46 C.F.R. Subpart 95.50—Hand Portable Fire Extinguishers and Semiportable Fire Extinguishing Systems, Arrangements and Details
Title 46 - Shipping
(a) The provisions of this subpart, with the exception of §95.50–90, shall apply to all vessels, other than unmanned barges and fishing vessels, contracted for on or after November 19, 1952. Such vessels contracted for prior to November 19, 1952, shall meet the requirements of §95.50–90. (a) Hand portable fire extinguishers and semiportable fire extinguishing systems shall be classified by a combination letter and number symbol. The letter indicating the type of fire which the unit could be expected to extinguish, and the number indicating the relative size of the unit. (b) The types of fire will be designated as follows: (1) “A” for fires in ordinary combustible materials where the quenching and cooling effects of quantities of water, or solutions containing large percentages of water, are of first importance. (2) “B” for fires in flammable liquids, greases, etc., where a blanketing effect is essential. (3) “C” for fires in electrical equipment where the use of nonconducting extinguishing agent is of first importance. (c) The number designations for size will start with “I” for the smallest to “V” for the largest. Sizes I and II are considered hand portable fire extinguishers and sizes III, IV, and V are considered semiportable fire extinguishing systems which shall be fitted with suitable hose and nozzle or otherpracticable means so that all portions of the space concerned may be covered. Examples of size graduations for some of the typical hand portable and semiportable fire extinguishing systems are set forth in Table 95.50–5(c). (d) All hand portable fire extinguishers and semiportable fire extinguishing systems shall have permanently attached thereto a metallic name plate giving the name of the item, the rated capacity in gallons, quarts, or pounds, the name and address of the person or firm for whom approved, and the identifying mark of the actual manufacturer. (e) Vaporizing-liquid type fire extinguishers containing carbon tetrachloride or chlorobromomethane or other toxic vaporizing liquids shall be removed from all vessels. (a) Approved hand portable fire extinguishers and semiportable fire extinguishing systems shall be installed in accordance with Table 95.50–10(a). The location of the equipment shall be to the satisfaction of the Officer in Charge, Marine Inspection. Nothing in this paragraph shall be construed as limiting the Officer in Charge, Marine Inspection, from requiring such additional equipment as he deems necessary for the proper protection of the vessel. (b) Semiportable fire extinguishing systems shall be located in the open so as to be readily seen. (c) If hand portable fire extinguishers are not located in the open or behind glass so that they may be readily seen, they may be placed in enclosures together with the fire hose, provided such enclosures are marked as required by §97.37–15 of this subchapter. (d) Hand portable fire extinguishers and their stations shall be numbered in accordance with §97.37–23 of this subchapter. (e) Hand portable or semiportable extinguishers, which are required on their nameplates to be protected from freezing, shall not be located where freezing temperatures may be expected. (a) For all vessels other than motorboats spare charges shall be carried for at least 50 percent of each size and each variety, i.e. foam, soda-acid, carbon dioxide, etc., of hand portable fire extinguisher required by §95.50–10(a). However, if the unit is of such variety that it cannot be readily recharged by the vessel's personnel, one spare unit of the same classification shall be carried in lieu of spare charges for all such units of the same size and variety. (b) Spare charges shall be so packaged as to minimize the hazards to personnel while recharging the units. Acid shall be contained in a Crown stopper type of bottle. (a) The frame or support of each size III, IV, and V fire extinguisher required by Table 95.50–10(a) must be welded or otherwise permanently attached to a bulkhead or deck. (b) If an approved size III, IV, or V fire extinguisher has wheels and is not required by Table 95.50–10(a), it must be securely stowed when not in use to prevent it from rolling out of control under heavy sea conditions. [CGD 77–039, 44 FR 34133, June 14, 1979] (a) Vessels contracted for prior to November 19, 1952, shall meet the following requirements: (1) The provisions of §§95.50–5 through 95.50–15 shall be met with the exception that existing installations in safety areas and service spaces may be maintained if in the opinion of the Officer in Charge, Marine Inspection, they are in general agreement with the degree of safety prescribed by Table 95.50–10(a). In such cases, minor modifications may be made to the same standard as the original installation: Provided, That in no case will a greater departure from the standards of Table 95.50–10(a) be permitted than presently exists.
