Explosions may occur for many reasons, accidentally or intentionally. Firefighters are generally somewhat familiar with explosions caused by the ignition of natural gas, propane, flammable liquids or vapors, dusts, and even backdraft. The regulated, controlled use of explosives is standard for construction, demolition, mining, and other industries. Fire training has often been limited to the type of explosions firefighters normally encounter and specifically to fire suppression techniques. Most firefighters and investigators have had less experience with intentionally set explosions and their effects.
