Ex Theory Only

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.

To complete the full AEMT Ex Training, the Ex Hands-on course must be taken as part of a 4-day course.
