                               EXPLANATION

    The Code of Federal Regulations is a codification of the general and 
permanent rules published in the Federal Register by the Executive 
departments and agencies of the Federal Government. The Code is divided 
into 50 titles which represent broad areas subject to Federal 
regulation. Each title is divided into chapters which usually bear the 
name of the issuing agency. Each chapter is further subdivided into 
parts covering specific regulatory areas.
    Each volume of the Code is revised at least once each calendar year 
and issued on a quarterly basis approximately as follows:

Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1

    The appropriate revision date is printed on the cover of each 
volume.

LEGAL STATUS

    The contents of the Federal Register are required to be judicially 
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie 
evidence of the text of the original documents (44 U.S.C. 1510).

HOW TO USE THE CODE OF FEDERAL REGULATIONS

    The Code of Federal Regulations is kept up to date by the individual 
issues of the Federal Register. These two publications must be used 
together to determine the latest version of any given rule.
    To determine whether a Code volume has been amended since its 
revision date (in this case, October 1, 2023), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request.

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These OMB numbers are 
placed as close as possible to the applicable recordkeeping or reporting 
requirements.

PAST PROVISIONS OF THE CODE

    Provisions of the Code that are no longer in force and effect as of 
the revision date stated on the cover of each volume are not carried. 
Code users may find the text of provisions in effect on any given date 
in the past by using the appropriate List of CFR Sections Affected 
(LSA). For the convenience of the reader, a ``List of CFR Sections 
Affected'' is published at the end of each CFR volume. For changes to 
the Code prior to the LSA listings at the end of the volume, consult 
previous annual editions of the LSA. For changes to the Code prior to 
2001, consult the List of CFR Sections Affected compilations, published 
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

``[RESERVED]'' TERMINOLOGY

    The term ``[Reserved]'' is used as a place holder within the Code of 
Federal Regulations. An agency may add regulatory information at a 
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used 
editorially to indicate that a portion of the CFR was left vacant and 
not dropped in error.

INCORPORATION BY REFERENCE

    What is incorporation by reference? Incorporation by reference was 
established by statute and allows Federal agencies to meet the 
requirement to publish regulations in the Federal Register by referring 
to materials already published elsewhere. For an incorporation to be 
valid, the Director of the Federal Register must approve it. The legal 
effect of incorporation by reference is that the material is treated as 
if it were published in full in the Federal Register (5 U.S.C. 552(a)). 
This material, like any other properly issued regulation, has the force 
of law.
    What is a proper incorporation by reference? The Director of the 
Federal Register will approve an incorporation by reference only when 
the requirements of 1 CFR part 51 are met. Some of the elements on which 
approval is based are:
    (a) The incorporation will substantially reduce the volume of 
material published in the Federal Register.
    (b) The matter incorporated is in fact available to the extent 
necessary to afford fairness and uniformity in the administrative 
process.
    (c) The incorporating document is drafted and submitted for 
publication in accordance with 1 CFR part 51.
    What if the material incorporated by reference cannot be found? If 
you have any problem locating or obtaining a copy of material listed as 
an approved incorporation by reference, please contact the agency that 
issued the regulation containing that incorporation. If, after 
contacting the agency, you find the material is not available, please 
notify the Director of the Federal Register, National Archives and 
Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, 
or call 202-741-6010.

CFR INDEXES AND TABULAR GUIDES

    A subject index to the Code of Federal Regulations is contained in a 
separate volume, revised annually as of January 1, entitled CFR Index 
and Finding Aids. This volume contains the Parallel Table of Authorities 
and Rules. A list of CFR titles, chapters, subchapters, and parts and an 
alphabetical list of agencies publishing in the CFR are also included in 
this volume.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

    The Federal Register Index is issued monthly in cumulative form. 
This index is based on a consolidation of the ``Contents'' entries in 
the daily Federal Register.
    A List of CFR Sections Affected (LSA) is published monthly, keyed to 
the revision dates of the 50 CFR titles.

REPUBLICATION OF MATERIAL

    There are no restrictions on the republication of material appearing 
in the Code of Federal Regulations.

                    Subpart 167.01_General Provisions



Sec.  167.01-1  Basis and purpose of part.

    The rules and regulations in this part are prescribed and apply to 
public nautical school ships, except vessels of the Navy or Coast Guard. 
It is the intent of the regulations in this part to provide minimum 
standards for vessels used as nautical school ships in accordance with 
the various inspection statutes and to obtain their correct and uniform 
application. This part is not applicable to civilian nautical school 
ships.

[CGD 95-028, 62 FR 51216, Sept. 30, 1997]



Sec.  167.01-5  Applicability; preemptive effect.

    (a) Regulations in this part contain requirements for the design, 
construction, inspection, lifesaving equipment,

[[Page 8]]

firefighting and fire prevention requirements, special operating 
requirements and number of persons allowed to be carried on nautical 
school ships. The regulations in this subchapter have preemptive effect 
over State or local regulations in the same field.
    (b) Vessels owned or chartered by the United States Maritime 
Administration that may be used by or in connection with any nautical 
school are not normally considered as merchant vessels of the United 
States and, therefore, are not documented.
    (c) Documented nautical school ships of 500 gross tons or more, on 
international voyages, shall comply with the standards of the 
International Convention for Safety of Life at Sea, 1974, for cargo 
vessels.
    (d) The regulations in this part have preemptive effect over State 
or local regulations in the same field.

coastwise routes shall be considered suitable for navigation insofar as 
the provisions of this subchapter are concerned on any inland route, 
including the Great Lakes.

[CGFR 59-10, 24 FR 3240, Apr. 25, 1959]



Sec.  167.01-8  Inspection of school ships using gross tonnage criterion.

    (a) One of the criteria used for invocation of safety standards is 
the descriptions of school ships by relative sizes in gross tonnages. 
When it is determined in accordance with Sec.  70.05-20 of this chapter 
that a particular school ship has a Bureau of Customs' assigned gross 
register tonnage which is not indicative of the relative physical size 
of the vessel, the requirements in this part and the manning shall be 
that applicable to a vessel of the greater relative size.

[CGFR 60-50, 25 FR 7982, Aug. 18, 1960]



Sec.  167.01-10  Effective date of regulations.

    (a) The regulations in this part shall be in effect on and after 
July 1, 1951: Provided, That amendments, revisions, or additions shall 
become effective 90 days after the date of publication in the Federal 
Register unless the Commandant shall fix a different time.
    (b) Amendments to regulations in this part will not be retroactive 
in effect unless specifically made so at the time the amendments are 
issued.



Sec.  167.01-15  Specifications for articles or materials.

    Articles of equipment or materials used in the equipment or the 
construction of vessels, which conform to the specifications of the Navy 
or Coast Guard or their approved equivalent, may be accepted.

assigned to information collection and recordkeeping requirements in 
this subchapter by the Office of Management and Budget (OMB) pursuant to 
the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et seq.). The Coast 
Guard intends that this section comply with the requirements of 44 
U.S.C. 3507(f), which requires that agencies display a current control 
number assigned by the Director of the OMB for each approved agency 
information collection requirement.
    (b) Display.

  Subpart 167.45_Special Firefighting and Fire Prevention Requirements



Sec.  167.45-1  Steam, carbon dioxide, Halon 1301, and clean agent 
fire extinguishing systems.

    (a) General requirements. (1) Nautical school ships shall be 
provided with an inert-gas fire-extinguishing system when required.
    (2) All nautical school ships carrying combustible cargo in the 
holds, between decks, or other closed cargo compartments shall be 
equipped with means for extinguishing fire in such compartments by the 
use of any inert-gas fire-extinguishing system approved by the Coast 
Guard or Navy. However, in specific cases where by reason of the design, 
such compartments are normally accessible and considered to be part of 
the working or living quarters,

[[Page 18]]

a water sprinkling system may be installed in lieu of an inert-gas fire-
extinguishing system. On such vessels contracted for prior to January 1, 
1962, a steam smothering system may be accepted in lieu of the inert gas 
system for the protection of cargo holds, paint lockers, and similar 
spaces. However, although existing steam smothering systems may be 
repaired, replaced, or extended, no new systems contracted for on or 
after January 1, 1962, will be permitted.
    (3) Cabinets, boxes, or casings enclosing manifolds or valves must 
be marked in conspicuous red letters at least 2 inches high: ``[STEAM/
CARBON DIOXIDE/HALON/CLEAN AGENT--as appropriate] FIRE APPARATUS.''.
    (4) Steam or gas piping fitted for extinguishing fire shall not be 
used for any other purpose except that it may be used for fire-detecting 
purposes.
    (5) Pipes for conveying steam from the boilers for the purpose of 
extinguishing fire shall not be led into the cabins, other living 
spaces, or working spaces. Pipes for conveying carbon dioxide or other 
extinguishing vapors for the purpose of extinguishing fire shall not be 
led into the cabins or other living spaces.
    (6) Steam smothering lines shall be tested with at least 50 pounds 
air pressure with ends of the smothering lines capped, or by blowing 
steam through the lines, and a survey made for detecting corrosion and 
defects, using the hammer test or such other means as may be necessary.
    (7) At annual inspections, each carbon dioxide cylinder, whether 
fixed or portable, each Halon 1301 cylinder, and each clean agent 
cylinder must be examined externally and replaced if excessive corrosion 
is found; and:
    (i) Each carbon dioxide cylinder must be weighed and recharged if 
its weight loss exceeds 10 percent of the charge;
    (ii) Each Halon 1301 and halocarbon cylinder must be weighed and 
checked, and recharged or replaced if weight loss exceeds 5 percent of 
required weight of charge or if cylinder pressure loss exceeds 10 
percent of specified gauge pressure, adjusted for temperature; and
    (iii) Each inert gas cylinder must be checked and recharged or 
replaced if cylinder pressure loss exceeds 5 percent of specified gauge 
pressure adjusted for temperature.
    (8) Carbon dioxide, Halon 1301, and clean agent cylinders carried on 
board nautical school ships must be tested and marked in accordance with 
the requirements of 46 CFR 147.60, 147.65, 147.66, and 147.67.
    (9) On all systems test time delays, alarms, and ventilation 
shutdowns with carbon dioxide, nitrogen, or other nonflammable gas as 
stated in the system manufacturer's instruction manual. Inspect hoses 
for damage or decay. Ensure that nozzles are unobstructed.
    (b) Steam systems. (1) As noted in subparagraph (a)(2) of this 
section, steam smothering systems are not permitted on nautical school 
ships contracted for on or after January 1, 1962, nor for new 
installations on vessels contracted for prior to that date. Where steam 
smothering systems are installed, the provisions of this paragraph shall 
be met.
    (2) Steam for fire-extinguishing systems shall be available at a 
suitable pressure from the main boilers or a donkey or auxiliary boiler.
    (3) The pipe lines shall be led from not more than three stations in 
easily accessible locations on the weather deck to each cargo hold, 
cargo 'tween-decks, or other closed cargo compartments, and to each 
cargo-oil deep tank, lamp locker, oil room, and like compartments, which 
lamp locker, oil room, and like compartments, shall be wholly and 
tightly lined with metal. The steam connections to the lamp lockers, oil 
rooms, and like compartments may be taken from the nearest steam supply 
line, independent of the extinguishing manifolds. In lamp lockers, oil 
rooms, and like compartments, adequate means may be provided for 
ventilation if suitable dampers capable of being operated from outside 
the spaces are fitted in each vent duct.
    (4) Each pipe in the extinguishing manifolds shall be fitted with a 
shut-off valve plainly and permanently marked to indicate into which 
compartment it discharges. This requirement also applies to independent 
extinguishing lines.
    (5) Manifold steam supply pipes shall be fitted with master valves 
at the manifolds, and provision shall be made

[[Page 19]]

for draining the manifold and individual lines to protect them against 
freezing. If the manifolds are located on an open deck, they shall be 
enclosed in a metal box.
    (6) The minimum diameter of any steam fire-extinguishing pipe to a 
cargo hold, cargo 'tween-decks, other closed cargo compartments, or 
cargo-oil deep tank shall be one inch, the size and number of pipes to 
be governed by the size of the compartment. The minimum diameter of any 
steam fire-extinguishing pipe to a lamp locker, oil room, or like 
compartments, shall be three-fourths of an inch.
    (c) Inert-gas systems. (1) When a carbon dioxide (CO2) 
smothering system is fitted in the cargo hold, cargo 'tween-decks, or 
other closed cargo compartments, or cargo-oil deep tanks, the quantity 
of carbon dioxide shall be sufficient to give a gas saturation of 30 
percent of the gross volume of the largest cargo hold. The quantity in 
pounds of carbon dioxide required may be determined approximately by the 
following formula:
[GRAPHIC] [TIFF OMITTED] TC01MR91.000

where:

W = the weight of CO2 required, in pounds.
L = the length of the hold, in feet.
B = the mean breadth of the hold, in feet,
D = the depth from tank top or flat forming lower boundary to top of 
          uppermost space in which freight may be carried, in feet.

    (2) When a carbon dioxide (CO2) smothering system is 
fitted in the lamp locker, oil room, or like compartments, the quantity 
in pounds of carbon dioxide required may be determined by dividing the 
gross volume of the space by a factor of 22. Lamp lockers, oil rooms, 
and like compartments, in all classes of vessels, shall be wholly and

Sec.  167.45-45  Carbon dioxide fire extinguishing system requirements.

    (a) When a carbon dioxide (CO2) smothering system is 
fitted in the boiler room, the quantity of carbon dioxide carried shall 
be sufficient to give a gas saturation of 25 percent of the gross volume 
of the largest boiler room from tank top to top of the boilers. Top of 
the boilers is to be considered as the top of the shell of a Scotch or 
leg type of boiler, and the top of the casing or drum, whichever is the 
higher, on water-tube boilers. The quantity of carbon dioxide required 
may be determined approximately by the following formula:
[GRAPHIC] [TIFF OMITTED] TC01MR91.001

where:

W = the weight of CO2 required in pounds.
L = the length of the boiler room in feet.
B = the breadth of the boiler room in feet.
D = the distance in feet from tank top or flat forming lower boundary to 
          top of boilers.

    (b) When a carbon dioxide (CO2) smothering system is 
fitted in the machinery space of a nautical school ship propelled by 
internal combustion engines, the quantity of carbon dioxide required may 
be determined approximately by the following formula:
[GRAPHIC] [TIFF OMITTED] TC01MR91.002

where:

W = the weight of CO2 required in pounds.
L = the length of machinery space in feet.
B = breadth of the machinery space in feet.
D = distance in feet from tank top or flat forming lower boundary to the 
          underside of deck forming the batch opening.

    (c) The whole charge of gas shall be capable of being released 
simultaneously by operating one valve and control. All cylinders shall 
be completely discharged in not more than two minutes. The arrangement 
of the piping shall be such as to give a general and fairly uniform 
distribution over the entire area protected. An alarm which shall 
operate automatically with the operation of the system shall be provided 
to give a warning in the space when the carbon dioxide is about to be 
released. Provision shall be made to prevent the admission of air into 
the lower parts of the boiler or engine room while the system is in 
operation.
    (d)(1) A lockout valve must be provided on any carbon dioxide 
extinguishing system protecting a space over 6,000 cubic feet in volume 
and installed or altered after July 9, 2013. ``Altered'' means modified 
or refurbished beyond the maintenance required by the manufacturer's 
design, installation, operation and maintenance manual.
    (2) The lockout valve must be a manually operated valve located in 
the discharge manifold prior to the stop valve or selector valves. When 
in the closed position, the lockout valve must provide complete 
isolation of the system from the protected space or spaces, making it 
impossible for carbon dioxide to discharge in the event of equipment 
failure during maintenance.
    (3) The lockout valve design or locking mechanism must make it 
obvious whether the valve is open or closed.
    (4) A valve is considered a lockout valve if it has a hasp or other 
means of attachment to which, or through which, a lock can be affixed, 
or it has a locking mechanism built into it.
    (5) The master or person-in-charge must ensure that the valve is 
locked open at all times, except while maintenance is being performed on 
the extinguishing system, when the valve must be locked in the closed 
position.
    (6) Lockout valves added to existing systems must be approved by the 
Commandant as part of the installed system.

[[Page 23]]

    (e) Each carbon dioxide extinguishing system installed or altered 
after [July 9, 2013, must have an approved odorizing unit to produce the 
scent of wintergreen, the detection of which will serve as an indication 
that carbon dioxide gas is present in a protected area and any other 
area into which the carbon dioxide may migrate. ``Altered'' means 
modified or refurbished beyond the maintenance required by the 
manufacturer's design, installation, operation and maintenance manual.

of corridor length or fraction thereof in the spaces occupied by 
passengers and crew.
    (3) In all public spaces fire extinguishers shall be located not 
more than 150 feet apart.
    (b) The number of required fire extinguishers is based on the 
capacity of the ordinary fire extinguisher, which is about 2\1/2\ 
gallons, and no fire extinguisher of larger capacity shall be allowed a 
greater rating than that of the ordinary fire extinguisher. Fire 
extinguishers of approved types of less capacity are allowable when 
their total contents equal the required quantity.



Sec.  167.45-70  Portable fire extinguishers, general requirements.

    (a) Extra charges shall be carried on board for 50 percent of each 
size and variety of fire extinguishers provided. If 50 percent of each 
size and variety of fire extinguishers carried gives a fractional 
result, extra charges shall be provided for the next largest whole 
number.
    (1) The following is an example:

 
        Fire extinguishers carried:            Extra charges required

spare charges for all such units of the same size and variety.
    (b) Recharges, particularly the acid, used in charging soda-and-acid 
type of fire extinguishers, shall be packed in such manner that the 
filling operation (i.e., in recharging the extinguisher) can be 
performed without subjecting the person doing the recharging to undue 
risk of acid burns and shall be contained in Crown stopper type of 
bottle.
    (c) [Reserved]
    (d) Fire extinguishers shall be located in such places as in the 
judgment of the Officer in Charge, Marine Inspection, will be most 
convenient and serviceable in case of emergency and so arranged that 
they may be easily removed from their fastenings.
    (e) Every fire extinguisher provided shall be examined at each 
annual inspection to determine that it is still in good condition. Soda-
and-acid and foam fire extinguishers shall be tested by discharging the 
contents, cleaning thoroughly, and then refilling. Carbon dioxide fire 
extinguishers shall be checked by weighing to determine contents and if 
found to be more than 10 percent under required contents of carbon 
dioxide shall be recharged. Pump tank fire extinguishers shall be tested 
by pumping and discharging the contents, cleaning thoroughly, and then 
refilling or recharging. Cartridge-operated type fire extinguishers 
shall be checked by examining the extinguishing agents to determine if 
in still good condition and by examining the pressure cartridge. If the 
cartridge end is punctured, or it the cartridge is otherwise determined 
to have leaked or to be in an unsuitable condition, the pressure 
cartridge shall be rejected and a new one inserted. Stored pressure type 
extinguishers shall be checked by determining that the pressure gage is 
in the operating range, and the full charge of extinguishing agent is in 
the chamber. The hoses and nozzles of all fire extinguishers shall be 
inspected to see that they are clear and in good condition.

    (c) If your vessel is 15 years old or older, the cognizant District 
Commander, on a case-by-case basis, may approve an underwater survey 
instead of a drydock examination at alternating intervals. You must 
submit an application for an underwater survey to the OCMI at least 90 
days before your vessel's next required drydock examination. You may be 
allowed this option if--
    (1) The vessel is qualified under paragraphs (a)(2) through (4) of 
this section;
    (2) Your application includes the information in paragraphs (b)(1) 
through (b)(7) of this section; and

    (1) Righting arm or moment curves.
    (2) Heeling arm or moment curves.
    (3) Cross curves of stability.
    (4) Floodable length curves.
    (c) The assumed weight per person for calculations showing 
compliance with the regulations of this subchapter must be 
representative of the passengers and crew aboard the vessel while 
engaged in the service intended. Unless the Officer in Charge, Marine 
Inspection (OCMI) permits or requires the use of other values in 
writing, the assumed weight per person of passengers and crew must not 
be less than that the Assumed Average Weight per Person (AAWPP) 
calculated in accordance with paragraphs (d) and (e) of this section.
    (d)(1) The AAWPP is 185 lb from December 1, 2011 until the AAWPP is 
first updated pursuant to the provisions of this section. As of the 
effective date of the first AAWPP update after December 1, 2011, this 
paragraph (d)(1) will be superseded and cease to be effective.
    (2) The formula in paragraph (e) of this section will be used to 
determine an update to the AAWPP. It requires the use of data in the 
most recent report released by the Centers for Disease Control and 
Prevention (CDC) through the National Center for Health Statistics 
(NCHS), or any successors to those centers. This report can be found on 
the CDC's Web site.
    (3) Each time the CDC releases a report containing mean weights of 
United States adult males and females, the Coast Guard will apply the 
formula in paragraph (e) of this section to that data. The resulting 
value will become the new AAWPP only if the sum equals or exceeds 10 
pounds more than the AAWPP then in effect. The Coast Guard will notify 
the public of the new AAWPP in the Federal Register and other 
appropriate media.
    (4) Updates to the AAWPP used in calculations showing compliance 
with this subchapter will be promulgated as interpretive rules and 
become effective in accordance with the provisions of this section 
without further rulemaking procedures.
    (5) Notwithstanding any other provisions of this section, the Coast 
Guard may choose, in its discretion, to conduct further rulemaking

Where--

P = .005 + (L/14,200)\2\ tons/ft\2\ . . . for ocean service, Great Lakes 
          winter service, or service on exposed waters.
P = .055 + (L/1309)\2\ metric tons/m\2\ . . . for ocean service, Great 
          Lakes winter service, or service on exposed waters.
P = .0033 + (L/14,200)\2\ tons/ft\2\ . . . for Great Lakes summer 
          service or service on partially protected waters.
P = .036 + (L/1309)\2\ metric tons/m\2\ . . . for Great lakes summer 
          service or service on partially protected waters.

          waters.
P = .028 + (L/1309)\2\ metric tons/m\2\ . . . for service on protected 
          waters.
L = LBP in feet (meters).
A = projected lateral area in square feet (square meters) of the portion 
          of the vessel and deck cargo above the waterline.
H = the vertical distance in feet (meters) from the center of A to the 
          center of the underwater lateral area or approximately to the 
          one-half draft point.
W = displacement in long (metric) tons.
T = either:
    (1) the lesser of either 14 degrees heel or the angle of heel in 
degrees at which one-half the freeboard to the deck edge is immersed; or
    (2) for a sailing vessel, T = the lesser of either 14 degrees or the 
angle of heel in degrees to the deck edge.
    The deck edge is to be taken as the intersection of the sideshell 
and the uppermost continuous deck below which the sideshell is 
weathertight.

    (b) If approved by the Coast Guard Marine Safety Center or the ABS, 
a larger value of T may be used for a vessel with a discontinuous 
weather deck or abnormal sheer.
    (c) When doing the calculations required by paragraph (a) of this 
section for a sailing vessel or auxiliary sailing vessel, the vessel 
must be assumed--
    (1) To be under bare poles; or
    (2) If the vessel has no auxiliary propulsion, to have storm sails

(GZ) at the angle (T), calculated after the vessel is permitted to trim 
free until the trimming moment is zero, is not less than the minimum 
metacentric height (GM) calculated in paragraph (a) of this section 
multiplied by sin(T). On other types of vessels, the Coast Guard Marine 
Safety Center requires calculations in addition to those in paragraph 
(a) of this section. On a mechanically powered vessel under 328 feet 
(100 meters) in length, other than a tugboat or a towboat, the 
requirements in Sec.  170.173 are applied.

    (d) Installations of sliding watertight door assemblies must be in 
accordance with the following:
    (1) Before a sliding watertight door assembly is installed in a 
vessel, the bulkhead in the vicinity of the door opening must be 
stiffened. Such bulkhead stiffeners, or deck reinforcement where flush 
deck door openings are desired, must not be less than 6 inches nor more 
than 12 inches from the door frame so that an unstiffened diaphragm of 
bulkhead plating 6 to 12 inches wide is provided completely around the 
door frame. Where such limits cannot be maintained, alternative 
installations will be considered by the Marine Safety Center. In 
determining the scantlings of these bulkhead stiffeners, the door frame 
should not be considered as contributing to the strength of the 
bulkhead. Provision must also be made to adequately support the thrust 
bearings and other equipment that may be mounted on the bulkhead or 
deck.
    (2) Sliding watertight door frames must be either bolted or welded 
watertight to the bulkhead.
    (i) If bolted, a suitable thin heat and fire resistant gasket or 
suitable compound must be used between the bulkhead and the frame for 
watertightness. The bulkhead plating must be worked to a plane surface 
in way of the frame when mounting.
    (ii) If welded, caution must be exercised in the welding process so 
that the door frame is not distorted.
    (e) For each watertight door which is in a required subdivision 
bulkhead, an indicator light must be installed in the pilothouse and at 
each other vessel operating station from which the door is not visible. 
The indicator must show whether the door is open or closed.

liquid in the tank.
    (b) The virtual rise in the vertical center of gravity calculated in 
accordance with Sec.  170.285(a) for a stabilization tank may be reduced 
in accordance with the following equation:

E.F.S. = (K)(F.F.S.)

where--

E.F.S. = the effective free surface.
F.F.S. = the full free surface calculated in accordance with Sec.

tank;
    (ii) (d) is the density of the liquid in the roll tank; and
    (iii) (T) is the angle of heel.
    (2) Plot the moments of transference of the liquid in the roll tank 
on Graph 170.295.
    (3) Construct a line A on Graph 170.295 so that the area under line 
A between T = 0 and the angle at which the deck edge is immersed or 28 
degrees, whichever is smaller, is equal to the area under the curve of 
actual moments of transference between the same angles.
    (4) The factor (K) is calculated by determining the ratio of the 
ordinate of line A to the ordinate of the curve of (I/d)tan T, both 
measured at the angle at which the deck edge is immersed or 28 degrees, 
whichever is smaller.

Sec.  171.066  Calculation of permeability for Type I subdivision.

    (a) Except as prescribed in paragraph (b) of this section, the 
following permeabilities must be used when doing the calculations 
required to demonstrate compliance with Sec.  171.065(a), (b), and (c):
    (1) When doing calculations required to demonstrate compliance with 
Sec.  171.065(a) and (b), the uniform average permeability given by the 
formulas in Table 171.066 must be used.
    (2) When doing calculations required to demonstrate that 
compartments on opposite sides of a main transverse watertight bulkhead 
that bounds the machinery space comply with Sec.  171.065(c), the mean 
of the uniform average permeabilities determined from Table 171.066 for 
the two compartments must be used.
    (b) If an average permeability can be calculated that is less than 
that given by the formulas in Table 171.066, the lesser value may be 
substituted if approved by the Commanding Officer, Marine Safety Center. 
When determining this lesser value, the following permeabilities must be 
used:
    (1) 95% for passenger, crew, and all other spaces that, in the full 
load condition, normally contain no cargo, stores, provisions, or mail.
    (2) 60% for cargo, stores, provisions, or mail spaces.
    (3) 85% for spaces containing machinery.
    (4) Values approved by the Commanding Officer, Marine Safety Center 
for double bottoms, oil fuel, and other tanks.
    (c) In the case of unusual arrangements, the Commanding Officer, 
Marine Safety Center may require a detailed calculation of average 
permeability for the portions of the vessel forward or aft of the 
machinery spaces. When doing these calculations, the permeabilities 
specified in paragraph (b) of this section must be used.
    (d) When calculating permeability, the total volume of the `tween 
deck spaces between two adjacent main transverse watertight bulkheads 
that contains any passenger or crew space must be regarded as passenger 
space volume, except that the volume of any space that is completely 
enclosed in steel bulkheads and is not a crew or passenger space may be 
excluded.

Sec.  171.067  Treatment of stepped and recessed bulkheads in Type I subdivision.

    (a) For the purpose of this section--
    (1) The main transverse watertight bulkhead immediately forward of a 
stepped bulkhead is referred to as bulkhead 1; and
    (2) The main transverse watertight bulkhead immediately aft of the 
stepped bulkhead is referred to as bulkhead 3.
    (b) If a main transverse watertight bulkhead is stepped, it and 
bulkheads 1 and 3 must meet one of the following conditions:
    (1) The separation between bulkheads 1 and 3 must not exceed the 
following:
    (i) If the factor of subdivision (FS) determined from Sec.  171.065 
(a) or (b) is greater than 0.9, the distance between bulkheads 1 and 3 
must not exceed the maximum separation calculated to demonstrate 
compliance with Sec.  171.065.
    (ii) If the factor of subdivision is 0.9 or less, the distance 
between bulkheads 1 and 3 must not exceed 90% of the floodable length or 
twice the maximum bulkhead separation calculated to demonstrate 
compliance with Sec.  171.065, whichever is smaller.
    (2) Additional watertight bulkheads must be located as shown in 
Figure 171.067(a) so that distances A, B, C, and D, illustrated in 
Figure 171.067(a), satisfy the following:
    (i) Distances A and B must not exceed the maximum spacing allowed by 
Sec.  171.065.
    (ii) Distances C and D must not be less than the minimum separation 
prescribed by Sec.  171.065(e).
    (3) The distance A, illustrated in Figure 171.067(b), must not 
exceed the maximum length determined in Sec.  171.065 corresponding to a 
margin line taken 3 inches (7.6 cm) below the step.
    (c) A main transverse bulkhead may not be recessed unless all parts 
of the recess are inboard from the shell of the vessel a distance A as 
illustrated in Figure 171.067(c).
    (d) Any part of a recess that lies outside the limits defined in 
paragraph (c) of this section must be treated as a step in accordance 
with paragraph (b) of this section.
    (e) The distance between a main transverse watertight bulkhead and 
the transverse plane passing through the nearest portion of a recessed 
bulkhead must be greater than the minimum separation specified by Sec.  
171.065(e).
    (f) If a main transverse bulkhead is stepped or recessed, equivalent 
plane bulkheads must be used in the calculations required to demonstrate 
compliance with Sec.  171.065.

Sec.  171.068  Special considerations for Type I subdivision for vessels
on short international voyages.

    (a) The calculations done to demonstrate compliance with Sec.  
171.065 for a vessel that makes short international voyages and is 
permitted under Sec.  75.10-10 of this chapter to carry a number of 
persons on board in excess of the lifeboat capacity must--
    (1) Assume the uniform average permeabilities given in Table 171.068 
in lieu of those in Table 171.066; and
    (2) Use a factor of subdivision (FS) that is the smaller of the 
following:
    (i) The value from Table 171.065(a).
    (ii) 0.50.

[[Page 122]]

    (b) For a vessel less than 300 feet (91 meters) in length, the 
Commanding Officer, Marine Safety Center may approve the separation of 
main transverse watertight bulkheads greater than that permitted by 
paragraph (a) of this section if--
    (1) The shorter separation is impracticable; and
    (2) The separation is the smallest that is practicable.
    (c) In the case of ships less than 180 feet (55 meters) in length, 
the Commanding Officer, Marine Safety Center may approve a further 
relaxation in the bulkhead spacing. However, in no case may the 
separation be large enough to prevent the vessel from complying with the 
flooding requirements for Type II subdivision in Sec.  171.070.

Sec.  171.075  [Reserved]



Sec.  171.080  Damage stability standards for vessels with Type I or
Type II subdivision.

    (a) Calculations. Each vessel with Type I or Type II subdivision 
must be shown by design calculations to meet the survival conditions in 
paragraph (e), (f), or (g) of this section in each condition of loading 
and operation assuming the extent and character of

[[Page 124]]

damage specified in paragraph (b) of this section.
    (b) Extent and character of damage. For the purpose of paragraph (a) 
of this section, design calculations must assume that the damage--
    (1) Has the character specified in Table 171.080(a); and
    (2) Consists of a penetration having the dimensions specified in 
Table 171.080(a) except that, if the most disabling penetration would be 
less than the penetration described in the table, the smaller 
penetration must be assumed.
    (c) Permeability. When doing the calculations required in paragraph 
(a) of this section, the permeability of each space must be calculated 
in a manner approved by the Commanding Officer, Marine Safety Center or 
be taken from Table 171.080(c).
    (d) Definitions. For the purposes of paragraphs (e) and (f) of this 
section, the following definitions apply:
    (1) New vessel means a vessel--
    (i) For which a building contract is placed on or after April 15, 
1996;
    (ii) In the absence of a building contract, the keel of which is 
laid, or which is at a similar stage of construction, on or after April 
15, 1996;
    (iii) The delivery of which occurs on or after January 1, 1997;
    (iv) Application for the reflagging of which is made on or after 
January 1, 1997; or
    (v) That has undergone--
    (A) A major conversion for which the conversion contract is placed 
on or after April 15, 1996;
    (B) In the absence of a contract, a major conversion begun on or 
after April 15, 1996; or
    (C) A major conversion completed on or after January 1, 1997.
    (2) Existing vessel means other than a new vessel.
    (3) Watertight means capable of preventing the passage of water 
through the structure in any direction under a head of water for which 
the surrounding structure is designed.
    (4) Weathertight means capable of preventing the penetration of 
water, even boarding seas, into the vessel in any sea condition.
    (e) Damage survival for all existing vessels except those vessels 
authorized to carry more than 12 passengers on an international voyage 
requiring a SOLAS Passenger Ship Safety Certificate. An existing vessel 
is presumed to survive assumed damage if it meets the following 
conditions in the final stage of flooding:
    (1) On a vessel required to survive assumed damage with a 
longitudinal extent of 10 feet (3 meters) plus 0.03L, the final angle of 
equilibrium must not exceed 7 degrees after equalization, except that 
the final angle may be as large as 15 degrees if--
    (i) The vessel is not equipped with equalization or is equipped with 
fully automatic equalization; and
    (ii) The Commanding Officer, Marine Safety Center approves the 
vessel's range of stability in the damaged condition.
    (2) On a vessel required to survive assumed damage with a 
longitudinal extent of 20 feet (6.1 meters) plus 0.04L, the angle of 
equilibrium must not exceed 15 degrees after equalization.
    (3) The margin line may not be submerged at any point.
    (4) The vessel's metacentric height (GM) must be at least 2 inches 
(5 cm) when the vessel is in the upright position.
    (f) Damage survival for all new vessels except those vessels 
authorized to carry more than 12 passengers on an international voyage 
requiring a SOLAS Passenger Ship Safety Certificate. A new vessel is 
presumed to survive assumed damage if it is shown by calculations to 
meet the conditions set forth in paragraphs (f) (1) through (7) of this 
section in the final stage of flooding and to meet the conditions set 
forth in paragraphs (f) (8) and (9) of this section in each intermediate 
stage of flooding. For the purposes of establishing boundaries to 
determine compliance with the requirements in paragraphs (f) (1) through 
(9), openings that are fitted with weathertight closures and that are 
not submerged during any stage of flooding will not be considered 
downflooding points.
    (1) Each vessel must have positive righting arms for a minimum range 
beyond the angle of equilibrium as follows:

[[Page 125]]

Partially protected waters or Great Lakes summer.............         10
Protected waters.............................................          5
------------------------------------------------------------------------

    (2) No vessel may have any opening through which downflooding can 
occur within the minimum range specified by paragraph (f)(1) of this 
section.
    (3) Each vessel must have an area under each righting-arm curve of 
at least 0.015 meter-radians, measured from the angle of equilibrium to 
the smaller of the following angles:
    (i) The angle at which downflooding occurs.
    (ii) The angle of vanishing stability.
    (4) Except as provided by paragraph (f)(5) of this section, each 
vessel must have within the positive range the greater of a righting arm 
(GZ) equal to or greater than 0.10 meter or a GZ as calculated using the 
formula:
[GRAPHIC] [TIFF OMITTED] TR17OC95.004

where--

C = 1.00 for vessels on exposed waters, oceans, or Great Lakes winter;
C = 0.75 for vessels on partially protected waters or Great Lakes 
          summer;
C = 0.50 for vessels on protected waters;
[Delta] = intact displacement; and
Heeling moment = greatest of the heeling moments as calculated in 
          paragraphs (f)(4) (i) through (iv) of this section.

