Topics: Accident Reconstruction
The manner in which a motor vehicle fire is initiated and subsequently spreads is dependent on a number of complex, interdependent, phenomena including combustion kinetics, heat transfer and fluid dynamics. Because the damage caused by a fire is coupled to these phenomena, damage patterns can sometimes be used to understand certain characteristics about the fire. In many cases, the goal is to determine the cause and origin of the fire.
In this highly interactive, hands-on course, participants will acquire a working knowledge of fire science and be able to use this knowledge to assess possible ignition mechanisms, evaluate burn patterns, and analyze fire spread. This seminar will also explore the interpretation and limitations of the physical evidence from a fire scene. The approach to collecting and retaining important physical evidence, and laboratory techniques to examine this evidence, will also be described. As an in-class project, participants will have the opportunity to inspect several burned vehicles, predict cause and origin and compare findings to the actual cause and origin of the fire, as shown in burn test videos.
By attending this seminar, you will be able to:
This seminar is designed for engineers, scientists, investigators and consultants involved in the investigation of vehicle fires.
An engineering degree in any discipline would be beneficial.

Dr. Jeff Colwell is Principal Engineer at Colwell Consulting LLC where he specializes in the engineering analysis of thermal and combustion processes, particularly the cause, origin and propagation of fires and explosions. Prior to starting his own consulting company, Dr. Cowell was the Principal Engineer in Exponent's Thermal Science practice where he specialized in the engineering analysis of thermal and combustion processes, especially the cause, origin, and propagation of fires and explosions. Dr. Colwell has particular expertise investigating fires associated with automobiles, recreation vehicles, motorcycles, and heavy trucks, where typical fire scenarios include post-collision fires, structure fires involving vehicles, and fires that occur while the vehicle is being operated. He analyzes how these fire scenarios, along with vehicle design, operation, maintenance, repair, and aftermarket equipment, are related to mechanisms of fire causation, growth rate, and spread. He has specialized expertise in designing and conducting both component and full-scale tests to evaluate these complex relationships. Prior to joining Exponent, Dr. Colwell held research positions at AlliedSignal Aerospace, the Combustion Laboratory at Arizona State University, the High Temperature Gas Dynamics Laboratory at Stanford University, and the Thermal Sciences and Propulsion Center at Purdue University. He has a B.S. in Mechanical Engineering from the University of Wyoming, a M.S. in Mechanical Engineering from Purdue University, a M.S. in Engineering from Stanford University and a Ph.D. in Mechanical Engineering from Arizona State University.
