Hull Construction Regulations (C.R.C., c. 1431)

• 208. (1) Where the external boundaries of the main hull and superstructures required by subsection 206(1) to be constructed of steel or an equivalent material are not required to have an ‘A’ Class fire rating, those external boundaries may be pierced for the fitting of doors, windows and sidescuttles.

• (2) To avoid the risk of heat transmission at intersections and terminal points of thermal barriers, the insulation of the bulkhead or deck having the higher fire rating shall be extended at least

  • (a) 380 mm beyond the intersection or terminal point if the bulkhead or deck is constructed of steel; or

  • (b) 450 mm beyond the intersection or terminal point if the bulkhead or deck is constructed of aluminum.

• 209. (1) Every bulkhead required by Table I to section 207 to have a ‘B’ Class fire rating shall extend from deck to deck and to the shell or other boundaries unless the bulkhead terminates at a continuous ‘B’ Class ceiling or continuous ‘B’ Class lining.

• (2) Where Method IC is adopted all bulkheads that are not required by Table I to section 207 to have an ‘A’ Class fire rating or ‘B’ Class Fire rating shall be at least of ‘C’ Class construction.

• (3) Where Method IIC is adopted, no restrictions apply in respect of the construction of bulkheads that are not required by Table I to section 207 to have an ‘A’ Class fire rating or ‘B’ Class fire rating or to be of ‘C’ Class construction.

• (4) Where Method IIIC is adopted, no restrictions apply in respect of the construction of bulkheads that are not required by Table I to section 207 to have an ‘A’ Class fire rating or a ‘B’ Class fire rating or to be ‘C’ Class divisions, but the area of any accommodation space or groups of spaces bounded by continuous ‘A’ Class divisions or ‘B’ Class divisions shall not exceed 50 m².

• 210. (1) Where Method IC is adopted, all linings, ceilings, draught stops and associated grounds in accommodation spaces, service spaces and control stations shall be made of non-combustible materials.

• (2) Where Method IIC or Method IIIC is adopted, all linings, ceilings, draught stops and associated grounds in corridors and stairway enclosures that serve accommodation spaces, service spaces or control stations shall be made of non-combustible materials.

211. Sections 212 to 221 apply where Method IC, Method IIC or Method IIIC is adopted.

• 212. (1) Subject to subsections (2) and (3), all insulation shall be composed of non-combustible materials.

• (2) Insulation in cargo spaces or refrigerated compartments of service spaces may be composed of combustible materials.

• (3) Vapour barriers, adhesives used in conjunction with insulation and insulation on pipe fittings for cold service systems may be made of combustible materials if they are kept to the minimum quantity practicable and their exposed surfaces have low flame spread characteristics.
