Abstract: At 11:30 a.m. on January 5, 2004, Employee #1, a mechanic, worked on a garnett machine Number 3, at the Prison Industries Authority mattress refurbishing plant at San Quentin Prison. Employee #1's job was to enter the unguarded area inside the fence to stick the expanded cotton to direct it up the conveyor. He opened the perimeter guard fence and went inside the guard to perform this task using a wooden handle. Upon completion, he turned and started walking out. He tripped on a shaft across the pathway and started falling forward. He stuck out his hand to stop his fall, and his right index finger went into a pinch point between a chain and sprocket drive on the machine, which was in operation at that time. His finger was amputated down to the base knuckle. Employee #1 was hospitalized.
