Our Fires and Explosions Group consist of Fire and Explosion Investigators supported by our Mechanical, Electrical, Chemical, Mining, and Material Engineers. These Certified Investigators and qualified Engineers have the credentials and experience to determine the origin and cause of structure, vehicle, and mine fires and explosions, including arson.
All investigations are conducted in accordance with the industry standard NFPA 921 (Guide for Fire and Explosion Investigations).  With or without a fire scene to examine, these experts analyze all available information to form origin and cause opinions, and provide expert reports and testimony, as required.
In addition to fires and explosions, these seasoned experts also conduct investigations involving carbon monoxide poisoning and asphyxiation.  Heating, cooling, cooking, ducting, and venting systems can be examined, analyzed and tested, including all controls and safety systems.
