Abstract: A door assembly includes a barrier door that is hingedly rotatable about an axis of rotation. The door assembly further includes an environmental door that is hingedly rotatable about the axis of rotation. The barrier door and the environmental door can be rotated independently or in unison from opened positions to closed positions. The barrier door has a handle and the environmental door has a hole through which the handle can pass so that the barrier door handle can be accessed through the environmental door. The environmental door also has a cover for selectively closing the handle hole.
