contended that excavations and trenches 
should be guarded whether they can be seen or not. That view was echoed 
by commenters (Exs. 2-19, 2-46, and 2-99) who stated, in addition, that 
signs alone were not effective.
    Another commenter, the Tennessee Valley Authority (TVA) (Ex. 2-20), 
commented that ``Signs can be useful as an indicator of a hazard but 
should only be used in conjunction with other measures to provide 
employee protection.'' Yet another commenter, the National Constructors 
Association (NCA) (Ex. 2-45), commented that ``the use of physical 
barriers to prevent access to high exposure areas has been sufficient 
and [we] do not see any need for new requirements.''
    On the other hand, some commenters (Exs. 2-16, 2-47, and 2-92) 
supported the use of signs, noting they had ``* * * been used 
successfully for this purpose in the past, depending upon the type 
exposure or particular situation.'' Some other commenters (Exs. 2-12 
and 2-43) recommended that OSHA promulgate the standard as proposed. In 
addition, some commenters (Exs. 2-16, 2-47, 2-92, and 2-140) suggested 
that the requirement belonged in the excavation subpart. (OSHA's 
reasons for placing most fall protection provisions in subpart M have 
been discussed earlier in this preamble).
    The SSFI (Ex. 2-89) supported the use of signs when no other fall 
prevention measures could be utilized. They also supported signs in 
conjunction with other measures. The ACCSH recommended that obscure 
excavations be protected not only by barricades and warning signs, but 
with lights if needed for nighttime operation. (Tr. 6/10/87; pp. 134-
135).
    Based on its review of the record, OSHA agrees with those 
commenters who have stated that signs, alone, would not adequately 
protect employees and has revised proposed paragraph (b)(7) 
accordingly.
    Paragraph (b)(8) requires employers to protect employees from 
falling onto dangerous equipment. Paragraph (b)(8)(i) provides that 
where a floor, roof, or other walking or working surface is less than 6 
feet above such hazards, employees shall be protected by guardrails or 
equipment guards that shield the hazard. Paragraph (b)(8)(ii) requires 
that employers protect employees on floors, roofs, and other walking or 
working surfaces 6 feet or more above dangerous equipment with 
guardrail systems, personal fall arrest systems, or safety net systems. 
``Dangerous equipment'' is defined in Sec. 1926.500(b) as equipment 
such as pickling or galvanizing tanks, degreasing units, machinery, 
electrical equipment and other units which, as a result of form or 
function, may be hazardous to employees who fall onto or into such 
equipment. These requirements are identical to the proposed provisions, 
which were based on existing provisions in Sec. 1926.500(d) (4) and 
(5).
    There was one comment on this provision. The SSFI (Ex. 2-89), 
directing its comment to paragraph (b)(8)(ii), stated ``It is 
recommended that all employees above dangerous equipment be protected 
by a guardrail system or by body belt/harness system or safety net 
system. There should be no limitations regarding the height in which 
the employee should be protected.''
    The SSFI did not further elaborate on their comment. OSHA observes 
that the two requirements of this paragraph differ in the options from 
which employers must choose to protect employees based on the distance 
between the employee and the dangerous equipment with which the 
potential for contact exists. OSHA proposed only two options--the use 
of guardrail systems or the use of equipment guards--where the fall 
distance is less than 6 feet (1.8 m) because the use of safety net 
systems or personal fall arrest systems would not be appropriate. 
Specifically, the Agency believes that if a personal fall arrest system 
or a safety net system conforming to the criteria in Sec. 1926.502 were 
used where the fall distance is less than 6 feet, the employee's fall 
may not be arrested before contact was made with the equipment. On the 
other hand, where ample distance exists, i.e., more than 6 feet (1.8 
m), the conventional fall protection systems would all be protective. 
By contrast, equipment guards would not be an appropriate option 
because they would not protect employees from such falls. For the 
reasons stated above, OSHA proposed options that it considered most 
appropriate to protect employees taking into consideration the fall 
distances and hazards involved. OSHA believes that paragraph (b)(8), as 
proposed, appropriately addresses the pertinent hazard. Therefore, OSHA 
promulgates paragraph (b)(8) unchanged.
    Paragraph (b)(9) addresses the fall protection requirements for 
employees engaged in overhand bricklaying operations and related work, 
except as set in Sec. 1926.451(g)(1)(vii). These employees are involved 
in the construction of masonry walls and must lean over the wall to 
complete the joint work. Related work, as used in this paragraph, means 
mason tending as well as electrical work that must be incorporated into 
the brick wall during the bricklaying process.
    Paragraph (b)(9)(i) requires that employees performing overhand 
bricklaying and related work 6 feet (1.8 m) or more above lower levels 
to be protected by guardrail systems, safety net systems, personal fall 
arrest systems, or they must work in a controlled access zone. However, 
when these employees are reaching more than 10 inches (25 cm) below the 
level of the walking/working surfaces, only guardrail systems, safety 
net systems or personal fall arrest systems are permitted to be used 
under paragraph (b)(9)(ii), controlled access zones are not acceptable 
in this situation.
    OSHA has repeatedly stressed that employees exposed to the risk of 
falling should, in general, be protected by one of the three 
conventional systems--guardrail systems, safety net systems and 
personal fall arrest systems. However, OSHA also recognizes that the 
use of such systems sometimes is not feasible when overhand bricklaying 
and related operations are taking place. In particular, guardrails may 
interfere with the performance of work; safety net systems often cannot 
be safely attached to or supported by the structure; and personal fall 
arrest systems often become tangled or pose serious trip and fall 
hazards. After extensive consultation with the Mason Contractors of 
America, the International Union of Bricklayers and Allied Craftsmen, 
the Laborer's International Union of North America, and the ACCSH, OSHA 
proposed to allow the use of a control zone (now referred to as a 
controlled access zone), as an additional option that could be used in 
those situations where conventional fall protection systems were not 
feasible and the employees were not reaching more than 10 inches (25 
cm) below the walking/working level.
    The criteria for controlled access zones are set in 
Sec. 1926.502(g). In brief, a control zone line prevents non- overhand-
bricklaying employees from inadvertently entering the area immediately 
adjacent to the fall hazard and the controlled access zone designates 
the area where overhand bricklaying may be performed without the use of 
guardrails, safety nets, or personal fall arrest systems as fall 
protection. However, paragraph (b)(9)(ii) provides that whenever an 
overhand bricklayer reaches more than 10 inches (25 cm) below the 
walking or working surface, the bricklayer must be protected by one of 
the ``conventional'' systems listed in paragraph (b)(9)(i)--guardrail 
systems, safety net systems or personal fall arrest systems. When OSHA 
proposed this requirement, it explained it was doing so because it 
believed that the additional leaning presents a sufficient additional 
fall hazard to warrant such protection. OSHA anticipates that employers 
will comply with paragraph (b)(9)(ii) by having employees use personal 
fall arrest systems that will restrain employees from falling to lower 
levels.
    It is important to note that controlled access zones are not 
permitted to be used as protection for employees performing overhand 
bricklaying and related work who are exposed to fall hazards associated 
with hoist areas; holes; ramps, runways, and other walkways, and 
dangerous equipment. In these situations, fall protection must be 
provided by compliance with the paragraphs addressing the specific 
hazard, (i.e., paragraphs (b)(3), (4), (6), and (8)), as appropriate. 
For example, a worker performing overhand bricklaying work near a floor 
hole would have to be protected as required by paragraph (b)(4) even 
when the hole is located within the area marked by a control zone line. 
Another example is a worker performing overhand bricklaying work above 
dangerous equipment. The provisions of paragraph (b)(8) would apply; a 
controlled access zone would not be an acceptable method of fall 
protection. The final rule is identical to the proposed rule, except 
that, as explained below, OSHA has added a note referencing subpart L 
for regulation of bricklaying work performed from scaffolds.
    The Mason Contractors Association of America (MCAA), International 
Union of Bricklayers and Allied Craftsmen; and the Laborers 
International Union of North America, (Ex. 2-95) commented in support 
of the proposed provision. The MCAA referred to the proposed provision 
as ``* * * the most reasonable, practical and economical and, above 
all, the safest method that can be devised for installing masonry 
products with the overhand method.'' OSHA concurs with the assessment 
of the MCAA with regard to this provision. In addition, the WMACSA (Ex. 
2-56) stated that overhand bricklaying should be prohibited as a 
practice, particularly when the work can be done from a scaffold. The 
MCISC (Ex. 2-140) commented that ``Guardrail systems for scaffolds 
should be spelled out in scaffold standards.'' OSHA agrees that it is 
appropriate for bricklaying performed from scaffolds to be regulated 
under subpart L, Scaffolds, rather than under subpart M and, 
accordingly, the Agency is adding a note to subpart L which so 
indicates. The MCISC also commented in support of the proposed 
provision, stating its belief that no fall protection was needed when 
bricklaying operations were conducted from inside a building, except 
when reaching more than 10 inches below the working surface. In 
response, it should be pointed out that one of the options in paragraph 
(b)(9)(i) is to allow overhand bricklaying workers reaching less than 
10 inches below the walking/working surface, to work in a controlled 
access zone which essentially allows the work to be done without fall 
protection, just as the MCISC is recommending for work conducted inside 
a building. This option is not a fall protection system per se, but 
rather a method which limits the exposure to the fall hazard to those 
workers actually involved in the bricklaying operation.
    Paragraph (b)(10) applies to employees performing roofing 
operations on low-slope roofs with unprotected sides and edges 6 feet 
(1.8 m) or more above lower levels. It requires that employers protect 
employees from fall hazards by either a guardrail system, safety net 
system, or personal fall arrest system. Or, employers must use a 
combination of warning line systems and guardrail systems, warning line 
systems and safety net systems, warning line systems and personal fall 
arrest system, or warning line systems and safety monitoring system. 
If, however, the roof is 50 feet (15.25 m) or less in width, the 
employer may protect employees by the use of a safety monitoring system 
alone.
    As with paragraph (b)(9), discussed above, the provisions of 
paragraph (b) which cover hoisting areas, holes, ramps and runways, and 
dangerous equipment apply notwithstanding the provisions of paragraph 
(b)(10). The rationale for these exceptions is the same as that 
provided in the discussion of paragraph (b)(9), above.
    The final provision differs substantially from the proposal. Under 
the proposed rule, employees performing ``built-up roofing operations 
(meaning the application of hot tar or bitumen) on low-pitched roofs'' 
were to be protected as required in existing Sec. 1926.500(g). 
Employees performing other roofing operations on low-slope roofs and 
exposed to falling 6 feet (1.8 m) or more to lower levels would have 
been covered by paragraph (b)(1) which applies, in general, to any 
walking/working surface with unprotected sides and edges 6 feet (1.8 m) 
above lower levels. The proposed paragraph was effectively identical 
with the provisions of existing Sec. 1926.500(g) for ``built-up'' 
roofing operations.
    OSHA promulgated existing Sec. 1926.500(g) because it recognized 
that the use of guardrail systems, safety net systems, and personal 
fall arrest systems could pose feasibility problems or greater hazard. 
OSHA discussed the reasons for this belief when it published the final 
rule for the built-up roofing standard (45 FR 75619). In particular, in 
the preamble to that final rule, OSHA stated the following:

    Guardrails are often used to provide fall protection and are 
required for open-sided floors and platforms by 1926.500(d)(1). 
However, although guardrails can be used during construction of a 
roof deck, they must be removed prior to the application of roof 
waterproofing membranes and related sheet metal work at the roof 
edge. According to a report by the engineering firm of Simpson, 
Gumpertz and Heger [Citation omitted], the reason guardrails must be 
removed is that, unless mounted on a parapet wall, guardrails are 
normally mounted on the roof deck and impede the application of the 
roof membrane. The use of freestanding guardrail systems as an 
alternative is limited since such guardrails must also be moved out 
of the way when the membrane is applied near roof edges and thus 
they are not a solution to the problem of providing fall protection. 
Other potential concerns include the increase in cost and time 
required to erect guardrails and the question of whether guardrails 
are needed when the work to be performed is not near the roof edge. 
These problems exist whether the work being done is a reroofing 
operation on an existing building or the application of a new roof 
on new construction. [45 FR 75619]

    In the 1980 final rule, OSHA also acknowledged that this same 
report, prepared for the National Roofing Contractors Association 
(NRCA), concluded that guardrails make orderly built-up roofing work 
impossible and do not offer the desired protection, since they must be 
removed prior to the completion of roof side and edge finishing work. 
The report also discussed the reasons other conventional guarding 
systems were not appropriate. A full discussion is contained 1980 
Federal Register notice. At that time, OSHA concluded as follows:

    OSHA believes that the difficulties with conventional guarding 
systems (referred to in the standard as ``motion-stopping-safety 
(MSS) systems'') during the performance of built-up roofing work, 
will be avoided by allowing the use of a warning line and/or safety 
monitoring system. OSHA explained that a warning line ``serves to 
warn and remind employees that they are approaching or working near 
a fall hazard by providing a direct physical contact with the 
employee. The contact attracts the employee's attention, enabling 
the employee to stop in time to avoid falling off the roof. The 
safety monitoring systems is a verbal warning system. OSHA describes 
the warning line systems with safety monitoring systems as an 
``alternative system of fall protection'' which are ``not intended 
to serve as positive fall restraints, but only as warning systems.''

    At the time of the proposed rule, OSHA relied on the information 
available from the 1980 rulemaking for built-up roofing work. Being 
unaware of any fall protection system that could be used in all cases 
and thus could eliminate the need for alternative systems such as the 
warning line system with safety monitoring system, OSHA proposed to 
continue its existing requirements but to seek public comment on other 
methods of protecting workers from fall hazards at the edge of low-
sloped roofs (flat roofs) during roofing work. In this regard, OSHA 
raised concerns about the height at which fall protection should be 
required for work on low-sloped roofs. Comments on this issue and other 
concerns regarding paragraph (b)(10) are discussed below.
    In addition, the existing provisions used the terms ``ground'' and 
``eaves,'' respectively, as the points between which the height 
criteria is to be measured. OSHA proposed, instead, to use the terms 
``lower levels'' and ``unprotected sides and edges.'' OSHA believed the 
proposed language change would eliminate confusion, since some roofs do 
not have eaves, and other roofs are greater distances above the ground 
than above the nearest lower level (penthouse roofs, for example).
    OSHA also proposed to permit built-up roofing work on low-pitched 
roofs with a fall distance less than 16 feet without the use of any of 
the fall protection systems required for other roofing work or required 
for higher work involving ``built-up'' roofing work. This, too, was 
consistent with the existing requirements in Sec. 1926.500(g), 
discussed above (see 45 FR 75618).
    Issue #11 requested comment, including cost and injury data, on 
lowering the fall protection threshold for built-up roofing from 16 
feet to 6 feet. OSHA stated that the 16-foot exemption for built-up 
roofing work was not appropriate and that a 6-foot threshold was both 
more appropriate and more consistent with the other provisions of 
subpart M. OSHA maintained that the contemplated change would not 
affect many built-up roofing employers because the option to use a 
safety monitoring system on low-pitched roofs with widths of less than 
50 feet would encompass nearly all roofs less than 16 feet above lower 
levels.
    OSHA received over 70 written comments in response to this issue, 
mostly from roofing contractors supporting views expressed by the 
National Roofing Contractors Association (NRCA). Virtually all of the 
commenters stated that roofs with widths of 50 feet or less were not 
necessarily also less than 16 feet above lower levels. Thus, the 
commenters felt that their compliance burdens would be greatly 
increased if the threshold height for providing fall protection was 
reduced to 6 feet. The commenters supported the existing language (16-
foot threshold) as the standard industry practice and as an appropriate 
response to fall hazards (Exs. 2-52, 2-58, 2-59, 2-61, 2-72, 2-90, 2-
91, 2-93, 2-111, 2-119, 2-122, 2-141, 2-143, 2-144, and 2-161).
    Also, the NRCA commenters favored continuation of the existing 
rules with regard to built-up roofing. These commenters stated that 
there was no need to protect workers from falling off unprotected sides 
and edges of low-slope roofs until the fall distance exceeded 16 feet. 
They also stated few injuries have resulted from such falls and that 
the cost of providing protection would exceed the benefits.
    For example, the American Roofing and Sheet Metal Co. (Ex. 2-86) 
commented that ``We have experienced no injuries from falls at roof 
perimeters and do not recognize this hazard to be significant compared 
to other hazards of roofing work.''
    One statistic frequently cited by NRCA commenters indicated that 
only one percent of losses were due to falls and most falls were 
experienced when workers fell through holes. However, the commenters 
did not explain what was meant by ``one percent of losses.''
    The H.B. Fishman & Co. (Ex. 2-70) commented, ``Again of the utmost 
importance is that holes in the deck, penetrations and other openings 
be properly protected. This is where the majority of injuries occur.''
    The Roofing Association of Long Island (Ex. 2-144) commented that 
``The experience gathered from other contractors as well as our own 
employees indicates that incidents of accidents as a result of falls 
from the perimeter of the roof are less frequent than the accidents 
resulting from falls through roof openings within the perimeter.''
    The Florida Service Roofing and Sheet Metal Company (Ex. 2-147) 
commented that ``Our experience, spanning 65 years, reveals that falls 
from the perimeter of roofs have been so minimal that they can be 
considered to have been virtually non-existent.'' OSHA notes that from 
the period of 1985-1989, 297 fatalities involving falls from roofs were 
investigated by OSHA (Ex. 30). While OSHA cannot state specifically if 
all of those falls occurred from the perimeter of roofs, it is 
reasonable to assume that the number of fatalities from the roof 
perimeter is high.
    Other commenters suggested that OSHA revise part of the proposed 
provision. Specifically, two commenters (Exs. 2-108 and 2-111) noted 
that the proposal implied that on roofs with widths of 50 feet or less, 
the use of a safety monitoring system was the only permitted system, 
rather than stating that it was an acceptable system. OSHA acknowledges 
that proposed paragraph (b)(10) could be misunderstood to allow only 
safety monitoring systems when a roof is 50 feet wide or less. The 
Agency has revised the proposed language to indicate clearly that on a 
roof 50 feet or less in width, the use of a safety monitoring system, 
without the warning line, is one of the measures allowed. OSHA allows 
the use of a safety monitoring system without the warning line on these 
narrow-width roofs because if warning lines were erected as prescribed 
in the standard, there would be little roof area remaining in which 
work could be performed.
    The ACCSH (Tr. 6/10/87; pp. 133-134) recommended that OSHA change 
the 16-foot threshold to 6 feet and that safety monitors be allowed 
only where employees are working on built-up roofs. Three other 
commenters also supported the 6-foot rule (Exs. 2-33, 2-46, and 2-99). 
NIOSH (Ex. 2-33) commented that allowing the 16 foot exemption was 
``inadequate'' and recommended that a maximum fall distance of 6 feet 
be set as appropriate for both low-slope roofs and steep roofs. They 
further suggested that the use of safety monitoring systems for flat 
and low-slope roofs might be an appropriate way of addressing the 
difference in hazards.
    While the Roofers Union (Ex. 2-99) supported the 16-foot threshold 
in the 1980 rulemaking for existing Sec. 1926.500(g), they opposed the 
continuation of that provision in proposed subpart M. Instead, they 
urged OSHA to ``promulgate a standard that will effectively protect 
roofers against the dangers from fall hazards which they face almost 
daily.'' They also questioned whether OSHA should continue to allow the 
use of warning line and safety monitoring systems to protect roofers 
working on low-slope roofs. The Roofers Union stated the following:

    In 1979 we endorsed OSHA's proposed rule to provide for a 
warning line on low-pitched roofs primarily because there were no 
standards covering the guarding of low- pitched roofs and something 
had to be done immediately * * *. We also stated that we would press 
for total perimeter protection if the warning line approach did not 
prevent injuries or deaths from falls off the roof edge.
    The standard (1926.500g) has been in effect now for over 6 years 
yet the industry continues to be plagued by the same safety 
problems--roof falls. Although there is no statistical evidence to 
demonstrate the effectiveness of the standard one way or the other, 
workmen's compensation rates for the roofing industry have risen 
significantly over the past 6 years. That indicates among other 
things that little is being done in the roofing industry to reduce 
the incidence of injuries and deaths.

    The Roofers Union also cited BLS data from a study on falls which 
showed that of 110 falls from roofs, half of these involved workers 
falling distances of less than 15 feet. Of these workers, over half 
suffered fractures to one or more parts of their body, over 40 percent 
suffered muscle sprains, strains or torn ligaments and 9 percent 
suffered a concussion.
    In conclusion, the Roofers Union stated, ``The data demonstrate 
that a significant number of serious injuries occur from falls of less 
than 16 feet. So it makes no sense to exclude a significant percentage 
of hazardous work from the OSHA standard. And, OSHA has indicated that 
these requirements would not place a significant economic burden on the 
roofing industry.'' The final recommendation was that total perimeter 
protection should be required because the warning line system was not 
effective.
    OSHA agrees with the Roofers Union that falls of less than 16 feet 
pose a significant hazard. OSHA also believes the injuries are related 
to the fall distance and the failure of contractors to take any fall 
protection measures, rather than the use of warning line systems. For 
this reason, OSHA will no longer permit workers exposed to falls 
between 6 feet and 16 feet to go unprotected from the fall hazard. OSHA 
believes the revised rule appropriately addresses the fall hazards on 
low-slope roofs and sets forth appropriate choices of fall protection, 
allowing roofing contractors some flexibility without sacrificing the 
safety of workers.
    OSHA agrees with the commenters who suggested that all employees 
engaged in roofing operations who are exposed to the hazard of falling 
6 feet (1.8 m) or more to lower levels should be protected in the same 
manner from fall hazards. OSHA also agrees with commenters who stated 
there is no need to distinguish between the application of hot and cold 
materials to determine the appropriate fall protection measures, hence 
the final provision will apply to all roofing operations on low-slope 
roofs and not just ``built-up'' roofing activities. OSHA notes that the 
criteria for warning line systems and safety monitoring systems are 
found in paragraphs (f) and (h) of Sec. 1926.502. Employers who use 
these systems must comply with all of the criteria and conditions for 
use that are specified.
    Paragraph (b)(11) (proposed as paragraph (c)) requires employees on 
roofs with slopes greater than 4 in 12 (i.e., 4 inches vertical to 12 
inches horizontal run) to be protected from falling when the roof has 
unprotected sides or edges more than 6 feet (1.8 m) above lower levels 
by the use of guardrail systems with toeboards, personal fall arrest 
systems, or safety net systems.
    The final provision differs from the proposal. The proposed 
provision addressed both falls through holes and falls from unprotected 
sides and edges of steep roofs. In the final rule, all falls through 
and into holes are covered by paragraph (b)(4). Therefore, there is no 
need for a separate provision dealing with holes on steep roofs. OSHA 
notes that the protective measures required for holes in paragraph 
(b)(4) are essentially the same as proposed for holes under the steep 
roof provision. Another change in the final rule is that OSHA is 
requiring toeboards to be used when guardrail systems are used to 
provide fall protection on steep roofs.
    The existing rules in subpart M do not specifically address fall 
protection requirements for steep roofs. Because of the lack of 
specific requirements, provisions outside subpart M have been utilized 
as the basis for citations for inadequate fall protection on steep 
roofs, including the following provisions: Sec. 1926.28(a) Personal 
protective equipment; Sec. 1926.104 Safety belts, lifelines, and 
lanyards; Sec. 1926.105 Safety nets; Sec. 1926.451(u)(3) Catch 
platforms; as well as the ``General Duty Clause'' (section 5(a)(1)) of 
the OSH Act). The final rule explicitly sets out the required fall 
protection systems for steep roofs.
    NIOSH (Ex. 2-33) supported the requirement to have fall protection 
on steep roofs when the fall distance to lower levels exceeds 6 feet 
(1.8 m). CAL/OSHA (Ex. 2-15) stated, ``The obvious hazard of the 
steepness of the roof, regardless of the eave height, should be 
addressed.'' They also suggested that ``On steep roofs of 8 in 12 or 
steeper slopes, where the fall down the roof slope itself exceeds 6 
feet (1.8 m),'' the use of roof jacks and body belt systems, safety net 
systems or positioning device systems would be appropriate. Paragraph 
(b)(11) of the final rule will permit employees to work on roof jacks 
provided the employee is protected from fall hazards by the use of 
guardrail systems with toeboards, safety net systems, or personal fall 
arrest systems. While roof jacks provide a foothold, which may reduce 
the possibility of falling, they cannot be used as a substitute for 
fall protection. The final rule will not permit employers to protect 
employees on roof jacks from fall hazards through the use of 
positioning devices systems because such systems will not protect 
affected employees from fall hazards.
    On the other hand OSHA observes, that because falls on steep roofs 
can result in workers and materials sliding down the slope, it would be 
appropriate to require the use of a toeboard as a standard practice 
when guardrail systems were chosen to provide fall protection. OSHA 
believes that omitting the toeboard would contribute to worker injuries 
since workers will not have any protective device to stop their sliding 
descent on the steep roof. OSHA notes that they could, then, slide 
right under the midrail and top rail of a conventional guardrail 
system.
    Paragraph (b)(12) is a new paragraph. OSHA is promulgating 
paragraph (b)(12), which was not part of the proposed rule, to set 
requirements for employers whose employees are exposed to fall hazards 
while erecting precast concrete members and related operations. Under 
paragraph (b)(12), employees erecting precast concrete members 6 feet 
(1.8 m) or more above a lower level must be protected from falling by 
guardrail systems, safety net systems, or personal fall arrest systems, 
unless the employer can demonstrate that such systems would be 
infeasible or would create a greater hazard at the site where the 
affected employees are working. In such a situation, an employer would 
be required to develop and implement a fall protection plan which 
conforms to Sec. 1926.502(k), discussed below.
    An exception is also allowed if another provision in paragraph (b) 
allows an alternative fall protection measure, such as covers over 
holes. Those alternative measures are also acceptable and do not need 
to be documented in a fall protection plan in order to be used.
    In the NPRM discussion of proposed paragraph (b)(2), Leading edges, 
(51 FR at 42721), OSHA indicated its recognition that it may be 
infeasible to protect workers performing precast concrete erection at 
the leading edge with guardrail systems, safety net systems, or 
personal fall arrest systems. Paragraph (b)(2) of the final rule 
provides that employers engaged in leading edge work (which can include 
precast concrete erection work) who demonstrate that it would be 
infeasible or would create a greater hazard to use conventional fall 
protection must develop and implement a fall protection plan which 
documents why they believe they cannot provide conventional fall 
protection and sets out the alternative fall protection measures that 
will be taken. In particular, the employer must establish a controlled 
access zone (29 CFR 1926.502(g)) and, at a minimum, implement a safety 
monitoring system (29 CFR 1926.502(h)) if no other alternative fall 
protection measure has been taken to protect leading edge workers. The 
provisions of paragraph (b)(12) are essentially the same as those of 
paragraph (b)(2), but extend beyond leading edge work and allow 
employers engaged in any work involving the erection of precast 
concrete to develop and implement a fall protection plan where they can 
demonstrate infeasibility or greater hazard with conventional fall 
protection systems. A full discussion of the meaning of 
``infeasibility'' and ``greater hazard'' was provided above along with 
the discussion of paragraph (b)(2) and applies here also.
    Paragraph (b)(12) has been added in response to comments regarding 
fall protection for precast concrete construction. Issue #2 of proposed 
subpart M asked:

    Are there areas or operations in addition to those already 
identified in proposed Sec. 1926.501, which have unique fall 
protection requirements not addressed by the proposed standards? 
Examples of such areas and operations might include carpenters 
erecting roof trusses during house construction; steel erectors 
working on other than tiered buildings . . . or connectors erecting 
wood, precast concrete, and structural members made of other 
materials. 51 FR at 42729.

    The Agency received several comments from the Precast/Prestressed 
Concrete Institute (PCI) (Exs. 2-44, 2-106 and 2-107) regarding the 
need for separate fall protection standards for workers engaged in 
precast concrete erection.
    Based on those comments, OSHA raised Issue M-2 in the January 26, 
1988, Notice of Hearing on subparts L, M, and X [53 FR 2048] to solicit 
testimony and other information on the concerns raised by PCI. 
Specifically, OSHA stated (53 FR 2054):

    The [Precast/]Prestressed Concrete Institute (PCI) (Ex. 2-44) 
has commented that fall protection for employees erecting precast 
concrete components is ``not appropriately covered by the proposed 
regulations'' in Subpart M, because, according to the PCI, concrete 
erectors, like steel erectors, need more freedom of movement than 
proposed Subpart M would permit. Therefore, the PCI suggested that 
OSHA revise proposed Subpart M so that precast concrete erection 
would be regulated under Subpart R, Steel Erection. At the August 4, 
1987, ACCSH meeting, a PCI representative reiterated the view that 
connectors of precast concrete members should be provided the same 
considerations as connectors of steel members saying [Tr. 212]: ``We 
feel that the erection procedures and exemptions for steel are 
basically the same as those for precast concrete * * * Basically, 
the fall protection of the steel connector, again, would be the same 
as that for the precast connector.'' The PCI subsequently submitted 
comments (Ex. 2-106 and 2-107) which requested that OSHA exempt 
concrete erectors from proposed leading edge protection requirements 
in Subpart M and that OSHA exempt hollow core slab erectors from 
perimeter protection provisions, except for those in proposed 
Sec. 1926.502(h), Safety monitoring systems.

    In response, PCI testified at the public hearing (Exs. 6A-9 and 9, 
and Tr. 53-82, March 22, 1988) and submitted post-hearing comments 
(Exs. 17 and 19), which reiterated the points made in its comments. 
OSHA subsequently received additional correspondence from PCI (Exs. 25-
1 and 25-2). In that correspondence, PCI (Ex. 25-1) stated that OSHA's 
``* * * lack of understanding of our unique erection problems will 
result in the promulgation of rules that will result in endless 
litigation and not serve the safety needs of the workers.'' In October 
1989, OSHA informed PCI (Ex. 25-3) that the rulemaking record had 
closed and that, in any event, the late comments simply repeated 
submissions that had already been included in the record.
    On February 12, 1990, PCI again wrote to OSHA (Ex. 25-4) 
reasserting that compliance with proposed subpart M was not appropriate 
to protect employees engaged in precast concrete erection. PCI again 
suggested that OSHA either regulate precast concrete under its own 
industry specific standard or under subpart R--Steel Erection, because 
either alternative would be more applicable than the generic subpart M 
standard. That submission also contained a more detailed discussion of 
precast concrete erection procedures, including fall protection 
procedures. OSHA responded (Ex. 25-5) that it would review the 
information presented in the letter and would reopen the record if 
significant issues were raised that had not previously been included in 
the record.
    On May 30, 1990, PCI again wrote to OSHA (Ex. 25-6) and expressed 
concern ``* * * relative to OSHA's work to revise the construction 
industry safety standards addressing fall protection in both 29 CFR 
1926 subparts M and R (Steel Erection).''
    On June 15, 1990, OSHA informed PCI that the information presented 
in their letters was under review and a decision on further action 
would be made at the completion of that review. OSHA determined that 
the supplemental submissions from PCI did provide new information which 
was relevant to a full consideration of the issues raised by subpart M. 
Accordingly, the Agency reopened the rulemaking record (57 FR 34656, 
August 5, 1992) for the limited purpose of entering the new information 
and to receive comments on it. The comment period ended on November 3, 
1992. The Agency reopened the record again (58 FR 16515, March 29, 
1993) to allow additional time for PCI and other interested parties to 
submit comments. That comment period ended on May 28, 1993. The 
comments supported the inclusion of a fall protection plan as an 
alternative where employers engaged in precast concrete construction 
work were able to demonstrate infeasibility or greater hazard with the 
use of conventional fall protection systems. A more thorough discussion 
of the comments can be found at Sec. 1926.502(k)--fall protection 
plans.
    Based on a careful review of the information submitted by PCI and 
other rulemaking participants, OSHA has determined that precast 
concrete construction entails unique work conditions which should be 
specifically addressed by subpart M. The new provision requires 
employers who can demonstrate that the use of conventional fall 
protection systems would be infeasible or would create a greater hazard 
to implement a fall protection plan that complies with Sec. 1926.502(k) 
of the final rule. OSHA is providing specific guidance in this notice 
regarding what constitutes ``infeasibility'' or a ``greater hazard'' 
(See Sec. 1926.501(b)(2)). OSHA encourages employers who believe that 
the use of a written fall protection plan is appropriate for their 
precast concrete construction operations to discuss the basis for their 
belief with local OSHA compliance staff. Additional information 
regarding the criteria for use of a fall protection plan is provided in 
the discussion of Sec. 1926.501(b)(2) of this section and in the 
discussion of the criteria for fall protection plans, Sec. 1926.502(k), 
as well as in Appendix E to subpart M--Model Fall Protection Plans. The 
Agency considers the implementation of a fall protection plan, 
outlining alternative fall protection measures, to be a ``last 
resort,'' allowed only where the other options for fall protection have 
been exhausted.
    Paragraph (b)(13), which also was not part of the proposed rule, 
requires that employers engaged in residential construction work 
protect employees from falls of 6 feet (l.8 m) or more to lower levels 
by the use of one of the three conventional fall protection systems 
unless such systems are infeasible or would create a greater hazard for 
affected employees. In those situations, OSHA requires the employer to 
develop and implement a Fall Protection Plan which meets the criteria 
of Sec. 1926.502(k), discussed in detail below.
    As with paragraph (b)(12) discussed above, if another provision in 
paragraph (b) allows an alternative fall protection measure, such as 
covers over holes, those alternatives measures are also acceptable and 
do not need to be documented in a fall protection plan in order to be 
used.
    OSHA is adding this new paragraph in response to comments received 
on the issues raised in the limited reopening of the rulemaking record 
[March 29, 1993; 58 FR 16515], regarding the ability of the residential 
construction industry to provide fall protection for certain employees. 
In that Notice, OSHA pointed out that Issue #2 of proposed subpart M 
(51 FR 42729) had asked if there were areas or operations which had 
unique fall protection needs not addressed by the proposed rule. OSHA 
specifically mentioned carpenters erecting roof trusses during house 
construction as a possible example. OSHA raised these issues in a 
reopening notice because the Agency had received a late comment in 
December 1992 from Ryland (Ex. 27-15) requesting that OSHA reopen the 
record for subpart M to allow input regarding the residential 
construction industry's ability to provide fall protection for 
employees erecting roof trusses and installing exterior wall panels. 
Ryland stated that there were no feasible means of fall protection for 
employees erecting roof trusses and installing exterior wall panels. 
The Ryland letter also explained the reasons they believed the proposed 
and existing fall protection requirements were infeasible or that 
compliance would create a greater hazard that non-compliance.
    In the reopening notice, OSHA raised the possibility of allowing 
employers to develop and implement a fall protection plan in those 
situations where employers were able to demonstrate that it was 
infeasible or would create a greater hazard to use conventional fall 
protection systems. OSHA also requested information on the use of 
controlled access zones, warning line systems and safety monitoring 
systems as part of a fall protection plan. OSHA also asked what methods 
of providing fall protection were being used by builders to protect 
employees who are installing walls and erecting roof trusses; what 
contractors were using for anchorage points on roofs; and to what 
extent it was feasible to protect employees with conventional fall 
protection systems while erecting trusses and installing wall panels.
    A number of home builders responded that they were pleased that 
OSHA had recognized the need to take the residential construction 
industry (Ex. 27-23, 27-24, 27-26, 27-27, 27-33, and 27-34) into 
account when revising subpart M. These commenters noted that the 
failure of various OSHA standards to distinguish between the 
residential/light commercial sector of the industry and the heavy 
commercial/industrial sectors had forced the residential sector into 
noncompliance. Ryland and the National Association of Home Builders 
(Exs. 27-23, 27-27, 27-33, 27-34) commented that they:

* * *  would like to urge OSHA to establish in Subpart M a separate 
section applying to the residential/light commercial sector, even if 
[it] means repeating requirements from other sections of Subpart M 
that apply to all construction. We believe this action is imperative 
if OSHA is intent on improving safety in the residential/light 
commercial sector of the industry.

    The Home Builders Association of Maryland (HBAM) and Hallmark 
Builders (Exs. 27-24 and 27-26) supported the above position. Both 
commenters stated the following:

    Currently, the standards for enforcement of these industries are 
the very same used by OSHA to safeguard the heavy commercial and 
industrial sectors of the construction industry. Unfortunately, many 
practices that may be feasible within these heavier industries 
become impractical and sometime impossible within residential and 
light commercial construction.

    Finally, they noted that a larger number of employees would benefit 
from increased protection through safer workplaces if separate 
standards were issued because they would be easily implemented and 
enforced and more widely accepted. This they noted, ``* * * would 
further the goals of both OSHA and the employer.
    The Home Builders Association of Denver (Ex. 27-39) also commented 
that the existing standards are written for general construction work, 
and that a new section is needed for residential construction only. 
They also noted that a majority of residential builders also perform 
some amount of light commercial work and the two types of construction 
should be categorized as ``light construction.''
    The Home Builders Association of Denver also provided some 
information regarding the measures it believes an employer can take 
when the employer determines that conventional fall protection cannot 
be used. OSHA notes that the comment provides information which could 
be useful once an employer established that a fall protection plan, 
tailored specifically for the home being built, was appropriate. 
However, the comment does not address the more important issue: How 
does the employer establish, in the first place why none of the three 
conventional systems can be used?
    While the Agency encourages creative solutions to fall protection 
problems, OSHA does not expect employers (home builders) to pursue 
measures which would make their work unprofitable. For example, OSHA 
expects that there will be circumstances where a home builder will find 
it to be cost-effective to rent a crane for the purpose of hoisting 
roof trusses, particularly when several roofs can be set in a single 
day. Also, OSHA is aware, as documented in this final rule, that there 
are a number of devices readily available for use as attachment points 
for fall arrest equipment and that employers must be able to document 
why the use of such equipment is infeasible or creates a greater hazard 
to meet the criteria for using a fall protection plan.
    On the other hand, the Agency believes it would be unreasonable to 
expect the home builder to rent a crane when the home site is difficult 
to access (terrain or remote location, such as in the mountains) or 
when the home builder has only a single roof to raise. In addition, 
OSHA does not expect home builders to erect scaffolds around the entire 
perimeter of a house, or to take other extremely burdensome measures 
such as erecting separate structures (telephone poles, e.g.) and 
stringing a lifeline to use as an attachment point for personal fall 
arrest equipment. These measures are infeasible.
    In the course of this rulemaking, only two specific tasks have been 
identified by OSHA as potentially creating an infeasible or greater 
hazard situation. One is bracing roof trusses and the other is erecting 
panelized walls. OSHA believes that, in general, it is feasible to set 
trusses from ladders, scaffolds, or other elevated work platforms 
provided there is sufficient space to set up ladders, scaffolds or 
elevated platforms. When space makes it impossible to use such 
measures, the employer will have to develop and implement a fall 
protection plan meeting the criteria of paragraph (k) of Sec. 1926.502.
    The South Eastern Wyoming Home Builders Association (SEWHBA) (Ex. 
27-35) stated ``The feasibility of added protection for workers 
installing roof trusses and/or above grade wall panels is ineffective 
and possibly more hazardous than the current systems used...'' The best 
protection of these workers would be in training for recognition of 
such hazards and proper caution. They also stated that ``[a] `Fall 
Protection Plan' is the most effective way to provide protection. 
Warning lines would at least advise other crews of activity above, 
allowing proper caution in approaching the site.'' The commenter 
indicated that it didn't believe control zones were feasible. The 
SEWHBA also noted that fall protection plans for residential 
construction should be comparable to those in commercial construction 
noting that ``Residential construction is essentially the same in most 
cases, except possibly ``high rise'' type activities.
    David Welty of Welty Construction Co. Inc. (Ex. 27-31) stated that 
it was ``too dangerous'' to set rafters and trusses while walking on 
the top of 2 x 4 walls and described how he installed rafters and roof 
trusses working off ladders from inside the upper floors. Welty also 
commented there was an added risk to erecting guardrail systems, 
scaffolding, etc. and that ``for erecting roof trusses, we believe it 
is sufficient to require workers to work from ladders inside the 
walls'' citing feasibility problems with conventional fall protection 
systems. Finally, Welty noted that ``fall protection plans, warning 
lines, and monitoring systems are probably not effective in enhancing 
safety.''
    Another builder, Schuck & Sons Construction Company (Ex. 27-37) 
stated ``[p]rotecting employees from falls has been a real dilemma in 
the residential framing industry.'' He believes that a greater hazard 
occurs while employees are installing fall protection systems and the 
lack of solid anchorage points presents compliance problems.
    Arguing against any separate treatment for residential construction 
was the United Brotherhood of Carpenters, (Ex. 27-25) who commented 
that there was little fall protection being provided to workers in the 
residential industry and that ``[C]onventional fall protection measures 
are feasible.'' They also commented that when erecting roof trusses or 
installing exterior wall panels, ``It would be safer to work from a 
scaffold rather than a ladder because of the larger area of work 
surface. Working from a scaffold would be feasible'' and that ``Present 
technology and fall arrest equipment is available which would make it 
possible to protect employees installing exterior wall panels.'' 
Finally, the Carpenters Union noted:

    The fall protection safety requirements for residential 
construction should be the same as those for commercial 
construction. The fact that residential construction has gone 
unregulated and unenforced for so long is no reason to create a 
``double safety standard.'' The hazards in residential construction 
are every bit as real as those in commercial construction.

    OSHA encourages employers to require their employees to work from 
ladders, scaffolds and other platforms rather than for example, walking 
the top plate when setting or bracing trusses. Employees who are 
required to be on the top plate to work must be protected from fall 
hazards (falls of 6 feet or more to the lower level) by one of the 
three conventional fall protection systems unless they are covered by a 
fall protection plan which specifies other alternative measures. OSHA 
reminds employers that subpart M does not require fall protection for 
employees working on ladders and scaffolds. (See subpart L for specific 
requirements for fall protection on scaffolds and subpart X for 
specific requirements for fall protection on fixed ladders).
    NIOSH (Ex. 27-20) commented that they had performed several 
analyses and compared the proportion of workers' compensation claims in 
the residential building construction industry that involve falls from 
elevations to those in other sectors of the construction industry. The 
findings were that

* * * injured residential construction workers had at least as high 
a proportion of their injuries due to falls from elevations as all 
other construction workers. They also found that injured residential 
construction workers had at least as high a proportion of their 
injuries due to falls from elevations as nonresidential construction 
workers.

Therefore, based on these analysis, NIOSH stated that fall protection 
requirements for employees in residential construction ``should not be 
less stringent than fall protection requirements for employees in other 
construction categories.''
    OSHA also received comments from fall protection equipment 
manufacturers and consultants. For example, Sinco (Ex. 27-30) commented 
that they have developed many new products, notably fall protection for 
roofers, that are readily available now for use in residential 
construction. They also noted that many forward thinking contractors 
are developing fall prevention programs, purchasing fall protection 
systems, and when appropriate, altering means and methods for 
accommodating use of fall protection equipment. Sinco also commented on 
the existing anchorage requirement of 5,400 pounds, noting that it does 
present unique problems in compliance on wood frame buildings. However, 
engineered systems using OSHA fall arrest requirements in the powered 
platform rule, Sec. 1910.66, Appendix C, incorporating retracting 
lifelines, etc. would enable contractors to provide fall protection 
with secure anchor points. Sinco also made the following statements 
pertinent to this rulemaking:

    Most residential builders have no plan for fall protection, 
subsequently they have no fall protection equipment, and most remain 
unenlightened about the fall protection systems that are readily 
available. Today, safety systems are available that will enable 
residential builders to substantially reduce their employee exposure 
to fall hazards during framing and roofing operations.

* * * manufacturers have developed engineered fall protection 
systems that can be secured to anchorages capable of supporting 
twice the potential impact load of an employee's fall. Anchor points 
can vary, some examples are ridge beams, rafters, trusses, and floor 
joints. With proper planning, a minimum of bracing and sheathing can 
develop the structural integrity necessary to support these types of 
anchorages. Scaffolding can be erected with the building interior 
and serve as a work platform during truss bracing operations. New 
products, such as the UNITRAC Truss Walk, provide an interior work 
platform as well as meeting a contractor's fall protection needs 
during truss installation and bracing.

