A ponytail or hair net would have prevented it.
I had a new hire get is hand all busted up because he wouldn’t listen when I told him “DO NOT WEAR CLOTH GLOVES!!!!!”. We had a wire brush in a drill press for buffing the inner diameter of a part. I even showed the kid that the brush would grab a cloth glove the way it wouldn’t grab leather or a bare hand.
I think shop classes need a safety video of some unfortunate person getting chopped to bits to clarify any doubt about following safety procedures.
On www.darwinawards.com, there are loads of these unfortunate cases.
I read about some unfortunate kid, whose job was to chop up ice blocks for fishing boats. He had been told explicitly to not touch the remnant that would be left at the end of the day, as for it was only a few pennies worth.
At the end of one shift, the remnant ice block got the better of him and he ever-so-carefully attempted to nudge the remnant through. Unfortunately, the ice chipper grabbed him and it cost the boat owner $30,000 to clean the boat.
