Alert 06 – 33 Dropped Object – Derrickboard Slide Bar Incident


After laying down drill collars, the Derrickman positioned the Slide Bar across the derrickboard “alleyway” and came down to the rig floor. The rig crew and casing crew were rigging up to run casing. While using the rig floor hoist to pull the casing slips up the V-door, the Slide Bar fell from the derrickboard and hit the lay down stanchion (pole) in the mouse-hole. The Slide Bar ricocheted off the stanchion and struck a member of the casing crew in the back of the head, then struck the Assistant Driller in the left calf.
