I was working about 25 feet away from a large, high-speed surface grinder where someone had forgotten to turn the magnetic chuck on. The wheel exploded and the workpiece went flying, right through a 'Colt' heater hanging from the roof.

Let's say I learned a lot that afternoon and HSE guidance is a minimum standard. So, start with a good grinder and add good guards.... then wear personal protection as well.

You needed to be licenced to fit or balance grinding wheels for those surface speeds, and that was part of the training. It also wasn't a cheapie wheel that went off.
