To cite the regulations in this volume use title, part and section number. Thus, 46 CFR 166.01 refers to title 46, part 166, section 01.

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, 2017), 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. 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 accidentally dropped due to a printing or computer 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.
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
§ 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]
§ 167.01-5
Applicability; preemptive effect.
(a) Regulations in this part contain requirements for the design, construction, inspection, lifesaving equipment, 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.
[CGFR 51-11, 16 FR 3218, Apr. 12, 1951, as amended by CGFR 69-127, 35 FR 9982, June 17, 1970; CGD 90-008, 55 FR 30663, July 26, 1990; USCG-2006-24797, 77 FR 33888, June 7, 2012; USCG-2012-0196, 81 FR 48294, July 22, 2016]

[CGFR 59-10, 24 FR 3240, Apr. 25, 1959]
§ 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 § 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]
§ 167.01-10
Effective date of regulations.

(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, 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 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 (CO 2 ) 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:
where:
W = the weight of CO 2 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 (CO 2 ) 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 tightly lined with metal. The whole charge of gas shall be capable of being released simultaneously by operating one valve and control, and all cylinders shall be completely discharged in not more than two minutes.
(3) Pipes used for supplying carbon dioxide to the cargo holds, cargo 'tween-decks, other closed cargo compartments, and cargo-oil deep tanks shall be not less than three-fourths inch inside diameter. Pipes used for supplying carbon dioxide to lamp lockers, oil rooms, and like compartments shall not be less than one-half inch inside diameter.
(4) The control(s) releasing the inert gas shall be located in a position(s) outside the space(s) protected and shall be readily accessible when the vessel is being navigated. All valves shall be permanently marked to indicate into which compartment they discharge. A space which is protected by a carbon dioxide extinguishing system, and is normally accessible to crew while the nautical school ship is being navigated shall be fitted with an approved audible alarm in such space, which will be automatically sounded when the carbon dioxide is admitted to the space.
(5) Provisions shall be made to prevent the admission of air into the lower parts of cargo holds, cargo 'tween-decks, and other closed cargo compartments while the inert-gas system is in operation.
(6) Cylinders, piping, and controls for the inert-gas system shall be protected from damage and shall be securely fastened and supported.

§ 170.090
Calculations.
(a) All calculations required by this subchapter must be submitted with the plans required by § 170.075 of this subpart. Calculations must account for the weight of all loads carried aboard the vessel.
(b) If it is necessary to compute and plot any of the following curves as part of the calculations required in this subchapter, these plots must also be submitted:
(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 procedures at any time to amend this subchapter, including updates of the AAWPP.
(6) Updates to the AAWPP used in calculations showing compliance with this subchapter will be published in a separate Federal Register notice and other appropriate media, except when the Coast Guard conducts further rulemaking procedures under paragraph (d)(5) of this section.
(7) Notwithstanding any other provisions of this section, the Coast Guard may choose, in its discretion, to delay or dispense with any update of the AAWPP. In the event the Coast Guard elects to dispense with or delay an update that would otherwise issue as an interpretive rule pursuant to the provisions of this section, the Coast Guard will inform the public of the decision and explain the reasons in a Federal Register notice.
(e) To obtain an AAWPP update, add the mean weight of all U.S. males aged 20 years and older to the mean weight of all U.S. females aged 20 years and older, and divide the sum by 2. To this average of the mean weights, add 7.5 pounds of assumed clothing weight, and round the resulting sum to the nearest whole number in pounds.
(f) Updates to the AAWPP will become effective beginning one calendar year after publication in the Federal Register of a notice described in paragraphs (d)(3) and (d)(6) of this section, except the initial AAWPP issued pursuant to paragraph (d)(1) of this section will become effective on December 1, 2011. Notwithstanding any other provisions of this title, the Coast Guard may implement updates to the AAWPP at any time with less than one year of public notice when required for public safety reasons.
(g) The most recent Federal Register notice that publishes the AAWPP as determined by this section is also on file at the Coast Guard Headquarters.

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.
P = .0025 + (L/14,200) ^2 tons/ft ^2 . . . for service on protected 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 set and trimmed flat.
(d) The criterion specified in this section is generally limited in application to the conditions of loading and operation of flush deck, mechanically powered vessels of ordinary proportions and form for which the righting arm (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 § 170.173 are applied.

§ 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 § 171.065(a), (b), and (c):
(1) When doing calculations required to demonstrate compliance with § 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 § 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.

(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 § 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 § 171.065.
§ 171.068
Special considerations for Type I subdivision for vessels on short international voyages.
(a) The calculations done to demonstrate compliance with § 171.065 for a vessel that makes short international voyages and is permitted under § 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.
(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—

(A) The weight of each passenger is the weight used for calculations as determined in accordance with § 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.

