(Enacted 1991) Cap 369R reg 18 (1) Paints, varnishes and other surface materials having a nitrocellulose or other highly flammable base shall not be used in accommodation spaces, machinery spaces or control stations. (2) Pipes intended to convey oil or other flammable liquids shall be of a material acceptable to the Certifying Authority having regard to the risk of fire. (3) Overboard scuppers, sanitary discharges or other outlets close to or below the waterline shall not be of a material likely to fail in the event of fire and thereby give rise to a danger of flooding. (4) Cellulose-nitrate film shall not be used in cinematograph installations. (Enacted 1991) Cap 369R reg 19 (a) Subject to the provisions of regulation 1(6), in every ship to which these regulations apply the skylights to spaces containing main propulsion machinery or oil-fired boilers or auxiliary internal combustion type machinery of a total power of 746 kilowatts or over shall be capable of being closed and, where practicable, opened from outside the space in the event of fire and, where they contain glass panels, such panels shall be of fire resisting construction fitted with wire reinforced glass and shall have external, permanently attached shutters of steel or other equivalent material. (b) Windows may be fitted in engine casings provided that the Director is satisfied that they are necessary and will not constitute a fire hazard. Where such windows are fitted they shall be of a non-opening type and shall be of fire resisting construction fitted with wire reinforced glass and shall have external, permanently attached shutters of steel or other equivalent material. (Enacted 1991) Cap 369R reg 20 Boilers and machinery - general (1) In every ship to which these regulations apply the machinery, boilers and other pressure vessels shall be of a design and construction adequate for the service for which they are intended and shall be so installed and protected as to reduce to a minimum any danger to persons on board. (2) Without prejudice to the generality of the foregoing, means shall be provided which will prevent overpressure in any part of such machinery, boilers and other pressure vessels, and in particular every boiler and every unfired steam generator shall be provided with not less than two safety valves: only one safety valve need be fitted in every boiler and every unfired steam generator if the Director is satisfied that adequate protection against overpressure is provided. (Enacted 1991) Cap 369R reg 21 Boilers and other pressure vessels (1) In every ship to which these regulations apply every boiler or other pressure vessel and its respective mountings shall, before being put into service for the first time, be subjected to a hydraulic test to a pressure suitably in excess of the working pressure which will ensure that the boiler or other pressure vessel and its mountings are adequate in strength and design for the service for which it is intended and having regard to- (a) the design and the material of which it is constructed; (b) the purpose for which it is intended to be used; and (c) the working conditions under which it is intended to be used,and every such boiler or other pressure vessel and its respective mountings shall be maintained in an efficient condition. (2) In every such ship provision shall be made which will facilitate the cleaning and inspection of every pressure vessel. (Enacted 1991) Cap 369R reg 22 Machinery (1) In every ship to which these regulations apply main and auxiliary machinery essential for the propulsion and safety of the ship shall be provided with effective means of control and the machinery shall be capable of being brought into operation when initially no power is available in the ship. (2) In every such ship where risk from over-speeding of machinery would otherwise exist, means shall be provided to ensure that the safe speed is not exceeded. (3) In every such ship where main or auxiliary machinery or any parts of such machinery are subject to internal pressure, those parts shall, before being put into service for the first time, be subjected to a hydraulic test to a pressure suitably in excess of the working pressure having regard to- (a) the design and the material of which they are constructed; (b) the purpose for which they are intended to be used; and (c) the working conditions under which they are intended to be used,and such parts shall be maintained in an efficient condition. (Enacted 1991) Cap 369R reg 23 Means for going astern Every ship to which these regulations apply shall have sufficient power for going astern to secure proper control of the ship in all normal circumstances. (Enacted 1991) Cap 369R reg 24 Shafts In every ship to which these regulations apply every shaft shall be so designed and constructed that it will withstand the maximum working stresses to which it may be subjected, with a factor of safety which is adequate having regard to - |
