Ex Hands-On

​

The Ex Hands-On course familiarises delegates with the forms and procedures used to repair hazardous area and ATEX equipment. It has been designed to ensure that managers, supervisors and technicians, who are involved with the repair of hazardous area equipment fully understand the practicalities of ensuring that equipment is repaired to maintain all the safety aspects embodied in the original design certificate and/or standards. Most engineers/technicians attend the Ex Theory and Ex Hands-on courses at the same time to maximise their  understanding of the concepts.

​

The course is for delegates, who have attended the first module on Hazardous Area and ATEX Theory. During the AEMT Ex Hands-on course they will gain experience of following the requirements of the Ex repair standard 60079-19 and other relevant standards to be able to measure flame paths, air gaps, and volumes. They will be assessed on their theory knowledge of the repair standard and on their practical ability to carry out the tasks at the end of the course. The course is vital for any electrical or mechanical engineers/technicians repairing equipment for hazardous areas.

​

The course has a balance of seminar and practical elements. All delegates fill in the “AEMT Ex Machine Repair Sheets” and take measurements of flame paths, volumes, learn about the importance of k and m values and complete condition sheets on Ex "d" machines.

 

Procedures for Ex “e” and Ex “n” are covered and also Ex tD.

 

The module's content includes:

  1. Health and Safety aspects including “Certificates of Safety” relating to the actual equipment being received.

  2. Best Workshop Practice: including the procedures that should be in place to repair Ex equipment.

  3. Procedures to be used on receipt of the apparatus.

  4. Dismantling: Recording Motor, Pump, apparatus details.  Customer information. Dismantling procedures.

 

Initial inspection and measurements:

  2. Initial Tests.

  3. Internal and External visual inspection.

  4. Terminal layout and inspection.

  5. Rigid flanged joint surfaces.

  6. Spigot joint gaps.

  7. Flame paths.

  8. Drilled holes.

  9. Bearings.

  10. Axial alignment.

 

Overhaul and Recovery:

  1. Including welding and metal spraying advice.

  2. Repair of threaded holes for fasteners, and recovery parameters.

  3. Final inspection & Reassembly.

 

Testing:

  1. Incorporating Core tests, winding tests, phase balance tests.

  2. Insulation resistance tests. Flash tests.

  3. Run tests/locked rotor tests.

  4. Final Reporting, Records and Labelling.

  5. Tools, equipment and standards requirements.

 

Online:

Our online course (when available) covers all aspects of the classroom based course, without the travel expense! 

​

While we are not able to provide equipment to practice on in our online course, we provide a comprehensive video tutorial for delegates to watch in their own time. We recommend delegates find a spare Ex d machine in their works which they can practise on, before they take their assessments with us. Not required for Hands-on Refreshers.

​

Ex Hands-On Refresher:

For delegates on the Ex Hands-On refresher course.  There will also be updates on revisions to ATEX, DSEAR, Standards, equipment and procedures that have occurred over the past three years.

 

Assessment:

There will be a multiple choice assessment on the procedures covered above as well as a practical assessment involving the use of the AEMT repair form to take the necessary records and measurements.

​

Certification

All delegates are assessed throughout the course with multiple choice questions, including diagrams, drawings and photographs. An AEMT Certificate of Assessment is issued to all successful delegates.

Technicians need to attend a Hands-on refresher course every three years to update them on any changes to the standards. They also have a comprehensive re-assessment of their ability and knowledge before issuing an updated certificate, which forms part of their overall competency record.

​
