Electric Installation in Hazardous Area course gives participnts a trough understanding of selection, installation and maintenance of electrical equipment in Hazardous Areas. It covers the principles of Hazardous Area classification, explosion protection techniques, equipment selection, equipment installation requirements, inspections and procedures for breakdowns
BENEFITS
* Defines the hazard, classifying hazard materials, understanding the nature of the risk and the necessity to eliminate sources of ignition
* Defines The relationship between area classification and the various different types of Ex apparatus
* Selects the electric equipments for hazaedous Area * install and maintenance of the different types of equipment i.e. flameproof, increased safety, intrinsic safety etc
