    Training Burns 

    I have participated in the organized controlled burning of many more than 50 buildings and vehicles for fire investigative and firefighting training. During many of these training burns I have acted as instructor or assistant instructor of fire/arson/explosions investigation. We ignited or caused the ignition of buildings, objects and vehicles in many different ways to observe the effects of: ignition, fire behavior, ventilation, fuel package arrangement and geometry, explosions, fire environments and the various effects of the fire control and overhaul efforts have on the fire behavior and relative evidence. 

    Publications
