NFPA 551 Guide for the Evaluation of Fire Risk Assessments

NFPA 551 Guide for the Evaluation of Fire Risk Assessments In the mid-1990s, it was recognized that the application of fire risk assessment methods in developing fire and life safety solutions continued to increase. However, a set of rules or a framework that described the properties of an acceptable fire risk assessment method was lacking. Additionally, there were no guidance documents available to those responsible for

approving or evaluating fire and life safety solutions that were based on a fire risk assessment. In response, NFPA established a new project and technical committee on fire risk assessment methods in 1999. NFPA 551, 2004 edition, was the first document prepared by the committee in response to the growing need for guidance documents on fire risk assessment methods.

The 2007 edition includes a number of enhancements, and new information on the subject. Certain terms have been revised for consistency with other documents that address performance-based design and fire risk assessment methods, and further guidance has been provided on applying risk-informed decision making for various fire safety goals, including the preservation of cultural resources. More detail on selecting fire scenarios; identifying and grouping representative challenging scenarios into clusters for conducting more effective consequence analysis; addressing uncertainty; and the impact of the changing effectiveness of fire protection equipment, features, programs, and procedures has been added. The capabilities of those conducting a fire risk assessment, the key factors to consider when conducting or reviewing a fire risk assessment, and the role of an operations and maintenance manual are addressed. An expanded discussion on the role of qualitative,
semiquantitative likelihood, semiquantitative consequence, and quantitative methods in a fire risk assessment and cost-benefit analysis is included, as is more detail on proper documentation and elements of a fire risk assessment, and the importance of using checklists that address both likelihood and consequence.
