ATEX stands for "ATmosphères EXplosibles," which refers to European Union directives that govern equipment and protective systems used in environments where explosive atmospheres may occur. These directives ensure that products are designed and tested to prevent ignition sources in areas with flammable gases, vapors, or dust. The ATEX framework includes two main directives: ATEX 114 for equipment and ATEX 153 for workplace safety. Compliance with these regulations is essential for manufacturers and employers to ensure safety in industries such as oil and gas, chemical processing, and mining, where explosive atmospheres are a significant risk.