    (i) The passenger heeling moment is calculated using the formula:

Passenger Heeling Moment = 0.5 (n w b)

where--

n = number of passengers;
w = passenger weight used for calculations as determined in accordance 
          with Sec.  170.090(c) of this chapter; and
b = distance from the centerline of the vessel to the geometric center 
          on one side of the centerline of the passenger deck used to 
          leave the vessel in case of flooding.

    (ii) The heeling moment due to asymmetric escape routes for 
passengers, if the vessel has asymmetric escape routes for passengers, 
is calculated assuming that--
    (A) The weight of each passenger is the weight used for calculations 
as determined in accordance with Sec.  170.090(c) of this chapter;
    (B) Each passenger occupies 0.25 square meter of deck area; and
    (C) All passengers are distributed, on available deck areas 
unoccupied by permanently affixed objects, toward one side of the vessel 
on the decks where passengers would move to escape from the vessel in 
case of flooding, so that they produce the most adverse heeling moment.
    (iii) The heeling moment due to the launching of survival craft is 
calculated assuming that--
    (A) All survival craft, including davit-launched liferafts and 
rescue boats, fitted on the side to which the vessel heels after 
sustained damage, are swung out if necessary, fully loaded and ready for 
lowering;
    (B) Persons not in the survival craft swung out and ready for 
lowering are distributed about the centerline of the vessel so that they 
do not provide additional heeling or righting moments; and
    (C) Survival craft on the side of the vessel opposite that to which 
the vessel heels remain stowed.
    (iv) The heeling moment due to wind pressure is calculated assuming 
that--
    (A) The wind exerts a pressure of 120 Newtons per square meter;
    (B) The wind acts on an area equal to the projected lateral area of 
the vessel above the waterline corresponding to the intact condition; 
and
    (C) The lever arm of the wind is the vertical distance from a point 
at one-half the mean draft, or the center of area below the waterline, 
to the center of the lateral area.
    (5) Each vessel whose arrangements do not generally allow port or 
starboard egress may be exempted, by the Commanding Officer, Marine 
Safety Center, from the transverse passenger heeling moment required by 
paragraph (f)(4)(i) of this section. Each vessel exempted must have 
sufficient longitudinal stability to prevent immersion of the deck edge 
during forward or aft egress.
    (6) Each vessel must have an angle of equilibrium that does not 
exceed--
    (i) 7 degrees for flooding of one compartment;
    (ii) 12 degrees for flooding of two compartments; or

[[Page 126]]

    (iii) A maximum of 15 degrees for flooding of one or two 
compartments where--
    (A) The vessel has positive righting arms for at least 20 degrees 
beyond the angle of equilibrium; and
    (B) The vessel has an area under each righting-arm curve, when the 
equilibrium angle is between 7 degrees and 15 degrees, in accordance 
with the formula:

    A=0.0025([thetas]-1)

where--

A = Area required in m-rad under each righting-arm curve measured from 
          the angle of equilibrium to the smaller of either the angle at 
          which downflooding occurs or the angle of vanishing stability.
[thetas] = actual angle of equilibrium in degrees

    (7) The margin line of the vessel must not be submerged when the 
vessel is in equilibrium.
    (8) Each vessel must have a maximum angle of equilibrium that does 
not exceed 15 degrees during intermediate stages of flooding.
    (9) Each vessel must have a range of stability and a maximum 
righting arm during each intermediate stage of flooding as follows:

when meeting the requirements of this paragraph.
    (g) Damage survival for vessels constructed before January 1 2009 
authorized to carry more than 12 passengers on an international voyage 
requiring a SOLAS Passenger Ship Safety Certificate. A vessel is 
presumed to survive assumed damage if it is shown by calculations to 
comply with the damage stability required for that vessel by the 
International Convention for the Safety of Life at Sea, 1974, as 
amended, the applicable regulations of IMO Res. MSC.216(82) 
(incorporated by reference, see Sec.  171.012).
    (h) Equalization. (1) Equalization systems on vessels of 150 gross 
tons or more in ocean service must meet the following:
    (i) Equalization must be automatic except that the Commanding 
Officer, Marine Safety Center may approve other means of equalization 
if--
    (A) It is impracticable to make equalization automatic; and
    (B) Controls to cross-flooding equipment are located above the 
bulkhead deck.
    (ii) Equalization must be fully accomplished within 15 minutes after 
damage occurs.
    (2) Equalization on vessels under 150 gross tons in ocean service 
and on all vessels in other than ocean service must meet the following:
    (i) Equalization must not depend on the operation of valves.
    (ii) Equalization must be fully accomplished within 15 minutes after 
damage occurs.
    (3) The estimated maximum angle of heel before equalization must be 
approved by the Commanding Officer, Marine Safety Center.

Sec.  172.030  Exemptions for certain vessels.

    (a) Vessels are exempt from 172.015 on voyages between:
    (1) United States ports along the East Coast as far south as Cape 
Henry, VA;
    (2) Wilmington, NC and Miami, FL;
    (3) United States ports in the Gulf of Mexico;
    (4) Puget Sound ports and Canadian west coast ports or Columbia 
River ports, or both;
    (5) San Francisco, Los Angeles, and San Diego, CA.
    (b) Vessels exempt by paragraph (a) of this section must comply with 
the following conditions:
    (1) The master is satisfied that the vessel's longitudinal strength 
is not impaired.
    (2) The master ascertains the weather to be encountered on the 
voyage.
    (3) Potential heeling moments are reduced to a minimum by carrying 
as few slack holds as possible.
    (4) Each slack surface must be leveled.
    (5) The transverse metacentric height (GM), in meters, of the vessel 
throughout the voyage, after correction for liquid free surface, has 
been shown by stability calculations to be in excess of the required GM 
(GMR), in meters.
    (i) The GMR is the sum of the increments of GM (GMI) multiplied by 
the correction factor, f and r.

Where:

r = (available freeboard) (beam) of the vessel and
f = 1 if r is 0.268 or
f = (0.268 r) if r is <0.268.

    (ii) The GMI for each compartment which has a slack surface of 
grain, i.e., is not trimmed full, is calculated by the following 
formula:

GMI = (B3 x L x 0.0661)(Disp. x SF))

where:

B = breadth of slack grain surface (m
L = Length of compartment (m)
Disp. = Displacement of vessel (tons)
SF = Stowage factor of grain in compartment (cubic meters/tons)

    (c) Vessels which do not have the Document of Authorization required 
by Sec.  172.015 may carry grain in bulk up to one third of their 
deadweight tonnage provided the stability complies with the requirements 
of Section 9 of the International Code for the Safe Carriage of Grain in 
Bulk.



Sec.  172.040  Certificate of loading.

    (a) Before it sails, each vessel that loads grain in bulk, except 
vessels engaged solely on voyages on the Great Lakes, rivers, or lakes, 
bays, and sounds, must have a certificate of loading issued by an 
organization recognized by the Commandant for that purpose. The 
certificate of loading may be accepted as prima facie evidence of 
compliance with the regulations in this subpart.
    (b) The Commandant recognizes the National Cargo Bureau, Inc., 180 
Maiden Lane, Suite 903, New York, NY 10038, for the purpose of issuing 
certificates of loading.

relating to that Convention.

[USCG-2000-7641, 66 FR 55574, Nov. 2, 2001]



Sec.  172.050  Damage stability.

    (a) Each tank barge is assigned a hull type number by the Commandant 
in accordance with Sec.  32.63-5 of this chapter. The requirements in 
this section are specified according to the hull type number assigned.
    (b) Except as provided in paragraph (c) of this section, each Type I 
and II barge hull must have a watertight weather deck.
    (c) If a Type I or II barge hull has an open hopper, the fully 
loaded barge must be shown by design calculations to have at least 2 
inches (50mm) of positive GM when the hopper space is flooded to the 
height of the weather deck.
    (d) When demonstrating compliance with paragraph (c) of this 
section, credit may be given for the buoyancy of the immersed portion of 
cargo tanks if the tank securing devices are shown by design 
calculations to be strong enough to hold the tanks in place when they 
are subjected to the buoyant forces resulting from the water in the 
hopper.
    (e) Each tank barge must be shown by design calculations to have at 
least 2 inches (50 mm) of positive GM in each condition of loading and 
operation after assuming the damage specified in paragraph (f) of this 
section is applied in the following locations:
    (1) Type I barge hull not in an integrated tow. If a Type I hull is 
required and the barge is not a box barge designed for use in an 
integrated tow, design calculations must show that the barge hull can 
survive damage at any location including on the intersection of a 
transverse and longitudinal watertight bulkhead.
    (2) Type I barge hull in an integrated tow. If a Type I hull is 
required and the barge is a box barge designed for operation in an 
integrated tow, design calculations must show that the barge can survive 
damage--
    (i) To any location on the bottom of the tank barge except on a 
transverse watertight bulkhead; and
    (ii) To any location on the side of the tank barge including on a 
transverse watertight bulkhead.
    (3) Type II hull. If a Type II hull is required, design calculations 
must show that the barge can survive damage to any location except to a 
transverse watertight bulkhead.
    (f) For the purpose of paragraph (e) of this section--
    (1) Design calculations must include both side and bottom damage, 
applied separately; and
    (2) Damage must consist of the most disabling penetration up to and 
including penetrations having the following dimensions:
    (i) Side damage must be assumed to be as follows:
    (A) Longitudinal extent--6 feet (183 centimeters).
    (B) Transverse extent--30 inches (76 centimeters).
    (C) Vertical extent--from the baseline upward without limit.
    (ii) Bottom damage must be assumed to be 15 inches (38.1 
centimeters) from the baseline upward.



  Subpart D_Special Rules Pertaining to a Vessel That Carries a Cargo 
                     Regulated Under 33 CFR Part 157



Sec.  172.060  Specific applicability.

    This subpart applies to each U.S. tank vessel that is required to 
comply with 33 CFR 157.21.

[CGD 90-051, 57 FR 36246, Aug. 12, 1992]



Sec.  172.065  Damage stability.

    (a) Definitions. As used in this section, Length or L means load 
line length (LLL).
    (b) Calculations. Each tank vessel must be shown by design 
calculations to meet the survival conditions in paragraph (g) of this 
section in each condition of loading and operation except as specified 
in paragraph (c) of this section, assuming the damage specified in 
paragraph (d) of this section.
    (c) Conditions of loading and operation. The design calculations 
required by paragraph (b) of this section need not be done for ballast 
conditions if the

[[Page 140]]

vessel is not carrying oil, other than oily residues, in cargo tanks.
    (d) Character of damage. (1) If a tank vessel is longer than 738 
feet (225 meters) in length, design calculations must show that it can 
survive damage at any location.
    (2) If a tank vessel is longer than 492 feet (150 meters) in length, 
but not longer than 738 feet (225 meters), design calculations must show 
that it can survive damage at any location except the transverse 
bulkheads bounding an aft machinery space. The machinery space is 
calculated as a single floodable compartment.
    (3) If a tank vessel is 492 feet (150 meters) or less in length, 
design calculations must show that it can survive damage--
    (i) At any location between adjacent main transverse watertight 
bulkheads except to an aft machinery space;
    (ii) To a main transverse watertight bulkhead spaced closer than the 
longitudinal extent of collision penetration specified in Table 
172.065(a) from another main transverse watertight bulkhead; and
    (iii) To a main transverse watertight bulkhead or a transverse 
watertight bulkhead bounding a side tank or double bottom tank if there 
is a step or a recess in the transverse bulkhead that is longer than 10 
feet (3.05 meters) and that is located within the extent of penetration 
of assumed damage. The step formed by the after peak bulkhead and after 
peak tank top is not a step for the purpose of this regulation.
    (e) Extent of damage. For the purpose of paragraph (b) of this 
section--
    (1) Design calculations must include both side and bottom damage, 
applied separately; and
    (2) Damage must consist of the penetrations having the dimensions 
given in Table 172.065(a) except that, if the most disabling 
penetrations would be less than the penetrations described in this 
paragraph, the smaller penetration must be assumed.
    (f) Permeability of spaces. When doing the calculations required in 
paragraph (b) of this section--
    (1) The permeability of a floodable space, other than a machinery 
space, must be as listed in Table 172.065(b);
    (2) Calculations in which a machinery space is treated as a 
floodable space must be based on an assumed machinery space permeability 
of 85%, unless the use of an assumed permeability of less than 85% is 
justified in detail; and
    (3) If a cargo tank would be penetrated under the assumed damage, 
the cargo tank must be assumed to lose all cargo and refill with salt 
water, or fresh water if the vessel operates solely on the Great Lakes, 
up to the level of the tank vessel's final equilibrium waterline.
    (g) Survival conditions. A vessel is presumed to survive assumed 
damage if it meets the following conditions in the final stage of 
flooding:
    (1) Final waterline. The final waterline, in the final condition of 
sinkage, heel, and trim, must be below the lower edge of an opening 
through which progressive flooding may take place, such as an air pipe, 
or an opening that is closed by means of a weathertight door or hatch 
cover. This opening does not include an opening closed by a--
    (i) Watertight manhole cover;
    (ii) Flush scuttle;
    (iii) Small watertight cargo tank hatch cover that maintains the 
high integrity of the deck;
    (iv) Class 1 door in a watertight bulkhead within the 
superstructure;
    (v) Remotely operated sliding watertight door; or
    (vi) Side scuttle of the non-opening type.
    (2) Heel angle. The maximum angle of heel must not exceed 25 
degrees, except that this angle may be increased to 30 degrees if no 
deck edge immersion occurs.
    (3) Range of stability. Through an angle of 20 degrees beyond its 
position of equilibrium after flooding, a tank vessel must meet the 
following conditions:
    (i) The righting arm curve must be positive.
    (ii) The maximum righting arm must be at least 3.94 inches (10 cm).
    (iii) Each submerged opening must be weathertight.
    (4) Progressive flooding. Pipes, ducts or tunnels within the assumed 
extent of damage must be either--

[[Page 141]]

    (i) Equipped with arrangements such as stop check valves to prevent 
progressive flooding to other spaces with which they connect; or
    (ii) Assumed in the design calculations required in paragraph (b) of 
this section to permit progressive flooding to the spaces with which 
they connect.
    (h) Buoyancy of superstructure. For the purpose of paragraph (b) of 
this section, the buoyancy of any superstructure directly above the side 
damage is to be disregarded. The unflooded parts of superstructures 
beyond the extent of damage may be taken into consideration if they are 
separated from the damaged space by watertight bulkheads and no 
progressive flooding of these intact spaces takes place.

Sec.  172.135  Extent of damage.

    For the purpose of Sec.  172.133--
    (a) Design calculations must include both side and bottom damage, 
applied separately; and
    (b) Damage must consist of the penetrations having the dimensions

Sec.  172.140  Permeability of spaces.

    (a) When doing the calculations required in Sec.  172.130, the 
permeability of a floodable space other than a machinery space must be 
as listed in Table 172.060(b).

[[Page 145]]

    (b) Calculations in which a machinery space is treated as a 
floodable space must be based on an assumed machinery space permeability 
of 0.85, unless the use of an assumed permeability of less than 0.85 is 
justified in detail.
    (c) If a cargo tank would be penetrated under the assumed damage, 
the cargo tank must be assumed to lose all cargo and refill with salt 
water up to the level of the tankship's final equilibrium waterline.



Sec.  172.150  Survival conditions.

    A tankship is presumed to survive assumed damage if it meets the 
following conditions in the final stage of flooding:
    (a) Final waterline. The final waterline, in the final condition of 
sinkage, heel, and trim, must be below the lower edge of openings such 
as air pipes and openings closed by weathertight doors or hatch covers. 
The following types of openings may be submerged when the tankship is at 
the final waterline:
    (1) Openings covered by watertight manhole covers or watertight 
flush scuttles.
    (2) Small watertight cargo tank hatch covers.
    (3) A Class 1 door in a watertight bulkhead within the 
superstructure.
    (4) Remotely operated sliding watertight doors.
    (5) Side scuttles of the non-opening type.
    (b) Heel angle. (1) Except as described in paragraph (b)(2) of this 
section, the maximum angle of heel must not exceed 15 degrees (17 
degrees if no part of the freeboard deck is immersed).
    (2) The Commanding Officer, Marine Safety Center will consider on a 
case by case basis each vessel 492 feet (150 meters) or less in length 
having a final heel angle greater than 17 degrees but less than 25 
degrees.
    (c) Range of stability. Through an angle of 20 degrees beyond its 
position of equilibrium after flooding, a tankship must meet the 
following conditions:
    (1) The righting arm curve must be positive.
    (2) The maximum righting arm must be at least 3.95 inches (10 cm).
    (3) Each submerged opening must be weathertight.
    (d) Progressive flooding. Pipes, ducts or tunnels within the assumed 
extent of damage must be either--
    (1) Equipped with arrangements such as stop check valves to prevent 
progressive flooding to other spaces with which they connect; or
    (2) Assumed in the design calculations required by Sec.  172.130 to 
flood the spaces with which they connect.
    (e) Buoyancy of superstructure. The buoyancy of any superstructure 
directly above the side damage is to be disregarded. The unflooded parts 
of superstructures beyond the extent of damage may be taken into 
consideration if they are separated from the damaged space by watertight 
bulkheads and no progressive flooding of these intact spaces takes 
place.
    (f) Metacentric height. After flooding, the tankship's metacentric 
height must be at least 2 inches (50mm) when the ship is in the upright 
position.
    (g) Equalization arrangements. Flooding equalization arrangements 
requiring mechanical operation such as valves or cross-flooding lines 
may not be assumed to reduce the angle of heel. Spaces joined by ducts 
of large cross sectional area are treated as common spaces.
    (h) Intermediate stages of flooding. If an intermediate stage of 
flooding is more critical than the final stage, the tankship must be 
shown by design calculations to meet the requirements in this section in 
the intermediate stage.

    (a) Design calculations must show that 2 inches (50mm) of positive 
metacentric height can be maintained by each tankship when it is being 
loaded and unloaded.
    (b) For the purpose of demonstrating compliance with the 
requirements of paragraph (a) of this section, the effects of the 
addition of water ballast may be considered.



Sec.  172.170  Damage stability calculations.

    (a) Each tankship must be shown by design calculations to meet the

type specified in Table 4 of part 154 of this chapter.
    (b) If a cargo listed in Table 4 of part 154 of this chapter is to 
be carried, the vessel must be at least the ship type specified in Table 
4 of part 154 of this chapter for the cargo.



Sec.  172.175  Character of damage.

    (a) If a type IG hull is required, design calculations must show 
that the vessel can survive damage at any location.
    (b) If a type IIG hull is required, design calculations must show 
that a vessel--
    (1) Longer than 492 feet (150 meters) in length can survive damage 
at any location; and
    (2) 492 feet (150 meters) or less in length can survive damage at 
any location except the transverse bulkheads bounding an aft machinery 
space. The machinery space is calculated as a single floodable 
compartment.
    (c) If a vessel has independent tanks type C with a MARVS of 100 psi 
(689 kPa) gauge or greater, is 492 feet (150 meters) or less in length, 
and Table 4 of part 154 of this chapter allows a type IIPG hull, design 
calculations must show that the vessel can survive damage at any 
location, except as prescribed in paragraph (e) of this section.
    (d) If a type IIIG hull is required, except as specified in 
paragraph (e) of this section, design calculations must show that a 
vessel--
    (1) 410 feet (125 meters) in length or longer can survive damage at 
any location; and
    (2) Less than 410 feet (125 meters) in length can survive damage at 
any location, except in the main machinery space.
    (e) The calculations in paragraphs (c) and (d) of this section need 
not assume damage to a transverse bulkhead unless it is spaced closer 
than the longitudinal extent of collision penetration specified in Table 
172.180 from another transverse bulkhead.
    (f) If a main transverse watertight bulkhead or transverse 
watertight bulkhead bounding a side tank or double bottom tank has a 
step or a recess that is longer than 10 feet (3.05 meters) located 
within the extent of penetration of assumed damage, the vessel must be 
shown by design calculations to survive damage to this bulkhead. The 
step formed by the after peak bulkhead and after peak tank top is not a 
step for the purpose of this regulation.



Sec.  172.180  Extent of damage.

    For the purpose of Sec.  172.170--
    (a) Design calculations must include both side and bottom damage, 
applied separately; and

Sec.  172.185  Permeability of spaces.

    (a) When doing the calculations required in Sec.  172.170, the 
permeability of a floodable space other than a machinery space must be 
as listed in Table 172.060(b).
    (b) Calculations in which a machinery space is treated as a 
floodable space must be based on an assumed machinery space permeability 
of 85%, unless the use of an assumed permeability of less than 85% is 
justified in detail.
    (c) If a cargo tank would be penetrated under the assumed damage, 
the cargo tank must be assumed to lose all cargo and refill with salt 
water up to the level of the tankship's final equilibrium waterline.



Sec.  172.195  Survival conditions.

    A vessel is presumed to survive assumed damage if it meets the 
following conditions in the final stage of flooding:
    (a) Final waterline. The final waterline, in the final condition of 
sinkage, heel, and trim, must be below the lower edge of an opening 
through which progressive flooding may take place, such as an air pipe, 
or an opening that is closed by means of a weathertight door or hatch 
cover. This opening does not include an opening closed by a--
    (1) Watertight manhole cover;
    (2) Flush scuttle;
    (3) Small watertight cargo tank hatch cover that maintains the high 
integrity of the deck;
    (4) A Class 1 door in a watertight bulkhead within the 
superstructure;
    (5) Remotely operated sliding watertight door; or
    (6) A side scuttle of the non-opening type.
    (b) Heel angle. The maximum angle of heel must not exceed 30 
degrees.
    (c) Range of stability. Through an angle of 20 degrees beyond its 
position of equilibrium after flooding, a tankship must meet the 
following conditions:
    (1) The righting arm curve must be positive.
    (2) The maximum righting arm must be at least 3.94 inches (10 cm).
    (3) Each submerged opening must be weathertight.
    (d) Progressive flooding. If pipes, ducts, or tunnels are within the 
assumed extent of damage, arrangements must be made to prevent 
progressive flooding to a space that is not assumed to be flooded in the 
damaged stability calculations.
    (e) Buoyancy of superstructure. The buoyancy of any superstructure 
directly above the side damage is to be disregarded. The unflooded parts 
of superstructures beyond the extent of damage may be taken into 
consideration if they are separated from the damaged space by watertight 
bulkheads and no progressive flooding of these intact spaces takes 
place.
    (f) Metacentric height. After flooding, the tank ship's metacentric 
height must be at least 2 inches (50 mm) when the vessel is in the 
upright position.
    (g) Equalization arrangements. Equalization arrangements requiring 
mechanical aids such as valves or cross-flooding lines may not be 
considered for reducing the angle of heel. Spaces joined by ducts of 
large cross-sectional area are treated as common spaces.
    (h) Intermediate stages of flooding. If an intermediate stage of 
flooding is more critical than the final stage, the tank vessel must be 
shown by design calculations to meet the requirements in this section in 
the intermediate stage.



Sec.  172.205  Local damage.

    (a) Each tankship must be shown by design calculations to meet the 
survival conditions in paragraph (b) of this section in each condition 
of loading and operation assuming that local damage extending 30 inches 
(76 cm)

[[Page 148]]

normal to the hull shell is applied at any location in the cargo length:
    (b) The vessel is presumed to survive assumed local damage if it 
does not heel beyond the smaller of the following angles in the final 
stage of flooding:
    (1) 30 degrees.
    (2) The angle at which restoration of propulsion and steering, and 
use of the ballast system is precluded.

Sec.  172.225  Calculations.

    (a) Each vessel must be shown by design calculations to meet the 
survival conditions in Sec.  172.245 in each condition of loading and 
operation, assuming the damage specified in Sec.  172.230.
    (b) When doing the calculations required by paragraph (a) of this 
section, the virtual increase in the vertical center of gravity due to a 
liquid in a space must be determined by calculating either--
    (1) The free surface effect of the liquid with the vessel assumed 
heeled five degrees from the vertical; or
    (2) The shift of the center of gravity of the liquid by the moment 
of transference method.
    (c) In calculating the free surface effect of consumable liquids, it 
must be assumed that, for each type of liquid, at least one transverse 
pair of wing tanks or a single centerline tank has a free surface. The 
tank or combination of tanks selected must be those having the greatest 
free surface effect.
    (d) When doing the calculations required by paragraph (a) of this 
section, the buoyancy of any superstructure directly above the side 
damage must not be considered. The unflooded parts of superstructures 
beyond the extent of damage may be considered if they are separated from 
the damaged space by watertight bulkheads and no progressive flooding of 
these intact spaces takes place.



Sec.  172.230  Character of damage.

    (a) Design calculations must show that each vessel can survive 
damage--
    (1) To any location between adjacent main transverse watertight 
bulkheads;
    (2) To any location between a main transverse bulkhead and a partial 
transverse bulkhead in way of a side wing tank;
    (3) To a main or wing tank transverse watertight bulkhead spaced 
closer than the longitudinal extent of collision penetration specified 
in Table 172.235 to another main transverse watertight bulkhead; and
    (4) To a main transverse watertight bulkhead or a transverse 
watertight bulkhead bounding a side tank or double bottom tank if there 
is a step or a recess in the transverse bulkhead that is longer than 10 
feet (3.05 meters) and that is located within the extent of penetration 
of assumed damage. The step formed by the after peak bulkhead and after 
peak tank top is not a step for the purpose of this paragraph.



Sec.  172.235  Extent of damage.

    For the purpose of the calculations required in Sec.  172.225--
    (a) Design calculations must include both side and bottom damage, 
applied separately; and
    (b) Damage must consist of the penetrations having the dimensions 
given in Table 172.235 except that, if the most

[[Page 149]]

disabling penetrations would be less than the penetrations described in 
this paragraph, the smaller penetration must be assumed.

    When doing the calculations required in Sec.  172.225,
    (a) The permeability of a floodable space, other than a machinery or 
cargo space, must be assumed as listed in Table 172.240;
    (b) Calculations in which a machinery space is treated as a 
floodable space must be based on an assumed machinery space permeability 
of 85% unless the use of an assumed permeability of less than 85% is

considered flooded must be based on an assumed cargo space permeability 
of 60% unless the use of an assumed permeability of less than 60% is 
justified in detail. If the cargo space is not completely filled, a 
cargo space permeability of 95% must be assumed unless the use of an 
assumed permeability of less than 95% is justified in detail.

Sec.  172.245  Survival conditions.

    A vessel is presumed to survive assumed damage if it meets the 
following conditions in the final stage of flooding:
    (a) Final waterline. The final waterline, in the final condition of 
sinkage, heel, and trim must be below the lower edge of an opening 
through which progressive flooding may take place, such as an air pipe, 
or an opening that is closed by means of a weathertight door or hatch 
cover. This opening does not include an opening closed by a:
    (1) Watertight manhole cover;
    (2) Flush scuttle;
    (3) Small watertight cargo tank hatch cover that maintains the high 
integrity of the deck;
    (4) Class 1 door in a watertight bulkhead;
    (5) Remotely operated sliding watertight door;
    (6) Side scuttle of the nonopening type;
    (7) Retractable inflatable seal; or
    (8) Guillotine door.
    (b) Heel angle. The maximum angle of heel must not exceed 15 
degrees, except that this angle may be increased to 17 degrees if no 
deck edge immersion occurs.
    (c) Range of stability. Through an angle of 20 degrees beyond its 
position of equilibrium after flooding, a vessel must meet the following 
conditions:
    (1) The righting arm curve must be positive.
    (2) The maximum righting arm must be at least 4 inches (10 cm).
    (3) Each submerged opening must be weathertight
    (d) Metacentric height. After flooding, the metacentric height must 
be at least 2 inches (50 mm) when the vessel is in the equilibrium 
position.

[[Page 150]]

    (e) Progressive flooding. In the design calculations required by 
Sec.  172.225, progressive flooding between spaces connected by pipes, 
ducts or tunnels must be assumed unless:
    (1) Pipes within the assumed extent of damage are equipped with 
arrangements such as stop check valves to prevent progressive flooding 
to other spaces with which they connect; and,
    (2) Progressive flooding through ducts or tunnels is protected 
against by:
    (i) Retractable inflatable seals to cargo hopper gates; or
    (ii) Guillotine doors in bulkheads in way of the conveyor belt.

  Subpart C_Special Rules Pertaining to Mobile Offshore Drilling Units



Sec.  174.030  Specific applicability.

    Each mobile offshore drilling unit (MODU) inspected under Subchapter 
IA of this chapter must comply with this subpart.



Sec.  174.035  Definitions.

    (a) For the purpose of this subpart the following terms have the 
same definitions as given in subchapter IA of this chapter:
    (1) Column stabilized unit.
    (2) Mobile offshore drilling unit.
    (3) Self-elevating unit.
    (4) Surface type unit.
    (b) For the purpose of this subpart--
    (1) Downflooding means the entry of seawater through any opening 
that cannot be rapidly closed watertight, into the hull, superstructure, 
or columns of an undamaged unit due to heel, trim, or submergence of the 
unit.
    (2) Downflooding angle means the static angle from the intersection 
of the unit's centerline and waterline in calm water to the first 
opening through which downflooding can occur when subjected to a wind 
heeling moment (Hm) calculated in accordance with Sec.  174.055.
    (3) Normal operating condition means a condition of a unit when 
loaded or arranged for drilling, field transit, or ocean transit.
    (4) Severe storm condition means a condition of a unit when loaded 
or arranged to withstand the passage of a severe storm.



Sec.  174.040  Stability requirements: general.

    Each unit must be designed to have at least 2 inches (50mm) of 
positive metacentric height in the upright equilibrium position for the 
full range of drafts, whether at the operating draft for navigation, 
towing, or drilling afloat, or at a temporary draft when changing 
drafts.



Sec.  174.045  Intact stability requirements.

    (a) Each unit must be designed so that the wind heeling moments (Hm) 
and righting moments calculated for each of its normal operating 
conditions

[[Page 163]]

and severe storm conditions, when plotted on GRAPH 174.045, define areas 
that satisfy the equation:

Area(A)=(K) x (Area (B))

where--

(1) K = 1.4 except that if the unit is a column stabilized unit K = 1.3;
(2) Area (A) is the area on GRAPH 174.045 under the righting moment 
          curve between 0 and the second intercept angle or the angle of 
          heel at which downflooding would occur, whichever angle is 
          less; and
(3) Area (B) is the area on GRAPH 174.045 under the wind heeling moment 
          curve between 0 and the second intercept angle or the angle of 
          heel at which downflooding of the unit would occur whichever 
          angle is less.

    (b) Each righting moment on graph Sec.  174.045 must be positive for 
all angles greater than 0 and less than the second intercept angle.
    (c) For the purposes of this section, openings fitted with the 
weathertight closing appliances specified in Sec.  174.100(b) are not 
considered as openings through which downflooding could occur if they 
can be rapidly closed and would not be submerged below the units' 
waterline prior to the first intercept angle, except that ventilation 
intakes and outlets for machinery spaces, crew spaces, and other spaces 
where ventilation is normally required are considered as openings 
through which downflooding could occur regardless of location.
    (d) Each unit must be designed so that it can be changed from each 
of its normal operating conditions to a severe storm condition within a 
minimum period of time consistent with the operating manual required in 
Sec.  109.121 of this chapter.

6979, Mar. 6, 1987]



Sec.  174.050  Stability on bottom.

    Each bottom bearing unit must be designed so that, while supported 
on the sea bottom with footings or a mat, it continually exerts a 
downward force on each footing or the mat when subjected to the forces 
of wave and current and to wind blowing at the velocities described in 
Sec.  174.055(b)(3).



Sec.  174.055  Calculation of wind heeling moment (Hm).

