2,000 tons, not being passenger ships, and provided that if two or more spaces containing boilers or machinery are not entirely separate they shall for the purposes of this regulation be considered as forming one space.
(12) When carbon dioxide is used as the extinguishing medium for a space containing any oil-fired boiler or oil fuel installation, a quantity of gas which can be discharged without danger to the operator shall be available for manual application, by means of a suitable applicator, in the firing area of the boiler and in the vicinity of the oil fuel unit.
(13) When carbon dioxide is used as the extinguishing medium both for cargo spaces and for spaces containing boilers or machinery the quantity of gas shall not be required to be more than the maximum required either for the largest cargo compartment or machinery space.
(14) For the purpose of paragraphs (10), (11), (12), (13), (15) and (16) the volume of gas shall be calculated at 9 cubic feet to the pound.
(15) When carbon dioxide is used as the extinguishing medium for any space containing boilers or machinery the fixed piping system shall be such that 85 per centum of the gas required to provide the concentration referred to in paragraph (11) when applied to the space concerned can be discharged into that space within two minutes.
(16) Means shall be provided for giving audible warning to persons within the space when carbon dioxide other than that specified in paragraph (12) is about to be released into any working space.
(17) When a system producing inert gas is used to provide smothering gas in a fixed fire smothering installation for cargo spaces, it shall be capable of producing hourly a volume of free gas at least equal to 25 per centum of the gross volume of the largest compartment protected in this way for a period of 72 hours.
(18) When steam is used as the extinguishing medium in cargo spaces the boiler or boilers available for supplying steam shall have an evaporation of at least one pound of steam per hour for each 12 cubic feet of the gross volume of the largest cargo compartment.
(19) The arrangements shall be such that steam will be available immediately and will not be dependent on the lighting of boilers and that it can be supplied continuously until the end of the voyage in the quantity required by this paragraph in addition to any steam necessary for the normal requirements of the ship including propulsion and that provision is made for extra feed water necessary to meet this requirement.
