Method of Fire Protection

  •  (1) The accommodation spaces and service spaces in every cargo ship referred to in subsection 3(10) shall be constructed in accordance with one of the following methods of fire protection and shall comply with the requirements of this Part as are expressed to apply to ships in which that method has been adopted:

    • (a) Method IC: the construction in the accommodation spaces and service spaces of a system of internal division bulkheads consisting of ‘A’ Class divisions, ‘B’ Class divisions or ‘C’ Class divisions and the fitting of an automatic fire detection and alarm system in those spaces;

    • (b) Method IIC: the fitting of an automatic sprinkler system and an automatic fire detection and alarm system in the accommodation and service spaces with no restriction on the type of internal division bulkheads; and

    • (c) Method IIIC: the fitting of an automatic fire detection and alarm system in the accommodation spaces and service spaces with no restriction on the type of internal division bulkheads, but the area of any accommodation space or groups of spaces bound by an ‘A’ Class division or ‘B’ Class division shall not exceed 50 m2.

  • (2) The requirements set out in this Part for the use of non-combustible materials in the construction and insulation of the boundary bulkheads of machinery spaces and control stations and for the protection of stairway enclosures and corridors apply in respect of ships in which Method IC, Method IIC or Method IIIC has been adopted.

  • SOR/83-521, s. 4;
  • SOR/90-240, s. 11.

Main Structure

  •  (1) Subject to subsections (2) and (3), the main hull, structural bulkheads, decks, superstructures and deckhouses shall be constructed of steel or an equivalent material.

  • (2) Crowns and casings of machinery spaces of Category A shall be constructed of steel.

  • (3) Where any part of the main structure is constructed of aluminum alloy,

    • (a) the insulation of aluminum alloy components of ‘A’ Class divisions, other than divisions that are non-load-bearing, shall be such that the temperature of the structural core does not rise more than 200°C above the ambient temperature at any time during the first 60 minutes of the standard fire test;

    • (b) the insulation of aluminum alloy components of ‘B’ Class divisions, other than divisions that are non-load-bearing, shall be such that the temperature of the structural core does not rise more than 200°C above the ambient temperature at any time during the first 30 minutes of the standard fire test; and

    • (c) the insulation of aluminum alloy components of pillars, stanchions and other structural members supporting lifeboat and liferaft stowage areas, launching and embarkation areas, and ‘A’ Class divisions or ‘B’ Class divisions shall

      • (i) with respect to those structural members supporting lifeboat and liferaft stowage areas, launching and embarkation areas, and ‘A’ Class divisions, comply with the temperature rise limitation specified in paragraph (a), and

      • (ii) with respect to those structural members supporting ‘B’ Class divisions, comply with the temperature rise limitation specified in paragraph (b).