    (a) The wind heeling moment (Hm) of a unit in a given normal 
operating condition or severe storm condition is the sum of the 
individual wind heeling moments (H) calculated for each of the exposed 
surfaces on the unit; i.e., Hm=[Sigma] H.
    (b) Each wind heeling moment (H) must be calculated using the 
equation:

H = k(v)\2\(Ch)(Cs)(A)(h)

where--

(1) H = wind heeling moment for an exposed surface on the unit in foot-
          pounds (kilogram-meters);
(2) k = 0.00338 lb./(ft.\2\-knots\2\) (0.0623 (kg-sec\2\)/m\4\);
(3) v = wind velocity of--
(i) 70 knots (36 meters per second) for normal operating conditions.
(ii) 100 knots (51.5 meters per second) for severe storm conditions.
(iii) 50 knots (25.8 meters per second) for damage conditions.

[[Page 165]]

(4) A = projected area in square feet (square meters) of an exposed 
          surface on the unit;
(5) Ch = height coefficient for ``A'' from Table 174.055(a);
(6) Cs = shape coefficient for ``A'' from Table 174.055(b); and
(7) h = the vertical distance in feet (meters) from the center of 
          lateral resistance of the underwater hull to the center of 
          wind pressure on ``A''.

    (c) When calculating ``A'' in the equation described in paragraph 
(b) of this section--
    (1) The projected area of each column or leg; if the unit has 
columns or legs, must not include shielding allowances;
    (2) Each area exposed as a result of heel must be included;
    (3) The projected area of a cluster of deck houses may be used 
instead of the projected area of each individual deck house in the 
cluster; and
    (4) The projected area of open truss work may be calculated by 
taking 30% of the projected areas of both the front and back sides of 
the open truss work rather than by determining the projected area of 
each structural member of the truss work.

Sec.  174.065  Damage stability requirements.

    (a) Each unit must be designed so that, while in each of its normal 
operating conditions and severe storm conditions, its final equilibrium 
waterline would remain below the lowest edge of any opening through 
which additional flooding could occur if the unit were subjected 
simultaneously to--
    (1) Damage causing flooding described in Sec. Sec.  174.075 through 
174.085; and
    (2) A wind heeling moment calculated in accordance with Sec.  
174.055(b) using a wind velocity of 50 knots (25.8 meters per second).
    (b) Each unit must have a means to close off each pipe, ventilation 
system, and trunk in each compartment described in Sec.  174.080 or 
Sec.  174.085 if any portion of the pipe, ventilation system, or trunk 
is within 5 feet (1.5 meters) of the hull.



Sec.  174.070  General damage stability assumptions.

    For the purpose of determining compliance with Sec.  174.065, the 
assumptions are made that during flooding and the resulting change in 
the unit's waterline--
    (a) The unit is not anchored or moored; and
    (b) No compartment on the unit is ballasted or pumped out to 
compensate for the flooding described in Sec. Sec.  174.075 through 
174.085.



Sec.  174.075  Compartments assumed flooded: general.

    The individual flooding of each of the compartments described in 
Sec. Sec.  174.080 and 174.085 must be assumed for the purpose of 
determining compliance

[[Page 166]]

with Sec.  174.065 (a). Simultaneous flooding of more than one 
compartment must be assumed only when indicated in Sec. Sec.  174.080 
and 174.085.



Sec.  174.080  Flooding on self-elevating and surface type units.

    (a) On a surface type unit or self-elevating unit, all compartments 
within 5 feet (1.5 meters) of the hull of the unit between two adjacent 
main watertight bulkheads, the bottom shell, and the uppermost 
continuous deck or first superstructure deck where superstructures are 
fitted must be assumed to be subject to simultaneous flooding.
    (b) On the mat of a self-elevating unit, all compartments of the mat 
must be assumed to be subject to individual flooding.



Sec.  174.085  Flooding on column stabilized units.

    (a) Watertight compartments that are outboard of, or traversed by, a 
plane which connects the vertical centerlines of the columns on the 
periphery of the unit, and within 5 feet (1.5 meters) of an outer 
surface of a column or footing on the periphery of the unit, must be 
assumed to be subject to flooding as follows:
    (1) When a column is subdivided into watertight compartments by 
horizontal watertight flats, all compartments in the column within 5 
feet (1.5 meters) of the unit's waterline before damage causing flooding 
must be assumed to be subject to simultaneous flooding.
    (2) When a column is subdivided into watertight compartments by 
vertical watertight bulkheads, each two adjacent compartments must be 
assumed subject to simultaneous flooding if the distance between the 
vertical watertight bulkheads, measured at the column periphery, is 
equal to or less than one-eighth of the column perimeter at the draft 
under consideration.
    (3) When a column is subdivided into watertight compartments by 
horizontal watertight flats and vertical watertight bulkheads, those 
compartments that are within the bounds described in paragraph (a)(2) of 
this section and within 5 feet (1.5 meters) of the unit's waterline 
before damage causing flooding must be assumed to be subject to 
simultaneous flooding.
    (b) Each compartment in a footing must be assumed to be subject to 
individual flooding when any part of the compartment is within 5 feet 
(1.5 meters) of the unit's waterline before damage causing flooding.



Sec.  174.090  Permeability of spaces.

    When doing the calculations required in Sec.  174.065--
    (a) The permeability of a floodable space, other than a machinery 
space, must be as listed in Table 174.090; and
    (b) Calculations in which a machinery space is treated as a 
floodable space must be based on an assumed machinery space permeability 
of 85%, unless the use of an assumed permeability of less than 85% is 
justified in detail.

                       Table 174.090--Permeability
------------------------------------------------------------------------
              Spaces and tanks                  Permeability (percent)

Storeroom spaces...........................  60.
Accommodation spaces.......................  95.
Voids......................................  95.
Consumable liquid tanks....................  95 or 0. \1\
Other liquid tanks.........................  95 or 0. \2\
------------------------------------------------------------------------
\1\ Whichever results in the more disabling condition.
\2\ If tanks are partially filled, the permeability must be determined
  from the actual density and amount of liquid carried.



Sec.  174.100  Appliances for watertight and weathertight integrity.

    (a) Appliances to insure watertight integrity include watertight 
doors, hatches, scuttles, bolted manhole covers, or other watertight 
closures for openings in watertight decks and bulkheads.
    (b) Appliances to insure weathertight integrity include weathertight 
doors and hatches, closures for air pipes, ventilators, ventilation 
intakes and outlets, and closures for other openings in deckhouses and 
superstructures.
    (c) Each internal opening equipped with appliances to insure 
watertight integrity that is used intermittently during operation of the 
unit while afloat must meet the following:
    (1) Each door, hatch, and scuttle must--
    (i) Be remotely controlled from a normally manned control station, 
and be operable locally from both sides of the bulkhead; or

[[Page 167]]

    (ii) If there is no means of remote control there must be an alarm 
system that signals whether the appliance is open or closed both locally 
at each appliance and in a normally manned control station.
    (2) Each closing appliance must remain watertight under the design 
water pressure of the watertight boundary of which it is a part.
    (d) Each external opening fitted with an appliance to insure 
weathertight integrity must be located so that it would not be submerged 
below the final equilibrium waterline if the unit is subjected 
simultaneously to--
    (1) Damage causing flooding described in Sec. Sec.  174.075 through 
174.085; and
    (2) A wind heeling moment calculated in accordance with Sec.  
174.055 using a wind velocity of 50 knots (25.8 meters per second).
    (e) If a unit is equipped with sliding watertight doors, each 
sliding watertight door must--
    (1) Be designed, constructed, tested, and marked in accordance with 
ASTM F 1196 (incorporated by reference, see Sec.  174.007);
    (2) Have controls in accordance with ASTM F 1197 (incorporated by 
reference, see Sec.  174.007), except that a remote manual means of 
closure, as specified in paragraphs 7.1 and 7.5.1, and a remote 
mechanical indicator, as specified in paragraph 7.5.2, will not be 
required; and
    (3) If installed in a subdivision bulkhead, meet Supplemental 
Requirements Nos. S1 and S3 of ASTM F 1196 (incorporated by reference, 
see Sec.  174.007), unless the watertight doors are built in accordance 
with plans previously approved by the Coast Guard, in which case, only 
Supplemental Requirements Nos. S1 and S3.1.4 of ASTM F 1196 
(incorporated by reference, see Sec.  174.007) must be met. In either 
case, control systems for watertight doors must have power supplies, 
power sources, installation tests and inspection, and additional remote 
operating consoles in accordance with Supplemental Requirements Nos. S1 
through S4 of ASTM F 1197 (incorporated by reference, see Sec.  
174.007).
    (f) Installations of sliding watertight door assemblies must be in 
accordance with the following:
    (1) Before a sliding watertight door assembly is installed in a 
vessel, the bulkhead in the vicinity of the door opening must be 
stiffened. Such bulkhead stiffeners, or deck reinforcement where flush 
deck door openings are desired, must not be less than 6 inches nor more 
than 12 inches from the door frame so that an unstiffened diaphragm of 
bulkhead plating 6 to 12 inches wide is provided completely around the 
door frame. Where such limits cannot be maintained, alternative 
installations will be considered by the Marine Safety Center. In 
determining the scantlings of these bulkhead stiffeners, the door frame 
should not be considered as contributing to the strength of the 
bulkhead. Provision must also be made to adequately support the thrust 
bearings and other equipment that may be mounted on the bulkhead or 
deck.
    (2) Sliding watertight door frames must be either bolted or welded 
watertight to the bulkhead.
    (i) If bolted, a suitable thin heat and fire resistant gasket or 
suitable compound must be used between the bulkhead and the frame for 
watertightness. The bulkhead plating shall be worked to a plane surface 
in way of the frame when mounting.
    (ii) If welded, caution must be exercised in the welding process so 
that the door frame is not distorted.

flooding:
    (1) Final waterline. The final waterline, in the final stage of 
sinkage, heel, and trim, must be below the lower edge of an opening 
through which progressive flooding may take place, such as an air pipe, 
a tonnage opening, an opening closed by a weathertight door or hatch-
cover, or a tank vent fitted with a ball check-valve. This opening does 
not include an opening closed by a--
    (i) Watertight manhole-cover;
    (ii) Flush scuttle;
    (iii) Small hatch-cover for a watertight cargo-tank that maintains 
the high integrity of the deck;
    (iv) Watertight door in compliance with Sec.  174.210 of this 
subpart; or
    (v) Side scuttle of the non-opening type.
    (2) Angle of heel. The angle of heel must not exceed 15 degrees.
    (3) Range of stability. Through an angle of 20 degrees beyond its 
position of equilibrium after flooding, an OSV must meet the following 
conditions:
    (i) The righting arm curve must be positive.
    (ii) The righting arm must be at least 100 millimeters (4 inches).
    (iii) Each submerged opening must be weathertight. (A tank vent 
fitted with a ball check-valve is weathertight.)

[[Page 170]]

    (4) Progressive flooding. Piping, ducts, or tunnels within the 
assumed extent of damage must be either--
    (i) Equipped with arrangements, such as stop check-valves, to 
prevent progressive flooding of the spaces with which they connect; or
    (ii) Assumed in the calculations required by paragraph (a) of this 
section to permit progressive flooding of the spaces with which they 
connect.
    (d) Buoyancy of superstructure. For paragraph (a) of this section, 
the buoyancy of any superstructure directly above the side damage must 
be considered in the most unfavorable condition.

where superstructures are fitted must be assumed subject to simultaneous 
flooding.
    (5) In the calculations required by paragraph (b)(1) of this 
section, the permeability of a floodable space must be as listed by 
Table 174.205(d).
    (c) On-bottom stability. Each liftboat must be shown by design

Sec.  175.118  Vessels operating under an exemption afforded in the
Passenger Vessel Safety Act of 1993 (PVSA).

    (a) The Passenger Vessel Safety Act of 1993 (PVSA) contained an 
allowance for the exemption of certain passenger vessels that are--
    (1) At least 100 gross tons but less than 300 gross tons; or
    (2) Former public vessels of at least 100 gross tons but less than 
500 gross tons.
    (b) The owner or operator of a vessel must have applied for an 
exemption under PVSA by June 21, 1994, and then brought the vessel into 
compliance with the interim guidance in Navigation and Inspection 
Circular (NVIC) 7-94 not later than December 21, 1996. The PVSA 
exemption is valid for the service life of the vessel, as long as the 
vessel remains certified for passenger service. If the Certificate of 
Inspection (COI) is surrendered or otherwise becomes invalid (not 
including a term while the vessel is out of service but undergoing an 
inspection for recertification), the owner or operator must meet the 
appropriate inspection regulations to obtain a new COI without the PVSA 
exemption.
    (c) Except where the provisions of subchapter H of this chapter 
apply, the owner or operator must ensure that the vessel meets the 
requirements of this subchapter, meets any requirements the OCMI deems 
applicable, and meets any specific additions or exceptions as follows:
    (1) If a vessel does not meet the intact stability requirements of 
subchapter S of this chapter, the vessel's route(s) will be limited to 
an area within 20 nautical miles from a harbor of safe refuge, provided 
the vessel has a history of safe operation on those waters. The OCMI may 
further restrict the vessel's routes if the vessel's service history, 
condition, or other factors affect its seaworthiness or safety.
    (2) The vessel may not carry more than 150 passengers, and not more 
than 49 passengers in overnight accommodations.
    (3) The owner or operator must crew the vessel under the 
requirements of this subchapter. All officers must be endorsed for the 
appropriate vessel tonnage. The OCMI may require an appropriately 
endorsed engineer officer for those vessels of at least 200 gross tons.

[[Page 177]]

Vessels carrying more than 50 passengers must have an additional 
deckhand, and all deckhands on vessels carrying more than 50 passengers 
must be adequately trained. The crew members on a vessel of at least 200 
gross tons, except those operated exclusively on lakes and rivers, are 
required to hold merchant mariner credentials or merchant mariner 
documents and 50 percent of the merchant mariner credentials or at least 
an able seaman.
    (4) The vessel owner or operator must comply with the lifesaving 
arrangements located in part 180 of this chapter, except that inflatable 
liferafts are required for primary lifesaving. A rescue boat or suitable 
rescue arrangement must be provided to the satisfaction of the OCMI.
    (5) The vessel owner or operator must comply with the fire 
protection requirements located in part 181 of this chapter. When a 
vessel fails to meet the fire protection and structural fire protection 
requirements of this subchapter, the vessel owner or operator must meet 
equivalent requirements to the satisfaction of the cognizant OCMI or 
submit plans for approval from the Coast Guard Marine Safety Center.
    (6) At a minimum, the owner or operator must outfit the vessel with 
portable fire extinguishers per 46 CFR 76.50. In addition, the vessel 
must meet any additional requirements of the OCMI, even if they exceed 
the requirements in 46 CFR 76.50.
    (7) In addition to the means-of-escape requirements of 46 CFR 
177.500, the vessel owner or operator must also meet the requirements 
for means of escape found in 46 CFR 78.47-40.
    (d) The OCMI conducts an inspection and may issue a COI if the 
vessel meets these requirements. The COI's condition of operation must 
contain the following endorsement: ``This vessel is operating under an 
exemption afforded in The Passenger Vessel Safety Act of 1993 and as 
such is limited to domestic voyages and a maximum ______ of passengers 
and may be subject to additional regulations and restrictions as 
provided for in Sections 511 and 512 of the Act.''

Sec.  175.200  Gross tonnage as criterion for requirements.

    (a) The regulations in this subchapter take into account a vessel's 
length, passenger capacity, construction, equipment, intended service, 
and operating area. The criterion for application of this subchapter is 
the gross tonnage of the vessel. When the Commandant determines that the 
gross tonnage of a particular vessel, which is attained by exemptions, 
reductions, or other devices in the basic gross tonnage formulation, 
will circumvent or be incompatible with the application of specific 
regulations for a vessel of such physical size, the Commandant will 
prescribe the regulations to be made applicable to the vessel.
    (b) When the Commandant determines that the gross tonnage is not a 
valid criterion for the use of certain regulations based on the relative 
size of the vessel, the owner will be informed of the determination and 
of the regulations applicable to the vessel. The vessel must be brought 
into compliance with all additional requirements before a Certificate of 
Inspection is issued.

days of expiration and the certificate did not expire within 15 days of 
sailing on the foreign voyage from a U.S. port.

[CGD 85-080, 61 FR 953, Jan. 10, 1996; 61 FR 20557, May 7, 1996]



Sec.  176.103  Description.

    The Certificate of Inspection issued to a vessel describes the 
vessel, the route(s) that it may travel, the minimum manning 
requirements, the survival and rescue craft carried, the minimum fire 
extinguishing equipment and lifejackets required to be carried, the 
maximum number of passengers and total persons that may be carried, the 
number of passengers the vessel may carry in overnight accommodation 
spaces, the name of the owner and managing operator, any equivalencies 
accepted or authorized by the Commandant or any Officer in Charge, 
Marine Inspection (OCMI) in accordance with Sec.  175.540 or Sec.  
175.550 of this chapter, and such other conditions of operations as may

    (c) A Certificate of Inspection may be suspended and withdrawn or 
revoked by the cognizant OCMI at any time for noncompliance with the 
requirements of this subchapter.

[USCG-1999-4976, 65 FR 6508, Feb. 9, 2000]



Sec.  176.110  Routes permitted.

    (a) The area of operation for each vessel and any necessary 
operational limits are determined by the cognizant OCMI, and recorded on 
the vessel's Certificate of Inspection. Each area of operation, referred 
to as a route, is described on the Certificate of Inspection under the 
major headings ``Oceans,'' ``Coastwise,'' ``Limited Coastwise,'' ``Great 
Lakes,'' ``Lakes, Bays, and Sounds,'' or ``Rivers,'' as applicable.

[[Page 193]]

Further limitations imposed or extensions granted are described by 
reference to bodies of waters, geographical points, distance from 
geographical points, distances from land, depths of channel, seasonal 
limitations, and similar factors.
    (b) Operation of a vessel on a route of lesser severity than those 
specifically described or designated on the Certificate of Inspection is 
permitted unless expressly prohibited on the Certificate of Inspection. 
The general order of severity of routes is: oceans, coastwise, limited 
coastwise, Great Lakes, lakes, bays, and sounds, and rivers. The 
cognizant OCMI may prohibit a vessel from operating on a route of lesser 
severity than the primary route a vessel is authorized to operate on if 
local conditions necessitate such a restriction.
    (c) Non-self-propelled vessels are prohibited from operating on an 
oceans, coastwise, limited coastwise, or Great Lakes route unless the 
Commandant approves such a route.
    (d) When designating a permitted route or imposing any operational 
limits on a vessel, the OCMI may consider:
    (1) Requirements of this subchapter for which compliance is based on 
the route of the vessel;
    (2) The performance capabilities of the vessel based on design, 
scantlings, stability, subdivision, propulsion, speed, operating modes, 
maneuverability, and other characteristics;
    (3) The suitability of the vessel for nighttime operations; and
    (4) The suitability of the vessel for all environmental conditions.

[CGD 85-080, 61 FR 953, Jan. 10, 1996; 61 FR 20557, May 7, 1996, as 
amended by USCG-2007-0030, 75 FR 78087, Dec. 14, 2010]



Sec.  176.112  Total persons permitted.

    The cognizant Officer in Charge, Marine Inspection (OCMI) determines 
the total number of persons permitted to be carried on a vessel. In 
determining the total number of persons, the OCMI may consider the total 
weight of passengers, crew, and variable loads; stability restrictions 
and subdivision requirements of the vessel; the vessel's route, general 
arrangement, means of escape, and lifesaving equipment; minimum manning 
requirements; and the maximum number of passengers permitted in 
accordance with Sec.  176.113 of this part.

[USCG-2007-0030, 75 FR 78087, Dec. 14, 2010]



Sec.  176.113  Passengers permitted.

    (a) The maximum number of passengers permitted must be not more than 
that allowed by the requirements of this section, except as authorized 
by the OCMI under paragraph (d) of this section.
    (b) The maximum number of passengers permitted on any vessel may be 
the greatest number permitted by the length of rail criterion, deck area 
criterion, or fixed seating criterion described in this paragraph or a 
combination of these criteria as allowed by paragraph (c) of this 
section.
    (1) Length of rail criterion. One passenger may be permitted for 
each 760 millimeters (30 inches) of rail space available to the 
passengers at the periphery of each deck. The following rail space may 
not be used in determining the maximum number of passengers permitted:
    (i) Rail space in congested areas unsafe for passengers, such as 
near anchor handling equipment or line handling gear, in the way of sail 
booms, running rigging, or paddle wheels, or along pulpits;
    (ii) Rail space on stairways; and
    (iii) Rail space where persons standing in the space would block the 
vision of the individual operating the vessel.
    (2) Deck area criterion. One passenger may be permitted for each 0.9 
square meters (10 square feet) of deck area available for the 
passengers' use. In computing such deck area, the areas occupied by the 
following must be excluded;
    (i) Areas for which the number of persons permitted is determined 
using the fixed seating criteria;
    (ii) Obstructions, including stairway and elevator enclosures, 
elevated stages, bars, and cashier stands, but not including slot 
machines, tables, or other room furnishings;
    (iii) Toilets and washrooms;
    (iv) Spaces occupied by and necessary for handling lifesaving 
equipment, anchor handling equipment or line handling gear, or in the 
way of sail booms or running rigging;

[[Page 194]]

    (v) Spaces below deck that are unsuitable for passengers or that 
would not normally be used by passengers;
    (vi) Interior passageways less than 840 millimeters (34 inches) wide 
and passageways on open deck, less than 710 millimeters (28 inches) 
wide;
    (vii) Bow pulpits, swimming platforms and areas that do not have a 
solid deck, such as netting on multi-hull vessels;
    (viii) Deck areas in way of paddle wheels; and
    (ix) Aisle area provided in accordance with Sec.  177.820(d) in this 
subchapter.
    (3) Fixed seating criterion. One passenger may be permitted for each 
455 millimeter (18 inches) of width of fixed seating provided by Sec.  
177.820 of this subchapter. Each sleeping berth in overnight 
accommodation spaces shall be counted as only one seat.
    (c) Different passenger capacity criteria may be used on each deck 
of a vessel and added together to determine the total passenger capacity 
of that vessel. Where seats are provided on part of a deck and not on 
another, the number of passengers permitted on a vessel may be the sum 
of the number permitted by the seating criterion for the space having 
seats and the number permitted by the deck area criterion for the space 
having no seats. The length of rail criterion may not be combined with 
either the deck area criterion or the fixed seating criterion when 
determining the maximum number of passengers permitted on an individual 
deck.
    (d) For a vessel operating on short runs on protected waters such as 
a ferry, the cognizant OCMI may give special consideration to increases 
in passenger allowances.

[CGD 85-080, 61 FR 953, Jan. 10, 1996, as amended by USCG-2006-24371, 74 
FR 11266, Mar. 16, 2009]



Sec.  176.114  Alternative requirements for a vessel operating as other
than a small passenger vessel.

    (a) When authorized by the cognizant OCMI by an endorsement of the 
vessel's Certificate of Inspection, a small passenger vessel carrying 
six or less passengers, or operating as a commercial fishing vessel or 
other uninspected vessel, or carrying less than twelve passengers and 
operating as a recreational vessel, need not meet requirements of:
    (1) Subparts C, D, and E, of part 180 of this chapter if the vessel 
is in satisfactory compliance with the lifesaving equipment regulations 
for an uninspected vessel or recreational vessel in a similar service;
    (2) Subpart C of part 177, and parts 178 and 179 of this chapter if 
the vessel is in satisfactory compliance with applicable regulations for 
an uninspected vessel or recreational vessel in a similar service or if 
the owner of the vessel otherwise establishes to the satisfaction of the 
cognizant OCMI that the vessel is seaworthy for the intended service; 
and
    (3) Sections 184.404 and 184.410 of this chapter providing the 
vessel is in satisfactory compliance with applicable regulations for an 
uninspected or recreational vessel in a similar service.
    (b) A vessel operating under the alternative regulations of 
paragraph (a) of this section must:
    (1) Not alter the arrangement of the vessel nor remove any equipment 
required by the certificate for the intended operation, without the 
consent of the cognizant OCMI;
    (2) Comply with the minimum manning specified on the Certificate of 
Inspection, which may include reduced manning depending on the number of 
passengers and operation of the vessel;
    (3) When carrying from one to six passengers, except for a vessel 
being operated as a recreational vessel, make the announcement required 
by Sec.  185.506(a) of this chapter before getting underway; and
    (4) If a vessel of more than 15 gross tons, not carry freight for 
hire.
    (c) The endorsement issued under paragraph (a) of this section must 
indicate the route, maximum number of passengers, and the manning 
required to operate under the provisions of this section.

[CGD 85-080, 61 FR 953, Jan. 10, 1996, as amended by CGD 97-057, 62 FR 
51049, Sept. 30, 1997]



Sec.  176.120  Certificate of Inspection amendment.

    (a) An amended Certificate of Inspection may be issued at any time 
by any

[[Page 195]]

OCMI. The amended Certificate of Inspection replaces the original, but 
the expiration date remains the same as that of the original. An amended 
Certificate of Inspection may be issued to authorize and record a change 
in the dimensions, gross tonnage, owner, managing operator, manning, 
persons permitted, route permitted, conditions of operations, or 
equipment of a vessel, from that specified in the current Certificate of 
Inspection.
    (b) A request for an amended Certificate of Inspection must be made 
to the cognizant OCMI by the owner or managing operator of the vessel at 
any time there is a change in the character of a vessel or in its route, 
equipment, ownership, operation, or similar factors specified in its 
current Certificate of Inspection.
    (c) The OCMI may require an inspection prior to the issuance of an 
amended Certificate of Inspection.



               Subpart B_Special Permits and Certificates



Sec.  176.202  Permit to proceed.

    (a) When a vessel is not in compliance with its Certificate of 
Inspection or fails to comply with a regulation of this subchapter, the 
cognizant OCMI may permit the vessel to proceed to another port for 
repair, if in the judgment of the OCMI, the trip can be completed 
safely, even if the Certificate of Inspection of the vessel has expired 
or is about to expire.
    (b) Form CG-948, ``Permit to Proceed to another Port for Repairs,'' 
may be issued by the cognizant OCMI to the owner, managing operator, or 
the master of the vessel stating the conditions under which the vessel 
may proceed to another port. The permit may be issued only upon the 
written application of the owner, managing operator, or master, and 
after the vessel's Certificate of Inspection is turned over to the OCMI.
    (c) A vessel may not carry passengers when operating in accordance 
with a permit to proceed, unless the cognizant OCMI determines that it 
is safe to do so.

[CGD 85-080, 61 FR 953, Jan. 10, 1996, as amended by USCG-2014-0688, 79 
FR 58288, Sept. 29, 2014]



Sec.  176.204  Permit to carry excursion party.

    (a) The cognizant OCMI may permit a vessel to engage in a temporary 
excursion operation with a greater number of persons or on a more 
extended route, or both, than permitted by its Certificate of Inspection 
when, in the opinion of the OCMI, the operation can be undertaken 
safely.
    (b) Upon the written application of the owner or managing operator 
of the vessel, the cognizant OCMI may issue a Form CG-949, ``Permit To 
Carry Excursion Party,'' to indicate his or her permission to carry an 
excursion party. The OCMI will indicate on the permit the conditions 
under which it is issued, the number of persons the vessel may carry, 
the crew required, any additional lifesaving or safety equipment 
required, the route for which the permit is granted, and the dates on 
which the permit is valid.
    (c) The number of passengers normally permitted on an excursion 
vessel shall be governed by Sec.  176.113.
    (d) The OCMI will not normally waive the applicable minimum safety 
standards when issuing an excursion permit. In particular, a vessel that 
is being issued an excursion permit will normally be required to meet 
the minimum stability, survival craft, life jacket, fire safety, and 
manning standards applicable to a vessel in the service for which the 
excursion permit is requested.
    (e) The permit acts as a temporary, limited duration supplement to 
the vessel's Certificate of Inspection and must be carried with the 
Certificate of Inspection. A vessel operating under a permit to carry an 
excursion party must be in full compliance with the terms of its 
Certificate of Inspection as supplemented by the permit.
    (f) The OCMI may require an inspection prior to the issuance of a 
permit to carry an excursion party.



    Subpart C_Posting of Certificates, Permits, and Stability Letters



Sec.  176.302  Certificates and permits.

    The Certificate of Inspection and any SOLAS Certificates must be 
posted

[[Page 196]]

under glass or other suitable transparent material, such that all pages 
are visible, in a conspicuous place on the vessel where observation by 
passengers is likely. If posting is impracticable, such as in an open 
boat, the certificates must be kept on board in a weathertight container 
readily available for use by the crew and display to passengers and 
others on request.

[CGD 85-080, 61 FR 953, Jan. 10, 1996, as amended by CGD 97-057, 62 FR 
51049, Sept. 30, 1997]



Sec.  176.306  Stability letter.

    When, in accordance with Sec.  178.210 of this chapter, a vessel 
must be provided with a stability letter, the stability letter must be 
posted under glass or other suitable transparent material, such that all 
pages are visible, at the operating station of the vessel. If posting is 
impracticable, the stability letter must be kept on board in a 
weathertight container readily available for use by the crew and display 
to passengers and others on request.

                Subpart F_Hull and Tailshaft Examinations



Sec.  176.600  Drydock and internal structural examination intervals.

    (a) The owner or managing operator shall make a vessel available for 
drydock examinations, internal structural examinations, and underwater 
surveys (UWILD) required by this section.
    (b) If your vessel is operated on international voyages subject to 
SOLAS requirements, it must undergo a drydock examination once every 12 
months unless it has been approved to undergo an underwater survey 
(UWILD) per Sec.  176.615 of this part. If the vessel becomes due for a 
drydock examination or an internal structural examination during the 
voyage, it may lawfully complete the voyage prior to the examination if 
it undergoes the required examination upon completion of the voyage to 
the United States but not later than 30 days after the examination was 
due. If the vessel is due for an examination within 15 days of sailing 
on an international voyage from the United States port, it must undergo 
the required examination before sailing.
    (c) If your vessel is not operated on international voyages and does 
not meet the conditions in paragraph (d) of this section, it must 
undergo a drydock and internal structural examination as follows unless 
it has been approved to undergo an underwater survey (UWILD) per Sec.  
176.615 of this part:
    (1) A vessel that is exposed to salt water more than three months in 
any 12 month period since the last examination must undergo a drydock 
examination and an internal structural at least once every two years; 
and
    (2) A vessel that is exposed to salt water not more than three 
months in any 12 month period since the last examination must undergo a 
drydock examination and an internal structural examination at least once 
every five years.
    (d) Whenever damage or deterioration to hull plating or structural 
members that may affect the seaworthiness of a vessel is discovered or 
suspected, the cognizant OCMI may conduct an internal structural 
examination in any affected space including fuel tanks, and may require 
the vessel to be drydocked or taken out of service to assess the extent 
of the damage, and to effect permanent repairs. The OCMI may also 
decrease the drydock examination intervals to monitor the vessel's 
structural condition.
    (e) For a vessel that is eligible per Sec.  115.625, and if the 
owner opts for an alternate hull examination with the underwater survey 
portion conducted exclusively by divers, the vessel must undergo two 
alternate hull exams and two internal structural exams within any five-
year period. If a vessel completes a satisfactory alternate hull exam, 
with the underwater survey portion conducted predominantly by an 
approved underwater remotely operated vehicle (ROV), the vessel must 
undergo one alternate hull and one internal structural exam, within any 
five-year period. The vessel may undergo a drydock exam to satisfy any 
of the required alternate hull exams.

[[Page 199]]



Sec.  176.610  Scope of drydock and internal structural examinations.

    (a) A drydock examination conducted in compliance with Sec.  176.600 
must be conducted while the vessel is hauled out of the water or placed 
in a drydock or slipway. During the examination all accessible parts of 
the vessel's underwater body and all through hull fittings, including 
the hull plating and planking, appendages, propellers, shafts, bearings, 
rudders, sea chests, sea valves, and sea strainers shall be made 
available for examination. Sea chests, sea valves, and sea strainers 
must be opened for examination. On wooden vessels, fastenings may be 
required to be pulled for examination. The accuracy of draft or loading 
marks, if required by Sec.  185.602 of this chapter, must be verified if 
not verified at a previous drydock examination.
    (b) An internal structural examination conducted in compliance with 
Sec.  176.600 may be conducted while the vessel is afloat or out of the 
water and consists of a complete examination of the vessel's main 
strength members, including the major internal framing, the hull plating 
and planking, voids, and ballast, cargo, and fuel oil tanks. Where the 
internal framing, plating, or planking of the vessel is concealed, 
sections of the lining, ceiling or insulation may be removed or the 
parts otherwise probed or exposed so that the inspector may be satisfied 
as to the condition of the hull structure. Fuel oil tanks need not be 
cleaned out and internally examined if the marine inspector is able to 
determine by external examination that the general condition of the 
tanks is satisfactory.

Sec.  176.620  Description of the Alternative Hull Examination (AHE)
Program for certain passenger vessels.

    The Alternative Hull Examination (AHE) Program provides you with an 
alternative to a drydock examination by allowing your vessel's hull to 
be examined while it remains afloat. If completed using only divers, 
this program has four steps: the application process, the preliminary 
examination, the pre-survey meeting, and the hull examination. If the 
vessel is already participating in the program, or if a remotely 
operated vehicle (ROV) is used during the program, the preliminary exam 
step may be omitted. Once you complete these steps, the Officer in 
Charge, Marine Inspection (OCMI), will evaluate the results and accept 
the examination as a credit hull exam if the vessel is in satisfactory 
condition. If only divers are used for the underwater survey portion of 
the examination process, you may receive credit for a period of time 
such that subsequent AHEs would be conducted at intervals of twice in 
every five years, with no more than three years between any two AHEs. 
The OCMI may waive an underwater survey in accordance with Sec.  
176.655(d) provided that the interval does not exceed five years between 
any two underwater surveys. If an underwater ROV is used as the 
predominate method to examine the vessel's underwater hull plating, you 
may receive credit up to five years. At the end of this period, you may 
apply for further participation under the AHE Program.

