Explosive atmosphere
P
erform a risk assessment for any risks due to the process or process environment.
Evaluate the effects the use of the product and the operational processes may have on
the classification of the hazardous area. The process might cause the area to increase
or the zone classification to change. Implement the risk reduction measures needed,
including use of personal protective equipment.
If potentially explosive liquids will be used with BPG columns consult local authorities
regarding local rules and regulations before installing or operating.
The column can be placed in an area with explosive atmosphere according to EU ATEX
workplace directive, Zone 2.
Definition of the zone
a
ccording to the direc-
tive: Zone 2
A place in which an explosive atmosphere consisting
of a mixture with air of flammable substances in the
form of gas, vapour or mist is not likely to occur in
normal operation but, if it does occur, will persist for a
short period only.
The column does not fall under the ATEX equipment directive, and as a result it is not
m
arked with EX labels, but it fulfills the explosion safety requirements in the directive’s
harmonized standards, for example EN 13463-1 or EN ISO 80079-36.
This is valid for the BPG column in its standard execution and with a grounding cable,
see Grounding kit, on page 32. Any additional accessory or equipment must carry EX-
marking or be assessed to be in conformity with the EU ATEX workplace directive.
