I don't know. My guess is he at least went to the hospital but I don't know and hope my guess doesn't play down the dangers. People have been hit by lightning and survived and my physics teacher from college says you just need two electrodes and a D battery to stop a heart. I've heard of people losing their arms from touching the overhead wires on trains.

I think it is an old video because workers wear protection suites and there exists equipment to do what he did manually. I'm thinking it must be part of a training / safety video today which might be why it is on the internet.

I guess this is why I like playing with my 5 volt microcontrollers :)

I watched another video of a survivor of an arc flash accident and the picture looked like there was complete fire coming out of the spot where the accident happend. He wasn't using an arc shield. The reason why I'm not putting the video up is because it is graphic but he spent 15 months in the hospital, had 2nd and 3rd degree burns and wasn't expected to survive but had several skin graphs and he responded to medication for infection. He had a lot of rehab and was one of the fortunate ones.