    In addition, Sinco presented information about other products they 
have available now for use during wall installation, truss 
installation, sheathing, and the application of roofing materials. 
Sinco also commented that the use of control zones, warning lines, and 
safety monitors should be an option extended through OSHA as a SITE 
SPECIFIC exemption only and that contractors should have to demonstrate 
by individual tasks that conventional fall protection measures are not 
appropriate at specific project sites. While Sinco stated ``[t]he 
agency should require employers to provide fall protection for all 
facets of residential construction where fall hazards exist,'' it also 
stated that if the employer can demonstrate infeasibility or greater 
hazard, the Agency should grant an exemption on a case by case basis.
    Griphoist (Ex. 27-40) suggested that OSHA require anchorages used 
with personal fall arrest systems in residential construction be 
required to withstand a load of 3,600 pounds, with employees wearing 
body harnesses, rather than 5,400 pounds. The commenter noted that the 
suggested figure is twice the potential impact load allowed by the ANSI 
standard, ANSI Z359.1-1992, of 1,800 pounds.
    Dynamic Scientific Controls (Ex. 27-42) stated that ``It is my 
opinion that conventional fall protection can be applied to residential 
roof construction, including truss erection, sheeting and roofing.''
    OSHA also received comment from Gary Sipe, President of Peakrider 
(Ex. 27-29), who commented on a new product currently being introduced 
to the market called ``Peakrider.'' The product was designed to provide 
a measure of safety for employees setting prefabricated wood trusses 
for residential and small professional office construction. Mr. Sipe 
also noted that the product is new and not many construction firms know 
of its existence. Mr. Sipe also provided information on other products 
designed for use in residential construction to reduce the exposure of 
employees to fall hazards.
    Finally, OSHA received comment from Douglas Browning (Ex. 27-32) 
who provided information on a scaffold system that has been field-
tested for use in residential construction to reduce the exposure of 
employees to fall hazards during roof truss installation.
    OSHA recognizes that some employers engaged in erecting and bracing 
roof trusses, because of their building methods, may find that it is 
infeasible or would create a greater hazard to provide and use 
conventional fall protection systems to protect employees performing 
these tasks. In these situations, OSHA suggests that employers review 
their building methods to determine if a change in work procedures 
could eliminate or reduce fall hazards. If the employer can demonstrate 
either infeasibility or greater hazard, applying the criteria discussed 
above and in relation to paragraph (b)(2) of this section, the employer 
must implement alternative safe work practices, such as requiring work 
to be performed from ladders, scaffolds or other types of work 
platforms and prohibiting the practice of standing on the top plate of 
the walls to set (secure) roof trusses to the walls. OSHA is also aware 
that some builders assemble the roof system on the ground, either 
partially or entirely, and then lift it into place. OSHA would expect 
any fall protection plans developed under this paragraph to explain why 
such measures could not be implemented when other builders find them to 
be feasible alternatives. The evidence indicates that many home 
builders have yet to focus their attention on alternative safe work 
practices that can be implemented in those areas where concerns have 
been raised.
    OSHA believes, based on the rulemaking record, that employers can 
protect their employees from fall hazards with conventional fall 
protection systems in virtually all situations involving residential 
construction work. OSHA is being responsive to the concerns raised by 
home builders, in particular, with support from some fall protection 
equipment manufacturers, that there may be some limited situations 
where the use of conventional fall protection systems is infeasible or 
would create a greater hazard than would exist if such systems were not 
used. It is for this reason that OSHA has established a regulatory 
mechanism (fall protection plan) through which an employer who 
satisfies the pertinent criteria must implement a fall protection plan 
instead of providing conventional fall protection.
    OSHA encourages home builders in their efforts to improve the 
safety and health of their workers. While many of the home builders' 
comments urged OSHA to recognize the ``inherent differences,'' between 
``light'' construction and ``heavy'' construction, the evidence 
submitted was insufficient to convince OSHA that the methods of 
protecting workers from fall hazards associated with light construction 
and heavy commercial construction differed sufficiently to require 
different rules. OSHA is intent on improving safety in the residential 
sector of the construction industry and views the promulgation of 
Sec. 1925.501(b)(13) as a concrete step towards increased safety for 
workers in this part of the construction industry.
    Based on a careful review of the information submitted by home 
builders and other rulemaking participants, OSHA has determined that 
residential construction work entails unique work conditions which 
should be specifically addressed by subpart M. Therefore, OSHA is 
promulgating a new Sec. 1926.501(b)(13), which specifically addresses 
this type of construction work. The new provision requires employers to 
use conventional fall protection systems unless they can demonstrate 
that the use of conventional fall protection systems would be 
infeasible (impossible to get the work done or technologically 
impossible) or would create a greater hazard and then they must 
implement a fall protection plan that complies with Sec. 1926.502(k) of 
the final rule.
    Additionally, Sec. 1926.502(k)(5) requires that the fall protection 
plan document the basis for the determination that fall protection 
cannot be used. The Agency considers the implementation of a fall 
protection plan, outlining alternative fall protection measures, to be 
a ``last resort,'' allowed only where the other options for fall 
protection have been exhausted. As noted above, OSHA is providing 
specific guidance in this notice regarding what constitutes 
``infeasibility'' or a ``greater hazard'' (See discussion at 
Sec. 1926.501(b)(2)).
    OSHA has included a sample fall protection plan for residential 
construction in non-mandatory Appendix E--Model Fall Protection Plans 
to provide guidance to home builders.
    Paragraph (b)(14) of the final rule (proposed Sec. 19265.501(d)) 
requires protection for employees who are exposed to the hazard of 
falling out or through wall openings. The final rule consolidates and 
clarifies requirements in existing Sec. 1926.500(c) (1) and (3). Under 
the final rule, wall openings (defined as openings 30 inches or more 
high and 18 inches or more wide, which have a bottom edge to lower 
level fall distance of 6 feet or more on the side away from the 
employees, and a bottom edge to walking/working surface height of less 
than 39 inches on the side facing the employees), must be equipped with 
a guardrail system, safety net system, or personal fall arrest system. 
OSHA believes the most practical method of compliance is the guardrail 
system because it provides protection at all times and for all 
employees who may have exposure at the wall opening. However, OSHA 
recognizes that there may be cases where employers may desire to use 
safety net systems or personal fall arrest systems, which also will 
provide an appropriate level of protection. For that reason, the 
provision has been revised to permit the use of these other systems.
    The final rule is similar to the proposed rule, except for the 
change discussed above and the existing rule in Sec. 1926.500(c)(1) 
requires such protection to be provided when the fall distance exceeds 
4 feet, and when the near side height is less than 36 inches. OSHA 
proposed to change the existing rule to make it compatible with the 6-
foot rule of other provisions in Sec. 1926.501, the minimum height 
requirements for guardrail systems of Sec. 1926.502(b)(1), and the 
definition of ``unprotected sides and edges.''
    The SSFI (Ex. 2-89) recommended that employees on elevated work 
platforms adjacent to a floor or wall opening should be protected by a 
fall protection system regardless of the height of the platform. OSHA 
observes that proposed subpart L sets forth requirements for employees 
working on scaffolds [elevated work platforms] and that the final rule 
for subpart L will address this issue.
    New paragraph (b)(15) is a ``catch all'' provision intended to 
clarify the overall thrust of paragraph (b). It sets forth clearly that 
all employees exposed to falls of 6 feet (1.8 m) or more to lower 
levels must be protected by a guardrail system, safety net system, or 
personal fall arrest system except where otherwise provided by 
Sec. 1926.501(b) or by fall protection standards in other subparts of 
part 1926. The Agency has determined that this provision will 
facilitate compliance for employers who do not fit any of the specific 
categories set by Sec. 1926.501(b).
    Paragraph (c)--Protection from falling objects. This provision, 
proposed as Sec. 1926.501(e), requires employers to protect employees 
from falling objects by either:
    (1) Using toeboards, screens, or guardrail systems;
    (2) Erecting a canopy structure and placing potential fall objects 
away from edges; or,
    (3) Barricading the area to which objects could fall, prohibiting 
employees from entering that area, and placing potential fall objects 
away from the edges.
    This requirement differs from the proposed requirement and the 
existing requirements. The existing requirements in Sec. 1926.500(b) 
(1), (2), (3)(ii), and (8) and Sec. 1926.500(d)(2) require toeboards to 
be erected around floor, roof, ramps, and platform holes and openings 
regardless of whether or not employees are working below. OSHA proposed 
to revise the existing requirement to require that, in addition to 
wearing hard hats (Sec. 1926.100), employees would have had to be 
protected from falling objects by one of a series of measures, which 
included the following:

--installing toeboards, screens or guardrail systems to keep objects 
from falling from above;
--erecting canopy structures;
--marking the area with signs; or barricading the area to prohibit 
employees from entering the area; or,
--placing objects away from edges from which they might fall.

    In the proposal, OSHA stated that it believed the alternatives 
listed for providing falling object protection were more feasible than 
the existing requirements, which only specified the use of toeboards or 
screens. OSHA also noted that it did not specify a distance away from 
the edge that objects should be kept, as the distance varies according 
to the shape of the object. For example, the preamble to the proposal 
stated that round objects such as rolls of roofing felt would require 
more distance than a stack of flat shingles, and that the distance also 
depends on the height of the object or pile of objects. Both in the 
discussion of proposed Sec. 1926.501(e) and in Issue #12, OSHA 
requested public input regarding the proposed use of signs as a means 
of keeping employees out of areas where they might be exposed to 
falling objects. In addition, OSHA requested input on the criteria for 
falling object protection in Issue #8, discussed below.
    In response, the States of California (CAL/OSHA) and Maryland 
(MOSH) (Exs. 2-15 and 2-31) remarked that signs were not acceptable 
substitutes for barricades to prevent employee exposure to the falling 
object hazards. Additionally, the ACCSH (Tr. 6/10/87; pp. 113-128) 
recommended to OSHA that all of the listed alternatives should be 
required with no option, except that employers could choose between a 
canopy structure and a barricaded area as part of their protective 
measures. In short, their recommendation was that toeboards, screens 
and guardrails be erected; and that objects be kept back from the edge; 
and that employers either erect a canopy and signs or barricades.
    OSHA has not incorporated the suggestion of the ACCSH because the 
record does not support requiring employers to take all of the 
recommended precautions. OSHA believes employees will be afforded an 
appropriate level of safety if the employer prevents objects from 
falling from above, or protects employees from objects that have fallen 
in spite of efforts to keep them from falling.
    Many other commenters (Exs. 2-19, 2-20, 2-45, 2-46, and 2-99) also 
objected to the use of signs as an option for protecting employees. 
Other commenters (Exs. 2-20, 2-46 and 2-89) thought that signs could be 
useful in conjunction with more positive protection like barricades. 
The AGC (Ex. 2-16, 2-47 and 2-92) supported the proposed provision, 
noting that alternative methods provide for employer flexibility. The 
AGC also noted that signs had been used in the past successfully, 
depending on the type of exposure and the particular situation. The 
SSFI (Ex. 2-89) recommended that the use of signs be acceptable where 
no other fall protection measures could be used.
    OSHA has determined, based on the record, that signs are not an 
appropriate alternative to barricades in the situations discussed in 
Issue #12. OSHA recognizes that signs can be useful when used in 
conjunction with other measures, such as barricades, to warn employees 
of the hazard, but believes that signs, alone, provide inadequate 
protection from falling objects. Accordingly, the Agency has deleted 
the option of using signs as a means of complying with 
Sec. 1926.501(c).
Sec. 1926.502--Fall Protection Systems Criteria and Practices
    This section specifies the criteria for measures required by 
Sec. 1926.501 and by other subparts in part 1926 where specific fall 
protection systems criteria and practice are not provided. The 
following discussion highlights changes from or additions to the 
proposed and existing standards. Provisions that are essentially 
unchanged from the proposal, especially where they did not elicit 
comments, are not discussed.
    OSHA received one comment directed at Sec. 1926.502 in its 
entirety. The SSFI (Ex. 2-89) stated ``language appearing within this 
section seems to be inconsistent with comparable paragraphs of subpart 
L.'' The commenter recommended that OSHA revise subpart M to be 
compatible with subpart L. Rather than comment on the general statement 
made by SSFI, OSHA will respond to their concerns in its discussion of 
the individual provisions where SSFI has stated that an inconsistency 
exists.
    Paragraph (a)--General. This paragraph requires that all fall 
protection conform to the criteria set in paragraph (b) for the 
particular system being used and that all fall protection equipment be 
provided and installed before employees begin any other work on or from 
the surface on which they will be protected. To be fully effective, 
fall protection must be in place at the earliest possible time.
    There were two comments on paragraph (a). PCI (Ex. 2-44) commented 
on the need for employees to create the surface before protection 
systems can be provided and installed. NIOSH (Ex. 2-33) commented that 
``OSHA should clearly state that the first worker allowed upon a roof 
or leading edge is designated as the competent person under the 
requirements of the safety monitoring systems if that is, in fact, 
OSHA's intent.''
    OSHA's intent is that fall protection systems be in place at the 
earliest possible time when there is potential exposure to fall 
hazards. OSHA recognizes that there will be situations where it is 
infeasible to install and use fall protection because the working 
surface has not yet been created and there is no surface upon which to 
place guardrail systems, install safety nets, or anchor personal fall 
arrest systems. OSHA has discussed under Secs. 1926.501 (b)(2), 
(b)(12), and (b)(13), for example, the alternative measures (fall 
protection plan) that would be required in a situation where such 
infeasibility or greater hazard situations arise. With regard to the 
concern expressed by NIOSH, OSHA has determined that, while it would 
not be appropriate to mandate that the first person allowed on a roof 
or leading edge necessarily be designated as the competent person for a 
safety monitoring system, it is appropriate to provide that no employee 
may begin any work until the fall protection systems are provided and 
installed that this would include having the competent person in 
position at the assigned work area and assuming the duties of the 
safety monitor when such monitoring systems are required as part of a 
fall protection measure.
    Paragraph (b)--Guardrail systems. This paragraph sets the criteria 
for guardrail systems. Paragraph (b)(1) specifies that the top edge of 
guardrail systems shall be 42 inches, plus or minus 3 inches, above the 
walking/working surface except when conditions warrant, the height of 
the top edge of the top rail may exceed the 45-inch limit. Paragraph 
(b)(1) also contains a note to remind employers that where employees 
are using stilts the height of the top rail must be increased a height 
equal to the height of the stilts which in effect serve as the walking/
working surface. This note has been added in response to comments 
received on Issue L-4 of the hearing notice published on January 26, 
1988, in which OSHA asked questions about fall protection for workers 
on elevated platforms such as stilts. More detailed discussion of the 
issue will be found in the final rule on scaffolds to be published 
later.
    The final rule is slightly different from the proposed rule in that 
OSHA is allowing the employer additional flexibility with regard to the 
height of the top edge of the top rail of the guardrail system. This 
change has been made because OSHA is aware that there will be 
situations where work conditions necessitate erecting the guardrail so 
that the top edge height is greater than 45 inches. The requirement is 
also consistent with the existing rule in Sec. 1926.500(f)(l), which 
requires that the guardrail system be ``approximately 42 inches from 
upper surface of top rail to floor, platform, runway, or ramp level.'' 
OSHA proposed to revise the existing rule by deleting the term 
``approximately'' and by having the height requirement of 42 inches, 
plus or minus 3 inches, apply to all walking/working surfaces.
    The general, introductory text of paragraph (b)(2) requires 
midrails, screens, mesh, intermediate vertical members (i.e., 
balusters), solid panels, or equivalent structural members to be 
installed between the top edge of the system and the walking/working 
surface when there is no wall or parapet wall at least 21 inches high. 
This is identical to the proposed requirement and is essentially the 
same as the existing requirement Sec. 1926.500(f)(l)(vi)(c).
    Paragraphs (b)(2) (i) through (iv) set requirements which apply 
specifically to midrails; screens and mesh; intermediate members; and 
other structural members respectively.
    Paragraph (b)(2)(i) specifies that when midrails are used to comply 
with paragraph (b)(2), they must be installed midway between the top 
edge of the guardrail system and the walking/working level. This 
requirement is the same as the requirements in both the proposed rule 
and in the existing rule at 1926.500(f)(l).
    Paragraphs (b)(2) (ii), (iii) and (iv) address the proper placement 
of screens, mesh, intermediate vertical members, and other structural 
members when they are used in lieu of midrails in the guardrail system. 
These provisions are essentially the same as the proposed provisions. 
The existing rule does not contain any requirements addressing the 
placement of structural members used in lieu of midrails.
    NIOSH (Ex. 2-33) commented that the criteria in proposed 
Sec. 1926.502(b)(1) [promulgated as Sec. 1926.501(b)(14)] for the 
placement of a top rail of a guardrail system (42 inches) and the 
criteria in proposed Sec. 1926.502(b)(2)(iii) for placement of 
intermediate members (no more than 19 inches apart) were inconsistent 
with the dimensions of a wall opening which OSHA defined in proposed 
Sec. 1926.501(d) as an opening in a wall or partition that was 30 
inches or more high and 18 inches or more wide.
    OSHA notes that under Sec. 1926.501(b)(14) employees exposed to 
falling 6 feet (1.8 m) or more through wall openings (where the inside 
bottom edge of the wall opening is less than 39 inches above the 
walking/working surface) must be protected by a guardrail system. NIOSH 
stated its belief that the dimensions in the wall opening provision 
should be made consistent with the dimensions of openings in 
guardrails. OSHA believes that Secs. 1926.501(b)(14) of the final rule 
and 1926.502 (b)(1) and (b)(2) (iii) and (iv) address different 
situations and, therefore, need not be reconciled. In particular, 
falling through window and door openings in walls presents a different 
hazard than falling through the openings in guardrail systems. 
Accordingly, OSHA has not made the suggested change.
    SSFI (Ex. 2-89) recommended that proposed paragraph (b)(2)(i) be 
changed to require the installation of midrails ``approximately'' 
midway between the top edge of the guardrail systems and the walking/
working level.'' The Agency notes that the use of terms such as 
``approximately'' have caused uncertainty among employer who have 
expressed their desire for OSHA to be clear in its rules. OSHA has 
determined that employers need clear direction when attempting to 
comply with paragraph (b)(2). Therefore, the Agency has not made the 
suggested revision.
    Paragraph (b)(3) requires guardrail systems to be capable of 
withstanding a 200-pound force applied within 2 inches of the top edge 
in an outward or downward direction. Paragraph (b)(4) requires that 
when the 200 pound load is applied in a downward direction, the top 
edge of the guardrail shall not deflect to a height less than 39 inches 
above the walking/working level. These are the same as the proposed 
requirements and essentially the same as the existing requirement in 
Sec. 1926.500(f)(1)(vi)(b), except that in paragraph (b)(4) the 
existing language, ``with a minimum deflection,'' has been changed to 
read ``when the 200 pound test load is applied in a downward direction, 
the top edge of the guardrail shall not deflect to a height less than 
39 inches above the walking/working surface.'' Deflection is specified 
for the top edge because that is the point an employee is most likely 
to fall against and it must be high enough, at all times, to prevent 
the employee from falling over the top rail.
    There were four comments on the proposed provisions. Seedorf 
Masonry (Ex. 2-153) commented, ``Paragraph 3 says that the guardrail 
must withstand at least 200 lbs. with apparently no more deflection 
than 2 inches.'' OSHA notes that the 2-inch figure in paragraph (b)(3) 
specifies where the force should be applied above the top rail to test 
the strength of the guardrail system. Paragraph (b)(4) sets the limit 
on top rail deflection--the top rail cannot deflect below 39 inches, 
which would be 3 inches if the top rail was at the 42 inch height when 
the load was applied or 5 inches if the top rail were at 45 inches.
    Regarding proposed paragraph (b)(3), the SSFI (Ex. 2-89) commented 
that proposed subpart L did not require force to be applied ``within 2-
inches'' and expressed concern with regard to the perceived 
inconsistency with subpart L. SSFI also commented that in paragraph 
(b)(4) there is a difference for the height of the top rails of 
guardrail systems between subparts L and M. OSHA, in turn, observes 
that the criteria for guardrails on scaffolds are explicitly excluded 
from the scope of subpart M (See Sec. 1926.500(a)(3)(i)), because OSHA 
recognizes that the performance requirements for guardrails on 
scaffolds will differ from those for employees on other walking/working 
surfaces.
    Two commenters (Ex. 2-104 and 2-151) stated that proposed paragraph 
(b)(4) was unworkable because a guardrail system capable of sustaining 
a 200-pound load with a maximum 3-inch deflection would require 
enormous strength. The commenters suggested that OSHA specify a 50-
pound load and 5-inches of deflection, but did not indicate any reason 
other than the inability to comply. The Agency believes that it is both 
necessary and feasible to engineer a guardrail system so that the top 
edge of the top rail does not deflect below 39 inches to protect 
employees from going over the rail and that a 200-pound test load is 
appropriate. Therefore, the Agency has not made the suggested change.
    As noted above, subpart M does not set the performance requirements 
for guardrails on scaffolds because the Agency has recognized that the 
two subparts address different concerns. Therefore, the provisions do 
not need to be consistent.
    Paragraph (b)(5), which is identical to the proposed paragraph, 
provides that midrails, screens, mesh, intermediate vertical members, 
solid panels, and equivalent structural members shall be capable of 
withstanding, without failure, a force of at least 150 pounds, applied 
in any downward or outward direction at any point along the midrail or 
other member. OSHA chose the 150-pound test strength because the Agency 
has determined that such members need not satisfy the 200-pound 
strength test set for top rails to provide the necessary protection. 
OSHA also determined that a limit on deflection was not needed for 
midrails and other members to protect employees appropriately. OSHA 
received no comments on this provision.
    Paragraph (b)(6) requires that guardrail systems be smooth surfaced 
to prevent employee injury due to lacerations or tripping caused by 
snagged clothing. The provision is based on the existing rule in 
1926.500(f)(1)(vi)(a). The proposed revision was effectively identical 
to the final rule, except that the proposed paragraph ended with the 
phrase, ``which could cause an employee to fall.''
    OSHA received two comments on this provision. CAL/OSHA (Ex. 2-15) 
suggested that OSHA remove the words ``which could cause employees to 
fall.'' OSHA had used those words to explain why guardrail systems 
should be surfaced to prevent snagging of clothing. However, California 
interpreted the phrase to be a ``qualifier,'' meaning that if the 
snagging of clothing would not result in a fall, employers did not have 
to take any action to eliminate the potential for snagging.
    OSHA agrees that the phrase should be removed in the final rule. It 
was not OSHA's intent to limit protection to those situations where 
such snagging would actually result in a fall. OSHA realizes that other 
hazards, such as exposure to falling objects, could arise if an 
employee's clothing snagged on a guardrail surface.
    The SSFI (Ex. 2-89) commented that this provision is unrealistic 
and would prove to be extremely costly. They recommended that the 
provision be eliminated. OSHA disagrees with the SSFI. As noted above, 
paragraph (b)(6) is essentially the same as the existing rule, which 
has not posed such difficulties in practice.
    Paragraph (b)(7) requires that top rails and midrails not be so 
long as to constitute a projection hazard. This provision, which is 
identical to the proposed provision, is based on existing 
Sec. 1926.500(f)(l) and (f)(1)(vi)(d). No comments were received 
regarding this provision.
    Paragraph (b)(8) prohibits the use of steel banding and plastic 
banding as top rails or midrails. This provision is identical to the 
proposed provision. While such banding can often withstand a 200-pound 
load, it can tear easily if twisted. In addition, such banding often 
has sharp edges which can easily cut a hand if seized.
    While OSHA did not receive any comments specifically on proposed 
paragraph (b)(8), it did receive a recommendation from the ACCSH (Tr. 
6-9-87, p. 212) regarding a similar provision in proposed subpart L 
(Sec. 1926.451(e)(4)(xiii). In particular, the ACCSH suggested that 
OSHA ban the use of manila rope and plastic rope as well as steel and 
plastic banding as top rails for scaffold guardrail systems. This 
recommendation reflected ACCSH's concern that manila rope and plastic 
rope lose strength quickly when exposed to water and sun.
    In Issue M-3 of the hearing notice (53 FR 2054, January 26, 1988), 
OSHA discussed the ACCSH recommendation, stating that ACCSH had 
recommended that OSHA add a ban on the use of manila rope or plastic 
rope for top rails or midrails of guardrail systems used on scaffolds. 
OSHA also noted that ACCSH had not made a similar recommendation for 
change in proposed subpart M. OSHA requested comment on whether or not 
the ACCSH concern should be addressed in the final rule for subpart M.
    At the hearing, the Scaffold Industry Association (SIA) (Tr. 3-22-
88 pp. 160-161) testified that it should not be necessary to restrict 
the type of materials used since OSHA established the strength 
requirements for guardrail systems. Upon further questioning, the 
participant suggested (pp. 165-166) that experts in the field should 
address the recommendation and again stated his belief that as long as 
the rope met the strength criteria, it should be considered adequate.
    OSHA also received comments on Issue M-3 from three other parties. 
One commenter (Ex. 6-3) stated the following:

    Manila and plastic rope used as guardrails for short periods of 
time until more permanent rails can be installed should not be 
banned from use providing they are capable of supporting a 200-pound 
load applied in any direction with a minimum of deflection.

    In addition, the commenter noted that while some lumber is subject 
to deterioration, no lumber is banned. Finally, the commenter stated 
that OSHA could insert a note or warning in the standard regarding 
deterioration hazards and that the Agency could add an inspection 
requirement such as was proposed for safety nets in 
Sec. 1926.502(c)(5). The other two commenters (Exs. 6-5 and 6-17) 
stated that OSHA should ban the use of manila rope or plastic rope from 
use as midrails or top rails.
    Based on an evaluation of the record, OSHA has decided not to ban 
the use of manila or plastic rope. Instead, OSHA has determined that 
the concerns of the ACCSH are appropriately addressed by adding a new 
provision in Sec. 1926.502(b)(15), discussed below, which requires 
employers to inspect top rails and midrails if manila, plastic or 
synthetic rope has been used, as frequently as necessary to ensure that 
the rails have not deteriorated beyond their ability to meet the 
strength requirements set forth in Sec. 1926.502(b)(3), above.
    Paragraph (b)(9) of the final rule, like the proposal, requires 
that top rails and midrails be at least one-quarter inch (0.6 cm) in 
nominal diameter or thickness. OSHA believes that the minimum thickness 
requirement is needed to prevent the use of rope that would cause cuts 
or lacerations. In addition, final rule paragraph (b)(9) adds a new 
requirement that top rails constructed of wire rope shall be flagged at 
not more than 6-foot intervals with high-visibility material. This 
requirement supplements the strength requirements for guardrails 
specified in paragraphs (b) (3), (4), and (5) of this section. The 
purpose of this requirement is to assure that rails made of high 
strength materials are not so thin that a worker grabbing a rail is 
injured, such as by cuts or lacerations, because of the small size of 
the rail.
    CAL/OSHA (Ex. 2-15) suggested that OSHA require top rails, such as 
those made with wire rope, to be made more visible by installing bits 
of flagging or cloth strips at 10-foot intervals. Roberts Safety 
Consultants (Ex. 2-18) supported the requirement for \1/4\ inch minimum 
diameter wire rope. Maryland Occupational Safety and Health officials 
(MOSH) (Ex. 2-31) commented that OSHA should specify that the provision 
is referring to wire rope. The Tennessee Valley Authority (TVA)(Ex. 2-
20) suggested that OSHA eliminate the provision since the standard 
already contains a strength requirement.
    OSHA agrees with California that wire rope, especially the \1/4\ 
inch diameter rope, could be difficult to see, and has therefore 
incorporated in the final rule their suggestion that the rope be 
flagged for visibility. To maintain consistency with other requirements 
in the final rule, such as those for flagging of warning lines in 
Sec. 1926.502(f)(2)(i) and flagging of control zone lines in 
Sec. 1926.502(g)(3)(i), OSHA is requiring flagging at 6-foot intervals 
rather than at 10-foot intervals. OSHA also notes that flagging of wire 
rope is a common industry practice.
    In response to TVA's comment, OSHA notes that, as discussed above, 
this provision addresses the need to protect workers from cuts and 
lacerations, not the strength of the wire rope.
    Paragraphs (b) (10) through (13) address the use of guardrail 
systems. The requirements in paragraphs (b) (10) through (13) are 
identical to those found in paragraphs (b)(11) to (b)(14) of the 
proposed rule. OSHA had also proposed specific requirements pertaining 
to guardrail systems used at hoisting areas during the performance of 
roofing operations on low-slope roofs (proposed at paragraph (b)(10)). 
However, because revised Sec. 1926.501(b)(3) addresses fall protection 
at all hoist areas, including hoist areas on low-slope roofs where 
roofing operations are being performed, there is no need to have the 
additional, redundant requirements proposed at paragraph (b)(10) and 
they have been deleted in the final rule. Further discussion on the 
remaining provisions (b)(11) to (b)(13) can be found in the notice of 
proposed rule for subpart M [51 FR 42724].
    Paragraph (b)(14) provides that guardrail systems on ramps and 
runways be erected along each unprotected side or edge. The proposed 
requirement contained essentially the same requirements as existing 
Sec. 1926.500(d) (2) and (3). The proposed rule contained an exception 
for installing guardrails on ramps and runways where the guardrails 
would interfere with the operation of work as long as the ramp or 
runway was 18 inches wide. Existing Sec. 1926.500(d)(3) also allowed 
this exception. However, based on OSHA's enforcement experience, OSHA 
has decided that the exception is no longer valid.
    It is OSHA's contention that the purpose of installing guardrails 
on ramps and runways is solely to keep employees from falling off the 
unprotected sides or edges of such ramps and runways when employees are 
exposed to falls of 6 feet or (1.8 m) or more to a lower level. OSHA 
recognizes that there may be circumstances where the movement of 
materials or equipment across ramps or runways would be impeded by 
guardrails and situations where that interference is such that 
compliance with this provision would be infeasible (i.e., the work 
cannot be done) or would create a greater hazard. OSHA believes, in 
general, that preplanning of work will ensure that compliance with 
paragraph (b)(14) is feasible and does not create a greater hazard.
    CAL/OSHA (Ex. 2-15), noted that the proposed provision would be the 
subject of considerable interpretation and stated that OSHA should 
provide examples of operating conditions that would permit employers to 
follow the guardrail configuration described. The commenter also stated 
that ramps should be 2 feet wide and railed on both sides.
    OSHA notes that the existing rule was based on ANSI A12.1-1967, 
Safety Requirements for Floor and Wall Openings, Railings, and Toe 
Boards, which provides examples of special purposes where operating 
conditions may preclude the use of guardrails on one side of the 
runway. Such purposes were identified as oiling, shafting or filling 
tank cars. OSHA also notes that the ANSI A1264.1-1989, Safety 
Requirements for Workplace Floor and Wall Openings, Stairs, and Railing 
Systems, which replaced the ANSI A12.1-1967, also contains the same 
provision, but does not provide examples of special purposes which 
necessitate omitting guardrails on one side. In any event, the example 
provided covered non-construction work, raising further questions about 
the appropriateness of the exception. Upon further consideration and 
evaluation of the proposed provision, OSHA has determined that since it 
cannot readily identify situations where operating conditions would 
preclude the use of guardrails on one side it should not write an 
exception into the rule and, therefore, the agency has no reason to 
specify a platform width. OSHA agrees with CAL/OSHA that the provision 
would be subject to wide interpretation. As a consequence, OSHA has 
decided to delete this provision from the final rule.
    Paragraph (b)(15), which was not part of the proposed rule, 
requires that manila, plastic and synthetic rope used in guardrail 
systems be inspected as frequently as necessary to detect 
deterioration. This new requirement has been added in response to the 
comment received on Issue M-3, discussed above, in which OSHA solicited 
information on the need to prohibit the use of manila and plastic rope. 
As discussed earlier in this preamble, OSHA has determined that 
paragraph (b)(15) appropriately responds to ACCSH's concern that such 
ropes may deteriorate and lose their strength.
    OSHA observes that Non-mandatory Appendix B contains detailed 
specifications for minimum sizes of guardrail system components. These 
specifications are based on existing Sec. 1926.500(f)(1) (i), (ii), and 
(iii) and should provide useful information to help employers to design 
guardrail systems. The transfer of this guidance from existing 
regulatory text to a non-mandatory appendix does not reduce the level 
of safety achieved through compliance with the existing standard. The 
existing specific provisions are consistent with the performance-
oriented requirements in the final rule. The promulgation of non-
mandatory Appendix B removes redundant provisions from the standard.
    Paragraph (c)--Safety net systems. This paragraph replaces the 
criteria in existing Sec. 1926.105--Safety nets. OSHA has relocated the 
regulation of safety nets to subpart M as part of the Agency's effort 
to consolidate the standards that generally cover protection of 
construction employees from fall hazards.
    OSHA received one general comment on this paragraph. The ISEA (Ex. 
2-23) suggested that OSHA refer to safety nets as personnel nets, so as 
to differentiate personnel nets and debris nets. This commenter also 
suggested that debris nets should be addressed separately. OSHA has not 
taken any action with respect to the suggestion because the criteria 
set forth apply to nets used to protect employees from the hazards of 
falling. If an employer selects and uses a net labeled as a ``debris 
net'' to provide fall protection for employees, then such net must meet 
all of the criteria and conditions for use set forth in the safety net 
section. On the other hand, just because a net is labeled a ``personnel 
net'' does not mean that it is acceptable to OSHA for use as a safety 
net.
    Paragraph (c)(1) requires the installation of safety nets as close 
as practicable under the walking/working surface where employees need 
to be protected, but in no case more than 30 feet below such level. 
Both proposed paragraph (c)(1) and existing Sec. 1926.105(a) require 
that nets be installed no greater than 25 feet below the working level. 
However, the recently revised ANSI A10.11-1989 standard for nets allows 
net installation 30 feet below the working level. In addition, OSHA 
notes that the National Bureau of Standards study of nets included test 
data of 30-foot falls. The data indicate there is no significant 
difference between a 25 and a 30-foot fall into a net (Reference 14). 
OSHA also notes that both the existing rule and the proposed rule were 
based on earlier versions of the ANSI consensus standard which 
prescribed that nets be positioned not more than 25 feet below the 
working level.
    Therefore, based on the record developed in the course of this 
rulemaking, OSHA has determined that a safety net installed as much as 
30 feet below a walking or working level will provide adequate fall 
protection and has revised proposed paragraph (c)(1) accordingly.
    Paragraph (c)(1) also requires that when nets are used on bridges, 
there must be an unobstructed fall to the net. In other words, nets 
must not be used when a falling employee could hit an obstruction 
before reaching the net. This is a new provision added in response to 
comments received on Issue #13 discussed below.
    In proposed paragraph (c)(1), OSHA provided an exception to the 
proposed 25-foot limitation in the case of nets used in bridge 
construction. However, that portion of the proposed rule has not been 
finalized. The proposed paragraph required only one level of nets 
during bridge construction regardless of the distance between the 
walking/working surface and the net. However, the record developed on 
that proposed provision supported limited the fall distance to 30 feet.
    OSHA solicited input regarding the appropriateness of the proposed 
exception in Issue #13. In particular, the Agency requested comment on 
whether personal fall arrest systems should be required for employees 
performing bridge construction work when employees do not have an 
unobstructed fall to a safety net. In response, the ACCSH recommended 
that OSHA allow one level of nets during bridge construction, provided 
the fall was unobstructed and the fall distance did not exceed 25 feet. 
Otherwise, the Advisory Committee recommended that affected employees 
also use personal fall arrest systems. One ACCSH member noted that the 
wording of the proposed provision could allow falls from 75 or 80 feet, 
and that even if the fall were unobstructed, injuries would occur. That 
ACCSH member also spoke of two such cases where employees were 
paralyzed from the waist down after falling into a net. (Tr. 6/10/87; 
pp. 137-141).
    The ACCSH recommendation was echoed by other commenters. Bristol 
Steel and the NEA (Exs. 2-12 and 2-43) commented that during erection 
or painting of tall steel bridges, such as trusses and arches, one 
level of netting would not be adequate. They also stated the following:

    Not only is there the problem of falling employees striking 
bridge structural members before they fall into the safety net, but 
also the fall distance from upper bridge levels of the safety nets 
will frequently exceed 50 feet or even 100 feet or more. Safety nets 
on the upper levels of such bridges are not a desirable or feasible 
alternative * * *.

These commenters suggested that OSHA require ``safety railings in 
accordance with subpart R (Steel Erection), body belt/harness systems, 
or safety monitoring systems where the fall distance into the safety 
net exceeds 25 feet.'' They also identified types of bridge 
construction where ``the risk of harm from striking bridge members 
during a fall is significantly reduced. Most falling employees will be 
deflected by bridge members with forces not so great as to cause 
serious harm * * *.'' They did not feel that these situations warranted 
both safety nets and body belt systems, but they did believe body belt 
systems, in addition to safety nets, were warranted when the fall 
distance exceeded 25 feet.
    MOSH (Ex. 2-31) commented that they could not understand why safety 
nets were not being required for second levels of bridges, noting that 
they had experienced severe accidents involving employees falling from 
the top chords of bridges.
    The AGC (Exs. 2-16, 2-47 and 2-92) commented that many site work 
situations do not allow for systems such as body belts and that ``The 
standard should reflect existing conditions and permit flexibility.''
    Many commenters (Exs. 2-19, 2-20, 2-23, 2-36, 2-46, and 2-50) 
indicated that a single level of safety nets may not provide adequate 
fall protection on bridges, particularly where an employee could strike 
a bridge structural member before hitting the net. These commenters 
also indicated that personal fall protection should be required in 
addition to nets or that additional netting systems should be required.
    OSHA has determined that a one-level net system does not provide 
adequate protection if there are intervening members between the 
working surface and the net which an employee might strike. In 
addition, OSHA notes that even when the fall area is unobstructed, one 
level of nets will not provide adequate protection if the fall distance 
exceeds 30 feet. In such situations, the record demonstrates that 
severe injuries are likely to occur (Exs. 2-12, 2-31, and 2-43). 
Therefore, the final rule does not permit a one-level net system when 
the fall distance exceeds 30 feet. When the distance exceeds 30 feet, 
additional netting will have to be provided or employees will have to 
be protected by another fall protection system such as a personal fall 
arrest system.
    Paragraph (c)(2) sets minimum horizontal projection requirements 
for safety net systems, based on the vertical distance between the 
working level and the net. Existing Sec. 1926.105(c)(1) requires that 
nets extend 8 feet. Proposed paragraph (c)(2) would have required that 
nets extend 15 feet. In the proposal, OSHA explained that the National 
Bureau of Standards (NBS) had conducted tests to evaluate the proposed 
requirement. Their findings indicated that at least 13 to 15 feet would 
be required to fully contain a body falling 25 feet (Ex. 14:50). Based 
on their findings, OSHA proposed the 15-foot requirement. Since that 
time, however, the ANSI A10.11 Committee issued a revision to the 
consensus standard on Personnel and Debris Nets, in which it varied the 
horizontal distance of the net according to the vertical distance 
between the working level and the net. The ACCSH, in turn, recommended 
that OSHA replace the 15-foot requirement of proposed paragraph (c)(2) 
with the language of the then-draft ANSI A10.11 provision (subsequently 
adopted by ANSI in 1989) [Tr. 6-10-87, pp. 197-199].
    There were few comments on proposed paragraph (c)(2). The TVA (Ex. 
2-20) commented that OSHA should include criteria on rigging supports 
to extend safety nets the required distance. OSHA observes that the 
rigging supports are considered part of the total safety net system for 
which OSHA has specified criteria. The Builders Association of Missouri 
(Ex. 2-42) commented that the cost would be increased to extend the 
nets the proposed distance of 15 feet and the danger to workers would 
increase. (The commenter did not explain how workers would be at 
increased risk.)
    In addition, the Building Trades Employee Association of Boston and 
Eastern Massachusetts, Inc. (Ex. 2-26) stated that in many cases an 
employer will not have 15 feet of horizontal space at the perimeter of 
a building in which to construct a safety net system, due to the 
proximity of other structures. OSHA agrees that there may be 
circumstances where it is not possible to have a safety net system 
extend far enough to satisfy the extension requirements of the proposal 
or the final rule. Under those circumstances, employers would have to 
select another fall protection system.
    OSHA points out that employers have the choice of two other fall 
protection systems--guardrail systems or personal fall arrest systems--
when safety net systems cannot be installed in a way that will comply 
with Sec. 1926.502(c). The purpose of this section is merely to set out 
the criteria that must be followed when safety nets are chosen by the 
employer to meet the duty to provide fall protection set in 
Sec. 1926.501.
    OSHA raised Issue M-4 in the hearing notice [53 FR 2048], asking 
for input regarding the ACCSH safety net recommendation. In the Issue, 
OSHA discussed the concerns of ACCSH regarding the above-mentioned 
study performed by the National Bureau of Standards which indicated 
that nets which extended only 8 feet from a structure would not catch 
someone who had fallen 25 feet [Tr. 6/10/87; pp. 198-199]. Issue M-4 
also discussed the draft document of the ANSI A10.11 Committee 
(Personnel and Debris Nets) which would replace the current ANSI 
Standard on Safety Nets in which ANSI varies the horizontal distance of 
the net, depending on the vertical distance from the walking/working 
surface to the net. There was no testimony or other information 
submitted in relation to Issue M-4.
    Paragraph (c)(3) requires nets to be rigged with sufficient 
clearance under them to prevent contact with the lower level when the 
net is subjected to the impact forces specified in paragraph (c)(4). 
This is basically the same requirement as in existing 
Sec. 1926.105(c)(l), and the proposed rule. There were no comments on 
the proposed provision.
    Paragraph (c)(4) specifies the capacity requirements for safety 
nets and safety net installations. The paragraph requires employers 
either to show that nets and net installations meet the capacity 
requirements by conducting drop tests meeting designated criteria or, 
when an employer can demonstrate that drop testing is not feasible or 
practicable, certify, based on information received from a qualified 
person, that the net and net installation meet all specified criteria. 
One example of where a drop test may not be feasible or practicable is 
when the net is strung over a public thoroughfare and the test could 
endanger people below. Another example is where the test weight cannot 
be readily retrieved from the net once it has been dropped.
    For the purposes of paragraph (c)(4), OSHA considers two or more 
net panels joined together to be one net. Safety net installations 
which do not share the same net are considered to be separate systems. 
In addition, each time a safety net system is erected, it is considered 
to be a separate installation which must be tested or certified. This 
is a clarification of existing Sec. 1926.105(b), which requires all net 
installations to be drop-tested. Paragraph (c)(4)(i) sets forth the 
criteria for performing drop tests on net installations. In most 
respects, these criteria are the same as the requirements in section 8 
of ANSI A10.11-1979, proposed paragraph (c)(4)(i), and section 8 of 
ANSI A10.11-1989, except that the final rule requires the test to be 
conducted from a level at least 42 inches (1.1 m) above the highest 
walking/working surface on which employees are to be protected as 
opposed to the 25-foot height required by ANSI, so that the test more 
closely resembles the type of fall from which the worker is to be 
protected. OSHA believes the use of a 400-pound weight to test the 
system will ensure that a proper margin of safety is obtained. OSHA 
also notes that in the proposal the drop test would have been conducted 
by dropping the weight from the highest walking/working level on which 
employees were to have been protected. The final rule adds 42 inches to 
this height to take into consideration the center of gravity of the 
95th percentile man and also to take into consideration those 
situations where the net is installed at the same level from which the 
employee is to be protected.
    There were several comments on proposed paragraph (c)(4), 
particularly with regard to the exception proposed in paragraph 
(c)(4)(ii). The ISEA (Ex. 2-23) objected to the proposed certification 
in lieu of drop test provision, stating that nets will probably rarely 
undergo an actual drop test. As indicated above, OSHA will allow 
certification only when the employer can demonstrate that it is not 
feasible or practicable to conduct a drop test. The ISEA also stated 
that prototype tests should be required, stating that on-the-job drop 
test could weaken the nets. However, OSHA is concerned with the total 
system (i.e., the net and the net installation) and prototype tests do 
not address the Agency's concern.
    NIOSH (Ex. 2-33) suggested that OSHA clarify whether testing will 
be required each time the safety net is moved to a different location 
at the job site. It was OSHA's intent that a net be tested or certified 
whenever it is newly installed at a location before it is allowed to be 
used for fall protection system. OSHA has rewritten the provision to 
make it clear that nets must be drop-tested at the jobsite following 
initial installation; whenever nets are relocated; whenever a major 
repair to the net has been made; and at 6 month intervals when the net 
has been left in the same location.
    The Building Association of Missouri (Ex. 2-42) commented that 
``Drop tests should not be required nor even allowed on nets.'' They 
stated their belief that drop tests make nets unsafe, citing the 
requirement in existing Sec. 1926.104(a) that employers remove a 
lanyard from service if it has been subjected to in-service loading. 
Based on its experience with fall protection systems, the Agency has 
come to the conclusion that safety nets, unlike lanyards, can remain in 
use after loading if the pertinent criteria can still be satisfied.
    CAL/OSHA (Ex. 2-15) commented that the certification requirements 
were unclear. OSHA has revised proposed paragraph (c)(4)(ii) to be 
specific in how and who must certify the net and net installation.
    In addition, the MSA (Ex. 2-35) recommended that after the net 
installation test, the net section should be examined by a qualified 
person and replaced if needed. OSHA notes that paragraph (c)(5), either 
as proposed, or as revised in the final rule (see below), effectively 
requires the inspection of nets and replacement of defective components 
necessary to ensure that nets are always in safe condition.
    Paragraph (c)(5) prohibits the use of defective nets and requires 
safety net systems to be inspected at least once a week for wear, 
damage, or other deterioration. The provision also requires inspection 
after any occurrence which could affect the integrity of the safety net 
system. Defective components must be removed from service. This 
provision was proposed as a new requirement. Issue #9 of the proposal 
asked if the proposed frequency of inspection was appropriate. The 
Issue noted that similar requirements had been proposed for body belt/
harness systems and positioning device systems.
    There were several comments relating to the appropriate frequency 
of net inspection. The ACCSH recommended that nets be inspected weekly 
or whenever any object has been dropped into the net that is of such 
weight that it might damage the net. (Tr. 6/10/87, pp. 130-131.) The 
National Constructors Association (NCA) and the ANSI Z359 Committee 
(Exs. 2-45 and 2-50) commented that the frequency of inspection was 
appropriate as proposed. The NCA, however, noted its opposition to 
added paperwork.
    WMACSA, (Ex. 2-56), stated that record should be maintained of the 
results of the weekly inspection. Other comments, including Bristol 
Steel, AGC, and NEA, stated that weekly inspection, itself, was not 
necessary; that nets should be maintained in a satisfactory condition; 
and that weekly inspection would impose recordkeeping burdens without 
enhancing employee safety. (Exs. 2-12, 2-16, 2-43, 2-46, 2-47, 2-51 and 
2-92).
    OSHA has determined that while keeping records of inspections may 
assist employers in meeting their obligations under this paragraph, 
maintaining records of net inspections will not directly enhance 
employee safety. It is the routine performance of the inspection and 
the removal of any defective components that leads to employee safety. 
Thus, OSHA has revised the language of the final rule to prohibit the 
use of defective nets and to require that nets be inspected at least 
once a week to determine their condition. If any defects are discovered 
at the time of inspection, the defective components must be removed and 
replaced. OSHA is making the slight language modification because it 
realizes that although once a week inspections should ordinarily be 
sufficient to detect any net defects, there are some circumstances that 
may require employers to conduct more frequent inspection. For example, 
as ACCSH mentioned, when large weights have fallen into the net, the 
net must be inspected. Or, as Dr. Nigel Ellis stated in his comment 
(Ex. 2-36): ``Inspection should be regular and at frequent intervals 
depending on the use and environment.''
    The BCMALU (Ex. 2-46) noted that, ``where high winds or storms or 
hazardous chemicals have been used in the area, it becomes a necessity 
to inspect the safety nets as often as may be needed.'' Consequently, 
the revised language requires inspection at least weekly and as often 
as necessary to ensure that defective nets are not used.
    Paragraph (c)(6) requires debris and tools to be removed as soon as 
possible from the net, but not later than the start of the next work 
shift. Such materials pose safety hazards to anyone who falls into the 
net. This provision was also proposed as a new requirement. The one 
commenter on the proposed provision, (Ex. 2-26), stated that the 
proposed requirement created a serious safety hazard and suggested that 
OSHA reconsider the proposed language. OSHA considers clearing the net 
of debris necessary to prevent injury to workers who may fall into the 
net and believes this task can be performed without undue risk to 
employees. Therefore, OSHA promulgates paragraph (c)(6) as proposed.
    Paragraph (c)(7) specifies the maximum allowable mesh opening, 
limiting the size of the opening to a maximum of 36 square inches. This 
requirement is the same as the proposed requirement. Existing 
Sec. 1926.105(d) also provides for a maximum of 6 inches (15 cm) on any 
side of an opening, but did not explicitly limit the size of the 
opening. OSHA proposed the limit because mesh openings can be 
manufactured with more than four 6-inch sides; and a limit of 36 square 
inches is necessary to ensure that an employee's head cannot go into it 
during a fall, possibly breaking the employee's neck. This requirement 
is essentially identical with that in paragraph 6.3 of ANSI A10.11-
1989, Personnel and Debris Nets. There were no comments on the proposed 
provision.
    Paragraph (c)(8) specifies a minimum breaking strength of 5,000 
pounds for border ropes used for net webbing. This requirement is 
essentially the same as in the proposal and in existing 
Sec. 1926.105(d). There were no comments on the proposed provision.
    Paragraph (c)(9) requires connections between net panels to be as 
strong as integral components and to be spaced not more than 6 inches 
apart. This provision is identical to the proposed provision. Existing 
Sec. 1926.105(f), in effect, sets the same strength requirement as 
paragraph (c)(9), but does not contain a 6-inch spacing requirement. 
OSHA proposed this as a new requirement, basing it on paragraph 9.3 of 
the ANSI A10.11-1979. OSHA notes that this requirement is also 
consistent with paragraph 10.4 of the ANSI A10.11-1989.
    The NEA (Ex. 2-43) commented that the new ANSI A10.11 safety net 
standard required a 1-foot spacing between connectors (rather than 6 
inches as OSHA proposed) when two nets were joined together, and that 
the OSHA requirement should be consistent with the ANSI requirement 
which has the support of contractors and net manufacturers. OSHA notes 
that, as discussed above, ANSI specifies 6-inch (15 cm) spacing, thus 
OSHA's requirement is consistent with the ANSI A10.11 standard.
    The requirement in existing Sec. 1926.105(d) that all new nets must 
meet accepted performance standards of 17,500 foot-pounds minimum 
impact resistance, as determined and certified by the manufacturer, was 
proposed to be deleted as it applied only to the net itself, and not to 
the complete net installation. OSHA believes the important 
consideration is the safety net system as a whole, and that the 
provisions of paragraph (c)(4) of this section are sufficient to assure 
proper safety for employees. The best net can be rendered useless by an 
improper installation. For these same reasons, the existing 
Sec. 1926.105(d) requirement for a label of proof test was also 
proposed to be deleted. In addition, existing Sec. 1926.105(e) 
requiring forged steel safety hooks or shackles to fasten nets to 
supports was proposed to be deleted. The existing rule is unduly 
specific as there are other acceptable methods such as wire rope to 
fasten nets to supports. OSHA received no comments on those proposed 
deletions and has proceeded to make those deletions in the final rule.
    Paragraph (d)--Personal fall arrest systems. This paragraph 
replaces all of the existing provisions in Sec. 1926.104--Safety Belts, 
Lifelines, and Lanyards and relocates coverage of personal fall arrest 
systems to revised subpart M. This is being done as part of the 
consolidation of fall protection requirements for construction.
    There have been a number of revisions to the proposed requirements 
for body belt/harness systems. First, the title of the paragraph has 
been changed to ``personal fall arrest systems.'' The reason for this 
change was explained in the definitions section, where OSHA discussed 
its substitution of the term ``personal fall arrest systems'' for 
``body belt/harness systems.'' Many provisions have been revised, 
relocated or added as discussed below.
    Second, OSHA is phasing out, and then prohibiting, the use of body 
belts as a component of personal fall arrest systems. After December 
31, 1997, body belts will no longer be permitted for use in a personal 
fall arrest system. They will, however, continue to be acceptable for 
use as part of a positioning device system [See paragraph (e)] or as a 
part of a ladder safety device system required in subpart X of part 
1926 since positioning device systems and ladder safety device systems 
are not used to arrest a fall. The Agency recognizes that an immediate 
ban on the use of body belts in personal fall arrest systems would 
impose unreasonable burdens on employers. OSHA believes this phase out 
period will allow all body belts currently in use to be used through 
their life expectancy, eliminating any economic burdens to employers 
and permitting manufacturers to prepare to meet the demand for body 
harnesses.
    In Issue #14 of the proposal, OSHA discussed various reports and 
studies which recommended restricting or banning the use of body belts. 
Also in Issue #14, OSHA solicited information on whether it should 
restrict the use of body belts as personal fall arrest systems and also 
asked for additional information on the effects of prolonged suspension 
in a body belt among other questions. OSHA referenced a number of 
studies in the proposal (Exs. 3-7, 3-9, and 3-10) which indicated that 
persons suspended in body belts suffer internal injuries and cannot 
tolerate suspension long enough to allow for retrieval. The rulemaking 
record for Powered Platforms also contained studies (Docket S-700, Exs. 
11-3, 11-4, 11-5, 11-6, 2/21-42) which indicated that the initial fall 
impact and pressure exerted during suspension made body belts 
inappropriate for use in a personal fall arrest system. OSHA notes that 
all comments received on the proposed rule for powered platforms were 
referenced in the proposal for subpart M (Ex. 3-13).
    In response, OSHA received a number of comments including several 
that requested their comments from the Powered Platforms rule be 
considered (Exs. 2-23, 2-36, and 2-50). A number of commenters 
indicated their belief that the biggest problem with a ban on the use 
of body belts would be worker acceptance (Exs. 2-6, 2-9, 2-19, and 2-
41). Typical of such comments were ``It is hard enough to get the 
typical construction worker to wear a safety belt let alone a full 
harness * * * a harness, which is more uncomfortable than the belt * * 
* would have more resistance from workers to wear them * * *'' (Ex. 2-
9). Other commenters (Exs. 2-16, 2-27, and 2-51) noted that they 
currently use body belts and have not had any problems. The AGC (Exs. 
2-16, 2-47, 2-92, and 2-103) stated that body belts have been used with 
``only positive results'' and that it would be appropriate to let 
employers choose between body belt and body harness. The commenter did 
note specific circumstances (manholes and small diameter tanks) where 
it agreed that employees would be better protected through the use of 
body harnesses. Also, commenters (Exs. 2-19, and 2-140) indicated that 
compliance with the proposed rule (Sec. 1926.502(d)) would provide 
adequate protection for employees using body belts in personal fall 
arrest systems. OSHA also points out that these comments were made 
before 1988 and since that time, many changes have taken place in the 
construction industry. Another commenter (Ex. 2-154) stated that OSHA 
should allow continued use of body belts for fall protection except 
where ``a person is working alone or could not be readily rescued.''
     USTAG (Ex. 9-33 in the powered platform rulemaking record), stated 
the following, among other comments:

