Ex Theory & Hands-on

Ex Theory & Hands-on

We specialise on Units Ex 005 of the IECEx Recognised Training Provider Programme (RTPP). This focuses on the IEC BS EN 60079-19 standard on repair, overhaul and reclamation of Ex equipment.

The aims of the course are to give delegates a thorough knowledge of how the different protection concepts and standards should be used when overhauling, repairing, or reclaiming Ex equipment suitable for each zoned area.

The Ex Theory is a two-day course that focuses on the theory behind Ex equipment. The Ex Hands-on two-day course gives hands-on practical experience. After completing the assessments for both modules, the full course is completed.
