I have seen worse. A tech at a company I was at was tired and not thinking clearly when he tried to take a voltage reading on a live 480VAC transformer with his fluke handheld meter set to resistance. The explosion woke him up without any damage to himself. Ofcouse it did make a big bang, blew his meter up, pitted the lugs on the transformer, and turned out the lights to the whole building. I have seen people who did know better getting dropped by sticking their hands into live 208VAC while mucking around in power sections of industrial machinery.

The people who get zapped and killed are the totaly clueless, and the been there done it 10,000x before people who just get stupid.
