ATEX 2014/34/EU is a European Union directive that regulates equipment and protective systems intended for use in potentially explosive atmospheres. It aims to ensure that products are safe and reliable in environments where flammable gases, vapors, or dust may be present, thereby protecting workers and the environment. The directive outlines essential health and safety requirements for manufacturers, who must ensure their products are tested and certified before being placed on the market. Compliance with ATEX standards helps to minimize the risk of explosions and enhances safety in industries such as oil and gas, mining, and chemical processing.
