Separation of Accommodation Spaces from Other Enclosed Spaces
44. The bulkheads and decks separating accommodation spaces from other enclosed spaces including machinery and cargo spaces shall consist of “A” Class divisions.
Protection of Stairways
45. (1) Every stairway within an accommodation space or service space shall be of steel frame construction and shall lie within an enclosure constructed of “A” Class divisions, provided that
(a) a stairway serving only two decks shall not be required to be enclosed by “A” Class divisions at more than one deck; and
(b) a stairway in a public room shall not be required to be so enclosed if it lies wholly within the room.
(2) The Board may exempt any ship, being a ship in which Method II of fire protection (within the meaning of section 52) has been adopted, from the requirements of subsection (1) in relation to any stairway that it is satisfied is an auxiliary stairway adequately protected by sprinklers.
(3) Every opening in a bulkhead forming part of a stairway enclosure shall be provided with a means of closure that shall be permanently attached thereto; the means of closure shall be as effective as the bulkhead in resisting fire, and shall be self-closing unless it is a watertight door.
(4) Every stairway enclosure shall communicate directly with the corridors adjacent thereto and shall have an area sufficient to prevent congestion, having regard to the number of persons likely to use the stairway in an emergency; every such enclosure shall contain as little accommodation space or service space as is practicable in the circumstances.
Protection of Lifts and Vertical Trunks for Light and Air
46. (1) In every ship every lift trunk, and every light-and-air and similar trunk in an accommodation space or service space shall be constructed of “A” Class divisions, provided that a lift trunk within a stairway enclosure shall not be required to be insulated; every door in such a trunk shall be constructed of steel or other incombustible material and shall be as effective as the trunk in resisting fire.
(2) Every lift trunk shall be so fitted as to prevent the passage of smoke and flame from one between decks to another and shall be provided with means of closure that will enable draught and smoke to be controlled.
(3) If a light-and-air or similar trunk communicates with more than one between decks space and smoke and flame may be conducted from one between decks to another, smoke shutters shall be fitted so as to enable each such space to be isolated in the event of fire.
(4) Every other trunk shall be so constructed as not to afford a passage for fire from one between decks or compartment to another.
Protection of Control Stations
47. (1) Every control station shall be separated from the rest of the ship by bulkheads and decks consisting of “A” Class divisions.
(2) The radio room shall not be situated directly above any stairway and shall be so situated as to minimize the risk of fire reaching it by way of stairways. An emergency means of escape, preferably to the open deck, shall be provided.
- SOR/2000-264, s. 2.
Protection of Other Rooms
48. (1) In every ship the boundary bulkheads separating a galley, baggage room, mail room, store room, paint room, lamp room, or any similar space from any other space shall consist of “A” Class divisions.
(2) Spaces appropriated for the storage of highly flammable stores shall be so constructed and situated as to minimize the danger to persons on board in the event of fire.
