We try to make sure even electricians understand that contact with higher voltages results in BOTH arc flash and shock. This painter received a bad burn from contact with a powerline.
His clothing ignited. A lot of the burns in these incidents is from the burning clothing. Workers need to keep themselves and tools at least 10 ft (3m) from powerlines up to 50kV to avoid this hazard. This guy probably didn’t know this rule. If you can’t stay that far away working, you should call the power company to have the line de-energized or covered. This really requires a qualified electrical worker.
