  2. Metal or metal clad doors utilized on entrances to facility.
  3. Metal or metalclad doors utilized on entrances to facility. Auditor should verify that metal or metalclad doors are utilized to the extent possible at the facility. During operation, such doors should be provided where unmonitored entrances are present in the facility to limit the concern for forced entry. All doors should be in a good state of repair and inspected regularly for integrity of operation. Ideal: Metal or metalclad doors provided on all non-monitored entryways during operation. Metal or metalclad doors provided on all entryways during nonoperation. Weakness: easily penetrable doors utilized on unmonitored doorways during operation or nonoperation.
