Suicide prevention? Maybe I'm missing something. I just turn the power off when messing with anything electrical. Easy peasy.

In a telephone company central office we didn't have the option to turn off the power, you worked with a live bussbar all the time. Have you ever seen what a 1,000 amp 48 volt supply can do to a screwdriver? (yes, that is one thousand amp. some larger ones were four thousand amp.)
