ATEX A Directive | AxFlow
Many workplaces may contain, or have activities that produce, explosive or potentially explosive atmospheres. Areas classified into zones 0, 1, 2 for gas-vapor-mist and 20, 21, 22 directove dust must be protected from effective sources of ignition. Employers must classify areas where hazardous explosive atmospheres may occur into zones.
HSE Explosives website What is an explosive atmosphere? Further information and guidance on the classification and zoning of areas where potentially explosive atmospheres may occur and the selection of equipment for use in those areas:.
It is his duty to judge where there is a risk of explosion and then divide areas into Zones accordingly. Zone 20 — A place in which an explosive atmosphere in the form of a xtex of combustible dust in air is present continuously, or for long periods or frequently.
There are taex categories of equipment ‘I’ for mining and ‘II’ for surface industries. Please help improve it or discuss these issues on the talk page.
ATEX and explosive atmospheres
As of Julyorganisations in the EU must follow the directives to protect employees from explosion risk in areas with an explosive atmosphere. The directive also covers components essential for the safe use and safety devices directly contributing to the safe use of the equipment in scope.
Once certified, the equipment is marked by the ‘EX’ symbol to identify it as such. The operator is responsible for the safety of his equipment. Views Read Edit View history. ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres: The installer must observe the installation requirements and select and install the equipment correctly for its intended use.
The requirements in DSEAR apply to most workplaces where a potentially explosive atmosphere may occur. Explosive atmospheres can be caused by flammable gases, mists or vapours or by combustible dusts.
It is only natural that the worldwide leading producer of air-operated, double-diaphragm pumps complies with the ATEX A directive for explosive atmospheres.

In DSEAR, an explosive atmosphere is defined as a mixture of 100a 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.
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. Effective ignition source is a term defined in the European ATEX directive as an event which, in combination with sufficient oxygen and fuel in gas, mist, vapour or dust form, can cause an explosion.
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. Manufactures of explosion protected apparatus are responsible for applicable testing, certification, and documentation and are required to ensure that each device manufactured complies with design tested.
Certification ensures that the equipment or protective system is fit for its intended purpose and that adequate information is supplied with it to ensure that it can be used safely. The technical dossier must be kept for a period of 10 years.
A – switch to normal size A – switch to large size A – switch to larger size. This article may be confusing or unclear to readers. Before a workplace containing zoned areas comes into operation for the first time, the employer must ensure that the overall explosion safety measures are confirmed verified as being safe. You can visit our cookie privacy page for more information.
Providing anti-static clothing Employers must provide workers who work in zoned areas with appropriate clothing that does not create the risk of an electrostatic discharge igniting the explosive atmosphere, eg anti-static footwear. Confirming verifying overall explosion safety Before a workplace containing zoned areas comes into operation for the first time, the employer must ensure that the overall explosion safety measures are confirmed verified as being safe.
If there is enough of the substance, mixed with air, then all it needs is a source of ignition to cause an explosion. 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: Preventing releases of dangerous substances, which can create explosive atmospheres, and preventing sources of ignition are two widely used ways of reducing the risk.
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. Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapours or by combustible dusts.
