Zone 21 Area in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur, occasionally, in normal operation. Zone 22 Area 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.

This EX-4DCL Intrinsically Safe LED Safety Handlamp is ATEX Directive certified for safe use in hazardous locations in zones 1, 2 and zones 21, 22. This Application is widely used as mobile lighting in the Petrochemical and Offshore Industries, Fire-Fighting, Gas and Water Distribution and some other flammable and explosive locations.
ATEX Zones 21 and 22 are specific to hazardous dust environments, like can be found in the food industry in, for example, a flour mill where explosible dusts are often present. Some examples of explosible dusts within the food industry alongside flour are custard powder, instant coffee, sugar, dried milk, potato powder and soup powder as a solid substance that is finely ground may ignite more.Zone 21 Primary grade of release gives rise to Zone 21 - a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is likely to occur occasionally in normal operation. For example, bagging points and inspection ports that are frequently opened. Zone 22.Zone 20: Dust cloud likely to be present continuously or for long periods: Zone 21: Dust cloud likely to be present occasionally in normal operation: Zone 22: Dust cloud unlikely to occur in normal operation, but if it does, will only exist for a short period.
MENZEL offers a wide range of increased safety motors for Zone 2 (Ex ec) and dust ignition proof motors for Zone 22 (Ex tc). Our Ex ec and Ex tc motors are tailor-made with low, medium or high voltage, and are ideally suited for particularly demanding uses and applications. They are available not only with squirrel cage rotors, but also as special designs with slip ring motors. MENZEL.
Zone Hazardous Location 33 Introduction A major safety concern in industrial plants is the occurrence of fires and explosions. No other aspect of industrial safety receives more attention in the form of codes, standards, technical papers, and engineering design.
Da equipment can be installed in zone 20, 21, 22 Db equipment can be installed in zone 21, 22 Dc equipment can be installed in zone 22 Where a risk assessment is carried out to assess consequences, Gb can be installed in zone 0, and Gc can be installed in zone 1.
Zone 20—An area where combustible dusts or ignitable fibers and flyings are present continuously or for long periods of time. b. Zone 21—An area where combustible dusts or ignitable fibers and flyings are likely to occur under normal operating conditions.
The Scala XI Ear Defenders in conjunction with the Nexus safety helmet can be used in explosive atmospheres as it provides anti static protection according to IEC 60079-32-2:2015 Electrostatics hazards tests.

ATEX Classifications Glossary for products used in Explosive Atmospheres Explanations for product markings found on ATEX approved equipment. ATEX is the regulatory directive for the design, installation and use of products in environments where there is a potential explosion risk from flammable gases or dust that are or could be present in the surrounding air.
Zone 21 - an area in which a combustible dust, as a cloud, is likely to occur during normal operations in sufficient quantities to produce an explosive mixture. Zone 22 - an area in which combustible dust clouds may occur infrequently and persist for only short periods of time or in which accumulations or layers may be present under abnormal conditions. Class III Locations Class III locations.
