Following CSA Z462 will prevent most of these injuries and almost all the fines. The standard came out in 2008 but many in Canada had been using the US, NFPA 70E before the Canadian version came out. I’m a member of Z462 and a big supporter of the methodology to prevent injuries and fatalities. Most companies who train, audit and follow up with procedural changes see real decreases in incidences. Most shocks are prevented by just wearing rubber gloves and leather protectors and most fatalities are prevented by also adding to that wearing arc rated flame resistant clothing. It is pretty simple to do. We have digested it into 7 electrical safe work habits in our training.
Good to see Canadian government recognition of arc flash.
