Alert 98 – 16 Stored Energy Hazards
WHAT HAPPENED:
A rig worker was seriously injured when the cap at the end of a top drive accumulator blew off and struck him. He had been helping another employee remove the cap, unaware that the nitrogen pre-charge in the tube was still active. Because it had not been bled off, the pressure was sufficient to violently blow off the end cap.
