ABSTRACT
Perimeter doors should consist of hollow steel doors or steel-clad doors with steel frames. Ensure that the strength of the latch and frame anchor equals that of the door and frame. Permit normal entry/egress through a limited number of doors, if possible, while accommodating emergency egress. Ensure that exterior doors into inhabited areas open outward. Locate hinges on the interior of restricted areas. Use exterior security hinges on doors opening outward to reduce their vulnerability.
