49. In every ship any permanent deck sheathing within an accommodation space, service space, control station, stairway or corridor shall be such as will not readily ignite; in the case of ships that carry automobiles in a between deck space, the deck covering of any accommodation space that is located over the automobile storage space shall be incombustible material.
50. (1) The inlets of every air supply system and the outlets of every air exhaust system in every ship shall have readily accessible means by which they can be closed in the event of fire, and, wherever practicable, the system of ducts leading from each ventilating fan shall be within one main vertical zone.
(2) Every ship shall be equipped with two master controls, situated as far apart as is practicable, either of which shall be capable of stopping all the fans in the power ventilation systems of the ship, other than the ventilation systems in the machinery space; every power ventilation system serving the machinery space shall have two master controls, one of which shall be capable of being operated from outside such space; any exhaust ducts from galley ranges shall be constructed of “A” Class divisions that shall be insulated where the ducts pass through the accommodation spaces or service spaces.
(3) In the case of a ship the keel of which is laid after March 22, 1967, the exhaust duct from the galley range shall be fitted with
(a) a grease trap that is connected to the bottom of the duct and is readily removable for cleaning;
(b) a fire damper located in the bottom of the duct;
(c) a control switch, operable from within the galley, for shutting off the exhaust fan; and
(d) a fixed smothering system for extinguishing a fire within the duct.
Miscellaneous Items of Fire Protection
51. (1) Every air space enclosed behind a ceiling, panel or lining in the accommodation spaces or service spaces shall be divided by close fitting draught-stops, spaced not more than 14 m apart in the fore and aft direction, and shall be closed at each deck.
(2) Every ceiling, panel and lining referred to in subsection (1) shall be so constructed as to enable a fire patrol to detect any smoke originating in a concealed or inaccessible space, without impairing the efficiency of the fire protection of the ship; small holes in ceilings, panels and linings, protected by metal gauze, may be accepted for this purpose.
(3) The concealed surfaces of every bulkhead, lining, panelling, stairway, wood grounds and other structure in accommodation spaces and service spaces shall be such that they will be surfaces of low flame spread.
(4) Paints, varnishes or similar preparations shall not be applied if they contain a nitro-cellulose base, and fabrics containing nitro-cellulose shall not be fitted.
(5) Overboard scuppers, sanitary discharges or other outlets shall not be made of lead if they are close to the water line or in such a position that the fusing of the lead in the event of fire would give rise to a danger of flooding.
(6) The use of wood for the internal construction and equipment of galleys, bakeries and main pantries shall be restricted so far as is practicable.
(7) Every window and side scuttle in the accommodation spaces and service spaces shall be constructed with metal frames; the glass therein shall be retained by a metal ring or bead; if the window or side scuttle is in a position in which the fusion of the frame, ring or bead may give rise to a danger of flooding, the frame, ring or bead, as the case may be, shall consist of metal that is not likely to fuse in the event of fire; every window and side scuttle in such a ship opening on to a corridor or stairway shall be as effective in resisting fire as the bulkhead in which it is fitted.
(8) Skylights of engine and boiler spaces shall be capable of being closed from outside such spaces.
(9) Cellulose-based film shall not be used in cinematograph installations on board ship.
