Section 46 in The Merchant Shipping (Fire Appliances) Rules, 1969
46. Means for stopping machinery, shutting off oil fuel suction pipes and closing of openings.
(1)In every ship to which these rules apply there shall be provided means for stopping ventilating fans serving machinery, accommodation and cargo spaces. For machinery and cargo spaces there shall be provided means for closing all skylights, doorways, ventilators, annular spaces round the funnels and other openings to such places. Such means shall be capable of being operated from positions outside the said spaces which would not be made inaccessible by a fire within such spaces.(2)In every ship to which these rules apply machinery driving (forced or induced) draught fans, oil fuel transfer pumps, oil fuel unit pumps and other similar fuel pumps shall be fitted with remote controls situated outside the spaces in which such machinery or pumps are situated and such controls shall be capable of stopping such machinery or pumps in the event of fire in the said spaces.(3)In every ship to which these rules apply every pipe connected to any oil fuel storage, settling or daily service tank, not being a double bottom tank, which if damaged would permit discharge of contents so as to cause a fire hazard, shall be fitted with a valve or cock which shall be secured to the tank to which it is connected and which shall be capable of being closed from a readily accessible position outside the space in which the tank is situated, provided that in case of any inlet pipe to such a tank non-return valve, similarly secured to the tank may be substituted. In the case of an oil deep tank tranversed by any shaft or pipe tunnel a valve shall be fitted on the tank, but an additional valve or valves may be fitted on the pipe line or lines outside the tunnel or tunnels to enable control to be exercised in the event of fire.
