What are the limitations and initial intent of a “certificate of competence”?

<<Blog Topic>>

Today's companies operating within potentially explosive atmospheres have come a long way with regards to training, which is now mandated by most major industries

However, there are still a lot of misconceptions about the requirement of such trainings

Many applicants often ask ATEC prior to inquiring course contents or what competencies are to be assessed:

  • “What are your pass rates?”
  • “Can I have my certificate of competence by xx date?”
  • “Why do you need to have a copy of my qualifications?”

The initial intent of the certificate of competence is self explanatory – to certify someone’s competence. This process involves validating the candidates, experience, along with a verification of theoretical and practical underpinning knowledge.

While most early training was quite heavily focused on equipment certification, in response to one of Lord Cullen’s recommendations post Piper Alpha – the CompEx scheme was developed and 26 years later it has had a huge impact on practical safety in the workplace.

Additionally since 2010 the IECEx CoPC has added its “international” flavor to meet the same competencies referred to within IEC60079-14, ensuring that an operative, designer or responsible person (O/D/RP) understands:

  • The necessary skills and competence required for their scope of work (O/D/RP).
  • Their responsibilities and limitations when understanding or practising their scope of work

These limitations and the initial intent of a “certificate of competence” are always known and taken into consideration by the companies who are the benchmark of our industries.
