Fire spread in cavities: model behaviour

Article Abstract:

A computer simulation has been used to model the behaviour of fire in ceiling voids. Smoke and gas are the greatest hazards from fires and the unseen spread of smoke in ceiling cavities is dangerous. UK Building Regulations demand barriers to prevent smoke spread in cavities and prescribe barriers at 20m intervals. However, there was doubt as to the relevance of barriers in suspended ceiling cavities over large rooms. A Fire Research Station simulation showed that smoke could travel quickly in a ceiling void but did not build up by the door until after the time needed to evacuate the room.

Fire insurers' objectives in the design of buildings

Article Abstract:

Fire insurers require buildings, their contents and equipment to be protected from fire. This implies measures in excess of those stipulated in the Building Regulations which are concerned with life safety. Insurers' requirements are detailed in the Loss Prevention Council Code of Practice for the Construction of Buildings and are based on the concept of compartmentalisation of buildings. Sprinkler systems and automatic fire detection are regarded as complementary to this approach.
