The British Standards Institution (BSI) is the UK National Standards Body (NSB). It publishes standards and provides a range of books, self-assessment tools, conferences and training services. It also represents UK economic and social interests in European and international standards organisations.
BS 7974 Application of fire safety engineering principles to the design of buildings. Code of practice is aimed at fire safety engineers (FSE) and practitioners, and is also intended for:
- Members of the fire and rescue service.
- Structural engineers.
- Government agencies.
- Related industries such as insurers and systems engineers.
- PD 7974-1 Initiation and development of fire within the enclosure of origin.
- PD 7974-2 Spread of smoke and toxic gases within and beyond the enclosure of origin.
- PD 7974-3 Structural response and fire spread beyond the enclosure of origin.
- PD 7974-4 Detection of fire and activation of fire protection systems. NOTE: This document is no longer maintained since it has been incorporated into other documents, but it is referred to as part of the PD 7974 series for the sake of completeness.
- PD 7974-5 Fire and rescue service intervention.
- PD 7974-6 Occupant evacuation, behaviour and condition.
- PD 7974-7 Probabilistic risk assessment.
The practices included within the standard are applicable to all types of new construction and existing buildings. It is based on an approach to fire safety that focusses on the protection of people and property while showing sensitivity to the environment.
This analytical process is based on the concept of qualitative design review (QDR), which is a technique that allows fire safety engineers to consider the possible ways a fire hazard might arise and establish a range of strategies to maintain the risk at an acceptable level.
The process is broken down into three stages:
- Initial review. Objectives are defined, criteria are established and solutions are proposed.
- Analysis: Evaluations are made of solutions identified in the initial review.
- Assessment: The results of the analysis are measured against the criteria in the initial review.
