Vehicle fire investigations require specialized training to correctly determine the origin and cause of the fire. A vehicle is packed with a variety of combustible materials, both under the hood and in the occupant compartment. This leads to rapid spread of a fire which can make isolation of the origin difficult.

A "self-extinguishing" belt, in general terms, refers to one that does not propagate a fire once the ignition source is removed in a controlled laboratory setting. Fire-safety standards for conveyor belting are similar among major coal mining countries, including Australia, Canada, China, Germany, India, Indonesia, Poland, Russia, and South Africa.
