Another electrical one
Working live on industrial wiring is one of those things that works alright in in principle but in practice is downright dangerous without a lot of training. Most of the time I've got away with it but the time I didn't, there was a bang about as loud as a shotgun blast and a ball of plasma the size of a pineapple exploded between my hands. Simutaneously (and instantaneously, for you technical types) the C60 breaker protecting the submain operated and pulled out all the lights, all the computers, all the test gear, the whole lot... i was less than popular, and worse, I'd blown the end clean off my best screwdriver. Once more, meh.
