Abstract: On August 11, 2012, Employee #1, with California Family Foods LLC, was attempting to clean a magnetic filter located in the conveyor system of a rice mill. The magnetic filter usually went through a self cleaning mode every four hours where an air cylinder moves the round magnetic rods past a series of wipers which cause any metal stuck to them to drop into a catch pan for later removal. As the filter went across the wipers, Employee #1 noticed a piece of wire that was still stuck to the magnet that did not drop off. Employee #1 then reached in to the filter area when he manually ran it through the cleaning mode with an override switch. Employee #1 amputated the tip of his right hand ring finger on the magnet filter between pinch points. Employee #1 apparently did not understand the speed or force in which the filter would return (cycle back) to the run position.