    The restriction on forces for body belt and chest-waist harness 
systems is based on our serious concern about the suitability of 
body supports other than the full body harness with a sub-pelvic 
(buttocks) support as well as other design considerations. There is 
a growing body of evidence which points to hazards related to the 
use of body supports other than an appropriate fully body harness. 
Studies performed in Europe and by the U.S. Air Force indicate high 
risks associated with the body belt in both fall arrest and 
suspension modes. Further, the possibility of falling out of a body 
belt and chest-waist harness is significant and has appeared in 
accident reports.
    For these reasons we recommend that use of body belts and chest-
waist harnesses be restricted to a free fall distance of two feet 
and an actual loading of 900 pounds.

USTAG also noted that British standards impose restrictions on the body 
belt; French standards prohibit the use of body belts; German standards 
essentially prohibit the use of body belts, except in certain 
applications, and that the draft ISO standards put conditions on the 
use of body belts.
    OSHA received a number of comments (Exs. 2-3, 2-20, 2-36, 2-46, 2-
50, 2-89, and 2-135) which supported a prohibition on the use of body 
belts for fall arrest. For example, one commenter (Ex. 2-3) stated 
``The use of body belt systems should be prohibited in favor of body 
harness systems. There is a possibility of back injuries associated 
with the use of safety belts.'' Another commenter (Ex. 2-89) stated, 
``Members of the SSFI would recommend the following: a) Body Belts be 
used as a work positioning device; and, b) Body Harnesses should be 
referred to as a fall arrest device.''
    OSHA believes that U.S. workers should be afforded the same level 
of protection as workers of other nations, and that the evidence in the 
record clearly demonstrates that employees who fall while wearing a 
body belt are not afforded the level of protection they would be if the 
fall occurred while the employee was wearing a full body harness. In 
addition, RTC (Ex. 2-36) presented evidence of injuries resulting from 
the use of body belts. The best available evidence the Agency has at 
this time requires it to ban the use of body belts as part of a 
personal fall arrest system after a reasonable period to allow existing 
belts to be worn out. While the ban of body belts begins January 1, 
1998, OSHA encourages employers to phase out the use of body belts in 
personal fall arrest systems as soon as possible so that employees may 
be spared exposure to the injuries which have resulted from body belt 
use.
    In addition, OSHA points out that paragraph (d)(16) requires that 
personal fall arrest systems, when stopping a fall, to limit maximum 
arresting forces on the employee to 900 pounds (4 kN) when using a body 
belt. Thus, employers who continue to use body belts until the ban, 
must rig the system to ensure that fall arrest forces are at or below 
900 pounds. Essentially this will require limiting the free fall 
distance, the use of shock absorbing lanyards and other measures to 
meet the criteria for using body belts as part of a personal fall 
arrest system.
    Today, many employers permit only the use of body harnesses, having 
recognized the limits of body belts. While OSHA has no direct record 
evidence to support this claim, it has received much informal 
communication from employers and from manufacturers which indicate that 
there is already a movement toward the use of body harness instead of 
body belts for fall arrest situations. In addition, worker acceptance 
of body harnesses has grown in the years since OSHA first proposed its 
fall protection rules in November 1986. As more and more prudent 
employers have, on their own, prohibited the use of body belts, 
compliance with and acceptance of the use of body harnesses has become 
increasingly routine. OSHA is also aware of efforts by segments of the 
fall protection equipment manufacturing community to develop a personal 
fall arrest system that is lighter and hence will increase worker 
comfort and proportionately increase worker acceptance and use of body 
harnesses.
    In addition, CAL/OSHA (Ex. 2-15) suggested that OSHA require 
permanent marking of all personal fall arrest system components with 
information that assures compliance with the pertinent standards, so 
that persons responsible for providing this equipment are spared the 
``substantial financial burden'' of verifying compliance. OSHA notes 
that such a requirement would not add to the inherent safety of the 
personal fall arrest system components. In addition, based on the 
response to Issue #18, discussed below in relation to 
Sec. 1926.502(d)(4) of the final rule, OSHA believes that equipment 
manufacturers are already voluntarily marking their products. 
Accordingly, any benefit resulting from addition of such a requirement 
would be minimal. Therefore, OSHA has not added the suggested language.
    Paragraph (d)(1) (proposed as paragraph (d)(9)) requires connectors 
to be drop forged, pressed or formed steel, or made of equivalent 
materials. This provision is essentially the same as the proposed 
requirement except that the term ``hardware'' was used in the proposed 
rule and the term ``connectors'' is used in the final rule. The reason 
for the change in the term was discussed above under the Definitions 
section. There were no comments on the substantive portion of the 
proposed provision.
    Paragraph (d)(2) (proposed as paragraph (d)(10)) requires 
connectors to have a corrosion-resistant finish, and all surfaces and 
edges to be smooth to prevent damage to interfacing parts of the 
system. This provision is essentially the same as the proposed 
provision except that, as explained above, the term connector is being 
used instead of the term hardware.
    In response to a comment in the powered platform rulemaking (Ex. 3-
13), the proposal raised Issue #22 to solicit comments, with supporting 
information, regarding the need to quantify the corrosion resistance 
requirements applying the ASTM Salt Spray Testing Standard.
    Some commenters (Exs. 2-12, 2-43 and 2-89) stated that the proposed 
requirement for corrosion resistance was sufficient. One commenter 
recommended ``* * * that hardware be tested to ASTM B-117-73, a 
nationally recognized test method to determine corrosion resistance.'' 
Another commenter (Ex. 2-36) stated ``[s]alt spray preconditioning of 
hardware is reasonable prior to static tensile strength tests.'' Also, 
a commenter (Ex. 2-50) stated ``[c]orrosion-resistance requirements 
should be quantified. Reference to the appropriate part of the ASTM 
Salt Spray Testing standard should be considered.''
     OSHA has determined that the proposed language provides adequate 
guidance to employers regarding the selection of corrosion-resistant 
hardware and that a requirement for salt spray testing would be 
unnecessary. Accordingly, the Agency has not adopted the recommended 
language from Issue #22.
    Paragraph (d)(3) requires that dee-rings and snaphooks have a 
minimum breaking strength of 5,000 pounds (22.2 kN). This provision 
corresponds to the final rule for Powered Platforms and is based on 
proposed paragraph (d)(16) which required that all components of body 
belt/harness systems whose strength was not otherwise specified (i.e. 
``hardware'') to be capable of supporting a minimum fall impact load of 
5,000 pounds (22.2kN). As noted above, the term hardware was used in 
the proposal to describe dee-rings and snaphooks, etc. This provision 
is consistent with the related provisions and replaces existing 
Sec. 1926.104(f), which requires that all hardware be capable of 
withstanding a tensile load of 4,000 pounds, but which does not specify 
where the 4,000 pound load is to be applied. There were no comments 
relating to this provision.
    Paragraph (d)(4), which was not part of the proposed rule, requires 
that dee-rings and snaphooks be 100 percent proof-tested to a minimum 
tensile load of 3,600 pounds (16 kN) without cracking, breaking, or 
taking permanent deformation. Issues 18, 20, and 24 of the proposed 
rule requested information on proper testing of personal fall arrest 
system components. Issue 18 solicited comments regarding the level of 
testing, in general, needed for personal fall arrest systems and system 
components and information regarding current industry practice. Issue 
20 discussed suggestions from participants in the powered platform 
rulemaking that OSHA require dynamic and static strength testing of 
dee-rings and snaphooks and solicited input regarding the need for such 
testing and the availability of recognized test methods. Issue 24 
specifically requested comments regarding the need for 100 percent 
proof-testing and suggestions for possible implementation.
    Some commenters on Issue 18 (Exs. 2-12, 2-43 and 2-45) stated that 
OSHA should set mandatory testing and labeling of prototypes to ensure 
that individual components comply. Two of those commenters, Bristol 
Steel and the NEA, (Exs. 2-12 and 2-43) also stated that testing of 
complete systems should be non-mandatory, left to the discretion of the 
manufacturer. The ISEA and MSA (Exs. 2-23 and 2-35) stated that most 
manufacturers of fall protection equipment test and label their 
products according to the ANSI A10.14-1975, ``Requirements for Safety 
Belts, Harnesses, Lanyards, Lifelines and Drop Lines for Construction 
and Industrial Use.'' In particular, the ISEA (Ex. 2-23) stated that 
``qualification testing should be mandatory and * * * should be 
monitored by an independent third-party organization. * * *'' Also, the 
R&TC a commenter (Ex. 2-36) stated that it ``tests equipment according 
to the subpart M requirements and labels according to draft 1910.129 at 
present.'' In addition, NIOSH (Ex. 2-33) stated that ``[m]anufacturers 
* * * are * * * testing to existing and proposed standards and 
regulations. The need exists for a single standard for testing of 
equipment whether it is employed in construction or general industry.''
    Two commenters (Exs. 2-36 and 2-50) who addressed Issue 20 
supported a requirement for testing. In particular, the ANSI Z359 
Committee (Ex. 2-50) recommended that OSHA require 100 percent proof-
testing at 3,600 pounds to ensure that the strength requirement was 
met. The commenter stated that heat treating and other manufacturing 
processes used did not always produce dee-rings and snap-hooks with the 
necessary strength.
    In response to Issue 24, several commenters (Exs. 2-12, 2-23, 2-41, 
2-43, and 2-45) stated that manufacturers should have the 
responsibility for testing their products. Another commenter (Ex. 2-35) 
stated that testing should focus on finished systems, not on 
components. Also, a commenter (Ex. 2-36) stated that 100 percent 
testing at 5,000 pounds would impose an unreasonable cost burden 
because hardware might break on its second proof loading. That 
commenter also noted that there is evidence that snaphooks in fall 
protection systems have broken due to low strength.
    The Agency has determined that proof-testing 100 percent at 3600 
pounds will provide appropriate reassurance that the hardware has the 
necessary strength for use in a personal fall arrest system. OSHA has 
revised the proposed rule accordingly. OSHA has already adopted this 
approach in Sec. 1910.66, Appendix C, Section I--Mandatory and has 
proposed to adopt it in proposed Sec. 1910.128(c)(7), as well (55 FR 
13436, April 10, 1990).
    Paragraph (d)(5), which is a new provision, requires that employers 
either use snaphooks that are sized to be compatible with the members 
to which they are connected, or use locking type snaphooks which have 
been designed to prevent disengagement. The Agency considers a hook to 
be compatible in size where the diameter of the dee-ring to which the 
snaphook is attached is greater than the inside length of the snaphook 
measured from the bottom (hinged end) of the snaphook keeper to the 
inside curve of the top of the snaphook, so that no matter how the dee-
ring is positioned or moved (rolls) with the snaphook attached, the 
dee-ring cannot touch the outside of the keeper so as to depress it 
open. The intent of this requirement is to prevent unintentional 
disengagement (roll out) of the snaphook. This provision also prohibits 
the use of nonlocking snaphooks after December 31, 1997.
    Issue 16 of the proposed rule addressed the design criteria for 
snaphooks, particularly with regard to the prevention of ``roll out'' 
(where snaphooks become accidentally disengaged during use). The Agency 
discussed information it had received regarding the need to mandate the 
use of locking snaphooks. Some input indicated that such a mandate was 
appropriate, while other informants suggested that properly designed 
and properly applied single action (nonlocking) snaphooks should be 
acceptable. OSHA requested suggestions, information and supporting 
rationale as to the type of snaphook that should be allowed.
    A number of commenters (Exs. 2-12, 2-16, 2-19, 2-23, 2-35, 2-43, 2-
45, 2-47 and 2-92) responded that there was no reason to bar the use of 
single-action snaphooks. Some (Exs. 2-23 and 2-45) contended that such 
a ban would be unreasonably expensive. Others (Exs. 2-12 and 2-43) 
stated that the increased hardware cost was ``an insignificant 
consideration,'' but that properly designed and applied single-action 
snaphooks have not posed problems. Another commenter (Ex. 2-35), stated 
``When used with a correctly matched dee ring, the assembly is as safe 
as any locking snaphook assembly * * *  The possibility of misuse 
exists, as some detractors have noted, but locking snaphooks are just 
as subject to misuse.'' Testimony favoring the continued use of single-
action snaphooks was presented at the rulemaking hearings (Tr. 144-146, 
3-22-88). That testimony, however, also acknowledges that the use of 
locking snaphooks facilitated the interchangeability of system 
components.
    Several commenters (Exs. 2-36, 2-41, 2-50 and 2-89) recommended 
that OSHA mandate the use of locking snaphooks, citing the roll-out 
problems experienced with single-action snaphooks. Two commenters (Exs. 
2-36 and 2-50) provided information which indicated that locking 
snaphooks were superior to single-action snaphooks in minimizing roll-
out accidents. In addition, the State of Maryland (Ex. 2-31) stated, in 
response to proposed paragraph (d)(19), ``Roll out is usually caused by 
an oversized hook. If the hook is matched to the dee ring, then roll 
out should not occur.''
    OSHA has determined, based on the rulemaking record, that in 
general, locking snaphooks provide a higher level of protection to 
employees than the single-action (nonlocking) type of snaphooks. Based 
on the above discussion, the Agency has determined that it is 
reasonably necessary to require the use of locking snaphooks, designed 
to prevent roll-out in personal fall arrest systems or in positioning 
device systems (See Sec. 1926.502(e)(7) of the final rule). In order to 
avoid imposing undue hardship on employers who already have non-locking 
snaphooks, the Agency will permit the continued use a non-locking 
snaphooks until December 31, 1997. OSHA believes, based on informal 
communication with manufacturers of snaphooks, that all of the 
nonlocking snaphooks currently in use will be worn out within the 3 
years and recommends that those worn out prior to that time be replaced 
with the locking type snaphooks. The more than 3 year phaseout allowed 
by this standard will eliminate any cost burdens on employers and is 
well within the life expectancy of equipment currently in use. OSHA 
notes this phaseout corresponds with the phase out period for the use 
of body belts as part of a personal fall arrest system. Therefore, the 
Agency has added paragraph (d)(5) to the final rule, requiring one or 
the other condition (locking snaphook or compatibly sized as described 
above) be met. Aside from the phaseout of nonlocking snaphooks, OSHA 
has already adopted a similar approach in Sec. 1910.66, Appendix C, 
Section I--Mandatory, and has proposed to adopt it in proposed 
Sec. 1910.128(c)(8) (55 FR 13436, April 10, 1990).
    Paragraph (d)(6) limits the use of snaphooks for certain 
connections unless the snaphook is a locking type, designed for those 
connections. Only locking snaphooks designed to be connected directly 
to webbing, rope or wire rope; to other snaphooks; to a dee-ring that 
already has another snaphook, or other connector attached; to a 
horizontal lifeline; or to any object that could depress the snaphook 
keeper because it is incompatibly sized or dimensioned in relation to 
the snaphook can be used for these connections. This provision reflects 
OSHA's determination that certain connections increase the likelihood 
of rollout and that only locking snaphooks specifically designed for 
such connections are needed to provide adequate assurance of employee 
safety. Accordingly, even before outright prohibiting the use of 
nonlocking snaphooks, OSHA is limited the circumstances in which they 
can be used.
    Proposed paragraphs (d)(17), (18) and (19) prohibited snaphook 
engagement to webbing, to other snaphooks and to a dee-ring with 
another snaphook attached, respectively, based on the Agency's concern 
about roll-out.
    One commenter (Ex. 2-31) stated, regarding proposed paragraph 
(d)(19), ``[i] n many instances to hook back to the dee ring is the 
only way to shorten the lanyard. OSHA should take this into 
consideration; weigh the hazard of rollout and how often it occurs to 
the hazard of falling a full six feet and being stopped by a lanyard.'' 
As discussed above in relation to paragraph (d)(5) of the final rule, 
the same commenter noted that rollout is usually caused by an oversized 
hook so rollout would not occur when the hook and dee-ring were 
compatibly sized and other commenters (Exs. 2-36 and 2-50) stated that 
only locking snaphooks should be permitted, because the locking 
mechanism prevents roll-out or inadvertent disengagement. In 
particular, one commenter (Ex. 2-50) suggested that OSHA prohibit the 
engagement of single action snaphooks to horizontal lifelines and to 
incompatibly sized or dimensioned objects because of roll-out and 
disengagement concerns.
    OSHA agrees that locking snaphooks provide the most adequate 
assurance against roll-out or inadvertent disengagement for the 
specified uses and that efforts to match the size of a single-action 
snaphook to its connection will not provide adequate assurance that the 
hook will remain attached to that connection under foreseeable 
conditions in use. OSHA has revised the proposed provisions 
accordingly. The Agency acknowledges that this provision will have no 
application after January 1, 1998, because after that time, non-locking 
snaphooks will not be used for any purposes. OSHA has already adopted 
this approach in Sec. 1910.66, Appendix C, Section I--Mandatory, and 
has proposed to adopt it in proposed Sec. 1910.128(c)(1) (55 FR 13436, 
April 10, 1990).
    Paragraph (d)(7) requires a device used to connect to a horizontal 
lifeline which may become a vertical lifeline to be capable of locking 
in both directions on the lifeline. This provision applies only when 
horizontal lifelines are used on suspended scaffolds or similar work 
platforms, and the horizontal lifeline would become a vertical lifeline 
if the scaffold or platform were to fall. This provision, which was not 
proposed, has been added in response to comments (Ex. 2-36 and 3-13) 
which pointed out that employees attached to a horizontal lifeline 
would face a fall hazard if either end of the horizontal lifeline 
support failed and the line became a vertical lifeline. In particular, 
OSHA notes that, potentially, a rope grab which did not lock in both 
directions on the lifeline would fail to hold, allowing the employee to 
fall to a lower level. OSHA has already adopted this approach in 
Sec. 1910.66, Appendix C, Section I--Mandatory, and has proposed to 
adopt it in proposed Sec. 1910.128(c)(2) (55 FR 13436, April 10, 1990).
    Paragraph (d)(8) requires that horizontal lifelines be designed, 
installed and used, under the supervision of a qualified person, as 
part of a complete personal fall arrest system which maintains a safety 
factor of at least two. Proposed paragraph (d)(14) would have required 
horizontal lifelines to have the tensile strength to support a fall 
impact load of 5,000 pounds, per employee using the lifeline, applied 
anywhere along the lifeline. Issue 25 of the NPRM solicited comments 
and information regarding the need to require that horizontal lifeline 
subsystems be designed by ``qualified persons'' and to provide more 
specific guidance for employers using horizontal lifelines.
    Two commenters on proposed paragraph (d)(14) (Exs. 2-23 and 2-35) 
asserted that the proposed rule did not adequately take into account 
the differences between vertical and horizontal lifelines. In 
particular, one commenter (Ex. 2-23) stated:

    The physics of the horizontal lifeline system are such that a 
line suitable for a vertical lifeline could be rigged so as to be 
completely inadequate for a horizontal lifeline. Since this is not 
necessarily obvious, earlier OSHA drafts included a chart specifying 
tensile strength versus angle of sag. Inclusion of this chart could 
avoid tragic mistakes and should be included in this section.

Another commenter (Ex. 2-89) stated:

    The 5000# tensile strength is not applicable to all situations 
and had been developed from the ANSI A10.14 Committee which is now 
withdrawn from being an ANSI standard. It would be the 
recommendation of the SSFI that lifelines be capable of an anchorage 
equal to 2 (two) times the maximum arrest force.

    Some commenters on Issue 25 (Exs. 2-12, 2-43, and 2-45) stated that 
OSHA should not add more detail to the proposed paragraph or require 
``qualified'' persons. In addition, two commenters (Exs. 2-12 and 2-43) 
asserted that the proposed 5,000 pound tensile strength requirement was 
too restrictive and was infeasible, adding that a system able to 
support twice the impact load, as provided in proposed paragraph 
(d)(12), should be allowed.
    Other commenters who responded to Issue 25 (Exs. 2-23, 2-36, and 2-
50) stated that more detailed guidance was needed for proper use of 
horizontal lifelines. Also, two commenters (Exs. 2-35 and 2-89) 
asserted that the person designated to supervise work performed under 
proposed paragraph (d)(14) should be a ``competent person.'' OSHA notes 
that a ``competent person'' as defined in Sec. 1926.32(f) has the 
ability to recognize hazards and the authority to have them corrected, 
but does not necessarily have the technical capability to resolve the 
safety issue. Such capability is included in the definition of a 
``qualified'' person as defined in Sec. 1926.32(l). The Agency believes 
that this provision warrants the services of a person who is both 
qualified to design, install and use horizontal lifelines and 
authorized to have the problem corrected. OSHA believes, therefore, 
that the language in the final rule that requires a ``qualified 
person'' with supervisory authority will address the concerns of the 
commenters.
    Paragraph (d)(9) (proposed as paragraphs (d)(13) and (d)(15)) 
requires lanyards and vertical lifelines to have a minimum breaking 
strength of 5,000 pounds (22.2kN). This provision is essentially the 
same as the two separate proposed provisions except that the final 
provisions uses the term ``breaking strength'' instead of the term 
``tensile strength'' used in the proposed provisions. OSHA has made 
this editorial change to clearly indicate the intent of the provision. 
Proposed paragraph (d)(13) also provided that self-retracting lifelines 
and lanyards that limited free-fall to 2 feet or less were required to 
have a tensile strength of 3,000 pounds. That language has been 
relocated to paragraph (d)(12) of the final rule. The SSFI (Ex. 2-89) 
commented that the 5000 lb. tensile strength for vertical lifelines ``* 
* * is not applicable to all situations * * *'' and recommended that 
OSHA require ``* * * lifelines be capable of an anchorage equal to 2 
(two) times the maximum arrest force.'' The SSFI did not specify which 
situations the 5,000 pound requirement was not applicable. OSHA notes 
that the anchorage requirement is discussed under paragraph (d)(15) 
below. Another commenter (Ex. 2-50) recommended that compliance with 
the proposed 5000 pound tensile strength requirement be evaluated using 
Federal Standard 191 Test Method 6015 or 6016. The Agency is not aware 
of any reason to specify the use of the above mentioned test methods, 
nor did the commenter provide any such reasons. Therefore, OSHA has not 
made the suggested change.
    Paragraph (d)(10) (proposed as paragraph (d)(11) prohibits more 
than one employee being attached to any one lifeline, except as 
provided in paragraph (d)(10)(ii). The exception allows two employees 
to be attached to the same lifeline during construction of elevators, 
provided the employees are working atop a false car that is equipped 
with guardrails and the breaking strength of the lifeline has been 
increased to 10,000 pounds [5,000 pounds per worker attached] and all 
other criteria of paragraph (d) for personal fall arrest systems has 
been met. This exception recognizes the potential for a greater hazard 
(entanglement) in the elevator shaft with the additional lifeline.
    There was one comment on this provision. The National Elevator 
Industry, Inc. (NEII) (Ex. 2-11) stated as follows:

    In the Elevator Industry, work in hoistway is performed by a 
team of two employees. This is a relatively small area and work is 
usually performed at the same level from a false car that is 
equipped with guardrails. The Lifeline/Safety Belt system provides 
protection in the event of a catastrophic failure of the false car 
system. Under these circumstances, the Elevator Industry feels that 
if a lifeline had adequate breaking strength for supporting two 
employees then one lifeline would be sufficient. The employees 
working at the same level on a false car that is equipped with 
guardrails would virtually eliminate the chance of one pulling 
another off the false car. The small area of an elevator hoistway 
makes the use of multiple lifelines impractical due to the chances 
for entanglement, etc.

    OSHA has observed the working conditions described above and agrees 
that NEII's recommended alternative measures will provide appropriate 
fall protection for the affected employees. OSHA has incorporated these 
measures into paragraph (d)(10)(ii) of the final rule.
    Paragraph (d)(11) (proposed as paragraph (d)(3)) requires lifelines 
to be protected against being cut or abraded. This provision which is 
identical to the proposed provision, is based on existing 
Sec. 1926.104(e). A commenter, (Ex. 2-89), suggested that the proposed 
provision be reviewed for ``* * * consistency and that the term 
``lifeline'' could be used with another term, i.e., ``dropline * * *'' 
OSHA has eliminated the terms ``dropline'' and ``trolley line'' to 
avoid confusion. The terms vertical lifeline and horizontal lifeline 
are used and both are required by this provision to be protected 
against being cut or abraded. Therefore, OSHA promulgates paragraph 
(d)(11) as proposed.
    Paragraph (d)(12) (proposed as part of paragraph (d)(13)) requires 
that, when in the fully extended position, self-retracting lifelines 
and lanyards which automatically limit free fall distance to 2 feet or 
less be capable of sustaining a minimum tensile load of 3,000 pounds 
(13.3 kN). This provision is essentially the same as the proposed rule 
except that it has been editorially revised to make it clear that the 
3000 pounds is to be determined by applying the load while the lifeline 
or lanyard is in the fully extended position. There were no comments on 
this provision of the proposed rule.
    Paragraph (d)(13) of the final rule requires that, when in the 
fully extended position, self-retracting lifelines and lanyards which 
do not limit free fall to two feet or less, as well as ripstitch, 
tearing and deforming lanyards, be capable of sustaining a minimum 
tensile load of 5,000 pounds (22.2 kN). Proposed paragraph (d)(13) set 
a general requirement for vertical lifelines to have 5,000 pounds 
tensile strength, except where self-retracting lifelines and lanyards 
automatically limited free fall to two feet or less. The other 
provisions of the proposed paragraph have been relocated to paragraphs 
(d)(9) and (d)(12) of the final rule. OSHA is promulgating paragraph 
(d)(13) to maintain the coverage set by the proposed rule. The Agency 
has specifically identified some of the types of lanyards covered by 
this paragraph (i.e. ripstitch, and tearing and deforming lanyards) to 
facilitate compliance.
    Issue #23 of the NPRM solicited comments and suggestions, with 
supporting information, regarding the regulation of self-retracting 
lifelines and lanyards in proposed paragraph (d)(13). In particular, in 
the first part of the issue, OSHA asked if self-retracting lifelines 
and lanyards should be required to meet the minimum load requirement 
with the line or lanyard fully extended. In the second part of the 
issue, OSHA asked whether it should specify the maximum arrest force to 
be transmitted by those devices given the kind of body belt or harness 
used. The response to the second element of Issue #23 is addressed in 
relation to Sec. 1926.502(d) (16) of the final rule, below.
    Some commenters (Exs. 2-35 and 2-36) stated that it was appropriate 
to set 3,000-pound minimum strength for a self- retracting lifeline or 
lanyard that arrested falls within two feet. Another commenter (Ex. 2-
50) supported a requirement for the lines and lanyards to meet minimum 
strength when fully extended.
    The SSFI (Ex. 2-89) commented that the proposed 5,000- pound 
tensile strength requirement is not applicable to all situations and 
that OSHA should revise the provision to require that lifelines be 
capable of an anchorage equal to twice the maximum arrest force.
    Two other commenters (Exs. 2-12 and 2-43) stated that OSHA should 
specify maximum arrest force for self-retracting lifelines and 
lanyards, with an upper limit of 1,125 lbs. The commenters indicated 
that such an upper limit would be easily attainable using available 
equipment and would be consistent with the draft ISO international 
standard.
    OSHA believes, based on the evidence in the record, that the 5,000 
pound requirement is appropriate. No evidence or convincing arguments 
have been presented to the Agency, to date, to demonstrate that this 
requirement should be changed to a lower number, or that there is any 
specific situation where the 5,000 pound requirement is not 
appropriate.
    Paragraph (d)(14), which was not part of the proposed rule, 
requires that ropes and straps (webbing) used in lanyards, lifelines 
and strength components of body belts and body harnesses not be made 
from natural fibers. A commenter (Ex. 2-50) recommended that OSHA 
require the use of synthetic fiber rope in personal fall arrest systems 
because natural fiber rope is not reliable or predictable as it ages 
during use and because the strength deterioration of natural fiber rope 
is not obvious or always detectable during inspection. In addition, a 
National Bureau of Standards (NBS) report (Ex. 3-8) advises against the 
use of natural fiber rope due to unpredictable deterioration. OSHA 
agrees that natural fiber rope would not be sufficiently reliable for 
use in a personal fall arrest system and has revised the proposed rule 
accordingly. OSHA has already adopted this approach in Sec. 1910.66, 
Appendix C, Section I--Mandatory, and also has proposed to adopt it in 
proposed Sec. 1910.128(c)(12) (55 FR 13436, April 10, 1990).
    Paragraph (d)(15) (proposed as paragraph (d)(12)) requires that 
anchorages used for the attachment of personal fall arrest equipment be 
capable of supporting at least 5,000 pounds (22.2 kN) per employee 
attached or the anchorage must be designed, installed and used under 
the supervision of a qualified person and as part of a complete 
personal fall arrest system which maintains a safety factor of at least 
two. This provision differs from both the proposed provision, which 
required that anchorages be able to support at least twice the 
potential impact load of an employee's fall, and existing 
Sec. 1926.104(b), which requires anchorages to be capable of supporting 
a minimum dead weight of 5,400 pounds. OSHA proposed to replace the 
existing provision, which was based on the rated strength of manila 
rope, and was not based on the actual load the anchor must support when 
an employee falls. The proposed provision was more performance-oriented 
and addressed the actual forces involved.
    Issue #26 of the proposed rule requested public comment on the 
applicability of the fall protection provisions of Appendix D in the 
proposed rule for powered platforms (50 FR 2890, January 22, 1985) to 
the construction industry. Some commenters (Exs. 2-12, 2-36, 2-41, 2-43 
and 2-45) recommended that OSHA promulgate paragraph (d)(12) as 
proposed. Other commenters (Ex. 2-23 and 2-35) suggested that OSHA 
revise proposed paragraph (d)(12) to require that the anchorage sustain 
twice the potential load or 5,000 pounds, whichever is greater. Those 
commenters expressed concern that, applying the proposed rule, an 
inexperienced rigger would simply double the weight of the affected 
employee and think that the resulting system is safe. They also noted 
that OSHA could set 3,600 pounds as the minimum, because proposed 
paragraph (d)(12) limited impact load to 1,800 pounds, but they thought 
that would make it difficult for OSHA to justify the 5,000 pound load 
requirements elsewhere in the proposed rule. Another commenter (Ex. 2-
50) recommended that the strength of anchorages be either at least 
twice the potential dynamic loading force if certified by a qualified 
person, or 5,000 pounds when not so certified. In addition, comments on 
the proposed rule for powered platforms (Ex. 3-13) indicated a need to 
set a minimum strength requirement as well as to allow employers the 
option of designing, installing and using a complete system which 
maintains a safety factor of two.
    OSHA agrees with the commenter who suggested that anchorages be 
required to sustain a 5,000 pound load when they have not been 
certified by a qualified person as able to sustain twice the potential 
load. The Agency believes that only anchorages that are certified by a 
qualified person can be relied upon to provide adequate protection at 
the lower strength level. On the other hand, when not so certified OSHA 
believes it is appropriate for the anchorage to sustain at least 5,000 
pounds. OSHA has already adopted this approach in Sec. 1910.66, 
Appendix C, Section I--Mandatory, and has proposed to adopt it in 
proposed Sec. 1910.128(c)(10) (55 FR 13436, April 10, 1990).
    Paragraph (d)(16) (proposed as paragraphs (d)(4), (d)(5) and 
(d)(6)) consolidates the performance criteria for personal fall arrest 
systems. Paragraph (d)(16)(i) limits the maximum arresting forces on an 
employee to 900 pounds when a body belt is used. Paragraph (d)(16)(ii) 
limits the maximum arresting forces on an employee to 1,800 pounds when 
a body harness is used. As discussed in relation to the introductory 
text of paragraph (d), above, the Agency has decided that body belts 
must be phased out from use in personal fall arrest systems because 
employees wearing them have been seriously injured by the impact loads 
transmitted and by the pressures imposed while suspended after fall 
arrest. Paragraphs (d)(16)(i) and (d)(16)(ii) reflect the Agency's 
determination that fall arrest systems which use body belts up to the 
time the prohibition takes effect must minimize the related hazards by 
limiting the impact load to half that allowed when body harnesses are 
worn.
    Proposed paragraph (d)(6) required that body belt/harness systems 
not produce an arresting force on an employee of more than 10 times the 
employee's weight or 1,800 pounds, whichever was less. Issue 14 of the 
proposed rule asked if the proposed 1,800-pound limit was appropriate 
for body belts. The comments on proposed Appendix D of the powered 
platform rulemaking (Ex. 3-13), discussed in detail at 54 FR 31449-
31451, July 28, 1989), which supported an identical requirement in the 
general industry rule, were considered by the Agency as support for the 
provisions of subpart M to limit the maximum arrest force for body 
belts at 900 pounds and to maintain the limit for body harnesses at 
1800 pounds. In comments addressing Issue 14 directly, two commenters 
on proposed subpart M (Exs. 2-36 and 2-50) supported a 900-pound limit. 
The R&TC (Ex. 2-36) stated ``[b]elts should have a nine-hundred pound, 
or lower, limit because no human can tolerate a live demonstration of 
an eighteen-hundred pound fall arrest in a belt. That rulemaking 
participant also testified (Tr. 2-17 to 2-19, 3-23-88) regarding 
specific incidents which indicated the advantages of using body 
harnesses instead of body belts. Several commenters (Exs. 2-12, 2-19, 
2-23, 2-43 and 2-140) stated that it was inappropriate to distinguish 
between body belts and body harnesses.
    OSHA has determined that the hazards posed by body belts, as 
discussed earlier, necessitate setting a lower impact load limit for 
systems which use them, until January 1, 1998, at which time, as 
discussed above, body belts will be prohibited for use as part of a 
personal fall arrest system. Therefore, the Agency is promulgating 
paragraphs (d)(16)(i) and (d)(16)(ii).
    Paragraph (d)(16)(iii) requires that personal fall arrest systems 
be rigged so that an employee can neither free fall more than six feet 
nor contact a lower level. Paragraph (d)(16)(iv) requires that after 
the free fall distance, the personal fall arrest system must bring an 
employee to a complete stop and limit maximum deceleration distance an 
employee travels to 3.5 feet. These two paragraphs are essentially 
identical to proposed paragraphs (d)(4) and (d)(5).
    Issue 14 of the proposal asked if OSHA should limit the free fall 
distance to two feet, rather than six feet, where a body belt was being 
used. Several commenters (Exs. 2-12, 2-19, 2-23, 2-43 and 2-140) 
supported proposed paragraph (d)(4), stating that it was inappropriate 
to distinguish between body belts and body harnesses. In particular, a 
commenter (Ex. 2-23) stated ``[T]he maximum 6 foot free fall limitation 
is acceptable for body belts, and no 2 foot limit should be imposed.'' 
Other commenters (Exs. 2-36 and 2-50) stated that OSHA should limit the 
free fall distance to two feet where body belts are used, citing 
Australian and New Zealand standards. One commenter (Ex. 2-36) stated 
``[r]etracting lifelines can be considered for continued belt usage by 
employers in the U.S.A., since free fall is usually less than two feet 
and self-recovery likelihood is excellent.''
    Other commenters on these provisions noted some confusion between 
the two. For example, one commenter (Ex. 2-20) stated that proposed 
paragraphs (d)(4) and (d)(5) could be ``misinterpreted'' and suggested 
``modification of the wording.'' Another commenter (Ex. 2-23) stated 
that OSHA should add a sentence to the proposed paragraph (d)(4) saying 
``[t]he rigger must consider total fall distance and thus include the 
lifeline elongation.'' and ``[t]he present wording of this section is 
very confusing, so we suggest more precise wording to explain that the 
42-inch limit is for the deceleration device.'' In addition, the 
comments on proposed Appendix D of the powered platform rulemaking (Ex. 
3-13), discussed in detail (54 FR 31450, July 28, 1989), indicated 
concern regarding the distinction between deceleration distance and 
free fall distance.
    The Agency notes that the final rule defines the terms 
``Deceleration distance'' and ``Free fall distance'' (discussed above 
in relation to Sec. 1926.500(b)) and believes that the definitions make 
it clear when free fall begins and ends and how to determine 
deceleration distance. OSHA has already adopted this approach in 
Sec. 1910.66, Appendix C, Section I--Mandatory, and has proposed to 
adopt it in proposed Sec. 1910.129(b)(1)(iii) (55 FR 13436, April 10, 
1990).
    Paragraph (d)(16)(v), which was not part of the proposed rule, 
requires that the personal fall arrest system have sufficient strength 
to withstand twice the potential impact energy of an employee free 
falling a distance of 6 feet, or the free fall distance permitted by 
the system, whichever is less. The comments on proposed Appendix D of 
the powered platform rulemaking (Ex. 3-13), discussed in detail (54 FR 
31450, July 28, 1989), supported a requirement for personal fall arrest 
systems to be designed with a safety factor of at least two. The Agency 
has specified that the ability of a system to satisfy this requirement 
must be assessed based on a fall distance of 6 feet or the distance 
allowed by the system, whichever is less, so that this provision 
coordinates with paragraph (d)(16)(iii), above. OSHA has already 
adopted this approach in Sec. 1910.66, Appendix C, Section I-Mandatory, 
and has proposed to adopt it in proposed Sec. 1910.129(b)(1)(iv) (55 FR 
13436, April 10, 1990).
    OSHA has added a note to paragraph (d)(16) which references the 
criteria and protocols in Sec. 1910.66, Non-mandatory Appendix C, as 
examples of means by which employers can determine if their personal 
fall arrest systems comply with the standard. The note also indicates 
that systems used by employees having a combined tool and body weight 
of 310 pounds or more would need to modify the criteria and protocols 
to account for the greater weight, in order to apply Appendix C. OSHA 
has already adopted this approach in Sec. 1910.66, Appendix C, Section 
I-Mandatory, and has proposed to adopt it in proposed 
Sec. 1910.129(b)(2) (55 FR 13436, April 10, 1990).
    Paragraph (d)(17) (proposed as paragraph (d)(7) requires that 
personal fall arrest systems be worn so that the attachment point for 
body belts is located in the center of the wearer's back, and that the 
attachment point for body harnesses is located either in the center of 
the wearer's back near shoulder level, or above the wearer's head. The 
proposed rule was essentially identical. There were no comments on the 
substance of the provision and OSHA promulgates paragraph (d)(17) as 
editorially revised. The AGC (Exs. 2-16, 2-47, 2-92 and 2-103) 
commented as follows:

    Proper positioning of the lanyard or deceleration device is 
crucial for the prevention of injuries in a fall situation. 
Construction employers have emphasized to employees this aspect of 
body belt usage. However, AGC believes that mandated as such in the 
proposed rule is inappropriate and unworkable. Subsequent to 
required training, employers cannot be responsible for each 
employees positioning of this type device.

