Abstract: On January 14, 2011, an employee was operating an excavator bucket that was being used to lift and hold two 12 by 12 wooden blocks in place for Employee #1 and Employee #2 to position and nail in place. While holding one of the wooden blocks in place, the two workers stepped under the bucket, bent over and attempted to tap the block in place. The operator was wearing a life vest (PFD) that became twisted. The operator attempted to remove the life jacket (PFD), and one of his arms came in contact with the up/down control level. The bucket was lowered and landed on Employees #1 and #2, pinning them. Employee #1 was killed, and Employee #2 suffered a severe leg injury and was transported to the hospital by Emergency Medical Services (EMS). Employee #2's left leg was amputated shortly after arriving at the hospital.
