15A.2.4 Fire hoses
15A.2.4.1 Fire hoses should not exceed 18 metres in length and, generally, the diameter of a lined hose for use with a powered pump should not be less than 45mm.
15A.2.4.2 Fire hoses and associated tools and fittings should be kept in readily accessible and known locations close to the hydrants or connections on which they will be used. Hoses supplied from a powered pump should have jet/spray nozzles (incorporating a shut-off facility) of diameter 19mm, 16mm or 12mm depending on fire fighting purposes. For accommodation and service spaces, the diameter of nozzles need not exceed 12mm. For machinery spaces and exterior locations, the nozzle size should be as to obtain the maximum discharge possible from two jets at the pressure referred to in 15A.2.2.1, from the smallest pump.
15A.2.4.3 Hydrants or connections in interior locations on the vessel should have hoses connected at all times. For use within accommodation and service spaces, proposals to provide a smaller diameter of hoses and jet/spray nozzles will be considered.
15A.2.4.4 The number of fire hoses and nozzles provided should correspond to the functional fire safety requirements, but be at least 3.
