What is a Zone 0 hazardous area?

What is a Zone 0 hazardous area?

Zone 0: An area in which an explosive gas atmosphere is present continuously or for long periods; Zone 2: An area in which an explosive gas atmosphere is not likely to occur in normal operation and, if it occurs, will only exist for a short time.

What is Zone 0 and give an example?

Examples include: places where the work creates or releases flammable gases or vapours (e.g. paint spraying) places handling fine organic dusts (e.g. grain storage and woodworking) underground mines (for dust) oil and gas (for vapour.

Can XD be used in Zone 0?

Our readers sent us numerous requests regarding the fact that “Ex d”, “Ex e”, “Ex p”, “Ex o”, “Ex q” equipment cannot be used in Zone 0.

What is ATEX electrical equipment?

The EU’s ATEX Directive defines essential health and safety requirements for equipment and protective systems used in potentially explosive atmospheres (“ATEX” is derived from the French “ATmosphere EXplosible).

What is ATEX Zone?

ATEX generally refers to the hazard of explosive atmospheres occurring in the workplace due to the presence of flammable gasses or combustible dust mixed in air, which can give rise to the risk of explosion.

Is ATEX Recognised in Australia?

‘ In Australia, equipment that is certified ATEX is not accepted as it is not up to the Australian standard. What is IECEx certification? The IECEx Scheme is an internationally-recognised regulation that demonstrates a business’s conformity with IEC Standards.

Which is better EXD or EXE?

Exe enclosures, also known as ‘increased safety’ enclosures, are typically the cheaper option, while Exd enclosures offer the additional safeguard of containing any flames. The final decision may be based on the characteristics of the surrounding atmosphere, including its temperature T-rating.

How do you classify ATEX zones?

In a hazardous dust environment, an ATEX Zone 21 is classified as an area that is classified ‘as a place in which an explosive atmosphere in the form of a cloud of combustible dust in the air is likely to occur occasionally during normal operation’ whereas an ATEX Zone 22 is classified as ‘a place in which an explosive …

How do you classify ATEX Zone?

What does Zone 0 mean on ATEX?

ATEX Zone 0. 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 persistence if it does.

What are the hazards in the ATEX Zone?

Presence of explosion hazards in the ATEX zone The more frequent an explosive gas or dust cloud is present, the more dangerous the zone. Therefore, always try to avoid or reduce the zone. A hazardous area classification is mandatory and written down in the Explosion Protection Document.

Is an ATEX Zone 2 air conditioner explosion proof?

An ATEX zone 2 air conditioner goes into category 3 explosion-proof equipment. For use in ATEX zone 1, category 2 explosion-proof equipment is required. Does this make sense? You probably don’t think so, but we promise you that there is an obvious explanation.

What is the best way to reduce ATEX Zone?

A measure, like specific ventilation, is often an effective and relatively inexpensive solution for zone reduction. We have experienced situations where ATEX zone 0 has been reduced back to ATEX zone 2 – just with the help of ventilation. In general, we see that 80% of all ATEX zones are set as a zone 2 or 22.
