The injured employee was aligning a crane girder at the gas compressor building using a 10-ton hydraulic ram and three steel wedges. The employee was removing the last wedge using an 8-pound sledgehammer as another employee stood on the concrete off to the left side holding a tool tether attached to the wedge with python tape. As the injured employee was backing out the last wedge from the right side via a sledgehammer, the wedge unexpectedly came out from in between the column and the shim, striking the injured employee on the lower left leg and fracturing it.
