This course provides a comprehensive technical approach to hazardous areas. It explains the subject of explosion protection applied to electrical equipment in such areas. The course offers detailed explanations of the principles involved, the techniques used, the management structures and requirements to comply with the harmonized international standards that are now in place. Where potentially flammable atmospheres are encountered in industrial processes, area classification is mandatory as part of a risk assessment for the management of health and safety; the issues are examined by providing the opportunity to apply this process and understand the importance and extent of the co-operation of the disciplines involved. Requirements of inspection and maintenance are examined to show the importance of their effectiveness once the correct installation has been properly achieved, and to enable management to form a structured and effective regime to assure safety.
 
This course would also be appropriate for supervisors and managers, with the emphasis on outlining the management responsibility and enabling them to complement and accommodate the needs of technical staff beneath them. It is a common problem that technical staff are trained in what needs to be done but their management does not appreciate this or understand it. This course will address these shortcomings.

How can an e-learning course be interactive?

Boredom can be a real danger, however, we use an interactive approach to our e-Learning – with live sessions instead of recordings.  The webinar software allows everyone to interact and involves participants in group work; including hands-on exercises with simulation software and remote laboratories where possible.  You can communicate with text messages, or live VoIP speech, or can even draw on the whiteboard during the sessions.
