Inland Waters Small Passenger Boat Code 7 MACHINERY 7.1 General 7.1.1 Machinery, fuel tanks and associated piping systems and fittings should be fit for purpose and be of a design and construction adequate for the service for which they are intended. Moving parts, hot surfaces and other hazards should be installed and protected so as to minimise danger to persons during normal movement about the vessel. Materials should be fire resistant or otherwise protected from fire. Plastic fittings at the Hull are not recommended. 7.1.2 A vessel should be provided with a fuel tank of sufficient capacity for the main engines, and its area of operation. All fuel tanks vents should be fitted with a flame gauze as required by BS/EN/ISO 10088, and carried to at or above tank filling plate level and where there should be no danger from escaping fuel or vapour. 7.1.3 Where the machinery is in its own dedicated compartment and remote from the operator, means should be provided to isolate a source of fuel, which may feed a fire. A valve or cock, which can be shut from a position outside the engine space should be fitted in the fuel-feed pipe, as close to the fuel tank as possible. Where the machinery is situated directly below the operator, and within easy reach for control and isolation in event of emergency, these conditions need not apply. Petrol tanks for outboards motors should have quick connection shut off devices. 7.1.4 Measures should be taken to prevent spillage and build up of flammable vapours in any part of the vessel, including bilges during fueling. 7.1.5 Vessels should have an efficient and reliable starting mechanism. Where the means of starting is by battery, charging facilities for the battery should be available. 7.1.6 In CATEGORY C and D WATERS: where the sole means of starting is by battery, there should be a duplicate battery connected to the starter motor by a “change over switch” so that either battery or other means of obtaining power can be used to start the engine. 7.1.7 All inflatable boats, boats fitted with buoyant collar, and open boats that achieve planing speed, when fitted with remote throttle controls, should be fitted with a kill cord, to be used at all times during navigation. 7.5 LPG powered engines 7.5.1 An LPG powered propulsion engine should comply with The Liquid Petroleum Gas Association Code of Practice No. 18. 7.5.2 Conversions of engines to dual fuel operation, where LPG constitutes one of the fuels used, are not considered appropriate.
