This report summarizes a program which defined the conditions under which motor vehicle crash fires are ignited and proposed practicable countermeasures to reduce the incidence of these fires. Both ignition sources and fuel spillage were investigated. Electrical sparks generated from damage to the vehicle's electrical system during a crash are studied as the most hazardous ignition sources. Vehicle headlight filaments are also ignition sources. Full-scale crash tests demonstrated how commercially available inertia switches will shut off the vehicle's electrical system during frontal, front-to-rear, and rollover crashes.
