Exhibition of Plans

 In every ship there shall be provided for the guidance of the master of the ship plans showing for each deck the sections of the ship enclosed by “A” Class divisions and the sections of the ship enclosed by “B” Class divisions, together with particulars of the fire alarm and fire detecting systems, sprinkler installations and fire extinguishing appliances provided in the ship, the means of entry into and exit from the various compartments and decks, and of the ship’s ventilating system, including in particular the positions of the dampers thereof and the identification numbers of the ventilation fans serving each section of the ship, and such plans shall be protected by glass or similar material and shall be permanently affixed to a bulkhead, table or desk near the place from which the ship is normally navigated.

“A” and “B” Class Divisions

  •  (1) Every “A” Class division shall be constructed of steel or similar material, in either case stiffened so as to be capable of preventing the passage of smoke and flame throughout a standard fire test of 60 minutes duration; the division shall have an adequate insulating value having regard to the nature of the spaces adjacent thereto, and if the division is between spaces either of which contains adjacent combustible material, it shall be so insulated that, if either face of the division is exposed to a standard fire test of 60 minutes duration, the average temperature on the unexposed face of the division will not increase at any time during the test by more than 139°C above the initial temperature on that face nor shall the temperature at any one point thereon increase by more than 180°C above the initial temperature.

  • (2) Every “B” Class division shall be capable of preventing the passage of smoke and flame throughout a standard fire test of 30 minutes duration; every such division shall have an adequate insulating value having regard to the nature of the spaces adjacent thereto; the division shall be so constructed that, if either face thereof is exposed to a standard fire test of 30 minutes duration, the average temperature on the unexposed face of the division will not increase by more than 139°C above the initial temperature on that face, nor shall the temperature at any one point thereon increase by more than 180°C above the initial temperature, provided that any division that is constructed wholly of incombustible material shall be required to comply with the foregoing requirement relating to increase of temperature only during the first 15 minutes of a standard fire test.

  • SOR/95-254, s. 32.

Structure of the Ship

  •  (1) The hull, superstructure, structural bulkheads, decks and deckhouses of every ship shall be constructed of steel, but the Board may exempt any ship wholly or in part from the requirements of this subsection if it is satisfied that these parts are constructed of material equally resistant to fire.

  • (2) The hull, superstructure and deckhouses shall be subdivided by bulkheads consisting of “A” Class divisions into main vertical zones; the mean length of each zone, above the bulkhead deck, shall not exceed 40 m; any steps in the bulkheads shall consist of “A” Class divisions; in the case of railway car ferries (which does not include automobile carrying ships) where it is impracticable to fit fire-resisting bulkheads on the car deck, the car deck shall be completely isolated from the passenger spaces by fire-resisting bulkheads, doors and decks.

  • (3) Ships of Class I to Class IV and Class VI and Class VII that are certified to carry more than 12 passengers and have vehicular decks for the carriage of automobiles or other vehicles with fuel in their tanks shall have fitted on each of those decks a sprinkler system that complies with the requirements of the Fire Detection and Extinguishing Equipment Regulations.

  • (4) Where a sprinkler system is fitted on a vehicular deck, approved automatic water curtains complying with the requirements of the Fire Detection and Extinguishing Equipment Regulations may be substituted for main vertical zone “A” Class bulkheads.

  • (5) Any portions of such divisions that extend above the ship’s bulkhead deck shall, whenever possible, be in line with watertight subdivision bulkheads situated immediately below the bulkhead deck and shall extend from deck to deck and to the ship’s shell plating and, in the case of a deckhouse, to the external plating thereof; the insulation of such bulkheads shall be extended for a suitable distance at the bulkhead boundaries, but in no case less than 380 mm.

  • (6) Exits shall be provided from spaces between fire-resisting bulkheads and shall be independent of the doors in such bulkheads; they shall be so arranged that they will not act as conductors of fire from one deck to another; such exits shall be so arranged that all persons accommodated within spaces that are bounded by fire-resisting bulkheads will be able to escape from such spaces to an open deck or to spaces within other compartments that will lead to an open deck or to a place of safety.

  • SOR/95-254, s. 32.
