It always amazes me how something as potentially lethal as electricity was
ever allowed to be installed in people's home in the first place.

Especially in the early days of metal fittings and cotton covered wire, and
all those lethal contraptions such as open bar unearthed electric fires!

If H&S had been around back then, would it have ever been allowed to happen?
