Which National Fire Protection Association (NFPA) standard pertains to fire investigations?

The National Fire Protection Association (NFPA) standard that pertains to fire investigations is NFPA 921. This standard provides guidelines for the investigation of fire incidents, including methods for determining the origin and cause of fires. It outlines principles for conducting fire investigations, emphasizing systematic approaches and scientific principles to ensure thorough and accurate findings.

Understanding the importance of NFPA 921 is crucial for fire captains and investigators, as it equips them with the framework necessary to evaluate evidence effectively, document findings, and ultimately report on the incident. This standard serves as a valuable resource for maintaining credibility and ensuring that investigations are conducted with a high degree of professionalism and accuracy.

Each of the other options pertains to different areas of fire safety and prevention; for instance, NFPA 101 addresses life safety from fire in buildings and structures, NFPA 472 covers hazardous materials response, and NFPA 704 focuses on the identification of materials' hazards, rather than the investigative processes following a fire incident.
