29 CFR Part 1910

[Docket No. S-015]

 

Electric Power Generation, Transmission, and Distribution; 
Electrical Protective Equipment; Final Rule; Stay of Enforcement and 
Correction

AGENCY: Occupational Safety and Health Administration (OSHA), 
Department of Labor.

ACTION: Final rule; stay of enforcement and correction.

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

SUMMARY: On January 31, 1994, OSHA issued a new standard addressing the 
work practices to be used during the operation and maintenance of 
electric power generation, transmission, and distribution facilities 
[59 FR 4320]. In that document, OSHA also revised the electrical 
protective equipment requirements contained in the General Industry 
Standards. This notice stays the enforcement of some of the 
requirements contained in the electric power generation standard, 
corrects language in the preamble explaining the standard, and corrects 
several errors in the standards.

DATES: OSHA is staying the enforcement of the following paragraphs of 
Sec. 1910.269 until November 1, 1994: (b)(1)(ii), (d) except for 
(d)(2)(i) and (d)(2)(iii), (e)(2), (e)(3), (j)(2)(iii), (l)(6)(iii), 
(m), (n)(3), (n)(4)(ii), (n)(8), (o) except for (o)(2)(i), (r)(1)(vi), 
(u)(1), (u)(4), (u)(5). OSHA is also staying the enforcement of 
paragraphs (n)(6) and (n)(7) of Sec. 1910.269 until November 1, 1994, 
but only insofar as they apply to lines and equipment operated at 600 
volts or less. Further, OSHA is staying the enforcement of paragraph 
(v)(11)(xii) of Sec. 1910.269 until February 1, 1996.
    The corrections to Sec. 1910.269 presented in this document become 
effective on June 30, 1994.

FOR FURTHER INFORMATION CONTACT: Mr. James F. Foster, U.S. Department 
of Labor, Occupational Safety and Health Administration, Room N3647, 
200 Constitution Ave., N.W., Washington, D.C. 20210 (202-219-8148).

SUPPLEMENTARY INFORMATION: On January 31, 1994, OSHA issued a new 
standard addressing the work practices to be used during the operation 
and maintenance of electric power generation, transmission, and 
distribution facilities. In that document, OSHA also revised the 
electrical protective equipment requirements contained in the General 
Industry Standards.

I. Correction of the Preamble: Clothing for Employees Working On or 
Near Exposed Energized Parts

    Paragraph (l)(6)(iii) of Sec. 1910.269 prohibits employees exposed 
to flames or arcs from wearing clothing that, when exposed to flames or 
arcs, could increase the extent of injury that would be sustained by 
the employees. In adopting this requirement in the final rule, OSHA 
relied on the evidence submitted to the record in determining what 
clothing would or would not be acceptable under the language of 
paragraph (l)(6)(iii). The preamble to the final rule discussed a 
portion of this evidence as follows:

    The requirement is intended to prohibit the types of fabrics 
shown in the Duke Power Company videotape to be expected to cause 
more severe injuries than would otherwise be anticipated. These 
include such untreated materials as polyester and rayon, unless the 
employee is otherwise protected from the effects of their burning. 
Natural fabrics, such as 100 percent cotton or wool, and synthetic 
materials that are flame resistant or flame retardant are acceptable 
under the final rule. (If and when a national consensus standard on 
clothing for electrical workers becomes available, OSHA will examine 
whether or not to revise the rule to require materials conforming to 
such a standard.) [59 FR 4389]

    It is clear from this discussion that OSHA relied heavily on the 
videotape produced by Duke Power Company and on the results of arc 
tests on clothing as shown in the videotape in its finding that 
clothing made from certain fabrics was prohibited and that clothing 
made from other fabrics was acceptable. It is also quite clear from the 
preamble quotation that the Agency intended the final rule ``to 
prohibit the types of fabrics shown in the Duke Power Company videotape 
to be expected to cause more severe injuries than would otherwise be 
anticipated.'' However, later in that same quotation, OSHA stated that 
``natural fabrics, such as 100 percent cotton or wool, and synthetic 
materials that are flame resistant or flame retardant are acceptable 
under the final rule.'' Several questions have been raised in the 
period after the promulgation of the rule in regard to this statement 
in the preamble. Interested parties have pointed out that the Duke 
videotape stated specifically:

    All the heavyweight natural fibers we tested performed well. 
Natural fibers are those found in nature, such as cotton, wool, 
silk, and linen. We did little testing with silk and linen since 
most people wouldn't wear them while doing electrical work, but we 
performed extensive tests with cottons and wools. Lightweight 
cottons and wools sometimes burned, but without the melting and 
sticking of synthetics. Heavyweight cottons, wools, and blends of 
the two did not burn. They actually seemed to insulate whatever they 
were covering from the heat of the arc. Heavyweight means that a 
material weighs at least 11 ounces per yard, like the fabric in a 
denim jacket.

