I worked daily for about 40 years with table saws, a giant industrial band saw (eight foot long blade) lathes, and Bridgeport mills
I learned my lesson cheaply enough. Working a turret drill press, a drill cutting pealed off what I was drilling, snagged my long sleeve shirt, and dragged me into the spindle. Fortunately, I could reach the power button.
Pure luck, no injury, but it made an impression. I threw away the long sleeve/short sleeve combo shirt.
But chain saws still scare the **** out of me. TWO separate girlfriends have had Dads who stuck themselves in the chest with one. (Both survived, both wore scars)
