Mojo: It sounds as though you shouldn't be in there. I was collecting a vibration data on a pump in an engine room aboard ship about 20 years ago and my arm accidently brushed against something that was energized with 480v 3 phase. My arm was pretty much dead for about an hour. Nothing like 120v.
I was in the Navy with a guy that did the same thing, but he lost his arm. Lucky he didn't die.
