Fire & Explosion Investigations

Industry Analysis

Addressing Safety Gaps in High-Rise Façade Fires

How do we help organizations discover root causes and build more resiliency to protect against fires and explosions?

Ģ��tv leverages more than 50 years of experience in fire investigations to conduct rigorous root cause analysis of fires and explosions while also helping clients develop proactive fire prevention strategies.

Our teams are mobility equipped and can deploy to most incident sites to perform a wide array of fire investigation services including fire origin analysis, debris field mapping, three-dimensional scanning, explosion damage assessment, and facility inspection for potential fire and explosion hazards.

Ģ��tv's multidisciplinary teams use advanced modeling tools including Computational Fluid Dynamics (CFD), Fire Dynamics Simulator (FDS), and Consolidated Model of Fire and Smoke Transport (CFAST), to evaluate explosions, wildfires, deflagrations, dust explosions, and heavy equipment fires. Our state-of-the-art testing facilities and laboratory research centers conduct rigorous analysis to provide answers for the most complex thermal-related incidents.

Our experts also provide expert testimony in litigation and arbitration cases using visual data demonstrations and computational flow models to demonstrate how fires progress, how flammable vapors disperse, and explosions propagate.

Capabilities and Services

Fire dynamics modeling is crucial to understanding how heat and smoke move throughout a building or area, such as during a wildfire. Our fire modeling capabilities are frequently used to support fire cause and origin investigations. Ģ��tv uses the Fire Dynamics Simulator (FDS) and the Consolidated Model of Fire and Smoke Transport (CFAST), which are developed and distributed by the National Institute of Standards and Technology (NIST).
To mitigate the risks of industrial explosions and fires due to combustible dust particles and finely divided powders, several National Fire Protection Association (NFPA) standards on combustible dust require industrial facilities to complete a dust hazard analysis (DHA) every five years and to complete a new DHA before implementing a new process or expanding a facility. Ģ��tv helps stakeholders identify equipment and processes that pose dust hazards and implement corrective actions to reduce the risk of combustible dust explosions.

For more than 50 years, Ģ��tv's engineers and scientists have investigated several thousand separate explosions that have involved a wide range of solid, liquid, and gaseous fuels. A wide range of industries — petroleum and chemical, defense and aerospace, oil and gas utilities, insurers, and law firms — call on us when they need to understand why and how an explosion occurred, the strength of the explosion, and how to prevent a similar event.
Our team has investigated thousands of fires involving countless products and applications. Ģ��tv engineers specialize in fluid flow evaluations, such as smoke and plume propagation modeling. In addition to traditional fire investigation tools, we use innovative techniques such as 3D surveying methods, photogrammetry, video and image analysis, and three-dimensional computer animation. At our Phoenix Test and Engineering Center (TEC), our experts perform large-scale fire and explosion testing.
The investigation of heavy equipment fires — such as farm equipment or construction vehicles — requires experience with the many systems involved. Ģ��tv provides the rigorous scientific expertise, conducting field inspections, laboratory testing, and technical analysis of hydraulic systems, bearing performance and failure, debris accumulation, electrical system performance and distribution, mechanical systems, and more.
Ģ��tv engineers provide a wide range of services associated with the investigation and prevention of fires associated with automobiles, motorcycles, buses, heavy trucks, recreational vehicles, and heavy equipment. Ģ��tv engineers currently serve in multiple organizations associated with motor vehicle fire safety, including the Society of Automotive Engineers (SAE) Fire Safety Committee and the National Fire Protection Association's (NFPA) Technical Committee responsible for NFPA 1192-Recreational Vehicles.
Wildland fires cause enormous damage every year in the United States. Ģ��tv's multidisciplinary teams of thermal engineers, environmental scientists, and arson investigators provide comprehensive, on-site fire investigations, analyze burn damage, and use cutting-edge research tools and technology to define the origin, determine the fire's path, and demonstrate emissions dispersion. Our civil engineering and environmental practices assist in the detailed surveys of area of origin, conduct aerial surveys of the burn damage, and GIS data for computer simulations. Our ecological practice can assist in the assessment of damage and consult on rehabilitation of the burned areas.
