A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only (from 0,1hrs to 10hrs/365d).
ATEX Zone 21 – Category 2D explosion proof conversion guarantees an electrical and mechanical protection eliminating any explosion risk.
Maximum surface temperature T200° C, T135° C, T100° C
Installation and conversion of components suitable for use in the operating zone

Hazardous Gas, Vapour and Mist Environments: ATEX Zones 1 and 2
A Text 2 21 Niv
A good example of an ATEX Zone 1 or ATEX Zone 2 classified operation would be a chemical or petrochemical plant, where there is a heightened risk for explosion during the course of normal day to day operations. Within a hazardous gas environment an explosion can take place if a flammable substance, an oxidiser and a source of ignition are found simultaneously within the atmospheric air. The absence of any one of these three elements would stop an explosion from occurring, and that is why through continued innovation and increased focus on safety the lifting equipment industry is able to offer a broad range of explosion proof and spark proof hoists, winches and trolleys, etc. specifically for safe use in these hazardous environments.

Zone 1 is an area that is classified ‘as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapours and mists is likely to occur occasionally during normal operation’, whereas Zone 2 is an area that is classified ‘as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapours and mists is not likely to occur in normal operation but if it does occur, it will be present for a short period of time only’.
