On about November 1, 1950, the first exclusion area was set up on Parry Island to provide protection for a scientific laboratory, The group of buildings involved was completely fenced, and night illumination was provided, Access to the area was limited to "Q" cleared personnel required to enter in connection with the work within the area. The area was guarded by military police provided by Commander Task Group 3.2. Entrance was limited to those on an approved list, with identification provided by signature and Navy identification card, Later, in January 1951, AEC identification badges were used. On January 15, 1951, an exclusion area was established on Parry Island to include the main offices of Holmes & Narver, the Headquarters Offices of the AEC representatives, and the Headquarters of the Com- mander Joint Task Force 3, This area was fenced and was guarded by military police, Entrance was limited to those to whom exclusion area identification badges had been issued, Later, additional exclusion areas were established both on Parry and on other islands, The regulations concerning these areas were similar to those previously established for other exclusion areas. When the office exclusion area was established on January 15, 1951, the AEC badge system was initiated. Access to areas of different security importance was controlled by different colored photo identification badges. These badges were produced, issued, and controlled by AEC Security Officers. Also, at this time military police assumed responsibility for the patroling, guarding, and control of all areas, The normal police functions incident to the control of Holmes & Narver personnel remained with the Holmes & Narver camp police force. With the assumption of security control by the AEC, assisted by the military police, the function of the Holmes & Narver Jobsite Se- curity Officer and his staff was largely to render assistance to the AEC security staff in so far as Holmes & Narver personnel were concerned, At this time and for the remainder of the operating period, an important activity of Holmes & Narver security was to insure that Holmes & Narver personnel were kept supplied with the proper badges to permit their access to areas where they were required to perform necessary work and to insure that unnecessary access to security areas was denied. This included preparation of badge requests after careful checking of the individual's clearance and the need for the access requested, In cases where access was requested but the person concerned did not have the proper clearance, it was necessary to arrange for a special pass and the provision of an escort in the area. 7-17
