It is the owner/operators responsibility to determine the risk of possible explosion in his premises and a risk assessment must be carried out to allow him to declare his zones under ATEX directive 1999/92/EC, to comply with DSEAR regulations. ATEX. The ATEX directive uses zones to classify potentially explosive gas and dust atmospheres. Classifications range from an ignitable condition being an unlikely occurrence (Zones 2 and 22) to continuously present (Zones 0 and 20). > Gas / Vapour / Mist: Zone 0, Zone 1, Zone 2 > Powder / Dust: Zone 20, Zone 21, Zone … Zone classification ATEX classification required for equipment (for Group II, above-ground industry) Zone 0 (gas) Zone 20 (dust) PERMANENT RISK.

Within Europe, when electronic or electrical equipment of any kind is intended for use in a potentially hazardous area, the equipment must be ATEX-certified – per the EU directive 2014/34, which is more commonly known as the ATEX 114 directive (derived from Se hela listan på assured-systems.com The process is strongly influencing the ATEX zoning. For example if a process is designed to have powder tipped to a hopper without dust aspiration, the area around the tipping is likely to be classified zone 21, while if a dust aspiration system is present, dust around the tipping will be much more rare, only present when the dust aspiration system is defective or if the operator drops a bag Regarding ATEX 99/92/EC Directive, the requirement is that Employers must classify areas where potentially explosive atmospheres may occur, into zones. The classification given to a particular zone, and its size and location, depends on the likelihood of an explosive atmosphere occurring and its persistence if it does.
