A door assembly includes a door frame and a door coupled to the door frame and movable between an open and closed position. The door includes a first surface that faces in a first direction and a second surface that faces in a direction that is greater than 90 degrees from the first direction. The door assembly also includes a securing member pivotably mounted to the door frame and pivotable between a first position, in which the securing member prevents the door from moving to the open position, and a second position, in which the securing member releases the door, wherein the securing member is configured to engage both the first surface and the second surface when the securing member is in the first position. The door assembly may also include a latching assembly mounted to the door frame, wherein, in a first state, the latching assembly holds the securing member in the first position, and, in a second state, the latching assembly releases the securing member to allow the securing member to pivot from the first position to the second position.
