Speaking of squished hands.
I was talking to a buddy of mine at an apple packing plant. We were standing outside, where a block long conveyor belt was being operated to take packed apple boxes to another building. I don't really recall the why of the conveyor, but it had about a 1 story tilt in that block long distance, so was tilted. My buddy was lighting his cigarette and dropped his lighter, in such a way, that it fell on to the inside of the conveyor onto the belt about a few feet from the roller. As his lighter was moving toward the roller, he made a grab for it, and got his fingers caught and his hand started to roll up around the drive wheel between the belt. He jammed the motion of the belt and stopped it. I frantically looked for a shut off, found and hit the kill button. I didn't work there, so had no idea where anything was. I was able to pull hard enough in reverse to unwrap his hand. His hand was very flat looking, it looked very strange, but in about a week or so, was back to normal.
