Definition of hazardous areas

Gas mixtures or vapor mixed

Powders

•Zone 0 - An atmosphere where a mixture of air and flammable substances in the form of gas, vapor or mist is present frequently, continuously or for long periods.

• Zone 1 - An environment in which a mixture of air and flammable substances in the form of gas, vapor or mist is likely to occur occasionally during normal operation.

• Zone 2 - An environment in which a mixture of air and flammable substances in the form of gas, vapor or mist is not likely to occur in normal operation, but, if it does occur, will persist for a short period.

• Zone 20 - An atmosphere where a cloud of combustible dust in air is present frequently, continuously or for long periods.

• Zone 21 - An atmosphere where a cloud of combustible dust in air is likely to occur occasionally during normal.

• Zone 22 - An atmosphere where a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period.
