What is NFPA 921 primarily designed for?

NFPA 921 is predominantly designed to provide a systematic framework for fire investigation. This framework is essential as it outlines methodologies and best practices for conducting thorough and objective fire investigations. By establishing a structured approach, NFPA 921 aids investigators in determining the origin and cause of fires, ensuring that the investigations are conducted legally and scientifically.

The standard emphasizes the importance of evidence collection, preservation, and analysis, which are critical for arriving at factual conclusions in fire investigations. It brings together various principles and practices to enhance the reliability of findings, thereby supporting the work of investigators in providing accurate reports for legal and insurance matters.

The focus on a systematic approach distinguishes NFPA 921 from other standards that may address qualifications or safety measures. While those topics are essential in their own right, NFPA 921 specifically targets the methodology and principles that enhance the investigative process itself.
