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.

Benefits of eLearning to Employers
- Lower training costs: no travel or accommodation necessary
- Less downtime: short webinars (60-90 minutes) and flexible training methods means less time away from work
- Retain employees: keep staff who may be considering a qualification as full time study
- Increase efficiency: improve your engineering or technical employees’ skills and knowledge
- International insight: students will have access to internationally based professional instructors and students
How Does it Work?
EIT eLearning courses involve a combination of live, interactive sessions over the Internet with a professional instructor, set readings, and assignments. The courses include simulation software and remote laboratory applications to let you put theory to practice, and provide you with constant support from a dedicated Learning Support Officer.
Practical Exercises and Remote Laboratories
As part of the groundbreaking new way of teaching, our online engineering courses use a series of remote laboratories (labs) and simulation software, to facilitate your learning and to test the knowledge you gain during your course. These involve complete working labs set up at various locations of the world into which you will be able to log to and proceed through the various practical sessions.
These will be supplemented by simulation software, running either remotely or on your computer, to ensure you gain the requisite hands-on experience. No one can learn much solely from lectures, the labs and simulation software are designed to increase the absorption of the materials and to give you a practical orientation of the learning experience. All this will give you a solid, practical exposure to the key principles covered and will ensure that you obtain maximum benefit from your course.
