ATEX (Atmosphères Explosibles) refers to European Union directives for equipment and protective systems intended for use in potentially explosive atmospheres. The directives ensure equipment safety in explosive atmospheres, protect workers from explosion risks, harmonize European standards, and define equipment categories and zones.
There are two main directives: ATEX 114 (2014/34/EU) is the equipment directive for manufacturers, and ATEX 153 (1999/92/EC) is the workplace directive for employers. Both are essential for compliance in European installations.
Equipment for use in explosive atmospheres must be marked with CE marking, Ex symbol, equipment group (I for mining, II for surface), equipment category, explosion protection type, temperature class, and gas group. This marking ensures proper equipment selection and installation.
Zone classification includes Zone 0 (continuous explosive atmosphere), Zone 1 (likely explosive atmosphere), and Zone 2 (unlikely explosive atmosphere). Each zone requires different levels of protection and equipment certification.
Application to F&G systems is critical: gas detection transmitters must be ATEX certified, ensuring safe operation in hazardous areas. This is required for European installations and is critical for compliance with local regulations.
