Its not the voltage...
Once dropped a wrench (spanner in the uk) while working above a 48V battery bank, used as primary power for the local city telco. Did it bounce and hit the floor, oh no, did it take out the power, or trip a breaker, oh no. As is 'normal' in these cases it dropped perfectly on to the 2 1/4"x4" copper rails running the length of the building. taking quite a notch out of said rails, and turning the wrench in to a puddle of molten globules flying through the air. The batteries and associated equipment didn't even notice.
Also, back in the day, was disposing of a bunch of retired CRT's, procedure was take to dumpster, and break the nub off the back or the neck to safely pressurize them. Unfortunately I discovered that a CRT can hold quite a charge for a very long time, as I picked one up, and happened to grab on to where the cap would be fitted. Not wanting to drop a very large glass object in the shop, I just stood there as it drained through me. Only a second, kilo-volts at micro-amps, but it was an interesting experience.
