Abstract: On September 24, 2007, Employee #1 and coworkers were dismantling an old conveyor house between two buildings. All unnecessary components had been removed, leaving only the main frame, which was secured and stabilized with 1 in. steel cables reinforced with turn buckles and cable clamps. A coworker had cut four corners out of the 6 in. angle iron to the structure when, after making the final cut, the structure pulled loose from the building to which it was attached and collapsed. Employee #1 and two coworkers were on the structure, approximately 70 ft from where the cut was made, and fell with it. All sustained injuries but Employee #1 developed a blood clot and was placed on life support. He died approximately four days later when life support was disconnected.
