I can’t support this comment enough. My last job was chemical and biological safety oversight but had a lot of overlap with regular safety people. It takes no extra time to ensure a circuit is properly locked and tagged out because anyone working on that circuit should already have their own lock on it, using a gang lock if there are multiple people.
Then you still prove test prove. For those not in the biz, this means to test your sensing equipment on a known live circuit, test the circuit being worked on, then retest the tester as before because breakers get mislabeled and meters break all the time.
On that note, there’s the time an energized circuit almost killed my sister-in-law. She said she understood 120v wiring, so was changing out a light fixture. She asked me for some help with getting it mounted, so I asked her if the breaker was off, and she assured me it was. As I was working on it, it let out a loud pop, slightly zapped me, and blew the breaker.
I’m normally a very nice, chill person, but I was fucking livid. I asked her to show me the breaker she turned off and she pointed to the fucking wall switch. Someone had switched it on, likely out of habit. I inspected the wiring and found she used a cracked wire nut and overtightened it until the hot wire protruded well past the end. I wasn’t grounded but I was holding the fixture… with my left hand. I could have had a heart attack if I had been grounded
It’s a boomer joke, but I was what almost killed her. I had never been so angry with someone before. We still love her, but we don’t let her work on anything with stored energy anymore.
