Interpreting the markings on Ex equipment can be demanding. The plate can carry codes for both IEC standards and the ATEX equipment directive. So what do all these letters and numbers really mean? How can you be sure the equipment has sufficient explosion protection to be installed in the necessary zone? This information is critical if you need to select and install equipment for a potentially hazardous area.

Internationally and on ships, the standards IEC 60079-14 require documentation of competence for those who are responsible for Ex areas, those who select and install Ex equipment and those who design Ex facilities. The standard IEC 60079-17 requires documented competence for responsible persons and technical personnel with a leading function, as well as operational technicians and technicians who carry out inspections and maintenance.

This course is aimed at electrotechnical and automation personnel and other personnel planning or working on electrical installations in potentially hazardous areas. The course will also be useful for manufacturers and suppliers of Ex equipment. Having completed this course, candidates will have gained good insight into how electrical equipment is Ex-marked, and what the different markings mean. Candidates will learn to distinguish between the different types of markings and make good decisions when selecting equipment to use in an installation in a potentially hazardous area.

On completion of this course you will receive a Certificate of Completion from Ocean Technologies Group, powered by Marlins, Seagull and Videotel.

Please note:  The assessment part of this course must be completed onboard ship or onshore in the offices of a registered shipping company or maritime institution. The Master/senior officer onboard or a senior official onshore must sign and stamp your application form to verify they have directly supervised your eLearning assessment(s). For Flag approved courses, please refer to the 'approvals' section below for further information.
