About the course

This course provides an understanding of the hazards involved in using electrical equipment in potentially explosive atmospheres. It is based on the newly adopted international IEC Series which are directly applicable to most countries in the world.

Explosion-proof installations can be expensive to design, install and operate. The wider approaches described in these standards can significantly reduce costs whilst maintaining plant safety. The course explains the associated terminology and it correct use. It covers from area classification through to the selection of explosion-protected electrical apparatus, describing how protection is achieved and maintained in line with these international requirements.

Course Objectives

Provide a clear understanding of hazardous area current custom and practice with particular respect to the following:

  • Defining the hazard, classifying hazard materials, understanding the nature of the risk and the necessity to eliminate sources of ignition.
