The ATEX directive uses zones to classify the potential for explosion in a given environment. For example, Zone 1 and Zone 2 both relate to an explosive atmosphere formed by the presence of the key elements needed for an explosion. These are a flammable substance (such as a gas, vapor or mist), coupled with an oxidizer and a source of ignition.ATEX zones for dusts Dust clouds in the explosive region (above the minimum explosible concentration) are categorised into 3 zones, based upon the grade of release (as per EN6:2009): Zone 20 Continuous release inside a dust containment enclosure gives rise to Zone 20 - a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is present continuously ...
