Potentially explosive areas or premises are classed in zones according to how often an explosive atmosphere occurs and how long it lasts. The individual in charge of the operation is responsible for the risk area being classified.
Classification must be carried out by persons who are knowledgeable about the properties of the flammable products, the process as well as the equipment. Classification can take place in consultation with safety and electrical engineers and also process technicians.
Zone 0 and zone 20
Areas where an explosive atmosphere is present continuously for long periods or frequently.
Zone 1 and zone 21
Areas where an explosive atmosphere is likely to occur in normal operation.
Zone 2 and zone 22
Areas where an explosive atmosphere is not likely to occur in normal operation but if it does occur will only be for a short duration.
