The hazards of working in areas of high electrical potential are what has brought about the CRI syllabus for the Cert IV in hazardous areas course. This particular course is only taken by qualified electricians and those who have had some level of training to be able to identify the potential hazards and take measures to minimize them. The syllabus consists of five main subjects which cover the four main categories that can occur in any given hazardous area. One of these categories is the Electic Shock, which includes the effects of extreme temperatures on human body.

This particular subject deals with G St -free or the thermal shock as it is sometimes referred too. This subject is on the list of subjects on the CRI schedule which requires refresher courses every five days. It covers how the human body is affected by high temperatures from the electric shocks that can occur when working in hazardous areas. Once a student passes the certification exam, he or she will have the ability to work in the public service without a license and be able to work with the electrical equipment in high voltage power lines. A certificate of competency in the area of hazardous areas will not only help to protect workers but will also help them to receive higher pay for their jobs.

The cert is gap training is available in two formats, five-day courses and the six-day course. Both offer the students the ability to gain the knowledge they need in order to work safely around hazardous areas. The five day course is designed to teach students the basics of working in hazardous areas and then provide refresher courses for those who wish to obtain their certificate to certify them for the six-day certification exam.
