Mechanical switching in an explosive atmosphere
Classification of the different Ex zones
Areas at risk of gas explosion Areas with combustible dust
Zone 0
Area in which there is a permanent or long-term explosive
atmosphere from a mixture of air with combustible
substances in the form of gas, vapour or fog.		 Zone 20
Area in which explosive atmosphere is present in the form of a cloud
of combustible dust in air constantly, long-term or frequently.
Zone 1
Area in which it is expected that an explosive atmosphere will
occur from a mixture of air with combustible substances in the
form of gas, vapour or fog during normal operation.		 Zone 21
Area in which it is expected that explosive atmosphere in the form
of a cloud of combustible dust in air will occasionally occur during
normal operation.
Zone 2
Area in which it is not expected that in normal operation an
explosive atmosphere from a mixture of air with combustible
substances occurs in the form of gas, vapor or fog, and if, then
only rarely and even briefly.		 Zone 22
Area in which, in normal operation, it is not expected that an explosive
atmosphere in the form of a cloud of combustible dust will occur in air,
but if it does occur, then only for a short time.
