FireTox Technical Director, Dr. Jamie McAllister, was recently appointed to the NFPA 921 committee. NFPA 921, Guide for Fire and Explosion Investigations details the scientific methodology and analyses used when conducting a fire origin and cause investigation. In 2000, the Department of Justice stated in "Fire and Arson Scene Evidence: A Guide to Public Safety Personnel" that NFPA 921 is the "benchmark for the training and expertise of everyone who purports to be an expert in origin and cause determination of fires." We are honored to contribute to the continual improvements of the NFPA 921 document and to scientific advancements in the field of fire and explosion investigation.
