14B.2.11 Restricted use of combustible materials

  14B.2.11.1 Except in spaces protected by an automatic sprinkler system and fully addressable fire detection system in accordance with 14B.2.14, all linings, grounds, and ceilings should be of non-combustible materials.

  14B.2.11.2 The use of combustible materials is to be kept to a minimum. Insulation materials should be non-combustible.

  14B.2.11.3 The following surfaces should be low flame spread:

• .1 exposed surfaces in corridors and stairway enclosures, and of bulkheads, wall and ceiling linings in all service spaces and control stations; and

• .2 concealed or inaccessible spaces in accommodation, service spaces and control stations.

As an alternative to .1 and .2 above, these spaces may contain surfaces that are not low flame spread, provided

• .3 adequate barriers of low flame spread surfaces are arranged to restrict the spread of flame areas at distances not greater than 5m, or

• .4 these spaces are protected by an automatic sprinkler system and fully addressable fire detection system in accordance with 14B.2.14.

  14B.2.11.4 Pipes penetrating 'A' or 'B' Class divisions are to be of approved materials having regard to the temperature such divisions are required to withstand.

  14B.2.11.5 Pipes conveying oil or combustible liquids through accommodation and service spaces are to be of approved materials having regard to the fire risk.

  14B.2.11.6 Materials readily rendered ineffective by heat are not to be used for overboard scuppers, sanitary discharges, and other outlets which are close to the waterline and where the failure of the material in the event of fire would give rise to the danger of flooding.

  14B.2.11.7 Furniture in the corridors and escape routes should be of a type and quantity not likely to obstruct access. Additionally, furniture along escape routes should be secured in place to prevent shifting if the vessel rolls or lists.

  14B.2.11.8 Primary deck coverings within accommodation spaces, service spaces and control stations are to be of a type which will not readily ignite, or give rise to toxic or explosive hazards at elevated temperatures. Reference is also to be made to the IMO FTP Code, Annex 1, Parts 2 and 6.

  14B.2.11.9 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 should be kept to the minimum quantity practicable and their exposed surfaces should have low flame spread characteristics.

  14B.2.11.10 Except when a fully addressable fire detection system is fitted, upholstery composites (fabric in association with any backing or padding material) used throughout the vessel should be approved in accordance with the IMO FTP Code, Annex 1, Part 8 or an equivalent standard acceptable to the Administration.

  14B.2.11.11 Except when a fully addressable fire detection system is fitted bedding components should be approved in accordance with the IMO FTP Code, Annex 1, Part 9 or an equivalent standard acceptable to the Administration.

  14B.2.11.12 Except when a fully addressable fire detection system is fitted, suspended textile materials such as curtains and drapes should be approved in accordance with the IMO FTP Code, Annex 1, Part 7, or an equivalent standard acceptable to the Administration.

  14B.2.11.13 Upholstery, bedding components and suspended textiles required to comply with the IMO FTP code or an equivalent standard are to be clearly labelled by the manufacturer stating the standard that they meet and any washing or cleaning instructions needed to maintain their fire resistance. These labels are not to be removed.

  14B.2.11.14 In spaces where penetration of oil products is possible, the surface of insulation is to be impervious to oil or oil vapours. Insulation boundaries are to be arranged to avoid immersion in oil spillages so far as is practicable.
