First thing I was ever taught when I started as a Tech.... PULL THE PLUGS IF ENTERING THE MACHINE.
Circuit breakers have been known to fail.
I know on our old 30's, there was 1 or 2 machines that you could turn all the switches off, and the machine could still come to life, due to one of the relays (from memory PR5) arcing and fusing itself closed.
