ATEX Zone 22. ATEX Zone 22 is an area where 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. ATEX Zone 21.
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.
ATEX Zone 0 and ATEX Zone 20 represent the most dangerous workplace environments. ATEX uses Zone numbers to distinguish between environments with different levels of danger. It is an employer’s responsibility to correctly classify the workplaces for which they are responsible. The classification given to a zone depends on the likelihood of an explosive atmosphere occurring and its.The ATEX directive distinguishes between two types of explosive atmospheres: gas and dust. Areas within these two kinds of explosive atmospheres are each divided into three sub-zones. Although the zones characteristics are identical for both gas and dust, their numbering is different. Zone 0, 1 and 2 refer to gas and Zone 20, 21 and 22 refer to.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.
Lately, we’ve seen more vacuum cleaners being marketed in the United States as “ATEX certified” or “ATEX approved.” We even offer some combustible dust safe pneumatic vacuums that meet ATEX requirements. However, the introduction of yet another acronym to the already crowded arena of OSHA, NFPA, NEC, and so on has understandably brought with it some confusion.

Miretti systems are designed in collaboration with leading OEM.
Zone 21 - A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally. Zone 21 - A place in which an explosive atmosphere in the form or 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.
Our products are suitable for use in many sectors that have a need for ATEX, IECEx and UL913 certified products for Zone 1, Zone 21, Zone 2 or Zone 22 and even include underground mining certification standards to enable us to provide products certified for use in almost every country in the world.
Classification of ATEX zones.

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 dust: Zone 20 (dusts): an area in which an explosive mixture is continuously present or present for long periods. Zone 21. Zone 22 (dusts): an area in which an explosive mixture is not likely to occur in normal operation and if it occurs it will exist only for a short time. The Axair team have undertaken extensive training in ATEX regulations but have a duty of care to ensure.
In general, we see that 80% of all ATEX zones are set as a zone 2 or 22. In practice: ATEX zone reduction. The extent of the impact of explosion-reducing measures is shown in the example below. Figure 1: Situation before implementation of safety measures. Mostly purple (ATEX zone 1) and red (ATEX zone 0).

The Atex zone classification system took effect in 2003 as a method of identifying products suited for use in areas with explosive atmosphere. It is a European classification system used primarily by the nations of the European Union. The Atex classification system is similar to the Class and Division ratings frequently seen on products in the United States.
First of all, Zone 2 certified equipment is not allowed to be carried through a Zone 1 environment, not even when the Zone 2 equipment is powered off. Secondly, if there is an emergency, all zones are automatically upgraded to a Zone 1, immediately making all Zone 2 equipment in violation with the guidelines. Thirdly, mobile devices are often carried around by users that might be unaware of.
