When I was watching this person work the chipper, they stuck their foot inside the chipper entry almost to the blades stuffing branches. I mean to say that their foot was maybe 6 inches from the churning blades that can reduce a 12 inch round branch to wood chips in a matter of seconds. I wanted to say something like ” please be careful” but I did not. I just stood there and recorded the sounds of the chipper working. I guess I would have caught the sound of them going into the chipper.
