9.5 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.
►Regardlessoftheirtypeofprotection,motorsmaynotbeusedinzone0.
►MotorsofunitgroupII,category2Gmaybeusedinzone1.
