Application of fire safety engineering principles to the design of buildings. Probabilistic risk assessment

This Published Document provides guidance on probabilistic risk analysis in support of BS 7974, Application of fire safety engineering principles to the design of buildings — Code of practice . It sets out the general principles and techniques of risk analysis that can be used in fire safety engineering. This Published Document also outlines the circumstances where this approach is appropriate and gives examples illustrating their use.

This Published Document also includes data for probabilistic risk assessment and criteria for assessment. The data included is based on fire statistics, building characteristics and reliability of fire protection systems. The criteria included cover life safety and property protection, both in absolute and comparative terms.

This Published Document does not contain guidance on techniques for hazard identification or qualitative risk analysis.

Probabilistic risk assessment of fire in buildings (with the exception of nuclear, chemical process, offshore and transport) is not widely used and so a discussion of possible future developments is included.