    OSHA wrote Sec. 1910.269(l)(6)(iii) in performance-oriented 
language. That language prohibits any clothing that, when exposed to 
flame or arc, could increase the extent of injury sustained by an 
employee. Although the record that was in place when final 
Sec. 1910.269 was adopted did not provide sufficient information for 
the adoption of a rule specifying clothing that would actually protect 
an employee from both flames and arcs, the Agency concluded that the 
record did support a rule prohibiting clothing that could further 
injure a worker. In other words, OSHA adopted a rule that addresses 
whether or not the clothing worn by a worker would contribute to injury 
rather than a rule requiring personal protective equipment. As a 
result, to determine whether clothing made from a given material meets 
the standard, OSHA need only ascertain whether that material will 
ignite and continue to burn under the conditions to which an employee 
is exposed. If, under these conditions, a material will ignite and will 
continue to burn in the absence of an ignition source, then clothing 
made from such material is prohibited by Sec. 1910.269(l)(6)(iii), 
unless the clothing is worn in such a manner as to eliminate the hazard 
involved.
    The Duke videotape, which was the primary basis for OSHA's 
determination that clothing made from certain types of fabrics should 
be prohibited whenever an employee is exposed to the hazards of 
electric arc, states that clothing made from 11-ounce cotton would not 
ignite under the conditions present during their arc tests. Clothing 
made from lesser weights of cotton could ignite and, once ignited, 
would continue to burn after the arc ceased. Clearly, from this 
evidence in the rulemaking record, clothing made from cotton of less 
than 11 ounces will not meet the performance criteria given in the 
standard for employees exposed to conditions comparable to those in the 
Duke Power Company tests.1 Cotton of 11 ounces or more will not 
ignite and therefore does meet the requirement in 
Sec. 1910.269(l)(6)(iii) under the arc test conditions.
---------------------------------------------------------------------------

    \1\The conditions present during the Duke Power Company tests 
involved an 3800-ampere, 12-inch (approximate) electric arc that was 
approximately 12 inches from the material. The arc lasted for 10 
cycles, or 0.167 seconds.
---------------------------------------------------------------------------

    On the basis of this evidence in the rulemaking record, OSHA has 
concluded that clothing made from 100 percent cotton or wool will be 
acceptable if its weight is appropriate for the flame and electric arc 
conditions to which an employee could be exposed. Employers must make a 
determination of whether or not 100 percent cotton or wool clothing 
worn by a worker is acceptable under the conditions to which he or she 
could be exposed. The factors employers must consider in making this 
determination are: The weight of the material; the available current 
involved; the duration of exposure; the distance from any possible 
flames or arcs that might occur; and the presence of other flammable 
materials (such as flammable hydraulic fluid) that could be ignited in 
the presence of an arc and, in turn, ignite the clothing. Later in this 
document, OSHA is correcting the quoted sentence in the preamble to the 
final rule in order to clarify the Agency's intent in this matter. (It 
should be noted that OSHA is not revising either the rule in paragraph 
(l)(6)(iii) or the note following that paragraph. The fabrics listed in 
that note continue to be prohibited.)
    Clothing made from flame-retardant or flame-resistant materials is 
acceptable under the rule. Employers are encouraged to ensure that 
their employees wear such clothing if they will be exposed to the 
hazard of flame or electric arc. In this regard, it should also be 
noted that the American Society for Testing and Materials (ASTM) has 
adopted a new standard, ASTM F1506-1994, for clothing to be worn for 
the protection of electrical workers who could be exposed to the hazard 
of flame or electric arc. This standard, which has not yet incorporated 
an arc-resistance test, requires the fabric used in clothing to pass a 
vertical flame test (that is, the fabric must be flame retardant or 
flame resistant). In fact, when OSHA revises Sec. 1910.269 or its 
counterpart in the Construction Standards (Subpart V of Part 1926), the 
Agency will be required under the Occupational Safety and Health Act of 
1970 (OSH Act) to adopt a rule that, if it differs substantially from 
the ASTM standard, must better effectuate the purposes of the OSH Act 
than that consensus standard. Employers should keep these facts in mind 
when adopting rules relating to the clothing worn by their electric 
power generation, transmission, and distribution employees.
    OSHA will continue to encourage ASTM Committee F18 (the committee 
responsible for ASTM F 1506) to expedite their research and standards 
development activities with regard to protective clothing worn by 
electrical workers. The Agency will use the latest information 
available from the committee and from other sources in revising 
Sec. 1910.269(l)(6)(iii) in the future.

