CHAPTER 7.3 PHYSICAL SECURITY At the beginning of the operation, physical safeguards for Holmes & Narver, Inc, premises were below AEC security requirements, Therefore, in order that the company could maintain and store classified documents and material and in order to set up a limited area for classified AEC work, it was necessary to establish physical controls which would conform to AEC General Manager's Instructions No. 37, covering the handling, transmittal, and storage of classified matter and No. 60 (later No. 153), covering AEC physical security standards. These latter instructions took into consideration the scope of physical security in proportion to length of contract, highest classification and quantity of documents or work which would be involved, and type of security areas which would be necessary for proper progress of the work. HOME OFFICE It was determined that the establishment of a limited area at 824 South Figueroa Street would be adequate for the engineering operation, This type of area is defined as an area in which uncontrolled movement would permit access to classified matter but in which access could be prevented by escort and by other internal controls. Safeguards would be more rigid than in a controlled or restricted area and not as rigid as in an exclusion area. Accordingly, a 24-hour, 7 days per week guard control was set up at 824 South Figueroa Street, attended by General Plant Protection Company's trained guards, all of whom had been granted AEC "Q" clearance, A Watchclox system of area patrol was installed, certain physical barriers were erected, and a communication system was established for guards to phone or receive phone calls from their control at General Plant Protection Company's main office. For entrance control, an identification badges was issued to each AEC "Q" cleared person requiring access to the limited area, These badges, closely controlled by the Security Division, were tamperproof plastic and showed the person's photograph, number, physical description, a signature, and a counter-signature by the Chief or Assistant Chief Security Officer. Badges were worn by employees entering, working in, or leaving the limited area, and close scrutiny of these badges was made by guards at the entrance to the area, No person without an AEC "Q" clearance and without an identification badge was admitted to the area, In conformance with requirements of AEC General Manager's Instructions No. 37, "Storage of Classified Matter," there were at 824 South Figueroa Street adequate 3-way combination steel repositories meeting AEC specifications. 7-15
