The National Fire Protection Association publishes this manual which is the standard of care in fire investigation. This guide can be viewed for free on the NFPA website which is an excellent way to become familiar with the standards; however, if you wish to download or print it, you must purchase a copy. Email Sarah Rackley Olson if you would like to borrow a copy from the NCIDS Forensics Library or if you need a list of cases where this manual was accepted by courts as the standard of care. The Organization of Scientific Area Committees (OSAC) for Forensic Science approved the NFPA for inclusion in the OSAC Registry in 2016. The OSAC Registry serves as a trusted repository of high-quality, science-based standards and guidelines for forensic practice.
