  "text": "(1) In every vessel of 24.4 metres in length and over to which these Rules apply oil fuel shall be effectively isolated from other liquids. The oil fuel pumping arrangements shall permit the oil fuel to be transferred from any oil fuel storage tank or settling tank into another oil fuel storage tank or settling tank. Provision shall be made to prevent the accidental discharge or overflow of oil overboard. If drinking water or boiler feed water is stored in a tank adjacent to an oil fuel tank a coffer-dam shall be provided which will prevent contamination.\n(2) In every such vessel oil fuel tank sounding pipes shall not terminate in crew accommodation, but they may be installed in passage-ways.\n(3) In every such vessel oil fuel level indicators shall be accurate and fit for their intended service, and shall be of a type which does not require piercing of the lower part of the oil fuel tank. Tubular gauge glasses shall not be fitted to oil fuel tanks but suitably protected gauges having flat glasses of substantial thickness and self closing fittings may be used.\n(4) In every such vessel overflows from settling tanks and daily service tanks shall be led back to the storage tanks or to an overflow tank and means shall be provided to indicate when the tanks are overflowing.\n(5) In every such vessel where oil fuel tanks are alternatively used as liquid ballast tanks proper means shall be provided to isolate the oil fuel and ballast systems.\n(6) In every such vessel oil fuel filling stations shall be isolated from other spaces and be adequately drained and independently ventilated. Provision shall be made to prevent over-pressure in oil-filling pipe lines.\n(7) In every such vessel oil fuel pressure pipes shall be made of seamless steel or other suitable material having flanged joints and shall be properly installed and be led at such a height above the inner bottom as will facilitate inspection and repair. Every such pipe, joint and its fittings shall, before being put into service for the first time, be subjected to a test by hydraulic pressure to 28 kilogrammes force per square centimetre or to twice the maximum working pressure, whichever is the greater, and shall at any time thereafter be capable of withstanding such a test. Where such pipes are used for conveying heated oil they shall be situated in a position above the platform in well-lighted parts of the boiler room or engine room.\n(8) In every such vessel oil fuel pipes not being oil fuel pressure pipes shall be made of steel or other suitable material having flanged joints and shall be properly installed and be led at such a height above the inner bottom as will facilitate inspection and repair. Every such pipe, joint and its fittings shall, before being put into service for the first time, be subjected to a test by hydraulic pressure to 3.5 kilogrammes force per square centimetre or to twice the maximum working pressure, whichever shall be the greater, and shall at any time thereafter be capable of withstanding such a test.\n(9) In every such vessel steam heating pipes which may be in contact with oil shall be made of steel and, together with their joints, shall, before being put into service for the first time, be subjected to a test by hydraulic pressure to twice the maximum working pressure, and shall at any time thereafter be capable of withstanding such a test.\n(10) In every such vessel every suction pipe from any oil fuel tank situated above an inner bottom within a boiler room or engine room shall be fitted with a valve or cock secured to each tank to which the pipe is connected. Every such valve or cock fitted to an oil fuel suction pipe shall be so arranged that it may be closed both from the compartment in which it is situated and from a readily accessible position outside such compartment not likely to be cut off in the event of fire in that compartment. If any oil tank filling pipe is not connected to an oil fuel tank at or near the top of the tank, it shall be fitted with a non-return valve or with a valve or cock secured to the tank to which it is connected and so arranged that it may be closed from the compartment in which it is situated and also from a readily accessible position outside such compartment not likely to be cut off in the event of fire in that compartment.\n(11) In every such vessel master valves at the furnace fronts which control the supply of oil fuel to sets of burners shall be of quick-closing type and fitted in a readily accessible and conspicuous position. Provision shall be made to prevent oil from being turned on to any burner unless the burner has been correctly coupled up to the oil fuel supply line.\n(12) In every such vessel provision shall be made for oil fuel pressure pumps and transfer pumps to be stopped from a position outside the compartment in which the pumps are situated.",
