Doors and hardware must conform to use and location requirements. The use of hinges with non-removable pins and strike plate covers reduce the potential for forced break-ins. Wire-glass openings should be used for visibility in fire rated doors along main egress routes. Kick-plates should be provided for classroom, assembly, and circulation doors.
It is important that when the door is being opened it does not obstruct the circulation path. It should be in a recess that is chamfered and top lit so that there are no dark corners, or it should swing a full 180 degrees.
The use of multiple sets of doors to create vestibules can help reduce heated and air conditioned air loss, as well as increase security. Lighting the vestibule at night illuminates someone trying to break through the second set of doors.
