Precautionary measures must be taken so papersstored in the container will not protrude from thedrawers when they are closed, or cannot be fished outthrough the cleft surrounding the drawers. One methodis the insertion of stiff cardboard, such as a file folder,in a horizontal position above papers filed in the drawer.Storage areas for bulky Secret or Confidentialmaterial must have access openings secured byGSA-approved combination padlocks or key-operatedpadlocks with high security cylinders. If these storagerequirements cannot be met afloat or aboard aircraft,Secret or Confidential material may be stored in a lockedcontainer of substantial metal or wood constructionsecured by an approved GSA combination padlock. Inthis case, the area must be locked when not manned andchecked at least once every 24 hours.NEW STORAGE CONTAINERSNew security containers should not be procureduntil a physical security survey of existing equipmentand a review of classified records on hand has beenmade. It might be determined that it would not befeasible to use the equipment or to retire, return, ordeclassify or destroy a sufficient volume of recordscurrently on hand to make the needed security storagespace available.Only containers that have been approved by theFederal Government as security filing equipment shouldbe procured. Equipment is selected from the NationalSupply Schedule of the GSA following the proceduresoutlined in SECNAVINST 10463.1. Modification of anyequipment that is used to store classified material isprohibited. Exceptions to permit acquisition ofspecial-purpose equipment or to modify filing cabinetsto bar-padlock types suitable for storing classifiedmaterial must be requested from the CNO.A security container records form (fig. 11-1) willbe maintained for each security container used for thestorage of classified material. The container will beinspected each watch.Security containers conforming to Federalspecifications bear a test certification label on thelocking drawer, attesting to the security capabilities ofthe container and lock.NONAPPROVED SECURITYCONTAINERSNonapproved security containers are available inmany shapes and sizes; however, containers of thistype may not be used to store classified material eventhough they may be equipped with manipulationproofor manipulation-resistant locks and have othersecurity and fire protection features.Nonapproved containers used to safeguardclassified material should be replaced by an approvedGSA security container.COMBINATIONSA security container, vault, or storeroom must befitted with a lock that resists opening by unauthorizedpersons. Manipulation-resistant (MR) andmanipulation-proof (MP) locks are tested by theUnderwriters' Laboratory (UL) and must have the ULlabel attached to the back of the lock.Federal specifications governing the manufactureof security containers and security vault doors requirethat the unit be equipped with a top-readingchangeable combination lock that controls the lockingof the container. The top-reading design replaced thefront-reading design to provide increased protectionagainst the combination being ascertained by covertviewing. Combination locks are available with twoforms of combination changing: hand or key.Hand-changing requires removing the wheel pack andchanging the wheel to the new combination.Key-changing requires the use of a key that is insertedinto the lock case, permitting a new combination to beset. The type of combination lock desired should bespecified when ordering the container.The following requirements help ensure theeffectiveness of combination locks:1. Combinations must be changed only byindividuals having the responsibility and anappropriate security clearance.2. The combination will be given only to peoplewhose official duties demand access to thecontainer.3. The combination to a security container ischanged at the time the container is received, atthe time any person having knowledge of thecombination leaves the organization, at any timethere is reason to believe that it has beencompromised, or as a minimum every 24months.In selecting combination numbers, multiples of 5,simple ascending or descending arithmetical series,and personal data (such as birthdates and servicenumbers) should be avoided. The same combinationwill not be used for more than one container in anyone component.11-8
