ATEX Zone 2, 22 Zone 2, 22 means that there is no hazardous material present, but if there is, it is for less than 10 hours a year and in low concentration. The hazardous area industry has been stuck in the past for decades by large manufacturing companies that wish their customers to believe there is no alternative to their long lead, heavy, very expensive and cumbersome Ex d flameproof.
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 EN60079-10-2:2009): 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.
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 20: a continuous presence of combustible dust. A high level of protection is required for both electrical and non-electrical elements. Two separate safety systems are required for each risk. Type testing and certification is required by a notified body. Zone 21: an occasional presence of combustible dust during normal operation. Elements.ATEX Zone 21 Definition - What is Zone 21? A Zone 21 area is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of powder or dust is likely to occur in normal operation occasionally. These are typically process areas where dusts and powders are more likely to be present. For Zone 21 applications, we use passive protection.
Zones. Hazardous areas are classified into zones based upon the frequency of the occurrence and duration of an explosive gas atmosphere. i.e. this is the probability of a fuel source being present and are critical to the risk assessment of a site and the site owner has a legal obligation to conduct a risk assessment and zone the site accordingly.

ATEX is a uniquely European Union directive for protection against explosive atmospheres. No. It’s not harmonized with NFPA combustible dust standards and not considered by OSHA an acceptable certification for electrical equipment used in hazardous locations. Read on for more details about ATEX certification and its relevance in the United.

Understanding ATEX Codes; If you’re working in an environment where there’s a risk of combustion, learning to understand ATEX codes applied to equipment is essential. By learning to interpret these codes you can determine whether the equipment is safe for use, ensuring protection at all times from ignition. We’ll begin by looking at a sample code that you might see on a piece of.
Zone 2: An area in which an explosive gas atmosphere is not likely to occur in normal operation, but if it does occur, it will exist for a short period only. Zone 20: An area in which an explosive dust atmosphere, in the form of a cloud of dust in air, is present continuously, or for long periods or frequently. Zone 21.
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.
