Abstract: At approximately 7:15 a.m. on September 5, 1997, Employee #1 and coworkers were lowering a bent to remove the falsework. Two hydraulic jacks, one under each end of the bent, were used to jack up the bent so that supports from under the bent could be removed and the bent could be lowered down. During this operation, the bent slipped and moved off the hydraulic jacks causing the bent and the falsework to collapse. While running for shelter, Employee #1 was struck by a falling 12-in. by 12-in. post. Employee #1 was taken to Washington Hospital in Fremont, where he was diagnosed to have sustained leg wounds and fracture injuries.
