Fatal Incident - Safe Isolation failure?

The other approach is to teach every one to work as if  live working all the time, and avoid two hand contact as much as possible, and to connect things with metal before straddling them with the body.  I do recall about 20, no 25,  years ago replacing a light fitting in someones hallway with the fuse in my back pocket, as was typical ‘lock off’ for the fuse-boards of the time. I was both very disappointed and in another way pleasantly surprised when it was all done and I put the bulb into the holder and it came on !! By some remarkable luck, I had neither blown the fuse to the circuit it was actually on, nor given myself a shock. 

I had the doubtful advantage of experience in my dad's workshop where valved things running  with the lids off were quite  normal, and the HT soon taught you not to prod things, and the wisdom of keeping at least one, or ideally two hands behind your back when not required was drilled in at an early age.

If you make things too safe, everyone assumes it is always the case and may become careless.

This does not help the victim in this case, and it may well have been a double fault, such as CPC off and also an insulation fault to case .
