We work closely with our clients when investigating a thermal event to uncover root cause and origin, evaluate component or material failures, and assess any human factors involved. Our team prioritizes scene integrity, safety, and evidence preservation from the outset, ensuring a thorough and efficient investigation.
We employ visual capture technology to meticulously document the scene and have a network of laboratories and facilities nationwide that are equipped to perform comprehensive artifact examinations, burn testing, explosion analyses, and product testing. We also use gas dispersion modeling, fire modeling, chemical analysis, and 3D computer modeling to understand the origin and development of thermal events.
Comprised of experienced engineers, fire and explosion investigators, and technologists, our team specializes in determining the origin and cause of various fire and explosion types to provide actionable insights and deliver professional reports, expert testimony, and clear, accurate visualizations for our clients.
