The basics of explosion protection
An explosion is the sudden chemical reaction of a flammable substance with oxygen with the simultaneous release of high energy. Flammable substances may be present in the form of gases, vapours, mists or dusts. An explosion can only take place,when three factors are present simultane-ously (fig. 1):
