The principle of ATEX 1999/92/EC Directive is quite simple. Protect the worker from an explosion.

In Europe, EU legislation known as ATEX has been transposed into national laws under many different names.

There are 2 ATEX Directives, one (ATEX 1999/92/EC) relating to the company with potentially explosive atmospheres and the other (ATEX 2014/34/EU formerly 94/9/EC) to those supplying equipment to them.

ATEX 1999/92/EC - For industries that operate with potentially explosive atmospheres

ATEX 1999/92/EC requires companies to manage the risk and the process safely. This is known as DSEAR in the UK. Companies should:

  • Prevent the formation of explosive atmospheres in the workplace OR avoid the ignition of explosive atmospheres.
  • Conduct a hazardous area risk assessment including the likelihood of explosive atmospheres and a source of ignition
  • Classify the workplaces into hazardous area Zones depending on the frequency and time that an explosive atmosphere is present in the form of gas, vapour, powder or dust.For Example :
    • Zone 0 (highest risk gas/vapour)
    • Zone 1 (high risk gas/vapour)
    • Zone 2 (medium risk gas/vapour)
    • Zone 20 (highest risk powder/dust)
    • Zone 21 (high risk powder/dust)
    • Zone 22 (medium risk powder/dust)
  • Mark areas with signs at point of entry and train staff
  • Create and maintain an explosion protection document.
  • Select ATEX 2014/34/EU (formerly 94/9/EC) compliant equipment according to the intended Zones. Equipment such as fixed portable and transportable electrical and mechanical equipment.
