A safety door latch system is presented for a grain bin having a door frame. An inner door is connected to the door frame that is configured to move between an open position and a closed position. An outer door is connected to the door frame and is configured to move between an open position and a closed position. A safety mechanism is connected to the door frame and is configured to move between an open position and a closed position. When the inner door frame is moved to a closed position, a portion of the inner door engages the safety mechanism thereby causing the safety mechanism to move to the closed position. When the safety mechanism is in the closed position, the outer door may be latched to the safety mechanism. When the safety mechanism is in the open position, the outer door cannot latch to the safety mechanism.

A roof vent system for a grain storage device is disclosed. A roof vent including a lid is operatively connected to the roof panel adjacent the opening. The lid is configured to move between an open position and a closed position. A bias member configured to apply an upward bias force to the lid to automatically move the lid to the open position. A control lever that is movable between an upper position and a lower position. The control lever is operably connected to the lid by a pull. When control lever is moved to the lower position with a force greater than the bias force of the bias member, the lid is moved to the closed position. A sealing member attached to the lid is configured to provide a seal between the lid and the roof panel when the lid is moved to the closed position.
