### Merchant Shipping (Safety) (Fire Protection) (Ships Built On or After 1 September 1984) Regulations 《商船(安全)(防火)(1984年9月1日或之後建造的船舶)規例》

111. Application
Regulations 112 to 125 inclusive shall apply to ships of Classes VII, VII(A), VIII, VIII(A), IX and IX(A) of 500 tons or over and tankers of Classes VII(T), VIII(T), VIII(A)(T) and IX(A)(T) of 500 tons or over other than tankers to which Part VIII applies. 

112. Structure
(1) The hull, superstructures, structural bulkheads, decks and deckhouses shall be constructed of steel or other equivalent material except that the crowns and casings of machinery spaces of Category A shall be constructed only of steel.
(2) Where any part of the structure is of aluminium alloy, the following requirements shall apply—
(a) the insulation of aluminium alloy components of “A” Class divisions or “B” Class divisions, and supports of such divisions, shall be such that the temperature of the structural core does not rise more than 200oC above the ambient temperature at any time during a standard fire test of 60 minutes duration in the case of an “A” Class division and 30 minutes duration in the case of a “B” Class division; and
(b) the insulation of aluminium alloy components of columns, stanchions and other structural members required to support lifeboat and liferaft stowage, launching and embarkation areas, shall be such that the temperature rise limitation specified in paragraph (a) shall apply for 60 minutes duration.

112A. Helicopter decks
(1) Subregulations (2), (3) and (4) apply to a post 1992 ship (other than a post-1998 ship) having a helicopter deck. (L.N. 254 of 2018)
(1A) Subregulation (5) applies to a post-1998 ship. (L.N. 254 of 2018)
(2) Subject to subregulation (4), the helicopter deck shall be of steel equivalent fire-resistant construction.
(3) If the space below the helicopter deck is of a high fire risk, the insulation standard shall be to the satisfaction of the Director.
(4) If the Director so permits, the helicopter deck may be constructed of aluminium or other low melting metal construction that is not made equivalent to steel, except that—
(a) if the platform is cantilevered over the side of the ship, then, after the occurrence of a fire on the ship or on the platform, the platform shall undergo a structural analysis to determine its suitability for further use;
(b) if the platform is located above the ship’s deckhouse or similar structure—
(i) the deckhouse top and bulkheads under the platform shall have no openings;
(ii) all windows under the platform shall be provided with steel shutters;
(iii) after a fire on or in close proximity to the platform, the platform shall undergo a structural analysis to determine its suitability for further use.
(5) Provisions of helicopter facilities on a ship must be in accordance with the Standards for On-board Helicopter Facilities adopted by the International Maritime Organization by Resolution A.855(20). (L.N. 254 of 2018)

113. Method of fire protection
One of the following methods of protection shall be adopted in the accommodation and service spaces—
(a) Method IC—The construction of all internal divisional bulkheading shall be of non-combustible “B” Class divisions or “C” Class divisions without the installation of an automatic sprinkler fire detection and fire alarm system in the accommodation and service spaces, except as required by regulation 123; or
(b) Method IIC—An automatic sprinkler, fire detection and fire alarm system as required by regulation 123 shall be fitted for the detection and extinction of fire in all spaces in which fire might be expected to originate with no restriction on the type of internal divisional bulkheading; or
(c) Method IIIC—A fixed fire detection and fire alarm system, as required by regulation 123 shall be fitted in all spaces in which a fire might be expected to originate with no restriction on the type of internal divisional bulkheading, except that in no case shall the area of any accommodation space or spaces bounded by continuous “A” Class divisions and/or “B” Class divisions exceed 50 square metres subject to the requirements of regulation 114(4).

114. Bulkheads within accommodation spaces, service spaces and control stations
(1) All bulkheads which are required to be “B” Class divisions shall extend from deck to deck and to the shell or other boundaries, unless continuous “B” Class ceilings and/or linings are fitted on both sides of the bulkhead in which case the bulkhead may terminate at the continuous ceiling and/or lining.
(2) In ships where Method IC is adopted all bulkheads which are not required by this Part to be either “A” Class divisions or “B” Class divisions, shall be “C” Class divisions.
(3) In ships where Method IIC is adopted there shall be no restriction on the construction of bulkheads which are not required by this Part to be “A” Class divisions or “B” Class divisions except where “C” Class bulkheads are required in accordance with table 7 at the end of regulation 115.
(4) In ships where Method IIIC is adopted there is no restriction on the construction of bulkheads which are not required to be “A” Class divisions or “B” Class divisions except where “C” Class bulkheads are required in accordance with table 7 at the end of regulation 115. In no case shall the area of any accommodation space or spaces bounded by continuous “A” Class divisions and/or “B” Class divisions exceed 50 square metres provided that the Director may permit this area to be exceeded in public spaces.
