Explosion Proof Products

Flammable gases, mists and dusts, together with oxygen, form explosive atmospheres. Ignition of such atmospheres may cause serious damage to personnel and equipment.

Explosion takes place in the condition of the following factors:

  • Flammable substances (gas, vapour, mist or dust) in a suitable distribution and concentration
    Oxygen (from the air)
  • Ignition source

An explosive atmosphere occurs if the substance-air mixture lies within a certain concentration range, which is defined as Explosion Limits. Explosion limits depend on the ambient pressure and oxygen concentration of the air.

In order to avoid explosions and consequential dangers, the operator must incorporate effective explosion protection precautions into plant.

The principle of full explosion requires that explosion protection measures be taken in the following order:

  • Measure to prevent formation of dangerous explosive atmospheres.
  • Measure to prevent ignition of dangerous explosive atmospheres.
  • Measure to restrict the effects of explosion to a safe level.



Classification of Zones

Hazardous areas are classified into Zones, depending on the composition and presence of an explosive atmosphere. This enables both selection of suitable equipment and appropriate electrical installation.
Electrical apparatus for use in hazardous areas are assigned to various categories. The additional character G (gas) or D (dust) specifies whether the electrical apparatus may be installed in gas or dust hazardous areas.

Classification of Zones and use of equipment

  • Zone 0 Equipment with type test certificate
  • Zone 1 Equipment with type test certificate
  • Zone 2 Equipment complying with the basic requirements of Directive 2014/34/EU (Equipment certified for Zone 0 and 1 can also be used)
