In reference to your description of the danger of different voltages and frequencies...is it still dangerous (potentially life-threatening) to get shocked outside of these ranges, or do things work out well in the vast majority of the cases? This is new to me, I got a bit curious.
It's not really a question of safe vs unsafe so much as increased danger in that range. Stand in the wrong place at a GW power-plant and you might just end up as a ionized cloud in short order. But, even without massive tissue damage things can still be incredibly dangerous.
