CompEx (meaning Competency in Ex atmospheres) is a global certification scheme for electrical and mechanical craftspersons and designers working in potentially explosive atmospheres. The scheme is operated by JTLimited, UK and is accredited by UKAS to ISO/IEC 17024.
The scheme was created by EEMUA (Engineering Equipment and Materials Users' Association) to satisfy the general competency requirements of BS EN 60079 (IEC 60079), parts 10, 14 and 17. The requirements are currently explicitly detailed in EN 60079 Part 14 Annex F, detailing knowledge/skills and competency requirements for responsible persons, operatives and designers.
The scheme is broken down to twelve units covering different actions and hazardous area concepts.
CompEx has now developed core competency modules specifically for the USA, and provides NEC500 & NEC505 Ex01-Ex04. These are delivered at the approved CompEx Centre : the Atec Training Academy : advertising . The course delivers the NEC500 & NEC505 Code of Practice and encompasses the API RP 14FZ - Recommended Practice for Fixed and Floating Offshore Petroleum Facilities for Unclassified and Class 1, Zone 0, Zone 1, and Zone 2 locations in the delivery.
