At 816 South Figueroa Street, two limited areas were established, a central file room and a communications room because it was considered that most if not all of the Restricted Data maintained by Holmes & Narver, Inc., would be kept at 824 South Figueroa Street, However, the central file room would have classified correspondence and the communications room would handle "Sigtot" one-time tapes classified "Secret," Hense, the two areas mentioned above were established, Admittance to these areas was monitored by the clerks on duty and was confined to only those "Q" cleared personnel who required access to the areas in line of duty. In addition, at 816 South Figueroa Street, additional physical con trols were set up. A 24mhour, 7 days per week guard control was established, During office working hours, one guard was posted at the main entrance as a receptionist-informationist and another acted as general supervisor of guards in both buildings, This guard also acted as a courier to the Navy Headquarters at Long Beach, the Army Communication Center in the Federal Building, and the Los Angeles AEC Security Office; did finger printing, photography, and badge laminating; burned classified waste; changedfile and safe combination as necessary; and did other work incidental to the activities of the Security Division. During nonworking hours, one guard patrolled the entire building. Eleven Watchclox stations were strategically installed so that complete coverage of the building was given by the guard during his hourly patrols, One-hour heat resistant 3-way combination steel cabinets were installed in the central file room, communication room, and other offices where a small number of classified documents might be temporarily stored. Only those "Q" cleared employees whose duties required such access were given combinations to any of the repositories. Duplicate combinations to these vaults were under the close control of the Security Division. These physical controls have been closely inspected every six months by the AEC Inspection Branch, and have always proved satisfactory. No additional physical controls have been reccamended, HONOLULY The Honolulu office had no special areas. For use in the storage of classified material, it had a large, heavy-welled, 3-way combination steel safe controlled by "Q" cleared personnel. However, except as a repository for classified matter in transit, little or no classified matter was kept there. JOBSITE At the start of the operation and until about November 1, 1950, there were no limited or exclusion areas at the Jobsite. Physical security measures were limited to the provision of adequate storage facilities for classified documents. The storage consisted of 3-way combination safes and file cabinets in buildings secured against unauthorized entry after working hours by screening and locks and bars for doors and windows. by camp police, 7-16 In addition, a system of patrols was maintained
