Description

The dust and fumes put into air by much industrial process create an environment which is classified as electrically hazardous. Processing plants in petrochemicals and oil & gas field’s requirements for the selection of electrical equipment to suit the area classification. The course provide essential information on the main principles of hazardous areas , risks, ignition properties, the different types of protection for electrical apparatus in flammable atmospheres, the essentials of installation requirements, equipment certification, and information on the different types of protection for hazardous area electrical apparatus (ex d, e, ia/ib, p, n, etc.). The different requirements of iec stander 60079-…. The application of selected equipment in different hazardous area.

Course Objectives

The course provide essential information on the main principles of hazardous areas , risks, ignition properties, the different types of protection for electrical apparatus in flammable atmospheres, the essentials of installation requirements, equipment certification, and information on the different types of protection for hazardous area electrical apparatus (ex d, e, ia/ib, p, n, etc.).
