So he hands me a hacksaw and I start to saw on this one conduit. I get about three quarters of the way through when "BANG!" flash of light in the conduit, and the hacksaw blade now has a chunk missing out of it.
As a teen I was moving into my new bedroom, that the previous owner of the house had slopped paint all over the outlets. Obvious fire hazard, so I get mom to get me the necessary replacement outlets and covers (less than $6, not a big deal).
I flip the breaker off, tell mom I'm changing the outlets.
I'm working on the second outlet, turning the screwdriver. Have a nice grip on the outlet with the neutral and ground connected, working on the hot. Mom goes into the utility room to do some laundry, sees the flipped breaker and flips it on. Fortuantly when I twitched from the electricity I prompty shorted the outlet back out with the screwdriver.
Then sat there for a minute or two before yelling at mom.
Lockout/Tagout is there for a reason!