    Note to Sec.  176.620: The expected hull coverage when using an ROV 
must be at least 80 percent.

Sec.  176.625  Eligibility requirements for the Alternative Hull
Examination (AHE) Program for certain passenger vessels.

    (a) Your vessel may be eligible for the AHE Program if--
    (1) It is constructed of steel or aluminum;
    (2) It has an effective hull protection system;
    (3) It has operated exclusively in fresh water since its last 
drydock examination;
    (4) It operates in rivers or protected lakes; and
    (5) It operates exclusively in shallow water or within 0.5 nautical 
miles from shore.
    (b) In addition to the requirements in paragraph (a), the Officer in 
Charge, Marine Inspection (OCMI) will evaluate the following information 
when determining your vessel's eligibility for the AHE Program:
    (1) The overall condition of the vessel, based on its inspection 
history.
    (2) The vessel's history of hull casualties and hull-related 
deficiencies.
    (3) The AHE Program application, as described in Sec.  176.630 of 
this part.
    (c) When reviewing a vessel's eligibility for the AHE program, the 
OCMI may modify the standards given by paragraph (a)(5) of this section 
where it is considered safe and reasonable to do so. In making this 
determination, the OCMI will consider the vessel's overall condition, 
its history of safe operation, and any other factors that serve to 
mitigate overall safety risks.

Sec.  176.635  Preliminary examination requirements.

    (a) If you exclusively use divers to examine the underwater hull 
plating, you must arrange to have a preliminary examination conducted by 
a third party examiner, with the assistance of qualified divers. The 
purpose of the preliminary examination is to assess the overall 
condition of the vessel's hull and identify any specific concerns to be 
addressed during the underwater hull examination.
    (b) The preliminary examination is required only upon the vessel's 
entry or reentry into the AHE program.
    (c) If you use an underwater remotely operated vehicle (ROV) as the 
predominate means to examine your vessel's hull plating, a preliminary 
examination and the participation of a third party examiner will not be 
necessary.

    (a) In advance of each AHE, you must conduct a pre-survey meeting to 
discuss the details of the AHE procedure with the Officer in Charge, 
Marine Inspection (OCMI). If you exclusively use divers to examine the 
underwater hull plating, the third party examiner must attend the 
meeting and you must present the results of the preliminary examination. 
If you use an underwater remotely operated vehicle (ROV) as the 
predominate means to examine the vessel's hull plating, then the pre-
survey meeting must be attended by a representative of the ROV operating 
company who is qualified to discuss the ROV's capabilities and 
limitations related to your vessel's hull design and configuration.
    (b) A vessel owner, operator, or designated agent must request this

Sec.  176.645  AHE Procedure.

    (a) To complete the underwater survey you must--
    (1) Perform a general examination of the underwater hull plating and 
a detailed examination of all hull welds, propellers, tailshafts, 
rudders, and other hull appurtenances;
    (2) Examine all sea chests;
    (3) Remove and inspect all sea valves in the presence of a marine 
inspector once every five years;
    (4) Remove all passengers from the vessel when the sea valves are 
being examined, if required by the Officer in Charge, Marine Inspection 
(OCMI);
    (5) Allow access to all internal areas of the hull for examination, 
except internal tanks that carry fuel (unless damage or deterioration is 
discovered or suspect), sewage, or potable water. Internal sewage and 
potable water tanks may be examined visually or by non-destructive 
testing to the satisfaction of the attending marine inspector; and
    (6) Meet the requirements in Sec.  176.650 of this part.
    (b) A marine inspector may examine any other areas deemed necessary 
by the OCMI.
    (c) If the AHE reveals significant deterioration or damage to the 
vessel's hull plating or structural members, the OCMI must be 
immediately notified. The OCMI may require the vessel be drydocked or 
otherwise taken out of service to further assess the extent of damage or 
to effect permanent repairs if the assessment or repairs cannot be

[[Page 202]]

completed to the satisfaction of the OCMI while the vessel is 
waterborne.

Aug. 5, 2004]



Sec.  176.650  Alternative Hull Examination Program options: Divers or
underwater ROV.

    To complete the underwater survey portion of the AHE, you may use 
divers or an underwater remotely operated vehicle (ROV).
    (a) If you use divers to conduct the underwater survey, you must--
    (1) Locate the vessel so the divers can work safely under the 
vessel's keel and around both sides. The water velocity must be safe for 
dive operations;
    (2) Provide permanent hull markings, a temporary grid system of 
wires or cables spaced not more than 10 feet apart and tagged at one-
foot intervals, or any other acoustic or electronic positioning system 
approved by the OCMI to identify the diver's location with respect to 
the hull, within one foot of accuracy;
    (3) Take ultrasonic thickness gaugings at a minimum of 5 points on 
each plate, evenly spaced;
    (4) Take hull plating thickness gaugings along transverse belts at 
the bow, stern, and midships, as a minimum. Plating thickness gaugings 
must also be taken along a longitudinal belt at the wind and water 
strake. Individual gaugings along the transverse and longitudinal belts 
must be spaced no more than 3 feet apart;
    (5) Ensure the third party examiner observes the entire underwater 
examination process;
    (6) Record the entire underwater survey with audio and video 
recording equipment and ensure that communications between divers and 
the third party examiner are recorded; and
    (7) Use appropriate equipment, such as a clear box, if underwater 
visibility is poor, to provide the camera with a clear view of the hull.
    (b) You may use an underwater ROV to conduct the underwater survey. 
The underwater ROV operating team, survey process and equipment, quality 
assurance methods, and the content and format of the survey report must 
be accepted by the Officer in Charge, Marine Inspection (OCMI) prior to 
the survey. If you choose this option, you must--
    (1) Locate the vessel to ensure that the underwater ROV can operate 
effectively under the vessel's keel and around both sides; and
    (2) Employ divers to examine any sections of the hull and 
appurtenances that the underwater ROV cannot access or is otherwise 
unable to evaluate.
    (3) If the OCMI determines that the data obtained by the ROV, 
including non-destructive testing results, readability of the results, 
and positioning standards, will not integrate into the data obtained by 
the divers, then a third party examiner must be present during the 
divers portion of the examination.

[USCG-2000-6858, 67 FR 21086, Apr. 29, 2002, as amended at 69 FR 47384,

Sec.  176.655  Hull examination reports.

    (a) If you use only divers for the underwater survey portion of the 
Alternative Hull Examination (AHE), you must provide the Officer in 
Charge, Marine Inspection (OCMI), with a written hull examination 
report. This report must include thickness gauging results, bearing 
clearances, a copy of the audio and video recordings, and any other 
information that will help the OCMI evaluate your vessel for a credit 
hull exam. The third party examiner must sign the report and confirm the 
validity of its contents.
    (b) If you use an underwater remotely operated vehicle (ROV) as the 
predominate means to examine the vessel's underwater hull plating, you 
must provide the OCMI with a report in a format that is acceptable to 
the OCMI, per Sec.  176.650(b) of this part.
    (c) The OCMI will evaluate the hull examination report and grant a 
credit hull exam if satisfied with the condition of the vessel. If 
approved and you exclusively use divers to examine the hull plating, you 
will receive a credit hull exam of up to 36 months. (Underwater 
examinations are required twice every 5 years.) If approved and you use 
an underwater ROV as the predominate means to examine the hull plating, 
you will receive a credit hull exam of up to 60 months (5 years).

[[Page 203]]

    (d) At least 60 days prior to each scheduled underwater exam, the

Sec.  176.660  Continued participation in the Alternative Hull Examination 
(AHE) Program.

    (a) To continue to participate in the AHE Program, vessel operators 
must conduct an annual hull condition assessment. At a minimum, vessel 
operators must conduct an internal examination and take random hull 
gaugings internally during the hull condition assessment, unless waived 
by the Officer in Charge, Marine Inspection (OCMI). If the annual hull 
assessment reveals significant damage or corrosion, where temporary 
repairs have been made, or where other critical areas of concern have 
been identified, the OCMI may require an expanded examination to include 
an underwater hull examination using divers. If an underwater 
examination is required, the examination must focus on areas at higher 
risk of damage or corrosion and must include a representative sampling 
of hull gaugings.
    (b) If an underwater survey is required for the annual hull 
condition assessment, the OCMI may require the presence of a third party 
examiner and a written hull examination report must be submitted to the 
OCMI. This report must include thickness gauging results, a copy of the 
audio and video recordings and any other information that will help the 
OCMI evaluate your vessel for continued participation in the AHE 
program. The third party examiner must sign the report and confirm the 
validity of its contents.
    (c) You must submit your preventive maintenance reports or 
checklists on an annual basis to the OCMI. These reports or checklists 
must conform to the plans you submitted in your application under Sec.  
176.630 of this part, which the OCMI approved.
    (d) Prior to each scheduled annual hull condition assessment--
    (1) The owner may submit to the OCMI a plan for conducting the 
assessment, or a request for a waiver of this requirement, no fewer than 
30 days before the scheduled assessment; and
    (2) The OCMI may reduce the scope or extend the interval of the 
assessment if the operational, casualty, and deficiency history of the 
vessel, along with a recommendation of the vessel's master, indicates 
that it is warranted.

                      Subpart E_Escape Requirements



Sec.  177.500  Means of escape.

    (a) Except as otherwise provided in this section, each space 
accessible to passengers or used by the crew on a regular basis, must 
have at least two means of escape, one of which must not be a watertight 
door.
    (b) The two required means of escape must be widely separated and, 
if possible, at opposite ends or sides of the space to minimize the 
possibility of one incident blocking both escapes.
    (c) Subject to the restrictions of this section, means of escape may 
include normal exits and emergency exits, passageways, stairways, 
ladders, deck scuttles, and windows.
    (d) The number and dimensions of the means of escape from each space 
must be sufficient for rapid evacuation in an emergency for the number 
of persons served. In determining the number of persons served, a space 
must be considered to contain at least the number of persons as follows:
    (1) Passenger overnight accommodation spaces: Designed capacity;
    (2) Accommodation spaces having fixed seating for passengers: 
Maximum seating capacity;
    (3) Public spaces, including spaces such as casinos, restaurants, 
club rooms, and cinemas, and public accommodation spaces as defined in 
Sec.  175.400 of this subchapter, except overnight accommodation spaces: 
One person may be permitted for each 0.9 square meters (10 square feet) 
of deck area. In computing such deck area, the following areas must be 
excluded:
    (i) Areas for which the number of persons permitted is determined 
using the fixed seating criterion;
    (ii) Obstructions, including stairway and elevator enclosures, 
elevated stages, bars, and cashier stands, but not including slot 
machines, tables, or other room furnishings;

protrusions in means of escape that could cause injury, ensnare 
clothing, or damage life jackets.
    (f) The minimum clear opening of a door or passageway used as a 
means of escape must not be less than 810 millimeters (32 inches) in 
width, however, doors or passageways used solely by crew members must 
have a clear opening not less than 710 millimeters (28 inches). The sum 
of the width of all doors and passageways used as means of escape from a 
space must not be less than 8.4 millimeters (0.333 inches) multiplied by 
the number of passengers for which the space is designed.

[[Page 217]]

    (g) A dead end passageway, or the equivalent, of more than 6.1 
meters (20 feet) in length is prohibited.
    (h) Each door, hatch, or scuttle, used as a means of escape, must be 
capable of being opened by one person, from either side, in both light 
and dark conditions. The method of opening a means of escape must be 
obvious, rapid, and of adequate strength. Handles and securing devices 
must be permanently installed and not capable of being easily removed. A 
door, hatch or scuttle must open towards the expected direction of 
escape from the space served.
    (i) A means of escape which is not readily apparent to a person from 
both inside and outside the space must be adequately marked in 
accordance with Sec.  185.606 of this chapter.
    (j) A ladder leading to a deck scuttle may not be used as a means of 
escape except:

accommodation space or work space.
    (k) Each ladder used as a means of escape must be mounted at least 
180 millimeters (7 inches) from the nearest permanent object in back of 
the ladder. Rungs must be:
    (1) At least 405 millimeters (16 inches) in width; and
    (2) Not more than 305 millimeters (12 inches) apart, and uniformly 
spaced for the length of the ladder with at least 114 millimeters (4.5 
inches) clearance above each rung.
    (l) When a deck scuttle serves as a means of escape, it must not be 
less than 455 millimeters (18 inches) in diameter and must be fitted 
with a quick acting release and a holdback device to hold the scuttle in 
an open position.
    (m) Footholds, handholds, ladders, and similar means provided to aid 
escape, must be suitable for use in emergency conditions, of rigid 
construction, and permanently fixed in position, unless they can be 
folded, yet brought into immediate service in an emergency.
    (n) Vessels described by 46 CFR 175.110(d) must ensure that the two 
means of escape required in paragraph (b) of this section are 
unobstructed and the door, hatch, or scuttle is not located directly 
above, or dependent on, a berth.
    (o) On a vessel of not more than 19.8 meters (65 feet) in length, a 
window or windshield of sufficient size and proper accessibility may be 
used as one of the required means of escape from an enclosed space, 
provided it:
    (1) Does not lead directly overboard;
    (2) Can be opened or is designed to be kicked or pushed out; and
    (3) Is suitably marked.
    (p) Only one means of escape is required from a space where:
    (1) The space has a deck area less than 30 square meters (322 square 
feet);
    (2) There is no stove, heater, or other source of fire in the space;
    (3) The means of escape is located as far as possible from a 
machinery space or fuel tank; and
    (4) If an accommodation space, the single means of escape does not 
include a deck scuttle or a ladder.
    (q) Alternative means of escape from spaces may be provided if 
acceptable to the cognizant OCMI.

writing, weight and vertical center of gravity are to be assumed as 
follows:
    (i) The weight of primary lifesaving equipment should be simulated 
at its normal location, if not on board at the time of the test.
    (ii) The assumed weight per person is determined as provided by 
Sec.  170.090 of this chapter.
    (iii) The weight and associated vertical center of gravity of 
variable loads must be included as appropriate for the service intended 
and documented in the stability information required by subpart B of 
this part.
    (iv) The vertical center for the total test weight must be at least 
30 inches (760 millimeters) above the deck for seated passengers, and at 
least 39 inches (1.0 meter) above the deck for standing passengers.
    (v) If the vessel carries passengers on diving excursions, the total 
weight of diving gear must be included in the loaded condition and 
placed in its stowed position. Not less than 80 pounds (36.3 kilograms) 
should be assumed for each person for whom diving gear is provided.
    (vi) On vessels having one upper deck available to passengers above 
the main deck, the weight distribution must not be less severe than the 
following:

Total Test Weight (W) = ________
Passenger Capacity of Upper Deck:
________________________________________________________________________

[[Page 225]]

Weight on Upper Deck = (Number of Passengers on Upper Deck) * (Wt per 
          Passenger) * 1.33
Weight on Main Deck = Total Test Weight-Weight on Upper Deck.

    (5) All non-return closures on cockpit scuppers or on weather deck 
drains must be kept open during the test.
    (b) A vessel must not exceed the limitations in paragraph (d) of 
this section, when subjected to the greater of the following heeling 
moments:
Mp = (W) (Bp)/6; or
Mw = (P) (A) (H)

Where:
Mp = passenger heeling moment in foot-pounds (kilogram-
          meters);
Mw = Wind heeling moment in foot-pounds (kilogram-meters)
W = the total weight of persons other than required crew, plus the 
          personal effects of those persons expected to be carried while 
          aboard the vessel (total test weight) in pounds (meters);
Bp = the maximum transverse distance in feet (meters) of a 
          deck that is accessible to passengers;
A = Area, in square feet (square meters), of the projected lateral 
          surface of the vessel above the waterline (including each 
          projected area of the hull, superstructure, cargo, masts, area 
          bounded by railings and canopies, but not protruding fixed 
          objects such as antennas or running rigging).

    (c) For sailing vessels the heeling moment used for this test must 
be the greater of the following:
    (1) Passenger heeling moment from paragraph (b) of this section.
    (2) Wind heeling moment from paragraph (b) of this section.
    (3) Wind heeling moment calculated from the wind heeling moment 
equation in paragraph (b) of this section, where:

Mw = wind heeling moment in kilogram-meters (foot-pounds);
P = 4.9 kilograms/square meter (1.0 pounds/square foot) for both 
          protected and partially protected waters.
A = the windage area of the vessel in square meters (square feet) with 
          all sails set and trimmed flat;

    (1) On a flush deck vessel, not more than one-half of the freeboard 
may be immersed.
    (2) On a well deck vessel, not more than one-half of the freeboard 
may be immersed, except that, on a well deck vessel that operates on 
protected waters and has non-return scuppers or freeing ports, the full 
freeboard may be immersed if the full freeboard is not more than one-
quarter of the distance from the waterline to the gunwale.
    (3) On a cockpit vessel, the maximum allowable immersion is 
calculated from the following equation:
    (i) On exposed waters--

i = f(2L-1.5L')/4L

    (ii) On protected or partially protected waters--

i = f(2L-L')/4L

where:

i = maximum allowable immersion in meters (feet);
f = freeboard in meters (feet);
L = length of the weather deck, in meters (feet); and
L' = length of cockpit in meters (feet).

    (4) On an open boat, not more than one quarter of the freeboard may 
be immersed.
    (5) On a flush deck sailing vessel, the full freeboard may be 
immersed.
    (6) On a non-sailing flush deck catamaran that is propelled by 
mechanical means, not more than one-third of the freeboard or one-third 
of the draft, whichever is less, may be immersed.
    (7) In no case may the angle of heel exceed 14 degrees.
    (e) The limits of heel must be measured at:
    (1) The point of minimum freeboard; or
    (2) At a point three-quarters of the vessel's length from the bow if 
the point of minimum freeboard is aft of this point.
    (f) When demonstrating compliance with paragraph (d) of this 
section, the freeboard must be measured as follows:
    (1) For a flush deck or well deck vessel, the freeboard must be 
measured to the top of the weatherdeck at the side of the vessel; and
    (2) For a cockpit vessel or for an open boat, the freeboard must be 
measured to the top of the gunwale.
    (g) A ferry must also be tested in a manner acceptable to the 
cognizant

[[Page 226]]

OCMI to determine whether the trim or heel during loading or unloading 
will submerge the deck edge. A ferry passes this test if, with the total 
number of passengers and the maximum vehicle weight permitted on board, 
the deck edge is not submerged during loading or unloading of the 
vessel.

               Subpart E_Number and Type of Survival Craft



Sec.  180.200  Survival craft--general.

    (a) Each survival craft required on a vessel by this part must meet 
one of the following:
    (1) For an inflatable liferaft--Approved under approval series 
160.151 or other standard specified by the Commandant, with the 
applicable equipment pack, as determined by the cognizant OCMI. Each 
inflatable liferaft required on a vessel by this part must have a 
capacity of 6 persons or more. Inflatable liferafts may be substituted 
for inflatable buoyant apparatus or life floats required under this 
section;
    (2) For a life float--Approved under approval series 160.027 or 
other standard specified by the Commandant. Buoyant apparatus may be 
used to meet requirements for life floats if the buoyant apparatus was 
installed on board the vessel on or before March 11, 1996, and if the 
buoyant apparatus remains in good and serviceable condition;
    (3) For an inflatable buoyant apparatus--Approved under approval 
series 160.010 or other standard specified by the Commandant. Inflatable 
buoyant apparatus may be substituted for life floats required under this 
section.
    (4) For a buoyant apparatus--Approved under approval series 160.010 
or other standard specified by the Commandant. An existing buoyant 
apparatus may not be used to satisfy the requirements for life floats on 
existing vessels wishing to upgrade the total number of passengers 
carried on an oceans route.
    (b) If the vessel carries a small boat or boats, the capacity of 
these boats may be counted toward life float capacity required by this 
part. Such boats must meet the requirements for safe loading and 
flotation in 33 CFR part 183, and must meet the stowage, launching, and 
equipment requirements in this part for the survival craft they replace.
    (c) A summary of survival craft requirements is provided in Table 
180.200(c).

be tested, as required by this paragraph, upon completion of the piping 
installation, using only carbon dioxide, compressed air, or nitrogen.
    (i) When pressurizing the piping, pressure must be increased in 
small increments. Each joint must be subjected

[[Page 253]]

to a soap bubble leak test, and all joints must be leak free.
    (ii) Piping between the storage cylinders and the manifold stop 
valve must be subjected to a leak test conducted at a pressure of 4,136 
kPa (600 psi). Without additional gas being added to the system, there 
must be no loss of pressure over a two minute period after thermal 
equilibrium is reached.
    (iii) Distribution piping between the manifold stop valve and the 
first nozzle in the system must be capped and pneumatically tested for a 
period of 10 minutes at 1,034 kPa (150 psi). At the end of 10 minutes, 
the pressure drop must not exceed 10% of the test pressure.
    (e) Pressure relief. When required by the cognizant OCMI, spaces 
that are protected by a fixed gas fire extinguishing system and that are 
relatively air tight, such as refrigeration spaces, paint lockers, etc., 
must be provided with suitable means for relieving excessive pressure 
within the space when the agent is released.
    (f) Specific requirements for carbon dioxide systems. A custom 
engineered fixed gas fire extinguishing system, which uses carbon 
dioxide as the extinguishing agent, must meet the requirements of this 
paragraph.
    (1) Piping, valves, and fittings must have a bursting pressure of 
not less than 41,360 kPa (6,000 psi). Piping, in nominal sizes of not 
more than 19 millimeters (0.75 inches), must be at least Schedule 40 
(standard weight), and in nominal sizes of over 19 millimeters (0.75 
inches), must be at least Schedule 80 (extra heavy).
    (2) A pressure relief valve or equivalent set to relieve at between 
16,550 and 19,300 kPa (2,400 and 2,800 psi) must be installed in the 
distribution manifold to protect the piping from over-pressurization.
    (3) Nozzles must be approved by the Commandant.
    (4) When installed in a machinery space, paint locker, a space 
containing flammable liquid stores, or a space with a fuel tank, a fixed 
carbon dioxide system must meet the following requirements.
    (i) The quantity of carbon dioxide in kilograms (pounds) that the 
system must be capable of providing to a space must not be less than the 
gross volume of the space divided by the appropriate factor given in 
Table 181.410(f)(4)(i). If fuel can drain from a space being protected 
to an adjacent space or if the spaces are not entirely separate, the 
volume of both spaces must be used to determine the quantity of carbon 
dioxide to be provided. The carbon dioxide must be arranged to discharge 
into both such spaces simultaneously.

    (iv) The number, type, and location of discharge outlets must 
provide uniform distribution of carbon dioxide throughout a space.
    (v) The total area of all discharge outlets must not exceed 85 
percent nor be less than 35 percent of the nominal cylinder outlet area 
or the area of the supply pipe, whichever is smaller. The nominal 
cylinder outlet area in square millimeters (inches) is determined by 
multiplying the factor 0.015 (0.0022 if

[[Page 254]]

using square inches) by the total capacity in kilograms (pounds) of all 
carbon dioxide cylinders in the system, except in no case must the 
outlet area be of less than 71 square millimeters (0.110 square inches 
if using pounds).
    (vi) The discharge of at least 85 percent of the required amount of 
carbon dioxide must be completed within two minutes.
    (5) When installed in an enclosed ventilation system for rotating 
electrical propulsion equipment a fixed carbon dioxide extinguishing 
system must meet the following requirements.
    (i) The quantity of carbon dioxide in kilograms (pounds) must be 
sufficient for initial and delayed discharges as required by this 
paragraph. The initial discharge must be equal to the gross volume of 
the system in cubic meters divided by 0.624 (10 if using pounds) for 
ventilation systems having a volume of less than 57 cubic meters (2,000 
cubic feet), or divided by 0.749 (12 if using pounds) for ventilation 
systems having a volume of at least 57 cubic meters (2,000 cubic feet). 
In addition, there must be sufficient carbon dioxide available to permit 
delayed discharges to maintain at least a 25 percent concentration until 
the equipment can be stopped. If the initial discharge achieves this 
concentration, a delayed discharge is not required.
    (ii) The piping sizes for the initial discharge must be in 
accordance with Table 181.410(f)(4)(ii) and the discharge of the 
required amount must be completed within two minutes.
    (iii) Piping for the delayed discharge must not be less than 12.7 
millimeters (0.5 inches) nominal pipe size, and need not meet specific 
requirement for discharge rate.
    (iv) Piping for the delayed discharge may be incorporated with the 
initial discharge piping.
    (6) When installed in a cargo space a fixed carbon dioxide 
extinguishing system must meet the following requirements.
    (i) The number of kilograms (pounds) of carbon dioxide required for 
each space in cubic meters (feet) must be equal to the gross volume of 
the space in cubic meters (feet) divided by 1.88 (30 if using pounds).
    (ii) System piping must be of at least 19 millimeters (0.75 inches).
    (iii) No specific discharge rate is required.
    (7) A lockout valve must be provided on any carbon dioxide 
extinguishing system protecting a space over 6,000 cubic feet in volume 
and installed or altered after [July 9, 2013. ``Altered'' means modified 
or refurbished beyond the maintenance required by the manufacturer's 
design, installation, operation and maintenance manual.
    (i) The lockout valve must be a manually operated valve located in 
the discharge manifold prior to the stop valve or selector valves. When 
in the closed position, the lockout valve must provide complete 
isolation of the system from the protected space or spaces, making it 
impossible for carbon dioxide to discharge in the event of equipment 
failure during maintenance.
    (ii) The lockout valve design or locking mechanism must make it 
obvious whether the valve is open or closed.
    (iii) A valve is considered a lockout valve if it has a hasp or 
other means of attachment to which, or through which, a lock can be 
affixed, or it has a locking mechanism built into it.
    (iv) The master or person-in-charge must ensure that the valve is 
locked open at all times, except while maintenance is being performed on 
the extinguishing system, when the valve must be locked in the closed 
position.
    (v) Lockout valves added to existing systems must be approved by the 
Commandant as part of the installed system.
    (8) Each carbon dioxide extinguishing system installed or altered 
after July 9, 2013, must have an approved odorizing unit to produce the 
scent of wintergreen, the detection of which will serve as an indication 
that carbon dioxide gas is present in a protected area and any other 
area into which the carbon dioxide may migrate. ``Altered'' means 
modified or refurbished beyond the maintenance required by the 
manufacturer's design, installation, operation and maintenance manual.
    (g) Specific requirements for Halon 1301 systems. (1) A custom 
engineering fixed gas fire extinguishing system, which uses Halon 1301, 
must comply with the

[[Page 255]]

applicable sections of UL 1058 (incorporated by reference, see 46 CFR 
175.600) and the requirements of this paragraph (g).
    (2) The Halon 1301 quantity and discharge requirements of UL 1058 
apply, with the exception that the Halon 1301 design concentration must 
be 6 percent at the lowest ambient temperature expected in the space. If 
the lowest temperature is not known, a temperature of -18 [deg]C (0 
[deg]F) must be assumed.
    (3) Each storage cylinder in a system must have the same pressure 
and volume.
    (4) Computer programs used in designing systems must have been 
approved by an independent laboratory.

    Note to Sec.  181.410(g): As of Jan. 1, 1994, the United States 
banned the production of Halon. The Environmental Protection Agency 
placed significant restrictions on the servicing and maintenance of 
systems containing Halon. Vessels operating on an international voyage, 
subject to SOLAS requirements, are prohibited from installing fixed gas 
fire extinguishing systems containing Halon.

    (d) In systems and applications where flexible hoses are permitted 
to be clamped:
    (1) Double hose clamping is required where practicable;
    (2) The clamps must be of a corrosion resistant metallic material;
    (3) The clamps must not depend on spring tension for their holding 
power; and
    (4) Two clamps must be used on each end of the hose, or one hose 
clamp can be used if the pipe ends are expanded or beaded to provide a 
positive stop against hose slippage.



Sec.  182.415  Carburetors.

    (a) All carburetors except the downdraft type must be equipped with 
integral or externally fitted drip collectors of adequate capacity and 
arranged so as to permit ready removal of fuel leakage. Externally 
fitted drip collectors, must be covered with flame screens. Drip 
collectors, where practicable, should automatically drain back to engine 
air intakes.
    (b) All gasoline engines installed in a vessel, except outboard 
engines, must be equipped with an acceptable means of backfire flame 
control. Installation of backfire flame arresters bearing basic Approval 
Numbers 162.015 or 162.041 or engine air and fuel induction systems 
bearing basic Approval Numbers 162.042 or 162.043 may be continued in 
use as long as they are serviceable and in good condition. New 
installations or replacements must meet the applicable requirements of 
this section.

hydrostatically tested to, and must withstand, a pressure of 35 kPa (5 
psig) or 11/2 times the maximum pressure head to which they may be 
subjected in service, whichever is greater. A standpipe of 3.5 meters 
(11.5 feet) in height attached to the tank may be filled with water to 
accomplish the 35 kPa (5 psig) test. Permanent deformation of the tank 
will not be cause for rejection unless accompanied by leakage.
    (2) After installation of the fuel tank on a vessel, the complete 
installation must be tested in the presence of a marine inspector, or 
individual specified by the cognizant OCMI, to a heat not less than that 
to which the tank may be subjected in service. Fuel may be used as the 
testing medium.

handling gear designated for this use shall meet the applicable portions 
of Subchapter I (Cargo and Miscellaneous Vessels) of this chapter.
    (b) Weight handling gear placed under the inspection and testing 
required for cargo gear by the classification society or cargo gear 
bureaus recognized in Subchapter I (Cargo and Miscellaneous Vessels) of 
this chapter may be considered as having met the intent of this subpart.



Sec.  189.35-3  Intent.

    (a) In recognition of the special nature of oceanographic research 
vessel operations, it is intended that maximum flexibility be given to 
the owner or operator in complying with the safety requirements for 
weight handling gear in this subpart. The primary interest of the Coast 
Guard shall extend to hazards associated with the connections to the 
vessel, dangerous moving parts, extremes in temperature and shock 
hazards.



Sec.  189.35-5  Tests.

    (a) An installation load test and safety assessment shall be 
conducted by the owner or operator. Section 189.35-13 may be used as a 
guide for the safety assessment. It shall be the responsibility of the 
owner or operator to notify the Officer in Charge, Marine Inspection, of 
the time and place of the installation tests when occurring in a port of 
the United States to permit a marine inspector to witness the tests if 
desired. Subsequent owner or operator conducted tests may be required at 
the time of the vessel's inspection periods if a visual examination or 
review of the equipment record reveals evidence of an unsafe condition. 
Tests should normally consist of exercising the equipment as a unit with 
a proof load 25 percent in excess of the equipment's normal working 
load, however manufacturer's design limitations should not be exceeded. 
Consideration shall be given to the plans of loading when conducting 
these tests. Braking, safety and limiting devices shall be tested 
whenever feasible.



Sec.  189.35-7  Examinations.

    (a) Examination of weight handling gear will normally consist of a 
visual examination with access covers removed. Suitability of the 
equipment for the service intended will be emphasized. Disassembly of 
the equipment will be required only when there is evidence of a 
deficiency or an unsafe condition. Non-destructive tests, such as 
radiography, ultrasonic, electronic, or other methods may be used if 
appropriate, however will not be required.



Sec.  189.35-9  Plans.

    (a) Plans will not normally be required, however depending on the 
use of the weight handling gear, submission of plans or other technical 
information may be required by the Officer in Charge, Marine Inspection. 
Unless an unsafe condition is in evidence, vessel operations will not be 
delayed while plans or other technical information are under review. 
Plans, when required, shall normally include:
    (1) One line electrical diagrams showing appropriate overload 
protection as currently required by subchapter J (Electrical 
Engineering) of this chapter.
    (2) Plans showing hydraulic or pneumatic equipment.
    (3) Stress and/or arrangement diagrams with supporting design 
calculations as appropriate to the specific equipment in question.

