What is the main purpose of the NFPA 921 document?

The main purpose of the NFPA 921 document is to provide comprehensive guidelines for fire and explosion investigations. This guide outlines the best practices for investigators to follow in order to ensure thorough and scientifically sound analyses of fire scenes. It emphasizes the importance of systematic approaches to evidence collection, analysis, and reporting, which are critical for determining the origins and causes of fires. By adhering to these guidelines, investigators can enhance the reliability and credibility of their findings, which is essential in legal contexts and for improving fire safety practices.

While aspects such as financial evaluations, certification processes, and educational programs are important to the broader context of fire safety and investigation, they are not the primary focus of NFPA 921. The emphasis remains rooted in investigation methodologies that ensure accurate and effective outcomes when assessing fire and explosion incidents.
