Electrical Equipment in Potentially Hazardous Areas
<-- Back to EX and HV training
5 Day Course
Hazardous locations (also described as hazardous zones) are locations where explosive hazards may exist due to flammable gases, vapours or dusts. Safe methods of selection, installation and maintenance of electrical and instrumentation equipment, suitable for use in such zones, are described in this course which utilises the current British and Euro-norm Standards applicable throughout the European Union.
All personnel (examples are engineering, drafting, technicians, electricians) involved in the selection, installation or maintenance of electrical or instrumentation equipment in potentially hazardous areas.
None required. However most suitable for engineering personnel employed in the oil and gas industry.
Upon completion of this course and a successful assessment, the student should be capable of selecting, installing and maintaining electrical and instrumentation equipment in potentially hazardous areas.