[[Page 323]]

    (b) When weight handling gear is built to a recognized code or 
specification, plans or other technical data will not normally be 
required. Purchase specification or vendor's information may be accepted 
in lieu of design calculations if sufficiently definitive of materials, 
design (safety) factors and operating limitations.
    (c) Design information, when required, will be evaluated against the 
following minimum design criteria:
    (1) Wet Weight Handling Gear: Wet gear shall be considered to 
consist of gear used to lower equipment, apparatus or objects beneath 
the surface of the water or for trailing objects, where the wire rope or 
cable is payed out beneath the surface and becomes part of the line pull 
at the head sheave or winch drum. Wet gear shall be designed, as a 
minimum, to withstand and operate in excess of the breaking strength of 
the strongest section or wire to be used in any condition of loading. 
The safety factor for all metal structural parts shall be a minimum of 
1.5; i.e., the yield strength of the material shall be at least 1.5 
times the calculated stresses resulting from application of a load equal 
to the nominal breaking strength of the strongest section or wire rope 
to be used. Suitable assumptions for the actual loading conditions shall 
be used in the design of wet gear. The lead of the wire rope from the 
head sheave or winch drum shall be considered to vary from the vertical 
and in azimuth in a manner to represent the most adverse loading 
condition.
    (2) Other weight handling gear will be evaluated on the basis of the 
standards of a recognized organization or association recognized by the 
Commandant under Sec.  31.10-6.
    (3) Hydraulic or pneumatic systems will be evaluated on the basis of 
Subchapter F (Marine Engineering) of this chapter.

appurtenances connected to such fuel tanks.
    (c) Such inspections shall be made and evidenced as follows:
    (1) In ports or places in the United States or its territories and 
possessions the inspection shall be made by a marine chemist 
certificated by the National Fire Protection Association; however, if 
the services of such certified marine chemist are not reasonably 
available, the Officer in Charge, Marine Inspection, upon the 
recommendation of the vessel owner and his contractor or their 
representative shall select a person who, in the case of an individual 
vessel, shall be authorized to make such inspection. If the inspection 
indicates that such operations can be undertaken with safety, a 
certificate setting forth the fact in writing and qualified as may be 
required, shall be issued by the certified marine chemist or the 
authorized person before the work is started. Such qualifications shall 
include any requirements as may be deemed necessary to maintain, insofar 
as can reasonably be done, the safe conditions in the spaces certified 
throughout the operation and shall include such additional tests and 
certifications as considered required. Such qualifications and 
requirements shall include precautions necessary to eliminate or 
minimize hazards that may be present from protective coatings or 
residues from cargoes.
    (2) When not in such a port or place, and a marine chemist or such 
person authorized by the Officer in Charge, Marine Inspection, is not 
reasonably available, the inspection shall be made by the senior officer 
in the crew present and a proper entry shall be made in the vessel's 
logbook.
    (d) It shall be the responsibility of the senior officer present to 
secure copies of certificates issued by the certified marine chemist or 
such person authorized by the Officer in Charge, Marine Inspection. It 
shall be the responsibility of the senior officer in the crew present,

procedures would apply, but in a particular case, if a more expeditious 
procedure can be used, there will be no objection to its adoption.
    (1) The plans may be submitted to the Officer in Charge, Marine 
Inspection, in the district in which the vessel is to be built. This 
procedure will be most expeditious in the case of those offices where 
personnel and facilities are available for examination and approval of 
plans locally.
    (2) The plans may be submitted by visitors directly to the 
Commanding Officer, Marine Safety Center, U.S. Coast Guard, 2703 Martin 
Luther King Jr. Avenue SE., Washington, DC 20593, or transmitted by mail 
to: Commanding Officer (MSC), Attn: Marine Safety Center, U.S. Coast 
Guard Stop 7430, 2703 Martin Luther King Jr. Avenue SE., Washington, DC 
20593-7430, in a written or electronic format. Information for 
submitting the VSP electronically can be found at http://www.uscg.mil /
HQ/MSC. In this case, the plans will be returned directly to the 
submitter, with a copy of the action being forwarded to the interested 
Officer in Charge, Marine Inspection.
    (3) In the case of classed vessels, upon specific request by the 
submitter, the American Bureau of Shipping will arrange to forward the 
necessary plans to the Coast Guard indicating its action thereon. In 
this case, the plans will be returned as noted in paragraph (a)(2) of 
this section.

extends over an arc from at least 22.5 degrees abaft the beam on one 
side of the vessel, through dead ahead, to at least 22.5 degrees abaft 
the beam on the other side of the vessel. Blind sectors forward of the 
beam caused by cargo, cargo gear, or other permanent obstruction must 
not exceed 10 degrees each, nor total more than 20 degrees, including 
any blind sector within the arc of visibility described in paragraph 
(a)(1) of this section.
    (3) From each bridge wing, the field of vision extends over an arc 
from at

[[Page 332]]

least 45 degrees on the opposite bow, through dead ahead, to at least 
dead astern.
    (4) From the main steering position, the field of vision extends 
over an arc from dead ahead to at least 60 degrees on either side of the 
vessel.
    (5) From each bridge wing, the respective side of the vessel is 
visible forward and aft.
    (b) Windows fitted on the navigation bridge must be arranged so 
that:
    (1) Framing between windows is kept to a minimum and is not 
installed immediately in front of any work station.
    (2) Front windows are inclined from the vertical plane, top out, at 
an angle of not less than 10 degrees and not more than 25 degrees.
    (3) The height of the lower edge of the front windows is limited to 
prevent any obstruction of the forward view previously described in this 
section.
    (4) The height of the upper edge of the front windows allows a 
forward view of the horizon at the conning position, for a person with a 
height of eye of 1.8 meters (71 inches), when the vessel is at a forward 
pitch angle of 20 degrees.
    (c) Polarized or tinted windows must not be fitted.

admission of insects.



Sec.  190.20-90  Vessels contracted for prior to March 1, 1968.

    Existing structures, arrangements, materials, and facilities 
previously approved will be considered satisfactory so long as they are 
maintained in good condition to the satisfaction of the Officer in 
Charge, Marine Inspection. Minor repairs and alterations may be made to 
the same standards as the original construction, provided that in no 
case will a greater departure from the standards of Sec. Sec.  190.20-5 
through 190.20-55 be permitted than presently exists.



                     Subpart 190.25_Rails and Guards



Sec.  190.25-1  Application.

    (a) The provisions of this subpart with the exception of Sec.  
190.25-90, apply to all vessels contracted for on or after July 1, 1969.
    (b) Vessels contracted for prior to July 1, 1969 shall meet the 
requirements of Sec.  190.25-90.

[CGFR 69-72, 34 FR 17503, Oct. 29, 1969]



Sec.  190.25-5  Where rails required.

    (a) All vessels shall have efficient guard rails or bulwarks on 
decks and bridges. The height of rails or bulwarks shall be at least 
39\1/2\ inches from the deck. At exposed peripheries of the freeboard 
and superstructure decks, the rails shall be in at least three courses, 
including the top. The opening below the lowest course shall not be more 
than 9 inches. The courses shall not be more than 15 inches apart. In 
the case of ships with rounded gunwales the guard rail supports shall be 
placed in the flat of the deck. On other decks and bridges the rails 
shall be in at least two courses, including the top, approximately 
evenly spaced. If it can be shown to the satisfaction of the Officer in 
Charge, Marine Inspection, that the installation of rails of such height 
will be unreasonable and impracticable, having regard to the business of 
the vessel, rails of a lesser height or in some cases grab rails may be 
accepted and inboard rails may be eliminated if the deck is not 
generally accessible.
    (b) Where it can be shown to the satisfaction of the Commandant that 
a vessel is engaged exclusively in voyages of a sheltered nature, the 
provisions of paragraph (a) of this section may be relaxed.

----------------------------------------------------------------------------------------------------------------
\1\ On vessels of 65 feet (19.8 meters) in length or less, \3/4\ inch hose of good commercial grade together
  with a commercial garden hose nozzle may be used. The pump may be hand operated and the length of hose must be
  sufficient to assure coverage of all parts of the vessel.
\2\ 75 feet (22.86 meters) of 1\1/2\ inch hose and \5/8\ inch nozzle may be used where specified by Sec.
  193.10-10(b) for interior locations and 50 feet (15.24 meters) of 1\1/2\ inch hose may be used in exterior
  locations on vessels in other than ocean or coastwise services. Vessels on ocean or coastwise services may
  substitute two 1\1/2\ inch outlets with two 1\1/2\ inch hoses supplied through a wye connection in exterior
  locations.

    (b) On vessels of 1,000 gross tons or more on an international 
voyage, each required fire pump, while delivering water through the fire 
main system at a pressure corresponding to that required by paragraph 
(c) of this section, must have a minimum capacity of at least two-thirds 
of that required for an independent bilge pump. However, in no case 
shall the capacity of each fire pump be less than that otherwise 
required by this section.
    (c) Each pump must be capable of delivering water simultaneously 
from the outlets having the greatest pressure drop from the fire pumps 
to the nozzles which may not always be the two highest outlets, at a 
Pitot tube pressure of not less than 50 p.s.i. Where 1\1/2\-inch hose is 
permitted in lieu of 2\1/2\-inch

[[Page 343]]

hose by footnote 2 of Table 193.10-5(a), the pump capacity must be 
determined on the same basis as if 2\1/2\-inch hose had been permitted. 
Where \3/4\-inch hose is permitted by Table 193.10-5(a), the Pitot tube 
pressure may not be less than 35 p.s.i.
    (d) Fire pumps must be fitted on the discharge side with relief 
valves set to relieve at 25 p.s.i. in excess of the pressure necessary 
to maintain the requirements of paragraph (c) of this section or 125 
p.s.i., whichever is greater. Relief valves may be omitted if the pumps, 
operating under shutoff conditions, are not capable of developing a 
pressure exceeding this amount.
    (e) Fire pumps must be fitted with a pressure gage on the discharge 
side of the pumps.
    (f) Fire pumps may be used for other purposes provided at least one 
of the required pumps is kept available for use on the fire system at 
all times. In no case may a pump having connection to an oil line be 
used as a fire pump. Branch lines connected to the fire main for 
purposes other than fire and deck wash must be so arranged that adequate 
water can be made continuously available for firefighting purposes.
    (g) The total area of the pipes leading from a pump must not be less 
than the discharge area of the pump.
    (h) Where two fire pumps are required on vessels with main or 
auxiliary oil-fired boilers or with internal combustion propulsion 
machinery, the pumps must be located in separate spaces. The pumps, sea 
connections, and sources of power must be arranged to ensure that a fire 
in any one space will not put all of the fire pumps out of operation. 
However, where it is shown to the satisfaction of the Commandant that it 
is unreasonable or impracticable to meet this requirement, the 
installation of a fixed fire extinguishing system may be accepted as an 
alternate method of extinguishing any fire that would affect the 
powering and operation for the required fire pumps.
    (i) Except as provided for in Sec.  193.10-10(e), a sufficient 
number of hose streams for fire fighting purposes must be immediately 
available from the fire main at all times by either of the following 
methods:
    (1) Maintenance of water pressure. (i) Water pressure must be 
maintained on the fire main at all times by the continuous operation of:
    (A) One of the fire pumps; or
    (B) Another suitable pump capable of supplying one hose stream at a 
Pitot tube pressure of not less than 50 p.s.i. (35 p.s.i. for \3/4\-inch 
hose); or,
    (C) A pressure tank capable of supplying one hose stream at a Pitot 
tube pressure of not less than 50 p.s.i. (35 p.s.i. for \3/4\-inch hose) 
for five minutes.
    (ii) An audible alarm must be installed to sound in a continuously 
manned space if the pressure in the fire main drops to less than that 
necessary to maintain the minimum Pitot tube pressures specified in 
Sec.  193.10-5(i)(1)(i)(B).
    (2) Remote control of fire pumps. (i) At least one fire pump must be 
capable of remote activation and control.
    (ii) If the fire pump is in a continuously manned machinery space, 
the controls for operating it and the controls for all necessary valves 
must be located on the manned operating platform in that space.
    (iii) If the fire pump is in an unmanned machinery space, the 
controls for its operation and the controls for all necessary valves 
must be located in:
    (A) The fire control station, if any; or,
    (B) The bridge, if there is no fire control station; or,
    (C) A readily accessible space acceptable to the Officer in Charge, 
Marine Inspection.

Sec.  193.10-10  Fire hydrants and hose.

    (a) The size of fire hydrants, hose, and nozzles and the length of 
hose required must be as noted in Table 193.10-5(a) of this subpart.
    (b) In 2\1/2\-inch hose and hydrants specified in Table 193.10-5(a) 
of this subpart, on vessels of more than 1,500 gross tons, the hydrants 
in interior locations may have wye connections for 1\1/2\-inch hose. In 
these cases, the hose must be 75 feet (22.86 meters) in length, and only 
one hose will be required at

[[Page 344]]

each fire station; however, if all such stations can be satisfactorily 
served with 50-foot lengths, 50-foot hose may be used. The hydrants for 
exterior locations may substitute two 1\1/2\-inch outlets, each with a 
1\1/2\-inch hose, supplied through a wye connection.
    (c) On vessels of 500 gross tons or more there must be at least one 
shore connection to the fire main available to each side of the vessel 
in an accessible location. Suitable cutout valves and check valves must 
be provided for furnishing the vessel's shore connections with couplings 
mating those on the shore fire lines. Vessels of 500 gross tons or more 
on an international voyage, must be provided with at least one 
international shore connection complying with ASTM F 1121 (incorporated 
by reference, see Sec.  193.01-3). Facilities must be available enabling 
an international shore connection to be used on either side of the 
vessel.
    (d) Fire hydrants must be of sufficient number and so located that 
any part of the vessel, other than main machinery spaces, may be reached 
with at least 2 streams of water from separate outlets, at least one of 
which must be from a single length of hose. In main machinery spaces, 
all portions of such spaces must be capable of being reached by at least 
2 streams of water, each of which must be from a single length of hose 
from separate outlets; however, this requirement need not apply to shaft 
alleys containing no assigned space for the stowage of combustibles. 
Fire hydrants must be numbered as required by Sec.  196.37-15 of this 
subchapter.
    (e) All parts of the fire main located on exposed decks must either 
be protected against freezing or be fitted with cutout valves and drain 
valves so that the entire exposed parts of such piping may be shut off 
and drained in freezing weather. Except when closed to prevent freezing, 
such valves must be sealed open.
    (f) The outlet at the fire hydrant must be limited to any position 
from the horizontal to the vertical pointing downward, so that the hose 
will lead horizontally or downward to minimize the possibility of 
kinking.
    (g) Each fire hydrant must be provided with a single length of hose 
with nozzle attached and a spanner wrench. A suitable hose rack or other 
device must be provided for the proper stowage of the hose. If the hose 
is not stowed in the open or behind glass so as to be readily seen, the 
enclosures must be marked in accordance with Sec.  196.37-15 of this 
subchapter.
    (h) Firehoses must be connected to the outlets at all times. 
However, at open decks where no protection is afforded to the hose in 
heavy weather, the hose may be temporarily removed from the hydrant and 
stowed in an accessible nearby location.
    (i) Each fire hydrant must have at least 1 length of firehose. Each 
firehose must have a combination solid stream and water spray nozzle 
that is approved under subpart 162.027 of this subchapter, except 19 
millimeters (3/4 inch) hose may have a garden hose nozzle that is bronze

  Subpart 193.15_Carbon Dioxide and Clean Agent Extinguishing Systems, 
                                 Details



Sec.  193.15-1  Application.

    (a) The provisions of this subpart shall apply to all new 
installations contracted for on or after March 1, 1968.
    (b) Installations contracted for prior to March 1, 1968, shall meet 
the requirements of Sec.  193.15-90.
    (c) The requirements of this subpart are based on a ``high pressure 
system,''

[[Page 346]]

i.e., one in which the carbon dioxide is stored in liquid form at 
atmospheric temperature. Details for ``low pressure systems,'' i.e., 
those in which the carbon dioxide is stored in liquid form at a 
continuously controlled low temperature, may be specifically approved by 
the Commandant where it is demonstrated that a comparable degree of 
safety and fire extinguishing ability is achieved.



Sec.  193.15-5  Quantity, pipe sizes, and discharge rates.

    (a) General. The amount of carbon dioxide required for each space 
shall be as determined by paragraphs (b) through (d) of this section.
    (b) Total available supply. A separate supply of carbon dioxide need 
not be provided for each space protected. The total available supply 
shall be at least sufficient for the space requiring the greatest 
amount.
    (c) Enclosed ventilation systems for rotating electrical propulsion 
equipment. (1) The number of pounds of carbon dioxide required for the 
initial charge shall be equal to the gross volume of the system divided 
by 10 for systems having a volume of less than 2,000 cubic feet, and 
divided by 12 for systems having a volume of 2,000 cubic feet or more.
    (2) In addition to the amount required by paragraph (c)(1) of this 
section there shall be sufficient carbon dioxide available to permit 
delayed discharges of such quantity as to maintain at least a 25-percent 
concentration until the equipment can be stopped. If the initial 
discharge is such as to achieve this concentration until the equipment 
is stopped, no delayed discharge need be provided.
    (3) The piping for the delayed discharge shall not be less than \1/
2\-inch standard pipe, and no specific discharge rate need be applied to 
such systems. On small systems, this pipe may be incorporated with the 
initial discharge piping.
    (4) The piping for the initial charge shall be in accordance with 
Table 193.15-5(d)(4), and the discharge of the required amount shall be 
completed within 2 minutes.
    (d) Machinery spaces, paint lockers, tanks, chemical storerooms, and 
similar spaces. (1) Except as provided in paragraph (d)(3) of this 
section, the number of pounds of carbon dioxide required for each space 
shall be equal to the gross volume of the space divided by the 
appropriate factor noted in Table 193.15-5(d)(1). If fuel can drain from 
the compartment being protected to an adjacent compartment, or if the 
compartments are not entirely separate, the requirements for both 
compartments shall be used to determine the amount of carbon dioxide to 
be provided. The carbon dioxide shall be arranged to discharge into both 
such compartments simultaneously.

                          Table 193.15-5(d)(1)

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

    (2) For the purpose of the requirements of this paragraph, the 
volume of the machinery space shall be taken as exclusive of the normal 
machinery casing unless the boiler, internal combustion machinery, or 
fuel oil installations extend into such space, in which case the volume 
shall be taken to the top of the casing or the next material reduction 
in casing area, whichever is lower. ``Normal machinery casing'' and 
``material reduction in casing area'' shall be defined as follows:
    (i) By ``normal machinery casing'' shall be meant a casing the area 
of which is not more than 40 percent of the maximum area of the 
machinery space.
    (ii) By ``material reduction in casing area'' shall be meant a 
reduction to at least 40 percent of the casing area.
    (3) For vessels on an international voyage contracted for on or 
after May 26, 1965, the amount of carbon dioxide required for a space 
containing propulsion boilers or internal combustion propulsion 
machinery shall be as given by paragraphs (d)(1) and (2) of this section 
or by dividing the entire volume, including the casing, by a factor of 
25, whichever is the larger.
    (4) Branch lines to the various spaces shall be as noted in Table 
193.15-5(d)(4).

    (5) Distribution piping within the space shall be proportioned from 
the supply line to give proper distribution to the outlets without 
throttling.
    (6) The number, type, and location of discharge outlets shall be 
such as to give a uniform distribution throughout the space.
    (7) The total area of all discharge outlets shall not exceed 85 
percent nor be less than 35 percent of the normal cylinder outlet area 
or the area of the supply pipe, whichever is smaller. The nominal 
cylinder outlet area in square inches shall be determined by multiplying 
the factor 0.0022 by the number of pounds of carbon dioxide required, 
except that in no case shall this outlet area be less than 0.110 square 
inch.
    (8) The discharge of at least 85 percent of the required amount of 
carbon dioxide shall be complete within 2 minutes.



Sec.  193.15-10  Controls.

    (a) Except as noted in Sec.  193.15-20(b), all controls and valves 
for the operation of the system shall be outside the space protected and 
shall not be located in any space that might be cut off or made 
inaccessible in the event of fire in any of the spaces protected.
    (b) If the same cylinders are used to protect more than one hazard, 
a manifold with normally closed stop valves shall be used to direct the 
carbon dioxide into the proper space. If cylinders are used to protect 
only one hazard, a normally closed stop valve shall be installed between 
the cylinders and the hazard except for systems of the type indicated in 
Sec.  193.15-5(d) which contain not more than 300 pounds of carbon 
dioxide.
    (c) One of the stations controlling the system for the main 
machinery space and the chemical storerooms shall be located as 
convenient as practicable to one of the main escapes from these spaces. 
All control stations and the individual valves and controls shall be 
marked as required by Sec. Sec.  196.37-10 and 196.37-13 of this 
subchapter.
    (d) Systems of the type indicated in Sec.  193.15-5(d) shall be 
actuated by one control operating the valve to the space and a separate 
control releasing at least the required amount of carbon dioxide. These 
two controls shall be located in a box or other enclosure clearly 
identified for the particular space. Those systems installed without a 
stop valve shall be operated by one control releasing at least the 
required amount of carbon dioxide.
    (e) Where provisions are made for the simultaneous release of a 
given amount of carbon dioxide by operation of a remote control, 
provisions shall also be made for manual control at the cylinders. Where 
gas pressure from pilot cylinders is used as a means for releasing the 
remaining cylinders, not less than two pilot cylinders shall be used for 
systems consisting of more than two cylinders. Each of the pilot 
cylinders shall be capable of manual control at the cylinder, but the 
remaining cylinders need not be capable of individual manual control.
    (f) Systems of the type indicated in Sec.  193.15-5(d), other than 
systems for tanks, which are of more than 300 pounds of carbon dioxide, 
shall be fitted with an approved delayed discharge so arranged that the 
alarm will be sounded for at least 20 seconds before the carbon dioxide 
is released into the space. Such systems of not more than 300 pounds of 
carbon dioxide shall also have a similar delayed discharge, except for 
those systems for tanks and for spaces which have a suitable horizontal 
escape.
    (g) All distribution valves and controls shall be of an approved 
type. All controls shall be suitably protected.
    (h) Complete but simple instructions for the operation of the 
systems must be located in a conspicuous place at or near all pull 
boxes, stop valve controls and in the CO2 cylinder storage 
room. On systems in which the CO2 cylinders

[[Page 348]]

are not within the protected space, these instructions must also include 
a schematic diagram of the system and instructions detailing alternate 
methods of discharging the system should the manual release or stop 
valve controls fail to operate. Each control valve to branch lines must 
be marked to indicate the related space served.
    (i) If the space or enclosure containing the carbon dioxide supply 
for controls is to be locked, a key to the space or enclosure shall be 
in a break-glass-type box conspicuously located adjacent to the opening.

6209, Feb. 10, 1975]



Sec.  193.15-15  Piping.

    (a) The piping, valves, and fittings shall have a bursting pressure 
of not less than 6,000 pounds per square inch.
    (b) All piping, in nominal sizes not over \3/4\ inch shall be at 
least Schedule 40 (standard weight) and in nominal sizes over \3/4\ 
inch, shall be at least Schedule 80 (extra heavy).
    (c) All piping valves, and fittings of ferrous materials shall be 
protected inside and outside against corrosion unless specifically 
approved otherwise by the Commandant.
    (d) A pressure relief valve or equivalent set to relieve between 
2,400 and 2,800 pounds per square inch shall be installed in the 
distribution manifold or such other location as to protect the piping in 
the event that all branch line shutoff valves are closed.
    (e) All dead-end lines shall extend at least 2 inches beyond the 
last orifice and shall be closed with cap or plug.
    (f) All piping, valves, and fittings shall be securely supported, 
and where necessary, protected against injury.
    (g) Drains and dirt traps shall be fitted where necessary to prevent 
the accumulation of dirt or moisture. Drains and dirt traps shall be 
located in accessible locations where possible.
    (h) Piping shall be used for no other purpose except that it may be 
incorporated with the fire-detecting system.
    (i) Piping passing through living quarters shall not be fitted with 
drains or other openings within such spaces.
    (j) Installation test requirements are:
    (1) Upon completion of the piping installation, and before the 
cylinders are connected, a pressure test shall be applied as set forth 
in this paragraph. Only carbon dioxide or other inert gas shall be used 
for this test.
    (2) The piping from the cylinders to the stop valves in the manifold 
shall be subjected to a pressure of 1,000 pounds per square inch. With 
no additional gas being introduced to the system, it shall be 
demonstrated that the leakage of the system is such as not to permit a 
pressure drop of more than 150 pounds per square inch per minute for a 
2-minute period.
    (3) The individual branch lines to the various spaces protected 
shall be subjected to a test similar to that described in the preceding 
subparagraph with the exception that the pressure used shall be 600 
pounds per square inch in lieu of 1,000 pounds per square inch. For the 
purpose of this test, the distribution piping shall be capped within the 
space protected at the first joint ahead of the nozzles.
    (4) In lieu of the tests prescribed in the preceding paragraphs in 
this paragraph, small independent systems protecting spaces such as 
emergency generator rooms, lamp lockers, chemical storerooms, etc., may 
be tested by blowing out the piping with air at a pressure of at least 
100 pounds per square inch.



Sec.  193.15-16  Lockout valves.

    (a) A lockout valve must be provided on any carbon dioxide 
extinguishing system protecting a space over 6,000 cubic feet in volume 
and installed or altered after [July 9, 2013. ``Altered'' means modified 
or refurbished beyond the maintenance required by the manufacturer's 
design, installation, operation and maintenance manual.
    (b) The lockout valve must be a manually operated valve located in 
the discharge manifold prior to the stop valve or selector valves. When 
in the closed position, the lockout valve must provide complete 
isolation of the system from the protected space or spaces, making it 
impossible for carbon dioxide to discharge in the event of equipment 
failure during maintenance.

[[Page 349]]

    (c) The lockout valve design or locking mechanism must make it 
obvious whether the valve is open or closed.
    (d) A valve is considered a lockout valve if it has a hasp or other 
means of attachment to which, or through which, a lock can be affixed, 
or it has a locking mechanism built into it.
    (e) The master or person-in-charge must ensure that the valve is 
locked open at all times, except while maintenance is being performed on 
the extinguishing system, when the valve must be locked in the closed 
position.
    (f) Lockout valves added to existing systems must be approved by the 
Commandant as part of the installed system.

Sec.  197.505  Definitions.

    As used in this subpart--
    Action level means an airborne concentration of benzene of 0.5 parts 
of benzene per million parts of air calculated as an eight hour time-
weighted average, generated from vessels regulated by this subpart.
    Authorized person means a person specifically authorized by the 
person in charge of the vessel to enter a regulated area.
    Benzene means liquefied or gaseous benzene (C6 
H6; Chemical Abstracts Service Registry No. 71-43-2) and 
includes benzene contained in liquid mixtures and the benzene vapors 
released by these mixtures. The term does not include trace amounts of 
unreacted benzene contained in solid materials.
    Breathing zone means the area within one foot of a person's mouth 
and nose.
    Employee means an individual who is on board a vessel by reason of 
that individual's employment and who is employed directly by the owner, 
charterer, managing operator, or agent of that vessel.
    Employer means the owner, charterer, managing operator, or agent of 
a vessel.
    Emergency means an occurrence, such as an equipment failure, a 
container rupture, or a control equipment failure, which results or may 
result in an unexpected release of benzene.
    Operations involving benzene means any operation that could subject 
a worker to benzene exposures above the PEL, including cargo transfer 
operations involving connecting or disconnecting liquid or vapor hoses; 
cargo tank gauging and sampling; and cargo tank gas freeing, venting, 
and cleaning.
    Performance standard means the standard in Sec.  197.520.
    Person in charge means--
    (1) For a self propelled vessel, the master or licensed operator of 
the vessel; and
    (2) For an unmanned barge,
    (i) The licensed operator of the vessel for barge tows;
    (ii) Where there is no licensed operator, the tankerman who signs 
the declaration of inspection for a cargo transfer for an operation 
involving benzene; or
    (iii) Where there is no licensed operator or tankerman, the 
individual in charge of the vessel when it is moored at a fleet, 
terminal, or other place.
    Permissible exposure limits or PELs mean the exposure limits 
specified in Sec.  197.515.
    Personal exposure means the concentration of airborne benzene to 
which a person would be exposed if that person were not using a properly 
fitted respirator in compliance with Sec.  197.550 and the personal 
protective clothing and equipment in compliance with Sec.  197.555.
    Regulated area means an area designated in compliance with Sec.  
197.535.

concentration of one part of benzene per million parts of air (one ppm), 
as averaged over an eight-hour period. This eight hour period covers the 
time, up to eight hours, that the employee works in any 24 hour period. 
If the exposure period is less than eight hours within the 24 hour 
period, the difference between eight hours and the time of exposure 
(that is, the unexposed time) is averaged into the TWA. If the exposure 
period exceeds eight hours in any 24 hour period, sum the products of 
each exposure level multiplied by the time at that exposure level. The 
TWA is the value of that sum divided by eight hours.
    Vapor control or recovery system means a system of piping and 
equipment used to collect vapors by transporting the vapors from a tank 
being loaded to a tank being unloaded or by collecting the vapors and 
containing them, recovering them, dispersing them in a location remote 
from personnel, or destroying them.

this section, reference 46 CFR 197.530, state the date of the 
certification, and be signed by the person making the certification. A 
sample certification form is contained in appendix F of this subpart.

[[Page 402]]

    (c) Before the nonemployee making the certification engages in a 
benzene operation on a vessel, that person or a representative of the 
entity which employs that person must show a copy of the certification 
to the person in charge of the vessel and the person in charge must 
examine the certification to ensure compliance with the requirements of 
this section.



Sec.  197.535  Regulated areas.

    (a) Based on the employer's evaluation of the environmental 
monitoring, whenever the airborne concentration of benzene within an 
area exceeds or reasonably can be expected to exceed the permissible 
exposure limits, the person in charge shall mark the area as a regulated 
area.
    (b) The person in charge shall restrict access to regulated areas to 
authorized persons wearing an appropriate respirator in compliance with 
Sec.  197.550 and the personal protective clothing and equipment in 
compliance with Sec.  197.555. The person in charge shall not allow any 
person to enter a regulated area without another individual in the 
vicinity to perform rescue or call for help. The second individual must 
maintain communication with the one entering the regulated area or keep 
that individual in sight. Also, the second individual must be located at 
the point of access during confined space entry.
    (c) The boundaries of regulated areas must be indicated by 
barricades, other devices, or by painted areas on the vessel. A sign 
bearing the following legend in letters at least three inches high 
(except for the words ``DANGER--BENZENE'', which must be printed in 
letters at least 50 percent larger than the other words) must be posted 
at each access to the regulated areas:

                             DANGER--BENZENE

                             REGULATED AREA

                          CANCER CAUSING AGENT

                          FLAMMABLE--NO SMOKING

                        AUTHORIZED PERSONNEL ONLY

                           RESPIRATOR REQUIRED



Sec.  197.540  Determination of personal exposure.

    (a) General. (1) The employer shall ensure that one or more persons 
in each type of operation conducted on the vessel which involves the 
handling of or potential exposure to benzene are monitored. The 
monitoring must be conducted so as to determine the representative 
personal exposure of all persons engaged in each particular operation 
involving benzene. Monitoring one vessel of a class is sufficient for 
all vessels of that class provided the procedures, equipment, work 
practices, cargo, and control equipment are substantially the same.
    (2) For long duration operations, such as cargo loading or tank 
entry, the persons monitored must be monitored to determine the 
representative TWA for all persons engaged in the operation. The 
monitoring must be based on breathing zone air samples taken for the 
duration of the operation or for eight hours, whichever is less.
    (3) For short duration operations, such as tank gauging or hose 
connection and disconnection, the persons monitored must be monitored to 
determine the representative short term exposure level for all persons 
engaged in the operation. The monitoring must be based on 15 minute 
breathing zone air samples. Brief period measuring devices may be used 
to determine whether monitoring for the short term exposure level is 
needed.
    (4) If cargoes with different benzene concentrations are being 
carried on the vessel, an operation involving the lower concentration 
cargoes need not be monitored if the same type of operation involving 
the highest concentration cargo is monitored and found to be below the 
action level.
    (5) Initial monitoring must be conducted during weather conditions 
typical in the geographic area and during

[[Page 403]]

the time of day the operation is normally conducted. If the benzene 
level is above half the action level for the operation, additional 
monitoring must be conducted under those weather conditions that will 
maximize benzene exposure, such as low wind, stable air, and high 
temperature.
    (6) The monitoring method used must be accurate to a confidence 
level of 95 percent to within plus or minus 25 percent for airborne 
concentrations of benzene equal to or greater than 0.5 ppm.
    (b) Initial exposure monitoring. When benzene is first loaded as a 
cargo on board a vessel, an initial monitoring of each type of operation 
must be conducted to determine accurately the representative personal 
exposure of persons involved in the operation.
    (c) Periodic exposure monitoring. The monitoring must be repeated 
each July or August if benzene containing cargoes are carried during 
those months; monitoring must be conducted under those weather 
conditions that will maximize benzene exposure, such as low wind, stable 
air, and high temperature. If benzene containing cargoes are not carried 
during those months, monitoring must be conducted at the time of 
carriage nearest those months; monitoring must be conducted under those 
weather conditions that will maximize benzene exposure, such as low 
wind, stable air, and high temperature.
    (d) Additional exposure monitoring. (1) Monitoring in compliance 
with paragraphs (b) and (c) of this section must be repeated for the 
operation when there has been a change in the procedure, equipment, or 
work practices of the operation which may increase personal exposure or 
whenever the employer or person in charge has any reason to suspect that 
personal exposure has increased.
    (2) Whenever emergencies occur that may increase personal exposure, 
operations affected by the emergency must be monitored using area or 
personal sampling after the spill is cleaned up or the leak, rupture, or 
other breakdown is repaired to determine when personal exposure has 
returned to the level that existed before the emergency. There must be 
monitoring equipment aboard each ship.
    (3) For those cases in which the benzene exposure can vary 
significantly over the year, the personnel exposure reduction plan can 
reflect this variation in time if both initial and periodic exposure 
monitoring are conducted at those times. There must be sufficient 
monitoring to quantitatively justify differences in the exposure 
reduction program over the course of the year. The exposure monitoring 
must be conducted under those weather conditions that will maximize 
benzene exposure, such as low wind, stable air, and high temperature.
    (4) The Coast Guard may require additional monitoring upon 
reasonable belief that the PEL's are being exceeded.
    (e) Notification of exposure monitoring results. (1) Within 60 
working days after the receipt of the results of monitoring in 
compliance with this section, each person involved in the operation 
monitored must be given written notice of the results, either by 
separate letter or by notice posted in a location accessible to all 
persons involved.
    (2) If the results indicate that the PELs were exceeded, the written 
notice required by paragraph (e)(1) of this section must state, or refer 
to a document available to the persons involved which states, the 
corrective action to be taken to reduce the personal exposure to or 
below the PELs.

[CGD 88-040, 56 FR 52135, Oct. 17, 1991; 56 FR 65006, Dec. 13, 1991; CGD 
95-028, 62 FR 51221, Sept. 30, 1997]



Sec.  197.545  Program to reduce personal exposure.

    (a) When personal exposure for an operation is over the applicable 
PEL as determined in compliance with Sec.  197.540, the employer shall 
develop and implement, within 60 working days of the date of that 
determination, a written program detailing the corrective actions that 
will be taken to reduce personal exposure to or below the PEL's. The 
written program must include a timeframe for implementing the corrective 
actions to be taken.
    (b) Corrective actions in compliance with paragraph (a) of this 
section may include, but are not limited to, one or more of the 
following:

[[Page 404]]

    (1) Engineering controls (e.g. vapor control or recovery systems, 
closed loading systems, or controlled venting systems);
    (2) Revised work practices; or
    (3) Respirators in compliance with Sec.  197.550 and personal 
protective clothing and equipment in compliance with Sec.  197.555.
    (c) Whenever the exposure monitoring data show a significant 
increase in personnel exposure, the program must be revised to reflect 
the new data.
    (d) Each person involved in the operation must be notified that a 
written program detailing corrective actions is available upon request.
    (e) A copy of the written program must be furnished upon request to 
the Coast Guard.



