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 Ex Refresher course is for delegates requiring a three-year refresh of their knowledge and a reassessment of their ability, to renew their certificate. Delegates will be re-assessed on their workmanship and competency.

The course also updates delegates on recent changes in standards, or equipment, and answers any problems encountered by delegates in the group discussions. The Ex Repair Refresher course now takes place over 3 days.

The course programmes rely upon the full involvement of the delegates in discussions and exercises.