    In response, OSHA again notes that under the OSH Act, employers 
bear direct responsibility for compliance with OSHA regulations. 
Accordingly, the Agency has not revised the proposed rule based on the 
AGC comment. OSHA has already adopted this approach in Sec. 1910.66, 
Appendix C, Section I--Mandatory, and has proposed to adopt it in 
proposed Sec. 1910.129(c)(4) (55 FR 13436, April 10, 1990).
    Paragraph (d)(18) (proposed as paragraph (d)(1)) requires that body 
belts, harnesses, and components be used only for employee fall 
protection or positioning. This means that those systems or components 
may not be used as material or equipment hoist slings, bundle ties, or 
for other such purposes. This is substantively the same requirement as 
the proposed provision and as the existing provision in 
Sec. 1926.104(a). One commenter (Ex. 2-23) stated that OSHA should also 
indicate in this provision that body belt and harness systems can be 
used ``* * * for work positioning and retrieval as well * * *'' Also, a 
commenter (Ex. 2-35) stated ``I believe the purpose of this requirement 
is to prevent the equipment being used for such things as material 
handling. But you have never defined a positioning belt/harness system, 
only a `personal fall arrest system.' Therefore, this provision 
prevents the use of belts for positioning or such things as controlled 
descent.''
    The SSFI (Ex. 2-89) said they felt clarification was needed for the 
sentence indicating how body belt/harness systems could be utilized. 
They recommended that the body belt/harness system could be used for 
fall and/or work positioning.
    OSHA acknowledges that the proposed provision could have been 
construed to prohibit the use of body belts or body harnesses in 
positioning device systems. OSHA intended simply to prevent the use of 
such systems for material hoisting or related purposes. The Agency is 
concerned that a fall protection system that had been used to hoist 
material would then be issued to an employee as a fall protection 
system. OSHA has revised the provision to indicate clearly its intent 
that components of fall arrest and positioning device systems are only 
to be used for those purposes. OSHA has already adopted this approach 
in Sec. 1910.66, Appendix C, Section I--Mandatory, and has proposed to 
adopt it in proposed Sec. 1910.128(c)(14) (55 FR 13436, April 10, 
1990). The Agency has also added the identical language to 
Sec. 1926.502(e) of the final rule as paragraph (e)(10), to facilitate 
compliance.
    Paragraph (d)(19) (proposed as paragraph (d)(2)) requires that 
personal fall arrest systems or components of subject to impact loading 
(as distinguished from static load testing) be immediately removed from 
service, and prohibits subsequent use unless inspected by a competent 
person who determines the system or component to be undamaged and 
suitable for reuse. This is essential the same as the proposed 
requirement and the existing requirement in Sec. 1926.104(a) except the 
existing provision prohibits any further use of belts for employee 
protection. In the proposed rule, OSHA explained that impact loading 
did not necessarily adversely affect the integrity of a body belt/
harness system. OSHA further explained that a relatively short fall of 
one foot may leave the belt/harness system undamaged; however, a long 
fall of six feet or greater probably would destroy or seriously damage 
the belt or harness. There are many factors, such as the employee's 
weight and the type of deceleration device used, which can affect a 
system's potential capacity for reuse as fall protection. Therefore, a 
blanket prohibition of reuse after any impact loading is not 
appropriate.
    There were two comments on the provision. One commenter (Ex. 2-15) 
stated ``[n]of only should the components be removed from service, but 
they should be marked as ``defective'' to ensure the equipment won't be 
inadvertently used again until it is found not to be defective or made 
to be no longer defective by a competent person.''
    The other commenter (Ex. 2-23) suggested that OSHA revise the 
proposed provision to rule out reuse after an impact load.
    OSHA believes that it is unnecessary to mandate that equipment be 
marked or labelled ``defective'' and that it is sufficient to remove 
equipment from service so that it cannot be used, at least until its 
strength has been evaluated. The Agency does not believe it necessary 
to specify the manner in which employers choose to identify components 
that need to be evaluated before they can be reused. The Agency is 
concerned solely that the method chosen effectively prevent the reuse 
of equipment that has not been cleared for reuse. In addition, OSHA 
believes that an absolute ban on the reuse of fall arrest system 
components would be unnecessary because such equipment may still have 
the strength needed for continued use. The employer, in turn, needs to 
ensure that procedures for inspection and evaluation of equipment will 
prevent the reuse of damaged components. OSHA has already adopted this 
approach in Sec. 1910.66, Appendix C, Section I-Mandatory, and has 
proposed to adopt it in proposed Sec. 1910.128(c)(15) (55 FR 13436, 
April 10, 1990).
    Several commenters on proposed Appendix D of the powered platform 
rulemaking (Ex. 3-13), discussed in detail at 54 FR 31452, expressed 
concern regarding the need for prompt rescue after fall arrest, 
especially when body belts are being used, because prolonged suspension 
may be harmful to employees. OSHA agrees with these comments and has 
added paragraph (d)(20) to the final rule. Under this provision, the 
employer is required to evaluate the potential for fall arrest and to 
determine which rescue strategy will be used to rescue a suspended 
employee safely. When it is not possible to evaluate the self-rescue 
capacity of employees in advance, prudent employers should assume that 
employees will need rescue assistance and, accordingly, be prepared to 
offer it. See paragraph (f) Rescue considerations of Appendix C, Part 
II, for guidance in meeting the requirements of this provision. OSHA 
has already adopted this approach in Sec. 1910.66, Appendix C, Section 
I-Mandatory, and has proposed to adopt it in proposed 
Sec. 1910.129(c)(6) (55 FR 13436, April 10, 1990).
    Paragraph (d)(21) (proposed as paragraph (d)(20)) requires that 
personal fall arrest systems be inspected prior to each use for damage 
and deterioration, and that defective components be removed from 
service. This provision is essentially identical to the proposed 
provision in Sec. 1926.502(d)(20).
    OSHA raised Issues #9 and #17 in the proposal to request public 
comment regarding the frequency of inspection and whether or not more 
definitive inspection criteria were needed for determining when 
personal fall arrest systems (or positioning device systems, as 
regulated in paragraph (e)(5), below) are no longer suitable for use. 
OSHA also asked commenters what inspection criteria should be 
specified.
    A commenter (Ex. 2-23) suggested that OSHA delete the words ``if 
their strength or function has been adversely affected.'' OSHA agrees 
that deleting those words will make the rule easier to understand, 
i.e., employers would simply remove components that are defective, in 
that they do not meet the criteria set in paragraph (d), without having 
to make a specific determination about strength or function.
    The majority of the commenters thought the criteria provided in the 
standard were sufficient as proposed (Exs. 2-12, 2-19, 2-23, 2-43, and 
2-45). However, several commenters suggested that additional 
information should be conveyed to employees through training programs, 
by following manufacturer's specifications, or by OSHA in the form of 
guidelines (Exs. 2-16, 2-23, 2-35, 2-36, 2-41, 2-47 and 2-92). OSHA 
observes that such training is required under new Sec. 1926.503, 
discussed below. The ISEA, the ANSI Z359 Committee and the Roofers 
Union (Exs. 2-23, 2-50 and 2- 99) supported the proposed requirement 
for inspection prior to each use.
    The AGC (Exs. 2-16, 2-47 and 2-92) agreed that inspections were 
needed and noted, as they have with other provisions (see discussion at 
paragraph (d)(17) of the final rule above, that employees, rather than 
employers, should be held responsible for ensuring that fall protection 
equipment is functioning properly prior to each use. Other commenters 
(Exs. 2-41, 2-42 and 2-51) supported the AGC position. In that regard, 
OSHA again observes that under the OSH Act, employers bear direct 
responsibility for compliance with OSHA regulations.
    The GLFEA and the BCMALU (Exs. 2-19 and 2-46) thought inspection 
should be weekly rather than prior to each use. The GLFEA supported its 
position with the statement that ``A more frequent schedule does not 
enhance the safety of the employees.''
    Essentially, there was no objection to the substance of the rule, 
only disagreement on the frequency of inspection. OSHA believes it is 
critical to inspect equipment before each use; otherwise, employees may 
use defective equipment which could result in loss of life in the event 
of a fall. Therefore, OSHA has not reduced the frequency of inspection 
and has determined that the provision, as proposed, is appropriate. 
Further information on inspection criteria has been provided in 
paragraph (g) Inspection considerations in Part II of Appendix C 
relating to Sec. 1926.502(d)--Personal Fall Arrest Systems. OSHA also 
notes that this provision is consistent with the inspection 
requirements for personal fall arrest systems in the powered platforms 
standard, Sec. 1910.66.
    Paragraph (d)(22) requires that body belts be at least one and 
five-eighths (1\5/8\) inches (4.1 cm) wide. This provision is identical 
to the provision in proposed paragraph (d)(8). There were no comments 
on the proposed provision and OSHA promulgates paragraph (d)(23) as 
proposed.
    Paragraph (d)(23) (proposed as paragraph (d)(21)) prohibits the 
attachment of personal fall arrest systems to hoists or guardrail 
systems, except where otherwise provided in part 1926. This requirement 
is essentially the same as existing Sec. 1926.500(g)(5)(iv), which 
applies only to built-up roofing operations on low-pitched roofs, and 
does not include the guardrail restriction. OSHA proposed to extend the 
rule to prohibit using any hoist or guardrail system as an anchorage 
attachment point. Additionally, the existing rule in Sec. 1926.104(b) 
specifies minimum anchorage requirements for body belts.
    Neither hoists nor guardrail systems are designed as anchorages for 
personal fall arrest systems since they are not built to withstand the 
impact forces generated by a fall. Therefore, in the interest of 
employee safety, OSHA is prohibiting the use of hoists and guardrails 
as attachment points.
    There were two comments on the proposed provision. The ISEA (Ex. 2-
23) noted that the provision ``* * * would eliminate the common 
practice of workers attaching to a `man basket' while riding in it.'' 
OSHA notes that the more specific rule Sec. 1926.550(g)(6)(vii), in the 
crane safety standards, regulates ``man baskets.'' The SSFI (Ex. 2-89) 
recommended that the provision be changed to indicate that a body belt/
harness system should never be attached to any guardrail system, not 
just those at hoist areas. OSHA agrees that the reasons workers should 
not attach to guardrail systems or hoists at hoist areas as for any 
other hoist or guardrail, regardless of where it is located and 
therefore, OSHA has revised the language of provision to make that 
clear.
    Paragraph (d)(24) (proposed as paragraph (d)(22)) specifies that 
personal fall arrest systems used at hoist areas are to be rigged to 
allow the movement of employees only as far as the edge of the walking/
working surface. This is the same requirement proposed at 
Sec. 1926.502(d)(22). It is essentially the same as existing 
Sec. 1926.500(g)(5)(v), which applies only to built-up roofing 
operations on low-pitched roofs. OSHA proposed to extend the 
requirement to cover all hoist areas. The limitation on movement when 
wearing a personal fall arrest system is made because of the employees' 
tendency to lean out over the edge at hoist areas. There were no 
comments on this provision.
    Paragraph (e)--Positioning device systems. This paragraph sets the 
minimum performance criteria for ``positioning devices,'' which are 
systems similar to personal fall arrest systems and which can be 
comprised of many of the same components. The significant difference is 
that personal fall arrest systems are used to arrest falls, whereas 
employees use positioning devices so they can maintain a leaning 
position without using their hands while working on vertical surfaces. 
For example, these devices may be used during the placement of 
reinforcing bars in the vertical face of a wall under construction. The 
employees often stand on bars already in place and must lean backward, 
similar to a lineman on a telephone pole, to place additional bars. The 
positioning device allows this to be done without the employees having 
to use their hands to maintain position.
    Several provisions of proposed Sec. 1926.502(d) have been 
incorporated into final rule paragraph (e). In issuing the proposal, 
OSHA considered the pertinent paragraph (d) requirements to cover both 
personal fall arrest systems and positioning device systems. The Agency 
has subsequently concluded that placing those provisions directly in 
paragraph (e) will best assure that employers who have employees use 
positioning device systems have clear direction on safe use of those 
systems. OSHA has specifically identified the added provisions below.
    A general comment relating to proposed Sec. 1926.502(e) came from 
CAL/OSHA (Ex. 2-15) who commented that components of positioning device 
systems should be permanently marked to indicate that they meet the 
applicable standards. CAL/OSHA also recommended that equipment covered 
by paragraph (d) personal fall arrest systems be permanently marked. As 
with paragraph (d), OSHA does not believe that requiring the marking of 
positioning device systems is necessary for employee protection in this 
standard. The criteria set forth in paragraph (e) must be met, in any 
event, in order to assure that the equipment protects the employee. In 
addition, based on the response to Issue #18, discussed above in 
relation to Sec. 1926.502(d)(4) of the final rule, OSHA believes that 
equipment manufacturers are already voluntarily marking their products. 
Accordingly, any benefit resulting from addition of such a requirement 
would be minimal. Therefore, OSHA has not added the suggested language.
    Paragraph (e)(1) requires that positioning device systems be rigged 
so that an employee cannot free fall more than 2 feet. The proposed 
rule was identical. OSHA set this distance less than the 6 foot free 
fall distance set in paragraph (d)(16) for personal fall arrest systems 
because lanyards used with positioning devices usually do not stretch 
under fall impact loading and deceleration devices normally are not 
used to reduce the forces incurred during a fall. There were no 
comments on paragraph (e)(1).
    Paragraph (e)(2), proposed as paragraph (e)(3), requires that 
positioning devices be secured to an anchorage capable of supporting at 
least twice the potential impact load of an employee's fall or 3,000 
pounds, whichever is greater. This provision differs from OSHA's 
proposed provision by the addition of the language ``or 3,000 pounds, 
whichever is greater.''
    There were several comments on the proposed provision. The ISEA and 
MSA (Exs. 2-23 and 2-35) suggested that OSHA add language to the 
provision to make it consistent with the strength requirement proposed 
in paragraph (d)(13) of this section for self-retracting lifelines and 
lanyards that limit free fall to 2 feet. OSHA agrees that adding the 
suggested language will provide employers with useful and consistent 
guidance, and has revised the provision accordingly.
    NIOSH (Ex. 2-33) stated that the proposed provision placed 
responsibility on the employee to determine the proper anchorage point, 
and that the provision should be rewritten to specify that a supervisor 
or site safety officer has the responsibility. In response, OSHA notes 
that many provisions in OSHA standards require direct employee action 
in order to achieve compliance. Regardless of who performs the 
necessary duties under the standard, the employer has direct 
responsibility to provide a safe workplace by complying with the OSH 
Act and with the pertinent regulations, and it is the employer who will 
be cited should a violation occur. Accordingly, the Agency does not 
believe that specifying the personnel responsible for identifying 
anchorage points is necessary for employee protection. Therefore, OSHA 
has not made the suggested change.
    Paragraph (e)(3) requires connectors to be dropped forged, pressed 
or formed steel, or made of equivalent materials. This is a new 
requirement and has been added to maintain consistency with final rule 
Sec. 1926.502(d)(1) which addresses connectors used as part of a 
personal fall arrest system. This provision and its rationale are 
identical to those for paragraph (d)(1) of this section, above.
    Final rule paragraph (e)(4), proposed as paragraph (e)(2), requires 
that connectors be of a corrosion-resistant finish and that all 
surfaces and edges be smooth to prevent damage to interfacing parts of 
the systems. OSHA solicited comments on the need for quantification of 
corrosion resistance requirements in Issue #22 of the proposal. The 
response to that issue is discussed in relation to paragraph (d)(2), 
above. As with paragraph (d)(2), the Agency has decided that additional 
corrosion resistance testing requirements are also not needed in 
paragraph (e)(4). OSHA has editorially revised the proposed provision 
so that it is identical to paragraph (d)(2) of this section which 
contains the same requirement. Specifically, the words ``attached belt 
or connecting assembly'' has been revised to read ``interfacing parts 
of the system.'' This is the same language that OSHA used in its final 
rule for Powered Platforms for Building Maintenance [54 FR 31470, July 
28, 1989] and in proposed Sec. 1910.128(c)(2) [55 FR 13436, April 10, 
1990].
     Final rule paragraph (e)(5), proposed as paragraph (e)(4), 
requires that connecting assemblies (which are dee rings, snaphooks, 
lanyards and other components of the positioning device system) have a 
minimum breaking strength of 5,000 pounds. This provision is identical 
to the proposed rule. There were two comments on the proposed 
provision.
    The MSA (Ex. 2-35) commented that this provision should be changed 
to require a minimum breaking strength of 3,000 pounds, to be 
consistent with provision (e)(3) above. The SSFI (Ex. 2-89) objected to 
OSHA's use of 5,000 pounds because, as they have expressed earlier 
under paragraph (d), they believe lifelines should be capable of 
anchorage equal to two times the maximum arrest force and all 
requirements therefore should be consistent with that capability.
    OSHA observes that this provision is consistent with other similar 
provisions in Sec. 1926.502(d) which prescribe the breaking strength of 
lanyards, connectors, snaphooks, dee-rings, etc. While a breaking 
strength of 3000 pounds might be adequate if the fall was limited as it 
should be when a positioning device system is used, 3000 pounds would 
not be adequate if the connecting assembly was inadvertently used as 
part of a fall arrest system. Since there is no way to determine by 
simple observation whether the connecting assembly has a breaking 
strength of 3000 pounds or 5000 pounds, users of connecting assemblies 
could easily interchange components. Therefore, in the interest of 
worker safety, it is appropriate that OSHA require all connecting 
assemblies to have the same minimum breaking strength. In this way, if 
the connecting assembly is used as part of a personal fall arrest 
system, the strength will be adequate and the connecting assembly will 
not break.
    Final rule paragraph (e)(6), like final rule paragraph (d)(4), 
requires that dee-rings and snaphooks be proof-tested to a minimum 
tensile load of 3600 pounds without cracking, breaking, or taking 
permanent deformation. A complete discussion of this provision can be 
found at Sec. 1926.502(d)(4) above. This new provision, which was not 
proposed, has been added to facilitate safe use of positioning devices.
    Final rule paragraph (e)(7), like final rule paragraph (d)(5), 
requires that snaphooks be sized to be compatible with the member to 
which they are connected or be of a locking type designed to prevent 
disengagement of the snaphook and, that after December 31, 1997, only 
locking type snaphooks can be used in positioning device systems. In 
addition, final rule paragraph (e)(8), like final rule paragraph 
(d)(6), provides that for certain specified connections, only locking 
snaphooks designed for those connections can be used.
    As discussed above in reference to paragraphs (d)(5) and (d)(6), 
OSHA solicited information in Issue 16 of the proposal regarding the 
need to require locking snap-hooks in personal fall arrest systems. The 
same concerns apply to the use of snap-hooks in positioning device 
systems. Therefore, the language of paragraph (d)(5) and (d)(6) of the 
final rule has been adopted as paragraphs (e)(7) and (e)(8) to ensure 
that only locking snaphooks are used and then only those designed for 
certain connections be used in the specified circumstances.
    The SSFI (Ex. 2-89) noted that proposed Sec. 1926.502(e) had not 
set forth requirements for snaphooks or diameters of attachments to 
prevent ``roll-out'' and suggested that OSHA include them in the final 
rule, referencing its comments on Issue #16. As stated above, OSHA 
agrees that employees need the protection afforded by the snaphook 
requirements for both personal fall arrest systems and positioning 
device systems. OSHA also notes that compliance with this requirement 
will not impose increased burdens on employers, since all snaphooks 
will be subject to the same criteria whether they are used as part of a 
personal fall arrest system or part of positioning device system. OSHA 
also notes that these provisions on snaphooks are consistent with 
OSHA's final rule for Powered Platforms for Building Maintenance [54 FR 
31471, July 28, 1989] and proposed Sec. 1920.129(c)(1) [55 FR 13437, 
April 10, 1990].
    Final rule paragraph (e)(9), proposed as paragraph (e)(5), requires 
that positioning device systems be inspected prior to each use for 
damage and deterioration and that defective components be removed from 
service. This provision differs from the proposed provision, in that 
the phrase ``if the strength or function has been adversely affected'' 
has been deleted. As discussed in reference to final rule 
Sec. 1926.502(d)(21), Issue #17 raised questions regarding the need for 
more specific inspection criteria.
    The ISEA (Ex. 2-23) suggested that OSHA delete the words ``if their 
strength or function has been adversely affected.'' The implication was 
that if these words were deleted, the rule would be easier to 
understand, i.e., employers would simply remove components that were 
defective without having to make some determination about strength or 
function. As with Sec. 1926.502(d)(21) of the final rule, discussed 
above, OSHA agrees that deleting those words would make the rule easier 
to understand. Employers will simply remove components that are 
defective, in that they do not meet the criteria of paragraph (e), 
without having to make a specific determination about strength or 
function.
    OSHA received several comments in response to Issue #17. As noted 
in regard to paragraph (d)(21), above, the response to Issue #17 
regarding positioning device systems was the same as that regarding 
personal fall arrest systems.
    After evaluation of the pertinent record materials, OSHA has 
determined that further information on the employer's inspection of 
positioning device systems should be provided in an appendix. 
Therefore, OSHA has included a specific paragraph on inspection 
considerations in the Non- mandatory Appendix D to subpart M to address 
the inspection requirements in Sec. 1926.502(e).
    Final rule paragraph (e)(10), like final rule paragraph (d)(18), 
requires that body belts, harnesses, and components be used only for 
employee fall protection or positioning and not to hoist materials. 
This is a new provision and has been added to maintain consistency and 
facilitate compliance. Paragraph (e)(10) has been added for the same 
reasons discussed above in relation to paragraph (d)(18).
    Paragraph (f)--Warning line systems. This paragraph, which sets the 
same requirements as in the proposed rule and in existing 
Secs. 1926.500(g)(3)(i), (ii), and (iii), provides the criteria for use 
of a warning line system. OSHA notes that this paragraph is also 
consistent with proposed Sec. 1910.28(d), Designated areas, which would 
regulate analogous General Industry situations [44 FR 13402, April 10, 
1990]. The basis for the existing requirements was discussed in detail 
in the preamble of the final rule for the Guarding of Low-Pitched-Roof-
Perimeters During the Performance of Built-Up Roofing Work [45 FR 
75618, November 14, 1980]. In brief, the Agency permitted the use of 
warning lines, under certain conditions, to warn employees that they 
were approaching an unprotected edge. The warning line system was 
permitted when work conditions made it impossible to use conventional 
fall protection systems.
    One commenter, CAL/OSHA (Ex. 2-15), stated that warning line 
components should be marked to ensure compliance with the standard. As 
discussed above, CAL/OSHA also advocated marking personal fall arrest 
system components and positioning device system components. As with the 
other proposed paragraphs, OSHA has determined that such a requirement 
is not necessary for employee safety. However, employers are 
responsible for ensuring that rope, wire, or chains used for warning 
lines comply with the strength requirements of paragraph (f). OSHA's 
position is that it is compliance with the substantive provisions of 
paragraph (f), not the act of marking equipment, that improves employee 
protection. Therefore, OSHA has not made the suggested change.
    In Issue #10 of the NPRM, OSHA noted that the term ``mechanical 
equipment'' was used to describe the type of equipment addressed in the 
provisions of proposed Sec. 1926.502(f) which related to built-up 
roofing work. The proposed definition of ``mechanical equipment'' 
provided that wheelbarrows and mopcarts would not be considered 
``mechanical equipment,'' continuing the approach taken by existing 
Sec. 1926.500(g); that is, that these two types of equipment do not 
require employees to move backward when using them and, therefore, they 
should not be considered ``mechanical equipment'' for the purpose of 
determining the location of the warning line. Issue #10 asked if 
mopcarts and wheelbarrows should remain the only equipment not 
considered ``mechanical equipment'' for the purpose of the provisions 
of paragraphs (f)(1)(i) and (ii).
    In response to Issue #10, three commenters recommended that the 
provision stay as proposed (Exs. 2-12, 2-43 and 2-99). The ACCSH 
recommended that no additional equipment be exempted from the 
provision. (Tr. 6/10/87; pp. 131-132)
    After evaluation of the record on this issue, OSHA has determined 
that wheelbarrows and mopcarts will remain outside the definition of 
``mechanical equipment,'' because no other equipment that merits 
exclusion from the definition has been identified.
    Based on the rulemaking record, OSHA has determined that the 
provisions of paragraph (f) are appropriate as proposed, except that 
the term ``built-up'' which was used in proposed paragraph (f)(3) have 
been removed because the provision is no longer exclusive to built-up 
roofing work, but applies to all roofing work on low-sloped roofs. See 
change made in the definitions section (Sec. 1926.500) and under 
Sec. 1926.501(b)(10).
    Paragraph (g)--Controlled access zones. This paragraph sets minimum 
performance criteria for controlled access zones (CAZ). In the 
introductory text of paragraph (g), OSHA reminds employers that CAZ may 
only be used where employees are performing overhand bricklaying and 
related work or work under a fall protection plan, as provided by 
Secs. 1926.501(b)(2), (b)(9), (b)(12), and (b)(13).
    OSHA proposed the use of controlled access zones as a way to limit 
the number of workers that would be exposed to the hazard of falling 
from unprotected sides or edges at those locations where the use of 
conventional fall protection systems is infeasible or creates a greater 
hazard. The only work situation where use of a CAZ is specifically 
permitted instead of conventional fall protection systems is where 
overhand bricklaying operations are taking place. However, employers 
who develop a fall protection plan under Sec. 1926.501(b)(2), (b)(12), 
or (b)(13), will also be required to establish controlled access zones.
    Employers engaged in overhand bricklaying work may use a CAZ as 
long as the employee does not have to reach more than 10 inches below 
the walking/working level to do the work. Employers engaged in leading 
edge work, precast concrete erection work, or residential construction 
work who demonstrate infeasibility or greater hazard with the use of 
conventional fall protection systems will be required to develop and 
implement a fall protection plan which meets the requirements of 
paragraph (k). Paragraph (k)(7) requires the employer to establish a 
CAZ which meets the requirements of this paragraph (g).
    In general, a controlled access zone is formed by erecting a line 
or lines--referred to as control lines--to restrict access to an area 
or to define the area in which employees will work without conventional 
fall protection. Sometimes only one line will be needed to define the 
area. The control line warns the employee that access to the CAZ is 
limited to authorized personnel. The line also designates the area 
where conventional fall protection systems are not in use.
    As discussed in Sec. 1926.500(b), Definitions, the Mason 
Contractors Association of America (MCAA) (Ex. 2-95) suggested that 
OSHA change the name for the zone from ``control zone'' to ``Controlled 
Access Zone (CAZ).'' MCAA also suggested that OSHA provide diagrams of 
the zone so that the provisions of the control zone section could be 
more clearly understood. As discussed in the definitions section of 
this final rule, OSHA agrees with the MCAA that the revised term--
Controlled Access Zone--more clearly describes the function of the zone 
by indicating that access to the zone is being controlled. OSHA has 
removed portions of the proposed provisions that were confusing and 
therefore is not providing diagrams.
    Paragraph (g)(1) sets the distance from an unprotected side or edge 
that control zone lines are to be erected when leading edge operations 
or other activities are being performed and controlled access zones are 
permitted. When control lines are used, they shall be erected no closer 
than 6 feet nor farther than 25 feet away from the leading edge or 
unprotected edge. An exception is provided for the erection of precast 
concrete members, in which case, the control line must be no closer 
than 6 feet nor farther than one-half the size of the precast member 
being erected, to a maximum of 60 feet. This exception is being made 
for precast concrete erection because it is sometimes necessary to 
``turn'' a precast member which may be as long as 120 feet. If the 
control lines are too close, they could become entangled or uprooted as 
the concrete member is being positioned.
    As a whole, paragraph (g)(1) is identical to the proposed 
provision, other than the location of the control line for precast 
concrete work and the clarification that any effective means to 
restrict entry to the zone is permitted. For example, if a home builder 
were operating under a fall protection plan, the home builder may 
designate the entire upper level of the home as a CAZ and restrict 
entry to that zone to only those workers needed to set roof trusses. 
The home builder could restrict entrance to the zone by placing a sign 
or by using tape or a chain to communicate to workers that access to 
the upper floor is restricted to only those employees identified in the 
fall protection plan. If the only way to reach the upper level is by 
stairway, the sign, tape or chain could be placed at the top or bottom 
of the stairway.
    The same situation could arise on a precast concrete site where the 
entire upper level is designated as the CAZ and all entrances to the 
level are marked to indicate that access is restricted. The intent of 
the provision is to restrict access to the danger zone. As long as the 
means chosen to restrict access is effective, i.e., workers do not 
enter the restricted area unless they are authorized by the fall 
protection plan to enter the CAZ, the intent is accomplished.
    The 6-foot limitation was proposed as an adequate distance away 
from the edge to warn employees that they are approaching an 
unprotected side or edge. The 25 foot maximum allows a reasonable 
amount of work to be done before the CAZ needs to be moved.
    Paragraph (g)(1) of the final rule also requires that the control 
line be connected on each side to a guardrail system or to a wall. OSHA 
proposed this language to ensure that there was no gap between the 
coverage of the controlled access zone (CAZ) and that of the fall 
protection required for other areas of the pertinent work zone. OSHA 
reminds employers that all employees working outside the controlled 
access zone (CAZ) must be provided fall protection as required by 
Sec. 1926.501(b)(1) if they may be exposed to fall hazards. As the CAZ 
changes [moves forward as the work progresses at the leading edge], it 
exposes unprotected sides and edges perpendicular to the leading edge. 
The employer must ensure that any employees who may be exposed to falls 
of 6 feet (1.8 m) or more at those perimeters are provided with fall 
protection that complies with Sec. 1926.501(b)(1). Again, OSHA notes 
that this situation only occurs when two groups of workers are working 
on the same level and one group of workers is working in a CAZ and the 
other is being protected by conventional fall protection systems.
    For example, precast concrete workers may be connecting floor or 
roof members at the leading edge while other workers are engaged in 
``grouting'' activities outside the CAZ. As each precast member is 
added, the CAZ moves forward and the control line moves forward, 
creating sections of unprotected sides and edges outside the CAZ from 
which workers engaged in grouting or other activities could fall. Those 
employees must be afforded protection from falls of 6 feet or more from 
the unprotected sides and edges of the floor, roof, or other walking/
working surface as required by Sec. 1926.501(b)(1); or as required 
under fall protection plans where such plans are permitted.
    Seedorf Masonry (Ex. 2-153) commented that the proposed provision 
caused confusion and asked if its system of using special stanchions 
which bolt onto floor edges to support guardrail systems would be 
eliminated by proposed paragraph (g)(1). OSHA observes that nothing in 
this final rule prohibits the use of the special stanchions described 
by Seedorf Masonry.
    The Precast/Prestressed Concrete Institute (PCI) (Exs. 2-44, 2-107, 
25-4, 27-7, and 27-10) recommended that the control zone lines for 
precast concrete erection be kept as much as 60 feet away from the 
leading edge and reinstalled from time to time as the leading edge 
changes location. They explained that ``* * * a member may be as long 
as 120 feet and, if it is necessary to rotate the member, at least half 
its length--60 feet--would be required to avoid entanglement in the 
control zone lines''. As noted above, OSHA agrees that additional 
distance may be necessary when performing precast concrete erection 
work for the reasons stated, and has revised paragraph (g)(1) 
accordingly.
    Paragraph (g)(2) requires control zones used during overhand 
bricklaying operations to be not less than l0 feet nor more than 15 
feet from the working edge where the overhand bricklaying operations 
are underway. These limits were developed after extensive consultation 
with industry and union representatives and review by the ACCSH. The 
enclosed zone is intended to provide overhand bricklayers with an area 
free of interference from other employees not performing related work. 
Paragraph (g)(2) prohibits employees, other than those performing 
overhand bricklaying and related operations, from being in CAZs that 
have been set up for the bricklaying operations.
    This provision is essentially the same as the proposed provision. 
One commenter (Ex. 2-21) suggested that the line designating the 
control zone be erected not less than 6 feet from the edge instead of 
the proposed 10 feet, while another commenter, Seedorf Masonry (Ex. 2-
153) stated its total agreement with the proposed 10-foot requirement. 
OSHA agrees that at least 10 feet of space is necessary to provide 
overhand bricklayers with adequate working space. Another commenter 
(Ex. 2-56), apparently confused by the requirement, noted that the 
provision needed clarification ``as it will relate to bricklayers 
working on the leading edge * * *.'' OSHA observes that overhand 
bricklaying operations are not considered leading edge operations. 
While the use of a controlled access zone is permitted for both 
operations, the criteria for the zone vary depending on whether the 
employee is laying bricks (or related work), constructing a leading 
edge, or performing some other activity in the controlled area.
    Paragraph (g)(3) requires the control lines to be made of ropes, 
wires, tapes, or other equivalent materials (i.e., material that can 
meet the requirements of paragraph (g)(3)), and supported on 
stanchions. Paragraph (g)(3)(i) requires the system to be flagged or 
otherwise clearly marked at 6-foot intervals. Paragraphs (g)(3)(ii) 
regulates the height of the control zone lines. Overhand bricklaying 
control zone height limits are higher than those for other work to 
allow the ready passage of materials underneath the line. Paragraph 
(g)(3)(iii) requires the line to have a minimum breaking strength of 
200 pounds. This minimum strength is required to assure that the lines 
will not break if an inattentive worker walks into the line.
    The proposed paragraph was identical, except as discussed below. 
There was only one comment on this provision. Seedorf Masonry (Ex. 2-
153) noted its total agreement with all of paragraph (g)(3).
    OSHA notes that it has revised proposed paragraph (g)(3) by 
removing the reference to ``access path.'' In the proposed rule, access 
path lines would have been used to identify paths from the controlled 
access zone to other areas on the floor or roof that bricklayers might 
need to gain access. OSHA has decided that these provisions could cause 
considerable confusion and, accordingly, has deleted the mention of 
access paths. Instead, OSHA has simply stated that a controlled access 
zone must be enlarged as necessary to permit overhand bricklaying and 
related work to take place.
    Paragraph (g)(4) sets forth criteria for setting up a controlled 
access zone on a floor or roof where guardrail systems are not in place 
prior to the beginning of overhand bricklaying operations. Paragraph 
(g)(5) sets forth criteria for setting up a controlled access zone on a 
floor or roof where guardrail systems are in place prior to the 
beginning of overhand bricklaying operations. These two paragraphs are 
essentially the same as proposed paragraphs (g)(4), (g)(5) and (g)(6).
    If a guardrail system has not already been set on the pertinent 
floor or roof where the bricklaying work is to be done, the controlled 
access zone must be large enough to enclose all points of access, 
materials handling areas and storage areas. Final rule paragraph 
(g)(5), which is essentially identical to proposed paragraph (g)(6) 
provides that where guardrail systems are already in place (because 
other trades are using them), and bricklaying work is to be done, those 
guardrail systems may be removed to the extent necessary to accomplish 
that day's work.
    One commenter stated that the proposed paragraphs (4) and (5) were 
quite confusing (Ex. 2-153). OSHA agrees that the language of the 
proposed paragraph (g)(4) was confusing because it included provisions 
for forming access paths which were two lines similar to control zone 
lines. As OSHA did in paragraph (g)(3) above, it has removed references 
to access path lines in paragraph (g)(4). The provision is now clear 
that if there are no guardrail in place already, the CAZ must be large 
enough to enclose all areas where the masons and mason tenders are 
exposed to fall hazards from unprotected edges. Seedorf (Ex. 2-104) 
also noted that the proposed provision appeared to prohibit employees 
from leaving the control zone unless there were guardrails on the open 
floor. OSHA observes that this perception is basically correct. The 
concept of a controlled access zone is to establish an area of limited 
size in which only certain employees can enter and work without fall 
protection because conventional fall protection systems cannot be used. 
Employees must be protected at all times from fall hazards at 
unprotected sides and edges when they leave the controlled access zone. 
For example, if a bricklayer is working on one side of the floor, a 
controlled access zone will be established for that area. When the 
bricklayer leaves the control zone and is exposed to fall hazards 
elsewhere on the floor or roof, fall protection is required.
    Proposed paragraph (g)(7) has been deleted because paragraph (g)(2) 
of the final rule already makes it clear that only those employees 
engaged in overhand bricklaying (including related work 
(Sec. 1926.501(b)(9)) are permitted in the controlled access zone. The 
only other employees that are permitted to work in CAZs are those 
employees so designated in a fall protection plan. In such cases, 
Sec. 1926.502(k)(9) requires the employer to identify those employees 
and does not permit other employees to enter the zone.
    Paragraph (h)--Safety monitoring systems. This paragraph contains 
the criteria which must be followed when safety monitoring systems are 
being used. Safety monitoring systems may be used to protect employees 
engaged in roofing operations on low-slope roofs (See 
Sec. 1926.501(b)(10)) and employees engaged in leading edge operations, 
precast concrete or residential construction work through the use of 
safety monitoring systems as part of a fall protection plan (See 
Sec. 1926.502(k)). Existing rule Sec. 1926.500(g) provides for the use 
of safety monitoring systems on low-slope roof perimeters during built-
up roofing work and the existing definition in existing 
Sec. 1926.502(p)(7) provides criteria for safety monitoring systems.
    Paragraph (h)(1) requires the employer to designate a competent 
person as the safety monitor and to ensure that the monitor meets 
certain requirements including being able to recognize fall hazards. 
The safety monitor is required to warn an employee who appears to be 
unaware of a fall hazard or is acting in an unsafe manner. The monitor 
must also be on the same surface and within visual sighting distance of 
the monitored employee and close enough to communicate orally with the 
monitored employee. The monitor may have additional supervisory or non-
supervisory responsibilities, provided that the monitor's other 
responsibilities do not interfere with the monitoring function. This 
provision effectively restates existing Sec. 1926.502(p)(7).
    Paragraph (h)(2) prohibits the use of mechanical equipment where 
safety monitoring systems are being used to protect employees from 
falling off low-slope roofs. This is essentially the same requirement 
as in existing Sec. 1926.500(g)(4).
    Paragraph (h)(3) prohibits employees not engaged in roofing work on 
low-sloped roofs or employees covered by a fall protection plan from 
being in an area where other employees are protected by a safety 
monitoring system. As explained in the preamble to the proposal, OSHA 
believes that the presence of extraneous employees in these areas can 
interfere with work procedures necessary for the effective use of the 
safety monitoring system. OSHA notes that this provision is consistent 
with the provisions of paragraph (k) which also prohibits employees 
from entering a CAZ because a safety monitoring system or other non-
conventional fall protection system is in use in the CAZ.
    Paragraph (h)(4), which has been added to the final rule, requires 
that each employee performing work in safety monitoring systems areas 
comply with directions from safety monitors to avoid fall hazards. Both 
the existing rule (Sec. 1926.502(p)(7)) and the proposed rule 
(Sec. 1926.502(h)(1)) clearly indicate that the safety monitor must be 
a ``competent person,'' which means that the monitor must be capable of 
identifying workplace hazards and have the authority to take prompt 
corrective measures. Within the context of the safety monitoring 
system, the ``corrective measures'' are to have the affected employees 
move away from the unprotected side or edge or use other work 
procedures to avoid fall hazards. OSHA has added this requirement to 
indicate clearly that employers must direct their affected employees to 
comply with the warnings of the safety monitor.
    There were several comments on the criteria for the use of safety 
monitoring systems. MOSH (Ex. 2-31) recommended that OSHA delete 
requirements relating to the safety monitoring systems which it felt 
would be difficult to enforce. In the final rule, OSHA allows the use 
of safety monitoring systems only where the employer can demonstrate 
that it is infeasible or creates a greater hazard to use other 
conventional systems, except on low-slope roofs, where employers may 
generally use a combination safety monitoring system and warning line 
system. OSHA believes that the use of safety monitoring systems are 
appropriate in situations where conventional fall protection systems 
cannot be implemented. It is, however, necessary for employers to 
recognize that merely designating an employee as the safety monitor 
will not meet the criteria of this paragraph. Persons who do not 
satisfy all of the criteria specified in this paragraph and whose other 
duties compromise their ability to monitor employees exposed to fall 
hazards do not meet the requirements for being safety monitors. Hence, 
the employer who uses such a person as a safety monitor will not be in 
compliance with the duty requirements of Secs. 1926.501 or 1926.502. In 
other words, having a designated safety monitor ``in name only'' is the 
same as not having a monitor at all. OSHA emphasizes that safety 
monitoring systems are a last resort when other conventional systems 
are infeasible--meaning that is it is impossible to accomplish the work 
using the conventional systems--or the conventional systems create a 
greater hazard. Hence, when employers encounter the infrequent 
situation which permits the use of safety monitoring systems as an 
alternative fall protection measure, employers must comply with each 
and every provision of this paragraph, because otherwise the safety 
monitoring system is invalid.
    NIOSH (Exs. 2-33 and 27-6), which expressed its opposition to the 
use of safety monitoring systems on leading edges (see discussion under 
Sec. 1926.501(b)(2) above), recommended that if such systems were 
permitted, OSHA should modify paragraph (h) to specify both the number 
of workers that can be monitored by one person, specify the area over 
which these workers may be distributed, and to set a maximum noise 
level to ensure effective communication. However, they offered no 
specific suggestions as to what those criteria should be. While OSHA is 
not specifying the number of employees that can be monitored by any one 
safety monitor, OSHA will expect such information to be included in 
fall protection plans when they are developed and the number of 
monitors will depend on the different functions the employees are 
performing while being monitored, the closeness of workers to monitors, 
and other such considerations. In other words, if one safety monitor is 
assigned to monitor employees who are not all in the same area, OSHA 
will deem the monitor unable to meet the requirements of (h)(1) and, 
therefore, conclude that there is no monitoring system in effect. OSHA 
expects there will be situations where one monitor is designated to 
monitor only 2 employees and other situations where a few more could be 
monitored. If a monitor is assigned to monitor 5 employees and 3 of 
those employees are working in front of the monitor, and the other 2 
are working behind the monitor, OSHA will determine that there is no 
monitor for the 2 employees who obviously cannot be under supervision 
if the monitor is monitoring the other three. Likewise, weather 
conditions can limit the use of safety monitors. OSHA will expect such 
information to be discussed in fall protection plans. For example, OSHA 
would not expect safety monitoring systems to be implemented in weather 
conditions that interfere with visibility.
    The Building Trades Employers' Association of Boston and Eastern 
Massachusetts, Inc. (Ex. 2-26) commented that, while it did ``not find 
fault with the concept [safety monitoring systems],'' it opposed the 
requirement in proposed paragraph (h)(1)(vi)--that monitors must not be 
so busy with other responsibilities that their monitoring function is 
encumbered--because that provision would, in effect, cause the hiring 
of additional personnel to act exclusively as monitors.
    OSHA observes that proposed paragraph (h) is intended to guide 
employers who must follow what OSHA itself considers to be the least 
acceptable option for protecting employees from falls.
    Another commenter, the Precast/Prestressed Concrete Institute (Ex. 
2-107) stated ``1926.502(h), Safety Monitoring Systems, is a practical 
and reasonable method to perform the work of the concrete hollow core 
industry * * *.''
    In addition, Seedorf Masonry (Ex. 2-153) stated its agreement with 
the requirements in paragraph (h)(1), but stressed that it would not 
want them to apply in control zones where overhand bricklaying 
operations are taking place. OSHA observes that safety monitoring 
systems are not listed as an option for fall protection in overhand 
bricklaying operations, so paragraph (h) would not be applicable. 
Again, OSHA points out that the use of safety monitoring systems is 
allowed only to protect employees engaged in roofing operations on low-
slope roofs or employees constructing leading edges, or engaged in 
precast concrete or residential construction work, who are operating 
under a fall protection plan meeting the requirements of 
Sec. 1926.502(k).
    Paragraph (i)--Covers. This paragraph sets the performance criteria 
for covers when they are used to protect employees from falling into or 
through holes in floors, roofs, and other walking/working surfaces. The 
proposed requirements, based on existing Sec. 1926.500(f)(5), were 
identical to the final rule, except as discussed below.
    Paragraph (i)(1) requires that covers in roadways and vehicular 
aisles be capable of supporting, without failure, at least twice the 
maximum axle load of the largest vehicle expected to cross over the 
cover. There were no comments on this provision.
    Paragraph (i)(2) requires that all other covers (those not 
addressed by paragraph (i)(1)) be capable of supporting, without 
failure, at least twice the weight of any employee (including any 
equipment or material the employee may be carrying) who may be on the 
cover. This provision differs from both the proposed and the existing 
rules. Existing Sec. 1926.500(f)(5)(ii) requires floor opening covers 
not located in roadways or vehicular aisles to be capable of supporting 
the maximum intended load. The proposed rule kept the maximum intended 
load requirement and added a requirement that a cover be able to 
support 250 pounds, based on what OSHA considered to be the average 
maximum weight of an employee with tools. One commenter (Ex. 2-46) was 
apparently concerned with OSHA's determination that 250 pounds 
represented the average employee with tools. The ACCSH recommended that 
no weight at all be placed on the covers addressed in proposed 
paragraph (i)(2) (Tr. 6/10/87; pp. 109-113). However, OSHA feels that 
it is reasonable to anticipate that employees will walk on covers. OSHA 
is also concerned that employees could fall onto the covers, going 
through them if they were not sufficiently strong and secured. As one 
ACCSH member put it, (Tr. p. 110) ``Sometimes a material used for 
covers is not sufficient to handle weights on them.''
    Based on the comments and recommendations received, OSHA has 
determined that it is inappropriate to prohibit employees from being on 
covers and that employees will be adequately protected by a requirement 
for each cover to be strong enough to prevent them from falling into 
holes. Therefore, OSHA is revising proposed paragraph (i)(2) to require 
covers to support twice the weight of the employees, equipment and 
materials that may be put on the cover. As noted above, paragraph 
(i)(1) has set ``twice the weight'' as the strength requirement for 
covers over which vehicles will pass. OSHA believes twice the weight of 
the employee, equipment and materials would be appropriate here also.
    Paragraph (i)(3) requires covers to be secured when installed so as 
to prevent accidental displacement by wind, equipment, and employees. 
Proposed paragraph (i)(3), which was based on existing 
Sec. 1926.500(f)(5)(ii), required covers to be installed so as to 
prevent accidental displacement. OSHA has revised the proposed 
paragraph to state more clearly OSHA's intent that covers be secured 
when installed so that employees cannot easily remove them, and so that 
wind and equipment will not accidentally cause covers to be displaced.
    Paragraph (i)(4) requires all covers to be color coded or the word 
``HOLE'' or ``COVER'' must appear on the cover to serve as a warning to 
employees of the hazard. A note in paragraph (4) indicates that OSHA 
does not intend for employers to color code or mark the permanent cast 
iron manhole covers or steel grates which cover street or roadways 
openings or similar kinds of covers that may be encountered on a 
construction worksite.
    Paragraph (i)(4) is a new requirement in the final rule. The change 
in paragraph (i)(3) and the new provision in (i)(4) have been made 
after consideration of recommendations presented to OSHA by ACCSH (Tr. 
6/10/87; pp. 109-113) and as a result of the evaluation of the comments 
received in response to Issue #7 of the proposed rule, in which OSHA 
specifically asked whether or not covers should be marked or color 
coded.
    Many commenters, in response to Issue #7, supported adding a 
requirement that employers mark or color code covers to prevent 
accidental displacement (Exs. 2-12, 2-20, 2-36, 2-41, 2-43, 2-45, 2-46, 
2-50, 2-89, and 2-99). For example, the BCMALU (Ex. 2-46) commented 
that covers should be marked and color-coded so the worker does not 
pick up a cover and walk into the hole. They explained that the marking 
on the cover would alert the worker that it is something other than a 
plain piece of lumber. Other commenters supported both marking and 
color coding. One commenter (Ex. 2-99) approved of marking covers, but 
stressed the importance of covers being sufficiently strong and 
secured. Another commenter (Ex. 2-153) supported the provisions in 
paragraph (i) as they were proposed.
    Bristol Steel and the NEA (Exs. 2-12 and 2-43) commented, ``Lifting 
covers unintentionally and then stepping through the uncovered hole is 
a significant hazard which could be reduced if covers were marked or 
fastened down.'' They listed three accidents caused by unintentional 
removal of covers. The accidents resulted in one fatality and two 
permanent disabilities. They also pointed out ``it is not always 
feasible to fasten covers to permanent building materials without 
causing unacceptable damage; consequently the alternative for marking 
covers is proposed.'' Bristol Steel and NEA suggested that 
Sec. 1926.502(i)(3) be changed to read ``All covers shall be installed 
so as to prevent accidental displacement. Covers shall be marked to 
indicate their function as a cover or shall be securely fastened down 
to prevent unintentional removal.''
    The United Union of Roofers, Waterproofers and Allied Workers (Ex. 
2-99) commented that covers should be strong enough to withstand the 
weight of men and materials, and that they should be securely fastened 
to prevent their being displaced. In addition, while stating that they 
had no objection to marking covers to indicate their function, they 
stated that marking covers ``must not be allowed in lieu of securely 
fastening such a cover to prevent accidental displacement.''
    The ACCSH recommended that covers be painted a distinctive color 
and be fastened in place and that no weight should be permitted on 
them. (Tr. 6/10/87; pp. 109-113).
    A few commenters responded that covers should neither be marked nor 
painted because of maintenance problems, i.e., the markings would wear 
off. (Exs. 2-16, 2-19, 2-47, 2-92 and 2-140). As discussed above, OSHA 
agrees that painting or labeling covers is necessary for the enhanced 
safety afforded affected employees.
    Paragraph (j)--Protection from falling objects. This paragraph sets 
forth the performance criteria for providing protection from falling 
objects. All of the provisions are identical to the proposed 
provisions, except as provided below.
    Paragraph (j)(1) requires toeboards, when used, to be erected along 
the edge of overhead walking/working surfaces for a distance sufficient 
to protect employees working below. This is a change from existing 
rules in Secs. 1926.500(b)(1), (2), (3)(ii), and (8), which require 
toeboards around floor, roof, and platform holes and openings 
regardless of whether or not employees are working below. However, 
paragraph (j)(1) is consistent with the intent of the existing rule in 
Sec. 1926.500(d)(1) and Sec. 1926.501(e) of the final rule which 
require protection only where employees below are exposed to the hazard 
of falling objects.
    Paragraph (j)(2) is a new requirement and it specifies toeboards 
shall be capable of withstanding, without failure, a force of at least 
50 pounds. This requirement was proposed to set a minimum strength for 
toeboards to ensure the ability of the toeboard to restrain falling 
objects.
    Paragraph (j)(3) specifies how toeboards are to be installed and is 
essentially the same as the existing requirement in 
Sec. 1926.500(f)(3)(i), except the minimum height of the toeboard has 
been reduced from 4 inches to 3\1/2\ inches. In the NPRM, OSHA proposed 
to change not only the maximum vertical height of the toeboard, but the 
size of the opening or gap between the toeboard and the walking/working 
surface. The existing rule set the maximum size of that opening at \1/
4\-inch and OSHA proposed to allow a \1/2\-inch clearance. OSHA 
received one comment on the proposed provision. The TVA (Ex. 2-20) 
noted that ``many small tools can pass through a one-half inch opening 
* * *.'' OSHA also notes that the ANSI A1264.1-1989 standard sets \1/4\ 
inch as the maximum clearance. Based on this information, OSHA has 
determined that the existing rule more adequately addresses the hazard 
and has revised the proposed provision accordingly.
    Paragraph (j)(4) provides that additional protection, such as 
paneling or screening erected from the working level or toeboard to the 
top of the top rail or midrail, must be used where tools, equipment, or 
materials are higher than the top of a toeboard. This requirement is 
substantively the same as the existing requirement in 
Sec. 1926.500(f)(3)(ii).
    Seedorf Masonry (Ex. 2-153) questioned whether employers would have 
to install a screening system on floors or scaffolds since they 
typically pile brick and block units on floors and scaffolds and the 
pile is higher than the height of a toeboard. OSHA notes that the use 
of toeboards, screens or guardrail systems is one of the options 
allowed in Sec. 1926.501(c) of the final rule. Paragraph (j)(4) simply 
requires that employers who choose to use toeboards as the method of 
preventing objects from falling onto employees working below, take the 
necessary precautions to ensure that objects do not fall over the 
toeboard. Employers can choose from among other options listed in 
Sec. 1926.501(c) to provide the necessary protection. However, if an 
employer chooses to use toeboards, the employer would be required to 
install panels or screens that are high enough to keep bricks from 
falling to lower levels if the height of the bricks exceeds the height 
of the toeboard, so that appropriate protection is afforded employees 
working below.
    Paragraph (j)(5) requires that when guardrails are used to prevent 
objects from falling, the openings in the guardrail must be small 
enough to retain the potential falling objects. This is essentially the 
same as the existing requirement in Secs. 1926.500(c)(1)(ii) and 
(f)(7)(ii) except the specific limitations on hole size have been 
deleted.
    Paragraph (j)(6) contains housekeeping provisions for overhand 
bricklaying operations which are intended to prevent tripping and to 
prevent displacement of materials and equipment to areas below the 
walking/working surface.
    Paragraph (j)(7) sets forth provisions for storing materials and 
equipment during roofing operations. These are essentially the same 
requirements as those set in existing 1926.500(g)(5) (vi) and (vii).
    Paragraph (j)(8), which did not appear in the proposal, requires 
that when canopy structures are erected, they shall be strong enough to 
prevent collapse or penetration of falling objects.
    In Issue #8, OSHA noted that proposed Sec. 1926.501(e) [final rule 
Sec. 1926.501(c)] allowed the use of protective canopies for falling 
object protection and requested comments on what criteria should be 
specified in Sec. 1926.502(j) to ensure proper protection. SSFI (Ex. 2-
89) commented that ``Historically canopies have been designed for 150 
to 300 pound design loads or `light debris'. It is recommended that use 
of this type of canopy be continued.'' The National Constructors 
Association (Ex. 2-45) commented that a performance standard would be 
more appropriate, stating ``It is not practical to attempt to write 
regulations on protective canopies * * * .'' ACCSH (Tr. 6/10/87; p. 
113) recommended that canopy structures be strong enough to avoid 
collapse or penetration when falling objects strike them. Bristol Steel 
and the NEA (Exs. 2-12 and 2-43) stated, ``No additional criteria for 
protective canopies are needed.'' Miller and Long (Ex. 2-41) commented 
that many methods of protection against falling objects are available 
and that, given the changeability of the work environment, ``a variety 
of methods should be included. Another commenter, Ex. 2-46, stated 
``Canopies or catch alls should be used when chipping of concrete with 
electric or pneumatic chipping guns are used.''
    In view of the comments received, OSHA has determined that the 
record does not contain sufficient information to formulate detailed 
criteria for the many types of canopy structures. However, the record 
does support OSHA action to set a minimum level of performance for 
canopies suited to their function which is to prevent falling objects 
from reaching employees. OSHA agrees that the canopy must be strong 
enough to perform its intended function if the employer provides canopy 
structures as the method to protect employees from falling objects.
    Paragraph (k)--Fall protection plan. OSHA is promulgating paragraph 
(k), which was not part of the proposed rule, to address the measures 
that employers who are constructing leading edges, or are engaged in 
precast concrete construction or residential construction work must 
take when they establish, pursuant to final rule Secs. 1926.501(b)(2), 
(b)(12) or (b)(13), that it is either infeasible or would create a 
greater hazard to protect employees from fall hazards using guardrail 
systems, safety net systems, or personal fall arrest systems for 
employee fall protection. OSHA has explained under 
Secs. 1926.501(b)(2), (b)(12) and (b)(13) what conditions could enable 
a contractor to meet the criteria to use a fall protection plan.
    Final rule Secs. 1926.501(b)(2),(b)(12) and (b)(13) contain notes 
which indicate clearly that OSHA approaches the pertinent work 
activities with the presumption that it is feasible and will not create 
a greater hazard to implement at least one of the three specified 
conventional fall protection systems. The notes also underscore that 
the employer has the burden of establishing that it is appropriate to 
implement a fall protection plan which complies with Sec. 1926.502(k) 
for a particular workplace situation. OSHA believes that the inclusion 
of these notes will facilitate understanding of and compliance with 
paragraph (k) of the final rule.
    Paragraph (k) had its origin in comments received in response to 
Issue #2 of the notice of hearing in which OSHA asked if there were 
areas or operations, in addition to those already identified in 
proposed Sec. 1926.501, which had unique fall protection requirements 
not addressed by the proposed standards and in a Notice of Record 
Reopening in (57 FR 34659; August 5, 1992) discussed above in relation 
to Sec. 1926.501(b)(12). OSHA requested commenters to describe such 
areas and operations in detail and to discuss the fall protection 
measures which would be appropriate for those situations.
    In response, the Precast/Prestressed Concrete Institute (PCI), in 
addition to their written comments (Ex. 2-44, 2-106, and 2-107), 
presented testimony at the public hearing noting that, ``* * * our 
field erection is work not appropriately covered by the proposed 
regulations; rather, precast concrete erection should be listed as a 
separate subpart (or preferably included along with steel erection in 
Subpart R).'' A full discussion of PCI's comments, along with OSHA's 
decisions, are provided along with the discussion of 
Sec. 1926.501(b)(12) above.
    A number of commenters (Exs. 27-5, 27-7, 27-10, 27-21, 27-22, and 
27-28) responded to the reopening of the record and suggested that OSHA 
promulgate the criteria from the Notice of Record Reopening as the 
alternative ``fall protection plan'' for the precast concrete 
construction industry.
    Several commenters (Exs. 27-1, 27-2, 27-6, 27-9, 27-25, 27-36, and 
27-42) opposed allowing precast concrete construction employers to 
protect their employees by any means other than conventional fall 
protection (guardrail systems, personal fall arrest systems and safety 
net systems). Some of these commenters (Exs. 27-6, 27-9 and 27-25) were 
especially skeptical of safety monitoring systems as an alternative to 
conventional measures. In particular, one commenter (Ex. 27-25) stated:

