Abstract: At approximately 8:00 a.m. on October 24, 2000, Employee #1 was working on a bolt up crew. Employee #1 was bolting up steel beams when he ran out of bolts, stood up and traveled on the top of building steel to get some more. As Employee #1 traveled across the steel, the employer was hoisting a load of 14 sheets of 3-ft-by-25-ft steel pan deck weighing about 2500 pounds. The pan deck was not provided with a tagline to control the load. As the load rotated, the employer did not sound a horn, whistle, or use any other device to warn employees of the approaching load. The unrestrained load rotated into the occupied working space, striking Employee #1 in the back. This blow caused Employee #1 to lose his balance and fall. Employee #1 fell 13.5 ft striking a level of decking and steel, and then fell off the leading edge of that level an additional 12.5 ft to the steel deck. Employee #1 was seriously injured and hospitalized as a result of the incident.
