The assessment of explosion hazard – ATEX Users (ATEX 137) directive


Whenever risk of explosion occurs (due to workplaces, appliances or substances/mixtures involved in process specifications), a complex Risk Assessment – the assessment of explosion hazard should be performed.

Working installation, substances and mixtures employed, the ongoing processes and its mutual impact, probability of the explosive atmospheres and effective sources of ignition occurrence, the expected side effects – all should be taken into account.

The result of the assessment of explosion hazard form the basis of a decision on which particular solution of explosion protection should be employed. Following aims should be considered before employing a particular solution:

  1. avoiding or limiting the possibility of creating explosive atmospheres,
  2. avoiding or limiting the possibility of explosive atmospheres ignition,
  3. avoiding harmful side effects of explosions and counteract its spread.
