[接上页] (7) Relief valves shall be provided in conjunction with all fire pumps if the pumps are capable of developing a pressure exceeding the design pressure of the fire main, water service pipes, hydrants and hoses. (8) Such relief valves shall be so placed and adjusted as to prevent excessive pressure in any part of the fire main system. (9) Every centrifugal pump which is connected to the fire main shall be fitted with a non-return valve. (10) In every ship of Groups 1 and 2 to which these regulations apply, every emergency fire pump shall be situated in positions aft of the ship's collision bulkhead. Cap 369B reg 33 Fire main, water service pipes and hydrants (1) In every ship which is required by these regulations to be provided with fire pumps operated by power, the diameter of the fire main and of the water service pipes connecting the hydrants thereto shall be sufficient for the effective distribution of the maximum discharge required by these regulations from- (a) where only one pump is required by the regulations, that pump; or (b) where two such pumps are so required, both pumps operating simultaneously; or (c) where more than two such pumps are so required, the two largest of such pumps operating simultaneously:Provided that in any ship other than a passenger steamer the diameter of the fire main and of the water service pipes shall be required to be sufficient only for the discharge of 140 tons per hour. (2) When the fire pumps required by these regulations are discharging the quantity of water required by paragraph (1) through adjacent fire hydrants in any part of the ship from nozzles of sizes specified in regulation 34 the following minimum pressure shall be capable of being maintained at any hydrant- (a) in any passenger steamer- (i) of 4000 tons and upwards, 45 pounds per square inch; or (ii) of 1000 tons and upwards but under 4000 tons, 40 pounds per square inch; or (iii) of under 1000 tons, 30 pounds per square inch; and(b) in any ship other than a passenger steamer- (i) of 6000 tons and upwards, 40 pounds per square inch; or (ii) of 1000 tons and upwards but under 6000 tons, 37 pounds per square inch; or (iii) of under 1000 tons, 30 pounds per square inch.(3) Where any ship is required by these regulations to provide two jets of water under the conditions required by these regulations, hydrants sufficient in number shall be so positioned as to enable at least two jets of water not emanating from the same hydrant, one of which shall be from a single length of hose, to reach any part of the ship normally accessible to the passengers or crew while the ship is being navigated, and to any store room and any part of any cargo space when empty. (4) Where any ship is required by these regulations to provide one jet of water under the conditions required by these regulations, hydrants sufficient in number shall be so positioned as to enable one jet of water from a single length of hose to reach any part of the ship normally accessible to the passengers or crew while the ship is being navigated, and any store room and any part of any cargo space when empty. (5) In order to comply with this regulation- (a) the fire main shall have no connections other than those necessary for fire fighting and washing down; (b) materials readily rendered ineffective by heat shall not be used for fire mains unless adequately protected; (c) pipes and fire hydrants shall be so placed that the fire hoses may be easily coupled to them; (d) ships which may carry deck cargo the fire hydrants shall be so placed that they are always readily accessible and the pipes shall be arranged as far as practicable to avoid risk of damage by such cargo; (e) unless there is provided one fire hose and nozzle for each fire hydrant in the ship there shall be complete interchangeability of fire hose couplings and nozzles; (f) valves of the screw lift type or cocks shall be fitted in such positions on the pipes that any of the fire hoses may be removed while the fire pumps are at work; (g) the water pipes shall not be made of cast iron, and if made of iron or steel shall be galvanized; and (h) where wash deck lines are not self-draining suitable drain cocks shall be fitted to avoid damage by frost. Cap 369B reg 34 Fire hoses, nozzles, etc. (1) Fire hoses provided in compliance with these regulations shall not exceed 60 feet in length except that in ships having a moulded breadth of 90 feet or more the length of the fire hoses for exterior locations and for cargo spaces shall not exceed 90 feet in length. (2) Such hoses shall be made of closely woven flax canvas or other suitable material and shall be provided with couplings, branch-pipes and other necessary fittings, and with a plain nozzle in addition to any spray nozzle required by these regulations.
