IECEx Certified Personnel Scheme

What is the IECEx Personnel Competency Certification Scheme?

The safety of commercial facilities with hazardous locations depends strongly on the competence of those persons dealing with safety management, planning, installation, operation; inspection, maintenance, repair and similar activities.

International standards, such as the IEC 60079-10 series,IEC 60079-14, IEC 60079-17 and IEC 60079-19, define the required competence of personnel for aspects of electrical installations at all stages of their lifecycle. Applying such standards and conformity assessment principles and processes to the examination of personnel competence provides an independent validation of the ability of personnel to apply their knowledge and practical skills to a required quality level in workplace environments.

The IECEx CoPC scheme addresses the certification of personnel competence  involved  in  activities  through  twelve units  of competence:
Unit Ex 000 – Basic knowledge and awareness
Unit Ex 001 – Apply basic principles of protection in explosive atmospheres
Unit Ex 002 – Perform classification of hazardous areas
Unit Ex 003 – Install explosion-protected equipment and wiring systems
Unit Ex 004 – Maintain equipment in explosive atmospheres
Unit Ex 005 – Overhaul and repair of explosion-protected equipment
Unit Ex 006 – Test electrical installations in or associated with explosive atmospheres
Unit Ex 007 – Perform visual & close inspection of electrical installations in or associated with explosive atmospheres
Unit Ex 008 – Perform detailed inspection of electrical installations in or associated with explosive atmospheres
Unit Ex 009 – Design electrical installations in or associated with explosive atmospheres
Unit Ex 010 – Perform audit inspection of electrical installations in or associated with explosive atmospheres
Unit Ex 011 – Basic knowledge of the safety of hydrogen systems

Based on a modular competence structure taylor-made competence profiles can be certified which perfectly fit the actual obligation and tasks of the candidates in their jobs.

The IECEx scheme for certification of personnel competence provides independent verification that a person holding an IECEx CoPC has the ability to apply skills, knowledge, qualifications and experience to work safely in accordance with relevant international standards on explosive atmospheres. This can be especially important for contracted staff.
It is structured to provide separation and impartiality from any training schemes and therefore gives the highest level of integrity of assessment. The scheme recognizes that knowledge and skills could be obtained by any means such as tertiary education, internal company training, external private training, on the job mentoring, etc.

What is involved in examination by KSC for IECEx Certification?

To obtain an IECEx CoPC, a candidate prepares an application and submits it to an accepted IECEx Certification Body (ExCB) for IECEx 05 scheme like KSC Poland.

The candidate will undergo examination in order to assess the qualification and practical experience before receiving an IECEx certificate. Regular re-assessment ensures that the certified person maintains competences and sufficient knowledge about the relevant standards which may be revised and updated.

Relevant competence includes all aspects of work performance which should provide the evidence of:

1. qualifications (off job): this may be a university degree, a diploma, craftsman/trade training that is generally achieved through an education system
2. experience (on job): apprenticeship, trainee programme, direct supervision or mentoring are examples of the typical experience that would be considered
3. recent and relevant training (both on and off the job): it is essential that knowledge and skills are maintained; to achieve this, a competent person would be expected to attend refresher training or seminars, etc.

The IECEx PC Certificate is valid across international borders.

As well as the certificate itself, the person obtains an identification card with photo, providing instant proof of certification on-site. The CoPC certificate may be verified on the IECEx website.
