8.3 Classication of zones for explosion hazard areas
Explosionhazardareasaredenedasareasinwhichexplosiveatmospheresmayoccurinpotentially
dangerous volumes on account of local and operational conditions.
Areasinwhichexplosionsmayoccuronaccountofammablegases,vapoursormists,following
classicationofzonesisapplied:
• Zone 0: Dangerous explosive atmosphere persists constantly or for a long time.
• Zone 1: Dangerous explosive atmosphere persists occasionally.
• Zone2:Dangerousexplosiveatmospherepersistsrarelyandbriey.
Explanation of the zone classication when using drum pumps for ammable liquids
• Inside the drum or container. Zone 0
• Bungholeofthedrumortheupperedgeofthecontainer:Boundarybetweenzone0andzone1
• Rooms in which media are transferred from one drum or container to another: Zone 1
The result for drum and container pumps is:
►OnlypumptubesofunitgroupII,category1/2Gmaybeusedtopumpammableliquids.
►Donotusemotorsinzone0,regardlessoftheirprotectionclass.
►UsemotorsofunitgroupII,category2Ginzone1.
8.4 Traceability
