Competency in Explosive atmospheres (CompEx) Awareness Course


COURSE BENEFITS & AIM:To ensure that delegates have an underpinning knowledge unit which gives an overview of the requirements of achieving and maintaining safe installations in hazardous areas while enabling a greater appreciation of the hazards associated with working in explosive atmospheres and the promotion of safe working practices.

This awareness course provides an ideal introduction to CompEx. Following successful completion of this level candidates can develop their competence further to gain a certificate of core competence in additional Ex atmospheres modules.

At the end of the course candidates will be able to:

Recommend the remedial action required to maintain hazardous area equipment to meet the required standards.
Select the protection concept, enclosure / equipment, components and install correctly in hazardous areas.
Understand how to identify problems with equipment installed in hazardous areas with respect to the appropriate British, European and IEC standards.
Understand that equipment could be a source of ignition that could contribute to an explosion.
Understand the concept of area classification and the need to zone flammable atmospheres accordingly.
Be able to understand the terminology and definitions associated with hazardous areas. Understand the various protection concepts namely EXd, EXE, EXn etc.

WHO WILL BENEFIT:

Electrician, Technical Assistants, Supervisors, Contract Managers and Senior Management who work or are associated with Hazardous Areas.