    There are no conditions where OSHA should allow precast concrete 
construction employers to institute anything other than a 
conventional fall protection system to protect workers.
    Safety monitoring, controlled access zones systems and a fall 
protection plan are examples of additional controls which should be 
considered in addition to conventional fall protection systems.
    Regulations must be developed which will require design and 
installation of anchor points during the construction process so 
that workers will have attachments available for fall arrest 
protection. Exposure time should not be a considering factor when 
evaluating whether to protect a worker. The protection of any worker 
who needs to come within two feet of a floor or roof edge for a few 
seconds should not rely on an observer when it could be accomplished 
by an area limiting tethering device, or other fall arrest system. 
the use of a ``safety monitor'' should not be allowed in place of 
personal fall protection equipment.

    This commenter invoked a comment by NIOSH (Ex. 27-6) which stated 
as follows:

    Reliance on passive measures, such as safety harnesses, is 
generally recognized as more effective than reliance on active 
measures that require worker involvement and attention in order to 
function. Using a monitor to keep another worker from the edge would 
require the active involvement of both the monitor and the worker to 
ensure safety.

    As discussed above in relation to Sec. 1926.501(b)(2) of the final 
rule, OSHA believes that construction employers, including those who 
erect precast concrete structures, can, in general, protect their 
employees from fall hazards with conventional fall protection, and is 
requiring that they do so as a general rule. The Agency agrees with the 
commenters who have stated that including fall protection in the 
planning and designing of construction work (such as by including 
anchor points for personal fall arrest systems in the construction 
design specifications) can enable construction employers to implement 
appropriate protection. OSHA acknowledges, however, that there may be 
circumstances where, despite their best efforts, construction employers 
cannot provide conventional fall protection, such as when grouting 
operations are underway, and when home builders are setting or bracing 
roof trusses. When an employer establishes, through compliance with 
Sec. 1926.501(b)(12), that such circumstances exist, the Agency 
believes that it is appropriate to require the implementation of 
alternative measures through which the employer minimizes the fall 
hazards for affected employees.
    OSHA has already recognized that circumstances may arise in the 
course of overhand bricklaying and roofing operations which would 
preclude the use of conventional fall protection. In such cases the 
Agency requires that employers take specific alternative measures to 
minimize fall hazards for affected employees. The Agency believes that 
requiring those alternative measures, when conventional fall protection 
cannot be used, will provide the best opportunity to avert employee 
injury and death. OSHA has determined that it is also appropriate to 
set alternative measures for leading edge construction, precast 
concrete construction, and residential construction work so employers 
have clear direction as to what they must do if the use of conventional 
fall protection is infeasible or would cause a greater hazard in a 
particular work area.
    As discussed above, the Agency has set criteria in 
Sec. 1926.501(b)(2), (b)(12), and (b)(13) for employers who seek to 
establish that the use of fall protection is infeasible or would create 
a greater hazard for employees when constructing leading edges or 
performing precast concrete or residential construction work. Employers 
who satisfy those criteria must implement a written ``fall protection 
plan'' which complies with Sec. 1926.502(k). OSHA is adding Non-
mandatory Appendix E to provide a sample fall protection plans which 
contains the elements and the detail necessary for the Agency to 
consider the plan to be in compliance with paragraph (k). This non-
mandatory appendix is provided for the benefit of employers who need 
guidance in developing their fall protection plans.
    Paragraph (k)(1) provides that a written fall protection plan must 
be prepared by a ``qualified'' person (as defined by 29 CFR 1926.32(m), 
that the plan be developed specifically for the site where the work is 
being done, and that the plan be maintained up to date. The definition 
in Sec. 1926.32(m) describes ``qualified'' as a person who ``has 
successfully demonstrated his ability to solve or resolve problems 
relating to the subject matter, the work, or the project.'' The 
inclusion of these requirements was suggested by PCI (Ex. 25-4) and 
addressed in the August 5, 1992, record reopening notice (57 FR 34656).
    Employers whose workplace situations satisfy the criteria of 29 CFR 
1926.501(b)(2), (b)(12) or (b)(13) still must develop and implement 
alternative measures that protect affected employees from fall hazards. 
It is clear that the abilities of the personnel who develop those 
measures will strongly influence their effectiveness. The Agency has 
determined that the abilities of a qualified person are needed to 
ensure that the fall protection plan minimizes fall hazards. OSHA notes 
that an employer may use the services of more than one qualified person 
to comply with these requirements, as long as (1) those persons, 
collectively, are qualified to prepare the fall protection plan and 
approve any changes; and (2) the resulting plan complies with the 
applicable requirements of the standards.
    Paragraph (k)(1) also provides that the fall protection plan must 
be developed for the specific site where the work is being done. OSHA 
notes that the designs, erection plans and circumstances for one site 
will, in many cases, differ significantly from those for another site. 
Accordingly, the fall protection plan for the one site may well be 
inapplicable to the other or may require substantial modification 
before it can be used. This provision was suggested by PCI (Ex. 25-4) 
and was addressed in the August 5, 1992, notice of record reopening (57 
FR 34659). The Agency anticipates that compliance with this requirement 
will enable an employer to take measures which minimize the fall 
hazards at each site.
    Paragraph (k)(1) also requires that the fall protection plan be 
maintained up to date. The employer must review the fall protection 
plan as necessary to determine if it still fits the workplace situation 
and must modify the plan as necessary to maintain its effectiveness, 
such as when elements of the plan have become inapplicable due to 
changes in the design, erection plan or other circumstances of a site. 
This provision was suggested by PCI (Ex. 25-4) and was addressed in the 
August 5, 1992, notice of reopening (57 FR 34659). It provides clear 
notice to employers that they have an ongoing responsibility to monitor 
their projects and to revise their fall protection plans to address 
changed conditions.
    Paragraph (k)(2) provides that any changes in a fall protection 
plan must be approved by a qualified person. The qualified person may 
either sign or initial and date the changed portion of the fall 
protection plan to indicate approval of the plan as modified. This 
provision, like paragraph (k)(1), reflects the Agency's belief that the 
characteristics set out in 29 CFR 1926.32(m) are needed to assure that 
the person who sets the terms of the fall protection plan has the 
requisite ability and judgment. This provision was suggested by PCI 
(Ex. 25-4) and was addressed in the August 5, 1992, notice of record 
reopening (57 FR 34659). The decision regarding the acceptability of 
any potential plan changes may be made by any person or persons 
``qualified'' to do so. OSHA believes that compliance with this 
paragraph will ensure that changes to fall protection plans receive the 
same careful scrutiny as the original plans.
    Paragraph (k)(3) requires that a copy of the fall protection plan, 
with all approved changes, be maintained at the job site, available for 
inspection by employees and their authorized representatives. In many 
cases, the opportunity to review the plan will provide the necessary 
reassurance to employees that the employer has taken appropriate 
measures to minimize exposure to fall hazards. In other cases, review 
of the plan will alert employees to deficiencies that need to be 
brought to the employer's attention for correction. This provision was 
suggested by PCI (Ex. 25-4) and was addressed in the August 5, 1992, 
notice of record reopening (57 FR 34659). The Agency believes that 
compliance with this paragraph will both facilitate operations and help 
ensure that the fall protection plan fits the actual workplace 
conditions.
    Paragraph (k)(4) provides that the implementation of the fall 
protection plan must be supervised by a ``competent person''. That term 
is defined in 29 CFR 1926.32(f) to mean ``one who is capable of 
identifying existing and predictable hazards in the surroundings or 
working conditions which are unsanitary, hazardous, or dangerous to 
employees, and who has authorization to take prompt corrective measures 
to eliminate them.'' The proper implementation of a fall protection 
plan will require unflagging vigilance and decisive action. Without the 
``built-in'' protection of a guardrail, safety net or personal fall 
arrest system, employees must rely on safety monitors and other 
measures to warn them away from fall hazards. This provision indicates 
clearly that employers must assign supervisors who can promptly 
identify and correct any problems arising under the plan. This 
provision was suggested by PCI (Ex. 25-4) and was addressed in the 
August 5, 1992, notice of record reopening (57 FR 34659).
    OSHA notes that a ``competent person'' who also has the abilities 
of a ``qualified person'' will be particularly well-positioned to 
develop and implement solutions to fall protection problems. The Agency 
has not required that the supervisor be both ``competent'' and 
``qualified'', because OSHA believes that such consolidation of 
function is not essential for employee protection. Also, the Agency 
recognizes that more than one person can be a ``competent person'' for 
the purposes of paragraph (k)(6), as long as those persons, 
collectively, exercise the requisite oversight and authority.
    Paragraph (k)(5) provides that an employer who determines that 
conventional fall protection cannot be used at a particular worksite 
must document the reason why the use of conventional fall protection 
systems (guardrail systems, safety net systems, or personal fall arrest 
systems) are infeasible or why their use creates a greater hazard. OSHA 
has provided guidance in its discussion of Sec. 1926.501(b)(2), (b)(12) 
and (b)(13) to assist employers in identifying what constitutes 
infeasibility and greater hazard. Employers must explain in writing, 
before work begins, for each of the three conventional systems, why 
those systems cannot be used at the specific location where the fall 
hazard is present. This provision was suggested by PCI (Ex. 25-4) and 
was addressed in the August 5, 1992, notice of reopening (57 FR 34659).
    The process of developing the rationale will help the employer to 
understand the real limits, if any, on the use of fall protection. An 
employer who at first assumes that conventional fall protection cannot 
be used may well discover upon closer examination that employees in all 
or part of those operations can use conventional fall protection. In 
addition, the documentation required by paragraph (k)(5) will enable 
OSHA to determine if there is an objective basis for the employer's 
finding that its operations meet the criteria of Sec. 1926.501(b)(2), 
(b)(12), or (b)(13). The purpose of paragraph (k)(5) is to limit the 
use of fall protection plans to those situations where such use is 
justified.
    Paragraph (k)(6) requires the employer, after complying with 
paragraph (k)(5) above, to document in the written fall protection plan 
the measures that the employer will take to reduce or eliminate the 
fall hazard in work areas where conventional fall protection systems 
cannot be used. For example, if safety monitoring systems and control 
zone systems are going to be used, the written plan must so state. The 
employer must comply with all of the provisions described in the fall 
protection plan as alternative measures. It will not be acceptable for 
employers, under paragraph (k)(6) to list ``nothing'' or ``no measures 
to be taken'' as the alternative measure. At the very minimum, the 
safety monitoring system (see paragraph (k)(8) must be employed and all 
of the criteria in paragraph (h) of this section followed. OSHA notes, 
at this point, that if a safety monitoring system is to be used, the 
designated monitor must fulfill all of the criteria in paragraph (h). 
If monitors are given other work assignments, such as those discussed 
under paragraph (h) of this section, which render them unable to 
monitor other employees effectively, OSHA will view that situation as 
``not in compliance.'' Therefore, employers may need to designate more 
than one monitor so that a monitor is always available to fulfill the 
criteria of Sec. 1926.502(h).
    In situations where conventional systems are not used, OSHA does 
not encourage employers to elect the safety monitoring system as a 
first choice. Rather, the Agency will permit it to be used in those 
circumstances when no other alternative, more protective measures can 
be implemented. Examples of such more protective measures include 
having employees work from scaffolds, ladders, or vehicle mounted work 
platforms to provide a safer working surface and thereby reduce the 
hazard of falling. The written plan must include a discussion of these 
other measures and the extent to which they can be used. The employer 
should also note where the use of those measures would not reduce 
exposure, would be unreasonable, infeasible or would create a greater 
hazard. The employer's failure to perform this evaluation as part of 
the plan will support an OSHA determination that the employer does not 
have a fall protection plan and OSHA will consider the employer to be 
in violation of Sec. 1926.501(b)(2), (b)(12), or (b)(13). OSHA will 
also expect safe work practices to be elements of the alternative 
measures. For example, employees engaged in grouting operations would 
be expected to position themselves so their backs are not to the fall 
hazard. Employees on ladders would use a leg lock to position 
themselves more securely than they would otherwise be. In brief, 
employers need to preplan the work and plan the use of safe work 
practices that eliminate or reduce the possibility of a fall.
    The choice of alternative fall protection systems will be 
particularly important when, pursuant to 29 CFR 1926.501(b)(2), 
(b)(12), or (b)(13), an employer establishes that it must use 
alternatives to conventional fall protection. Accordingly, OSHA has 
determined that the employer must do what it can to minimize exposure 
to fall hazards, before turning to the use of safety monitoring systems 
(29 CFR 1926.502(h) under a fall protection plan. The inclusion of this 
requirement is based on submission from the PCI (Ex. 25-4) and was 
addressed in the August 5, 1992, record reopening notice (57 FR 34657).
    Paragraph (k)(7) requires the employer to identify in the plan, 
each location where conventional fall protection cannot be used and to 
classify those locations as controlled access zones. Controlled access 
zones must conform to the criteria in paragraph (g). Compliance with 
this provision will provide a reference point to enable the employer to 
distinguish between those work areas where the fall protection plan 
applies and those where it does not. This provision was suggested by 
PCI (Ex. 25-4) and was addressed in the August 5, 1992, notice of 
record reopening (57 FR 34657). It was also recommended by Ryland, the 
Home Builders Association of Maryland, and Hallmark Builders (Ex. 27-
23, 27-24, 27-26).
    OSHA has determined that, when it is impossible to perform the work 
with conventional fall protection, the work must be performed in a 
controlled access zone (CAZ). The CAZ prevents employees who are not 
engaged in the activities covered by the fall protection plan from 
being exposed to fall hazards in the areas where those activities are 
being conducted.
    Paragraph (k)(8) requires that a safety monitoring system must be 
implemented where no other alternative measures have been implemented. 
Safety monitoring systems must comply with the criteria in 
Sec. 1926.502(h). There has been considerable discussion above in 
relation to Secs. 1926.501(b)(2) and 1926.502(h) regarding the role of 
safety monitoring systems in minimizing exposure to fall hazards. OSHA 
has added this requirement because it believes that employers must, at 
a minimum, have a competent person assigned to monitor those employees 
who have not been provided conventional fall protection to warn the 
employees when they are acting in an unsafe manner or approaching an 
unprotected side or edge, among other activities when other, more 
protective measures, are not used.
    PCI (Ex. 27-7) as discussed above, supported the use of safety 
monitoring systems and also commented that some contractors use safety 
monitoring systems now as part of their fall protection efforts, 
stating that ``* * * safety monitoring or controlled access zones 
systems in conjunction with a fall protection plan is more safe * * 
*.'' Rocky Mountain Prestress (Ex. 27-8) also supported the use of 
safety monitors as part of a fall protection plan.
    Paragraph (k)(9) provides that the fall protection plan must 
identify, by name or other method, those employees who are authorized 
to work in CAZs. The paragraph further requires that only employees 
identified in the fall protection plan be allowed to enter CAZs. This 
provision was suggested by PCI (Ex. 25-4) and was addressed in the 
August 5, 1992, notice of record reopening (57 FR 34657).
    OSHA anticipates that compliance with this paragraph will enable an 
employer to maintain control over access to a CAZ, minimizing the 
number of employees exposed to fall hazards. This provision, like the 
rest of paragraph (k), reflects the Agency's position that although 
there may be situations where fall protection cannot be used, any 
deviation from the general requirements for fall protection must be 
construed as narrowly as possible.
    Paragraph (k)(10) provides that, if an employee falls while 
performing work covered by a fall protection plan or there is other 
reason to believe that the substance or implementation of the plan is 
deficient (e.g., a near miss), the employer must review the fall 
protection plan and make any changes in work practices, training, 
erection procedures, or construction practices needed to correct any 
deficiencies in the plan. Given the immediacy of the hazards to which 
employees covered by a fall protection plan may be exposed, it is 
essential that contractors promptly revise their plans to incorporate 
what they learn through experience.
    This paragraph underscores the Agency's determination that 
employers must minimize any fall hazards to which employees might be 
exposed through the use of fall protection plans. This provision was 
suggested by PCI (Ex. 27-22), and was endorsed by Rocky Mountain 
Prestress, Inc. (Ex. 27-28) for the precast/prestress concrete 
industry. Rocky Mountain further stated that they had implemented a 
fall protection plan and it ``has been very successful on several major 
precast projects * * *.''
    Both PCI and Rocky Mountain submitted sample fall protection plans 
(Exs. 27-22 and 27-28) which have been used by OSHA in the development 
of non-mandatory appendix E-- Sample Fall Protection Plans.
    One final comment that is not related to any of the above 
discussion was heard at the public hearing on the proposed rule, when 
WACO International (Tr. 03/22/88, p. 45) presented testimony regarding 
a hydraulic, self-climbing safety screen. They suggested that it was an 
alternative to safety net systems and other conventional devices used 
for protecting workers from exterior fall hazards. WACO requested that 
OSHA revise existing Sec. 1926.105(a) to specifically identify safety 
screens as a viable option for compliance with perimeter protection 
safety standards. They also stated that safety screens, unlike safety 
nets, do not require added hours of perimeter exposure after the 
installation to maintain them.
    OSHA observes that information on the use of such safety screens is 
limited since the screens have been used in Australia, not in the 
United States. The WACO representative did testify, however, that no 
one had fallen off the side of a building in the 10 years that the 
screen had been used in Australia (Tr. 3/22/88. pg. 47).
    Based on the limited information and evidence available to OSHA at 
this time, OSHA has decided not to incorporate specific provisions for 
safety screens in the final rule at this time. However, OSHA notes that 
such screens may be acceptable as a safety net system or guardrail 
system provided the screen can meet the performance criteria set forth 
in the various paragraphs in Sec. 1926.502 for such systems. Therefore, 
nothing in subpart M shall be construed to prohibit the use of safety 
screens.
Sec. 1926.503--Training
    The introductory text states that this section supplements and 
clarifies the requirements of Sec. 1926.21 regarding the hazards 
addressed in subpart M.
    The paragraph (a) requires employers to provide a training program 
for each employee exposed to fall hazards so that each employee can 
recognize fall hazards and know how to avoid them. This section 
identifies components of the requisite training, but does not specify 
the details of the training program.
    Employers need not retrain employees who were trained by a previous 
employer or were trained prior to the effective data of the standard, 
as long as the employee demonstrates an understanding of the subjects 
covered by paragraph (a) of this section.
    Paragraph (a) also states the subject areas to be addressed in the 
required training programs. The list of subjects reflects OSHA's 
determination that fall protection equipment and systems are only 
effective when they are properly designed, built, located, maintained, 
and used. Employers are required to ensure that each employee is 
trained, as necessary, by a competent person qualified in the following 
areas: The nature of the fall hazards in the work area; the correct 
procedures for erecting, maintaining, disassembling, using and 
inspecting the fall protection systems to be used; the role of 
employees in the safety monitoring systems when used; the role of 
employees in fall protection plans; and the standards contained in 
subpart M.
    Employees covered by a fall protection plan will, for example, need 
training to understand and to work effectively within the constraints 
of a CAZ. Affected employees will also need training on how to work 
with a safety monitor if a monitor is in use, to ensure that they 
respond appropriately when they hear a warning. OSHA recognizes that 
much of the information covered by training will be site-specific, so 
the Agency is framing this provision in performance-oriented terms.
    This approach to training provides flexibility for the employer in 
designing the training program. The proposed paragraph has been amended 
to require that the training be provided by a ``competent person.'' 
This provision was added at the recommendation of the ACCSH (Tr. 6/9/
87; P. 266). OSHA agrees that the involvement of a competent person who 
is qualified in the subject areas provides appropriate assurance that 
employees will be adequately trained. OSHA has also deleted the words 
``and instructed'' from the introductory text of proposed paragraph 
(a)(1) for the sake of clarity.
    In Issue #5, OSHA requested public comment on whether or not a more 
specific requirement for training would be appropriate. OSHA also asked 
for data on the costs and effectiveness of training requirements in 
reducing the risk of injuries or fatalities, and whether more or less 
specific requirements were appropriate. In addition, commenters were 
asked to respond with information about currently available safety 
programs and their adequacy; the safety records of employees who have 
been trained; the scope and necessary elements of training programs; 
the relationship of the additional specific provisions in 
Sec. 1926.503(a)(2) with the more general Sec. 1926.21 requirements; 
costs and benefits related to this issue; and any recordkeeping burdens 
these provisions might impose.
    Many commenters responded to this issue by commenting on the need 
and value of employee training. (Exs. 2-6, 2-9, 2-12, 2-19, 2-23, 2-43, 
2-46, and 2-50). Most of these commenters also stated their belief that 
the proposed requirements for training and retraining were adequate, 
with some commenters noting that further requirements were unnecessary 
(Exs. 2-12, 2-19, 2-23, 2-43). Bristol Steel and the NEA (Exs. 2-12 and 
2-43) commented as follows: ``Suitable training is an essential element 
of accident prevention. The specific training requirements proposed in 
Section 1926.503 are appropriate and necessary to inform employees of 
accident prevention measures* * *.''
    The AGC (Exs. 2-16, 2-47, and 2-92) indicated that specific 
training requirements did not provide the flexibility needed to cover 
all construction situations, observing that foremen and supervisors 
provided the more specific type of training. Also, a commenter (Ex. 2-
51) noted the mobility of the workforce and other factors and 
recommended that OSHA refrain from being specific in the training 
requirements. The commenter also stated that the general requirements 
for training in Sec. 1926.21 are more pertinent to construction. The 
MCISC (Ex. 2-140) stated, ``We believe that training is the key to 
accident reduction but also that it is already covered in the existing 
OSHA standard under 1926.20 and 1926.21.''
    On the other hand, R&TC (Ex. 2-36) commented that more specific 
requirements were needed for live demonstrations (under controlled 
conditions). The National Constructors Association (Ex. 2-45) also 
commented that ``Requirements for training should address specifics as 
to task and hazard involved.'' The ANSI Z359 Committee (Ex. 2-50) 
suggested that ``Fall protection training should perhaps be the subject 
of a national standard.'' ACCSH recommended that the training be given 
by a competent person. (Tr. 6/10/87; p. 95).
    Also, the Roofers Union (Ex. 2-99) in support of more specific 
requirements, commented that ``These requirements must be specific to 
avoid employers merely handing out material for workers to read.'' The 
commenter also stated that competent persons must conduct the training.
    Finally, other commenters (Exs. 2-89 and 2-95) offered to develop 
training programs in support of the OSHA training requirements. The 
SSFI (Ex. 2-89) commented that its members ``are willing to assist OSHA 
in developing training programs that would be used for these purposes 
by the employer prior to the employee starting work at a job site.'' 
They also commented that on-the-job training should not be a substitute 
for prior training. The MCAA (Exs. 2-95) also commented that it would 
endeavor to develop training aid programs for its membership. OSHA 
encourages these groups and appreciates their efforts to develop 
training programs.
    The Agency is adding a new paragraph (b) to final rule 
Sec. 1926.503 to require employers to verify that employees have been 
trained as required by paragraph (a). In particular, final rule 
paragraph (b)(1) requires employers to prepare a written certification 
record. Final rule paragraph (b)(1) further specifies that the written 
certification record shall contain the name or other identity of the 
employee trained, the date(s) of the training, and the signature of the 
person who conducted the training or the signature of the employer.
    As noted above, OSHA does not require retraining provided the 
employee can demonstrate the ability to recognize the hazards of 
falling and the procedures to be followed to minimize fall hazards as 
required by paragraph (a). OSHA recognizes that in many cases an 
employer will be unable to identify the date on which the previous 
training was provided. Accordingly, when employers relying on previous 
training prepare their certification records, they shall indicate the 
date the employer determined the prior training was adequate rather 
than the date of actual training.
    The certification record can be prepared in any format an employer 
chooses, including preprinted forms, computer generated lists, or 3 x 5 
cards.
    OSHA recognizes that many employers have already been providing 
affected employees with training that complies with final rule 
Secs. 1926.503(a) and that requiring those employers to repeat the 
pertinent training would be unreasonably burdensome.
    Paragraph (b)(2) requires that the latest certification record be 
maintained.
    These provisions, which were not proposed, have been added because, 
based on the discussion of the need for training records in Issue #5 
and the response to that Issue, OSHA has determined that verification 
of training through a written certification is reasonably necessary for 
the protection of employees.
    The AGC (Exs. 2-16, 2-47 and 2-92) and the ABC (Ex. 2-51) stated 
that a requirement for training records would be unreasonably 
burdensome. Bristol Steel and the NEA (Exs. 2-12 and 2-43) stated 
``[w]ritten training records should not be required, and the proposed 
standard does not require any. Preparation and maintenance of * * * 
records could easily require 0.05 to 0.2 manhours per employee per 
year, at a cost of $2.00 to $10.00 per employee, and would not further 
the objectives of accident prevention.'' The NCA (Ex. 2-45) simply 
stated [c]ompliance with training requirements should not include OSHA 
recordkeeping requirements.
    On the other hand, the State of Maryland (Ex. 2-31) stated 
``[t]raining program should be documented as to attendance and subjects 
reviewed.'' In addition, the BCMALU (Ex. 2-46) stated ``[t]raining 
could be marked on an Individuals payroll sheet or whatever, it should 
be no big bookkeeping problem and the cost is minor compared to the 
work produced, when you are confident it is safe and reduced Insurance 
rates.''
    OSHA has determined, after careful review of these comments, that 
some record of training is needed to provide assurance that the 
required training has, in fact, been provided. Given the performance-
oriented focus of this rulemaking, the Agency has determined that the 
generation and review of extensive documentation would impose 
unnecessary burdens. Accordingly, OSHA will require verification of 
training through a certification which contains the above-listed 
information.
    The Agency notes that OSHA has also required certification of 
training in the personal protective equipment standard for general 
industry, Sec. 1910.132(f)(4); the permit-required confined space 
standard, Sec. 1910.146(g)(4); the control of hazardous energy 
(lockout/tagout) standard, Sec. 1910.147(c)(7)(iv); and in the 
Telecommunications standard, Sec. 1910.268(c). OSHA also notes that the 
preparation of a certification will not preclude a citation if the 
Agency determines that employees have not, in fact, been trained. The 
Agency believes that this provision will impose a minimal burden, while 
enabling the employer and OSHA to verify the status of training 
efforts.
    As stated in Sec. 1926.503(c), fall protection training must be 
repeated when changes in workplace conditions or changes in the types 
of fall protection systems or equipment to be used render previous 
training obsolete, and when inadequacies in an affected employee's 
knowledge or use of fall protection systems or equipment indicate that 
the employee has not retained the understanding or skill required by 
paragraph (a). This provision is similar to the proposed provision but 
has been revised to indicate clearly that employers have an ongoing 
responsibility to maintain employee proficiency in the use and care of 
fall protection equipment.
Appendices A to E
    The final rule adds five appendices (discussed below), to revised 
subpart M. The proposed rule contained only three appendices. 
Appendices D, and E were not proposed, but have been added to give 
clarification and examples of how to comply with certain requirements. 
These Appendices are non-mandatory, and neither impose additional 
requirements nor detract from the requirements contained in this 
subpart. They are intended to provide useful, explanatory material and 
information to employers and employees to assist them in compliance 
with the standards.
Appendix A to Subpart M--Roof Widths
    This appendix is provided to serve as a guide to assist employers 
in complying with the requirements of Sec. 1926.501(b)(10). This 
appendix is non-mandatory. The record compiled for the promulgation of 
existing Sec. 1926.500(g), which requires the guarding of low-pitched 
roofs during the performance of roofing work, demonstrated that there 
was confusion as to which dimension of a building should be considered 
to be the width of a roof. This appendix explains that in all cases 
buildings are viewed in plan view (i.e., viewed from above, looking 
down). The width of the roof is then the narrower of the two primary 
dimensions which define the roof area. Although the Appendix does not 
show all possible roof configurations, it does give some common 
arrangements. Final Appendix A is unchanged from the proposed Appendix 
A. There were no comments on proposed Appendix A.
Appendix B to Subpart M--Guardrail Systems
    As explained in the discussion of Sec. 1926.502(b) governing 
guardrail systems, this appendix is a non-mandatory set of guidelines 
provided to assist employers in complying with the requirements of 
Sec. 1926.502(b) (3), (4) and (5). An employer may use these guidelines 
as a starting point for designing guardrail systems. However, the 
guidelines do not provide all the information necessary to build a 
complete system, and the employer is still responsible for designing 
and assembling these components in such a way that the completed system 
will meet the requirements of the standard. Components for which no 
specific guidelines are given in the appendix (e.g., joints, base 
connections, components made with other materials, and components with 
other dimensions) must also be designed and constructed in such a way 
that the completed system will meet the requirements of 
Sec. 1926.502(b) (3), (4) and (5). Final Appendix B is unchanged from 
the proposed Appendix B. There were no comments on proposed Appendix B.
Appendix C to Subpart M--Personal Fall Arrest Systems
    Appendix C is provided to serve as a guide to assist employers in 
complying with the test requirements of paragraph Sec. 1926.502(d) and 
Sec. 1926.502(e). Personal fall arrest systems and positioning device 
systems which have been tested in accordance with the criteria of this 
non-mandatory appendix will be deemed by OSHA to meet the performance 
criteria of paragraphs Sec. 1926.502(d)(16) and Sec. 1926.502(e) (3) 
and (4). Appendix C also provides additional non-mandatory guidelines 
for personal fall arrest systems. Final Appendix C differs from the 
proposed Appendix C in that it provides additional information 
consistent with the guidelines provided in the appendix for powered 
platforms.
Appendix D to Subpart M--Positioning Device Systems
    Appendix D is a new appendix which has been added to the final rule 
to complement Appendix C and provide additional information on testing 
methods for positioning device systems. Appendix D also contains 
guidelines for inspecting positioning device systems to assist in 
complying with the requirements of Sec. 1926.502(e)(5).
Appendix E to Subpart M--Sample Fall Protection Plans
    This is a new Appendix to the final rule and has been added to 
assist employers who are able to demonstrate that the use of 
conventional fall protection measures are infeasible or create a 
greater hazard when constructing leading edges, or erecting precast 
concrete structures, or when engaged in residential construction work. 
The plans in Appendix E were developed specifically for a precast 
concrete worksite and a residential construction site, and can be 
modified and tailored for use in the other areas where OSHA permits 
employers to develop a Fall Protection Plans (See Sec. 1926.501(b)(2), 
(b)(12) and (b)(13).

