Application of fire safety engineering principles to the design of buildings. Code of practice

| BSI | 2019 | 68 |
This British Standard provides a framework for an engineering approach to fire safety in buildings by giving recommendations and guidance on the application of scientific and engineering principles to the protection of people, property and the environment from fire. It is applicable to the design of new buildings and the appraisal of existing buildings.
The general approach to fire safety engineering (FSE) described in this British Standard can be applied to all types and uses of buildings or to facilities such as tunnels and process plants. However, the risks associated with installations used for the bulk processing of explosives or flammable liquids and gases necessitate special consideration which is beyond the scope of BS 7974 and its supporting documents.