(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.

[CGD 90-051, 57 FR 36246, Aug. 12, 1992]
§ 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 vessel is not carrying oil, other than oily residues, in cargo tanks.

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—
(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.

(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—

(2) Assumed in the design calculations required by § 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.

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 § 174.055(b)(3).
§ 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=Σ 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.
(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.

§ 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 §§ 174.075 through 174.085; and

§ 174.070
General damage stability assumptions.
For the purpose of determining compliance with § 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 §§ 174.075 through 174.085.
§ 174.075
Compartments assumed flooded: general.
The individual flooding of each of the compartments described in §§ 174.080 and 174.085 must be assumed for the purpose of determining compliance with § 174.065 (a). Simultaneous flooding of more than one compartment must be assumed only when indicated in §§ 174.080 and 174.085.
§ 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.

(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) 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
(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 §§ 174.075 through 174.085; and
(2) A wind heeling moment calculated in accordance with § 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—

(2) Have controls in accordance with ASTM F 1197 (incorporated by reference, see § 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 § 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 § 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 § 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.

(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. 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.

§ 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.

[USCG-1999-4976, 65 FR 6508, Feb. 9, 2000]
§ 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. 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]
§ 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 § 176.113 of this part.
[USCG-2007-0030, 75 FR 78087, Dec. 14, 2010]
§ 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;
(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 § 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 § 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]
§ 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;

Subpart F—Hull and Tailshaft Examinations
§ 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 § 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 § 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 § 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.

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

§ 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 § 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.

§ 178.450
Calculation of drainage area for cockpit and well deck vessels.
(a) The drainage area required on a vessel must be computed using the following formula:
For protected waters required drainage = .1 × Basic Drainage
For partially protected waters required drainage = .5 × Basis Drainage
For exposed waters required drainage = Basic Drainage
where:
Basic Drainage area in centimeters ^2 = 4389.12 × [(Recess Volume × Recess Ratio) + (Weather Deck Volume × Weather Deck Ratio)]; or
Basic Drainage area in inch ^2 = (Recess Volume × Recess Ratio) + (Weather Deck Volume × Weather Deck Ratio)
Recess Volume = (B R × D R ) − V R
B R = average height in centimeters (feet) of the bulwark above the well deck or cockpit deck;
D R = total deck area of the cockpit or well deck in the after 2/3 of the vessel length (LOD) measured in centimeters ^2 (feet ^2 ).
V R = volume of any weather tight structure below the bulwark of the well deck or cockpit deck.
Recess Ratio = L R / L C
L R = the length of the recess in the after 2/3 vessel length (LOD).
L C = 2/3 vessel length (LOD).
Weather Deck Volume = (B D × D D ) − V S
B D = average height in centimeters (feet) of the bulwark above the weather deck;
D D = total deck area of the weather deck adjacent to bulwarks but not in way of the cockpit or well deck in the after 2/3 of the vessel length (LOD) measured in centimenters ^2 (feet ^2 ).
V S = volume of any weather tight superstructure below the bulwark on the weather deck located within D D .
Weather Deck Ratio = L D / L C
L D = the length of the weather deck bulwark in the after 2/3 of the vessel length (LOD).
L C = 2/3 vessel length (LOD).
(b) Vessels with bulwarks in the forward part of the vessel shall not form a well with the deckhouse which retains water.

(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 applicable sections of UL 1058 (incorporated by reference, see 46 CFR 175.600) and the requirements of this paragraph (g).

§ 189.33-1
When made.
(a) An inspection of quarters, toilet and washing spaces, serving pantries, galleys, etc., shall be made at least once in every month. If the route of the vessel is such that it is away from a U.S. port for more than 1 month, an inspection shall be conducted at least once every trip.

Subpart 189.35—Weight Handling Gear
§ 189.35-1
Application.
(a) The requirements of this subpart shall apply to all weight handling gear installed on oceanographic research vessels except weight handling gear designated to handle primary lifesaving equipment. Weight 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.
§ 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.
§ 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.
§ 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.
§ 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.
(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 § 31.10-6.
(3) Hydraulic or pneumatic systems will be evaluated on the basis of Subchapter F (Marine Engineering) of this chapter.

Table 193.10-5( a )—Required Fire Pump System
Gross tons | Over | Not over | Minimum number of pumps | Hose and hydrant size, inches | Nozzle orifice size, inches | Length of hose, feet
| 100 | ^1 1 | ^1 1 1/2 | ^1 1/2 | 50
100 | 1,000 | 1 | 1 1/2 | 5/8 | 50
1,000 | 1,500 | 2 | 1 1/2 | 5/8 | 50
1,500 | | 2 | ^2 2 1/2 | ^2 7/8 | ^2 50
^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 § 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 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 § 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 § 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.

