What Is an Explosion?

Ex|plo|si|on; -s <lat.> (explosio) means "escaping under pressure." What happens during an explosion, which factors are important and what protective measures are available? You will learn everything you need to know about explosion protection right here.

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.
