Abstract: A safety system for reducing the risk of a suffocation accident occurring in a grain bin is disclosed. The disclosed safety apparatus includes an electrical switch in circuit with the motor of an auger mounted in the grain bin for discharging grain therefrom. The switch has a first state wherein the switch prevents operation of the motor and a second state wherein the switch permits operation of the motor. The disclosed apparatus also includes a cover mounted adjacent the access opening for movement between a first position wherein the cover precludes human entry through the access opening and a second position wherein the cover is displaced from the first position. The switch and the cover are positioned to place the switch in the second state when the cover is in the first position and to place the switch in the first state when the cover is displaced from the first position. The apparatus is further provided with a latch for securing the cover in the first position.
