1) Every ship shall be provided with fire pumps, fire mains, water service pipes, hydrants, hoses and nozzles capable of providing at least two jets of water, not emanating from the same hydrant, capable of reaching normally accessible parts of the ship while the ship is being navigated and any store room and any part of any cargo space when empty.
(2) Every ship of 4000 tons or above shall be provided with at least three independently driven fire pumps and every ship or less than 4000 tons shall be provided with at least two such pumps, and each such pump shall be capable of delivering two jets of water specified under clause (1) and in addition shall comply with the requirements specified in SOLAS.
(3) In every ship of 1000 tons and above, the arrangements of sea connections, pumps and sources of power for operating them shall be such as to ensure that fire in any one compartment will not put all the fire pumps out of action:
Provided that where arrangement in a ship is such that a fire in any one compartment could put all the fire-pumps out of action, there shall be provided in a position outside the machinery spaces, an independently driven power operated emergency fire pump and its source of power and sea connection. Such pump shall be capable of producing at least two jets of water from any two hydrants and hoses through nozzles which shall comply with the requirements specified while simultaneously maintaining a pressure of at least 2.1 bar (0.21 N/mm2) at any hydrant in the ship.
(4)(a) Every Ship shall be provided with a fire main, water service pipes, hydrants, hoses and nozzles which shall be so arranged that they comply with the requirements specified in rules
(b)In every ship of 1000 tons and above, the arrangement of fire pumps, fire mains and hydrants shall be such that at least one jet of water is immediately available from any one hydrant in an interior location. Arrangements shall also be made to ensure the continuation of the output of water by the automatic starting of a fire pump.
(5) In every ship at least one fire hose complete with nozzle shall be provided for every hydrant fitted in compliance with this rule and shall be used only for the purpose of extinguishing fire or for testing the fire extinguishing appliances at fire drills and surveys.
(6) In every ship.
- In any ro/ro cargo space or any special category space, the number of hydrants with holes shall be positioned near the accesses of such spaces and be so arranged that at least two jets of water, each from a single length of hose, not emanating from the same hydrant shall reach any part of such space.
- Where, in any machinery space of category A, access is provided at a low level from an adjacent shaft tunnel two hydrants fitted with hoses with dual-purpose nozzles shall be provided external to, but near the entrance of that machinery space. Where such access is not provided from a tunnel but is provided from other space or spaces there shall be provided in one of those spaces two hydrant; fitted with hoses with dual-purpose nozzles near the entrance to the machinery space of Category A. Such provisions need not be made when the tunnel or adjacent spaces are not part of an escape route.
Points to pounder :
Every fire pump required to be carried under these rules shall be operated by means of power other than the ships main engines except as expressly provided otherwise in these rules. Sanitary, ballast, bilge or general service pumps may be accepted by the Director General of Shipping as fire pumps provided they are not normally used for pumping oil and in case they are occasionally used for pumping or transferring fuel oil, suitable change-over arrangements are fitted and operating instructions are conspicuously displayed at the change-over position.
Any fire pump shall, when discharging the quantity of water required by above paragraphgraph through adjacent fire hydrants in any part of the ship from nozzles of sizes specified above be capable of maintaining the following pressure at any hydrant :
(a) in any passenger ship.
(i) of 4,000 tons and upwards :
3.1. bar (0.31 N/mm2)
(ii) of 1,000 tons and upwards but under 4,000 tons :
2.7 bar (0.27 N/mm2)
(iii) of under 1,000 tons :
2.1 bar (0.21 N/mm2)
(b) in any ship other than a passenger ship.
(i) of 6,000 tons and upwards :
2.7 bar (.027 N/mm2)
(ii) of 1,000 tons and upward but under 6,000 tons:
2.5 bar (0.25 N/mm2)
(iii) of under 1,000 tons :
2.1 bar (0.2) N/mm2)
