There's a fact on that website, that I beg to differ with.
It states there, that Alternating current is 3 times more dangerous (shock-wise) than Direct current.
I would say that DC would be more dangerous,
because it has no "Current-Zero", and AC has a habit of throwing people away from contact, whereas with DC, your hands clench, and that's where they stay.
Also, I don't know where they got the arbitrary number of 3 from?
What are your thoughts on this?.
