14B.2.10 Details of construction

  14B.2.10.1 In accommodation and service spaces, control stations, corridors and stairways:

• .1 air spaces enclosed behind ceilings, panelling or linings should be suitably divided by close-fitting draught stops not more than 14m apart; and

• .2 in the vertical direction, enclosed air spaces, including those behind linings of stairways, trunks, etc. should be closed at each deck.

  14B.2.10.2 The draught stops are to be non-combustible and are to form a continuation above the ceiling of the bulkhead below or the other side of the panelling or lining to the bulkhead, as far as possible.

  14B.2.10.3 Where the structure or 'A' Class divisions are required to be insulated, it is to be ensured that the heat from a fire is not transmitted through the intersections and terminal points of the divisions or penetrations to uninsulated boundaries. Where the insulation installed does not achieve this, arrangements are to be made to prevent this heat transmission by insulating the horizontal and vertical boundaries or penetrations for a distance of 450mm.

  14B.2.10.4 Without impairing the efficiency of the fire protection, the construction of ceilings and bulkheads should allow a fire patrol to detect any smoke originating in concealed and inaccessible places, except where there is no risk of fire originating in such places.

  14B.2.10.5 When gaseous fuel is used for domestic purposes, the arrangements for the storage, distribution and utilisation of the fuel should be such that, having regard to the hazards of fire and explosion which the use of such fuel may entail, the safety of the vessel and the persons onboard are preserved.

In particular, open flame gas appliances provided for cooking, heating or any other purposes, should comply with the requirements of EC directive 90/396/EEC or equivalent and, the installation of open flame gas appliances should comply with the appropriate provisions of Section 14A.5.
