Working safely in hazardous areas
Explosion protection is a central element of safety engineering. Its primary function is to prevent explosions or limit dangerous effects when explosions occur –with the aim of protecting people, assets, and the environment.
An explosion-hazardous area is a place where concentrations of flammable gases, vapors, or dusts may be present. Electrical devices used in such areas must be specially designed and tested to ensure that it does not they do not increase the risk of explosions.
The principle of a device designed, for example, in accordance with the “intrinsic safety” type of protection is to limit the amount of energy in the circuit to a non-ignitable level. This means that no ignition source can occur in the form of a spark or due to a thermal effect.
