What is Ex training?

Ex = Explosive atmospheres


Ex training is the training for the personnel working in or related to explosive atmospheres (dust, gas or mine) so that they are able to carry out work associated with Ex equipment without creating the possible ignition sources that ignite explosions in hazardous areas.


Why is Ex training important?


Ex training is a mandatory requirement according to the IEC International Standards. As people are the weakest link in most safety chains and there is no exception in hazardous areas, the regulation is aimed to prevent potential accidents which will not only destroy property but also cost human lives and cause severe injuries. Thus, that will help to make the world a safer place for everyone.


How to choose the right Ex training course for yourself or your team?


TESV has provided several options of Ex training and we understand picking the right course for yourself or your team can be rather confusing. Our advice for you to get started is that you can base on 2 steps to find out the answer.

  • Step 1: Understand available courses and their objectives

  • Step 2: Be clear about the goals and the outcome do you want to achieve to decide which course is suitable for you

What courses of Ex training are provided by TESV?

Depend on the course purpose, the difficulty of the final test and the course certificate, the Ex programs are classified into 3 main groups in TESV as following:

Ex Training:

The purpose of the program is to provide the participants with the Ex knowledge according to the IEC International standards so that they can understand and apply it while actually working with Ex equipment.

Therefore, the final test is just to check if the participants understand the knowledge of 3 training days and it is not difficult. When passing the final test, the participants will get the certificate issued by Trainor and the certificate will be uploaded on the Trainor’s website.


*Trainor is a leading training provider of Ex training in Northern Europe. Trainor’s head office is in Norway. The relationship between Trainor and TESV has a long story when TESV has been separated from a Trainor’s branch company to an independent identity since August of 2020.

IECEx CoPC Certification:

IECEx CoPC = The IECEx Scheme for Certification of Personnel Competence

The IECEx scheme for certification of personnel competence provides independent verification that a person holding an IECEx CoPC has the ability to apply his/ her skills, knowledge, qualifications and experience to work safely in accordance with relevant international standards on explosive atmospheres.

The purpose of this program is testing not training. Therefore, the exam test of IECEx CoPC is quite difficult and challenging for the candidates. When passing the exam test, the candidates will get the certificate issued by IECEx and the certificate will be uploaded on the IECEx’s website.

Preparatory course:

The course is to help the participants to refresh the Ex knowledge which they already obtained so that they will have more possibilities to pass the official exam. The purpose of this program is refreshment, not training. Therefore, there is no certificate after completing the course and the final test is somehow a trial test for the participants to get used to the test format of IECEx CoPC.

* If the participants haven’t got any proper Ex training, we highly recommend you to take the Ex training before registering for the preparatory courses.


Which Ex course is suitable for you or your team?


The second step that you could consider to pick up the right Ex course is thinking clearly what your own goals or the company goals are in general and what you hope to achieve as a result of undertaking the course. Also, you should make an honest assessment of the Ex level and Ex training history of yourself or your team.


This will help you find the suitable course for your needs, and prevent you or your company from wasting the time and money on the course that is either too advanced to follow or too basic to benefit from.