Sec.  197.550  Respiratory protection.

    (a) General. When the use of respirators in compliance with this 
section and the personal protective clothing and equipment in compliance 
with Sec.  197.555 is chosen as the method or one of the methods in 
compliance with Sec.  197.545 to be used in meeting the performance 
standard, the respirators used must be selected and fitted according to 
this section.
    (b) Respirator selection. (1) The respirator must be approved by the 
Mine Safety and Health Administration (MSHA) in compliance with 30 CFR 
part 11. When filter elements are used, they must include MSHA approval 
for organic vapors or benzene.
    (2) The employer shall provide affected employees with the 
appropriate respirators without charge and ensure that the respirators 
are used properly. Any employee determined by the testing physician as 
being unable to wear negative pressure respirators, who continues to be 
subject to exposure over the PEL, must be given the option of wearing a 
respirator with less breathing resistance, such as a powered air-
purifying respirator or a supplied air respirator.
    (3) Electrically powered respiratory protective equipment must meet 
the electrical engineering requirements in subchapter J of this chapter 
and the electrical equipment requirements in part 151, table 151.05, and 
part 153, table 1, of this chapter.
    (4) The type of respirator provided must be a type specified in 
table 197.550(b) of this section that is appropriate for the exposure.

------------------------------------------------------------------------
\1\ Canisters for non-powered air purifying respirators must have a
  minimum service life of four hours when tested at 150 ppm benzene, at
  a flow rate of 64 liters/minute at 25 [deg]C and 85% relative
  humidity. Canisters for powered air-purifying respirators must have a
  flow rate of 115 liters/minute (for tight fitting respirators) or 170
  liters/minute (for loose fitting respirators).

    (c) Respirator fit testing. (1) Before the person is permitted to 
use a respirator selected and fitted in compliance with this section, 
the person must undergo an Initial Fit Test (IFT) and either a 
Qualitative Fit Test (QLFT) or a Quantitative Fit Test (QNFT), in 
compliance with Appendix E of this subpart, using the respirator fitted. 
If a negative pressure respirator is used, the QLFT or QNFT must be 
repeated at least once a year thereafter.
    (2) The objective of the tests is to identify for the person a 
respirator which minimizes the chance of leakage.
    (3) The person conducting the tests required by paragraph (c)(1) of 
this section must understand the purpose of these tests and how to 
perform them.

[[Page 405]]

    (4) The person conducting the tests required by paragraph (c)(1) of 
this section must certify the results by signing the test report.
    (d) Respirator fitting. (1) Employees who are being fitted for 
respirators must be trained in the methods for properly fitting a 
respirator and informed of the factors which may affect a proper fit, 
such as beards, sideburns, dentures, eyeglasses, and goggles, and that 
an unobstructed sealing surface is critical in fitting a respirator. 
(See appendix E of this subpart).
    (2) For employees requiring eye glasses, corrective lenses should be 
fitted to the respirator faceplate. As a temporary measure, glasses with 
short temple bars may be taped to the wearer's head. Contact lenses 
other than soft lenses or gas permeable lenses must not be worn with 
respirators.
    (e) Respirator use. Persons wearing a respirator in a regulated area 
must be permitted to leave the regulated area to wash their face and 
respirator facepiece, as necessary, in order to prevent skin irritation 
associated with respirator use or, if an air-purifying respirator is 
used, to change the filter elements whenever the person wearing the 
respirator detects a change in breathing resistance or a chemical vapor 
breakthrough.
    (f) Respirator inspection. Respirators must be inspected in 
accordance with ANSI Z88.2--1980, section 8.
    (g) Respirator maintenance. (1) Respirators must be maintained in 
accordance with ANSI Z88.2--1980, section 8.
    (2) During respirator cleaning, the rubber or elastomer parts of the 
respirator must be stretched and manipulated with a massaging action to 
keep the parts pliable and flexible and to keep the parts from taking a 
set during storage.
    (3) The air purifying element of air-purifying respirators must be 
replaced when the employee detects breakthrough or after a period not to 
exceed eight hours, whichever comes first. The element must also be 
replaced at the start of each shift. An air purifying element with an 
end of useful life indicator approved by MSHA or NIOSH for benzene may 
be used until the indicator indicates end of useful life even if this 
exceeds eight hours.
    (h) Respirator storage. Respirators must be stored in accordance 
with ANSI Z88.2--1980, section 8.

Sec.  197.555  Personal protective clothing and equipment.

    (a) When the use of respirators in compliance with Sec.  197.550 and 
the personal protective clothing and equipment in compliance with this 
section is chosen as the method or one of the methods required by Sec.  
197.545 to be used in meeting the performance standard, the clothing and 
equipment must meet the requirements of this section.
    (b) The employer shall provide employees with the necessary personal 
protective clothing and equipment without charge and shall ensure that 
the clothing and equipment are worn or used properly.
    (c) Employees must be provided with coveralls or a large apron, 
boots, gloves, and, if necessary, tight-fitting eye goggles to limit 
dermal exposure to, and prevent eye contact with, liquid benzene.



Sec.  197.560  Medical surveillance.

    (a) General. (1) The employer must provide, and the employees must 
submit to, the medical surveillance examinations for employees, as 
required by this section.
    (2) All medical surveillance procedures in compliance with this 
section, other than the pulmonary function test of paragraph (b)(5)(v) 
of this section and all laboratory tests, must be performed by, or under 
the supervision of, a licensed physician.
    (3) The pulmonary function test of paragraph (b)(5)(v) of this 
section must be administered by a licensed physician or by a person who 
has completed a training course in spirometry sponsored by a 
governmental, academic, or professional institution.
    (4) All laboratory tests must be conducted by a laboratory 
accredited by an accrediting organization acceptable to the Commandant.
    (b) Initial medical examination. (1) Within March 14, 1992 the 
employer shall make available to the employees

[[Page 406]]

listed in paragraph (b)(2)(i) of this section an initial medical 
examination. Within six months all initial medical examinations must be 
completed, including those for the employees listed in paragraph 
(b)(2)(ii), and each employee notified of the results of that employee's 
examination.
    (2) The initial medical examination must be made available to the 
following employees before they are permitted to enter or continue 
working in a workplace in which they will be or may be exposed to 
benzene:
    (i) Employees who were exposed to more than 10 ppm of benzene as an 
eight-hour TWA on at least 30 calendar days during the year before 
January 15, 1992 and who were employed by their present employer during 
each of the 30 days.
    (ii) Employees, other than employees defined in paragraph (b)(2)(i) 
of this section, who may reasonably be expected to be exposed to benzene 
at or above the action level on at least 30 calendar days, or at a level 
above a PEL on at least 10 calendar days, during the coming year.
    (3) Exposure to benzene, as referred to in paragraph (b)(2) of this 
section, means any exposure to benzene, whether or not at the time of 
the exposure, the employee was or will be wearing an appropriate 
respirator in compliance with Sec.  197.550 and the personal protective 
clothing and equipment in compliance with Sec.  197.555.
    (4) An initial medical examination is not required if the employer 
or employee has adequate records showing that the employee has had, 
within one year, an examination meeting the requirements of paragraph 
(b)(5) of this section.
    (5) The initial medical examination must include at least the 
following elements:
    (i) A detailed occupational history which includes a history of past 
work exposure to benzene or any other hematological toxin, a family 
history of blood dyscrasias including hematological neoplasms, a history 
of blood dyscrasias including genetic hemoglobin abnormalities, bleeding 
abnormalities, and abnormal functions of formed blood elements, a 
history of renal or liver dysfunction, a history of medicinal drugs 
routinely taken, a history of previous exposure to ionizing radiation, 
and a history of exposure to marrow toxins outside of the employee's 
current work situation. The employee must provide to the examining 
physician as complete an occupational history as possible for the period 
prior to the current employment.
    (ii) A complete physical examination.
    (iii) A complete blood count, including a leukocyte count, with 
differential, quantitative thrombocyte count, hematocrit, hemoglobin, 
erythrocyte count. and erythrocyte indices (MCV, MCH, MCHC). The results 
of these tests must be reviewed by the examining physician.
    (iv) As determined necessary by the examining physician, additional 
tests based on alterations to the components of the blood or other signs 
which may be related to benzene exposure.
    (v) For employees required to wear respirators for at least 30 days 
a year, a pulmonary function test.
    (c) Periodic medical examinations. (1) The employer shall ensure 
that no one performs a benzene operation exceeding the level criteria of 
paragraph (b)(2) of this section without having undergone an initial 
medical examination and periodic medical examinations yearly thereafter. 
Also, those who in the previous year have performed benzene operations 
exceeding the level criteria of paragraph (b)(2) of this section shall 
undergo a periodic medical examination even if they will not perform 
benzene operations in the current year. Periodic examinations must 
include, at least, the following elements:
    (i) A brief history regarding new exposure to potential marrow 
toxins, changes in medicinal drug use, and the appearance of physical 
signs relating to blood disorders.
    (ii) A complete blood count, including a leukocyte count with 
differential, quantitative thrombocyte count, hematocrit, hemoglobin, 
erythrocyte count, and erythrocyte indices (MCV, MCH, MCHC). The results 
of these tests must be reviewed by the examining physician.
    (iii) As determined necessary by the examining physician, additional 
tests based on alterations to the components

[[Page 407]]

of the blood or other signs which may be related to benzene exposure.
    (2) If the employee develops signs and symptoms commonly associated 
with toxic exposure to benzene, the employee must be provided with an 
additional medical examination which includes those elements considered 
appropriate by the examining physician.
    (3) For employees required to use respirators for at least 30 days a 
year, a pulmonary function test must be performed, and specific 
evaluation of the cardiopulmonary system must be made, at least every 
three years.
    (d) Additional examinations and referrals. (1) If the results of the 
complete blood count laboratory test required for the initial or 
periodic medical examination indicate that any of the following abnormal 
conditions exist, the blood count must be retaken within four weeks:
    (i) The hemoglobin or the hematocrit falls below the normal limit 
(outside the 95% confidence interval (C.I.)), as determined by the 
laboratory, or the hemoglobin or hematocrit shows a persistent downward 
trend from the employee's pre-exposure norms, if these findings cannot 
be explained by other medical reasons.
    (ii) The thrombocyte count varies more than 20 percent below the 
employee's most recent values or falls outside the normal limit (95% 
C.I.), as determined by the laboratory.
    (iii) The leukocyte count is below 4,000 per cubic millimeter or 
there is an abnormal differential count.
    (2) If the abnormal conditions persist, the employee must be 
referred by the examining physician to a hematologist or an internist 
for further evaluation, unless the physician has good reason to believe 
that the referral is unnecessary. (See appendix C of this subpart for 
examples of conditions in which referrals may be unnecessary.)
    (3) The hematologist or internist must be provided with the 
information provided to the physician in compliance with paragraph (f) 
of this section and with the medical record in compliance with Sec.  
197.570(b).
    (4) If the hematologist or internist determines that additional 
tests are needed, the employer shall ensure that these additional tests 
are provided. These test must be completed in thirty days, whether or 
not the employee continues to perform benzene operations.
    (e) Emergency medical examinations. (1) Whenever an employee is 
exposed to benzene resulting from an emergency, a sample of that 
employee's urine must be taken at the end of the employee's shift and a 
urinary phenol test must be performed on the sample within 72 hours. 
Where due to unavoidable circumstances the sample cannot be tested by a 
laboratory within 72 hours of exposure, the sample shall be frozen until 
it can be delivered to the laboratory. The specific gravity of the urine 
must be corrected to 1.024. Since certain foods and medications can 
result in elevated phenol levels, the employee must provide the 
physician with a dietary and medication history.
    (2) If the result of the urinary phenol test is below 75 mg phenol/l 
of urine, no further testing is required.
    (3) If the result of the urinary phenol test is equal to or greater 
than 75 mg phenol/l of urine, the employee's complete blood count 
including an erythrocyte count, a leukocyte count with differential, and 
a thrombocyte count must be taken at monthly intervals for a duration of 
three months following the emergency.
    (4) If any of the conditions specified in paragraph (d)(1) of this 
section exists, the additional examinations and referrals specified in 
paragraph (d) of this section must be performed and the employee must be 
provided with periodic medical examinations, if any are recommended by 
the examining physician.
    (f) Information provided to the physician. The following information 
must be provided to the examining physician:
    (1) A copy of this subpart and its appendices.
    (2) A description of the affected employee's duties as they relate 
to the employee's exposure.
    (3) The employee's actual or representative exposure level.
    (4) A description of the respirator and personal protective clothing 
and equipment used or to be used, if any.
    (5) Records of all previous employment-related medical examinations 
of

[[Page 408]]

the affected employee which were conducted while in the employ of the 
current employer and which have not been provided to the examining 
physician.
    (g) Physician's written opinion. (1) The employer shall ensure that, 
within 45 days of each examination required by this section, the 
employer and the employee must be provided with a copy of the examining 
physician's written opinion of the examination.
    (2) The written opinion must contain at least the following 
information:
    (i) The occupationally pertinent results of the medical examination 
and tests.
    (ii) All medical conditions, if any, of the employee which the 
examining physician believes would subject the employee to a greater 
than normal risk of material impairment of health if the employee is 
exposed again to benzene.
    (iii) The examining physician's recommended limitations, if any, 
upon the employee's future exposure to benzene or use of respirators or 
other personal protective clothing or equipment.
    (iv) A statement that the employee has been informed by the 
physician of the results of the medical examination and of all medical 
conditions of the employee resulting from benzene exposure which require 
further explanation or treatment.
    (3) The physician's written opinion must not reveal specific 
records, findings, or diagnoses that have no bearing on the employee's 
ability to work in a benzene-exposed workplace, ability to use a 
respirator, or ability to use personal protective clothing or equipment.
    (h) Removal from exposure. (1) From the time an employee is referred 
to a hematologist or internist in compliance with paragraph (d)(2) of 
this section, the employee must not be permitted to enter areas where 
personal exposure may exceed the action level until the physician 
determines in compliance with paragraph (h)(2) of this section that the 
employee again may enter those areas.
    (2) After examination by and consultation with the hematologist or 
internist, the examining physician decides whether or not to permit the 
employee to enter areas where personal exposure may exceed the action 
level. The employee must provide the employer with a written copy of the 
physician's decision signed by the physician. If the decision recommends 
that the employee not be permitted to enter those areas, the decision 
must include the examining physician's opinion as to when the employee 
may be permitted to reenter those areas and the requirements for future 
medical examinations to review the decision.
    (3) Within six months of the date a decision in compliance with 
paragraph (h)(2) of this section not to permit reentry is made, the 
employee must be provided with a follow-up examination and a decision of 
the examining physician (based on the follow-up examination and 
consultation with a hematologist or internist) as to whether reentry 
should be permitted and, if so, when, or whether it should be 
permanently prohibited.

 Sec. Appendix A to Subpart C of Part 197--Sample Substance Safety Data 
                             Sheet, Benzene

                       I. Substance Identification

    (a) Substance: Benzene.
    (b) Performance standard exposure limits:
    (1) Airborne: The maximum time-weighted average (TWA) exposure limit 
is one part of benzene vapor per million parts of air (one ppm) for an 
eight-hour workday and the maximum short-term exposure limit (STEL) is 
five ppm for any 15-minute period.
    (2) Dermal: Eye contact must be prevented and skin contact with 
liquid benzene must be limited.
    (c) Appearance and odor: Benzene is a clear, colorless liquid with a 
pleasant, sweet odor. The odor of benzene does not provide adequate 
warning of its hazard.

                         II. Health Hazard Data

    (a) Ways in which benzene affects your health. Benzene can affect 
your health if you inhale it or if it comes in contact with your skin or 
eyes. Benzene is also harmful if you swallow it.
    (b) Effects of overexposure. (1) Short-term (acute) overexposure: If 
you are overexposed to high concentrations of benzene, well above the 
levels where its odor is first recognizable, you may feel breathless, 
irritable, euphoric, or giddy and you may experience irritation in your 
eyes, nose, and respiratory tract. You may develop a headache, feel 
dizzy, nauseated, or intoxicated. Severe exposures may lead to 
convulsions and loss of consciousness.
    (2) Long-term (chronic) exposure: Repeated or prolonged exposure to 
benzene, even at relatively low concentrations, may result in various 
blood disorders ranging from anemia to leukemia, an irreversible, fatal 
disease. Many blood disorders associated with benzene exposure may occur 
without symptoms.

                 III. Protective Clothing and Equipment

    (a) Respirators. Respirators are required for those operations in 
which engineering controls or work practice controls are not feasible 
for reducing exposure to the permissible level or are not chosen as the 
method of complying with the performance standard. If respirators are 
worn, they must have joint Mine Safety and Health Administration and the 
National Institute for Occupational Safety and Health (NIOSH) seal of 
approval. Cartridges or canisters must be replaced before the end of 
their service life, or the end of the shift, whichever occurs first. If 
you experience difficulty breathing while wearing a respirator, you may 
request a positive pressure respirator from your employer. You must be 
thoroughly trained to use the assigned respirator, and the training will 
be provided by your employer.
    (b) Protective clothing. You must wear appropriate protective 
clothing (such as boots, gloves, sleeves, and aprons) over any parts of 
your body that could be exposed to liquid benzene.
    (c) Eye and face protection. You must wear splash-proof safety 
goggles if it is possible that benzene may get into your eyes. In 
addition, you must wear a face shield if your face could be splashed 
with benzene liquid.

                 IV. Emergency and First Aid Procedures

    (a) Eye and face exposure. If benzene is splashed in your eyes, wash 
it out immediately with large amounts of water. If irritation persists 
or vision appears to be affected, see a doctor as soon as possible.
    (b) Skin exposure. If benzene is spilled on your clothing or skin, 
remove the contaminated clothing and wash the exposed skin with large 
amounts of water and soap immediately. Wash contaminated clothing before 
you wear it again.
    (c) Breathing. If you or any other person breathes in large amounts 
of benzene, get the exposed person to fresh air at once. Apply 
artificial respiration if breathing has stopped. Call for medical 
assistance or a doctor as soon as possible. Never enter any vessel or 
confined space where the benzene concentration might be high without 
proper safety equipment and with at least one other

[[Page 411]]

person present who will stay outside. A life line should be used.
    (d) Swallowing. If benzene has been swallowed and the subject is 
conscious, do not induce vomiting. Call for medical assistance or a 
doctor immediately.

                         V. Medical Requirements

    If you will be exposed to benzene at a concentration at or above 0.5 
ppm as an eight-hour time-weighted average or have been exposed at or 
above 10 ppm in the past while employed by your current employer, your 
employer may be required by 46 CFR 197.560 to provide a medical 
examination and history and laboratory tests. These tests must be 
provided without cost to you. In addition, if you are accidentally 
exposed to benzene (either by ingestion, inhalation, or skin/eye 
contact) under emergency conditions known or suspected to constitute a 
toxic exposure to benzene, your employer is required to make special 
laboratory tests available to you.

                      VI. Observation of Monitoring

    The employer is required to conduct monitoring that is 
representative of your exposure to benzene, and you or your designated 
representative are entitled to observe the monitoring procedure. You are 
entitled to observe the steps taken in the measurement procedure and to 
record the results obtained. When the monitoring procedure is taking 
place in an area where respirators or personal protective clothing and 
equipment are required to be worn, you or your representative must wear 
the protective clothing and equipment (See 46 CFR 197.575.)

                         VII. Access to Records

    You or your representative may see the records of monitoring of your 
exposure to benzene upon written request to your employer. Your medical 
examination records may be furnished to you, your physician, or a 
representative designated by you. (See 46 CFR 197.570(c).)

          VIII. Precautions for Safe Use, Handling, and Storage

    Benzene liquid is highly flammable. Benzene vapor may form explosive 
mixtures in air. All sources of ignition must be controlled. Use non-
sparking tools when opening or closing benzene containers. Fire 
extinguishers, where required, must be readily available. Know where 
they are located and how to operate them. Smoking is prohibited in areas 
where benzene is used or stored.



     Sec. Appendix B to Subpart C of Part 197--Substance Technical 
                           Guidelines, Benzene

                      I. Physical and Chemical Data

    (a) Substance identification. (1) Synonyms: Benzol, benzole, coal 
naphtha, cyclohexatriene, phene, phenyl hydride, pyrobenzol. (Benzin, 
petroleum benzin, and benzine do not contain benzene).
    (2) Formula: C6 H6 (CAS Registry Number: 71-
43-2).
    (b) Physical data. (1) Boiling point (760 mm Hg): 80.1 [deg]C (176 
[deg]F).
    (2) Specific gravity (water = 1): 0.879.
    (3) Vapor density (air = 1): 2.7.
    (4) Melting point: 5.5 [deg]C (42 [deg]F).
    (5) Vapor pressure at 20 [deg]C (68 [deg]F): 75 mm Hg.
    (6) Solubility in water: .06%.
    (7) Evaporation rate (ether = 1): 2.8.
    (8) Appearance and odor: Clear, colorless liquid with a distinctive 
sweet odor.

             II. Fire, Explosion, and Reactivity Hazard Data

    (a) Fire. (1) Flash point (closed cup): -11 [deg]C (12 [deg]F).
    (2) Autoignition temperature: 580 [deg]C (1076 [deg]F).
    (3) Flammable limits in air, % by volume: Lower: 1.3%, Upper: 7.5%.
    (4) Extinguishing media: Carbon dioxide, dry chemical, or foam.
    (5) Special fire fighting procedures: Do not use a solid stream of 
water, because it will scatter and spread the fire. Fine water spray may 
be used to keep fire-exposed containers cool.
    (6) Unusual fire and explosion hazards: Benzene is a flammable 
liquid. Its vapors can form explosive mixtures. All ignition sources 
must be controlled when benzene is used, handled, or stored. Areas where 
liquid or vapor may be released are considered hazardous locations. 
Benzene vapors are heavier than air. Thus, benzene vapors may travel 
along the deck and ground and be ignited by open flames or sparks at 
locations remote from the site at which benzene is handled.
    (7) Benzene is classified as a flammable liquid for the purpose of 
conforming to the requirements of 49 CFR 172.101 concerning the 
designation of materials as hazardous materials. Locations where benzene 
may be present in quantities sufficient to produce explosive or 
ignitable mixtures are considered Class I Group D locations for the 
purposes of conforming to the requirements of 46 CFR parts 30 through 
40, 151, and 153 when determining the requirements for electrical 
equipment as specified in Subchapter J (Electrical engineering).
    (b) Reactivity. (1) Conditions contributing to instability: Heat.
    (2) Incompatibility: Heat and oxidizing materials.

[[Page 412]]

    (3) Hazardous decomposition products: Toxic gases and vapors (such 
as carbon monoxide).

                     III. Spill and Leak Procedures

    (a) Steps to be taken if the material is released or spilled. As 
much benzene as possible should be absorbed with suitable materials, 
such as dry sand or earth. That remaining must be flushed with large 
amounts of water. Do not flush benzene into a confined space, such as a 
sewer, because of explosion danger. Remove all ignition sources. 
Ventilate enclosed places.
    (b) Waste disposal method. Disposal methods must conform to state 
and local regulations. If allowed, benzene may be disposed of (a) by 
absorbing it in dry sand or earth and disposing in a sanitary landfill, 
(b), if in small quantities, by removing it to a safe location away from 
buildings or other combustible sources or by pouring onto dry sand or 
earth and cautiously igniting it, and (c), if in large quantities, by 
atomizing it in a suitable combustion chamber.



     Sec. Appendix C to Subpart C of Part 197--Medical Surveillance 
                         Guidelines for Benzene

                            I. Route of Entry

    Inhalation; skin absorption.

                             II. Toxicology

    Benzene is primarily an inhalation hazard. Systemic absorption may 
cause depression of the hematopoietic system, pancytopenia, aplastic 
anemia, and leukemia. Inhalation of high concentrations may affect the 
functioning of the central nervous system. Aspiration of small amounts 
of liquid benzene immediately causes pulmonary edema and hemorrhage of 
pulmonary tissue. There is some absorption through the skin. Absorption 
may be more rapid in the case of abraded skin or if it is present in a 
mixture or as a contaminant in solvents which are readily absorbed. The 
defatting action of benzene may produce primary irritation due to 
repeated or prolonged contact with the skin. High concentrations are 
irritating to the eyes and the mucous membranes of the nose and 
respiratory tract.

                         III. Signs and Symptoms

    Direct skin contact with benzene may cause erythema. Repeated or 
prolonged contact may result in drying, scaling dermatitis or 
development of secondary skin infections. In addition, benzene is 
absorbed through the skin. Local effects of benzene vapor or liquid on 
the eye are slight. Only at very high concentrations is there any 
smarting sensation in the eye. Inhalation of high concentrations of 
benzene may have an initial stimulatory effect on the central nervous 
system characterized by exhilaration, nervous excitation, or giddiness, 
followed by a period of depression, drowsiness, or fatigue. A sensation 
of tightness in the chest accompanied by breathlessness may occur and 
ultimately the victim may lose consciousness. Tremors, convulsions, and 
death may follow from respiratory paralysis or circulatory collapse in a 
few minutes to several hours following severe exposures.
    The detrimental effect on the blood-forming system of prolonged 
exposure to small quantities of benzene vapor is of extreme importance. 
The hematopoietic system is the chief target for benzene's toxic effects 
which are manifested by alterations in the levels of formed elements in 
the peripheral blood. These effects may occur at concentrations of 
benzene which may not cause irritation of mucous membranes or any 
unpleasant sensory effects. Early signs and symptoms of benzene 
morbidity are varied. Often, they are not readily noticed and are non-
specific. Complaints of headache, dizziness, and loss of appetite may 
precede or follow clinical signs. Rapid pulse and low blood pressure, in 
addition to a physical appearance of anemia, may accompany a complaint 
of shortness of breath and excessive tiredness. Bleeding from the nose, 
gums, or mucous membranes and the development of purpuric spots (small 
bruises) may occur as the condition progresses. Clinical evidence of 
leukopenia, anemia, and thrombocytopenia, singly or in combination, may 
be among the first signs.
    Bone marrow may appear normal, aplastic, or hyperplastic and may 
not, in all situations, correlate with peripheral blood forming tissues. 
Because of variations in the susceptibility to benzene morbidity, there 
is no ``typical'' blood picture. The onset of effects of prolonged 
benzene exposure may be delayed for many months or years after the 
actual exposure has ceased. Identification or correlation with benzene 
exposure must be sought out in the occupational history.

                  IV. Treatment of Acute Toxic Effects

    Remove from exposure immediately. Make sure you are adequately 
protected and do not risk being overcome by fumes. Give oxygen or 
artificial resuscitation, if indicated. Flush eyes, wash skin if 
contaminated, and remove all contaminated clothing. Symptoms of 
intoxication may persist following severe exposures. Recovery from mild 
exposures is usually rapid and complete.

              V. Surveillance and Preventive Considerations

    (a) General. The principal effects of benzene exposure addressed in 
46 CFR part 197, subpart C, appendix A, are pathological changes in the 
hematopoietic system, reflected by changes in the peripheral blood and 
manifested clinically as pancytopenia, aplastic anemia, or leukemia. 
Consequently, the

[[Page 413]]

medical surveillance program specified in 46 CFR 197.560 is designed to 
observe, on a regular basis, blood indices for early signs of these 
effects. Although early signs of leukemia are not usually available, 
emerging diagnostic technology and innovative regimes are making 
consistent surveillance for leukemia, as well as other hematopoietic 
effects, more and more beneficial.
    Initial and periodic medical examinations must be provided as 
required in 46 CFR 197.560. There are special provisions for medical 
tests in the event of hematologic abnormalities or emergencies.
    The blood values which require referral to a hematologist or 
internist are noted in 46 CFR 197.560(d) (i), (ii), and (iii). That 
section specifies that, if blood abnormalities persist, the employee 
must be referred unless the physician has good reason to believe that 
the referral is unnecessary. Examples of conditions that might make a 
referral unnecessary despite abnormal blood limits are iron or folate 
deficiency, menorrhagia, or blood loss due to some unrelated medical 
abnormality.
    Symptoms and signs of benzene toxicity can be non-specific. Only a 
detailed history and appropriate investigative procedures will enable a 
physician to rule out or confirm conditions that place the employee at 
increased risk. To assist the examining physician with regard to which 
laboratory tests are necessary and when to refer an employee to the 
specialist, the following guidelines have been established.
    (b) Hematology Guidelines. A minimum battery of tests is to be 
performed by strictly standardized methods.
    (1) Red cell, white cell, platelet counts, white blood cell 
differential, hematocrit, and red cell indices must be performed by an 
accredited laboratory. The normal ranges for the red cell and white cell 
counts are influenced by altitude, race, and sex and, therefore, should 
be determined by an accredited laboratory in the specific area where the 
tests are performed.
    Either a decline from an absolute normal or from an individual's 
base line to a subnormal value or a rise to a supra-normal value are 
indicative of potential toxicity, particularly if all blood parameters 
decline. The normal total white blood count is approximately 7,200/mm 
\3\ plus or minus 3,000. For cigarette smokers, the white count may be 
higher and the upper range may be 2,000 cells higher than normal for the 
laboratory. In addition, infection, allergies, and some drugs may raise 
the white cell count. The normal platelet count is approximately 250,000 
with a range of 140,000 to 400,000. Counts outside this range should be 
regarded as possible evidence of benzene toxicity.
    Certain abnormalities found through routine screening are of greater 
significance in the benzene-exposed worker and require prompt 
consultation with a specialist, namely:
    (i) Thrombocytopenia.
    (ii) A trend of decreasing white cell, red cell, or platelet indices 
in an individual over time is more worrisome than an isolated abnormal 
finding at one test time. The importance of a trend highlights the need 
to compare an individual's test results to baseline, to previous 
periodic tests, or to both.
    (iii) A constellation or pattern of abnormalities in the different 
blood indices is of more significance than a single abnormality. A low 
white count not associated with any abnormalities in other cell indices 
may be a normal statistical variation. Whereas, if the low white count 
is accompanied by decreases in the platelet and/or red cell indices, 
such a pattern is more likely to be associated with benzene toxicity and 
merits thorough investigation.
    Anemia, leukopenia, macrocytosis, or an abnormal differential white 
blood cell count should alert the physician to investigate further and 
to refer the patient if repeat tests confirm the abnormalities. If 
routine screening detects an abnormality, the follow-up tests which may 
be helpful in establishing the etiology of the abnormality are the 
peripheral blood smear and the reticulocyte count.
    The extreme range of normal for reticulocytes is 0.4 to 2.5 percent 
of the red cells. The usual range is 0.5 to 1.2 percent of the red 
cells. A decline in reticulocytes to levels of less than 0.4 percent is 
to be regarded as possible evidence of benzene toxicity requiring 
accelerated surveillance (unless another specific cause is found). An 
increase in reticulocyte levels to above 2.5 percent also may be 
consistent with, but not characteristic of, benzene toxicity.
    (2) A careful examination of the peripheral blood smear is an 
important diagnostic test. As with the reticulocyte count, the smear 
should be with fresh uncoagulated blood obtained from a needle tip 
following venipuncture or from a drop of earlobe blood (capillary 
blood). If necessary, the smear may, under certain limited conditions, 
be made from a blood sample anticoagulated with EDTA (but never with 
oxalate or heparin). When the smear is to be prepared from a specimen of 
venous blood which has been collected by a commercial Vacutainer 
[supreg] type tube containing neutral EDTA, the smear should be made as 
soon as possible after the venesection. A delay of up to 12 hours is 
permissible between the drawing of the blood specimen into EDTA and the 
preparation of the smear if the blood is stored at refrigerator (not 
freezing) temperature.
    (3) The minimum mandatory observations to be made from the smear are 
as follows:
    (i) The differential white blood cell count.
    (ii) Description of abnormalities in the appearance of red cells.

