    And that arc flash’s temperature is several times hotter than the surface of the sun. It’s hot enough to instantly vaporize any surrounding metal, meaning that if you manage to survive being near an arc flash, there’s a chance that you’ll end up with tiny metal shards in your lungs, when they cool down after you breathe them in. Arc flashes are scary stuff.

      Arc flash hazard training messed me up. They showed a video where a guy is working on some switchgear when suddenly the frame is all white and then the guy is just GONE, but the floor and everything around where he was is a different, very red, color. That “if” regarding survival is doing some heavy lifting.

        Grandpa worked in a power station back in the days of yore.

        Left the generator they were working on as he needed a tool. While he was gone an arc flash deleted his co-worker.

        Oh, absolutely. As my instructor put it, if you cause an arc flash and are killed instantly, you got off lucky. Because if you survive, your body will be severely damaged for the rest of your life.

        Those trainings put the fear into you for good reason. I don’t fuck with high voltage at all, shit is way too scary for me.

        IBEW local 26 here. They showed me that video too. That shook me for sure.

        It was the first class experience I’ve had in the trade. That video was the last thing he showed us at the end of class.

        Last thing he said was “don’t work hot” as we’re all packing up.
