IEC 60079 is concerned with the classification of areas where flammable gas or vapour or mist hazards may be present. The classification may be used as a basis to support the proper selection and installation of equipment for use in a hazardous area.
IEC 60079 is intended to be applied where there may be an ignition hazard due to the presence of flammable gas or vapour, mixed with air under normal atmospheric conditions.
An area classified non-hazardous, in accordance with this Standard, may not necessarily be safe in all respects as there may be toxic and chemical hazards present.
