Zones and Equipment Categories
Zones		Typical Definitions of Zones (for guidance only)	ATEX Minimum Permissible Equipment Category for Zone	Minimum Equipment Integrity Requirement
Gases and Vapours zones	Dust	Explosive atmosphere is present continuously, for long periods or frequently	1	Equipment must be safe under normal operation, expected and rare malfunction
0	20		1
1	21	Explosive atmosphere is likely to occur under normal operation, occasionally	2	Equipment must be safe under normal operation, expected malfunction
2	22	Explosive atmosphere may occur under abnormal operation and persist for a short period only	3	Equipment must be safe under normal operation.
The higher the probability of an explosive atmosphere occuring and persisting, the lower the allowable potential risk of ignition and the higher the safety integrity requirements of the equipment to be installed. The relationship between zones and equipment categories can be varied following a complete risk assessment.
