with new cannibalized parts. A container that has been drilled immediately adjacent to or through the dial ring to neutralize a lockout should be restored in the following manner: The replacement lock is equal to the original equipment; the drilled hole is repaired with a tapered case-hardened steel rod with a diameter slightly larger than the hole. The outside of the drawer must be puttied, sanded, and repainted so no visible evidence of the hole or its repair is noticeable. SAFEGUARDING LEARNING OBJECTIVES: Explain the procedures for safeguarding classified information. Explain restricted area, the care of working spaces, the care to be taken during working hours, and security checks to help safeguard classified information. Classified information or material will be used only where there are facilities, or under conditions, adequate to prevent unauthorized persons from gaining access to it. Where possible, classified holdings will be consolidated to limit the area where they will be used. Anyone who has possession of classified material is responsible for safeguarding it at all times, and particularly for locking classified material in appropriate security equipment whenever it is not in use or under supervision of authorized persons. The custodian must follow procedures that ensure unauthorized persons do not gain access to classified information by sight or sound or other means. Classified information will not be discussed with or in front of unauthorized persons. A custodian will not remove classified information or material from designated office or working areas except in the performance of his/her official duties and under conditions providing the protection required by OPNAVINST 5510.1. Under no circumstance is a custodian to remove classified material from designated areas for the purpose of working on such material during off-duty hours or for other purposes involving personal convenience unless specifically approved by the Chief of Naval Operations, a fleet commander in chief, the commander of the Naval Space Command, the commanders of the Naval System Commands, the Chief of Naval Research, the Commandant of the Marine Corps, or the Commanding General of Fleet Marine Force Atlantic or Pacific. Approval will be given only when there is an overriding need; when the required physical safeguards, including a GSA-approved container, are met; and when a list of all the material removed is kept at the command. RESTRICTED AREAS Depending on the nature of the work, information, equipment, and material concerned, different areas within a command may have varying degrees of security. To meet this situation, the command should apply different protective measures. To provide for an effective and efficient method to restrict access and to control movement where classified material is stored or used, such areas will be designated Restricted Areas and only those persons whose duties actually require access and who have appropriate security clearances will be allowed freedom to move within the area. Persons not having the proper clearances may, with appropriate approval, be admitted into an area, but they must be controlled by an escort. Restricted Area warning signs will be posted at all normal points. When a language other than English is prevalent, warning signs will be in both English and the local language. CARE DURING WORKING HOURS During working hours, precautions should be taken to prevent access to classified information by unauthorized personnel. Among the necessary precautions to be followed are the following: When classified documents are removed from storage for working purposes, they are to be kept under constant surveillance, face down or covered when not in use. Cover sheets will be Standard Forms 703, 704, or 705 respectively, for Top Secret, Secret, and Confidential documents. Classified information will be discussed only when unauthorized persons cannot overhear the discussion. Particular care should be taken when there are visitors or workmen present. Escorts should alert fellow workers when visitors or workmen enter the space. Drafts, carbon sheets, carbon paper, typewriter ribbons (one-time), plates, stencils, stenographic notes, worksheets, and similar items containing classified information are either destroyed by the person responsible for the preparation of material after they 11-11
