ISO 8421-1, EN 1127-1 defines an explosion as “a sudden oxidation or decomposition reaction with increase of temperature, pressure or both at the same time.” This refers to a chemical reaction that with a simultaneous convergence of oxygen (air), a flammable material and a source of ignition in a particular ratio, causes temperature and pressure to increase abruptly. If the heat that arises cannot be discharged quickly enough, there is a sudden volume expansion of the concurrent gases and a release of great heat energy accompanied by a pressure wave: the explosion.
