Had a good day piping up some 10 ton AC's for another Co. Bumped my forarm at 10:30 on a 4x4 elec. box cover and dam. 7 stitches. They need to take the sheer edge off of stuff. I didn't know it was cut until I looked. Lost 10 mins. dressing it but finished most of the piping before I left for the ER at 4:00. Got the same Dr. that sewed my forehead up last summer. Good bunch of folks. Be careful out there guys.
