NFPA 551 火灾风险评价指南
1.1 Scope. This guide is intended to provide assistance, primarily to authorities having jurisdiction (AHJs), in evaluating the appropriateness and execution of a fire risk assessment (FRA) for a given fire safety problem. While this guide primarily addresses regulatory officials, it also is intended for others who review FRAs, such as insurance company representatives and building owners.
Use NFPA 551 to approve or evaluate fire and life safety solutions based on fire risk assessments.
The application of fire risk assessment methods in developing fire and life safety solutions continues to increase. NFPA 551 Guide for the Evaluation of Fire Risk Assessments identifies various types of fire risk assessment methods and describes the properties these methods should possess.