§ 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 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 § 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 § 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 § 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 or metal with strength and corrosion resistance equivalent to bronze. Combination solid stream and water spray nozzles previously approved under subpart 162.027 of this chapter may be retained so long as they are maintained in good condition to the satisfaction of the Officer in Charge, Marine Inspection.
(j) When the firehose nozzle in the below locations was previously approved under subpart 162.027 of this chapter, a low-velocity water spray applicator, also previously approved under subpart 162.027, of this chapter must be installed as follows:

(b) Installations contracted for prior to March 1, 1968, shall meet the requirements of § 193.15-90.
(c) The requirements of this subpart are based on a “high pressure system,” 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.
§ 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.

[CGD 88-040, 56 FR 52135, Oct. 17, 1991; 56 FR 65006, Dec. 13, 1991]
§ 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 (C 6 H 6 ; 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 § 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 § 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 § 197.550 and the personal protective clothing and equipment in compliance with § 197.555.
Regulated area means an area designated in compliance with § 197.535.
Short-term exposure limit or STEL means an airborne concentration of five parts of benzene per million parts of air (five ppm), as averaged over any 15 minute period.
Time-weighted average exposure limit or TWA means an airborne 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.

[CGD 88-040, 56 FR 52135, Oct. 17, 1991, as amended by CGD 95-072, 60 FR 50469, Sept. 29, 1995; CGD 96-041, 61 FR 50735, Sept. 27, 1996; 61 FR 52497, Oct. 7, 1996; 69 FR 18803, Apr. 9, 2004; USCG-2009-0702, 74 FR 49241, Sept. 25, 2009; USCG-2012-0832, 77 FR 59789, Oct. 1, 2012; USCG-2013-0671, 78 FR 60165, Sept. 30, 2013]
§ 197.515
Permissible exposure limits (PELs).
The permissible exposure limits (PELs) for personal exposure are as follows:
(a) The time-weighted average exposure limit (TWA).
(b) The short-term exposure limit (STEL). Exposures at the STEL must not be repeated more than four times a day. There must be at least 60 minutes between successive exposures at the STEL.
§ 197.520
Performance standard.
No person may be subjected to a personal exposure in excess of the permissible exposure limits unless respiratory protection is used.
§ 197.525
Responsibility of the person in charge.
Unless otherwise specified, the person in charge shall ensure that the performance standard and other requirements of this subpart are complied with on that person's vessel.
§ 197.530
Persons other than employees.
(a) Before a nonemployee (other than Federal, state, and local government personnel) engages in a benzene operation on a vessel in which the person is likely to be exposed to benzene in excess of the PELs, that person must certify that—
(1) That person has had, within the previous 12 months, at least one medical examination in compliance with § 197.560 or 29 CFR 1910.1028;
(2) The physician who performed or who supervised the latest medical examination in compliance with paragraph (a)(1) of this section did not recommend that that person be excluded from areas where personal exposure may exceed the action level;
(3) All respirators and personal protective clothing and equipment that will be used by that person while on the vessel meet the requirements of § 197.550(b) and § 197.555(c) or of 29 CFR 1910.1028; and
(4) All respirators that will be used by that person while on the vessel have been fitted and fit tested in accordance with § 197.550 (c) and (d) or with 29 CFR 1910.1028.

Note:
The employer need not furnish the required respirators and personal protective clothing and equipment to nonemployees.
(b) The certification required by paragraph (a) of this section must be in writing, list the items in paragraphs (a)(1) through (a)(4) of 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.
(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.
§ 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 § 197.550 and the personal protective clothing and equipment in compliance with § 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
§ 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 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]
§ 197.545
Program to reduce personal exposure.
(a) When personal exposure for an operation is over the applicable PEL as determined in compliance with § 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:
(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 § 197.550 and personal protective clothing and equipment in compliance with § 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.
§ 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 § 197.555 is chosen as the method or one of the methods in compliance with § 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 °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.
(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.

(iii) 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.
(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 § 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.

(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.

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 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.

(b) Physical data. (1) Boiling point (760 mm Hg): 80.1 °C (176 °F).
(2) Specific gravity (water = 1): 0.879.
(3) Vapor density (air = 1): 2.7.
(4) Melting point: 5.5 °C (42 °F).
(5) Vapor pressure at 20 °C (68 °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 °C (12 °F).
(2) Autoignition temperature: 580 °C (1076 °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.
(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.
Pt. 197, Subpt. C, App. C

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 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 ® 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.
(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 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.

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 °C before packing. The adsorbing section contains 100 mg of charcoal and the back-up section 50 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. × 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 µl) syringe, and other convenient sizes for making standards. One µl 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 (CS 2 ). 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 µl 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 °C injector temperature.
5. 250 °C detector temperature.
6. 100 °C column temperature.
5.4.4. Injection size. One µl.
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.
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 (µg/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=µg/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° and 760 mm) with following equation:
ppm = (mg/m ^3 )(24.46)/(78.11).
Where:
24.46 = molar volume of an ideal gas 25 °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 µl injections of a 1.283 µg/ml standard.

