ATEX is the name commonly given to the two European directives for controlling explosive atmospheres. ATEX lifting equipment can mean electric chain hoists, wire rope hoists, and belt hoists, winches, trolleys, and pneumatic lifting equipment, and can be referred to as spark-proof or Ex equipment.

  1. Directive 99/92/EC (also known as ‘ATEX 137’ or the ‘ATEX Workplace Directive’) on minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.
  2. Directive 94/9/EC (also known as ‘ATEX 95’ or ‘the ATEX Equipment Directive) on the approximation of the laws of Members States concerning equipment and protective systems intended for use in potentially explosive atmospheres.

Zone 1
An area that is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapours and mists is likely to occur occasionally during normal operation.

Zone 2
An area that is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapours and mists is not likely to occur in normal operation but if it does occur, it will be present for a short period of time only.

Zone 20
Continuous release inside a dust containment enclosure gives rise to Zone 20 – a place in which an explosive atmosphere, in the form of a cloud of combustible dust in the air, is present continuously, or for long periods or frequently for short periods. For example, a mill or pneumatic conveying system.

Zone 21
Primary grade of release gives rise to Zone 21 – a place in which an explosive atmosphere, in the form of a cloud of combustible dust in the air, is likely to occur occasionally in normal operation. For example, bagging points and inspection ports that are frequently opened.

Zone 22
Secondary grade of release gives rise to Zone 22 – a place in which an explosive atmosphere, in the form of a cloud of combustible dust in the air, is not likely to occur in normal operation but, if it does occur, will persist for a short period only. For example, leaks from incorrectly fitted lids or spillages.
