Wow! That's sad. And scary.

The closest call I ever had was years ago with a 7-inch air powered angle grinder. I was grinding on something for my '31 coupe. It was just below waist level and I was wearing a baggy old tank top. The wheel caught my shirt tail and wound it up all the way to my stomach. Fortunately, the sudden movement jerked my finger off the trigger and the shirt stopped the wheel just as it contacted bare skin. All I got was a raw abrasion about 3 inches long and a half inch wide and a shredded shirt. If it had been the more powerful electric grinder it probably would have disemboweled me. Lesson learned; when I'm using a grinder now I make sure my shirt tail is tucked in or at least not near the grinding wheel.