[[Page 414]]

    (iii) Description of any abnormalities in the platelets.
    (iv) A careful search must be made of every blood smear for immature 
white cells such as band forms (in more than normal proportion, i.e., 
over ten percent of the total differential count), any number of 
metamyelocytes, myelocytes, or myeloblasts. Any nucleate or 
multinucleated red blood cells should be reported. Large ``giant'' 
platelets or fragments of megakaryocytes must be recognized.
    An increase in the proportion of band forms among the neutrophilic 
granulocytes is an abnormality deserving special mention. Such an 
increase may represent a change which should be considered as an early 
warning of benzene toxicity in the absence of other causative factors 
(most commonly infection). Likewise, the appearance of metamyelocytes, 
in the absence of another probable cause, is to be considered a possible 
indication of benzene-induced toxicity.
    An upward trend in the number of basophils, which normally do not 
exceed about 2.0 percent of the total white cells, is to be regarded as 
possible evidence of benzene toxicity. A rise in the eosinophil count is 
less specific but may indicate toxicity if the rise is above 6.0 percent 
of the total white count.
    The normal range of monocytes is from 2.0 to 8.0 percent of the 
total white count with an average of about 5.0 percent. About 20 percent 
of individuals reported to have mild but persisting abnormalities caused 
by exposure to benzene show a persistent monocytosis. The findings of a 
monocyte count which persists at more than ten to 12 percent of the 
normal white cell count (when the total count is normal) or persistence 
of an absolute monocyte count in excess of 800/mm \3\ should be regarded 
as a possible sign of benzene-induced toxicity.
    A less frequent but more serious indication of benzene toxicity is 
the finding in the peripheral blood of the so-called ``pseudo'' (or 
acquired) Pelger-Huet anomaly. In this anomaly, many, or sometimes the 
majority, of the neutrophilic granulocytes possess two round nuclear 
segments, or, less often, one or three round segments, rather than three 
normally elongated segments. When this anomaly is not hereditary, it is 
often, but not invariably, predictive of subsequent leukemia. However, 
only about two percent of patients who ultimately develop acute 
myelogenous leukemia show the acquired Pelger-Huet anomaly. Other tests 
that can be administered to investigate blood abnormalities are 
discussed below. However, these tests should be undertaken by the 
hematologist.
    An uncommon sign, which cannot be detected from the smear but can be 
elicited by a ``sucrose water test'' of peripheral blood, is transient 
paroxysmal nocturnal hemoglobinuria (PNH). This sign may first occur 
insidiously during a period of established aplastic anemia and may be 
followed within one to a few years by the appearance of rapidly fatal, 
acute myelogenous leukemia. Clinical detection of PNH, which occurs in 
only one or two percent of those destined to have acute myelogenous 
leukemia, may be difficult. If the ``sucrose water test'' is positive, 
the somewhat more definitive Ham test, also known as the acid-serum 
hemolysis test, may provide confirmation.
    (v) Individuals documented to have developed acute myelogenous 
leukemia years after initial exposure to benzene may have progressed 
through a preliminary phase of hematologic abnormality. In some 
instances, pancytopenia (i.e., a lowering in the counts of all 
circulating blood cells of bone marrow origin, but not to the extent 
implied by the term ``aplastic anemia'') preceded leukemia for many 
years. Depression of a single blood cell type or platelets may represent 
a harbinger of aplasia or leukemia. The finding of two or more 
cytopenias or pancytopenia in a benzene-exposed individual must be 
regarded as highly suspicious of more advanced, although still 
reversible, toxicity. Pancytopenia coupled with the appearance of 
immature cells (myelocytes, myeloblasts, erythroblasts, etc.) with 
abnormal cells (pseudo Pelger-Huet anomaly, atypical nuclear 
heterochromatin, etc.) or of unexplained elevations of white blood cells 
must be regarded as evidence of benzene overexposure, unless proved 
otherwise. Many severely aplastic patients manifested the ominous 
finding of five to ten percent myeloblasts in the marrow, occasional 
myeloblasts and myelocytes in the blood, and 20 to 30 percent monocytes. 
It is evident that isolated cytopenias, pancytopenias, and even aplastic 
anemias induced by benzene may be reversible and complete recovery has 
been reported on cessation of exposure. However, because any of these 
abnormalities is serious, the employee must immediately be removed from 
any possible exposure to benzene vapor. Certain tests may substantiate 
the employee's prospects for progression or regression. One such test 
would be an examination of the bone marrow, but the decision to perform 
a bone marrow aspiration or needle biopsy must be made by the 
hematologist.
    The findings of basophilic stippling in circulating red blood cells 
(usually found in one to five percent of red cells following marrow 
injury) and detection in the bone marrow of what are termed ``ringed 
sideroblasts'' must be taken seriously, as they have been noted in 
recent years to be premonitory signs of subsequent leukemia.
    Recently peroxidase-staining of circulating or marrow neutrophil 
granulocytes, employing benzidine dihydrochloride, have revealed the 
disappearance of, or diminution in, peroxidase in a sizable proportion 
of the granulocytes. This has been reported as an

[[Page 415]]

early sign of leukemia. However, relatively few patients have been 
studied to date. Granulocyte granules are normally strongly peroxidase 
positive. A steady decline in leukocyte alkaline phosphatase has also 
been reported as suggestive of early acute leukemia. Exposure to benzene 
may cause an early rise in serum iron, often but not always associated 
with a fall in the reticulocyte count. Thus, serial measurements of 
serum iron levels may provide a means of determining whether or not 
there is a trend representing sustained suppression of erythropoiesis.
    Measurement of serum iron and determination of peroxidase and of 
alkaline phosphatase activity in peripheral granulocytes can be 
performed in most pathology laboratories. Peroxidase and alkaline 
phosphatase staining are usually undertaken when the index of suspicion 
for leukemia is high.



   Sec. Appendix D to Subpart C of Part 197--Sampling and Analytical 
         Methods for Benzene Monitoring--Measurement Procedures

    Measurements taken for the purpose of determining employee exposure 
to benzene are best taken so that the representative average eight-hour 
exposure may be determined from a single eight-hour sample or two four-
hour samples. Short-time interval samples (or grab samples) may also be 
used to determine average exposure level if a minimum of five 
measurements are taken in a random manner over the eight-hour work 
shift. In random sampling, any portion of the work shift has the same 
chance of being sampled as any other. The arithmetic average of all 
random samples taken on one work shift is an estimate of an employee's 
average level of exposure for that work shift. Air samples should be 
taken in the employee's breathing zone (i.e., air that would most nearly 
represent that inhaled by the employee). Sampling and analysis must be 
performed with procedures meeting the requirements of 46 CFR part 197, 
subpart C.
    There are a number of methods available for monitoring employee 
exposures to benzene. The sampling and analysis may be performed by 
collection of the benzene vapor on charcoal adsorption tubes, with 
subsequent chemical analysis by gas chromatography. Sampling and 
analysis also may be performed by portable direct reading instruments, 
real-time continuous monitoring systems, passive dosimeters, or other 
suitable methods. The employer is required to select a monitoring method 
which meets the accuracy and precision requirements of 46 CFR 
197.540(a)(6) for the weather conditions expected. Section 197.540(a)(6) 
requires that monitoring must have an accuracy, to a 95 percent 
confidence level, of not less than plus or minus 25 percent for 
concentrations of benzene greater than or equal to 0.5 ppm.
    In developing the following analytical procedures, the OSHA 
Laboratory modified NIOSH Method S311 and evaluated it at a benzene air 
concentration of one ppm. A procedure for determining the benzene 
concentration in bulk material samples was also evaluated. This work, as 
reported in OSHA Laboratory Method No. 12, includes the following two 
analytical procedures:

                    I. OSHA Method 12 for Air Samples

    Analyte: Benzene.
    Matrix: Air.
    Procedure: Adsorption on charcoal, desorption with carbon disulfide, 
analysis by gas chromatograph.
    Detection limit: 0.04 ppm.
    Recommended air volume and sampling rate: 10 liter at 0.2 liter/min.

                       1. Principle of the method

    1.1. A known volume of air is drawn through a charcoal tube to trap 
the organic vapors present.
    1.2. The charcoal in the tube is transferred to a small, stoppered 
vial and the analyte is desorbed with carbon disulfide.
    1.3. An aliquot of the desorbed sample is injected into a gas 
chromatograph.
    1.4. The area of the resulting peak is determined and compared with 
areas obtained from standards.

              2. Advantages and disadvantages of the method

    2.1. The sampling device is small, portable, and involves no 
liquids. Interferences are minimal and most of those which do occur can 
be eliminated by altering chromatographic conditions. The samples are 
analyzed by means of a quick, instrumental method.
    2.2. The amount of sample which can be taken is limited by the 
number of milligrams that the tube will hold before overloading. When 
the sample value obtained for the backup section of the charcoal tube 
exceeds 25 percent of that found on the front section, the possibility 
of sample loss exists.

                              3. Apparatus

    3.1. A calibrated personal sampling pump having a flow that can be 
determined within five percent at the recommended 
flow rate.
    3.2. Charcoal tubes: Glass with both ends flame sealed, seven cm 
long with a six mm O.D. and a four mm I.D., containing two sections of 
20/40 mesh activated charcoal separated by a two mm portion of urethane 
foam. The activated charcoal is prepared from coconut shells and is 
fired at 600 [deg]C before packing. The adsorbing section contains 100 
mg of charcoal and the back-up section 50

[[Page 416]]

mg. A three mm portion of urethane foam is placed between the outlet end 
of the tube and the back-up section. A plug of silanized glass wool is 
placed in front of the adsorbing section. The pressure drop across the 
tube must be less than one inch of mercury at a flow rate of one liter 
per minute.
    3.3. Gas chromatograph equipped with a flame ionization detector.
    3.4. Column (10 ft. x \1/8\ in. stainless steel) packed with 80/100 
Supelcoport coated with 20 percent SP 2100 and 0.1 percent CW 1500.
    3.5. An electronic integrator or some other suitable method for 
measuring peak area.
    3.6. Two-milliliter sample vials with Teflon-lined caps.
    3.7. Microliter syringes: ten microliter (ten [micro]l) syringe, and 
other convenient sizes for making standards. One [micro]l syringe for 
sample injections.
    3.8. Pipets: 1.0 ml delivery pipets.
    3.9. Volumetric flasks: convenient sizes for making standard 
solutions.

                               4. Reagents

    4.1. Chromatographic quality carbon disulfide (CS2). Most 
commercially available carbon disulfide contains a trace of benzene 
which must be removed. It can be removed with the following procedure. 
Heat, under reflux for two to three hours, 500 ml of carbon disulfide, 
ten ml concentrated sulfuric acid, and five drops of concentrated nitric 
acid. The benzene is converted to nitrobenzene. The carbon disulfide 
layer is removed, dried with anhydrous sodium sulfate, and distilled. 
The recovered carbon disulfide should be benzene free. (It has recently 
been determined that benzene can also be removed by passing the carbon 
disulfide through a 13x molecular sieve).
    4.2. Benzene, reagent grade.
    4.3. p-Cymene, reagent grade, (internal standard).
    4.4. Desorbing reagent. The desorbing reagent is prepared by adding 
0.05 ml of p-cymene per milliliter of carbon disulfide. (The internal 
standard offers a convenient means correcting analytical response for 
slight inconsistencies in the size of sample injections. If the external 
standard technique is preferred, the internal standard can be 
eliminated.)
    4.5. Purified GC grade helium, hydrogen, and air.

                              5. Procedure

    5.1. Cleaning of equipment. All glassware used for the laboratory 
analysis should be properly cleaned and free of organics which could 
interfere in the analysis.
    5.2. Calibration of personal pumps. Each pump must be calibrated 
with a representative charcoal tube in the line.
    5.3. Collection and shipping of samples.
    5.3.1. Immediately before sampling, break the ends of the tube to 
provide an opening at least one-half the internal diameter of the tube 
(two mm).
    5.3.2. The smaller section of the charcoal is used as the backup and 
should be placed nearest the sampling pump.
    5.3.3. The charcoal tube should be placed in a vertical position 
during sampling to minimize channeling through the charcoal.
    5.3.4. Air being sampled should not be passed through any hose or 
tubing before entering the charcoal tube.
    5.3.5. A sample size of 10 liters is recommended. Sample at a flow 
rate of approximately 0.2 liters per minute. The flow rate should be 
known with an accuracy of at least five percent.
    5.3.6. The charcoal tubes should be capped with the supplied plastic 
caps immediately after sampling.
    5.3.7. Submit at least one blank tube (a charcoal tube subjected to 
the same handling procedures, without having any air drawn through it) 
with each set of samples.
    5.3.8. Take necessary shipping and packing precautions to minimize 
breakage of samples.
    5.4. Analysis of samples.
    5.4.1. Preparation of samples. In preparation for analysis, each 
charcoal tube is scored with a file in front of the first section of 
charcoal and broken open. The glass wool is removed and discarded. The 
charcoal in the first (larger) section is transferred to a two ml vial. 
The separating section of foam is removed and discarded and the second 
section is transferred to another capped vial. These two sections are 
analyzed separately.
    5.4.2. Desorption of samples. Before analysis, 1.0 ml of desorbing 
solution is pipetted into each sample container. The desorbing solution 
consists of 0.05 [micro]l internal standard per milliliter of carbon 
disulfide. The sample vials are capped as soon as the solvent is added. 
Desorption should be done for 30 minutes with occasional shaking.
    5.4.3. GC conditions. Typical operating conditions for the gas 
chromatograph are as follows:
    1. 30 ml/min (60 psig) helium carrier gas flow.
    2. 30 ml/min (40 psig) hydrogen gas flow to detector.
    3. 240 ml/min (40 psig) air flow to detector.
    4. 150 [deg]C injector temperature.
    5. 250 [deg]C detector temperature.
    6. 100 [deg]C column temperature.
    5.4.4. Injection size. One [micro]l.
    5.4.5. Measurement of area. The peak areas are measured by an 
electronic integrator or some other suitable form of area measurement.
    5.4.6. An internal standard procedure is used. The integrator is 
calibrated to report results in ppm for a 10 liter air sample after 
correction for desorption efficiency.

[[Page 417]]

    5.5. Determination of desorption efficiency.
    5.5.1. Importance of determination. The desorption efficiency of a 
particular compound may vary from one laboratory to another and from one 
lot of chemical to another. Thus, it is necessary to determine, at least 
once, the percentage of the specific compound that is removed in the 
desorption process, provided the same batch of charcoal is used.
    5.5.2. Procedure for determining desorption efficiency. The 
reference portion of the charcoal tube is removed. To the remaining 
portion, amounts representing 0.5X, 1X, and 2X (X represents target 
concentration) based on a 10 liter air sample, are injected into several 
tubes at each level. Dilutions of benzene with carbon disulfide are made 
to allow injection of measurable quantities. These tubes are then 
allowed to equilibrate at least overnight. Following equilibration, they 
are analyzed following the same procedure as the samples. Desorption 
efficiency is determined by dividing the amount of benzene found by 
amount spiked on the tube.

                      6. Calibration and standards

    A series of standards varying in concentration over the range of 
interest is prepared and analyzed under the same GC conditions that will 
be used on the samples. A calibration curve is prepared by plotting 
concentration ([micro]g/ml) versus peak area.

                             7. Calculations

    Benzene air concentration can be calculated from the following 
equation:

mg/m\3\ = (A)(B)/(C)(D)

Where:
A=[micro]g/ml benzene, obtained from the calibration curve; B = 
          desorption volume (one ml); C = liters of air sampled; and D = 
          desorption efficiency.

    The concentration in mg/m\3\ can be converted to ppm (at 25[deg] and 
760 mm) with following equation:

ppm = (mg/m\3\)(24.46)/(78.11).

Where:
24.46 = molar volume of an ideal gas 25 [deg]C and 760 mm; and 78.11 = 
          molecular weight of benzene.

                             8. Backup data

    8.1 Detection limit--Air Samples. The detection limit for the 
analytical procedure is 1.28 ng with a coefficient of variation of 0.023 
at this level. This would be equivalent to an air concentration of 0.04 
ppm for a 10 liter air sample. This amount provided a chromatographic 
peak that could be identifiable in the presence of possible 
interferences. The detection limit data were obtained by making one 
[micro]l injections of a 1.283 [micro]g/ml standard.

    8.2 Pooled coefficient of variation--Air Samples. The pooled 
coefficient of variation for the analytical procedure was determined by 
one [micro]l replicate injections of analytical standards. The standards 
were 16.04, 32.08, and 64.16 [micro]g/ml, which are equivalent to 0.5, 
1.0, and 2.0 ppm for a 10 liter air sample respectively.
    8.3 Storage data--Air Samples. Samples were generated at 1.03 ppm 
benzene at 80% relative humidity, 22 [deg]C, and 643 mm. All samples 
were taken for 50 minutes at 0.2 liters/min. Six samples were analyzed 
immediately and the rest of the samples were divided into two groups by 
fifteen samples each. One group was stored at refrigerated temperature 
of -25 [deg]C and the other group was stored at ambient temperature 
(approximately 23 [deg]C). These samples were analyzed over a period of 
fifteen days. The results are tabulated below.

           II. OSHA Laboratory Method No. 12 for Bulk Samples

    Analyte: Benzene.
    Matrix: Bulk Samples.
    Procedure: Bulk samples are analyzed directly by high performance 
liquid chromatography (HPLC).
    Detection limits: 0.01% by volume.

                       1. Principle of the method

    1.1. An aliquot of the bulk sample to be analyzed is injected into a 
liquid chromatograph.
    1.2. The peak area for benzene is determined and compared to areas 
obtained from standards.

              2. Advantages and disadvantages of the method

    2.1. The analytical procedure is quick, sensitive, and reproducible.
    2.2. Reanalysis of samples is possible.
    2.3. Interferences can be circumvented by proper selection of HPLC 
parameters.
    2.4. Samples must be free of any particulates that may clog the 
capillary tubing in the liquid chromatograph. This may require 
distilling the sample or clarifying with a clarification kit.

                              3. Apparatus

    3.1. Liquid chromatograph equipped with a UV detector.
    3.2. HPLC Column that will separate benzene from other components in 
the bulk sample being analyzed. The column used for validation studies 
was a Waters uBondapack C18, 30 cm x 3.9 mm.
    3.3. A clarification kit to remove any particulates in the bulk if 
necessary.
    3.4. A micro-distillation apparatus to distill any samples if 
necessary.
    3.5. An electronic integrator or some other suitable method of 
measuring peak areas.
    3.6. Microliter syringes--ten [micro]l syringe and other convenient 
sizes for making standards. 10 [micro]l syringe for sample injections.
    3.7. Volumetric flasks, five ml and other convenient sizes for 
preparing standards and making dilutions.

                               4. Reagents

    4.1. Benzene, reagent grade.
    4.2. HPLC grade water, methyl alcohol, and isopropyl alcohol.

                  5. Collection and shipment of samples

    5.1. Samples should be transported in glass containers with Teflon-
lined caps.
    5.2. Samples should not be put in the same container used for air 
samples

                         6. Analysis of samples

    6.1. Sample preparation. If necessary, the samples are distilled or 
clarified. Samples are analyzed undiluted. If the benzene concentration 
is out of the working range, suitable dilutions are made with isopropyl 
alcohol.
    6.2. HPLC conditions. The typical operating conditions for the high 
performance liquid chromatograph are:

[[Page 419]]

    6.2.1. Mobile phase--Methyl alcohol/water, 50/50.
    6.2.2. Analytical wavelength--254 nm.
    6.2.3. Injection size--10 [micro]l.
    6.3. Measurement of peak area and calibration. Peak areas are 
measured by an integrator or other suitable means. The integrator is 
calibrated to report results in % benzene by volume.

                             7. Calculations

    Because the integrator is programmed to report results in % benzene 
by volume in an undiluted sample, the following equation is used: % 
Benzene by Volume = A x B.
    Where: A = % by volume on report. B = Dilution Factor. (B = one for 
undiluted sample).

                             8. Backup data

    8.1. Detection limit--Bulk Samples. The detection limit for the 
analytical procedure for bulk samples is 0.88 [micro]g, with a 
coefficient of variation of 0.019 at this level. This amount provided a 
chromatographic peak that could be identifiable in the presence of 
possible interferences. The detection limit date were obtained by making 
ten [micro]l injections of a 0.10% by volume standard.

     Sec. Appendix E to Subpart C of Part 197--Respirator Fit Tests

                               Procedures

    This appendix contains the procedures for properly fitting a 
respirator to employees who may be exposed to benzene and includes the 
Initial Fit Tests (IFT), the Qualitative Fit Tests (QLFT), and the 
Quantitative Fit Test (QNFT).
    Note that respirators (negative pressure or positive pressure) must 
not be worn when conditions prevent a tight seal between the faceplate 
and the skin or the proper functioning of the inhalation or exhalation 
valves. In order for a respirator to protect the wearer, the facepiece 
must make a proper seal against the wearer's face. Several factors can 
negatively affect the respirator to face seal and reduce the level of 
protection afforded by the respirator. Among these are facial shape, 
temple pieces of eyeglasses, facial abnormalities (e.g., scars and 
indentations) absence of dentures, hair style or length of hair, 
specific skin conditions, and facial hair. Therefore, nothing can come 
between or otherwise interfere with the sealing surface of the 
respirator and the face or interfere with the function of the inhalation 
or exhalation valves.

                       I. Initial Fit Tests (IFT)

    (a) The test subject must be allowed to select the most comfortable 
respirator from a selection of respirators of various sizes. The 
selection must include at least three sizes of elastomeric facepieces 
for the type of respirator that is to be tested (i.e., three sizes of 
half mask or three sizes of full facepiece).
    (b) Before the selection process, the test subject must be shown how 
to put on a respirator, how it should be positioned on the face, how to 
set strap tension, and how to determine a comfortable fit. A mirror must 
be available to assist the subject in evaluating the fit and positioning 
the respirator. This instruction is only a preliminary review and must 
not constitute the subject's formal training on respirator use.
    (c) The test subject must be informed that he or she is being asked 
to select the respirator which provides the most comfortable fit. Each 
respirator represents a different size and shape and, if fitted and used 
properly, should provide adequate protection.

[[Page 420]]

    (d) The test subject must be instructed to hold each facepiece up to 
the face and eliminate those facepieces which obviously do not give a 
comfortable fit.
    (e) The more comfortable facepieces must be noted and the most 
comfortable mask donned and worn at least five minutes to assess 
comfort. Assistance in assessing comfort may be given by discussing the 
points in section I(f) of this appendix. If the test subject is not 
familiar with using a particular respirator, the test subject must be 
directed to don the mask several times and to adjust the straps each 
time to become adept at setting proper tension on the straps.
    (f) Assessment of comfort must include reviewing the following 
points with the test subject and allowing the test subject adequate time 
to determine the comfort of the respirator:
    (1) Position of the mask on the nose.
    (2) Room for eye protection.
    (3) Room to talk.
    (4) Position of mask on face and cheeks.
    (g) The following criteria must be used to help determine the 
adequacy of the respirator fit:
    (1) Chin properly placed.
    (2) Adequate strap tension, not overly tightened.
    (3) Fit across nose bridge.
    (4) Respirator of proper size to span distance from nose to chin.
    (5) Tendency of respirator to slip.
    (6) Self-observation in mirror to evaluate fit and respirator 
position.
    (h) The following negative and positive pressure fit tests must be 
conducted. Before conducting a negative or positive pressure fit test, 
the subject must be told to seat the mask on the face by moving the head 
from side-to-side and up and down slowly while taking in a few slow deep 
breaths Another facepiece must be selected and retested if the test 
subject fails the fit check tests.
    (1) Positive pressure fit test. The exhalation valve must be closed 
off and the subject must exhale gently onto the facepiece. The face fit 
is considered satisfactory if a slight positive pressure can be built up 
inside the facepiece without any evidence of outward leakage of air at 
the seal. For most respirators this method of leak testing requires the 
wearer to first remove the exhalation valve cover before closing off the 
exhalation valve and then carefully replacing it after the test.
    (2) Negative pressure fit test. The inlet opening of the canister or 
cartridge(s) must be closed off by covering with the palm of the hand(s) 
or by replacing the filter seal(s). The subject must inhale gently so 
that the facepiece collapses slightly and hold his or her breath for ten 
seconds. If the facepiece remains in its slightly collapsed condition 
and no inward leakage of air is detected, the tightness of the 
respirator is considered satisfactory.
    (i) The test must not be conducted if the subject has any hair 
growth between the skin and the facepiece sealing surface, such as 
stubble beard growth, beard, or long sideburns which cross the 
respirator sealing surface. Any type of apparel, such as a skull cap or 
the temple bars of eye glasses, which projects under the facepiece or 
otherwise interferes with a satisfactory fit must be altered or removed.
    (j) If the test subject exhibits difficulty in breathing during the 
tests, the subject must be referred to a physician trained in 
respiratory disease or pulmonary medicine to determine whether the test 
subject can wear a respirator while performing his or her duties.
    (k) The test subject must be given the opportunity to wear the 
successfully fitted respirator for a period of two weeks. If at any time 
during this period the respirator becomes uncomfortable, the test 
subject must be given the opportunity to select a different facepiece 
and to be retested.
    (l) Exercise regimen. Before beginning the fit test, the test 
subject must be given a description of the fit test and of the test 
subject's responsibilities during the test procedure. The description of 
the process must include a description of the test exercises that the 
subject must perform. The respirator to be tested must be worn for at 
least five minutes before the start of the fit test.
    (m) Test Exercises. The test subject must perform the following 
exercises in the test environment:
    (1) Normal breathing. In a normal standing position, without 
talking, the subject must breathe normally.
    (2) Deep breathing. In a normal standing position, the subject must 
breathe slowly and deeply, taking caution so as to not hyperventilate.
    (3) Turning head side to side. Standing in place, the subject must 
slowly turn his or her head from side to side between the extreme 
positions on each side. The subject must hold his or her head at each 
extreme momentarily and inhale.
    (4) Moving head up and down. Standing in place, the subject must 
slowly move his or her head up and down. The subject must be instructed 
to inhale in the up position (i.e., when looking toward the ceiling).
    (5) Talking. The subject must talk slowly and loudly enough so as to 
be heard clearly by the test conductor. The subject must count backward 
from 100, recite a memorized poem or song, or read the following 
passage:

                             Rainbow Passage

    When the sunlight strikes raindrops in the air, they act like a 
prism and form a rainbow. The rainbow is a division of white light into 
many beautiful colors. These take the

[[Page 421]]

shape of a long round arch, with its path high above, and its two ends 
apparently beyond the horizon. There is, according to legend, a boiling 
pot of gold at one end. People look, but no one ever finds it. When a 
man looks for something beyond reach, his friends say he is looking for 
the pot of gold at the end of the rainbow.

    (6) Grimace. The test subject must grimace by smiling or frowning.
    (7) Bending over. The test subject must bend at the waist as if to 
touch the toes or, for test environments such as shroud type QNFT units 
which prohibit bending at the waist, the subject must jog in place.
    (8) Normal breathing. Same as exercise 1.
    Each test exercise must be performed for one minute, except for the 
grimace exercise which must be performed for 15 seconds. The test 
subject must be questioned by the test conductor regarding the comfort 
of the respirator upon completion of test exercises. If it has become 
uncomfortable, another respirator must be tried and the subject 
retested.
    (n) The employer shall certify that a successful fit test has been 
administered to the test subject. The certification must include the 
following information:
    (1) Name of employee.
    (2) Type, brand, and size of respirator.
    (3) Date of test.
    Where QNFT is used, the fit factor, strip chart, or other recording 
of the results of the test must be retained with the certification. The 
certification must be maintained until the next fit test is 
administered.

                    II. Qualitative Fit Tests (QLFT)

    (a) General. (1) The employer shall designate specific individuals 
to administer the respirator qualitative fit test program. The employer 
may contract for these services.
    (2) The employer shall ensure that persons administering QLFT are 
able to properly prepare test solutions, calibrate equipment, perform 
tests, recognize invalid tests, and determine whether the test equipment 
is in proper working order.
    (3) The employer shall ensure that QLFT equipment is kept clean and 
maintained so as to operate at the parameters for which it was designed.
    (b) Isoamyl acetate tests. (1) Odor threshold screening test. The 
odor threshold screening test, performed without wearing a respirator, 
is intended to determine if the test subject can detect the odor of 
isoamyl acetate.
    (i) Three one-liter glass jars with metal lids must be used.
    (ii) Odor free water (e.g. distilled or spring water) at 
approximately 25 degrees C must be used for the solutions.
    (iii) An isoamyl acetate (IAA) (also known at isopentyl acetate) 
stock solution must be prepared by adding one cc of pure IAA to 800 cc 
of odor free water in a one liter jar and by shaking the jar for 30 
seconds. A new solution must be prepared at least weekly.
    (iv) The screening test must be conducted in a room separate from 
the room used for actual fit testing. The two rooms must be well 
ventilated but not connected to the same recirculating ventilation 
system.
    (v) An odor test solution must be prepared in a second one-liter jar 
by placing 0.4 cc of the stock solution into 500 cc of odor free water 
using a clean dropper or pipette. The solution must be shaken for 30 
seconds and allowed to stand for two to three minutes so that the IAA 
concentration above the liquid may reach equilibrium. This solution must 
be used for only one day.
    (vi) A test blank must be prepared in a third one-liter jar by 
adding 500 cc of odor free water.
    (vii) The odor test jar and the test blank jar must be labeled ``1'' 
and ``2'' for identification. The labels must be placed on the jar lids 
so that the labels can be periodically peeled off dried, and switched to 
maintain the integrity of the test.
    (viii) The following instruction must be typed on a card and placed 
on a table in front of the odor test jar and the test blank jar:

    The purpose of this test is to determine if you can smell banana oil 
at a low concentration. The two bottles in front of you contain water. 
One of these bottles also contains a small amount of banana oil. Be sure 
the covers are on tight, then shake each bottle for two seconds. Unscrew 
the lid of each bottle, one at a time, and sniff at the mouth of the 
bottle. Indicate to the test conductor which bottle contains banana oil.
    (ix) The mixtures in the jars used in the IAA odor threshold 
screening must be prepared in an area separate from the test area, in 
order to prevent olfactory fatigue in the test subject.
    (x) If the test subject is unable to correctly identify the jar 
containing the odor test solution, the IAA qualitative fit test must not 
be performed.
    (xi) If the test subject correctly identifies the jar containing the 
odor test solution, the test subject may proceed to respirator selection 
and fit testing.
    (2) Isoamyl acetate fit test. (i) The fit test chamber must be a 
clear 55-gallon drum liner or similar device suspended inverted over a 
two foot diameter frame so that the top of the chamber is about six 
inches above the test subject's head. The inside top center of the 
chamber must have a small hook attached.
    (ii) Each respirator used for the fitting and fit testing must be 
equipped with organic vapor cartridges or offer protection against

[[Page 422]]

organic vapors. The cartridges or masks must be changed at least weekly.
    (iii) After selecting, donning, and properly adjusting a respirator, 
the test subject must wear the respirator to the fit testing room. This 
room must be separate from the room used for odor threshold screening 
and respirator selection and must be well ventilated by an exhaust fan, 
lab hood, or other device to prevent general room contamination.
    (iv) A copy of the test exercises and any prepared text from which 
the subject is to read must be taped to the inside of the test chamber.
    (v) Upon entering the test chamber, the test subject must be given a 
six inch by five inch piece of paper towel or other porous, absorbent, 
single-ply material, folded in half and wetted with 0.75 cc of pure IAA. 
The test subject must hang the wet towel on the hook at the top of the 
chamber.
    (vi) Two minutes must be allowed for the IAA test concentration to 
stabilize before starting the fit test exercises. This would be an 
appropriate time to talk with the test subject, to explain the fit test, 
the importance of the subject's cooperation, and the purpose for the 
head exercises, or to demonstrate some of the exercises.
    (vii) The test subject must be instructed to perform the exercises 
described in section I(n) of this appendix. If at any time during the 
test the subject detects the banana like odor of IAA, the test is 
failed. The subject must be removed quickly from the test chamber and 
the test area to avoid olfactory fatigue.
    (viii) If the test is failed, the subject must return to the 
selection room, remove the respirator, repeat the odor sensitivity test, 
select and don another respirator, return to the test chamber, and again 
take the IAA fit test. The process must continue until a respirator that 
fits well is found. If the odor sensitivity test is failed, the subject 
must wait at least five minutes before retesting to allow odor 
sensitivity to return.
    (ix) When a respirator is found that passes the test, the subject 
must demonstrate the efficiency of the respirator by breaking the face 
seal and taking a breath before exiting the chamber. If the subject 
cannot detect the odor of IAA, the test is deemed inconclusive and must 
be rerun.
    (x) When the test subject leaves the chamber, the subject must 
remove the saturated towel and return it to the person conducting the 
test. To keep the test area from becoming contaminated, the used towel 
must be kept in a self-sealing bag to avoid significant IAA 
concentration build-up in the test chamber for subsequent tests.
    (c) Saccharin solution aerosol test. The saccharin solution aerosol 
test is an alternative qualitative test. Although it is the only 
validated test currently available for use with particulate disposable 
dust respirators not equipped with high-efficiency filters, it may also 
be used for testing other respirators. The entire screening and testing 
procedure must be explained to the test subject before the conduct of 
the saccharin test threshold screening test.
    (1) Saccharin taste threshold screening test. The test, performed 
without wearing a respirator, is intended to determine whether the test 
subject can detect the taste of saccharin.
    (i) The subject must wear an enclosure about the head and shoulders 
that is approximately 12 inches in diameter by 14 inches tall with at 
least the front portion clear. If the enclosure is also used for the 
saccharin solution aerosol fit test in compliance with section II(c)(2) 
of this appendix, the enclosure must allow free movements of the head 
when a respirator is worn. An enclosure substantially similar to the 
Minnesota, Mining and Manufacturing (3M) hood assembly, parts No. FT 14 
and No. FT 15 combined, is adequate.
    (ii) The test enclosure must have a \3/4\ inch hole in front of the 
test subject's nose and mouth area to accommodate the nebulizer nozzle.
    (iii) The test subject must don the test enclosure. Throughout the 
threshold screening test, the test subject must breathe with mouth wide 
open and tongue extended.
    (iv) Using a DeVilbiss Model 40 Inhalation Medication Nebulizer, the 
test conductor must spray the threshold check solution in accordance 
with II(c)(1)(v) of this appendix into the enclosure. The nebulizer must 
be clearly marked to distinguish it from the fit test solution 
nebulizer.
    (v) The threshold check solution consists of 0.83 grams of sodium 
saccharin USP in one cc of warm water. It may be prepared by putting one 
cc of the fit test solution (see section II(c)(2)(iv) of this appendix) 
in 100 cc of distilled water.
    (vi) To produce the aerosol, the nebulizer bulb must be firmly 
squeezed so that it collapses completely. Then, the bulb must be 
released and allowed to expand fully.
    (vii) The bulb must be squeezed rapidly ten times and the test 
subject must be asked whether he or she tastes the saccharin.
    (viii) If the first response is negative, the ten rapid squeezes 
must be repeated and the test subject is again asked whether he or she 
tastes the saccharin.
    (ix) If the second response is negative, ten more squeezes are 
repeated rapidly and the test subject again asked whether the saccharin 
is tasted.
    (x) The test conductor must take note of the number of squeezes 
required to solicit a taste response.
    (xi) If the saccharin is not tasted after 30 squeezes, the test 
subject may not perform the saccharin fit test.