II. Stay of Enforcement of Certain Provisions of Sec. 1910.269

    The electrical protective equipment standard and the electric power 
generation, transmission, and distribution standard, except 
Sec. 1910.269(a)(2), became effective on May 31, 1994. The Edison 
Electric Institute (EEI) petitioned OSHA to delay the effective date of 
certain requirements of these two standards until January 31, 1995, 
when the training requirements of Sec. 1910.269(a)(2) become effective. 
It said that several provisions require the purchase of equipment that 
is not in sufficient supply for the entire universe of affected 
employers. EEI also contended that other provisions require the 
modification of equipment or installations and that employers will need 
more than the 120 days given in the notice of rulemaking to make these 
modifications. It asserted that still other requirements entail 
significant departure from normal company practice and that detailed 
training is required to implement these requirements. The general 
training requirements, it noted, do not become effective until January 
31, 1995. Lastly, it maintained that employers need more time to 
consult with OSHA to determine exactly what practices and procedures 
are acceptable under the new standards.
    OSHA has reviewed EEI's petition for delay in the effective date 
and has found it justified, in part. With respect to EEI's petition 
regarding requirements that necessitate the purchase of equipment that 
is in short supply, the Agency finds that it is unnecessary to provide 
any delay in enforcement of these requirements. It is OSHA policy to 
accept purchase orders dated before the effective date of a standard to 
be evidence of intent to comply with that standard. In such cases, the 
Agency does not issue citations or impose penalties on companies that 
have ordered but not yet received goods that are intended for 
compliance with OSHA requirements.
    A stay will be necessary for provisions requiring significant 
modifications in equipment or installations. If an alteration is 
necessary, these requirements will force an employer to plan and design 
the modification, purchase any necessary materials, and then install 
the appropriate modification. These adjustments will normally take more 
than the 120 days given in the notice of rulemaking to put into place.
    EEI has identified one provision requiring modifications to 
existing coal-handling installations that will take up to 2 years for 
employers to effectuate. Paragraph (v)(11)(xii) of Sec. 1910.269 
requires sources of ignition to be eliminated or controlled so as to 
prevent the ignition of combustible atmospheres associated with coal-
handling operations. EEI argues that extensive modifications will be 
necessary at many older power plants and that these changes will take 
up to 2 years to put into place.
    Therefore, a stay of enforcement of Sec. 1910.269(v)(11)(xii) is 
granted until February 1, 1996, and a stay of enforcement of the 
following paragraphs of Sec. 1910.269 is granted until November 1, 
1994: 

------------------------------------------------------------------------
             Paragraph                           Description            
------------------------------------------------------------------------
(e)(3).............................  Rescue equipment for enclosed      
                                      spaces.                           
(u)(1).............................  Access and working space for       
                                      electric equipment in substations.
(u)(4).............................  Guarding of rooms containing       
                                      electric supply equipment in      
                                      substations.                      
(u)(5).............................  Guarding of energized parts in     
                                      substations.                      
------------------------------------------------------------------------

    With respect to provisions that entail extensive changes in work 
practices or procedures necessitating substantial retraining of 
employees, OSHA agrees to delay enforcement until the training for any 
new practices or procedures can be completed for all affected 
employees. Having some employees, who have been trained in a new 
procedure, use that procedure while other employees, who are not 
familiar with the new procedure, use other work methods could provide 
less safety. For example, the lockout and tagging requirements of 
Sec. 1910.269(d) necessitate the adoption of specific procedures for 
the control of hazardous energy sources. OSHA anticipates that some 
employers will need to modify existing lockout and tagging procedures 
to effect compliance with paragraph (d). Although the Agency believes 
that most affected employers are already using programs for the control 
of hazardous energy sources, some employers may need to modify their 
practices to comply with the final rule and to protect their employees 
fully. However, if those modifications are put into effect before all 
employees have been trained in their use, errors and injuries could 
result. Additionally, some of the provisions that EEI identified as 
requiring substantial training efforts are specific training 
requirements. For example, Sec. 1910.269(e)(2) requires employees to be 
trained in the hazards of enclosed space entry, in enclosed space entry 
procedures, and in enclosed space rescue procedures. These provisions 
will also take longer than 120 days to implement.
    Therefore, for this reason, OSHA is staying the enforcement of the 
following paragraphs of Sec. 1910.269 until November 1, 1994:

