Where practicable fire hoses shall be connected to the hydrants in such (3) Notwithstanding the requirements of subregulation (1) and (2), the Administration may increase the required number of fire hoses so as to ensure that hoses in sufficient number are Merchant Ships (Registration) 169 available and accessible at all times, having regard to the type of ship and the nature of trade in which the ship is engaged. (4) A single length of fire hose should not exceed 18m. (5) Fire hoses shall be oil-resistant and of approved material. (6) Fire hoses of unlined canvas shall have a diameter of not less than 64mm. Hoses of at least 45mm internal diameter having a throughput comparable to that of 64mm internal diameter unlined canvas at corresponding pressure may be used. Fire hoses of an internal diameter not less than 32mm may be accepted in ships of less than 150 gross tonnage and in the accommodation spaces of all ships. (7) Unless one fire hose and nozzle is provided for each hydrant, there shall be complete interchangeability of fire hose couplings. (8) Fire hoses provided in compliance with these requirements shall not be used for any purpose other than fire fighting or testing of the fire appliances.