[[Page 423]]

    (xii) If a taste response is elicited, the test subject must be 
asked to take note of the taste for reference in the fit test.
    (xiii) Correct use of the nebulizer means that approximately one cc 
of liquid is used at a time in the nebulizer body.
    (xiv) The nebulizer must be thoroughly rinsed in water, shaken dry, 
and refilled at least each morning and afternoon or at least every four-
hours.
    (2) Saccharin solution aerosol fit test. (i) The test subject may 
not eat, drink (except plain water), or chew gum for 15 minutes before 
the test.
    (ii) The fit test must be conducted with the same type of enclosure 
used for the saccharin taste threshold screening test in accordance with 
section II(c)(1) of this appendix.
    (iii) The test subject must don the enclosure while wearing the 
respirator selected in the saccharin taste threshold screening test. The 
respirator must be properly adjusted and equipped with a particulate 
filter(s).
    (iv) A second DeVilbiss Model 40 Inhalation Medication Nebulizer 
must be used to spray the fit test solution into the enclosure. This 
nebulizer must be clearly marked to distinguish it from the nebulizer 
used for the threshold check solution in accordance with section 
II(c)(1)(iv) of this appendix.
    (v) The fit test solution must be prepared by adding 83 grams of 
sodium saccharin to 100 cc of warm water.
    (vi) The test subject must breathe with mouth wide open and tongue 
extended.
    (vii) The nebulizer must be inserted into the hole in the front of 
the enclosure and the fit test solution must be sprayed into the 
enclosure using the same number of squeezes required to elicit a taste 
response in the screening test in accordance with sections II(c)(1)(vi) 
through II(c)(1)(xi) of this appendix.
    (viii) After generating the aerosol, the test subject must be 
instructed to perform the exercises in section I(n) of this appendix.
    (ix) Every 30 seconds, the aerosol concentration must be replenished 
using one half the number of squeezes used initially.
    (x) The test subject must indicate to the test conductor if, at any 
time during the fit test, the taste of saccharin is detected.
    (xi) If the taste of saccharin is detected, the fit must be deemed 
unsatisfactory and a different respirator must be tried.
    (d) Irritant fume test. The irritant fume test is an alternative 
qualitative fit test.
    (1) The respirator to be tested must be equipped with high-
efficiency particulate air (HEPA) filters.
    (2) The test subject must be allowed to smell a weak concentration 
of the irritant smoke before the respirator is donned to become familiar 
with the smoke's characteristic odor.
    (3) Both ends of a ventilation smoke tube containing stannic 
oxychloride, such as the Marine Safety Appliance part No. 5645 or 
equivalent, must be broken. One end of the smoke tube must be attached 
to a low flow air pump set to deliver 200 milliliters per minute.
    (4) The test subject must be advised that the smoke may be 
irritating to the eyes and that the subject must keep his or her eyes 
closed while the test is performed.
    (5) The test conductor must direct the stream of irritant smoke from 
the smoke tube towards the face seal area of the test subject. The test 
must be started with the smoke tube at least 12 inches from the 
facepiece, moved gradually to within one inch, and moved around the 
whole perimeter of the mask
    (6) Each test subject who passes the smoke test without evidence of 
a response must be given a sensitivity check of the smoke from the same 
tube once the respirator has been removed. This check is necessary to 
determine whether the test subject reacts to the smoke. Failure to evoke 
a response voids the fit test.
    (7) The fit test must be performed in a location with exhaust 
ventilation sufficient to prevent general contamination of the testing 
area by the irritant smoke.

                   III. Quantitative Fit Tests (ONFT)

    (a) General. (1) The employer shall designate specific individuals 
to administer the respirator quantitative fit test program.
    (2) The employer shall ensure that persons administering QNFT are 
able to properly calibrate equipment, perform tests, recognize invalid 
tests, calculate fit factors, and determine whether the test equipment 
is in proper working order.
    (3) The employer shall ensure that QNFT equipment is kept clean and 
maintained so as to operate at the parameters for which it was designed.
    (b) Definitions. (1) Quantitative fit test means a test which is 
performed in a test chamber and in which the normal air-purifying 
element of the respirator is replaced with a high-efficiency particulate 
air (HEPA) filter, in the case of particulate QNFT aerosols, or with a 
sorbent offering contaminant penetration protection equivalent to high-
efficiency filters, if the QNFT test agent is a gas or vapor.
    (2) Challenge agent means the aerosol, gas, or vapor introduced into 
a test chamber so that its concentration inside and outside of the 
respirator may be measured.
    (3) Test subject means the person wearing the respirator for 
quantitative fit testing.
    (4) Normal standing position means an erect and straight stance with 
arms down along the sides and eyes looking straight ahead.

[[Page 424]]

    (5) Maximum peak penetration method means the method of determining 
test agent penetration in the respirator as determined by strip chart 
recordings of the test. The highest peak penetration for a given 
exercise is taken to be representative of average penetration into the 
respirator for that exercise.
    (6) Average peak penetration method means the method of determining 
test agent penetration into the respirator by using a strip chart 
recorder, integrator, or computer. The agent penetration is determined 
by an average of the peak heights on the graph, or by computer 
integration, for each exercise except the grimace exercise. Integrators 
or computers which calculate the actual test agent penetration into the 
respirator for each exercise also may be used in accordance with this 
method.
    (7) Fit factor means the ratio of challenge agent concentration 
outside with respect to the inside of a respirator inlet covering 
(facepiece or enclosure).
    (c) Apparatus. (1) Instrumentation. Aerosol generation, dilution, 
and measurement systems using corn oil or sodium chloride as test 
aerosols must be used for quantitative fit testing.
    (2) Test chamber. The test chamber must be large enough to permit 
all test subjects to perform freely all required exercises without 
disturbing the challenge agent concentration or the measurement 
apparatus. The test chamber must be equipped and constructed so that the 
challenge agent is effectively isolated from the ambient air, yet is 
uniform in concentration throughout the chamber.
    (3) When testing air-purifying respirators, the normal filter or 
cartridge element must be replaced with a high-efficiency particulate 
filter supplied by the same manufacturer.
    (4) The sampling instrument must be selected so that a strip chart 
record may be made of the test showing the rise and fall of the 
challenge agent concentration with each inspiration and expiration at 
fit factors of at least 2,000. Integrators or computers which integrate 
the amount of test agent penetration leakage into the respirator for 
each exercise may be used if a record of the readings is made.
    (5) The combination of substitute air-purifying elements, challenge 
agent, and challenge agent concentration in the test chamber must be 
such that the test subject is not exposed to a concentration of the 
challenge agent in excess of the established exposure limit for the 
challenge agent at any time during the testing process.
    (6) The sampling port on the test specimen respirator must be placed 
and constructed so that no leakage occurs around the port (e.g. where 
the respirator is probed), so that a free air flow is allowed into the 
sampling line at all times, and so that there is no interference with 
the fit or performance of the respirator.
    (7) The test chamber and test set up must permit the person 
administering the test to observe the test subject inside the chamber 
during the test.
    (8) The equipment generating the challenge atmosphere must maintain 
a constant concentration of challenge agent inside the test chamber to 
within a ten percent variation for the duration of the test.
    (9) The time lag (i.e., the interval between an event and the 
recording of the event on the strip chart, computer, or integrator) must 
be kept to a minimum. There must be a clear association between the 
occurrence of an event inside the test chamber and the recording of that 
event.
    (10) The sampling line tubing for the test chamber atmosphere and 
for the respirator sampling port must be of equal diameter and of the 
same material. The length of the two lines must be equal.
    (11) The exhaust flow from the test chamber must pass through a 
high-efficiency filter before release.
    (12) When sodium chloride aerosol is used, the relative humidity 
inside the test chamber must not exceed 50 percent.
    (13) The limitations of instrument detection must be taken into 
account when determining the fit factor.
    (14) Test respirators must be maintained in proper working order and 
inspected for deficiencies, such as cracks, missing valves, and gaskets.
    (d) Procedural requirements. (1) When performing the initial 
positive or negative pressure test, the sampling line must be crimped 
closed in order to avoid air pressure leakage during either of these 
tests.
    (2) In order to reduce the amount of QNFT time, an abbreviated 
screening isoamyl acetate test or irritant fume test may be used in 
order to quickly identify poor fitting respirators which passed the 
positive or negative pressure test. When performing a screening isoamyl 
acetate test, combination high-efficiency organic vapor cartridges or 
canisters must be used.
    (3) A reasonably stable challenge agent concentration must be 
measured in the test chamber before testing. For canopy or shower 
curtain type of test units, the determination of the challenge agent 
stability may be established after the test subject has entered the test 
environment.
    (4) Immediately after the subject enters the test chamber, the 
challenge agent concentration inside the respirator must be measured to 
ensure that the peak penetration does not exceed five percent for a half 
mask or one percent for a full facepiece respirator.
    (5) A stable challenge concentration must be obtained before the 
actual start of testing.

[[Page 425]]

    (6) Respirator restraining straps must not be overtightened for 
testing. The straps must be adjusted by the wearer without assistance 
from other persons to give a fit reasonably comfortable for normal use.
    (7) After obtaining a stable challenge concentration, the test 
subject must be instructed to perform the exercises described in section 
I(n) of this appendix. The test must be terminated whenever any single 
peak penetration exceeds five percent for half masks and one percent for 
full facepiece respirators. The test subject must be refitted and 
retested. If two of the three required tests are terminated, the fit is 
deemed inadequate.
    (8) In order to successfully complete a QNFT, three successful fit 
tests must be conducted. The results of each of the three independent 
fit tests must exceed the minimum fit factor needed for the class of 
respirator (e.g., half mask respirator, full facepiece respirator).
    (9) Calculation of fit factors. (i) The fit factor must be 
determined for the quantitative fit test by taking the ratio of the 
average chamber concentration to the concentration inside the 
respirator.
    (ii) The average test chamber concentration is the arithmetic 
average of the test chamber concentration at the beginning and of the 
end of the test.
    (iii) The concentration of the challenge agent inside the respirator 
must be determined by one of the following methods:
    (A) Average peak concentration.
    (B) Maximum peak concentration.
    (C) Integration by calculation of the area under the individual peak 
for each exercise. This includes computerized integration.
    (10) Interpretation of test results. The fit factor established by 
the quantitative fit testing must be the lowest of the three fit factor 
values calculated from the three required fit tests.
    (11) The test subject must not be permitted to wear a half mask or a 
full facepiece respirator unless a minimum fit factor equivalent to at 
least ten times the hazardous exposure level is obtained.
    (12) Filters used for quantitative fit testing must be replaced at 
least weekly, whenever increased breathing resistance is encountered, or 
whenever the test agent has altered the integrity of the filter media. 
When used, organic vapor cartridges and canisters must be replaced daily 
or whenever there is an indication of a breakthrough by a test agent.

        Sec. Appendix A to Part 197--Air No-Decompression Limits

    The following table gives the depth versus bottom time limits for 
single, no-decompression, air dives made within any 12-hour period. The 
limit is the maximum bottom time in minutes that a diver can spend at 
that depth without requiring decompression beyond that provided by a 
normal ascent rate of 60 fsw per minute. (Although bottom time is 
concluded when ascent begins, a slower ascent rate would increase the 
bottom time thereby requiring decompression.) An amount of nitrogen 
remains in the tissues of a diver after any air dive, regardless of 
whether the dive was a decompression or no-decompression dive. Whenever 
another dive is made within a 12-hour period, the nitrogen remaining in 
the blood and body tissues of the diver must be considered when 
calculating his decompression.

requirements of this part unreasonable or unnecessary and which in the 
course of the voyage does not proceed more than 20 miles from the 
nearest land.
    (ii) A vessel embodying features of a novel kind to which the 
application of any provision of this part would seriously impede 
research into the development of such features and their incorporation 
on vessels engaged on international voyages.
    (2) A written request for exemption under this section must be 
submitted to the cognizant OCMI for review and forwarding to Commandant 
(CG-CVC).
    (b) Single voyage exemption from SOLAS requirements. A vessel that 
is not normally engaged on international voyages, but which, under 
exceptional circumstances, is required to undertake a single 
international voyage, may be exempted from the applicable requirements 
in this subpart and subparts B, C, and D of this part by the Commandant 
(CG-CVC). A written request for exemption under this paragraph must be 
submitted to the cognizant OCMI for review and forwarding to Commandant 
(CG-CVC).
    (c) Exemption Certificates. When Commandant (CG-CVC) grants an 
exemption under paragraph (a) or (b) of this section, an Exemption 
Certificate describing the exemption will be issued by the appropriate 
OCMI. The Exemption Certificate must be carried on board the vessel at 
all times and must be available to Coast Guard personnel upon request.
    (d) Vessels not engaged on international voyages. (1) If a District 
Commander determines that the overall safety of the persons on board a 
vessel will not be significantly reduced, the District Commander may 
grant an exemption from compliance with a provision of this part to a 
specific vessel for a specified geographic area within the boundaries of 
the Coast Guard District. This exemption may be limited to certain 
periods of the year.
    (2) Requests for exemption under this paragraph must be made in 
writing to the OCMI for transmission to the District Commander for the 
area in which the vessel is in service or will be in service.
    (3) If the exemption is granted by the District Commander, the OCMI 
will endorse the vessel's Certificate of Inspection with a statement 
describing the exemption.

    (b) Familiarity with emergency procedures. (1) Every crewmember with 
emergency duties assigned on the muster list must be familiar with their 
assigned duties before the voyage begins.
    (2) On a vessel engaged on voyage when the passengers or special 
personnel are scheduled to be on board for more than 24 hours, musters 
of the passengers and special personnel must take place within 24 hours 
after their embarkation. Passengers and special personnel must be 
instructed in the use of the lifejackets and the action to take in an 
emergency.
    (3) Whenever new passengers or special personnel embark, a safety 
briefing must be given immediately before sailing or immediately after 
sailing. The briefing must include the instructions required by Sec.  
199.80 and must be made by means of an announcement in one or more 
languages likely to be understood by the passengers and special 
personnel. The announcement must be made on the vessel's public address 
system or by other equivalent means likely to be heard by the passengers 
and special personnel who have not yet heard it during the voyage. The 
briefing may be included in the muster required by paragraph (b)(2) of 
this section if the muster is held immediately upon departure. 
Information cards or posters, or video programs displayed on the vessel 
video displays, may be used to supplement the briefing, but may not be 
used to replace the announcement.
    (c) Drills--general. (1) Drills must, as far as practicable, be 
conducted as if there were an actual emergency.
    (2) Every crewmember must participate in at least one abandon-ship 
drill and one fire drill every month. The drills of the crew must take 
place within 24 hours of the vessel leaving a port if more than 25 
percent of the crew have not participated in abandon-ship and fire 
drills on board that particular vessel in the previous month.
    (3) Drills must be held before sailing when a vessel enters service 
for the first time, after modification of a major character, or when a 
new crew is engaged.

section, each lifeboat must be launched with its assigned operating crew 
aboard and maneuvered in the water at least once every 3 months during 
an abandon-ship drill.
    (5) Lowering into the water, rather than launching of a lifeboat 
arranged for free-fall launching, is acceptable when free-fall launching 
is impracticable, provided that the lifeboat is free-fall launched with 
its assigned operating crew aboard and is maneuvered in the water at 
least once every 6 months. However, when compliance with the 6-month 
requirement is impracticable, the OCMI may extend this period to 12 
months, provided that arrangements are made for simulated launching at 
intervals of not more than 6 months.
    (6) The OCMI may exempt a vessel operating on short international 
voyages from the requirement to launch the lifeboats on both sides of 
the vessel if berthing arrangements in port and operations do not permit 
launching of lifeboats on one side. However, all lifeboats on the vessel 
must be lowered at least once every 3 months and launched at least 
annually.
    (7) As far as is reasonable and practicable, rescue boats, other 
than lifeboats which are also rescue boats, must be launched with their 
assigned crew aboard and maneuvered in the water each month. Such 
launching and maneuvering must occur at least once every 3 months.
    (8) If lifeboat and rescue boat launching drills are carried out 
with the vessel making headway, such drills must, because of the dangers 
involved, be practiced in sheltered waters only and be under the 
supervision of an officer experienced in such drills.
    (9) If a vessel is fitted with marine evacuation systems, drills 
must include an exercising of the procedures required for the deployment 
of such a system up to the point immediately preceding actual deployment 
of the system. This aspect of drills should be augmented by regular 
instruction using the on board training aids. Additionally, every 
crewmember assigned to duties involving the marine evacuation system 
must, as far as practicable, participate in a full deployment of a 
similar system into water, either on board a vessel or ashore, every 2 
years but not longer than every 3 years. This training may be associated 
with the deployments required by Sec.  199.190(k).
    (10) Emergency lighting for mustering and abandonment must be tested 
at each abandon-ship drill.
    (11) If a vessel carries immersion suits or anti-exposure suits, the 
suits must be worn by crewmembers in at least one abandon ship drill in 
any three-month period. If wearing the suits is impracticable due to 
warm weather, the crewmembers must be instructed on their donning and 
use.
    (12) If a vessel carries immersion suits for persons other than the 
crew, the abandon-ship drill must include instruction to these persons 
on the stowage, donning, and use of the suits.
    (e) Line-throwing appliance. A drill must be conducted on the use of 
the line-throwing appliance at least once every 3 months. The actual 
firing of the appliance is at the discretion of the master.
    (f) Fire drills. (1) Fire drills must, as far as practicable, be 
planned with due consideration given to the various emergencies that may 
occur for that type of vessel and its cargo.
    (2) Each fire drill must include--
    (i) Reporting to stations and preparing for the duties described in 
the muster list for the particular fire emergency being simulated;
    (ii) Starting of fire pumps and the use of two jets of water to 
determine

[[Page 457]]

that the system is in proper working order;
    (iii) Checking the firemen's outfits and other personal rescue 
equipment;
    (iv) Checking the relevant communications equipment;
    (v) Checking the operation of watertight doors, fire doors, and fire 
dampers and main inlets and outlets of ventilation systems in the drill 
area; and
    (vi) Checking the necessary arrangements for subsequent abandonment 
of the vessel.
    (3) The equipment used during drills must immediately be brought 
back to its fully operational condition. Any faults and defects 
discovered during the drills must be remedied as soon as possible.
    (g) Onboard training and instruction. (1) Onboard training in the 
use of the vessel's lifesaving appliances, including survival craft 
equipment, and in the use of the vessel's fire-extinguishing appliances 
must be given as soon as possible but not later than 2 weeks after a 
crewmember joins the vessel.
    (2) If the crewmember is on a regularly scheduled rotating 
assignment to the vessel, the training required in paragraph (g)(1) of 
this section need be given only within 2 weeks of the time the 
crewmember first joins the vessel.
    (3) The crew must be instructed in the use of the vessel's fire-
extinguishing and lifesaving appliances and in survival at sea at the 
same interval as the drills. Individual units of instruction may cover 
different parts of the vessel's lifesaving and fire-extinguishing 
appliances, but all the vessel's lifesaving and fire-extinguishing 
appliances must be covered within any period of 2 months.
    (4) Every crewmember must be given instructions that include, but 
are not limited to--
    (i) The operation and use of the vessel's inflatable liferafts;
    (ii) The problems of hypothermia, first aid treatment for 
hypothermia, and other appropriate first aid procedures;
    (iii) Any special instructions necessary for use of the vessel's 
lifesaving appliances in severe weather and severe sea conditions; and
    (iv) The operation and use of fire-extinguishing appliances.
    (5) Onboard training in the use of davit-launched liferafts must 
take place at intervals of not more than 4 months on each vessel with 
davit-launched liferafts. Whenever practicable, this training must 
include the inflation and lowering of a liferaft. If this liferaft is a 
special liferaft intended for training purposes only and is not part of 
the vessel's lifesaving equipment, this liferaft must be conspicuously 
marked.
    (h) Records. (1) When musters are held, details of abandon-ship 
drills, fire drills, drills of other lifesaving appliances, and onboard 
training must be recorded in the vessel's official logbook. Logbook 
entries must include--
    (i) The date and time of the drill, muster, or training session;
    (ii) The survival craft and fire-extinguishing equipment used in the 
drills;

\1\ Alternative applies if lifebuoy is orange.
\2\ Alternative applies only to cargo vessels that are less than 500 tons gross tonnage.
\3\ Alternative applies to cargo vessels that are less than 500 tons gross tonnage and to all passenger vessels.
\4\ Alternative applies to passenger vessels limited to operating no more than 50 nautical miles from shore.

    (b) Lifebuoy approval series. As an alternative to a lifebuoy 
approved under approval series 160.150, vessels may carry a lifebuoy 
approved under approval series 160.050.
    (c) Lifejackets approval series. As an alternative to a lifejacket 
meeting the approval requirements in Sec.  199.70, vessels may carry a 
lifejacket approved under approval series 160.002, 160.005, 160.055, or 
160.077.
    (d) Lifejacket quantity. Vessels may carry lifejackets as follows:
    (1) If lifejackets are stowed in cabins, staterooms, or berthing 
areas that are readily accessible to each watch or

[[Page 468]]

work station, the requirement in Sec.  199.70(b)(2)(iv) to have 
lifejackets at each watch or work station need not be met.
    (2) If the vessel carries lifejackets that are designated extended-
size, then the number of child-size lifejackets carried to meet Sec.  
199.70(b)(1)(i) may be reduced. To take the reduction in child-size 
lifejackets, extended-size lifejackets having the same lower size limit 
must be substituted for all of the required adult lifejackets. The 
number of child-size lifejackets required depends on the lower size 
limit of the extended-size lifejackets and is calculated by any one of 
the following formulas where PC is the number of child-size lifejackets 
expressed as a percentage of the number of lifejackets required under 
Sec.  199.70(b)(1):
    (i) PC = LS / 4.1, where LS equals the lower size limit expressed in 
kilograms.
    (ii) PC = LS / 9, where LS equals the lower size limit expressed in 
pounds.
    (iii) PC = (LS-81) / 7.6, where LS equals the lower size limit 
expressed in centimeters.
    (iv) PC = (LS-32) / 3, where LS equals the lower size limit 
expressed in inches.
    (e) Lifejacket light approval series. As an alternative to lights 
approved under approval series 161.112, vessels may use lights for 
lifejackets and immersions suits approved under series 161.012. However, 
lifejacket lights bearing Coast Guard approval number 161.012/2/1 are 
not permitted on vessels certificated to operate on waters where water 
temperature may drop below 10 [deg]C (50 [deg]F).
    (f) Embarkation ladder. An embarkation ladder may be a chain ladder 
approved under approval series 160.017.
    (g) Survival craft stowage positions. Vessels having widely 
separated accommodation and service spaces may have, as an alternative 
to the requirements of Sec.  199.130(b), all required lifeboats and 50 
percent of the required liferafts stowed as close as possible to the 
accommodation and service space that normally holds the greatest number 
of persons, with the remainder of the liferafts stowed as close as 
possible to each other accommodation and service space.
    (h) Line-throwing appliance approval series. As an alternative to a 
line-throwing appliance that meets the requirements in Sec.  199.170, 
vessels may carry a line-throwing appliance approved under approval 
series 160.031, which may have an auxiliary line that is at least 150 
meters (500 feet).
    (i) Lifeboat, rescue boat, and rigid liferaft equipment; oceans and 
coastwise. Lifeboats, rescue boats, and rigid liferafts may carry the 
equipment specified in table 199.175 of this part for vessels on a short 
international voyage.
    (j) Lifeboat, rescue boat, and rigid liferaft equipment; other 
services. As an alternative to meeting the survival craft equipment 
requirements of Sec.  199.175, a vessel may carry the equipment 
specified in table 199.620(j) of this section under the vessel's 
category of service. Each item in the table has the same description as 
in Sec.  199.175.

sufficient to accommodate not less than 30 percent of the total number 
of persons on board. These lifeboats must be equally distributed, as far 
as practicable, on each side of the vessel. Liferafts on these vessels 
may be either SOLAS A or SOLAS B liferafts.
    (d) As an alternative to the survival craft requirements of Sec.  
199.201(b), vessels may carry inflatable buoyant apparatus having an 
aggregate capacity, together with the capacities of any lifeboats, 
rescue boats, and liferafts carried on board sufficient to, accommodate 
the total number of persons on board. These inflatable buoyant apparatus 
must--
    (1) Be served by launching appliances or marine evacuation systems 
evenly distributed on each side of the vessel if the embarkation deck is 
more than 3 meters (10 feet) above--
    (i) The waterline under normal operating conditions; or
    (ii) The equilibrium waterline after the vessel is subjected to the 
assumed damage and subdivision requirements in part 171 of this chapter;
    (2) Be stowed in accordance with the requirements of Sec. Sec.  
199.130(a), 199.130(c), and 199.178; and
    (3) Be equipped in accordance with the requirements in table 
199.640(j) of this part.
    (e) As an alternative to the survival craft requirements of Sec.  
199.201(b), vessels may carry--
    (1) Liferafts having an aggregate capacity, together with the 
capacities of any lifeboats carried on board, sufficient to accommodate 
the total number of persons on board that are served by launching 
appliances or marine evacuation systems evenly distributed on each side 
of the vessel; and
    (2) In addition to the liferafts required in paragraph (e)(1) of 
this section, additional liferafts that have an aggregate capacity 
sufficient to accommodate at least 10 percent of the total number of 
persons, or equal to the capacity of the largest single survival craft 
on the vessel, whichever is the greater. The additional liferafts are 
not required to be stowed in accordance with Sec.  199.130(c), but they 
must be served by at least one launching appliance or marine evacuation 
system on each side of the vessel.

[[Page 471]]

    (f) As an alternative to the survival craft requirements of Sec.  
199.201(b), vessels may have a safety assessment approved by the local 
OCMI that addresses the following:
    (1) The navigation and vessel safety conditions within the vessel's 
planned operating area including--
    (i) The scope and degree of the risks or hazards to which the vessel 
will be subject during normal operations;
    (ii) The existing vessel traffic characteristics and trends, 
including traffic volume; the sizes and types of vessels involved; 
potential interference with the flow of commercial traffic; the presence 
of any unusual cargoes; and other similar factors;
    (iii) The port and waterway configuration and variations in local 
conditions of geography, climate, and other similar factors; and
    (iv) Environmental factors.
    (2) A comprehensive shipboard safety management and contingency plan 
that is tailored to the particular vessel, is easy to use, is understood 
by vessel management personnel both on board and ashore, is updated 
regularly, and includes--
    (i) Guidance to assist the vessel's crew in meeting the demand of 
catastrophic vessel damage;
    (ii) Procedures to mobilize emergency response teams;
    (iii) Procedures for moving passengers from the vessel's spaces to 
areas protected from fire and smoke, to embarkation areas, and off the 
vessel. The procedures must address provisions for passengers with 
physical or mental impairments;
    (iv) Lists of external organizations that the vessel's operator 
would call for assistance in the event of an incident;
    (v) Procedures for establishing and maintaining communications on 
board the vessel and with shoreside contacts; and
    (vi) Guidance on theoretical, practical, and actual simulation 
training that includes the personnel or organizations identified in the 
plan so they can practice their roles in the event of an incident.
    (g) As an alternative to the survival craft requirements of Sec.  
199.201(b), vessels may carry inflatable buoyant apparatus having an 
aggregate capacity sufficient to accommodate 67 percent of the total 
number of persons on board, minus the capacities of any lifeboats, 
rescue boats and liferafts carried on board. These inflatable buoyant 
apparatus must meet the arrangement requirements of Sec.  199.630 (d)(1) 
through (d)(3). The number of persons accommodated in an inflatable 
buoyant apparatus may not exceed 150% of its rated capacity.
    (h) A vessel need not comply with the requirements for survival 
craft in Sec.  199.201(b) if the vessel operates--
    (1) On a route that is in shallow water not more than 3 miles from 
shore and the vessel cannot sink deep enough to submerge the topmost 
deck; or
    (2) Where the cognizant OCMI determines that survivors can wade 
ashore.
    (i) As an alternative to the rescue boat required in Sec.  199.202, 
vessels may carry a rescue boat meeting the requirements of part 160, 
subpart 160.056 of this chapter if it is equipped with a motor and meets 
the following:
    (1) The towline for the rescue boat must be at least the same size 
and length as the rescue boat painter.
    (2) The rescue boat must meet the embarkation, launching, and 
recovery arrangement requirements in Sec.  199.160 (b) through (f). The 
OCMI may allow deviations from the rescue boat launching requirements 
based on the characteristics of the boat and the conditions of the 
vessel's route.
    (j) As an alternative to the requirements of Sec.  199.203(a), a 
vessel that meets the subdivision requirements in Sec.  171.068 of this 
chapter may meet the requirements of Sec.  199.203(b).
    (k) Vessels carrying lifebuoys may carry--
    (1) The number of lifebuoys specified in table 199.630(k) of this 
section instead of the number required in Sec.  199.211; and
    (2) If the vessel carries less than four lifebuoys, at least two 
with a self-igniting light attached to the lifebuoy. A buoyant lifeline 
may be fitted to one of the lifebuoys with a self-igniting light.

    (l) A deck officer, able seaman, certificated person, or person 
practiced in the handling of liferafts or inflatable buoyant apparatus 
is not required to be placed in charge of each inflatable buoyant 
apparatus, provided that there are a sufficient number of such persons 
on board to launch the inflatable buoyant apparatus and supervise the 
embarkation of the passengers. The number of persons on board for the 
purpose of launching and operating inflatable buoyant apparatus may be 
reduced during any voyage where the vessel is carrying less than the 
number of passengers permitted on board, and the number of such persons 
is sufficient to launch and operate the number of survival craft 
required to accommodate everyone on board.
    (m) The person designated second-in-command of survival craft is not 
required to be a certificated person if the person is practiced in the 
handling and operation of survival craft.

Notes:
\1\ Alternative applies to vessels less than 150 tons gross tonnage that do not carry passengers or persons in
  addition to the crew.
\2\ Alternative applies to cargo vessels less than 85 meters in length, tank vessels less than 500 tons gross
  tonnage, and nonself-propelled vessels.
\3\ Alternative applies during periods of the year that the vessel operates in warm water.
\4\ Alternative applies if the vessel operates in shallow water not more than 3 miles from shore where the
  vessel cannot sink deep enough to submerge the topmost deck.
\5\ Alternative applies if the vessel operates on sheltered lakes or harbors.
\6\ Alternative applies to vessels less than 500 tons gross tonnage.

    (b) Vessels of less than 150 tons gross tonnage that do not carry 
persons other than the crew, may carry, as an alternative to distress 
signals that meet the requirements of Sec.  199.60, six hand red flare 
distress signals approved under approval series 160.021 and six hand 
orange smoke distress signals approved under approval series 160.037.
    (c) As an alternative to the survival craft requirements of Sec.  
199.261(b), (c), or (d), vessels may carry one or more liferafts with an 
aggregate capacity sufficient to accommodate the total number of persons 
on board. The liferafts must be--
    (1) Readily transferable for launching on either side of the vessel; 
or

[[Page 473]]

    (2) Supplemented with additional liferafts to bring the total 
capacity of the liferafts available on each side of the vessel to at 
least 100 percent of the total number of persons on board. If additional 
liferafts are provided and the rescue boat required under Sec.  199.262 
is also a lifeboat, its capacity may be included in meeting the 
aggregate capacity requirement.
    (d) As an alternative to the survival craft requirements in Sec.  
199.261 (b), (c), or (d), vessels may carry one or more totally enclosed 
lifeboats with an aggregate capacity sufficient to accommodate the total 
number of persons on board and one or more liferafts with an aggregate 
capacity sufficient to accommodate the total number of persons on board. 
This combination of survival craft must meet the following:
    (1) The aggregate capacity of the lifeboats and liferafts on each 
side of the vessel must be sufficient to accommodate the total number of 
persons on board.
    (2) If the survival craft are stowed more than 100 meters (328 feet 
from either the stem or the stern of the vessel, an additional liferaft 
must be carried and stowed as far forward or aft as is reasonable and 
practicable. The requirement for the liferaft to float free under Sec.  
199.290(b) does not apply to a liferaft under this paragraph, provided 
the liferaft is arranged for quick manual release.
    (e) As an alternative to the survival craft requirements in Sec.  
199.261 (b), (c), or (d), during periods of the year the vessel operates 
in warm water, a vessel may carry lifefloats with an aggregate capacity 
sufficient to accommodate the total number of people on board. The 
lifefloat launching arrangement, stowage, and equipment must meet the 
requirements in Sec.  199.640(j).
    (f) A vessel need not comply with the requirements for survival 
craft in Sec.  199.261 (b), (c), or (d) if the vessel operates--
    (1) On a route that is in shallow water not more than 3 miles from 
shore and where the vessel cannot sink deep enough to submerge the 
topmost deck; or
    (2) Where the cognizant OCMI determines that survivors can wade 
ashore.
    (g) As an alternative to the rescue boat requirement in Sec.  
199.262(a), vessels may carry a motor-propelled workboat or a launch 
that meets all the embarkation, launching, and recovery arrangement 
requirements in Sec.  199.160 (b) through (f). The OCMI may allow 
deviations from the rescue boat launching requirements based on the 
characteristics of the boat and the conditions of the vessel's route.
    (h) As an alternative to the rescue boat requirement in Sec.  
199.262, vessels may carry a rescue boat meeting the requirements of 
part 160, subpart 160.056 of this chapter if the rescue boat is equipped 
with a motor and meets the following:
    (1) The towline for the rescue boat must be at least the same size 
and length as the rescue boat painter.
    (2) The rescue boat must meet the embarkation, launching, and 
recovery arrangement requirements in Sec.  199.160(b). A manually-
powered winch may be used if personnel embark and disembark the rescue 
boat only when it is in the water. If the rescue boat is launched or 
recovered with personnel on board, the embarkation, launching, and 
recovery arrangements must also meet Sec.  199.160 (c) through (f). The 
OCMI may allow deviations from the rescue boat launching requirements 
based on the characteristics of the boat and the conditions of the 
vessel's route.
    (i) As an alternative to the number of lifebuoys required in Sec.  
199.271, vessels may carry--
    (1) If the vessel is self-propelled, the number of lifebuoys 
specified in table 199.640(i) of this section; or
    (2) If the vessel is non self-propelled, one lifebuoy on each end of 
the vessel.
