ATEX and explosive atmospheres – Fire and explosion
HSE aims to reduce work-related death, injury and ill health. Zone 20 — A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods or frequently. The installer must observe the installation requirements and select and install the equipment correctly for its intended use.
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.
It is only natural that the worldwide leading producer of air-operated, double-diaphragm pumps complies with the ATEX A directive dorective explosive atmospheres. Schedule 2 of DSEAR contains descriptions of the various classifications of zones for gases and vapours and for dusts. Direcive help by editing the article to make improvements to the overall structure.
Preventing releases of dangerous substances, which can create explosive atmospheres, and preventing sources of ignition are two widely used ways of reducing the risk. This page does not deal with intentional explosives such as those used in demolition work or blasting in quarries.
These pages will tell you more about explosive atmospheres and ATEX: Where necessary, the entry virective to areas classified into zones must be marked with a specified ‘EX’ sign. In addition to the general requirements, the Regulations place the following specific duties on employers with workplaces where directice atmospheres may occur. Atmospheric conditions are commonly referred to as ambient temperatures and pressures.

Electrical engineering European Union directives Explosion protection Electrical safety Certification marks Natural gas safety Standards. This article may be in need of reorganization to comply with Wikipedia’s layout guidelines. As of Julyorganisations in the EU must follow the directives to protect employees from explosion risk in areas with an explosive atmosphere.
The equipment must be kept in a fit state by regular inspection and maintenance. Explosive atmospheres in the workplace Equipment and protective systems intended for use in explosive atmospheres Where can I find further information?
Equipment in use before July is allowed to be used indefinitely provided a risk assessment shows it is safe to do so. For more information on how the requirements of the Directive have been put into effect in Great Britain see the section on Equipment and protective systems intended for use in explosive atmospheres. Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapours or by combustible dusts.
The clothing provided depends on the level of risk identified in the risk assessment. The technical dossier must be kept for a period of 10 years.
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. This standard given by the Occupational Safety and Health Administration defines and classifies hazardous locations such as explosive atmospheres.
Equipment and protective systems intended to be used in zoned areas should be selected to meet the requirements of the Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations The directive covers a large range of equipment, potentially including equipment used on fixed offshore platforms, in petrochemical plants, mines, flour mills and other areas where a potentially explosive atmosphere may be present.
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:. Zone 0 — 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 present continuously or for long periods or frequently. This must be done by a person or organisation competent to consider the particular risks in the workplace, and the adequacy of the explosion control and other measures put in place.
A summary of those requirements can be found below. 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.
ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres: The ATEX directive consists of two EU directives describing what equipment and work space is allowed in an environment with an explosive atmosphere. June Learn how and when to remove this template message. Industrial or Mining Application; 2.
Explosive atmospheres can be caused by flammable gases, mists or vapours or by combustible dusts.

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. 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. In very broad terms, there are three preconditions for the directive to apply: Explosions can cause loss of life and serious injuries as well as significant damage.
