Worker Struck By Pipe Wrench Safety Alert
$0.00
A service rig crew member removed the last drill collar and installed a lift sub using a pipe wrench. A worker installed the sub and fisherman then operated the power tongs to allow the tightening of the lift sub’s remaining threads. At the same time, another crew member released winch controls, which redirected all hydraulic power to the power tongs and revved the engine. The extra engine capacity in the power tongs spun the equipment and attached pipe wrench into the fisherman. The impact threw the fisherman several feet, he was immediately transported to the hospital.
