What is ATEX

The ATEX directives refer to two European Directives describing the minimum safety requirements for equipment and workspaces in an explosive atmosphere. The directives are law in Europe since July 2003 and concerns both the Manufacturer and the Employer.

1) The ATEX “workplace” Directive 1999/92/EC concerns the classification of the explosive atmospheres into area classes based on the likelihood of an explosive atmosphere occurring and its persistence. The Directive details the minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres.

2) The ATEX Directive 2014/34/EU concerns equipment and protective systems intended for use in potentially explosive atmospheres. It creates a harmonized set of standards that unify the legislation of the EU member states.

The word ATEX derives from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosibles.

Classification of Hazardous Areas

Hazardous areas are evaluated and classified into zones (ATEX and IECEx) depending on the likelihood of a potentially explosive atmosphere being present.
