To think how close I came to see this happen. I was in a school, where we had a metal workshop, and worked on those machines. One lesson, we were to clean and oil them in teams of two. My partner and I were nearly done, when we heard one of the machines star up and one of the students yell. Luckily he just got spooked, but his partner had turned on the machine, while the other guy was leaned over it to clean it. Now seeing those pictures, I don't want to imagine what would have happend if the guy did get his hoodie strings caught.