Discussion of Specific Issues Raised in the Proposed Rule

    In the proposed rule, OSHA raised 27 specific issues. The comments 
and testimony received in response to issues that address specific 
provisions of the final rule are discussed above with those provisions. 
The other, more general issues are discussed below, along with the 
Agency's decisions with respect to those issues.
    In Issue #1, OSHA asked for public comment on the extent to which 
current practices would meet the proposed rule; the feasibility and 
utility of the proposed rule; and any costs or benefits of the proposed 
rule not addressed by OSHA. OSHA also asked for any accident reports 
which indicated that the proposal did not properly address fall 
hazards.
    In response, OSHA received a variety of comments, some which took 
exception to OSHA's estimate of the number of construction workers who 
die each year from falls at construction sites. Other comments 
reflected commenters thoughts and opinions on the practicality and 
feasibility of the proposed rule. For example, with regard to OSHA's 
estimate that 45-60 workers are killed on construction jobs each year, 
one commenter (Ex. 2-36) stated his belief that the actual number 
killed was higher because, he noted, the National Safety Council's 
Accident Facts and insurance data which indicated that construction and 
scaffold falls may approach 1,000 per year. The commenter also included 
a copy of an article in which a representative of one union of 
construction workers stated that in one year 41 of their members alone 
were killed due to falls.
    Another commenter, Terry Schmidt, Chairman of the ANSI Z359 
Committee (Ex. 2-50) stated, ``There is evidence to suggest that OSHA's 
estimate of 45-60 fatal falls per year in construction is perhaps 
erroneously very low.'' The point being made by these commenters is 
that the number of workers killed in falls each year is higher than 
that which OSHA estimated at the time of proposal and that a fall 
protection rule would, therefore, achieve additional benefits in that 
more lives would be saved.
    With regard to OSHA question on costs, the Great Lakes Fabricators 
& Erectors Association (Ex. 2-19) commented that the regulations, as 
proposed, provided sufficient protection at reasonable cost levels.
    With regard to current practices in the industry and on feasibility 
and utility of the proposed rule, the National Constructors Association 
(NCA) (Ex. 2-45), commented that the current level of practice which 
meets the requirements of the proposed changes is minimal to non-
existent. They also stated, ``The feasibility is questionable 
especially with the requirements for floor covering and extending 
perimeter nets to 15 feet,'' and noted that costs would increase to 
provide the proposed safety measures.
    The United Union of Roofers, Waterproofers, and Allied Workers (Ex. 
2-99) said, ``The use of fall protection in the roofing industry is at 
best minimal.''
    Bristol Steel and NEA (Ex. 2-12 and 2-43) commented that the 
proposed standards generally reflected current accepted practices.
    OSHA concludes, based on the record and as discussed above, that 
the final rule will have the effect of significantly reducing the risk 
of death or injury to workers. OSHA also concludes that the final rule 
will result in greater compliance than currently exist. Therefore, OSHA 
has decided promulgation of this final rule is necessary.
    In Issue #3, OSHA noted that in some of the existing and proposed 
provisions, it had used specific numerical limits to define and clarify 
various duties. As an example, OSHA noted that Sec. 1926.502(a) of the 
existing rule and Sec. 1926.500(b) of the proposed rule defined the 
term ``hole'' by giving a physical measurement. This measurement was 
then used to determine when certain safety systems must be used to 
protect against fall hazards. These and other limits were based on 
existing requirements and national consensus standards, and were used 
in lieu of more performance-oriented language such as ``covers shall be 
used on all holes which are large enough to constitute a fall hazard,'' 
or language which requires a numerical limit but then allows other 
configurations which give ``equivalent'' protection. OSHA believes that 
the use of specific limits in certain provisions is necessary to 
provide notice to employers as to how they can comply with a provision 
and how OSHA intends to enforce the provision. OSHA has attempted to 
restrict the use of such limits in the final rule to situations where 
it is necessary to specify a single criterion for employee protection, 
to promote consistency in hazard abatement, and to minimize legal 
disputes over the intent of the requirement.
    Issue #3 requested comment on the appropriateness of using 
specification language as opposed to a non-mandatory appendix for 
guidance of employers. OSHA also requested that if the specification 
language was not appropriate, that commenters state how the provisions 
should be written to provide the desired flexibility and the required 
fair notice. If commenters felt the continued use of such limits to be 
appropriate, they were asked to comment on whether the proposed limits 
were sufficient to abate the hazards. Commenters were also requested to 
include appropriate cost and injury data.
    In response to this issue, several commenters agreed that OSHA's 
use of specification language was appropriate (Exs. 2-12, 2-36, 2-46 2-
50, 2-56, 2-89, and 2-99). Other commenters (Exs. 2-16, 2-45, 2-47, 2-
51, 2-92, 2-103, and 2-140) noted that performance-oriented language 
with non-mandatory appendices was preferred, though they did not 
recommend that any particular specification type language be rewritten. 
ACCSH (Tr. 6/10/87; p. 67), on the other hand, recommended that 
specification language be used in Subpart M and that the specifications 
be included in the body of the standard rather than the appendix.
    After careful consideration of the record on this issue, OSHA has 
determined that there are some instances where OSHA regulations must be 
specific, such as when defining the dimensions of a hole, and that 
there are other instances where performance language is more 
appropriate, such as where OSHA can identify the hazard, state the 
desired results, and leave it up to the employer to choose the 
appropriate method for eliminating or reducing the hazard. OSHA 
believes that the final rule is neither too specific nor so 
performance-oriented that employers will have difficulty in complying 
with the final rule. OSHA has not made any revisions based solely on 
the comments received in response to this issue.

    In Issue #27, OSHA noted that Subpart V--Power Transmission and 
Distribution provided additional criteria for personal climbing 
equipment, lineman's body belts, safety straps and lanyards. OSHA also 
noted that paragraph Sec. 1926.951(b)(4) required lanyards and 
lifelines to meet the requirements in the existing rule at 
Sec. 1926.104, Safety belts, lifelines, and lanyards. Public comment 
was requested on the economic impact, and any other impact, that would 
result if the reference to Sec. 1926.104 were changed to 
Sec. 1926.502(d)--Personal fall arrest systems and Sec. 1926.502(e)--
Positioning device systems.
    All the commenters who responded to the questions raised in this 
issue indicated that there would be no impact, economic or otherwise, 
as a result of the OSHA contemplated changes, and they agreed that the 
reference should be changed. (Exs. 2-12, 2-27, 2-43 and 2-50). OSHA 
agrees with the commenters and has revised the provision in 
Sec. 1926.951(b)(4) to require lifeline and lanyards to be in 
compliance with Sec. 1926.502.

Discussion of Issues Raised in the Notice of Hearing

    On January 26, 1988, OSHA published a Notice of Hearing in the 
Federal Register [53 FR 2048]. In that Notice, OSHA raised four new 
issues specific to the proposed rule on fall protection. Those issues 
involved steel erection, precast concrete, guardrail systems and safety 
net systems. The comments received on these issues have already been 
discussed except Issue M-1 on Steel Erection in which OSHA raised a 
number of concerns which related to fall protection measures for the 
employees engaged in steel erection activities. OSHA received 
considerable data primarily through testimony and post hearing comments 
concerning the subjects addressed in Issue M-1 and M-2. Comments 
related to the construction of buildings are not discussed in this 
final rule since the information was intended for use at a later date 
as OSHA stated in the hearing notice. OSHA recently established the 
Steel Erection Negotiated Rulemaking Advisory Committee (SENRAC) to 
assist the Agency in developing a proposed revision of subpart R--Steel 
Erection, which includes fall protection requirements for employees 
performing steel erection work in buildings (59 FR 24389; May 11, 
1994). The comments received in response to Issue #1 and #2 have been 
made a part of the record of this new rulemaking. Final Subpart M does 
not set the duty to provide fall protection for workers engaged in 
steel erection of buildings. The requirements of Sec. 1926.105(a), 
which is being deleted from part 1926 in this rulemaking, will continue 
to apply to steel erection of buildings until subpart R is revised. 
Because the requirements of that section will now apply only to steel 
erection of buildings, OSHA is redesignating Sec. 1926.105(a) as 
Sec. 1926.753 of subpart R. This requirement for employees to have fall 
protection outside (at the perimeter) of buildings, complements the 
requirements already in subpart R which require fall protection inside 
the buildings. Together, these requirements will maintain continuity of 
coverage for these workers until subpart R is revised. Fall protection 
requirements for activities involving steel erection other than 
buildings, such as the erection of bridges and tanks are, of course, 
not currently addressed in subpart R. Therefore, subpart M will set the 
requirements to have fall protection in these other areas.
    In Issue #2 of the notice of hearing, OSHA asked if there were 
areas or operations, in addition to those already identified in 
proposed Sec. 1926.501, which had unique fall protection requirements 
not addressed by the proposed standards. OSHA requested commenters to 
describe such areas and operations in detail and to discuss the fall 
protection systems which should be used.
    OSHA received many responses to Issue #2. The largest number of 
commenters mentioned steel erection as an activity that was so unique 
that it should have separate fall protection requirements. (Exs. 2-16, 
2-27, 2-45, 2-47, 2-51, and 2-92). Some commenters suggested that the 
requirements be placed in a separate subpart of the construction safety 
and health standards; namely, subpart R--Steel Erection. Others (Exs. 
2-12, 2-36, and 2-43) commented that the proposed standards were 
adequate for all structural erection operations, and pointed out how 
the leading edge requirements might apply to structural erection work.
    In addition, testimony given at the public hearing supported the 
need to address fall protection for steel erection separately. OSHA's 
decision that fall protection for workers engaged in steel erection 
activities will be the subject of a separate rulemaking effort was 
discussed in the hearing notice for Subpart M issued on January 26, 
1988, [53 FR 2052].

IV. Summary of the Regulatory Impact Analysis

Introduction

    Executive Order 12866 and the Regulatory Flexibility Act required 
OSHA to analyze the costs, benefits, and other consequences and impacts 
associated with this standard. Consistent with these requirements, OSHA 
has prepared a regulatory impact analysis for revised subpart M. The 
following is a summary of this analysis, which is available from OSHA's 
docket office.
    The regulatory impact analysis includes a description of the 
industries affected by the regulation, the evaluation of the risks 
addressed, the assessment of the benefits attributable to the revised 
standard, the determination of the technological feasibility of new 
requirements, the estimation of the costs of compliance with subpart M 
requirements, the determination of the economic feasibility of 
compliance with the standard, and the analysis of the economic and 
other impacts associated with this rulemaking.

Affected Industries

    The requirements of revised subpart M apply to all establishments 
in the construction industry. As classified by the 1987 Standard 
Industrial Classification (SIC) manual, the industry can be divided 
into three broad types of activities: building construction general 
contractors (SIC 15), heavy construction general and special trade 
contractors (SIC 16) and construction by other special trade 
contractors (SIC 17).
    The total value of construction work is approximately $500 billion 
annually. About 75 percent of this amount ($370 billion) involves the 
construction of buildings, including single family houses ($124 
billion). The total value of nonbuilding construction work includes $45 
billion for the construction of highways, streets, parking areas, 
bridges, and tunnels, and another $13 billion for the construction of 
sewers and water mains.
    Construction work includes new construction as well as additions, 
alterations, reconstruction, maintenance, and repairs. Of the total 
value of construction work of $500 billion, about $328 billion (66 
percent) involves new construction.

Evaluation of Risk and Potential Benefits

    Of the 115,000 injuries due to falls that occur in the construction 
industry annually, 68,000 are addressed by the subpart M standard while 
the remaining 47,000 are attributable to circumstances addressed by 
standards other than subpart M. Injuries and fatalities due to falls in 
construction that are not covered by subpart M include falls that are 
not associated with subpart M criteria for fall protection systems 
(Sec. 1926.502) and involve ladders, stairs, scaffolds, vehicles, and 
skeletal steel erection of buildings. Similarly, of the 158 fatalities 
due to falls in construction annually, 95 are covered by provisions of 
the revised subpart M standard.
    Revisions to subpart M promulgated through this rulemaking are 
expected to result in the prevention of 22 fatalities and 15,600 
injuries annually in addition to the fatalities and injuries that would 
be prevented through full compliance with the existing standard. Most 
of the falls in construction addressed by subpart M could be prevented 
through compliance with the existing as well as with the revised 
standards.
    In addition to the unquantifiable reductions in pain and suffering, 
the prevention of injuries will result in estimated savings of over 
$200 million annually. This estimate includes savings related to wage 
and productivity losses, medical costs, administrative expenses, and 
other costs associated with accidents.

Technological Feasibility

    Since the requirements of the revised subpart M can be met with 
existing equipment and methods that are readily available, the standard 
is considered to be technologically feasible.

Costs

    The total estimated costs associated with new requirements included 
in the revised subpart M standard amount to about $40 million annually. 
The majority of these costs ($25 million) involve costs associated with 
providing increased fall protection for employees working on roofs. 
Other components of the estimated compliance costs involve inspections 
and tests of personnel safety nets ($5.4 million), and additional 
training for employees exposed to fall hazards ($6.6 million).

Economic Impacts

    Compliance with the requirements of the revised subpart M standard 
has been determined to be economically feasible and is not expected to 
produce any significant adverse economic impacts. The costs that are 
imposed by the regulation should be a minimal burden on construction 
establishments. The estimated compliance costs represent less than 0.01 
percent of total construction revenues and less than 0.5 percent of 
revenues for each individual construction sector.

Regulatory Flexibility Analysis

     Pursuant to the Regulatory Flexibility Act, OSHA has made an 
assessment of the impact of the revised standard and has concluded that 
it will not have a significant impact upon a substantial number of 
small entities. The estimated compliance costs do not involve large 
capital expenditures, and there is no significant differential effect 
on small firms relative to that on large firms.
    OSHA has included non-mandatory appendices as part of the 
regulation to help improve compliance with the standard and reduce the 
potential for misunderstanding. These appendices will also help to 
minimize impacts on small firms by significantly reducing the effort 
needed to develop a compliance strategy.

V. Statutory Considerations

A. Introduction

    OSHA has described fall hazards, falling object hazards and the 
measures required to protect affected employees from those hazards in 
Section I, Background; Section II, Hazards Involved; and Section III, 
Summary and Explanation of the Final Rule, above. The Agency is 
providing the following discussion of the statutory mandate for OSHA 
rulemaking activity to explain the legal basis for its determination 
that the revised fall protection standard, as promulgated, is 
reasonably necessary to protect affected employees from significant 
risks of injury and death.
    Section 2(b)(3) of the Occupational Safety and Health Act 
authorizes ``the Secretary of Labor to set mandatory occupational 
safety and health standards applicable to businesses affecting 
interstate commerce'', and section 5(a)(2) provides that ``[e]ach 
employer shall comply with occupational safety and health standards 
promulgated under this Act'' (emphasis added). Section 3(8) of the OSH 
Act (29 U.S.C. Sec. 652(8)) provides that ``the term 'occupational 
safety and health standard' means a standard which requires conditions, 
or the adoption or use of one or more practices, means, methods, 
operations, or processes, reasonably necessary or appropriate to 
provide safe or healthful employment and places of employment.''
    In two recent cases, reviewing courts have expressed concern that 
OSHA's interpretation of these provisions of the OSH Act, particularly 
of section 3(8) as it pertains to safety rulemaking, could lead to 
overly costly or under-protective safety standards. In International 
Union, UAW v. OSHA, 938 F.2d 1310 (D.C. Cir. 1991), the District of 
Columbia Circuit rejected substantive challenges to OSHA's lockout/
tagout standard and denied a request that enforcement of that standard 
be stayed, but it also expressed concern that OSHA's interpretation of 
the OSH Act could lead to safety standards that are very costly and 
only minimally protective. In National Grain & Feed Ass'n v. OSHA, 866 
F.2d 717 (5th Cir. 1989), the Fifth Circuit concluded that Congress 
gave OSHA considerable discretion in structuring the costs and benefits 
of safety standards but, concerned that the grain dust standard might 
be under-protective, directed OSHA to consider adding a provision that 
might further reduce significant risk of fire and explosion.
    OSHA rulemakings involve a significant degree of agency expertise 
and policy-making discretion to which reviewing courts must defer. 
(See, for example, Building & Constr. Trades Dep't, AFL-CIO v. Brock, 
838 F.2d 1258, 1266 (D.C. Cir. 1988); Industrial Union Dep't, AFL-CIO 
v. American Petroleum Inst., 448 U.S. 607, 655 n. 62 (1980).) At the 
same time, the Agency's technical expertise and policymaking authority 
must be exercised within discernable limits. The lockout/tagout and 
grain handling standard decisions sought clarification of the Agency's 
view of the scope of its expertise and authority. In light of those 
decisions, the preamble to this safety standard states OSHA's views 
regarding the limits of its safety rulemaking authority and explains 
why the Agency is confident that its interpretive views have in the 
past avoided regulatory extremes and continue to do so in this rule.
    Stated briefly, the OSH Act requires that, before promulgating any 
occupational safety standard, OSHA demonstrate based on substantial 
evidence in the record as a whole that: (1) the proposed standard will 
substantially reduce a significant risk of material harm; (2) 
compliance is technologically feasible in the sense that the protective 
measures being required already exist, can be brought into existence 
with available technology, or can be created with technology that can 
reasonably be developed; (3) compliance is economically feasible in the 
sense that industry can absorb or pass on the costs without major 
dislocation or threat of instability; and (4) the standard is cost 
effective in that it employs the least expensive protective measures 
capable of reducing or eliminating significant risk. Additionally, 
proposed safety standards must be compatible with prior Agency action, 
must be responsive to significant comment in the record, and, to the 
extent allowed by statute, must be consistent with applicable Executive 
Orders. These elements limit OSHA's regulatory discretion for safety 
rulemaking and provide a decision- making framework for developing a 
rule.

B. Congress Concluded That OSHA Regulations are Necessary To Protect 
Workers From Occupational Hazards and That Employers Should Be Required 
To Reduce or Eliminate Significant Workplace Health and Safety Threats

    At section 2(a) of the OSH Act (29 U.S.C. 651(a)), Congress 
announced its determination that occupational injury and illness should 
be eliminated as much as possible: ``The Congress finds that 
occupational injury and illness arising out of work situations impose a 
substantial burden upon, and are a hindrance to, interstate commerce in 
terms of lost production, wage loss, medical expenses, and disability 
compensation payments.'' Congress therefore declared ``it to be its 
purpose and policy * * * to assure so far as possible every working man 
and woman in the Nation safe * * * working conditions [29 U.S.C. 
651(b)].''
    To that end, Congress instructed the Secretary of Labor to adopt 
existing federal and consensus standards during the first two years 
after the OSH Act became effective and, in the event of conflict among 
any such standards, to ``promulgate the standard which assures the 
greatest protection of the safety or health of the affected employees 
[29 U.S.C. 655(a)].'' Congress also directed the Secretary to set 
mandatory occupational safety standards [29 U.S.C. 651(b)(3)], based on 
a rulemaking record and substantial evidence [29 U.S.C. 655(b)(2)], 
that are ``reasonably necessary or appropriate to provide safe * * * 
employment and places of employment.'' When promulgating permanent 
safety or health standards that differ from existing national consensus 
standards, the Secretary must explain ``why the rule as adopted will 
better effectuate the purposes of this Act than the national consensus 
standard [29 U.S.C. 655(b)(8)].'' Correspondingly, every employer must 
comply with OSHA standards and, in addition, ``furnish to each of his 
employees employment and a place of employment which are free from 
recognized hazards that are causing or are likely to cause death or 
serious physical harm to his employees [29 U.S.C. 654(a)].''
    ``Congress understood that the Act would create substantial costs 
for employers, yet intended to impose such costs when necessary to 
create a safe and healthful working environment. Congress viewed the 
costs of health and safety as a cost of doing business * * *. Indeed, 
Congress thought that the financial costs of health and safety problems 
in the workplace were as large as or larger than the financial costs of 
eliminating these problems [American Textile Mfrs. Inst. Inc. v. 
Donovan, 452 U.S. 490, 519-522 (1981) (ATMI); emphasis was supplied in 
original].'' ``[T]he fundamental objective of the Act [is] to prevent 
occupational deaths and serious injuries [Whirlpool Corp. v. Marshall, 
445 U.S. 1, 11 (1980)].'' ``We know the costs would be put into 
consumer goods but that is the price we should pay for the 80 million 
workers in America [S. Rep. No. 91-1282, 91st Cong., 2d Sess. (1970); 
H.R. Rep. No. 91-1291, 91st Cong., 2d Sess. (1970), reprinted in Senate 
Committee on Labor and Public Welfare, Legislative History of the 
Occupational Safety and Health Act of 1970, (Committee Print 1971) 
(``Leg. Hist.'') at 444 (Senator Yarborough)].'' ``Of course, it will 
cost a little more per item to produce a washing machine. Those of us 
who use washing machines will pay for the increased cost, but it is 
worth it, to stop the terrible death and injury rate in this country 
[Id. at 324; see also 510-511, 517].''

    [T]he vitality of the Nation's economy will be enhanced by the 
greater productivity realized through saved lives and useful years 
of labor.
    When one man is injured or disabled by an industrial accident or 
disease, it is he and his family who suffer the most immediate and 
personal loss. However, that tragic loss also affects each of us. As 
a result of occupational accidents and disease, over $1.5 billion in 
wages is lost each year [1970 dollars], and the annual loss to the 
gross national product is estimated to be over $8 billion. Vast 
resources that could be available for productive use are siphoned 
off to pay workmen's compensation and medical expenses * * *.
    Only through a comprehensive approach can we hope to effect a 
significant reduction in these job death and casualty figures. [Id. 
at 518-19 (Senator Cranston)]

    Congress considered uniform enforcement crucial because it would 
reduce or eliminate the disadvantage that a conscientious employer 
might experience where inter-industry or intra-industry competition is 
present. Moreover, ``many employers--particularly smaller ones--simply 
cannot make the necessary investment in health and safety, and survive 
competitively, unless all are compelled to do so [Leg. Hist. at 144, 
854, 1188, 1201].''
    Thus, the statutory text and legislative history make clear that 
Congress conclusively determined that OSHA regulation is necessary to 
protect workers from occupational hazards and that employers should be 
required to reduce or eliminate significant workplace health and safety 
threats.

C. As Construed By the Courts and By OSHA, the OSH Act Sets Clear and 
Reasonable Limits for Agency Rulemaking Action

    OSHA has long followed the teaching that section 3(8) of the OSH 
Act requires that, before it promulgates ``any permanent health or 
safety standard, [it must] make a threshold finding that a place of 
employment is unsafe--in the sense that significant risks are present 
and can be eliminated or lessened by a change in practices [Industrial 
Union Dep't, AFL-CIO v. American Petroleum Inst., 448 U.S. 607, 642 
(1980) (plurality) (Benzene); emphasis was supplied in original].'' 
Thus, the national consensus and existing federal standards that 
Congress instructed OSHA to adopt summarily within two years of the OSH 
Act's inception provide reference points concerning the least an OSHA 
standard should achieve (29 U.S.C. Secs. 655(a)). As a result, OSHA is 
precluded from regulating insignificant risks or from issuing standards 
that do not at least lessen risk in a significant way.
    The OSH Act also limits OSHA's discretion to issue overly 
burdensome rules, as the Agency also has long recognized that ``any 
standard that was not economically or technologically feasible would a 
fortiori not be `reasonably necessary or appropriate' under the Act. 
See Industrial Union Dep't v. Hodgson, [499 F.2d 467, 478 (D.C. Cir. 
1974)] (`Congress does not appear to have intended to protect employees 
by putting their employers out of business.') [American Textile Mfrs. 
Inst. Inc., 452 U.S. at 513 n. 31 (a standard is economically feasible 
even if it portends `disaster for some marginal firms,' but it is 
economically infeasible if it `threaten[s] massive dislocation to, or 
imperil[s] the existence of,' the industry)].''
    By stating the test in terms of ``threat'' and ``peril,'' the 
Supreme Court made clear in ATMI that economic infeasibility begins 
short of industry-wide bankruptcy. OSHA itself has placed the line 
considerably below this level. (See for example, ATMI, 452 U.S. at 527 
n. 50; 43 FR 27,360 (June 23, 1978). Proposed 200 g/m\3\ PEL 
for cotton dust did not raise serious possibility of industry-wide 
bankruptcy, but impact on weaving sector would be severe, possibly 
requiring reconstruction of 90 percent of all weave rooms. OSHA 
concluded that the 200 g/m\3\ level was not feasible for 
weaving and that 750 g/m\3\ was all that could reasonably be 
required). See also 54 FR 29,245-246 (July 11, 1989); American Iron & 
Steel Institute, 939 F.2d at 1003. OSHA raised engineering control 
level for lead in small nonferrous foundries to avoid the possibility 
of bankruptcy for about half of small foundries even though the 
industry as a whole could have survived the loss of small firms.) All 
OSHA standards must also be cost-effective in the sense that the 
protective measures being required must be the least expensive measures 
capable of achieving the desired end (ATMI, at 514 n. 32; Building and 
Constr. Trades Dep't, AFL-CIO v. Brock, 838 F.2d 1258, 1269 (D.C. Cir. 
1988)). OSHA gives additional consideration to financial impact in 
setting the period of time that should be allowed for compliance, 
allowing as much as ten years for compliance phase-in. (See United 
Steelworkers of Am. v. Marshall, 647 F.2d 1189, 1278 (D.C. Cir. 1980), 
cert. denied, 453 U.S. 913 (1981).) Additionally, OSHA's enforcement 
policy takes account of financial hardship on an individualized basis. 
OSHA's Field Operations Manual provides that, based on an employer's 
economic situation, OSHA may extend the period within which a violation 
must be corrected after issuance of a citation (CPL. 2.45B, Chapter 
III, paragraph E6d(3)(a), Dec. 31, 1990).
    To reach the necessary findings and conclusions, OSHA conducts 
rulemaking in accordance with the requirements of section 6 of the OSH 
Act. The rulemaking process enables the Agency to determine the 
qualitative and, if possible, the quantitative nature of the risk with 
(and without) regulation, the technological feasibility of compliance, 
the availability of capital to the industry and the extent to which 
that capital is required for other purposes, the industry's profit 
history, the industry's ability to absorb costs or pass them on to the 
consumer, the impact of higher costs on demand, and the impact on 
competition with substitutes and imports. (See ATMI at 2501-2503; 
American Iron & Steel Institute generally.) Section 6(f) of the OSH Act 
further provides that, if the validity of a standard is challenged, 
OSHA must support its conclusions with ``substantial evidence in the 
record considered as a whole,'' a standard that courts have determined 
requires fairly close scrutiny of agency action and the explanation of 
that action. (See Steelworkers, 647 F.2d at 1206-1207.)
    OSHA's powers are further circumscribed by the independent 
Occupational Safety and Health Review Commission, which provides a 
neutral forum for employer contests of citations issued by OSHA for 
noncompliance with health and safety standards (29 U.S.C. Secs. 659-
661; noted as an additional constraint in Benzene at 652 n. 59). OSHA 
must also respond rationally to similarities and differences among 
industries or industry sectors. (See Building and Constr. Trades Dep't, 
AFL-CIO v. Brock, 838 F.2d 1258, 1272-73 (D.C. Cir. 1988).)
    OSHA rulemaking is thus constrained first by the need to 
demonstrate that the standard will substantially reduce a significant 
risk of material harm, and then by the requirement that compliance is 
technologically capable of being done and not so expensive as to 
threaten economic instability or dislocation for the industry. Within 
these bounds, further constraints such as the need to find cost-
effective measures and to respond rationally to all meaningful comment 
militate against regulatory extremes.

D. The Revised Fall Protection Standard Complies With the Statutory 
Criteria Described Above and is not Subject to the Additional 
Constraints Applicable to Section 6(b)(5) Standards

    Standards which regulate hazards that are frequently undetectable 
because they are subtle or develop slowly or after long latency 
periods, are frequently referred to as ``health'' standards. Standards 
that regulate hazards, such as falls, explosions or electrocutions, 
that cause immediately noticeable physical harm, are called ``safety'' 
standards. (See National Grain & Feed Ass'n v. OSHA (NGFA II), 866 F.2d 
717, 731, 733 (5th Cir. 1989). As noted above, section 3(8) provides 
that all OSHA standards must be ``reasonably necessary or 
appropriate.'' In addition, section 6(b)(5) requires that OSHA set 
health standards which limit significant risk ``to the extent 
feasible.'' OSHA has determined that the revised fall protection 
standard is a safety standard, because the revised standard addresses 
hazards, such as falls from elevations and falling objects, that are 
immediately dangerous to life or health, not the longer term, less 
obvious hazards subject to section 6(b)(5).
    The OSH Act and its legislative history clearly indicate that 
Congress intended for OSHA to distinguish between safety standards and 
health standards. For example in section 2(b)(6) of the OSH Act, 
Congress declared that the goal of assuring safe and healthful working 
conditions and preserving human resources would be achieved, in part:

* * * by exploring ways to discover latent diseases, establishing 
causal connections between diseases and work in environmental 
conditions, and conducting other research relating to health 
problems, in recognition of the fact that occupational health 
standards present problems often different from those involved in 
occupational safety.

    The legislative history makes this distinction even clearer:

    [The Secretary] should take into account that anyone working in 
toxic agents and physical agents which might be harmful may be 
subjected to such conditions for the rest of his working life, so 
that we can get at something which might not be toxic now, if he 
works in it a short time, but if he works in it the rest of his life 
might be very dangerous; and we want to make sure that such things 
are taken into consideration in establishing standards. [Leg. Hist. 
at 502-503 (Sen. Dominick), quoted in Benzene at 648-49]
     Additionally, Representative Daniels distinguished between 
``insidious `silent killers' such as toxic fumes, bases, acids, and 
chemicals'' and ``violent physical injury causing immediate visible 
physical harm'' (Leg. Hist. at 1003), and Representative Udall 
contrasted insidious hazards like carcinogens with ``the more visible 
and well-known question of industrial accidents and on-the-job injury'' 
(Leg. Hist. at 1004). (See also, for example, S.Rep. No. 1282, 91st 
Cong., 2d Sess 2-3 (1970), U.S. Code Cong. & Admin. News 1970, pp. 
5177, 5179, reprinted in Leg. Hist. at 142-43, discussing 1967 Surgeon 
General study that found that 65 percent of employees in industrial 
plants ``were potentially exposed to harmful physical agents, such as 
severe noise or vibration, or to toxic materials''; Leg.Hist at 412; 
id. at 446; id. at 516; id. at 845; International Union, UAW at 1315.)
    In reviewing OSHA rulemaking activity, the Supreme Court has held 
that section 6(b)(5) requires OSHA to set ``the most protective 
standard consistent with feasibility'' (Benzene at 643 n. 48). As 
Justice Stevens observed:

    The reason that Congress drafted a special section for these 
substances * * * was because Congress recognized that there were 
special problems in regulating health risks as opposed to safety 
risks. In the latter case, the risks are generally immediate and 
obvious, while in the former, the risks may not be evident until a 
worker has been exposed for long periods of time to particular 
substances. [Benzene, at 649 n. 54.]

    Challenges to the grain dust and lockout/tagout standards included 
assertions that grain dust in explosive quantities and uncontrolled 
energy releases that could expose employees to crushing, cutting, 
burning or explosion hazards were harmful physical agents so that OSHA 
was required to apply the criteria of section 6(b)(5) when determining 
how to protect employees from those hazards. Reviewing courts have 
uniformly rejected such assertions. For example, the Court in 
International Union, UAW v. OSHA, 938 F.2d 1310 (D.C. Cir. 1991) 
rejected the view that section 6(b)(5) provided the statutory criteria 
for regulation of uncontrolled energy, holding that such a ``reading 
would obliterate a distinction that Congress drew between `health' and 
`safety' risks.'' The Court also noted that the language of the OSH Act 
and the legislative history supported the OSHA position (International 
Union, UAW at 1314). Additionally, the Court stated: ``We accord 
considerable weight to an agency's construction of a statutory scheme 
it is entrusted to administer, rejecting it only if unreasonable'' 
(International Union, UAW at 1313, citing Chevron U.S.A., Inc. v. NRDC, 
467, U.S. 837, 843 (1984)).
    The Court reviewing the grain dust standard also deferred to OSHA's 
reasonable view that the Agency was not subject to the feasibility 
mandate of section 6(b)(5) in regulating explosive quantities of grain 
dust (National Grain & Feed Association v. OSHA (NGFA II), 866 F.2d 
717, 733 (5th Cir. 1989)). It therefore applied the criteria of section 
3(8), requiring the Agency to establish that the standard is 
``reasonably necessary or appropriate'' to protect section 3(8), 
requiring the Agency to establish that the standard is ``reasonably 
necessary or appropriate'' to protect employee safety.
    As explained in Section I, Background, and Section III, Summary and 
Explanation of the Standard, above, and in Section VI, Summary of the 
Final Regulatory Impact Analysis and Regulatory Flexibility Analysis, 
below, OSHA has determined that the failure to protect employees from 
fall hazards poses significant risks to employees and that the 
provisions of the final rule are reasonably necessary to protect 
affected employees from those risks. The Agency estimates that 
compliance with the revised fall protection standard will cost $70 
million annually and will reduce the risk of the identified hazards 
(preventing 79 fatalities and 56,400 injuries annually). This 
constitutes a substantial reduction of significant risk of material 
harm for the exposed population of approximately 4 million construction 
employees. The Agency believes that compliance is technologically 
feasible because the rulemaking record indicates that the measures 
required by the standard are already in general use throughout the 
construction industry.
    Additionally, OSHA believes that compliance is economically 
feasible as documented in the Regulatory Impact Analysis.
    As detailed in Table 1, below, the standard's costs, benefits, and 
compliance requirements are consistent with those of other OSHA safety 
standards, such as the Hazardous Waste Operations and Emergency 
Response (HAZWOPER) standard.

     OSHA assessed employee risk by evaluating exposure to fall hazards 
throughout the construction industry, except insofar as 
Sec. 1926.500(a)(2) specified construction activity that is not covered 
by subpart M. The Summary of the Final Regulatory Impact Analysis and 
Regulatory Flexibility Analysis, Section IV, above, presents OSHA's 
estimate of the costs and benefits of the revised fall protection 
standard in terms of the Standard Industrial Classification (SIC) codes 
for the industries regulated.
     The record indicates clearly that employees in all covered sectors 
face significant risks related to fall hazards, and that compliance 
with the revised fall protection standard is reasonably necessary to 
protect affected employees from that risk.
    OSHA has considered and responded to all substantive comments 
regarding the proposed fall protection standard on their merits in the 
Section III, Summary and Explanation of the Standard, earlier in this 
preamble. In particular, OSHA evaluated all suggested changes to the 
proposed rule in terms of their impact on worker safety, their 
feasibility, their cost effectiveness, and their consonance with the 
OSH Act.

VII. State Plan Requirements

     The 25 States and territories with their own OSHA-approved 
occupational safety and health plans must revise their existing 
standards within 6 months of the publication date of the final standard 
or show OSHA why there is no need for action, e.g., because an existing 
State standard covering this area is already ``at least as effective'' 
as the revised Federal standard. These States and territories are: 
Alaska, Arizona, California, Connecticut, (State and local government 
workers only), Hawaii, Indiana, Iowa, Kentucky, Maryland, Michigan, 
Minnesota, Nevada, New Mexico, New York, (State and local government 
workers only), North Carolina, Oregon, Puerto Rico, South Carolina, 
Tennessee, Utah, Vermont, Virginia, Virgin Islands, Washington and 
Wyoming.

VIII. Federalism

     The Final Rule has been reviewed in accordance with Executive 
Order 12612 (52 FR 41685; October 30, 1987) regarding Federalism. This 
Order requires that agencies, to the extent possible, refrain from 
limiting state policy options, consult with states prior to taking any 
actions that would restrict state policy options, and take such actions 
only when there is clear constitutional authority and the presence of a 
problem of national scope. The Order provides for preemption of state 
law only if there is a clear Congressional intent for the agency to do 
so. Any such preemption is to be limited to the extent possible.
    Section 18 of the Occupational Safety and Health Act (OSH Act), 
expresses Congress' clear intent to preempt state laws relating to 
issues with respect to which Federal OSHA has promulgated occupational 
safety or health standards. Under the OSH Act a state can avoid 
preemption only if it submits, and obtains Federal approval of, a plan 
for the development of such standards and their enforcement. 
Occupational safety and health standards developed by such Plan-States 
must, among other things, be at least as effective in providing safe 
and healthful employment and places of employment as the Federal 
standards. Where such standards are applicable to products distributed 
or used in interstate commerce, they may not unduly burden commerce, 
must be justified by compelling local conditions, see Section 18(c)(2).
    The Federal fall protection standards for construction workers are 
not unique to any one state or region of the country. Nonetheless, 
states with occupational safety and health plans approved under Section 
18 of the OSH Act will be able to develop their own state standards to 
deal with any special problems which might be encountered in a 
particular area. Moreover, because this standard is written in general, 
performance-oriented terms, there is considerable flexibility for State 
plans to require, and for affected employers to use, methods of 
compliance which are appropriate to the working conditions covered by 
the standard.
    In brief, this Final Rule addresses a clear national problem 
related to occupational safety and health of construction workers. 
Those states which have elected to participate under Section 18 of the 
OSH Act are not preempted by this standard, and will be able to address 
special conditions within the framework of the Federal Act while 
ensuring that the state standards are at least as effective as that 
standard.

IX. OMB Review Under the Paperwork Reduction Act

    The OMB regulations, 5 CFR part 1320, contain procedures for 
agencies to follow in obtaining OMB clearance for information 
collection requirements under the Paperwork Reduction Act, 44 U.S.C. 
3501 et seq. The final Fall Protection standard requires employers who 
use fall protection plans to allow OSHA access to those plans to 
determine if they are in compliance with Sec. 1926.502(k). The 
collection of information has been approved and the OMB clearance 
number is 1218-0197.

    (b) Definitions.
    Anchorage means a secure point of attachment for lifelines, 
lanyards or deceleration devices.
    Body belt (safety belt) means a strap with means both for securing 
it about the waist and for attaching it to a lanyard, lifeline, or 
deceleration device.
    Body harness means straps which may be secured about the employee 
in a manner that will distribute the fall arrest forces over at least 
the thighs, pelvis, waist, chest and shoulders with means for attaching 
it to other components of a personal fall arrest system.
    Buckle means any device for holding the body belt or body harness 
closed around the employee's body.
    Connector means a device which is used to couple (connect) parts of 
the personal fall arrest system and positioning device systems 
together. It may be an independent component of the system, such as a 
carabiner, or it may be an integral component of part of the system 
(such as a buckle or dee-ring sewn into a body belt or body harness, or 
a snap-hook spliced or sewn to a lanyard or self-retracting lanyard).
    Controlled access zone (CAZ) means an area in which certain work 
(e.g., overhand bricklaying) may take place without the use of 
guardrail systems, personal fall arrest systems, or safety net systems 
and access to the zone is controlled.
    Dangerous equipment means equipment (such as pickling or 
galvanizing tanks, degreasing units, machinery, electrical equipment, 
and other units) which, as a result of form or function, may be 
hazardous to employees who fall onto or into such equipment.
    Deceleration device means any mechanism, such as a rope grab, rip-
stitch lanyard, specially-woven lanyard, tearing or deforming lanyards, 
automatic self-retracting lifelines/lanyards, etc., which serves to 
dissipate a substantial amount of energy during a fall arrest, or 
otherwise limit the energy imposed on an employee during fall arrest.
    Deceleration distance means the additional vertical distance a 
falling employee travels, excluding lifeline elongation and free fall 
distance, before stopping, from the point at which the deceleration 
device begins to operate. It is measured as the distance between the 
location of an employee's body belt or body harness attachment point at 
the moment of activation (at the onset of fall arrest forces) of the 
deceleration device during a fall, and the location of that attachment 
point after the employee comes to a full stop.
    Equivalent means alternative designs, materials, or methods to 
protect against a hazard which the employer can demonstrate will 
provide an equal or greater degree of safety for employees than the 
methods, materials or designs specified in the standard.
    Failure means load refusal, breakage, or separation of component 
parts. Load refusal is the point where the ultimate strength is 
exceeded.
    Free fall means the act of falling before a personal fall arrest 
system begins to apply force to arrest the fall.
    Free fall distance means the vertical displacement of the fall 
arrest attachment point on the employee's body belt or body harness 
between onset of the fall and just before the system begins to apply 
force to arrest the fall. This distance excludes deceleration distance, 
and lifeline/lanyard elongation, but includes any deceleration device 
slide distance or self-retracting lifeline/lanyard extension before 
they operate and fall arrest forces occur.
    Guardrail system means a barrier erected to prevent employees from 
falling to lower levels.
    Hole means a gap or void 2 inches (5.1 cm) or more in its least 
dimension, in a floor, roof, or other walking/working surface.
    Infeasible means that it is impossible to perform the construction 
work using a conventional fall protection system (i.e., guardrail 
system, safety net system, or personal fall arrest system) or that it 
is technologically impossible to use any one of these systems to 
provide fall protection.
    Lanyard means a flexible line of rope, wire rope, or strap which 
generally has a connector at each end for connecting the body belt or 
body harness to a deceleration device, lifeline, or anchorage.
    Leading edge means the edge of a floor, roof, or formwork for a 
floor or other walking/working surface (such as the deck) which changes 
location as additional floor, roof, decking, or formwork sections are 
placed, formed, or constructed. A leading edge is considered to be an 
``unprotected side and edge'' during periods when it is not actively 
and continuously under construction.
    Lifeline means a component consisting of a flexible line for 
connection to an anchorage at one end to hang vertically (vertical 
lifeline), or for connection to anchorages at both ends to stretch 
horizontally (horizontal lifeline), and which serves as a means for 
connecting other components of a personal fall arrest system to the 
anchorage.
    Low-slope roof means a roof having a slope less than or equal to 4 
in 12 (vertical to horizontal).
    Lower levels means those areas or surfaces to which an employee can 
fall. Such areas or surfaces include, but are not limited to, ground 
levels, floors, platforms, ramps, runways, excavations, pits, tanks, 
material, water, equipment, structures, or portions thereof.
    Mechanical equipment means all motor or human propelled wheeled 
equipment used for roofing work, except wheelbarrows and mopcarts.
    Opening means a gap or void 30 inches (76 cm) or more high and 18 
inches (48 cm) or more wide, in a wall or partition, through which 
employees can fall to a lower level.
    Overhand bricklaying and related work means the process of laying 
bricks and masonry units such that the surface of the wall to be 
jointed is on the opposite side of the wall from the mason, requiring 
the mason to lean over the wall to complete the work. Related work 
includes mason tending and electrical installation incorporated into 
the brick wall during the overhand bricklaying process.
    Personal fall arrest system means a system used to arrest an 
employee in a fall from a working level. It consists of an anchorage, 
connectors, a body belt or body harness and may include a lanyard, 
deceleration device, lifeline, or suitable combinations of these. As of 
January 1, 1998, the use of a body belt for fall arrest is prohibited.
    Positioning device system means a body belt or body harness system 
rigged to allow an employee to be supported on an elevated vertical 
surface, such as a wall, and work with both hands free while leaning.
    Rope grab means a deceleration device which travels on a lifeline 
and automatically, by friction, engages the lifeline and locks so as to 
arrest the fall of an employee. A rope grab usually employs the 
principle of inertial locking, cam/level locking, or both.
    Roof means the exterior surface on the top of a building. This does 
not include floors or formwork which, because a building has not been 
completed, temporarily become the top surface of a building.
    Roofing work means the hoisting, storage, application, and removal 
of roofing materials and equipment, including related insulation, sheet 
metal, and vapor barrier work, but not including the construction of 
the roof deck.
    Safety-monitoring system means a safety system in which a competent 
person is responsible for recognizing and warning employees of fall 
hazards.
    Self-retracting lifeline/lanyard means a deceleration device 
containing a drum-wound line which can be slowly extracted from, or 
retracted onto, the drum under slight tension during normal employee 
movement, and which, after onset of a fall, automatically locks the 
drum and arrests the fall.
    Snaphook means a connector comprised of a hook-shaped member with a 
normally closed keeper, or similar arrangement, which may be opened to 
permit the hook to receive an object and, when released, automatically 
closes to retain the object. Snaphooks are generally one of two types:
    (1) The locking type with a self-closing, self-locking keeper which 
remains closed and locked until unlocked and pressed open for 
connection or disconnection; or
    (2) The non-locking type with a self-closing keeper which remains 
closed until pressed open for connection or disconnection. As of 
January 1, 1998, the use of a non-locking snaphook as part of personal 
fall arrest systems and positioning device systems is prohibited.
    Steep roof means a roof having a slope greater than 4 in 12 
(vertical to horizontal).
    Toeboard means a low protective barrier that will prevent the fall 
of materials and equipment to lower levels and provide protection from 
falls for personnel.
    Unprotected sides and edges means any side or edge (except at 
entrances to points of access) of a walking/working surface, e.g., 
floor, roof, ramp, or runway where there is no wall or guardrail system 
at least 39 inches (1.0 m) high.
    Walking/working surface means any surface, whether horizontal or 
vertical on which an employee walks or works, including, but not 
limited to, floors, roofs, ramps, bridges, runways, formwork and 
concrete reinforcing steel but not including ladders, vehicles, or 
trailers, on which employees must be located in order to perform their 
job duties.
    Warning line system means a barrier erected on a roof to warn 
employees that they are approaching an unprotected roof side or edge, 
and which designates an area in which roofing work may take place 
without the use of guardrail, body belt, or safety net systems to 
protect employees in the area.
    Work area means that portion of a walking/working surface where job 
duties are being performed.


Sec. 1926.501  Duty to have fall protection.

    (a) General. (1) This section sets forth requirements for employers 
to provide fall protection systems. All fall protection required by 
this section shall conform to the criteria set forth in Sec. 1926.502 
of this subpart.
    (2) The employer shall determine if the walking/working surfaces on 
which its employees are to work have the strength and structural 
integrity to support employees safely. Employees shall be allowed to 
work on those surfaces only when the surfaces have the requisite 
strength and structural integrity.
    (b)(1) Unprotected sides and edges. Each employee on a walking/
working surface (horizontal and vertical surface) with an unprotected 
side or edge which is 6 feet (1.8 m) or more above a lower level shall 
be protected from falling by the use of guardrail systems, safety net 
systems, or personal fall arrest systems.
    (2) Leading edges. (i) Each employee who is constructing a leading 
edge 6 feet (1.8 m) or more above lower levels shall be protected from 
falling by guardrail systems, safety net systems, or personal fall 
arrest systems. Exception: When the employer can demonstrate that it is 
infeasible or creates a greater hazard to use these systems, the 
employer shall develop and implement a fall protection plan which meets 
the requirements of paragraph (k) of Sec. 1926.502.

    Note: There is a presumption that it is feasible and will not 
create a greater hazard to implement at least one of the above-
listed fall protection systems. Accordingly, the employer has the 
burden of establishing that it is appropriate to implement a fall 
protection plan which complies with Sec. 1926.502(k) for a 
particular workplace situation, in lieu of implementing any of those 
systems.

