Areas classified into zones 0, 1, 2 for gas-vapor-mist and 20, 21, 22 for dust must be protected from effective sources of ignition. This article may be confusing or unclear to readers. Further information and guidance on the classification and zoning of areas where potentially explosive atmospheres may occur and the selection of equipment for use dirsctive those areas:. He must ensure that the equipment is installed in accordance with regulations and is tested before initial use.

The requirements in DSEAR apply to most workplaces where a potentially explosive atmosphere may occur. The equipment must be kept in a fit state by regular inspection and maintenance.

ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres: Please help by editing the article to make improvements to the overall structure. Zone 2 — A place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapour or mist is not likely to occur in normal operation but, if digective does occur, will persist for a short period only.

Classification of areas where explosive atmospheres may occur Employers must classify areas where hazardous explosive atmospheres may occur into zones. Where can explosive atmospheres be found? The clothing provided depends on the level of risk identified in the risk assessment.

These pages will tell you more about explosive atmospheres and ATEX: These latter devices may be outside the potentially explosive environment. Using the correct equipment can help greatly in this. Explosions can cause loss of life and serious injuries as well as significant damage.


In very broad terms, there are three preconditions for the directive to apply: Please help improve it or discuss these issues on the talk page. X pumps feature a proper and specific grounding point.

We are Europe’s leading source of pumps and pump expertise for the process industry and we intend to maintain that position by working fluidly, and ceaselessly, to bring you the best. Identifying areas where explosive atmospheres may occur Where necessary, the entry points to areas classified into zones must be marked with a specified ‘EX’ sign.

Some industry sectors and work activities are exempted because there is other legislation that fulfils the requirements.

Skip to content Skip to navigation. Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapours or by combustible dusts.

ATEX 100A Directive

There are four ATEX classification to ensure that a specific piece of equipment or protective system is appropriate and can be safely used in a particular application: Zone 0 and 20 require Category 1 marked equipment, zone 1 and 21 require Category 2 marked equipment and zone 2 and 22 require Category 3 marked equipment. Once certified, the equipment is marked by the ‘EX’ symbol to identify it as such.

This article’s tone or style may not reflect the encyclopedic tone used on Wikipedia. The technical dossier must be kept for a period of 10 years. Please help us clarify the article. In DSEAR, an explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture.

Preventing releases of dangerous substances, which can create explosive atmospheres, and preventing sources of ignition are two widely used ways of reducing the risk. In addition to the general requirements, the Regulations place the following specific duties on employers with workplaces where explosive atmospheres may occur. 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.


Zone 0 and 20 are the zones with the highest risk of an explosive atmosphere being present. Where necessary, the entry points to areas classified into zones must be marked with a specified ‘EX’ sign.

Atdx is only natural that the worldwide leading producer of air-operated, double-diaphragm pumps complies with the ATEX A directive for explosive atmospheres. Atmospheric conditions are commonly referred to as ambient temperatures and pressures.

Manufactures of explosion protected apparatus are responsible for applicable testing, certification, and documentation and are required to atexx that each device manufactured complies with design tested. Methane, hydrogen or coal dust are examples of possible fuels.
