Explosion-protected (Ex) equipment, such as motors, pumps and gearboxes, is built and certified to stay safe in places where flammable gases, vapours or dusts may be present. When it is repaired, overhauled or reclaimed, the work has to keep that protection intact, because a poor repair can compromise it.
Our course teaches how to do that work properly. It covers the protection concepts, the legal, risk assessment and health and safety requirements, and the International Electrotechnical Commission (IEC) repair standard, 60079-19, so that repaired equipment complies with the original certification it was manufactured to, or the original standards used.
The course is for people who repair, overhaul or maintain Ex equipment, and for the companies that employ them: motor rewinders and repair workshops, service centres working towards or holding IECEx certification, and the engineers and managers responsible for signing off Ex repairs. IECEx is the IEC System for Certification to Standards relating to Equipment for Use in Explosive Atmospheres.
It is also the right course if you are working towards IECEx certified competency (the Certification of Personnel Competence, or CoPC), because AEMT is an IECEx Recognised Training Provider and the training is delivered to IECEx Unit 005.
If you use Ex equipment rather than repair it, our End User Awareness course may suit you better.
You can take the Ex Repair course in a classroom, in the UK and around the world, or online at your own pace. Classroom course details or online course details.
This course exceeded my expectations. The trainer explained complex topics in a simple and practical way, encouraged participation, and created a comfortable learning environment. Every session was valuable and well-paced. Honestly, this was one of the best courses I’ve attended. The trainer’s energy, clarity, and passion made every session enjoyable and easy to follow, I truly appreciate the effort and professionalism involved in delivering such a high-quality course.

The meeting and presentation was concise and effective. Karl was able to relate everything in layman terms, to ensure we all understood catering for all levels of experience. The study and reference material was up to date with the latest regulations .
The practical was in-depth and gave us a good understanding of the measurements and how to apply them with the calculations .
What I did enjoy was the open discussions , that opened our minds to the problems that some armature winders find with ATEX regulations,
and information they require when working on ATEX motors.

This training enhanced my understanding of Ex equipment repair standards, certification requirements, and safety compliance in hazardous areas — knowledge that is vital for ensuring reliability and operational excellence in industrial environments.
Looking forward to applying these learnings in upcoming projects and continuing to contribute to safety, quality, and compliance excellence.

The course gives you a thorough knowledge of how different protection concepts and standards should be used when overhauling, repairing and reclaiming hazardous area equipment. It covers ATEX, IECEx and the 60079-19 standard. You can take it in a classroom with our trainers, or online at your own pace.
By the end of the course you can expect to have:
Jump to: Classroom course or Online course
Learn alongside other repairers in a three-day course led by our trainers. Refreshers and newcomers train together, so newcomers learn from experienced repairers and refreshers get a whole extra day to make sure they are up to speed.
We run courses in the UK and around the world, and can bring a bespoke course to your own site for your team.
Book any 2027 course date before 31 December 2026 and you pay the 2026 price.
Prices for bookings made from January 2027.
The online course has the same learning aims as the classroom course, in your own time. It is delivered in English, there are no fixed dates, you work through it at your own pace, and there is no time limit for finishing. It suits engineers who cannot spare three days away from the workshop, companies training people on different schedules, and anyone who is not near one of our classroom locations. It is also a more sustainable alternative to travelling to a classroom.
You work through the theory online, section by section, with a quiz for each section. Once you have completed and passed the theory, your practical assessment is booked with one of our trainers.
The practical is a live online session. You will need an Ex d (flameproof) motor available, and your trainer will measure flamepaths and carry out the other checks with you.
Refreshers do not need to take the practical assessment. A practical one-to-one bolt-on is also available on request.
You will need a computer and an internet connection, and a good standard of written and spoken English, or access to an interpreter.

Competence comes from experience built up in the workplace under the supervision of a 'Responsible Person'.
The course gives delegates an understanding of the technical standards and documentation required to complete the repair, overhaul or reclamation of hazardous area equipment.
Delegates will receive a Certificate of Assessment when completing the course, or a Certificate of Attendance for attending the course, but have not passed the assessments.

Karl has worked in the electro-mechanical industry since 1987 and leads AEMT's training programme, as well as providing ongoing technical support to members. He trained as a time-served rewinder and fitter, and was the Responsible Person for signing off all Ex equipment at Kirkby Lindsey.
Karl delivers the Ex Repair Training course in the classroom and online, and carries out the live practical assessments for online delegates.
The first BEAMA/AEMT "Code of Practice for the Repair and Overhaul of Ex Electrical Apparatus" had input from major users of Hazardous Area Ex Equipment, and the Health and Safety Executive (HSE). It was subsequently adopted as the British and European Standard BS EN 60079-19, and International Standard IEC 60079-19, which is now used as the basis to audit companies to IECEx Certified Service Facilities. They are the recognised international standards to which Ex equipment should be repaired and overhauled. Since 1984 the AEMT has trained delegates from the repair industry, and personnel from the major oil, chemical, gas and water treatment companies from around the world. Preceding the publication of the first code of practice for The Repair and Overhaul of Electrical Equipment for use in Potentially Explosive Atmospheres, the association has put together a selection of modules covering the Theory and Practical nature to ATEX and IECEx equipment repair. The association has trained staff in IECEx Certified Service Facilities in the UK, Gulf, and South East Asia, as well as engineers from many international oil, gas, and chemical companies. A number of delegates have also gone on to be successfully assessed and audited for their individual IECEx Personal Competency (CoPC) Certificates.
