Description
The use of electrical motors in potentially explosive atmospheres is quite frequent these days. These motors have to be constructed in such a way that there is no risk of an explosion. An Explosion occurs when the following situations occur:
– presence of potentially explosive atmosphere
– existence of a source of ignition
– possibility of transmission of the explosion
Classification of Hazardous Environment
According to IS: 5572, Hazardous areas are classified in the following ways depending on the degree of probability of the presence of hazardous atmosphere.
