GexCon's team of licensed Certified Fire and Explosions Investigators (CFEI) and Professional Engineers (PE) have performed hundreds of fire origin and cause investigations, ranging from vehicle and residential fires to large scale fires and explosions at chemical processing, petrochemical and other industrial facilities.  GexCon engineers are knowledgeable on the application of fundamental scientific principles to fire origin and cause investigations, as specified in NFPA 921 (Guide for Fire and Explosion Investigations). 

Our team includes fire origin and cause experts, vehicle fire experts, fire and smoke modeling experts, ignition experts, thermal runaway and degradation experts, combustion science experts, dust and gas explosion experts.  We can mobilize and assist our clients on short notice, anywhere in the world; we provide forensic services in anticipation of litigation and in support of ongoing litigation, including expert reports and expert witness testimony.  Our expertise includes:

• residential and commercial fires
• electrical fires
• natural gas and propane fires
• industrial and residential gas-fired equipment (boilers, furnaces, thermal oxidizers, etc.)
• gas and vapor cloud explosions
• dust explosions and fires
• thermal runaway
• ignition mechanisms and combustion chemistry

Our staff has experience in designing and performing unique experiments to test fire origin and cause hypotheses.  In addition to traditional fire investigation, we routinely use innovative techniques such as 3D surveying methods, photogrammetry, video and image analysis, and three-dimensional computer animation to resolve and explain complex problems, as shown below.
