I did this yesterday when I was using an imact swivel and socket on my impact wrench. The thing on the wrench to hold sockets on is broken, so they can fling off real easy when the imact is turning. I was only about a foot from the impact wrench and the swivel and socket flew off when I was under the rear of the 'Burb. It hit me in the head, then bounce off and landed a few feet in front of the truck. SAFETY FIRST! I'm glad it didn't hit my eye... I would probably be blind now Now there is something else I need safety glasses for.
