Advanced Inspector Certification

Advanced Lead Ex Inspector Certification

This course allows Professional Inspectors to demonstrate advanced/lead inspection skills beyond the minimum basic industry qualifications.

The advanced lead inspectors’ course is intended to both verify and improve the knowledge, skill and competency of the candidate with regards to the full requirements for inspection and maintenance. This course is specifically designed to bridge the “gap” between the core competency level of the inspection modules associated with CompEx Ex02, Ex04 and Ex06, and the CompEx Ex14 Responsible Persons course and IECEx CoCP equivalents.

Course Synopsis

This four day course is intended to give an in-depth awareness to the candidate with regards to explosive atmospheres formed by gases, vapours, mists and combustible dusts. It covers an analysis of the inspection and maintenance methodology associated with electrical and non-electrical equipment for use in explosive atmospheres.  As the persons attending the course are experienced electrical inspectors or at an equivalent senior level, the course covers the basic and more in-depth elements of inspection, testing and maintenance requirements of IEC 60079-17.
