On September 22, 1989, a grain dust explosion occurred at a grain elevator facility. Two potential sources of ignition were identified. The first being a cover for a tail pulley on a leg was found wedged in between the tail pulley and the leg belting. Since both the cover and the tail pulley are metal, a spark may have ignited dust. The second possible ignition source was a head pulley shaft was found with bluing marks, indicating overheating, and the head pulley shroud also showed signs of heating, and may have been in contact with the head pulley shaft, producing intense heat. This explosion resulted in two employees being killed and three hospitalized with burns.
