Alert 01 – 42 Energy Isolation – Top Drive Repair Traps Fingers
WHAT HAPPENED:
While tripping in the hole, a keeper pin to the grabber heads was on the rig floor. During the keeper pin replacement, it was decided to replace the grabber heads and preparations were made to access the heads. While removing the heads from the barrel of the grabber, the retractor piston unexpectedly moved from stored energy, trapping the floorman’s hands between one of the heads and the grabber barrel severing one finger, two finger tips and badly crushed another finger.