    (ii) Each employee on a walking/working surface 6 feet (1.8 m) or 
more above a lower level where leading edges are under construction, 
but who is not engaged in the leading edge work, shall be protected 
from falling by a guardrail system, safety net system, or personal fall 
arrest system. If a guardrail system is chosen to provide the fall 
protection, and a controlled access zone has already been established 
for leading edge work, the control line may be used in lieu of a 
guardrail along the edge that parallels the leading edge.
    (3) Hoist areas. Each employee in a hoist area shall be protected 
from falling 6 feet (1.8 m) or more to lower levels by guardrail 
systems or personal fall arrest systems. If guardrail systems, [or 
chain, gate, or guardrail] or portions thereof, are removed to 
facilitate the hoisting operation (e.g., during landing of materials), 
and an employee must lean through the access opening or out over the 
edge of the access opening (to receive or guide equipment and 
materials, for example), that employee shall be protected from fall 
hazards by a personal fall arrest system.
    (4) Holes. (i) Each employee on walking/working surfaces shall be 
protected from falling through holes (including skylights) more than 6 
feet (1.8 m) above lower levels, by personal fall arrest systems, 
covers, or guardrail systems erected around such holes.
    (ii) Each employee on a walking/working surface shall be protected 
from tripping in or stepping into or through holes (including 
skylights) by covers.
    (iii) Each employee on a walking/working surface shall be protected 
from objects falling through holes (including skylights) by covers.
    (5) Formwork and reinforcing steel. Each employee on the face of 
formwork or reinforcing steel shall be protected from falling 6 feet 
(1.8 m) or more to lower levels by personal fall arrest systems, safety 
net systems, or positioning device systems.
    (6) Ramps, runways, and other walkways. Each employee on ramps, 
runways, and other walkways shall be protected from falling 6 feet (1.8 
m) or more to lower levels by guardrail systems.
    (7) Excavations. (i) Each employee at the edge of an excavation 6 
feet (1.8 m) or more in depth shall be protected from falling by 
guardrail systems, fences, or barricades when the excavations are not 
readily seen because of plant growth or other visual barrier;
    (ii) Each employee at the edge of a well, pit, shaft, and similar 
excavation 6 feet (1.8 m) or more in depth shall be protected from 
falling by guardrail systems, fences, barricades, or covers.
    (8) Dangerous equipment. (i) Each employee less than 6 feet (1.8 m) 
above dangerous equipment shall be protected from falling into or onto 
the dangerous equipment by guardrail systems or by equipment guards.
    (ii) Each employee 6 feet (1.8 m) or more above dangerous equipment 
shall be protected from fall hazards by guardrail systems, personal 
fall arrest systems, or safety net systems.
    (9) Overhand bricklaying and related work. (i) Except as otherwise 
provided in paragraph (b) of this section, each employee performing 
overhand bricklaying and related work 6 feet (1.8 m) or more above 
lower levels, shall be protected from falling by guardrail systems, 
safety net systems, personal fall arrest systems, or shall work in a 
controlled access zone.
    (ii) Each employee reaching more than 10 inches (25 cm) below the 
level of the walking/working surface on which they are working, shall 
be protected from falling by a guardrail system, safety net system, or 
personal fall arrest system.

    Note: Bricklaying operations performed on scaffolds are 
regulated by subpart L--Scaffolds of this part.

    (10) Roofing work on Low-slope roofs. Except as otherwise provided 
in paragraph (b) of this section, each employee engaged in roofing 
activities on low-slope roofs, with unprotected sides and edges 6 feet 
(1.8 m) or more above lower levels shall be protected from falling by 
guardrail systems, safety net systems, personal fall arrest systems, or 
a combination of warning line system and guardrail system, warning line 
system and safety net system, or warning line system and personal fall 
arrest system, or warning line system and safety monitoring system. Or, 
on roofs 50-feet (15.25 m) or less in width (see Appendix A to subpart 
M of this part), the use of a safety monitoring system alone [i.e. 
without the warning line system] is permitted.
    (11) Steep roofs. Each employee on a steep roof with unprotected 
sides and edges 6 feet (1.8 m) or more above lower levels shall be 
protected from falling by guardrail systems with toeboards, safety net 
systems, or personal fall arrest systems.
    (12) Precast concrete erection. Each employee engaged in the 
erection of precast concrete members (including, but not limited to the 
erection of wall panels, columns, beams, and floor and roof ``tees'') 
and related operations such as grouting of precast concrete members, 
who is 6 feet (1.8 m) or more above lower levels shall be protected 
from falling by guardrail systems, safety net systems, or personal fall 
arrest systems, unless another provision in paragraph (b) of this 
section provides for an alternative fall protection measure. Exception: 
When the employer can demonstrate that it is infeasible or creates a 
greater hazard to use these systems, the employer shall develop and 
implement a fall protection plan which meets the requirements of 
paragraph (k) of Sec. 1926.502.

    Note: There is a presumption that it is feasible and will not 
create a greater hazard to implement at least one of the above-
listed fall protection systems. Accordingly, the employer has the 
burden of establishing that it is appropriate to implement a fall 
protection plan which complies with Sec. 1926.502(k) for a 
particular workplace situation, in lieu of implementing any of those 
systems.

    (13) Residential construction. Each employee engaged in residential 
construction activities 6 feet (1.8 m) or more above lower levels shall 
be protected by guardrail systems, safety net system, or personal fall 
arrest system unless another provision in paragraph (b) of this section 
provides for an alternative fall protection measure. Exception: When 
the employer can demonstrate that it is infeasible or creates a greater 
hazard to use these systems, the employer shall develop and implement a 
fall protection plan which meets the requirements of paragraph (k) of 
Sec. 1926.502.

    Note: There is a presumption that it is feasible and will not 
create a greater hazard to implement at least one of the above-
listed fall protection systems. Accordingly, the employer has the 
burden of establishing that it is appropriate to implement a fall 
protection plan which complies with Sec. 1926.502(k) for a 
particular workplace situation, in lieu of implementing any of those 
systems.

    (14) Wall openings. Each employee working on, at, above, or near 
wall openings (including those with chutes attached) where the outside 
bottom edge of the wall opening is 6 feet (1.8 m) or more above lower 
levels and the inside bottom edge of the wall opening is less than 39 
inches (1.0 m) above the walking/working surface, shall be protected 
from falling by the use of a guardrail system, a safety net system, or 
a personal fall arrest system.
    (15) Walking/working surfaces not otherwise addressed. Except as 
provided in Sec. 1926.500(a)(2) or in Sec. 1926.501 (b)(1) through 
(b)(14), each employee on a walking/working surface 6 feet (1.8 m) or 
more above lower levels shall be protected from falling by a guardrail 
system, safety net system, or personal fall arrest system.
    (c) Protection from falling objects. When an employee is exposed to 
falling objects, the employer shall have each employee wear a hard hat 
and shall implement one of the following measures:
    (1) Erect toeboards, screens, or guardrail systems to prevent 
objects from falling from higher levels; or,
    (2) Erect a canopy structure and keep potential fall objects far 
enough from the edge of the higher level so that those objects would 
not go over the edge if they were accidentally displaced; or,
    (3) Barricade the area to which objects could fall, prohibit 
employees from entering the barricaded area, and keep objects that may 
fall far enough away from the edge of a higher level so that those 
objects would not go over the edge if they were accidentally displaced.


Sec. 1926.502  Fall protection systems criteria and practices.

    (a) General. (1) Fall protection systems required by this part 
shall comply with the applicable provisions of this section.
    (2) Employers shall provide and install all fall protection systems

with the following provisions:
    (1) Top edge height of top rails, or equivalent guardrail system 
members, shall be 42 inches (1.1 m) plus or minus 3 inches (8 cm) above 
the walking/working level. When conditions warrant, the height of the 
top edge may exceed the 45-inch height, provided the guardrail system 
meets all other criteria of this paragraph ( ).

    Note: When employees are using stilts, the top edge height of 
the top rail, or equivalent member, shall be increased an amount 
equal to the height of the stilts.

    (2) Midrails, screens, mesh, intermediate vertical members, or 
equivalent intermediate structural members shall be installed between 
the top edge of the guardrail system and the walking/working surface 
when there is no wall or parapet wall at least 21 inches (53 cm) high.

point along the top edge.
    (4) When the 200 pound (890 N) test load specified in paragraph 
(b)(3) of this section is applied in a downward direction, the top edge 
of the guardrail shall not deflect to a height less than 39 inches (1.0 
m) above the walking/working level. Guardrail system components 
selected and constructed in accordance with the Appendix B to subpart M 
of this part will be deemed to meet this requirement.
    (5) Midrails, screens, mesh, intermediate vertical members, solid 
panels, and equivalent structural members shall be capable of 
withstanding, without failure, a force of at least 150 pounds (666 N) 
applied in any downward or outward direction at any point along the 
midrail or other member.
    (6) Guardrail systems shall be so surfaced as to prevent injury to 
an employee from punctures or lacerations, and to prevent snagging of 
clothing.
    (7) The ends of all top rails and midrails shall not overhang the 
terminal posts, except where such overhang does not constitute a 
projection hazard.
    (8) Steel banding and plastic banding shall not be used as top 
rails or midrails.
    (9) Top rails and midrails shall be at least one-quarter inch (0.6 
cm) nominal diameter or thickness to prevent cuts and lacerations. If

6-foot intervals with high-visibility material.
    (10) When guardrail systems are used at hoisting areas, a chain, 
gate or removable guardrail section shall be placed across the access 
opening between guardrail sections when hoisting operations are not 
taking place.
    (11) When guardrail systems are used at holes, they shall be 
erected on all unprotected sides or edges of the hole.
    (12) When guardrail systems are used around holes used for the 
passage of materials, the hole shall have not more than two sides 
provided with removable guardrail sections to allow the passage of 
materials. When the hole is not in use, it shall be closed over with a 
cover, or a guardrail system shall be provided along all unprotected 
sides or edges.
    (13) When guardrail systems are used around holes which are used as 
points of access (such as ladderways), they shall be provided with a 
gate, or be so offset that a person cannot walk directly into the hole.
    (14) Guardrail systems used on ramps and runways shall be erected 
along each unprotected side or edge.
    (15) Manila, plastic or synthetic rope being used for top rails or 
midrails shall be inspected as frequently as necessary to ensure that

this section.
    (c) Safety net systems. Safety net systems and their use shall 
comply with the following provisions:
    (1) Safety nets shall be installed as close as practicable under 
the walking/working surface on which employees are working, but in no 
case more than 30 feet (9.1 m) below such level. When nets are used on 
bridges, the potential fall area from the walking/working surface to 
the net shall be unobstructed.
    (2) Safety nets shall extend outward from the outermost projection 
of the work surface as follows: 

------------------------------------------------------------------------
                                         Minimum required horizontal    
   Vertical distance from working     distance of outer edge of net from
  level to horizontal plane of net     the edge of the working surface  
------------------------------------------------------------------------
Up to 5 feet.......................  8 feet.

More than 10 feet..................  13 feet.                           
------------------------------------------------------------------------

    (3) Safety nets shall be installed with sufficient clearance under 
them to prevent contact with the surface or structures below when 
subjected to an impact force equal to the drop test specified in 
paragraph (c)(4) of this section.
    (4) Safety nets and their installations shall be capable of 
absorbing an impact force equal to that produced by the drop test 
specified in paragraph (c)(4)(i) of this section.
    (i) Except as provided in paragraph (c)(4)(ii) of this section, 
safety nets and safety net installations shall be drop-tested at the 
jobsite after initial installation and before being used as a fall 
protection system, whenever relocated, after major repair, and at 6-
month intervals if left in one place. The drop-test shall consist of a 
400 pound (180 kg) bag of sand 30  2 inches (76 
 5 cm) in diameter dropped into the net from the highest 
walking/working surface at which employees are exposed to fall hazards, 
but not from less than 42 inches (1.1 m) above that level.
    (ii) When the employer can demonstrate that it is unreasonable to 
perform the drop-test required by paragraph (c)(4)(i) of this section, 
the employer (or a designated competent person) shall certify that the 
net and net installation is in compliance with the provisions of 
paragraphs (c)(3) and (c)(4)(i) of this section by preparing a 
certification record prior to the net being used as a fall protection 
system. The certification record must include an identification of the 
net and net installation for which the certification record is being 
prepared; the date that it was determined that the identified net and

employees engaged in leading edge work, precast concrete erection work, 
or residential construction work (See Sec. 1926.501(b)(2), (b)(12), and 
(b)(13)) who can demonstrate that it is infeasible or it creates a 
greater hazard to use conventional fall protection equipment. The fall 
protection plan must conform to the following provisions.
    (1) The fall protection plan shall be prepared by a qualified 
person and developed specifically for the site where the leading edge 
work, precast concrete work, or residential construction work is being

the supervision of a competent person.
    (5) The fall protection plan shall document the reasons why the use 
of conventional fall protection systems (guardrail systems, personal 
fall arrest systems, or safety nets systems) are infeasible or why 
their use would create a greater hazard.
    (6) The fall protection plan shall include a written discussion of 
other measures that will be taken to reduce or eliminate the fall 
hazard for workers who cannot be provided with protection from the 
conventional fall protection systems. For example, the employer shall 
discuss the extent to which scaffolds, ladders, or vehicle mounted work 
platforms can be used to provide a safer working surface and thereby 
reduce the hazard of falling.
    (7) The fall protection plan shall identify each location where 
conventional fall protection methods cannot be used. These locations 
shall then be classified as controlled access zones and the employer 
must comply with the criteria in paragraph (g) of this section.

employer shall implement a safety monitoring system in conformance with 
Sec. 1926.502(h).
    (9) The fall protection plan must include a statement which 
provides the name or other method of identification for each employee 
who is designated to work in controlled access zones. No other 
employees may enter controlled access zones.
    (10) In the event an employee falls, or some other related, serious 
incident occurs, (e.g., a near miss) the employer shall investigate the 
circumstances of the fall or other incident to determine if the fall 
protection plan needs to be changed (e.g. new practices, procedures, or 
training) and shall implement those changes to prevent similar types of 
falls or incidents.


Sec. 1926.503  Training requirements.

    The following training provisions supplement and clarify the 
requirements of Sec. 1926.21 regarding the hazards addressed in subpart 
M of this part.
    (a) Training Program. (1) The employer shall provide a training 
program for each employee who might be exposed to fall hazards. The 
program shall enable each employee to recognize the hazards of falling 
and shall train each employee in the procedures to be followed in order 
to minimize these hazards.
    (2) The employer shall assure that each employee has been trained, 
as necessary, by a competent person qualified in the following areas:
    (i) The nature of fall hazards in the work area;
    (ii) The correct procedures for erecting, maintaining, 
disassembling, and inspecting the fall protection systems to be used;
    (iii) The use and operation of guardrail systems, personal fall 
arrest systems, safety net systems, warning line systems, safety 
monitoring systems, controlled access zones, and other protection to be 
used;
    (iv) The role of each employee in the safety monitoring system when 
this system is used;
    (v) The limitations on the use of mechanical equipment during the 
performance of roofing work on low-sloped roofs;
    (vi) The correct procedures for the handling and storage of 
equipment and materials and the erection of overhead protection; and
    (vii) The role of employees in fall protection plans;
    (viii) The standards contained in this subpart.
    (b) Certification of training. (1) The employer shall verify 
compliance with paragraph (a) of this section by preparing a written 
certification record. The written certification record shall contain 
the name or other identity of the employee trained, the date(s) of the 
training, and the signature of the person who conducted the training or 
the signature of the employer. If the employer relies on training 
conducted by another employer or completed prior to the effective date 
of this section, the certification record shall indicate the date the 
employer determined the prior training was adequate rather than the 
date of actual training.
    (2) The latest training certification shall be maintained.
    (c) Retraining. When the employer has reason to believe that any 
affected employee who has already been trained does not have the 
understanding and skill required by paragraph (a) of this section, the 
employer shall retrain each such employee. Circumstances where 
retraining is required include, but are not limited to, situations 
where:
    (1) Changes in the workplace render previous training obsolete; or
    (2) Changes in the types of fall protection systems or equipment to 
be used render previous training obsolete; or
    (3) Inadequacies in an affected employee's knowledge or use of fall 
protection systems or equipment indicate that the employee has not 
retained the requisite understanding or skill.

    Note: The following appendices to subpart M of this part serve 
as non-mandatory guidelines to assist employers in complying with 
the appropriate requirements of subpart M of this part.

Appendix A to Subpart M--Determining Roof Widths Non-mandatory 
Guidelines for Complying With Sec. 1926.501(b)(10)

    (1) This Appendix serves as a guideline to assist employers 
complying with the requirements of Sec. 1926.501(b)(10). Section 
1910.501(b)(10) allows the use of a safety monitoring system alone 
as a means of providing fall protection during the performance of 
roofing operations on low-sloped roofs 50 feet (15.25 m) or less in 
width. Each example in the appendix shows a roof plan or plans and 
indicates where each roof or roof area is to be measured to 
determine its width. Section views or elevation views are shown 
where appropriate. Some examples show ``correct'' and ``incorrect'' 
subdivisions of irregularly shaped roofs divided into smaller, 
regularly shaped areas. In all examples, the dimension selected to 
be the width of an area is the lesser of the two primary dimensions 
of the area, as viewed from above. Example A shows that on a simple 
rectangular roof, width is the lesser of the two primary overall 
dimensions. This is also the case with roofs which are sloped toward 
or away from the roof center, as shown in Example B.
    (2) Many roofs are not simple rectangles. Such roofs may be 
broken down into subareas as shown in Example C. The process of 
dividing a roof area can produce many different configurations. 
Example C gives the general rule of using dividing lines of minimum 
length to minimize the size and number of the areas which are 
potentially less than 50 feet (15.25 m) wide. The intent is to 
minimize the number of roof areas where safety monitoring systems 
alone are sufficient protection.
    (3) Roofs which are comprised of several separate, non-
contiguous roof areas, as in Example D, may be considered as a 
series of individual roofs. Some roofs have penthouses, additional 
floors, courtyard openings, or similar architectural features; 
Example E shows how the rule for dividing roofs into subareas is 
applied to such configurations. Irregular, non-rectangular roofs 
must be considered on an individual basis, as shown in Example F.

Example B

Sloped Rectangular Shaped Roofs

TR09AU94.001


BILLING CODE 4510-26-C

Example C

Irregularly Shaped Roofs With Rectangular Shaped Sections

    Such roofs are to be divided into sub-areas by using dividing 
lines of minimum length to minimize the size and number of the areas 
which are potentially less than or equal to 50 feet (15.25 meters) 
in width, in order to limit the size of roof areas where the safety 
monitoring system alone can be used [1926.502(b)(10)]. Dotted lines 
are used in the examples to show the location of dividing lines. W

Appendix B to Subpart M--Guardrail Systems Non-Mandatory Guidelines 
for Complying with Sec. 1926.502(b)

    The standard requires guardrail systems and components to be 
designed and built to meet the requirements of Sec. 1926.502 (b) 
(3), (4), and (5). This Appendix serves as a non-mandatory guideline 
to assist employers in complying with these requirements. An 
employer may use these guidelines as a starting point for designing 
guardrail systems. However, the guidelines do not provide all the 
information necessary to build a complete system, and the employer 
is still responsible for designing and assembling these components 
in such a way that the completed system will meet the requirements 
of Sec. 1926.502(b) (3), (4), and (5). Components for which no 
specific guidelines are given in this Appendix (e.g., joints, base 
connections, components made with other materials, and components 
with other dimensions) must also be designed and constructed in such 
a way that the completed system meets the requirements of 
Sec. 1926.502.
    (1) For wood railings: Wood components shall be minimum 1500 lb-
ft/in2 fiber (stress grade) construction grade lumber; the 
posts shall be at least 2-inch by 4-inch (5 cm x 10 cm) lumber 
spaced not more than 8 feet (2.4 m) apart on centers; the top rail 
shall be at least 2-inch by 4-inch (5 cm x 10 cm) lumber, the 
intermediate rail shall be at least 1-inch by 6-inch (2.5 cm x 15 
cm) lumber. All lumber dimensions are nominal sizes as provided by 
the American Softwood Lumber Standards, dated January 1970.
    (2) For pipe railings: posts, top rails, and intermediate 
railings shall be at least one and one-half inches nominal diameter 
(schedule 40 pipe) with posts spaced not more than 8 feet (2.4 m) 
apart on centers.
    (3) For structural steel railings: posts, top rails, and 
intermediate rails shall be at least 2-inch by 2-inch (5 cm x 10 cm) 
by \3/8\-inch (1.1 cm) angles, with posts spaced not more than 8 
feet (2.4 m) apart on centers.

Appendix C to Subpart M--Personal Fall Arrest Systems Non-Mandatory 
Guidelines for Complying With Sec. 1926.502(d)

    I. Test methods for personal fall arrest systems and positioning 
device systems--(a) General. This appendix serves as a non-mandatory 
guideline to assist employers comply with the requirements in 
Sec. 1926.502(d). Paragraphs (b), (c), (d) and (e) of this Appendix 
describe test procedures which may be used to determine compliance 
with the requirements in Sec. 1926.502 (d)(16). As noted in Appendix 
D of this subpart, the test methods listed here in Appendix C can 
also be used to assist employers comply with the requirements in 
Sec. 1926.502(e) (3) and (4) for positioning device systems.
    (b) General conditions for all tests in the Appendix to 
Sec. 1926.502(d). (1) Lifelines, lanyards and deceleration devices 
should be attached to an anchorage and connected to the body-belt or 
body harness in the same manner as they would be when used to 
protect employees.
    (2) The anchorage should be rigid, and should not have a 
deflection greater than 0.04 inches (1 mm) when a force of 2,250 
pounds (10 kN) is applied.
    (3) The frequency response of the load measuring instrumentation 
should be 500 Hz.
    (4) The test weight used in the strength and force tests should 
be a rigid, metal, cylindrical or torso-shaped object with a girth 
of 38 inches plus or minus 4 inches (96 cm plus or minus 10 cm).
    (5) The lanyard or lifeline used to create the free fall 
distance should be supplied with the system, or in its absence, the 
least elastic lanyard or lifeline available to be used with the 
system.
    (6) The test weight for each test should be hoisted to the 
required level and should be quickly released without having any 
appreciable motion imparted to it.
    (7) The system's performance should be evaluated taking into 
account the range of environmental conditions for which it is 
designed to be used.
    (8) Following the test, the system need not be capable of 
further operation.
    (c) Strength test. (1) During the testing of all systems, a test 
weight of 300 pounds plus or minus 5 pounds (135 kg plus or minus 
2.5 kg) should be used. (See paragraph (b)(4) of this section.)
    (2) The test consists of dropping the test weight once. A new 
unused system should be used for each test.
    (3) For lanyard systems, the lanyard length should be 6 feet 
plus or minus 2 inches (1.83 m plus or minus 5 cm) as measured from 
the fixed anchorage to the attachment on the body belt or body 
harness.
    (4) For rope-grab-type deceleration systems, the length of the 
lifeline above the centerline of the grabbing mechanism to the 
lifeline's anchorage point should not exceed 2 feet (0.61 m).
    (5) For lanyard systems, for systems with deceleration devices 
which do not automatically limit free fall distance to 2 feet (0.61 
m ) or less, and for systems with deceleration devices which have a 
connection distance in excess of 1 foot (0.3 m) (measured between 
the centerline of the lifeline and the attachment point to the body 
belt or harness), the test weight should be rigged to free fall a 
distance of 7.5 feet (2.3 m) from a point that is 1.5 feet (.46 m) 
above the anchorage point, to its hanging location (6 feet below the 
anchorage). The test weight should fall without interference, 
obstruction, or hitting the floor or ground during the test. In some 
cases a non-elastic wire lanyard of sufficient length may need to be 
added to the system (for test purposes) to create the necessary free 
fall distance.
    (6) For deceleration device systems with integral lifelines or 
lanyards which automatically limit free fall distance to 2 feet 
(0.61 m) or less, the test weight should be rigged to free fall a 
distance of 4 feet (1.22 m).
    (7) Any weight which detaches from the belt or harness has 
failed the strength test.
    (d) Force test--(1) General. The test consists of dropping the 
respective test weight once as specified in paragraph (d)(2)(i) or 
(d)(3)(i) of this section. A new, unused system should be used for 
each test.
    (2) For lanyard systems. (i) A test weight of 220 pounds plus or 
minus 3 pounds (100 kg plus or minus 1.6 kg) should be used. (See 
paragraph (b)(4) of this appendix).
    (ii) Lanyard length should be 6 feet plus or minus two inches 
(1.83 m plus or minus 5 cm) as measured from the fixed anchorage to 
the attachment on the body belt or body harness.
    (iii) The test weight should fall free from the anchorage level 
to its hanging location (a total of 6 feet (1.83 m) free fall 
distance) without interference, obstruction, or hitting the floor or 
ground during the test.
    (3) For all other systems. (i) A test weight of 220 pounds plus 
or minus 3 pounds (100 kg plus or minus 1.6 kg) should be used. (See 
paragraph (b)(4) of this appendix)
    (ii) The free fall distance to be used in the test should be the 
maximum fall distance physically permitted by the system during 
normal use conditions, up to a maximum free fall distance for the 
test weight of 6 feet (1.83 m), except as follows:
    (A) For deceleration systems which have a connection link or 
lanyard, the test weight should free fall a distance equal to the 
connection distance (measured between the centerline of the lifeline 
and the attachment point to the body belt or harness).
    (B) For deceleration device systems with integral lifelines or 
lanyards which automatically limit free fall distance to 2 feet 
(0.61 m) or less, the test weight should free fall a distance equal 
to that permitted by the system in normal use. (For example, to test 
a system with a self-retracting lifeline or lanyard, the test weight 
should be supported and the system allowed to retract the lifeline 
or lanyard as it would in normal use. The test weight would then be 
released and the force and deceleration distance measured).
    (4) A system fails the force test if the recorded maximum 
arresting force exceeds 1,260 pounds (5.6 kN) when using a body 
belt, and/or exceeds 2,520 pounds (11.2 kN) when using a body 
harness.
    (5) The maximum elongation and deceleration distance should be 
recorded during the force test.
    (e) Deceleration device tests. (1) General. The device should be 
evaluated or tested under the environmental conditions, (such as 
rain, ice, grease, dirt, type of lifeline, etc.), for which the 
device is designed.
    (2) Rope-grab-type deceleration devices. (i) Devices should be 
moved on a lifeline 1,000 times over the same length of line a 
distance of not less than 1 foot (30.5 cm), and the mechanism should 
lock each time.
    (ii) Unless the device is permanently marked to indicate the 
type(s) of lifeline which must be used, several types (different 
diameters and different materials), of lifelines should be used to 
test the device.
    (3) Other self-activating-type deceleration devices. The locking 
mechanisms of other self-activating-type deceleration devices 
designed for more than one arrest should lock each of 1,000 times as 
they would in normal service.
    II. Additional non-mandatory guidelines for personal fall arrest 
systems. The following information constitutes additional guidelines 
for use in complying with requirements for a personal fall arrest 
system.
    (a) Selection and use considerations. (1) The kind of personal 
fall arrest system selected should match the particular work 
situation, and any possible free fall distance should be kept to a 
minimum. Consideration should be given to the particular work 
environment. For example, the presence of acids, dirt, moisture, 
oil, grease, etc., and their effect on the system, should be 
evaluated. Hot or cold environments may also have an adverse effect 
on the system. Wire rope should not be used where an electrical 
hazard is anticipated. As required by the standard, the employer 
must plan to have means available to promptly rescue an employee 
should a fall occur, since the suspended employee may not be able to 
reach a work level independently.
    (2) Where lanyards, connectors, and lifelines are subject to 
damage by work operations such as welding, chemical cleaning, and 
sandblasting, the component should be protected, or other securing 
systems should be used. The employer should fully evaluate the work 
conditions and environment (including seasonal weather changes) 
before selecting the appropriate personal fall protection system. 
Once in use, the system's effectiveness should be monitored. In some 
cases, a program for cleaning and maintenance of the system may be 
necessary.
    (b) Testing considerations. Before purchasing or putting into 
use a personal fall arrest system, an employer should obtain from 
the supplier information about the system based on its performance 
during testing so that the employer can know if the system meets 
this standard. Testing should be done using recognized test methods. 
This Appendix contains test methods recognized for evaluating the 
performance of fall arrest systems. Not all systems may need to be 
individually tested; the performance of some systems may be based on 
data and calculations derived from testing of similar systems, 
provided that enough information is available to demonstrate 
similarity of function and design.
    (c) Component compatibility considerations. Ideally, a personal 
fall arrest system is designed, tested, and supplied as a complete 
system. However, it is common practice for lanyards, connectors, 
lifelines, deceleration devices, body belts and body harnesses to be 
interchanged since some components wear out before others. The 
employer and employee should realize that not all components are 
interchangeable. For instance, a lanyard should not be connected 
between a body belt (or harness) and a deceleration device of the 
self-retracting type since this can result in additional free fall 
for which the system was not designed. Any substitution or change to 
a personal fall arrest system should be fully evaluated or tested by 
a competent person to determine that it meets the standard, before 
the modified system is put in use.
    (d) Employee training considerations. Thorough employee training 
in the selection and use of personal fall arrest systems is 
imperative. Employees must be trained in the safe use of the system. 
This should include the following: application limits; proper 
anchoring and tie-off techniques; estimation of free fall distance, 
including determination of deceleration distance, and total fall 
distance to prevent striking a lower level; methods of use; and 
inspection and storage of the system. Careless or improper use of 
the equipment can result in serious injury or death. Employers and 
employees should become familiar with the material in this Appendix, 
as well as manufacturer's recommendations, before a system is used. 
Of uppermost importance is the reduction in strength caused by 
certain tie-offs (such as using knots, tying around sharp edges, 
etc.) and maximum permitted free fall distance. Also, to be stressed 
are the importance of inspections prior to use, the limitations of 
the equipment, and unique conditions at the worksite which may be 
important in determining the type of system to use.
    (e) Instruction considerations. Employers should obtain 
comprehensive instructions from the supplier as to the system's 
proper use and application, including, where applicable:
    (1) The force measured during the sample force test;
    (2) The maximum elongation measured for lanyards during the 
force test;
    (3) The deceleration distance measured for deceleration devices 
during the force test;
    (4) Caution statements on critical use limitations;
    (5) Application limits;
    (6) Proper hook-up, anchoring and tie-off techniques, including 
the proper dee-ring or other attachment point to use on the body 
belt and harness for fall arrest;
    (7) Proper climbing techniques;
    (8) Methods of inspection, use, cleaning, and storage; and
    (9) Specific lifelines which may be used. This information 
should be provided to employees during training.
    (f) Rescue considerations. As required by Sec. 1926.502(d)(20), 
when personal fall arrest systems are used, the employer must assure 
that employees can be promptly rescued or can rescue themselves 
should a fall occur. The availability of rescue personnel, ladders 
or other rescue equipment should be evaluated. In some situations, 
equipment which allows employees to rescue themselves after the fall 
has been arrested may be desirable, such as devices which have 
descent capability.
    (g) Inspection considerations. As required by 
Sec. 1926.502(d)(21), personal fall arrest systems must be regularly 
inspected. Any component with any significant defect, such as cuts, 
tears, abrasions, mold, or undue stretching; alterations or 
additions which might affect its efficiency; damage due to 
deterioration; contact with fire, acids, or other corrosives; 
distorted hooks or faulty hook springs; tongues unfitted to the 
shoulder of buckles; loose or damaged mountings; non-functioning 
parts; or wearing or internal deterioration in the ropes must be 
withdrawn from service immediately, and should be tagged or marked 
as unusable, or destroyed.
    (h) Tie-off considerations. (1) One of the most important 
aspects of personal fall protection systems is fully planning the 
system before it is put into use. Probably the most overlooked 
component is planning for suitable anchorage points. Such planning 
should ideally be done before the structure or building is 
constructed so that anchorage points can be incorporated during 
construction for use later for window cleaning or other building 
maintenance. If properly planned, these anchorage points may be used 
during construction, as well as afterwards.
    (i) Properly planned anchorages should be used if they are 
available. In some cases, anchorages must be installed immediately 
prior to use. In such cases, a registered professional engineer with 
experience in designing fall protection systems, or another 
qualified person with appropriate education and experience should 
design an anchor point to be installed.
    (ii) In other cases, the Agency recognizes that there will be a 
need to devise an anchor point from existing structures. Examples of 
what might be appropriate anchor points are steel members or I-beams 
if an acceptable strap is available for the connection (do not use a 
lanyard with a snaphook clipped onto itself); large eye-bolts made 
of an appropriate grade steel; guardrails or railings if they have 
been designed for use as an anchor point; or masonry or wood members 
only if the attachment point is substantial and precautions have 
been taken to assure that bolts or other connectors will not pull 
through. A qualified person should be used to evaluate the suitable 
of these ``make shift'' anchorages with a focus on proper strength.
    (2) Employers and employees should at all times be aware that 
the strength of a personal fall arrest system is based on its being 
attached to an anchoring system which does not reduce the strength 
of the system (such as a properly dimensioned eye-bolt/snap-hook 
anchorage). Therefore, if a means of attachment is used that will 
reduce the strength of the system, that component should be replaced 
by a stronger one, but one that will also maintain the appropriate 
maximum arrest force characteristics.
    (3) Tie-off using a knot in a rope lanyard or lifeline (at any 
location) can reduce the lifeline or lanyard strength by 50 percent 
or more. Therefore, a stronger lanyard or lifeline should be used to 
compensate for the weakening effect of the knot, or the lanyard 
length should be reduced (or the tie-off location raised) to 
minimize free fall distance, or the lanyard or lifeline should be 
replaced by one which has an appropriately incorporated connector to 
eliminate the need for a knot.
    (4) Tie-off of a rope lanyard or lifeline around an ``H'' or 
``I'' beam or similar support can reduce its strength as much as 70 
percent due to the cutting action of the beam edges. Therefore, use 
should be made of a webbing lanyard or wire core lifeline around the 
beam; or the lanyard or lifeline should be protected from the edge; 
or free fall distance should be greatly minimized.
    (5) Tie-off where the line passes over or around rough or sharp 
surfaces reduces strength drastically. Such a tie-off should be 
avoided or an alternative tie-off rigging should be used. Such 
alternatives may include use of a snap-hook/dee ring connection, 
wire rope tie-off, an effective padding of the surfaces, or an 
abrasion-resistance strap around or over the problem surface.
    (6) Horizontal lifelines may, depending on their geometry and 
angle of sag, be subjected to greater loads than the impact load 
imposed by an attached component. When the angle of horizontal 
lifeline sag is less than 30 degrees, the impact force imparted to 
the lifeline by an attached lanyard is greatly amplified. For 
example, with a sag angle of 15 degrees, the force amplification is 
about 2:1 and at 5 degrees sag, it is about 6:1. Depending on the 
angle of sag, and the line's elasticity, the strength of the 
horizontal lifeline and the anchorages to which it is attached 
should be increased a number of times over that of the lanyard. 
Extreme care should be taken in considering a horizontal lifeline 
for multiple tie-offs. The reason for this is that in multiple tie-
offs to a horizontal lifeline, if one employee falls, the movement 
of the falling employee and the horizontal lifeline during arrest of 
the fall may cause other employees to fall also. Horizontal lifeline 
and anchorage strength should be increased for each additional 
employee to be tied off. For these and other reasons, the design of 
systems using horizontal lifelines must only be done by qualified 
persons. Testing of installed lifelines and anchors prior to use is 
recommended.
    (7) The strength of an eye-bolt is rated along the axis of the 
bolt and its strength is greatly reduced if the force is applied at 
an angle to this axis (in the direction of shear). Also, care should 
be exercised in selecting the proper diameter of the eye to avoid 
accidental disengagement of snap-hooks not designed to be compatible 
for the connection.
    (8) Due to the significant reduction in the strength of the 
lifeline/lanyard (in some cases, as much as a 70 percent reduction), 
the sliding hitch knot (prusik) should not be used for lifeline/
lanyard connections except in emergency situations where no other 
available system is practical. The ``one-and-one'' sliding hitch 
knot should never be used because it is unreliable in stopping a 
fall. The ``two-and-two,'' or ``three-and-three'' knot (preferable) 
may be used in emergency situations; however, care should be taken 
to limit free fall distance to a minimum because of reduced 
lifeline/lanyard strength.
    (i) Vertical lifeline considerations. As required by the 
standard, each employee must have a separate lifeline [except 
employees engaged in constructing elevator shafts who are permitted 
to have two employees on one lifeline] when the lifeline is 
vertical. The reason for this is that in multiple tie-offs to a 
single lifeline, if one employee falls, the movement of the lifeline 
during the arrest of the fall may pull other employees' lanyards, 
causing them to fall as well.
    (j) Snap-hook considerations. (1) Although not required by this 
standard for all connections until January 1, 1998, locking 
snaphooks designed for connection to suitable objects (of sufficient 
strength) are highly recommended in lieu of the nonlocking type. 
Locking snaphooks incorporate a positive locking mechanism in 
addition to the spring loaded keeper, which will not allow the 
keeper to open under moderate pressure without someone first 
releasing the mechanism. Such a feature, properly designed, 
effectively prevents roll-out from occurring.
    (2) As required by Sec. 1926.502(d)(6), the following 
connections must be avoided (unless properly designed locking 
snaphooks are used) because they are conditions which can result in 
roll-out when a nonlocking snaphook is used:
    (i) Direct connection of a snaphook to a horizontal lifeline.
    (ii) Two (or more) snaphooks connected to one dee-ring.
    (iii) Two snaphooks connected to each other.
    (iv) A snaphook connected back on its integral lanyard.
    (v) A snaphook connected to a webbing loop or webbing lanyard.
    (vi) Improper dimensions of the dee-ring, rebar, or other 
connection point in relation to the snaphook dimensions which would 
allow the snaphook keeper to be depressed by a turning motion of the 
snaphook.
    (k) Free fall considerations. The employer and employee should 
at all times be aware that a system's maximum arresting force is 
evaluated under normal use conditions established by the 
manufacturer, and in no case using a free fall distance in excess of 
6 feet (1.8 m). A few extra feet of free fall can significantly 
increase the arresting force on the employee, possibly to the point 
of causing injury. Because of this, the free fall distance should be 
kept at a minimum, and, as required by the standard, in no case 
greater than 6 feet (1.8 m). To help assure this, the tie-off 
attachment point to the lifeline or anchor should be located at or 
above the connection point of the fall arrest equipment to belt or 
harness. (Since otherwise additional free fall distance is added to 
the length of the connecting means (i.e. lanyard)). Attaching to the 
working surface will often result in a free fall greater than 6 feet 
(1.8 m). For instance, if a 6 foot (1.8 m) lanyard is used, the 
total free fall distance will be the distance from the working level 
to the body belt (or harness) attachment point plus the 6 feet (1.8 
m) of lanyard length. Another important consideration is that the 
arresting force which the fall system must withstand also goes up 
with greater distances of free fall, possibly exceeding the strength 
of the system.
    (l) Elongation and deceleration distance considerations. Other 
factors involved in a proper tie-off are elongation and deceleration 
distance. During the arresting of a fall, a lanyard will experience 
a length of stretching or elongation, whereas activation of a 
deceleration device will result in a certain stopping distance. 
These distances should be available with the lanyard or device's 
instructions and must be added to the free fall distance to arrive 
at the total fall distance before an employee is fully stopped. The 
additional stopping distance may be very significant if the lanyard 
or deceleration device is attached near or at the end of a long 
lifeline, which may itself add considerable distance due to its own 
elongation. As required by the standard, sufficient distance to 
allow for all of these factors must also be maintained between the 
employee and obstructions below, to prevent an injury due to impact 
before the system fully arrests the fall. In addition, a minimum of 
12 feet (3.7 m) of lifeline should be allowed below the securing 
point of a rope grab type deceleration device, and the end 
terminated to prevent the device from sliding off the lifeline. 
Alternatively, the lifeline should extend to the ground or the next 
working level below. These measures are suggested to prevent the 
worker from inadvertently moving past the end of the lifeline and 
having the rope grab become disengaged from the lifeline.
    (m) Obstruction considerations. The location of the tie-off 
should also consider the hazard of obstructions in the potential 
fall path of the employee. Tie-offs which minimize the possibilities 
of exaggerated swinging should be considered. In addition, when a 
body belt is used, the employee's body will go through a horizontal 
position to a jack-knifed position during the arrest of all falls. 
Thus, obstructions which might interfere with this motion should be 
avoided or a severe injury could occur.
    (n) Other considerations. Because of the design of some personal 
fall arrest systems, additional considerations may be required for 
proper tie-off. For example, heavy deceleration devices of the self-
retracting type should be secured overhead in order to avoid the 
weight of the device having to be supported by the employee. Also, 
if self- retracting equipment is connected to a horizontal lifeline, 
the sag in the lifeline should be minimized to prevent the device 
from sliding down the lifeline to a position which creates a swing 
hazard during fall arrest. In all cases, manufacturer's instructions 
should be followed.

Appendix D to Subpart M--Positioning Device Systems

Non-Mandatory Guidelines for Complying With Sec. 1926.502(e)

    I. Testing Methods For Positioning Device Systems. This appendix 
serves as a non-mandatory guideline to assist employers comply with 
the requirements for positioning device systems in Sec. 1926.502(e). 
Paragraphs (b), (c), (d) and (e) of Appendix C of subpart M relating 
to Sec. 1926.502(d)--Personal Fall Arrest Systems--set forth test 
procedures which may be used, along with the procedures listed 
below, to determine compliance with the requirements for positioning 
device systems in Sec. 1926.502(e) (3) and (4) of Subpart M.
    (a) General. (1) Single strap positioning devices shall have one 
end attached to a fixed anchorage and the other end connected to a 
body belt or harness in the same manner as they would be used to 
protect employees. Double strap positioning devices, similar to 
window cleaner's belts, shall have one end of the strap attached to 
a fixed anchorage and the other end shall hang free. The body belt 
or harness shall be attached to the strap in the same manner as it 
would be used to protect employees. The two strap ends shall be 
adjusted to their maximum span.
    (2) The fixed anchorage shall be rigid, and shall not have a 
deflection greater than .04 inches (1 mm) when a force of 2,250 
pounds (10 kN) is applied.
    (3) During the testing of all systems, a test weight of 250 
pounds plus or minus 3 pounds (113 kg plus or minus 1.6 kg) shall be 
used. The weight shall be a rigid object with a girth of 38 inches 
plus or minus 4 inches (96 cm plus or minus 10 cm).
    (4) Each test shall consist of dropping the specified weight one 
time without failure of the system being tested. A new system shall 
be used for each test.
    (5) The test weight for each test shall be hoisted exactly 4 
feet (1.2 m above its ``at rest'' position), and shall be dropped so 
as to permit a vertical free fall of 4 feet (1.2 m).
    (6) The test is failed whenever any breakage or slippage occurs 
which permits the weight to fall free of the system.
    (7) Following the test, the system need not be capable of 
further operation; however, all such incapacities shall be readily 
apparent.
    II. Inspection Considerations. As required in Sec. 1926.502 
(e)(5), positioning device systems must be regularly inspected. Any 
component with any significant defect, such as cuts, tears, 
abrasions, mold, or undue stretching; alterations or additions which 
might affect its efficiency; damage due to deterioration; contact 
with fire, acids, or other corrosives; distorted hooks or faulty 
hook springs; tongues unfitted to the shoulder of buckles; loose or 
damaged mountings; non-functioning parts; or wearing or internal 
deterioration in the ropes must be withdrawn from service 
immediately, and should be tagged or marked as unusable, or 
destroyed.

Appendix E to Subpart M--Sample Fall Protection Plan

Non-Mandatory Guidelines for Complying With Sec. 1926.502(k)

    Employers engaged in leading edge work, precast concrete 
construction work and residential construction work who can 
demonstrate that it is infeasible or creates a greater hazard to use 
conventional fall protection systems must develop and follow a fall 
protection plan. Below are sample fall protection plans developed 
for precast concrete construction and residential work that could be 
tailored to be site specific for other precast concrete or 
residential jobsite. This sample plan can be modified to be used for 
other work involving leading edge work. The sample plan outlines the 
elements that must be addressed in any fall protection plan. The 
reasons outlined in this sample fall protection plan are for 
illustrative purposes only and are not necessarily a valid, 
acceptable rationale (unless the conditions at the job site are the 
same as those covered by these sample plans) for not using 
conventional fall protection systems for a particular precast 
concrete or residential construction worksite. However, the sample 
plans provide guidance to employers on the type of information that 
is required to be discussed in fall protection plans.

Plan Prepared By-------------------------------------------------------
Plan Approved By-------------------------------------------------------
Plan Supervised By-----------------------------------------------------

    The following Fall Protection Plan is a sample program prepared 
for the prevention of injuries associated with falls. A Fall 
Protection Plan must be developed and evaluated on a site by site 
basis. It is recommended that erectors discuss the written Fall 
Protection Plan with their OSHA Area Office prior to going on a 
jobsite.

I. Statement of Company Policy

    (Company Name) is dedicated to the protection of its employees 
from on-the-job injuries. All employees of (Company Name) have the 
responsibility to work safely on the job. The purpose of this plan 
is: (a) To supplement our standard safety policy by providing safety 
standards specifically designed to cover fall protection on this job 
and; (b) to ensure that each employee is trained and made aware of 
the safety provisions which are to be implemented by this plan prior 
to the start of erection.
    This Fall Protection Plan addresses the use of other than 
conventional fall protection at a number of areas on the project, as 
well as identifying specific activities that require non-
conventional means of fall protection. These areas include:
    a. Connecting activity (point of erection).
    b. Leading edge work.
    c. Unprotected sides or edge.
    d. Grouting.
    This plan is designed to enable employers and employees to 
recognize the fall hazards on this job and to establish the 
procedures that are to be followed in order to prevent falls to 
lower levels or through holes and openings in walking/working 
surfaces. Each employee will be trained in these procedures and 
strictly adhere to them except when doing so would expose the 
employee to a greater hazard. If, in the employees opinion, this is 
the case, the employee is to notify the foreman of the concern and 
the concern addressed before proceeding.
    Safety policy and procedure on any one project cannot be 
administered, implemented, monitored and enforced by any one 
individual. The total objective of a safe, accident free work 
environment can only be accomplished by a dedicated, concerted 
effort by every individual involved with the project from management 
down to the last employee. Each employee must understand their value 
to the company; the costs of accidents, both monetary, physical, and 
emotional; the objective of the safety policy and procedures; the 
safety rules that apply to the safety policy and procedures; and 
what their individual role is in administering, implementing, 
monitoring, and compliance of their safety policy and procedures. 
This allows for a more personal approach to compliance through 
planning, training, understanding and cooperative effort, rather 
than by strict enforcement. If for any reason an unsafe act 
persists, strict enforcement will be implemented.
    It is the responsibility of (name of competent person) to 
implement this Fall Protection Plan. (Name of Competent Person) is 
responsible for continual observational safety checks of their work 
operations and to enforce the safety policy and procedures. The 
foreman also is responsible to correct any unsafe acts or conditions 
immediately. It is the responsibility of the employee to understand 
and adhere to the procedures of this plan and to follow the 
instructions of the foreman. It is also the responsibility of the 
employee to bring to managements attention any unsafe or hazardous 
conditions or acts that may cause injury to either themselves or any 
other employees. Any changes to this Fall Protection Plan must be 
approved by (name of Qualified Person).

