A hazardous area is one in which there is a potential risk of explosion due to the explosive gases, vapours, mists or dust or a combination, during the operation of a plant or process, such as petrochemical plants, offshore oil rigs, fuel filling stations, timber mills, coal mines, flour mills, paint spray booths, sewerage treatment plants,  explosive warehouse etc. Special consideration must be taken into the design, manufacture, installation and use of equipment in such hazardous areas.

The relative standards referred to:

• IEC 60079-14
• EN 60079-14
• AS/NZS 60079-14
• SANS 60079-14

An explosion occures under the following three elements,pls refer to the illustrative chart

In order to avoid the explosion , one of the above mentioned elements must be controlled or removed, these including:

◆Reducing the number of flammable gases or dust

preventing the formation of explosive atmosphere(remove air or oxsigen)

avoiding the fire source


In the case that explosion already occured , then measures must be taken to control explosion migration outside to cause damage of life or property.

These measures are:

◆Contain the explosion.

Suppress the explosion actively or passively.

Vent or relieve the explosion.

GASZone 0
Areas where flommable and explosive gases persist or exist for a long time (such as more than l,00 hours per year).
Zone 1Areas where flammable and explosive gases exist during normal operation (such as 10-1000 hours per year).
Zone 2Areas where flammable and explosive gases usuolly do not exist during normal operotion, but if there are, they only exist for a short time
Zone 20Areas where explosive dust or a mixture of combustible fibers and air persists or exists for a long time.
Zone 21Areas where explosive dust or a mixture of combustible fibers and air may occur.
