Industrial facilities that have a chance of the environmental conditions causing an explosion are certified as Atex zones and defined under European directive 99/92/EC also known as ATEX 137 or the ATEX workplace directive
There are six zones which cover the types of hazardous environments based on the frequency and duration of the occurrence of an explosion.
Area Classification Zone Criteria
Zone 0 Zone 20 Explosion risk present continuously or for long periods of time.
Zone 1 Zone 21 Explosion risk likely to occur in normal operation occasionally.
Zone 2 Zone 22 Explosion risk unlikely to occur in normal operation,if it does will only be for short periods.
If you have any requirements for operator protection within an ATEX environment we will be happy to discuss your options.
