BASICS EXPLOSION PROTECTION What are the Causes for an Explosion Classification of Zones for Dusts: Basically there are three factors that must be encountered when creating a potentially explosive area. Presence of oxygen, an explosive medium and an ignition source. The absence or avoidance of one of the three factors prevents an explosion. Zone 20 A dangerous, explosive atmosphere in the form of a cloud of combustible dust is constantly, for long periods or frequently present. Primary Explosion Protection Measures which prevent or limit the formation of a potentially explosive atmosphere...
