(1) Every stairway within accommodation spaces, service spaces and control stations shall be constructed of steel except where the Director may approve the use of other equivalent material. Every such stairway and lift shall lie respectively within an enclosure or trunk constructed of “A” Class divisions of “A-0” standard except that an isolated stairway serving only two decks shall only be required to be enclosed at one level by either “A” Class divisions of “A-0” standard or “B” divisions of “B-0” standard provided that the fire integrity of any bulkhead which separates a stairway from either a machinery space of Category A or a ro/ro cargo space shall be determined by reference to table 7 of regulation 115. (E.R. 1 of 2022)
(2) Every opening in a stairway enclosure and lift trunk shall be provided with a means of closure which shall be permanently attached thereto and which shall comply with the requirements of regulation 117 or 118 whichever is applicable.

117. Openings in “A” Class divisions
(1) Where an “A” Class division is pierced for the passage of electric cables, pipes, trunks, girders or beams or for other purposes, the arrangements shall be such that the effectiveness of the division in resisting fire is not thereby impaired.
(2) The construction of all doors and frames in “A” Class bulkheads, with the means of securing the doors when closed, shall provide resistance to fire as well as to the passage of smoke and flame, as far as is reasonably practicable, equivalent to that of the bulkheads in which the doors are situated. (L.N. 440 of 1993)
(3) Every door in an “A” Class bulkhead shall be so constructed that it can be opened and closed by one person from either side of the division.
(4) Every door in an “A” Class bulkhead which forms part of a stairway enclosure or lift trunk serving accommodation spaces, service spaces or control stations and every door in a casing of a machinery space of Category A shall be self-closing.
(5) Hold-back arrangements may be fitted to doors to which subregulation (4) refers provided that such arrangements—
(a) have remote release fittings of a type which in the event of disruption of the control system will automatically close the doors; and
(b) will permit each door to be closed manually.
(6) Doors fitted in boundary bulkheads of machinery spaces of Category A shall be reasonably gastight and self-closing.
(7) Watertight doors need not be insulated.
(8) Where ventilation ducts pass through “A” Class divisions the requirements of regulation 119 shall apply.

118. Openings in “B” Class divisions
(1) Where a “B” Class division is pierced for the passage of electric cables, pipes, trunks, girders or beams, or for other purposes, the arrangements shall be such that the effectiveness of the division in resisting fire is not thereby impaired.
(2) The construction of all doors and door frames in “B” Class bulkheads shall provide resistance to fire as well as the passage of flame, as far as is reasonably practicable, equivalent to that of the bulkheads in which the doors are situated.
(3) The number of ventilation openings in “B” Class divisions shall be kept to a minimum and shall be provided as far as is reasonably practicable only in the lower part of a door and fitted with a grille constructed of steel or under a door except that such openings shall not be provided in a door in a “B” Class division forming a stairway enclosure. The net area of any such opening or openings shall not exceed 0.05 square metre and in no case shall a gap under a door exceed 25 millimetres. The grille shall be capable of being manually closed from each side of the door.
(4) Every door in a “B” Class bulkhead which forms a stairway enclosure or part thereof shall be self-closing.
(5) Hold-back arrangements may be fitted to doors to which subregulation (4) refers provided that such arrangements—
(a) have remote release fittings of a type which in the event of disruption of the control system will automatically close the doors; and
(b) will permit each door to be closed manually.

120. Details of construction
(1) Where Method IC is adopted ceilings, linings, draught stops and their associated grounds in accommodation and service spaces and control stations shall be non-combustible.
(2) Where Method IIC or Method IIIC is adopted ceilings, linings, draught stops and their associated grounds in corridors and stairway enclosures serving accommodation and service spaces and control stations shall be non-combustible.

122. Miscellaneous items of fire protection
(1) Any pipe which penetrates an “A” Class division or “B” Class division shall be of suitable material having regard to the temperature such divisions are required to withstand.
(2) In accommodation spaces, service spaces or control stations pipes intended to convey oil or other flammable liquids shall be of a suitable material having regard to the risk of fire.
(3) Overboard scuppers, sanitary discharges or other outlets close to or below the waterline shall not be of a material likely to fail in the event of fire and thereby give rise to danger of flooding.
(4) Electric space heaters shall be fixed in position and shall be so constructed as to reduce the risk of fire to a minimum. No such heater shall be constructed with an element so exposed that clothing, curtains or other material can be scorched or set on fire by heat from the element.
(5) Cellulose-nitrate film shall not be used in cinematograph installations.
(6) All waste-paper receptacles shall be constructed of non-combustible materials with solid sides and bottoms.
(7) In spaces where penetration of oil products is possible, the exposed surface of insulation materials shall be impervious to oil or oil vapours.
(8) Every air space enclosed behind a ceiling, panel or lining within accommodation spaces, service spaces and control stations shall be divided by close fitting draught stops which shall be spaced not more than 14 metres apart and which shall be closed at each deck.

123. Fixed fire detection and fire alarm system, and automatic sprinkler, fire detection and fire alarm system
(1) In ships in which Method IC is adopted, a fixed fire detection and fire alarm system of an approved type complying with the requirements specified in Schedule 11 shall be so installed and arranged as to provide smoke detection and manually operated call points in all corridors, stairways and escape routes within accommodation spaces.
(2) In ships in which Method IIC is adopted, an automatic sprinkler, fire detection and fire alarm system of an approved type complying with the requirements specified in Schedule 7 shall be so installed and arranged as to protect accommodation spaces, galleys and other service spaces, except spaces which afford no substantial fire risk such as void spaces and sanitary spaces. In addition, a fixed fire detection and fire alarm system complying with the requirements specified in Schedule 11 shall be so installed and arranged as to provide smoke detection and manually operated call points in all corridors, stairways and escape routes within accommodation spaces.
(3) In ships in which Method IIIC is adopted, a fixed fire detection and fire alarm system of an approved type complying with the requirements specified in Schedule 11 shall be so installed and arranged as to detect the presence of fire in all accommodation spaces and service spaces, except spaces which afford no substantial fire risk such as void spaces and sanitary spaces. Notwithstanding the foregoing exception smoke detection and manually operated call points shall be installed in all corridors, stairways and escape routes.

124. Special arrangements in machinery spaces
The following provisions shall apply to machinery spaces—
(a) the number of openings to machinery spaces shall be the minimum compatible with the proper working of the ship;
(b) windows shall not be fitted in machinery space boundaries;
(c) any machinery space of Category A which is accessible from an adjacent shaft tunnel shall be provided with a light-weight steel fire-screen door in addition to any watertight door; the fire-screen door shall be operable from each side and shall be located at the shaft tunnel side of the bulkhead.
