Who is it for

The course is aimed to give mechanical engineers, supervisors and technicians an understanding of electrical and mechanical hazards that can give rise to danger in the workplace. Individuals will have the opportunity to demonstrate their competency in the preparation, installation, inspection and maintenance of mechanical equipment in potentially explosive atmospheres and hazardous areas.


Prior to attendance on the course, the Employer must provide written evidence of the candidate’s mechanical competency. Course delegates are required to possess relevant mechanical qualifications and evidence must be brought to the course. Candidates who cannot provide evidence of their qualifications or who do not have an Employer to complete the competency letter will receive a non-technical person’s certificate. The JTL registration form must be completed and brought to the course, along with photographic identification (ie passport/photo driving licence). All personnel attending the course should have a good understanding of the English Language and Technical Engineering terminology. The CompEx Toolbox guide is provided.
