Classification in zones according to Directive 99/92/CE:
Category 1
Zone 0 - Area in which (permanently, for long periods or often) an explosive atmosphere is present, consisting of a mixture of
air and inflammables in the form of gas, vapour or mist.
Zone 20 - Area in which (permanently, for long periods or often) an explosive atmosphere is present in the form of a
dust/powder cloud which is combustible in the air.
Category 2
Zone 1 - Area in which, during normal activities, the formation of an explosive atmosphere is probable, consisting
of a mixture of air and inflammables in the form of gas, vapours or mist.
Zone 21 - Area in which occasionally during normal activities the formation of an explosive atmosphere is probable,
in the form of a dust/powder cloud which is combustible in the air.
Category 3
Zone 2 - Area in which, during normal activities, the formation of an explosive atmosphere, consisting of a mixture of air and
inflammables in the form of gas, vapour or mist is not probable and, whenever this should occur,
it is only of a short duration
Zone 22 - Area in which, during normal activities, the formation of an explosive atmosphere in the form of a combustible
dust/powder cloud is not probable and, whenever this should occur, it is only of a short duration.
