10.6 Explosion protection
regulations
► Following regulations have to be observed
for the use of equipment in hazardous areas
within the EU:
- Directive 1999/92/EC on minimum
requirements for improving the safety and
health protection of workers potentially at
risk from explosive atmospheres
- Regulation (EC) 1272/2008 (CLP)
► National rules and regulations additionally
have to be observed.
10.7 Classification of zones for
explosion hazard areas
Explosion hazard areas are defined 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 flammable gases, vapours or mists, following
classification 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 temprarily.
Explanation of the zone classification
when using drum pumps for flammable
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 flammable 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.