8.3 Storage data—Air Samples. Samples were generated at 1.03 ppm benzene at 80% relative humidity, 22 °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 °C and the other group was stored at ambient temperature (approximately 23 °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 × 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 µl syringe and other convenient sizes for making standards. 10 µl 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:
6.2.1. Mobile phase—Methyl alcohol/water, 50/50.
6.2.2. Analytical wavelength—254 nm.
6.2.3. Injection size—10 µl.
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 × 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 µg, 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 µl injections of a 0.10% by volume standard.

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.
(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 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 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.
(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.
(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.
(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.

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.

^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 § 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 work station, the requirement in § 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 § 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 § 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 °C (50 °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 § 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 § 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 § 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 § 199.175.

^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 § 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 § 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
(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 § 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 § 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 § 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 § 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 § 199.640(j).
(f) A vessel need not comply with the requirements for survival craft in § 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 § 199.262(a), vessels may carry a motor-propelled workboat or a launch that meets all the embarkation, launching, and recovery arrangement requirements in § 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 § 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 § 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 § 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 § 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.

(2) Stowage. Each buoyant apparatus, inflatable buoyant apparatus, or lifefloat must, in addition to meeting the general stowage requirements of § 199.130(a), be stowed as follows:
(i) Each inflatable buoyant apparatus must meet the liferaft stowage requirements in § 199.130(c).
(ii) Each buoyant apparatus and lifefloat must—
(A) Meet the liferaft stowage requirements in § 199.130(c) (1), (2), (3), (6), and (7); or
(B) Meet the liferaft stowage requirements in § 199.130(c) (1), (2), (3), and (6), and have lashings that can be easily released.
(iii) A painter must be secured to the buoyant apparatus or lifefloat by—
(A) The attachment fitting provided by the manufacturer; or
(B) A wire or line that encircles the body of the buoyant apparatus or lifefloat, that will not slip off, and that meets the requirements of paragraph (4)(iii) of this section.
(iv) If buoyant apparatus or lifefloats are arranged in groups with each group secured by a single painter—
(A) The combined mass of each group must not exceed 185 kilograms (407.8 pounds);
(B) Each buoyant apparatus or lifefloat must be individually attached to the group's single painter by its own painter, which must be long enough to allow the buoyant apparatus or lifefloat to float without contacting any other buoyant apparatus or lifefloat in the group;
(C) The strength of the float-free link and the strength of the group's single painter must be appropriate for the combined capacity of the group of buoyant apparatus or lifefloats;
(D) The group of buoyant apparatus or lifefloats must not be stowed in more than four tiers and, when stowed in tiers, the separate units must be kept apart by spacers; and
(E) The group of buoyant apparatus or lifefloats must be stowed to prevent shifting with easily detached lashings.
(3) Marking. Each buoyant apparatus or lifefloat must be marked plainly in block capital letters and numbers with the name of the vessel and the number of persons approved to use the device as shown on its nameplate.
(4) Equipment. Unless otherwise stated in this paragraph, each buoyant apparatus and lifefloat must carry the equipment listed in this paragraph and specified for it in table 199.640(j) of this section under the vessel's category of service.
(i) Boathook.
(ii) Paddle. Each paddle must be at least 1.2 meters (4 feet) long and buoyant.
(iii) Painter. The painter must—
(A) Be at least 30 meters (100 feet) long, but not less than three times the distance from the deck where the buoyant apparatus, inflatable buoyant apparatus, or lifefloats are stowed to the vessel's waterline with the vessel in its lightest seagoing condition;
(B) Have a breaking strength of at least 6.7 kiloNewtons (1,500 pounds-force), or if the capacity of the buoyant apparatus or lifefloat is 50 persons or more, have a breaking strength of at least 13.4 kiloNewtons (3,000 pounds-force);
(C) If made of a synthetic material, be of a dark color or be certified by the manufacturer to be resistant to deterioration from ultraviolet light;
(D) Be stowed in such a way that it runs out freely when the buoyant apparatus or lifefloat floats away from the sinking vessel; and
(E) Have a float-free link meeting the requirements of part 160, subpart 160.073 of this chapter secured to the end of the painter that is attached to the vessel, that is of the proper strength for the size and number of the buoyant apparatus or lifefloats attached to the float-free link.
(iv) Self-igniting light. The self-igniting light must be approved under approval series 161.010 and must be attached to the buoyant apparatus or lifefloat by a 12-thread manila or equivalent lanyard that is at least 5.5 meters (18 feet) long.
