Blast Damage Resulting from Overpressure
The explosion of a dust or gas (either as a deflagration or a detonation) results in a reaction
front moving outward from the ignition source preceded by a shock wave or pressure front.
After the combustible material is consumed, the reaction front terminates, but the pressure
wave continues its outward movement. A blast wave is composed of the pressure wave and subsequent
wind. It is the blast wave that causes most of the damage.
