Application of fire safety engineering principles to the design of buildings. Probabilistic risk assessment | Status: Current

1 Scope This Published Document provides guidance on probabilistic risk analysis in support of BS 7974. It sets out the situations in which a probabilistic riskassessment can add value to traditional deterministic analyses and outlines acceptance criteria for the assessment. Furthermore, common analysis techniques of probabilistic riskassessment are summarily discussed. This Published Document also includes data for probabilistic riskassessment based on fire statistics, building characteristics and reliability of fire protection systems. This Published Document does not contain guidance on techniques for hazard identification or qualitative risk analysis.
