||Event: 08/05/1999||Employee Injured When Struck By Falling Steel Column|
At approximately 11:45 a.m. on August 5, 1999, Employee #1, an iron worker, was on the third level of a building under construction. A tubular steel column was being hoisted to the fourth level, where several coworkers were ready to perform the connecting work. The top of the column was cleared and positioned to its connecting point. The bottom of the column, however, was still being raised when it became caught on a beam. The spotter had called to the tower crane operator to stop when the choker parted and the column fell approximately 10 ft to the third level. It struck Employee #1, pinning him to the deck. He suffered ankle and head injuries, and was transported to San Francisco General Hospital.
