D1.0
CL1-0
D1.1 In every ship which is required by this paragraph to be provided with fire pumps operated by power, the diameter of the firemain and of the water service pipes connecting the hydrants hereto shall be sufficient for the effective distribution of the maximum discharge required by this paragraph from—
- D1.1.1where only one pump is required that pump;
- D1.1.2where 2 such pumps are so required, both pumps operating simultaneously; or
- D1.1.3where more than 2 such pumps are so required, the 2 largest of such pumps operating simultaneously provided that in any ship other than a passenger ship the diameter of the fireman and of the water service pipes shall be required to be sufficient only for the discharge of 140 cubic metres per hour.
D1.2 Where the fire pumps required by this paragraph are discharging the quantity of water required by paragraph D1.1 through adjacent fire hydrants in any part of the ship to which are coupled fire hoses fitted with nozzles of sizes specified in item paragraph D2.0 of this Appendix the following minimum pressure shall be capable of being maintained at any hydrant;
- D1.2.1In any passenger ship—
- (a)of 4000 tons and over — 310 kpa; or
- (b)of 1000 tons and over but less than 4000 tons — 275 kpa; or
- (c)of less than 1000 tons — 200 kpa.
- D1.2.2In any ship other than a passenger ship—
- (a)of 6000 tons and over — 275 kpa; or
- (b)of 1000 tons and over but less than 6000 tons — 255 kpa; or
- (c)of less than 1000 tons — 200 kpa.
D1.3 Where any ship is required by this paragraph to provide 2 jets of water under the conditions required by this paragraph, hydrants sufficient in number shall be so positioned as to enable at least 2 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.
D1.4 Where any ship is required by this paragraph to provide one jet of water under the conditions required by this paragraph, 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.
D1.5 The firemain shall have no connections other than those necessary for fire-fighting, washing down including anchor wash.
D1.6 Materials readily rendered ineffective by heat shall not be used for fire mains unless adequately protected. The pipes and fire hydrants shall be so placed that the fire hoses may be easily coupled to them and operated without kinking.
D1.7 In ships which may carry deck cargo, the fire hydrants shall be so placed that they are always readily accessible and the pipes shall be so arranged as far as practicable to avoid risk of damage by such cargo. 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.
D1.8 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.
D1.9 The water pipes shall not be made of cast iron and if made of iron or steel shall be galvanised.
D1.10 Where wash deck lines are not self-draining, suitable drain cocks acceptable to the Chief Executive Officer or a surveyor shall be fitted to avoid damage by frost.
D1.11 When a fire pump required by this paragraph is delivering water through one of the holes and nozzles provided the pressure at any hydrant in the ship shall not exceed 690 kilopascals.
D1.12 In any tanker, isolation valves shall be fitted in the fire main at poop front in a protected position and on the tank deck at intervals of not more than 40 metres to preserve the integrity of the fire main system in case of fire or explosion.
D1.13 In any ship—
- (a)isolating valves shall be fitted in an easily accessible position outside the machinery spaces to separate the paragraph of the fire main within the machinery space containing the main fire pump or pumps from the rest of the fire main; and
- (b)the fire main shall be so arranged that when the isolating valves are shut all the hydrants on the ship, except those in the machinery space referred to above, can be supplied with water by a fire pump not located in that machinery space through pipes which do not enter that space; and
- (c)the Chief Executive Officer or a surveyor may permit short lengths of the emergency fire pump suction and discharge piping to penetrate the machinery space if it is impracticable to route it externally, provided that the integrity of the fire main is maintained by the enclosure of the piping in a substantial steel casing.
