ATEX and explosive atmospheres – Fire and explosion
This article has multiple issues. Background What is an explosive atmosphere? In DSEAR, an explosive atmosphere is defined as a mixture driective 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 and explosive atmospheres Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapours or by combustible dusts. The directive also covers components essential for the safe use and safety devices directly contributing to the safe use of the equipment in scope.
Zone 0 and 20 are the zones with the directove risk of an explosive atmosphere being present. EngvarB from July Use dmy dates from July Qtex articles needing reorganization from June Wikipedia articles needing clarification from June All Wikipedia articles needing clarification Wikipedia articles with style issues from April All articles with style issues Articles with multiple maintenance issues.
Please help us clarify the article. ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres:. Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapours or by combustible dusts.
Examples include places where work activities create or release flammable gases or vapours, such as vehicle paint spraying, or in workplaces handling fine organic dusts such as grain flour or wood. Skip to content Skip to navigation. Directuve in use before July is allowed to be used indefinitely provided a risk assessment shows it is safe to do so.
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. For more information on how the requirements of the Directive have been put into effect in Great Britain see the information in the section Explosive atmospheres in the workplace below. This standard given by the Occupational Safety and Health Administration defines and classifies hazardous locations such as explosive directiive.
Once certified, the equipment is marked by the ‘EX’ symbol to identify it as such. Retrieved from ” https: 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 directivf being safe. It is his duty to judge where there is a risk of explosion and then divide areas into Zones accordingly.
Employers must classify areas where hazardous explosive atmospheres may occur into zones. There are two categories of equipment ‘I’ for mining and ‘II’ for surface industries.

The ATEX directive consists of two EU directives describing what equipment and work space is allowed in an environment with an explosive atmosphere. 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.
These latter devices may be outside the potentially explosive environment. X pumps feature a proper and specific grounding point. Is this page useful? In addition to the general requirements, the Regulations place the following specific duties on employers with workplaces where explosive atmospheres may occur.
