| ATEX Telephone / Eex Telephone / Ex Tele |
The ATEX directive consists of two EU (European Union) directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere. ATEX derives its name from the French title of the 94/9/EC directive: "Appareils destinés à être utilisés en ATmosphères EXplosibles". As of July 2006, organisations in EU must follow the directives to protect employees from explosion risk in areas with an explosive atmosphere. Employers must classify areas where hazardous explosive atmospheres may occur into zones. 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. The aim of directive 94/9/EC is to allow the free trade of ‘ATEX’ equipment and protective systems within the EU by removing the need for separate testing and documentation for each member state. See the ATEX Directive for further information. |
