WATER SUPPLY  Passenger ships:  of 1,000 gross tonnage and upwards such that at least one effective jet of water is immediately available from any hydrant in an interior location and so as to ensure the continuation of the output of water by the automatic starting of one required fire pump IN CARGO SHIPS:  there shall be immediate water delivery from the fire main system at a suitable pressure, either by remote starting of one of the main fire pumps with remote starting from the navigation bridge and fire control station Diameter of the fire mains Fire pumps in passenger ships of: 4,000 gross tonnage and upwards at least three less than 4,000 gross tonnage at least two in cargo ships of:1,000 gross tonnage and upwards at least two.

Fire hoses and nozzles  Fire hoses shall be of non-perishable material.  Each hose shall be provided with a nozzle and the necessary couplings.  in interior locations in passenger ships carrying more than 36 passengers, fire hoses shall be connected to the hydrants at all times. Fire hoses shall have a length of at least 10 m but not more than:  15 m in machinery spaces;  20 m in other spaces and open decks; and  25 m for open decks on ships with a maximum breadth in excess of 30 m. Fire Extinguishers Maintenance  The extinguishers should be examined annually by a competent person. During these examinations plastic collars etc. which may conceal the condition of the steel underneath should be removed. Each extinguisher should be provided with a sign indicating it has been examined.  Containers of permanently pressurised and non-permanently pressurised fire extinguishers should be hydraulically pressure tested every 10 years.  Carbon dioxide extinguishers and gas expellent cartridges of other extinguishers should be recharged or renewed if the loss of gas by weight In passenger ships, there shall be at least one fire hose for each of the hydrants. In cargo ships of 1,000 gross tonnage and upwards, the number of fire hoses to be provided shall be one for each 30 m length of the ship and one spare, but not less than five in all. May be increased if the administration requires , Ships carrying dangerous goods in addition be provided with three hoses and nozzles. Nozzles shall be of an approved dualpurpose type (i.e. spray/jet type) incorporating a shutoff.  Nozzles shall be dual-purpose type (i.e. spray/jet type) incorporating a shutoff.