------------------------------------------------------------------------
             Paragraph                           Description            
------------------------------------------------------------------------
(b)(1)(ii).........................  Training in cardio-pulmonary       
                                      resuscitation for employees at    
                                      fixed work locations.             
(d), except for (d)(2)(i) and (d)    Control of hazardous energy sources
 (2) (iii).                           (generation installations).       
(e)(2).............................  Enclosed space training.           
(j)(2)(iii)........................  Cleaning, repair, and testing of   
                                      live-line tools.                  
(m)................................  Deenergizing transmission and      
                                      distribution installations for the
                                      protection of employees.          
(o), except for (o)(2)(i)..........  High-voltage and high-power testing
                                      and test facilities.              
------------------------------------------------------------------------

    The remaining requirements for which EEI requested delay are those 
that it claims will need additional consultation with OSHA so that 
employers will know exactly what is required by the standard. Because 
the standard is written in terms of performance, rather than in terms 
specifying the means of compliance, employers are given flexibility in 
meeting the standard. However, sometimes it may not be clear whether or 
not a given method will comply with an individual provision. For 
example, employers will likely need more time to identify the types of 
clothing that will be acceptable under Sec. 1910.269(l)(6)(iii).
    Therefore, OSHA is staying the enforcement of the following 
paragraphs of Sec. 1910.269 until November 1, 1994:

------------------------------------------------------------------------
             Paragraph                           Description            
------------------------------------------------------------------------
(1)(6)(iii)........................  Clothing worn by employees working 
                                      on or near exposed energized      
                                      parts.                            
(n)(3).............................  Equipotential zone for protective  
                                      grounding.                        
(n)(4)(ii).........................  Impedance of protective grounding  
                                      devices.                          
(n)(6)\1\..........................  Order of connection of grounds.    
(n)(7)\1\..........................  Order of removal of grounds.       
(n)(8).............................  Additional precautions for         
                                      protective grounding.             
(r)(1)(vi).........................  Line-clearance tree trimming during
                                      and after storms and other        
                                      emergencies.                      
------------------------------------------------------------------------
\1\Only with respect to lines and equipment operating at 600 volts or   
  less.                                                                 

    OSHA emphasizes that the record is not being reopened on any of the 
delayed provisions of Sec. 1910.269. Revised Sec. 1910.137 and 
Sec. 1910.269 are final rules, and the Agency is not considering the 
modification of any of these requirements. Additionally, Sec. 1910.137 
and all paragraphs of Sec. 1910.269 other than paragraph (a)(2), which 
becomes effective on January 31, 1995, went into effect on May 31, 
1994, as scheduled.

PART 1910--[AMENDED]

    For the reasons set forth above, the following Note is added to 
Sec. 1910.269 immediately preceding the text of the section.


Sec. 1910.269  Electric power generation, transmission, and 
distribution.

    OSHA is staying the enforcement of the following paragraphs of 
Sec. 1910.269 until November 1, 1994: (b)(1)(ii), (d) except for 
(d)(2)(i) and (d)(2)(iii), (e)(2), (e)(3), (j)(2)(iii), (l)(6)(iii), 
(m), (n)(3), (n)(4)(ii), (n)(8), (o) except for (o)(2)(i), (r)(1)(vi), 
(u)(1), (u)(4), (u)(5). OSHA is also staying the enforcement of 
paragraphs (n)(6) and (n)(7) of Sec. 1910.269 until November 1, 1994, 
but only insofar as they apply to lines and equipment operated at 600 
volts or less. Further, OSHA is staying the enforcement of paragraph 
(v)(11)(xii) of Sec. 1910.269 until Februrary 1, 1996.

III. Corrections.

    Several provisions in Sec. 1910.269 contained minor typographical 
or grammatical errors. Additionally, several national consensus 
standards were approved and published by the American National 
Standards Institute (ANSI) and by ASTM shortly after the promulgation 
of revised Sec. 1910.137 and Sec. 1910.269. Some non-mandatory notes 
and a non-mandatory appendix contained references to older editions of 
these ASTM standards. These non-mandatory references are intended to 
provide employers, employees, and other affected parties with 
additional information on techniques of complying with the OSHA rules. 
In fact, two notes in Sec. 1910.137 accept compliance with specific 
ASTM standards as being compliance with Sec. 1910.137. The Agency has 
reviewed the new ANSI and ASTM standards and has found them to provide 
newer, more technically up-to-date information than the older versions. 
Therefore, this correction notice is updating the references in 
Sec. 1910.137 and Sec. 1910.269 to the later ANSI and ASTM standards. 
In Sec. 1910.137, OSHA is retaining the slightly older editions of the 
ASTM standards, in addition to the more recent editions, to clarify 
that electrical protective equipment manufactured in accordance with 
the older standards is still acceptable.

PART 1910--[CORRECTED]
