Rigging employees were setting a pipe that was 20 feet long, 24 inches in diameter, and weighed 5 tons. As the load was being transferred from the crane to the rack, the riggers were adjusting the chain fall hoists. Slack was taken up in one of the hoists, which caused the pipe to lift. When the pipe lifted the injured employee was straddling the beam, and the shoe plate of the pipe contacted the injured employee's left lower leg, causing a compound fracture. The employee was admitted to the hospital for surgery.
