Description 

NFPA 921 is the field's leading reference for safe and systematic fire and explosion investigations.

Whether you're investigating a residential fire or a complex industrial disaster, the most important resource for fire investigators, litigators, and insurance professionals is NFPA 921: Guide for Fire and Explosion Investigations. This trusted Guide addresses every stage of a very complex process -- from basic fire investigation methodology to collecting evidence to failure analysis. Each edition is updated based on the most recent court cases, scientific data, and trends, to help you offer expert testimony and render opinions that stand up to scrutiny.

  • The 2011 edition of NFPA 921: Guide for Fire and Explosion Investigations has a rewritten Chapter 18 on cause that helps ensure fire investigators use scientific methodology when developing hypotheses, avoiding errors and Daubert challenges. An all-new section outlines the report review process in fire investigation and discusses peer vs. technical review. A critical update concerning explosion investigations features new illustrations and photos. Numerous other changes help users respond to growing and emerging fire problems, such as vehicle fires involving electric/hybrids and their potential for high voltage hazards impacting investigators.
  • The 2008 edition of NFPA 921: Guide for Fire and Explosion Investigations clarifies the process investigators should use to identify and recognize fire effects and fire patterns. Other changes present a more comprehensive, systems approach for dealing with complex incidents -- such as those involving fatalities or injuries, fires in high-rises or building complexes, and fires or explosions in industrial plants or commercial properties. A new chapter on marine fire investigations provides first-time coverage of fire and explosion investigations involving recreational boats, including safety issues due to environmental contaminants.
