ATEX Zones
Hazardous areas are any location where there is risk of an explosion.The risk level of an explosion is determined by the frequency and durationof the occurrence of an explosive atmosphere.
- Zone 0 / 20This is an area in which an explosive atmosphere is present continuously for long periods of time or will frequently occur.
- Zone 1 / 21This is an area in which an explosive atmosphere is likely to occur occasionally in normal operation. It may exist because of repair, maintenance operations, or leakage.
- Zone 2 / 22This is a place in which an explosive atmosphere is not likely to occur in normal operation but, if it does occur, will persist for a short period only. These areas only become hazardous in case of an accident or some unusual operating condition.
