Abstract: At approximately 8:00 a.m. on July 21, 2009, Employee #1 was servicing a Bibko Ready Mix Recycling System, Model Number 2000, Serial Number 907/05, a cement recycler. He asked a coworker to turn the machine off, and the coworker reported that he did that. In order to make a gap adjustment on the screw conveyor, Employee #1 used a pneumatic chipper to remove dried cement from the adjustment bolt. The machine started its automatic cycle, and Employee #1's arm became caught in the screw conveyor. He suffered a deep laceration that required hospitalization for treatment. The equipment had not been turned off and was not locked or tagged out.
