A multi-disciplined forensic engineering and fire investigation company formed in 1970, combining origin-and-cause investigation with marine, mechanical, electrical, civil and materials engineering, industrial hygiene and a fully equipped chemical laboratory at its Columbus headquarters and research facility. Randy Watson — IAAI-CFI, IAAI-CI, CFEI, CVFI and CFII, and the firm’s Director of Technical Training — chairs the NFPA Technical Committee on Fire Investigations, the committee responsible for NFPA 921; Jason D. Wallace and Carl Dolente are also IAAI Certified Fire Investigators and NAFI CFEIs. Findings are offered as an aid to the trier of fact, not a substitute for it.
