I've had more electrical shocks than most, I worked in the electrical buiz for over 40 years. Got most of my zaps in the ship yards. A lot of welding shocks too. As an electrician we'd hold our boxes where we want them placed and a welder would tack it on where we want it, then we'd straighten it up and he'd tack it again. each time an electrical current goes through the box and if you're grounded at all you get the tag. elbows,knees, bad boots, holding you're self in place in awkward positions in cramped quarters getting grounded just happened.....
I also usually worked hot, too much time and trouble finding the correct breakers to shut everything down. I also didn't like shutting off 3-4 offices to replaces a ballast in the hospital I worked all 347volt. I changed hundreds of ballasts zapped 2-3 times twice on the same fixture...let me tell you 347 hurts the heart....Corridor lighting up in a metal valance box on a 6ft ladder. The first time I got knocked off and landed on my feet....no biggy...no one saw.....I shook it off ..I'm good to go...second one floored me ladder fell I fell hurt like fk I got up woozy nurses running towards me, tools on the ground, old folks in wheelchairs coming to assist......Big flash and bang, blew the breaker....Had to have a fking incident report......and a safety lecture by my bosses that knew dam well what I was doing all along....all for a Workman's Compensation show....2 weeks later I was back doing ballasts the same way. So I know a bit about getting tagged.
