Alert 14 – 12 Equipment Shift During Rig Up Results in Near Miss
WHAT HAPPENED:
While attempting to install center steel (spreader beam) during rig up on a box-on-box substructure, the top of the boxes moved away from each other as a crane attempted to adjust a sub half for pin placement. The BOP scaffold, which had been put in place prior to pinning the center steel, was pulled off its track and fell approximately 12 feet (3.7 meters). Two employees were standing at one end of the scaffold. They were wearing their fall protection harness and lanyard and were tied off above their heads to the substructure. The equipment worked as intended; no injuries occurred.
