(3) EXPLOSION. A rapid, sudden and violent expansion of air or relinquishment of energy with resultant pressures that are capable of producing destructive effects on contiguous objects or of destroying life or limb. “Explosion” includes, but is not limited to, a sudden and rapid combustion, causing violent expansion of the air, or the sudden bursting or breaking up or in pieces from an internal or other force. “Explosion” is not limited to cases caused by combustion or fire, but it may result from decomposition or chemical action.
