My time at Alderley couldn’t have been better! Matt was incredibly knowledgeable and conveys what he knows well, as a good teacher should. Craig the assessor, clearly explained the assessments and made me feel comfortable throughout the course. The facilities were very accommodating, and lunch was superb. Thank you, Alderley.

Open Specialist Courses (CompEx)

CompEx Foundation Course

This course is part of the national scheme for the training and certification of core competence of personnel who work on equipment for use in explosive atmospheres.  

Our course not only covers the core CompEx unit qualifications (covering subjects like ATEX, DSEAR and general hazardous locations theory), but also adds information on international standards and schemes such as IECEx.

Our course also covers all of the latest updates and new Standards, ensuring you are covered for past, current and even future practices.

This course contains no practical skills training or practical assessment and is therefore more suited to anyone involved in Hazardous Area work that does not actually conduct installation or inspection of electrical equipment. Unlike the other CompEx units, no prior knowledge of hazardous areas is required for full participation in this unit.
The CompEx Foundation Course content covers the knowledge requirements for a ‘Responsible Person’ as defined by EN60079-14 Annex A (c-d)
The course can be delivered as an open course at our training Centre or delivered at your location, minimising travel and disturbance to the people attending the course.

  • Directives and regulations including ATEX & DSEAR
  • International schemes (NEC/IECEx)
  • Hazardous areas overview
