I've had some close calls. I almost got decapitated by a 1/4" sheet of aluminum. I was running a 100' skyhook, and had a guy about 70' up working on a sign, he took the bottom plate off to access the lamps, and placed it into the ladder rungs and it started sliding down the boom. I was walking around the truck to find out what the weird sound was, and was standing at the back of the boom and something told me to duck, and just as I did, the aluminum took off my hard hat, and cut the top of it off. Had I not, it would have hit me in the neck.
I was working on installing some neon letters for a new store, and since the electricians were not there, and no electrical had been run, we placed the 15,000 v transformers in the boxes, and ran the home runs. I was outside connecting the electrodes. The last thing I remember was seeing a flash of red, and then waking up in the bottom of the bucket. My helper was on the ground freaking out. He said that I didn't respond for about 15 seconds. When I realized that the electricians came in after us and hooked it up, then threw the switch...
