The CompEx training modules enable companies and their employees to recognize and manage hazardous locations safely. Successful completion of a CompEx course provides confirmation of the competency of individuals who work in, or design equipment for, potentially explosive atmospheres.

Course Information

The CompEx Ex12 course meets the competency requirements of IEC 60079-14:2013 for designers (Explosive atmospheres: Electrical Installations Design, Selection and Erection). Bring your experience and test your competency with the IEC60079-14 Standard. Candidates in this course will actively participate in discussions of the risks associated with the correct design, selection, and assembly of equipment used in explosive atmospheres. During the 5-day course, candidates will receive an in-depth review and be tested on the following:

  • ATEX Legislation, Directives 2014/34/EU, Article 114 (relating to equipment and protective systems intended for use in potentially explosive atmospheres), and ATEX 137 (refers to minimum requirements for improving the health and safety protection of workers at risk from an explosive atmosphere).
  • Markings
  • Classifications per Zone system (0, 1, 2 for Gases; 20, 21, 22 for Dusts)
  • A detailed review of IEC 60079-14:2013 (BS EN 60079-14:2014)
  • Equipment protection levels (EPLs), Hazloc documentation
  • Grounding and bonding
  • Increased safety
  • Intrinsically safe electrical installations and related calculations


After the Candidate has successfully completed the course, he/she will receive a Certificate of Core Competence, Explosive Atmosphere – Application Design Engineer Module. Receiving this certificate demonstrates that you have met the rigor outlined in the Standard:ISO/IEC 17024 – General requirements for bodies operating certification schemes for persons.


As well, each course attendee is given a letter that:

  1. Confirms his/her attendance in the course, and
  2. Outlines each topic covered along with the time spent on each.

This letter supports the candidate’s application for professional development credits.

Courses are led by Hazardous Location Industry expert Brian Schneider, a global specialist in intrinsic safety and flame-proof/explosion designs, evaluations, and a senior member of the Canadian Electrical Code (CEC) Section 18 Committee. Brian has designed and built laboratories in Canada and Europe that test hazardous locations equipment in various explosive atmospheres.

CompEx History

CompEx History

167 lives were lost in the North Sea Piper Alpha disaster on July 6, 1988.


A 13-month investigation took place in order to determine the cause of the disaster and to ensure that it never happened again. (Source: The Hon. Lord Cullen, The Public Inquiry into the Piper Alpha Disaster. The Department of Energy. Vol 1-2. November 1990). The inquiry resulted in 106 recommendations for changes to North Sea safety procedures, all were accepted by the industry.


As elucidated on the CompEx webpage (, the CompEx Scheme was initiated in 1993 as a direct result of this investigation, its mandate is to raise the level of safety in potentially explosive working environments. It is the recognised global scheme for the protection of oil, gas and chemical workers in both offshore and onshore activities. The scheme assesses the competency of employees and contract staff who are working in potentially explosive environments. It also offers some reassurance to employers managing the safety of these potentially hazardous workplaces and may provide the added benefit of reducing insurance costs.


The CompEx Scheme was developed by the Engineering Equipment and Materials Users’ Association (EEMUA), industry experts and JT Limited. JT Limited, the CompEx Certification Body, is internationally accredited by UKAS (United Kingdom Accreditation Service) to ISO/IEC 17024: 2012 Conformity Assessment – ‘General Requirements for bodies operating Certification of Persons’.


The CompEx modules are recognised by industry as a sound methodology for proving core competence of the workforce engaged in Hazardous area work. This work can include the installation, commissioning and inspection of electrical, instrumentation and mechanical equipment which is often designed specifically for use in industries such as off-shore, petrochemical, pharmaceutical and dust environments such as sugar, flour and chip (oriented-strand) board.


The Piper Alpha tragedy is one that is often quoted in the literature as being an example “… of what happens when production, schedule, and cost come before investments in comprehensive system safety.”
