All covering Ex issues on site or related to shall be Ex competent. We may say, it is not anymore a questionmark today. There are good training programs available on the market (IECEx CoPC, CompEx, InHouse ones: E.g ExAM), but what about if all these individuals apply for a job and enter the site. Specially if the case the assessment / certification of Ex personnel competencies happened to be many years before (but still valid). Most of Ex personnel competencies are valid for 5 years.
It just happened:
At one hazardous area site few workers entered the O&G site with valid Ex personnel competency certificate (it would not be correct if I name the one), and the shock came afterwards. None what they learned (hopefully they did) practised it as per daily routine. They installed Ex JBs with Ex e glands, modified original specification, earthing was not in place, and many more.
At the end of the day the whole project team came together... whom to believe from now on?
They decided to establish an InHouse Personnel Competency measurement tool independent from any system asking basic awareness questions from all successful applicants.
We all learn from mistakes. Question: prior or ...?
Keep up good work!
