The purpose of verifying the overall explosion safety is to confirm the workplace can operate safely in accordance with the ATEX User Directive and associated EU member state legislation such as DSEAR.

The aim of this verification is to identify the documentation, activities and inspections required prior to and during the commissioning of a plant, in order to verify the explosion safety of the plant in accordance with Reg 7(4) of DSEAR.


DSEAR Reg 7 applies to places where explosive atmospheres may occur.

Reg 7(4) states, Before a workplace containing places classified as hazardous pursuant to paragraph 1 (Requirement to Classify areas that are hazardous) is used for the first time, the employer shall ensure that its overall explosion safety is verified by a person who is competent in the field of explosion protection as a result of his experience or any professional training or both.
