Heat is necessary to begin the combustion process. Once started, fire produces its own heat. Wild land fires originate from such sources of heat as matches, embers from cigarettes, cigars or pipes, campfires, trash fires, exhaust sparks from railroad locomotives, sparks from brake shoes or �hot-box� on railroad cars.

Can hot air cause a fire?

Hot air will always rise and it will flow under the ceiling of a room spreading the heat from the fire. When a fire is burning large amounts of hot gases and smoke are produced. These will travel through the house in hot air currents often igniting more combustible materials causing the fire to spread.
