(1) Each portable fire extinguisher must be inspected, maintained, and hydrostatically tested as required by Chapter 4 of NFPA 10 with the frequency specified by NFPA 10. Carbon-dioxide and halon portable fire extinguishers must be refilled when the weight loss of net content exceeds that specified for fixed systems by Table 132.350. Further, each must be examined for excessive corrosion and for general condition. A tag issued by a qualified servicing facility, and attached to each extinguisher, will be acceptable evidence that the necessary maintenance has been conducted.

(2) Each semiportable fire extinguisher and each fixed fire-extinguishing system must be—

(i) Inspected and tested as required by Table 132.350 of this subpart;

(ii) Inspected, tested, and marked as required by §§ 147.60 and 147.65 of this chapter;

(iii) Inspected to ensure that piping, controls, and valves are in good general condition with no excessive corrosion; and

(iv) Inspected and tested to determine that alarms and ventilation shutdowns for each fire-extinguishing system operate properly.

(3) The fire-main system must be operated, and the pressure checked at the remotest and highest outlets. Each fire hose must be subjected to a test pressure, equivalent either to the maximal pressure to which it may be subjected in service or to 690 kPa (100 psi), whichever is greater.

(4) All systems for detecting smoke and fire, including sensors and alarms, must be inspected and tested.

(a) Each vessel of less than 100 gross tons must carry one fire axe.

(b) Each vessel of 100 or more gross tons must carry two fire axes.

(c) Each fire axe must be so placed as to be readily available in an emergency.

(d) Each fire axe must be so placed in the open or behind glass that it is readily visible, except that, if the enclosure is marked in compliance with § 131.830 of this subchapter, the axe may be placed in an enclosure together with the fire hose.

(a) Two emergency outfits, stored for use in widely separated, accessible locations, are required on all OSVs of at least 6,000 GT ITC (500 GRT if GT ITC is not assigned) that have cargo tanks that exceed 15 feet in depth, measured from the tank top to the lowest point at which cargo is carried.

(b) Each emergency outfit must have on board the following equipment:

(1) One pressure-demand, open-circuit, self-contained breathing apparatus, approved by the National Institute for Occupational Safety and Health and having at a minimum a 30-minute air supply, a full facepiece, and a spare charge.

(2) One lifeline with a belt or a suitable harness.

(3) One Type II or Type III flashlight constructed and marked in accordance with ASTM F1014—02 (incorporated by reference, see § 125.180).

(4) One fire axe.

(5) One pair of boots and gloves of rubber or other electrically nonconducting material.

(6) One rigid helmet that provides effective protection against impact.

(7) One set of protective clothing of material that will protect the skin from the heat of fire and burns from scalding steam. The outer surface must be water resistant.

(c) Lifelines must be of steel or bronze wire rope. Steel wire rope must be either inherently corrosion resistant or made so by galvanizing or tinning. Each end must be fitted with a hook with keeper having a throat opening that can be readily slipped over a 5/8-inch bolt. The total length of the lifeline must be dependent upon the size and arrangement of the vessel, and more than one line may be hooked together to achieve the necessary length. No individual lifeline may be less than 50 feet in length. The assembled lifeline must have a minimum breaking strength of 1,500 pounds.

(a) When carrying fixed independent tanks on deck or portable tanks in compliance with § 125.110 of this subchapter, each vessel must also comply with §§ 98.30-37 and 98.30-39 of this chapter.

(b) When carrying portable tanks in compliance with § 125.120 of this subchapter, each vessel must also comply with 49 CFR 176.315.

(a) This section applies to OSVs of at least 6,000 GT ITC (500 GRT if GT ITC is not assigned).

(b) Cargo tanks containing flammable or combustible liquids must not be located beneath the accommodations or machinery space. Separation by cofferdams is not acceptable for meeting this requirement.

(c) Except for OSVs complying with paragraph (d)(1) of this section, each OSV must carry at least two approved semiportable dry chemical fire extinguishers for the protection of all weather deck areas within 10 feet (3 m) of any tank openings, pumps, flanges, valves, vents, or loading manifolds. Each extinguisher must have—

(1) A minimum capacity of 135 kg. If the protected area exceeds 90 m 2, additional extinguishers must be provided to supply a total combined capacity of dry chemical in kilograms equal to the total combined protected area in square meters multiplied by 3;

(2) A minimum flow rate of 3 kg/min from each discharge hose;

(3) A sufficient number of discharge hoses of adequate length to protect the areas required above without moving any of the extinguishers; and

(4) The frame or support for each semi-portable dry chemical fire extinguisher welded or otherwise permanently attached to the vessel's structure.

(d) Each OSV with fixed cargo tanks that have an aggregate capacity of 3,000 cubic meters or more intended for the carriage of flammable or combustible liquids with a closed-cup flashpoint of 60 °C or below must have:

(1) An approved fixed-deck foam system arranged as follows:

(i) If the flammable or combustible liquid tanks extend vertically to the weather deck, the foam system must comply with §§ 34.20-10 and 34.20-15 of this chapter, and protect the entire weather deck cargo area, including any tank openings, pumps, flanges, valves, vents, or loading manifolds. If petroleum products are carried, the minimum foam system discharge rate in liters per minute must be determined by multiplying the total cargo deck area by 6 lpm/m 2. If polar solvent cargoes are carried, the minimum foam system discharge rate in liters per minute must be determined by multiplying the total cargo deck area by 10 lpm/m 2, unless the approved foam system design manual specifies a different rate for the cargoes carried.

(ii) If the flammable or combustible liquid tanks do not extend vertically to the weather deck, the foam system must be capable of protecting all weather deck areas within 10 feet (3 m) of any tank openings, pumps, flanges, valves, vents, or loading manifolds. The foam system must consist of at least one hoseline, and either fixed-foam monitors or fixed-foam nozzles that provide foam coverage of all required areas. The minimum foam system discharge rate must be calculated in accordance with paragraph (d)(1)(i) of this section, using the combined horizontal area of all parts of the deck requiring protection, instead of the total deck area.

(iii) All foam liquid concentrate must be compatible with all flammable or combustible liquids carried.

(iv) Sufficient foam liquid concentrate must be carried to allow operation of the system at its maximum discharge rate for at least 20 minutes.

(2) A fixed-gas fire-suppression system complying with § 34.05-5(a)(4) of this chapter, or other approved fire-extinguishing system determined acceptable by the Commandant, for the protection of any accessible below-deck cargo pump rooms or other spaces that have tank openings, pumps, flanges, valves, or loading manifolds associated with tanks carrying flammable or combustible liquids with a closed cup flashpoint of 60 °C or below.
