The cable had been wired into a distribution board and was not safely isolated; Michael suffered a fatal electric shock. Over the years, leading bodies, such as the Electrical Safety Roundtable, have worked to develop procedures and protocols designed to prevent injuries and fatalities caused by a lack of safe isolation.

On the left of the image it reads 'What Are CAT Ratings?' in white and yellow block lettering. In summary, CAT ratings are overvoltage categories; they are safety ratings that indicate the types of electrical environments in which test and measurement instruments can be safely used. Understanding these categories is crucial to ensuring that you select the correct tool when working on an electrical installation.[1] Continue reading →