II. Fall Protection Systems to Be Used on This Project

    Where conventional fall protection is infeasible or creates a 
greater hazard at the leading edge and during initial connecting 
activity, we plan to do this work using a safety monitoring system 
and expose only a minimum number of employees for the time necessary 
to actually accomplish the job. The maximum number of workers to be 
monitored by one safety monitor is six (6). We are designating the 
following trained employees as designated erectors and they are 
permitted to enter the controlled access zones and work without the 
use of conventional fall protection.

Safety monitor:
Designated erector:
Designated erector:
Designated erector:
Designated erector:
Designated erector:
Designated erector:

    The safety monitor shall be identified by wearing an orange hard 
hat. The designated erectors will be identified by one of the 
following methods:
    1. They will wear a blue colored arm band, or
    2. They will wear a blue colored hard hat, or
     3. They will wear a blue colored vest.

Only individuals with the appropriate experience, skills, and 
training will be authorized as designated erectors. All employees 
that will be working as designated erectors under the safety 
monitoring system shall have been trained and instructed in the 
following areas:
    1. Recognition of the fall hazards in the work area (at the 
leading edge and when making initial connections--point of 
erection).
    2. Avoidance of fall hazards using established work practices 
which have been made known to the employees.
    3. Recognition of unsafe practices or working conditions that 
could lead to a fall, such as windy conditions.
    4. The function, use, and operation of safety monitoring 
systems, guardrail systems, body belt/harness systems, control zones 
and other protection to be used.
    5. The correct procedure for erecting, maintaining, 
disassembling and inspecting the system(s) to be used.
     6. Knowledge of construction sequence or the erection plan.
    A conference will take place prior to starting work involving 
all members of the erection crew, crane crew and supervisors of any 
other concerned contractors. This conference will be conducted by 
the precast concrete erection supervisor in charge of the project. 
During the pre-work conference, erection procedures and sequences 
pertinent to this job will be thoroughly discussed and safety 
practices to be used throughout the project will be specified. 
Further, all personnel will be informed that the controlled access 
zones are off limits to all personnel other than those designated 
erectors specifically trained to work in that area.

Safety Monitoring System

    A safety monitoring system means a fall protection system in 
which a competent person is responsible for recognizing and warning 
employees of fall hazards. The duties of the safety monitor are to:
    1. Warn by voice when approaching the open edge in an unsafe 
manner.
    2. Warn by voice if there is a dangerous situation developing 
which cannot be seen by another person involved with product 
placement, such as a member getting out of control.
    3. Make the designated erectors aware they are in a dangerous 
area.
    4. Be competent in recognizing fall hazards.
    5. Warn employees when they appear to be unaware of a fall 
hazard or are acting in an unsafe manner.
     6. Be on the same walking/working surface as the monitored 
employees and within visual sighting distance of the monitored 
employees.
    7. Be close enough to communicate orally with the employees.
    8. Not allow other responsibilities to encumber monitoring. If 
the safety monitor becomes too encumbered with other 
responsibilities, the monitor shall (1) stop the erection process; 
and (2) turn over other responsibilities to a designated erector; or 
(3) turn over the safety monitoring function to another designated, 
competent person. The safety monitoring system shall not be used 
when the wind is strong enough to cause loads with large surface 
areas to swing out of radius, or result in loss of control of the 
load, or when weather conditions cause the walking-working surfaces 
to become icy or slippery.

Control Zone System

    A controlled access zone means an area designated and clearly 
marked, in which leading edge work may take place without the use of 
guardrail, safety net or personal fall arrest systems to protect the 
employees in the area. Control zone systems shall comply with the 
following provisions:
    1. When used to control access to areas where leading edge and 
other operations are taking place the controlled access zone shall 
be defined by a control line or by any other means that restricts 
access.
    When control lines are used, they shall be erected not less than 
6 feet (l.8 m) nor more than 60 feet (18 m) or half the length of 
the member being erected, whichever is less, from the leading edge.
    2. The control line shall extend along the entire length of the 
unprotected or leading edge and shall be approximately parallel to 
the unprotected or leading edge.
    3. The control line shall be connected on each side to a 
guardrail system or wall.
    4. Control lines shall consist of ropes, wires, tapes, or 
equivalent materials, and supporting stanchions as follows:
    5. Each line shall be flagged or otherwise clearly marked at not 
more than 6-foot (1.8 m) intervals with high- visibility material.
    6. Each line shall be rigged and supported in such a way that 
its lowest point (including sag) is not less than 39 inches (1 m) 
from the walking/working surface and its highest point is not more 
than 45 inches (1.3 m) from the walking/working surface.
    7. Each line shall have a minimum breaking strength of 200 
pounds (.88 kN).

Holes

    All openings greater than 12 in. x 12 in. will have perimeter 
guarding or covering. All predetermined holes will have the plywood 
covers made in the precasters' yard and shipped with the member to 
the jobsite. Prior to cutting holes on the job, proper protection 
for the hole must be provided to protect the workers. Perimeter 
guarding or covers will not be removed without the approval of the 
erection foreman.
    Precast concrete column erection through the existing deck 
requires that many holes be provided through this deck. These are to 
be covered and protected. Except for the opening being currently 
used to erect a column, all opening protection is to be left 
undisturbed. The opening being uncovered to erect a column will 
become part of the point of erection and will be addressed as part 
of this Fall Protection Plan. This uncovering is to be done at the 
erection foreman's direction and will only occur immediately prior 
to ``feeding'' the column through the opening. Once the end of the 
column is through the slab opening, there will no longer exist a 
fall hazard at this location.

III. Implementation of Fall Protection Plan

    The structure being erected is a multistory total precast 
concrete building consisting of columns, beams, wall panels and 
hollow core slabs and double tee floor and roof members.
    The following is a list of the products and erection situations 
on this job:

Columns

    For columns 10 ft to 36 ft long, employees disconnecting crane 
hooks from columns will work from a ladder and wear a body belt/
harness with lanyard and be tied off when both hands are needed to 
disconnect. For tying off, a vertical lifeline will be connected to 
the lifting eye at the top of the column, prior to lifting, to be 
used with a manually operated or mobile rope grab. For columns too 
high for the use of a ladder, 36 ft and higher, an added cable will 
be used to reduce the height of the disconnecting point so that a 
ladder can be used. This cable will be left in place until a point 
in erection that it can be removed safely. In some cases, columns 
will be unhooked from the crane by using an erection tube or shackle 
with a pull pin which is released from the ground after the column 
is stabilized.
    The column will be adequately connected and/or braced to safely 
support the weight of a ladder with an employee on it.

Inverted Tee Beams

    Employees erecting inverted tee beams, at a height of 6 to 40 
ft, will erect the beam, make initial connections, and final 
alignment from a ladder. If the employee needs to reach over the 
side of the beam to bar or make an adjustment to the alignment of 
the beam, they will mount the beam and be tied off to the lifting 
device in the beam after ensuring the load has been stabilized on 
its bearing. To disconnect the crane from the beam an employee will 
stand a ladder against the beam. Because the use of ladders is not 
practical at heights above 40 ft, beams will be initially placed 
with the use of tag lines and their final alignment made by a person 
on a manlift or similar employee positioning systems.

Spandrel Beams

    Spandrel beams at the exterior of the building will be aligned 
as closely as possible with the use of tag lines with the final 
placement of the spandrel beam made from a ladder at the open end of 
the structure. A ladder will be used to make the initial connections 
and a ladder will be used to disconnect the crane. The other end of 
the beam will be placed by the designated erector from the double 
tee deck under the observation of the safety monitor.
    The beams will be adequately connected and/or braced to safely 
support the weight of a ladder with an employee on it.

Floor and Roof Members

    During installation of the precast concrete floor and/or roof 
members, the work deck continuously increases in area as more and 
more units are being erected and positioned. Thus, the unprotected 
floor/roof perimeter is constantly modified with the leading edge 
changing location as each member is installed. The fall protection 
for workers at the leading edge shall be assured by properly 
constructed and maintained control zone lines not more than 60 ft 
away from the leading edge supplemented by a safety monitoring 
system to ensure the safety of all designated erectors working 
within the area defined by the control zone lines.
    The hollow core slabs erected on the masonry portion of the 
building will be erected and grouted using the safety monitoring 
system. Grout will be placed in the space between the end of the 
slab and face shell of the concrete masonry by dumping from a 
wheelbarrow. The grout in the keyways between the slabs will be 
dumped from a wheelbarrow and then spread with long handled tools, 
allowing the worker to stand erect facing toward the unprotected 
edge and back from any work deck edge.
    Whenever possible, the designated erectors will approach the 
incoming member at the leading edge only after it is below waist 
height so that the member itself provides protection against falls.
    Except for the situations described below, when the arriving 
floor or roof member is within 2 to 3 inches of its final position, 
the designated erectors can then proceed to their position of 
erection at each end of the member under the control of the safety 
monitor. Crane hooks will be unhooked from double tee members by 
designated erectors under the direction and supervision of the 
safety monitor.
    Designated erectors, while waiting for the next floor or roof 
member, will be constantly under the control of the safety monitor 
for fall protection and are directed to stay a minimum of six (6) ft 
from the edge. In the event a designated erector must move from one 
end of a member, which has just been placed at the leading edge, 
they must first move away from the leading edge a minimum of six (6) 
ft and then progress to the other end while maintaining the minimum 
distance of six (6) ft at all times.
    Erection of double tees, where conditions require bearing of one 
end into a closed pocket and the other end on a beam ledge, 
restricting the tee legs from going directly into the pockets, 
require special considerations. The tee legs that are to bear in the 
closed pocket must hang lower than those at the beam bearing. The 
double tee will be ``two-lined'' in order to elevate one end higher 
than the other to allow for the low end to be ducked into the closed 
pocket using the following procedure.
    The double tee will be rigged with a standard four-way spreader 
off of the main load line. An additional choker will be attached to 
the married point of the two-legged spreader at the end of the tee 
that is to be elevated. The double tee will be hoisted with the main 
load line and swung into a position as close as possible to the 
tee's final bearing elevation. When the tee is in this position and 
stabilized, the whip line load block will be lowered to just above 
the tee deck. At this time, two erectors will walk out on the 
suspended tee deck at midspan of the tee member and pull the load 
block to the end of the tee to be elevated and attach the additional 
choker to the load block. The possibility of entanglement with the 
crane lines and other obstacles during this two lining process while 
raising and lowering the crane block on that second line could be 
hazardous to an encumbered employee. Therefore, the designated 
erectors will not tie off during any part of this process. While the 
designated erectors are on the double tee, the safety monitoring 
system will be used. After attaching the choker, the two erectors 
then step back on the previously erected tee deck and signal the 
crane operator to hoist the load with the whip line to the elevation 
that will allow for enough clearance to let the low end tee legs 
slide into the pockets when the main load line is lowered. The 
erector, who is handling the lowered end of the tee at the closed 
pocket bearing, will step out on the suspended tee. An erection bar 
will then be placed between the end of the tee leg and the inside 
face of the pocketed spandrel member. The tee is barred away from 
the pocketed member to reduce the friction and lateral force against 
the pocketed member. As the tee is being lowered, the other erector 
remains on the tee which was previously erected to handle the other 
end. At this point the tee is slowly lowered by the crane to a point 
where the tee legs can freely slide into the pockets. The erector 
working the lowered end of the tee must keep pressure on the bar 
between the tee and the face of the pocketed spandrel member to very 
gradually let the tee legs slide into the pocket to its proper 
bearing dimension. The tee is then slowly lowered into its final 
erected position.
    The designated erector should be allowed onto the suspended 
double tee, otherwise there is no control over the horizontal 
movement of the double tee and this movement could knock the 
spandrel off of its bearing or the column out of plumb. The control 
necessary to prevent hitting the spandrel can only be done safely 
from the top of the double tee being erected.
    Loadbearing Wall Panels: The erection of the loadbearing wall 
panels on the elevated decks requires the use of a safety monitor 
and a controlled access zone that is a minimum of 25 ft and a 
maximum of \1/2\ the length of the wall panels away from the 
unprotected edge, so that designated erectors can move freely and 
unencumbered when receiving the panels. Bracing, if required for 
stability, will be installed by ladder. After the braces are 
secured, the crane will be disconnected from the wall by using a 
ladder. The wall to wall connections will also be performed from a 
ladder.
    Non-Loadbearing Panels (Cladding): The locating of survey lines, 
panel layout and other installation prerequisites (prewelding, etc.) 
for non-loadbearing panels (cladding) will not commence until floor 
perimeter and floor openings have been protected. In some areas, it 
is necessary because of panel configuration to remove the perimeter 
protection as the cladding is being installed. Removal of perimeter 
protection will be performed on a bay to bay basis, just ahead of 
cladding erection to minimize temporarily unprotected floor edges. 
Those workers within 6 ft of the edge, receiving and positioning the 
cladding when the perimeter protection is removed shall be tied off.

Detailing

    Employees exposed to falls of six (6) feet or more to lower 
levels, who are not actively engaged in leading edge work or 
connecting activity, such as welding, bolting, cutting, bracing, 
guying, patching, painting or other operations, and who are working 
less than six (6) ft from an unprotected edge will be tied off at 
all times or guardrails will be installed. Employees engaged in 
these activities but who are more than six (6) ft from an 
unprotected edge as defined by the control zone lines, do not 
require fall protection but a warning line or control lines must be 
erected to remind employees they are approaching an area where fall 
protection is required.

IV. Conventional Fall Protection Considered for the Point of Erection 
or Leading Edge Erection Operations

A. Personal Fall Arrest Systems

    In this particular erection sequence and procedure, personal 
fall arrest systems requiring body belt/harness systems, lifelines 
and lanyards will not reduce possible hazards to workers and will 
create offsetting hazards during their usage at the leading edge of 
precast/prestressed concrete construction.
    Leading edge erection and initial connections are conducted by 
employees who are specifically trained to do this type of work and 
are trained to recognize the fall hazards. The nature of such work 
normally exposes the employee to the fall hazard for a short period 
of time and installation of fall protection systems for a short 
duration is not feasible because it exposes the installers of the 
system to the same fall hazard, but for a longer period of time.
    1. It is necessary that the employee be able to move freely 
without encumbrance in order to guide the sections of precast 
concrete into their final position without having lifelines attached 
which will restrict the employees ability to move about at the point 
of erection.
    2. A typical procedure requires 2 or more workers to maneuver 
around each other as a concrete member is positioned to fit into the 
structure. If they are each attached to a lifeline, part of their 
attention must be diverted from their main task of positioning a 
member weighing several tons to the task of avoiding entanglements 
of their lifelines or avoiding tripping over lanyards. Therefore, if 
these workers are attached to lanyards, more fall potential would 
result than from not using such a device.
    In this specific erection sequence and procedure, retractable 
lifelines do not solve the problem of two workers becoming tangled. 
In fact, such a tangle could prevent the lifeline from retracting as 
the worker moved, thus potentially exposing the worker to a fall 
greater than 6 ft. Also, a worker crossing over the lifeline of 
another worker can create a hazard because the movement of one 
person can unbalance the other. In the event of a fall by one person 
there is a likelihood that the other person will be caused to fall 
as well. In addition, if contamination such as grout (during hollow 
core grouting) enters the retractable housing it can cause excessive 
wear and damage to the device and could clog the retracting 
mechanism as the lanyard is dragged across the deck. Obstructing the 
cable orifice can defeat the devices shock absorbing function, 
produce cable slack and damage, and adversely affect cable 
extraction and retraction.
    3. Employees tied to a lifeline can be trapped and crushed by 
moving structural members if the employee becomes restrained by the 
lanyard or retractable lifeline and cannot get out of the path of 
the moving load.
    The sudden movement of a precast concrete member being raised by 
a crane can be caused by a number of factors. When this happens, a 
connector may immediately have to move a considerable distance to 
avoid injury. If a tied off body belt/harness is being used, the 
connector could be trapped. Therefore, there is a greater risk of 
injury if the connector is tied to the structure for this specific 
erection sequence and procedure.
    When necessary to move away from a retractable device, the 
worker cannot move at a rate greater than the device locking speed 
typically 3.5 to 4.5 ft/sec. When moving toward the device it is 
necessary to move at a rate which does not permit cable slack to 
build up. This slack may cause cable retraction acceleration and 
cause a worker to lose their balance by applying a higher than 
normal jerking force on the body when the cable suddenly becomes 
taut after building up momentum. This slack can also cause damage to 
the internal spring-loaded drum, uneven coiling of cable on the 
drum, and possible cable damage.
    The factors causing sudden movements for this location include:

(a) Cranes

    (1) Operator error.
    (2) Site conditions (soft or unstable ground).
    (3) Mechanical failure.
    (4) Structural failure.
    (5) Rigging failure.
    (6) Crane signal/radio communication failure.

(b) Weather Conditions

    (1) Wind (strong wind/sudden gusting)--particularly a problem 
with the large surface areas of precast concrete members.
    (2) Snow/rain (visibility).
    (3) Fog (visibility).
    (4) Cold--causing slowed reactions or mechanical problems.
    (c) Structure/Product Conditions.
    (1) Lifting Eye failure.
    (2) Bearing failure or slippage.
    (3) Structure shifting.
    (4) Bracing failure.
    (5) Product failure.
    (d) Human Error.
    (1) Incorrect tag line procedure.
    (2) Tag line hang-up.
    (3) Incorrect or misunderstood crane signals.
    (4) Misjudged elevation of member.
    (5) Misjudged speed of member.
    (6) Misjudged angle of member.
    4. Anchorages or special attachment points could be cast into 
the precast concrete members if sufficient preplanning and 
consideration of erectors position is done before the members are 
cast. Any hole or other attachment must be approved by the engineer 
who designed the member. It is possible that some design 
restrictions will not allow a member to be weakened by an additional 
hole; however, it is anticipated that such situations would be the 
exception, not the rule. Attachment points, other than on the deck 
surface, will require removal and/or patching. In order to remove 
and/or patch these points, requires the employee to be exposed to an 
additional fall hazard at an unprotected perimeter. The fact that 
attachment points could be available anywhere on the structure does 
not eliminate the hazards of using these points for tying off as 
discussed above. A logical point for tying off on double tees would 
be using the lifting loops, except that they must be cut off to 
eliminate a tripping hazard at an appropriate time.
    5. Providing attachment at a point above the walking/working 
surface would also create fall exposures for employees installing 
their devices. Final positioning of a precast concrete member 
requires it to be moved in such a way that it must pass through the 
area that would be occupied by the lifeline and the lanyards 
attached to the point above. Resulting entanglements of lifelines 
and lanyards on a moving member could pull employees from the work 
surface. Also, the structure is being created and, in most cases, 
there is no structure above the members being placed.
    (a) Temporary structural supports, installed to provide 
attaching points for lifelines limit the space which is essential 
for orderly positioning, alignment and placement of the precast 
concrete members. To keep the lanyards a reasonable and manageable 
length, lifeline supports would necessarily need to be in proximity 
to the positioning process. A sudden shift of the precast concrete 
member being positioned because of wind pressure or crane movement 
could make it strike the temporary supporting structure, moving it 
suddenly and causing tied off employees to fall.
    (b) The time in manhours which would be expended in placing and 
maintaining temporary structural supports for lifeline attaching 
points could exceed the expended manhours involved in placing the 
precast concrete members. No protection could be provided for the 
employees erecting the temporary structural supports and these 
supports would have to be moved for each successive step in the 
construction process, thus greatly increasing the employees exposure 
to the fall hazard.
    (c) The use of a cable strung horizontally between two columns 
to provide tie off lines for erecting or walking a beam for 
connecting work is not feasible and creates a greater hazard on this 
multi-story building for the following reasons:
    (1) If a connector is to use such a line, it must be installed 
between the two columns. To perform this installation requires an 
erector to have more fall exposure time attaching the cable to the 
columns than would be spent to make the beam to column connection 
itself.
    (2) If such a line is to be installed so that an erector can 
walk along a beam, it must be overhead or below him. For example, if 
a connector must walk along a 24 in. wide beam, the presence of a 
line next to the connector at waist level, attached directly to the 
columns, would prevent the connector from centering their weight 
over the beam and balancing themselves. Installing the line above 
the connector might be possible on the first level of a two-story 
column; however, the column may extend only a few feet above the 
floor level at the second level or be flush with the floor level. 
Attaching the line to the side of the beam could be a solution; 
however, it would require the connector to attach the lanyard below 
foot level which would most likely extend a fall farther than 6 ft.
    (3) When lines are strung over every beam, it becomes more and 
more difficult for the crane operator to lower a precast concrete 
member into position without the member becoming fouled. Should the 
member become entangled, it could easily dislodge the line from a 
column. If a worker is tied to it at the time, a fall could be 
caused.
    6. The ANSI A10.14-1991 American National Standard for 
Construction and Demolition Operations--Requirements for Safety 
Belts, Harnesses, Lanyards and Lifelines for Construction and 
Demolition Use, states that the anchor point of a lanyard or 
deceleration device should, if possible, be located above the 
wearer's belt or harness attachment. ANSI A10.14 also states that a 
suitable anchorage point is one which is located as high as possible 
to prevent contact with an obstruction below should the worker fall. 
Most manufacturers also warn in the user's handbook that the safety 
block/retractable lifeline must be positioned above the D-ring 
(above the work space of the intended user) and OSHA recommends that 
fall arrest and restraint equipment be used in accordance with the 
manufacturer's instructions.
    Attachment of a retractable device to a horizontal cable near 
floor level or using the inserts in the floor or roof members may 
result in increased free fall due to the dorsal D-ring of the full-
body harness riding higher than the attachment point of the snaphook 
to the cable or insert (e.g., 6 foot tall worker with a dorsal D-
ring at 5 feet above the floor or surface, reduces the working 
length to only one foot, by placing the anchorage five feet away 
from the fall hazard). In addition, impact loads may exceed maximum 
fall arrest forces (MAF) because the fall arrest D-ring would be 4 
to 5 feet higher than the safety block/retractable lifeline anchored 
to the walking-working surface; and the potential for swing hazards 
is increased.
    Manufacturers also require that workers not work at a level 
where the point of snaphook attachment to the body harness is above 
the device because this will increase the free fall distance and the 
deceleration distance and will cause higher forces on the body in 
the event of an accidental fall.
    Manufacturers recommend an anchorage for the retractable 
lifeline which is immovably fixed in space and is independent of the 
user's support systems. A moveable anchorage is one which can be 
moved around (such as equipment or wheeled vehicles) or which can 
deflect substantially under shock loading (such as a horizontal 
cable or very flexible beam). In the case of a very flexible 
anchorage, a shock load applied to the anchorage during fall arrest 
can cause oscillation of the flexible anchorage such that the 
retractable brake mechanism may undergo one or more cycles of 
locking/unlocking/locking (ratchet effect) until the anchorage 
deflection is dampened. Therefore, use of a moveable anchorage 
involves critical engineering and safety factors and should only be 
considered after fixed anchorage has been determined to be not 
feasible.
    Horizontal cables used as an anchorage present an additional 
hazard due to amplification of the horizontal component of maximum 
arrest force (of a fall) transmitted to the points where the 
horizontal cable is attached to the structure. This amplification is 
due to the angle of sag of a horizontal cable and is most severe for 
small angles of sag. For a cable sag angle of 2 degrees the 
horizontal force on the points of cable attachment can be amplified 
by a factor of 15.
    It is also necessary to install the retractable device 
vertically overhead to minimize swing falls. If an object is in the 
worker's swing path (or that of the cable) hazardous situations 
exist: (1) due to the swing, horizontal speed of the user may be 
high enough to cause injury when an obstacle in the swing fall path 
is struck by either the user or the cable; (2) the total vertical 
fall distance of the user may be much greater than if the user had 
fallen only vertically without a swing fall path.
    With retractable lines, overconfidence may cause the worker to 
engage in inappropriate behavior, such as approaching the perimeter 
of a floor or roof at a distance appreciably greater than the 
shortest distance between the anchorage point and the leading edge. 
Though the retractable lifeline may arrest a worker's fall before he 
or she has fallen a few feet, the lifeline may drag along the edge 
of the floor or beam and swing the worker like a pendulum until the 
line has moved to a position where the distance between the 
anchorage point and floor edge is the shortest distance between 
those two points. Accompanying this pendulum swing is a lowering of 
the worker, with the attendant danger that he or she may violently 
impact the floor or some obstruction below.
    The risk of a cable breaking is increased if a lifeline is 
dragged sideways across the rough surface or edge of a concrete 
member at the same moment that the lifeline is being subjected to a 
maximum impact loading during a fall. The typical \3/16\ in. cable 
in a retractable lifeline has a breaking strength of from 3000 to 
3700 lbs.
    7. The competent person, who can take into account the 
specialized operations being performed on this project, should 
determine when and where a designated erector cannot use a personal 
fall arrest system.

B. Safety Net Systems

    The nature of this particular precast concrete erection worksite 
precludes the safe use of safety nets where point of erection or 
leading edge work must take place.
    1. To install safety nets in the interior high bay of the single 
story portion of the building poses rigging attachment problems. 
Structural members do not exist to which supporting devices for nets 
can be attached in the area where protection is required. As the 
erection operation advances, the location of point of erection or 
leading edge work changes constantly as each member is attached to 
the structure. Due to this constant change it is not feasible to set 
net sections and build separate structures to support the nets.
    2. The nature of the erection process for the precast concrete 
members is such that an installed net would protect workers as they 
position and secure only one structural member. After each member is 
stabilized the net would have to be moved to a new location (this 
could mean a move of 8 to 10 ft or the possibility of a move to a 
different level or area of the structure) to protect workers placing 
the next piece in the construction sequence. The result would be the 
installation and dismantling of safety nets repeatedly throughout 
the normal work day. As the time necessary to install a net, test, 
and remove it is significantly greater than the time necessary to 
position and secure a precast concrete member, the exposure time for 
the worker installing the safety net would be far longer than for 
the workers whom the net is intended to protect. The time exposure 
repeats itself each time the nets and supporting hardware must be 
moved laterally or upward to provide protection at the point of 
erection or leading edge.
    3. Strict interpretation of Sec. 1926.502(c) requires that 
operations shall not be undertaken until the net is in place and has 
been tested. With the point of erection constantly changing, the 
time necessary to install and test a safety net significantly 
exceeds the time necessary to position and secure the concrete 
member.
    4. Use of safety nets on exposed perimeter wall openings and 
opensided floors, causes attachment points to be left in 
architectural concrete which must be patched and filled with 
matching material after the net supporting hardware is removed. In 
order to patch these openings, additional numbers of employees must 
be suspended by swing stages, boatswain chairs or other devices, 
thereby increasing the amount of fall exposure time to employees.
    5. Installed safety nets pose an additional hazard at the 
perimeter of the erected structure where limited space is available 
in which members can be turned after being lifted from the ground by 
the crane. There would be a high probability that the member being 
lifted could become entangled in net hardware, cables, etc.
    6. The use of safety nets where structural wall panels are being 
erected would prevent movement of panels to point of installation. 
To be effective, nets would necessarily have to provide protection 
across the area where structural supporting wall panels would be set 
and plumbed before roof units could be placed.
    7. Use of a tower crane for the erection of the high rise 
portion of the structure poses a particular hazard in that the crane 
operator cannot see or judge the proximity of the load in relation 
to the structure or nets. If the signaler is looking through nets 
and supporting structural devices while giving instructions to the 
crane operator, it is not possible to judge precise relationships 
between the load and the structure itself or to nets and supporting 
structural devices. This could cause the load to become entangled in 
the net or hit the structure causing potential damage.

C. Guardrail Systems

    On this particular worksite, guardrails, barricades, ropes, 
cables or other perimeter guarding devices or methods on the 
erection floor will pose problems to safe erection procedures. 
Typically, a floor or roof is erected by placing 4 to 10 ft wide 
structural members next to one another and welding or grouting them 
together. The perimeter of a floor and roof changes each time a new 
member is placed into position. It is unreasonable and virtually 
impossible to erect guardrails and toe boards at the ever changing 
leading edge of a floor or roof.
    1. To position a member safely it is necessary to remove all 
obstructions extending above the floor level near the point of 
erection. Such a procedure allows workers to swing a new member 
across the erected surface as necessary to position it properly 
without worrying about knocking material off of this surface.
    Hollow core slab erection on the masonry wall requires 
installation of the perimeter protection where the masonry wall has 
to be constructed. This means the guardrail is installed then 
subsequently removed to continue the masonry construction. The 
erector will be exposed to a fall hazard for a longer period of time 
while installing and removing perimeter protection than while 
erecting the slabs.
    In hollow core work, as in other precast concrete erection, 
others are not typically on the work deck until the precast concrete 
erection is complete. The deck is not complete until the leveling, 
aligning, and grouting of the joints is done. It is normal practice 
to keep others off the deck until at least the next day after the 
installation is complete to allow the grout to harden.
    2. There is no permanent boundary until all structural members 
have been placed in the floor or roof. At the leading edge, workers 
are operating at the temporary edge of the structure as they work to 
position the next member in the sequence. Compliance with the 
standard would require a guardrail and toe board be installed along 
this edge. However, the presence of such a device would prevent a 
new member from being swung over the erected surface low enough to 
allow workers to control it safely during the positioning process. 
Further, these employees would have to work through the guardrail to 
align the new member and connect it to the structure. The guardrail 
would not protect an employee who must lean through it to do the 
necessary work, rather it would hinder the employee to such a degree 
that a greater hazard is created than if the guardrail were absent.
    3. Guardrail requirements pose a hazard at the leading edge of 
installed floor or roof sections by creating the possibility of 
employees being caught between guardrails and suspended loads. The 
lack of a clear work area in which to guide the suspended load into 
position for placement and welding of members into the existing 
structure creates still further hazards.
    4. Where erection processes require precast concrete stairways 
or openings to be installed as an integral part of the overall 
erection process, it must also be recognized that guardrails or 
handrails must not project above the surface of the erection floor. 
Such guardrails should be terminated at the level of the erection 
floor to avoid placing hazardous obstacles in the path of a member 
being positioned.

V. Other Fall Protection Measures Considered for This Job

    The following is a list and explanation of other fall protection 
measures available and an explanation of limitations for use on this 
particular jobsite. If during the course of erecting the building 
the employee sees an area that could be erected more safely by the 
use of these fall protection measures, the foreman should be 
notified.
    A. Scaffolds are not used because:
    1. The leading edge of the building is constantly changing and 
the scaffolding would have to be moved at very frequent intervals. 
Employees erecting and dismantling the scaffolding would be exposed 
to fall hazards for a greater length of time than they would by 
merely erecting the precast concrete member.
    2. A scaffold tower could interfere with the safe swinging of a 
load by the crane.
    3. Power lines, terrain and site do not allow for the safe use 
of scaffolding.
    B. Vehicle mounted platforms are not used because:
    1. A vehicle mounted platform will not reach areas on the deck 
that are erected over other levels.
    2. The leading edge of the building is usually over a lower 
level of the building and this lower level will not support the 
weight of a vehicle mounted platform.
    3. A vehicle mounted platform could interfere with the safe 
swinging of a load by the crane, either by the crane swinging the 
load over or into the equipment.
    4. Power lines and surrounding site work do not allow for the 
safe use of a vehicle mounted platform.
    C. Crane suspended personnel platforms are not used because:
    1. A second crane close enough to suspend any employee in the 
working and erecting area could interfere with the safe swinging of 
a load by the crane hoisting the product to be erected.
    2. Power lines and surrounding site work do not allow for the 
safe use of a second crane on the job.

VI. Enforcement

    Constant awareness of and respect for fall hazards, and 
compliance with all safety rules are considered conditions of 
employment. The jobsite Superintendent, as well as individuals in 
the Safety and Personnel Department, reserve the right to issue 
disciplinary warnings to employees, up to and including termination, 
for failure to follow the guidelines of this program.

VII. Accident Investigations

    All accidents that result in injury to workers, regardless of 
their nature, shall be investigated and reported. It is an integral 
part of any safety program that documentation take place as soon as 
possible so that the cause and means of prevention can be identified 
to prevent a reoccurrence.
    In the event that an employee falls or there is some other 
related, serious incident occurring, this plan shall be reviewed to 
determine if additional practices, procedures, or training need to 
be implemented to prevent similar types of falls or incidents from 
occurring.

VIII. Changes to Plan

    Any changes to the plan will be approved by (name of the 
qualified person). This plan shall be reviewed by a qualified person 
as the job progresses to determine if additional practices, 
procedures or training needs to be implemented by the competent 
person to improve or provide additional fall protection. Workers 
shall be notified and trained, if necessary, in the new procedures. 
A copy of this plan and all approved changes shall be maintained at 
the jobsite.

Sample Fall Protection Plan for Residential Construction

(Insert Company Name)

    This Fall Protection Plan Is Specific For The Following Project:

Location of Job--------------------------------------------------------
Date Plan Prepared or Modified-----------------------------------------
Plan Prepared By-------------------------------------------------------
Plan Approved By-------------------------------------------------------
Plan Supervised By-----------------------------------------------------

    The following Fall Protection Plan is a sample program prepared 
for the prevention of injuries associated with falls. A Fall 
Protection Plan must be developed and evaluated on a site by site 
basis. It is recommended that builders discuss the written Fall 
Protection Plan with their OSHA Area Office prior to going on a 
jobsite.

I. Statement of Company Policy

    (Your company name here) is dedicated to the protection of its 
employees from on-the-job injuries. All employees of (Your company 
name here) have the responsibility to work safely on the job. The 
purpose of the plan is to supplement our existing safety and health 
program and to ensure that every employee who works for (Your 
company name here) recognizes workplace fall hazards and takes the 
appropriate measures to address those hazards.
    This Fall Protection Plan addresses the use of conventional fall 
protection at a number of areas on the project, as well as 
identifies specific activities that require non-conventional means 
of fall protection. During the construction of residential buildings 
under 48 feet in height, it is sometimes infeasible or it creates a 
greater hazard to use conventional fall protection systems at 
specific areas or for specific tasks. The areas or tasks may 
include, but are not limited to:
    a. Setting and bracing of roof trusses and rafters;
    b. Installation of floor sheathing and joists;
    c. Roof sheathing operations; and
    d. Erecting exterior walls.
    In these cases, conventional fall protection systems may not be 
the safest choice for builders. This plan is designed to enable 
employers and employees to recognize the fall hazards associated 
with this job and to establish the safest procedures that are to be 
followed in order to prevent falls to lower levels or through holes 
and openings in walking/working surfaces.
    Each employee will be trained in these procedures and will 
strictly adhere to them except when doing so would expose the 
employee to a greater hazard. If, in the employee's opinion, this is 
the case, the employee is to notify the competent person of their 
concern and have the concern addressed before proceeding.
    It is the responsibility of (name of competent person) to 
implement this Fall Protection Plan. Continual observational safety 
checks of work operations and the enforcement of the safety policy 
and procedures shall be regularly enforced. The crew supervisor or 
foreman (insert name) is responsible for correcting any unsafe 
practices or conditions immediately.
    It is the responsibility of the employer to ensure that all 
employees understand and adhere to the procedures of this plan and 
to follow the instructions of the crew supervisor. It is also the 
responsibility of the employee to bring to management's attention 
any unsafe or hazardous conditions or practices that may cause 
injury to either themselves or any other employees. Any changes to 
the Fall Protection Plan must be approved by (name of qualified 
person).

II. Fall Protection Systems To Be Used on This Job

    Installation of roof trusses/rafters, exterior wall erection, 
roof sheathing, floor sheathing and joist/truss activities will be 
conducted by employees who are specifically trained to do this type 
of work and are trained to recognize the fall hazards. The nature of 
such work normally exposes the employee to the fall hazard for a 
short period of time. This Plan details how (Your company name here) 
will minimize these hazards.

Controlled Access Zones

    When using the Plan to implement the fall protection options 
available, workers must be protected through limited access to high 
hazard locations. Before any non-conventional fall protection 
systems are used as part of the work plan, a controlled access zone 
(CAZ) shall be clearly defined by the competent person as an area 
where a recognized hazard exists. The demarcation of the CAZ shall 
be communicated by the competent person in a recognized manner, 
either through signs, wires, tapes, ropes or chains.
    (Your company name here) shall take the following steps to 
ensure that the CAZ is clearly marked or controlled by the competent 
person:
     All access to the CAZ must be restricted to authorized 
entrants;
     All workers who are permitted in the CAZ shall be 
listed in the appropriate sections of the Plan (or be visibly 
identifiable by the competent person) prior to implementation;
     The competent person shall ensure that all protective 
elements of the CAZ be implemented prior to the beginning of work.

Installation Procedures for Roof Truss and Rafter Erection

    During the erection and bracing of roof trusses/rafters, 
conventional fall protection may present a greater hazard to 
workers. On this job, safety nets, guardrails and personal fall 
arrest systems will not provide adequate fall protection because the 
nets will cause the walls to collapse, while there are no suitable 
attachment or anchorage points for guardrails or personal fall 
arrest systems.
    On this job, requiring workers to use a ladder for the entire 
installation process will cause a greater hazard because the worker 
must stand on the ladder with his back or side to the front of the 
ladder. While erecting the truss or rafter the worker will need both 
hands to maneuver the truss and therefore cannot hold onto the 
ladder. In addition, ladders cannot be adequately protected from 
movement while trusses are being maneuvered into place. Many workers 
may experience additional fatigue because of the increase in 
overhead work with heavy materials, which can also lead to a greater 
hazard.
    Exterior scaffolds cannot be utilized on this job because the 
ground, after recent backfilling, cannot support the scaffolding. In 
most cases, the erection and dismantling of the scaffold would 
expose workers to a greater fall hazard than erection of the 
trusses/rafters.
    On all walls eight feet or less, workers will install interior 
scaffolds along the interior wall below the location where the 
trusses/rafters will be erected. ``Sawhorse'' scaffolds constructed 
of 46 inch sawhorses and 2x10 planks will often allow workers to be 
elevated high enough to allow for the erection of trusses and 
rafters without working on the top plate of the wall.
    In structures that have walls higher than eight feet and where 
the use of scaffolds and ladders would create a greater hazard, safe 
working procedures will be utilized when working on the top plate 
and will be monitored by the crew supervisor. During all stages of 
truss/rafter erection the stability of the trusses/rafters will be 
ensured at all times.
    (Your company name here) shall take the following steps to 
protect workers who are exposed to fall hazards while working from 
the top plate installing trusses/rafters:
     Only the following trained workers will be allowed to 
work on the top plate during roof truss or rafter installation:

----------------------------------------------------------------------
----------------------------------------------------------------------
----------------------------------------------------------------------

     Workers shall have no other duties to perform during 
truss/rafter erection procedures;
     All trusses/rafters will be adequately braced before 
any worker can use the truss/rafter as a support;
     Workers will remain on the top plate using the 
previously stabilized truss/rafter as a support while other trusses/
rafters are being erected;
     Workers will leave the area of the secured trusses only 
when it is necessary to secure another truss/rafter;
     The first two trusses/rafters will be set from ladders 
leaning on side walls at points where the walls can support the 
weight of the ladder; and
     A worker will climb onto the interior top plate via a 
ladder to secure the peaks of the first two trusses/rafters being 
set.
    The workers responsible for detaching trusses from cranes and/or 
securing trusses at the peaks traditionally are positioned at the 
peak of the trusses/rafters. There are also situations where workers 
securing rafters to ridge beams will be positioned on top of the 
ridge beam.
    (Your company name here) shall take the following steps to 
protect workers who are exposed to fall hazards while securing 
trusses/rafters at the peak of the trusses/ridge beam:
     Only the following trained workers will be allowed to 
work at the peak during roof truss or rafter installation:

----------------------------------------------------------------------
----------------------------------------------------------------------
----------------------------------------------------------------------

     Once truss or rafter installation begins, workers not 
involved in that activity shall not stand or walk below or adjacent 
to the roof opening or exterior walls in any area where they could 
be struck by falling objects;
     Workers shall have no other duties than securing/
bracing the trusses/ridge beam;
     Workers positioned at the peaks or in the webs of 
trusses or on top of the ridge beam shall work from a stable 
position, either by sitting on a ``ridge seat'' or other equivalent 
surface that provides additional stability or by positioning 
themselves in previously stabilized trusses/rafters and leaning into 
and reaching through the trusses/rafters;
     Workers shall not remain on or in the peak/ridge any 
longer than necessary to safely complete the task.

Roof Sheathing Operations

    Workers typically install roof sheathing after all trusses/
rafters and any permanent truss bracing is in place. Roof structures 
are unstable until some sheathing is installed, so workers 
installing roof sheathing cannot be protected from fall hazards by 
conventional fall protection systems until it is determined that the 
roofing system can be used as an anchorage point. At that point, 
employees shall be protected by a personal fall arrest system.
    Trusses/rafters are subject to collapse if a worker falls while 
attached to a single truss with a belt/harness. Nets could also 
cause collapse, and there is no place to attach guardrails.
    All workers will ensure that they have secure footing before 
they attempt to walk on the sheathing, including cleaning shoes/
boots of mud or other slip hazards.
    To minimize the time workers must be exposed to a fall hazard, 
materials will be staged to allow for the quickest installation of 
sheathing.
    (Your company name here) shall take the following steps to 
protect workers who are exposed to fall hazards while installing 
roof sheathing:
     Once roof sheathing installation begins, workers not 
involved in that activity shall not stand or walk below or adjacent 
to the roof opening or exterior walls in any area where they could 
be struck by falling objects;
     The competent person shall determine the limits of this 
area, which shall be clearly communicated to workers prior to 
placement of the first piece of roof sheathing;
     The competent person may order work on the roof to be 
suspended for brief periods as necessary to allow other workers to 
pass through such areas when this would not create a greater hazard;
     Only qualified workers shall install roof sheathing;
     The bottom row of roof sheathing may be installed by 
workers standing in truss webs;
     After the bottom row of roof sheathing is installed, a 
slide guard extending the width of the roof shall be securely 
attached to the roof. Slide guards are to be constructed of no less 
than nominal 4'' height capable of limiting the uncontrolled slide 
of workers. Workers should install the slide guard while standing in 
truss webs and leaning over the sheathing;
     Additional rows of roof sheathing may be installed by 
workers positioned on previously installed rows of sheathing. A 
slide guard can be used to assist workers in retaining their footing 
during successive sheathing operations; and
     Additional slide guards shall be securely attached to 
the roof at intervals not to exceed 13 feet as successive rows of 
sheathing are installed. For roofs with pitches in excess of 9-in-
12, slide guards will be installed at four-foot intervals.
     When wet weather (rain, snow, or sleet) are present, 
roof sheathing operations shall be suspended unless safe footing can 
be assured for those workers installing sheathing.
     When strong winds (above 40 miles per hour) are 
present, roof sheathing operations are to be suspended unless wind 
breakers are erected.

Installation of Floor Joists and Sheathing

    During the installation of floor sheathing/joists (leading edge 
construction), the following steps shall be taken to protect 
workers:
     Only the following trained workers will be allowed to 
install floor joists or sheathing:

----------------------------------------------------------------------
----------------------------------------------------------------------
----------------------------------------------------------------------

     Materials for the operations shall be conveniently 
staged to allow for easy access to workers;
     The first floor joists or trusses will be rolled into 
position and secured either from the ground, ladders or sawhorse 
scaffolds;
     Each successive floor joist or truss will be rolled 
into place and secured from a platform created from a sheet of 
plywood laid over the previously secured floor joists or trusses;
     Except for the first row of sheathing which will be 
installed from ladders or the ground, workers shall work from the 
established deck; and
     Any workers not assisting in the leading edge 
construction while leading edges still exist (e.g. cutting the 
decking for the installers) shall not be permitted within six feet 
of the leading edge under construction.
Erection of Exterior Walls
    During the construction and erection of exterior walls, 
employers shall take the following steps to protect workers:
     Only the following trained workers will be allowed to 
erect exterior walls:

----------------------------------------------------------------------
----------------------------------------------------------------------
----------------------------------------------------------------------

     A painted line six feet from the perimeter will be 
clearly marked prior to any wall erection activities to warn of the 
approaching unprotected edge;
     Materials for operations shall be conveniently staged 
to minimize fall hazards; and
     Workers constructing exterior walls shall complete as 
much cutting of materials and other preparation as possible away 
from the edge of the deck.

III. Enforcement

    Constant awareness of and respect for fall hazards, and 
compliance with all safety rules are considered conditions of 
employment. The crew supervisor or foreman, as well as individuals 
in the Safety and Personnel Department, reserve the right to issue 
disciplinary warnings to employees, up to and including termination, 
for failure to follow the guidelines of this program.

IV. Accident Investigations

    All accidents that result in injury to workers, regardless of 
their nature, shall be investigated and reported. It is an integral 
part of any safety program that documentation take place as soon as 
possible so that the cause and means of prevention can be identified 
to prevent a reoccurrence.
    In the event that an employee falls or there is some other 
related, serious incident occurring, this plan shall be reviewed to 
determine if additional practices, procedures, or training need to 
be implemented to prevent similar types of falls or incidents from 
occurring.

V. Changes to Plan

    Any changes to the plan will be approved by (name of the 
qualified person). This plan shall be reviewed by a qualified person 
as the job progresses to determine if additional practices, 
procedures or training needs to be implemented by the competent 
person to improve or provide additional fall protection. Workers 
shall be notified and trained, if necessary, in the new procedures. 
A copy of this plan and all approved changes shall be maintained at 
the jobsite.
