Abstract: At 1:00 p.m. on July 10, 1991, Employee #1, a lumber marker on the #4 line at the Sierra Pacific millwork plant in Red Bluff, CA was straightening a board on the outfeed roller conveyor. His right hand came in contact with an unguarded belt and pulley drive, and the tip of his middle finger was amputated. Subsequent investigation revealed that the belt and pulley guard had been shortened because the guard had interfered with the flow of lumber. This was true of all four lumber lines at the plant. Following the injury, a low profile guard was installed that adequately guards the location. The employer was cited for a serious violation of T8CCR 4070 (a) for unguarded belt and pulley drives.
