De-energize to avoid shock

Electrical workers – are you de-energizing equipment before performing work? If not, you could be putting yourself at risk of shock and arc flash.

There were several instances in 2017 where energized equipment left exposed to contact resulted in injury. Here are two examples we investigated:

A Technical Safety BC information bulletin and directive reiterate a BC Electrical Code requirement for work to be done only in a de-energized state -- unless a complete disconnection is not feasible. This is also addressed by WorkSafeBC's Guidelines Part 19 - Working on low voltage electrical equipment.

Electric shock is one of the safety risks Technical Safety BC has placed a priority on for 2018. Industry representatives were recently engaged to look closely at this safety risk which is now being analyzed using the fault tree methodology. The goal is to better understand what activities lead to certain safety risks and improve efforts to enhance safety.
