Directive 2014/34/EU (ATEX) lays down rules on the sale and putting into service of equipment and protective systems intended for use in potentially explosive atmospheres. It aims to ensure that products fulfil certain requirements to protect the health and safety of persons, workers and the protection of domestic animals and property. It applies to a wide range of products, including equipment used on fixed offshore oil and gas platforms, in petrochemical plants, mines, flourmills and other areas where a potentially explosive atmosphere may be present.
