11 Restricted use of combustible material (R 34)
NEW CLASS B, C AND D SHIPS:
.1Except in cargo spaces, mail rooms, baggage rooms, or refrigerated compartments of service spaces, all linings, grounds, draughtstops, ceilings, and insulations shall be of non-combustible materials. Partial bulkheads or decks used to subdivide a space for utility or artistic treatment shall also be of non-combustible material.
.2Vapour barriers and adhesives used in conjunction with insulation, as well as insulation of pipe fittings, for cold service systems need not be non-combustible, but they shall be kept to the minimum quantity practicable and their exposed surfaces shall have qualities of resistance to the propagation of flame in accordance with the test procedure of IMO Resolution A.653(16).
CLASS B, C AND D SHIPS CONSTRUCTED ON OR AFTER 1 JANUARY 2003:
Instead of .2 the following paragraph .2a shall apply:
Vapour barriers and adhesives used in conjunction with insulation, as well as insulation of pipe fittings for cold service systems need not be non-combustible, but they shall be kept to the minimum quantity practicable and their exposed surfaces shall have low flame spread characteristics.
.3The following surfaces shall have low flame-spread characteristics:
exposed surfaces in corridors and stairway enclosures, and of bulkheads, wall and ceiling linings in all accommodation and service spaces and control stations;
concealed or inaccessible spaces in accommodation, service spaces and control stations.
.4The total volume of combustible facings, mouldings, decorations and veneers in any accommodation and service space shall not exceed a volume equivalent to 2,5 mm veneer on the combined area of the walls and ceilings. Furniture fixed to linings, bulkheads or decks need not be included in the calculation of the total volume of combustible materials.
In the case of ships fitted with an automatic sprinkler system complying with the provisions of Regulation II 2-A/8, the above volume may include some combustible material used for erection of “C” class divisions.
.5Veneers used on surfaces and linings covered by the requirements of paragraph .3 shall have a calorific value not exceeding 45 MJ/m2 of the area for the thickness used.
.6Furniture in stairway enclosures shall be limited to seating. It shall be fixed, limited to six seats on each deck in each stairway enclosure, be of restricted fire risk, and shall not restrict the passenger escape route. The Administration of the flag State may permit additional seating in the main reception area within a stairway enclosure if it is fixed, non-combustible and does not restrict the passenger escape route. Furniture shall not be permitted in passenger and crew corridors forming escape routes in cabin areas. In addition to the above, lockers of non-combustible material, providing storage for safety equipment required by Regulations, may be permitted. Drinking water dispensers and ice cube machines may be permitted in corridors provided they are fixed and do not restrict the width of the escape routes. This applies as well to decorative flower or plant arrangements, statues or other objects of art such as paintings and tapestries in corridors and stairways.
.7Paints, varnishes and other finishes used on exposed interior surfaces shall not be capable of producing excessive quantities of smoke and toxic products.
CLASS B, C AND D SHIPS CONSTRUCTED ON OR AFTER 1 JANUARY 2003:
Instead of .7 the following paragraph .7a. shall apply:
Paints, varnishes and other finishes used on exposed interior surfaces shall not be capable of producing excessive quantities of smoke and toxic products, this being determined in accordance with the IMO Fire Test Procedures Code.
Primary deck coverings, if applied within accommodation and service spaces and control stations, shall be of approved material which will not readily ignite, in accordance with the fire test procedures of IMO Resolution A.687(17) or give rise to toxic or explosive hazards at elevated temperatures.
CLASS B, C AND D SHIPS CONSTRUCTED ON OR AFTER 1 JANUARY 2003:
Instead of paragraph .8 the following paragraph .8a shall apply:
Primary deck coverings, if applied within accommodation and service spaces and control stations, shall be of an approved material which will not readily ignite or give rise to toxic or explosive hazards at elevated temperatures, this being determined in accordance with the IMO Fire Test Procedure Code.
