Hull Construction Regulations
149 (1) Every bulkhead required by Table I to section 148 to have a ‘B-0’ 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 the external boundaries of the main hull and superstructures required by subsection 146(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.
(3) 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.
