186 CHAPTER VI, SECTION 1 CHAPTER VI TEST OPERATIONS AND ROLL-UP SECTION | TEST OPERATIONS AND ROLL-UP On 15 April 1956, the operational phase of REDWING commenced when the Commander of JTF-7 assumed control of all operational activities in the Forward Area. On 25 April 1956, Support services rendered during REDWINGconsisted of supplying materials or labor the initial event (LaCrosse), which was to be executed two days in advance of the scheduled target date of 1 May 1956. All scientific stations work involved was of minor magnitude, but a directive was issued covering preparations for and facilities were readied by this new target date; however, the test was not held until 5 May 1956 due to weather and other technical considerations. The schedule of the 17 events in the REDWING Operation is indicated in Figure 1-4 Chapter I. The last detonation occurred on 21 July 1956, and CJTF-7 relinquished operational control of the Forward Area on 10 August 1956. To ensure adequate support to the various agencies involved in the test operations, the Contractor was responsible for the performance of the following tasks: (1) complete the con- struction of scientific structures and facilities which were held in abeyance until the execution of certain events; (2) provide support personnel, material, and equipment to assist in instrumentation and the recovery of scientific data; (3) adjust camp facilities and services according to the fluctuating population; (4) take measures for minimizing the effects of blasts, thermal energy, inundation, and radioactive contamination for the facilities, equipment, and supplies under Contractor custody, and provide like services for other participating agencies as approved by the AEC; (5) return surplus equipment, construction and materials to Elmer; (6) evacuate personnel from designated sites according to plan and at specified times, and maintain an accurate on a continuous basis; (7) muster account arrange for the evacuation and protection of pets; (8) employ proper measures to safeguard classified material from the evacuated sites; (9) ensure a continuous unattended operation of designated utilities for the various detonations; (10) arrange for rapid re-entry and re-establishment of the vital services at each evacuated site taking into consideration possible shot postponements and Rad-Safe requirements; (11) maintain the capability for operation from bases afloat, including the use of houseboats; (12) and establish safety precautions for glare, fallout or shock waves and the alert signals used for possible evacuation. and equipment to perform whatever work was required by test participants in preparing facilities for the various events. In general, the because each detail of the complex test technique was important, the men, equipment, fabrication, and materials furnished were a high priority concern of Management. The services were authorized by a work order directive from the Manager, EBO, at the request of a participating agency. These directives covered supplying construction equipment, skilled workers, shop re- pair and fabrication, post-test recovery and damage repair surveys, decontamination, button- up services for stations not participating in a scheduled event, and packing, crating, and ship- ping. Support services pyramided considerably in contrast to previous Operations due to the increased scope of the over-all test program and the services involved in ‘‘buttoning-up” various stations for protection against fall-out, blast, and inundation to ensure readiness for succeeding events. Approximately one month prior to the initial event, a planning guide was issued which covered the proposed condition of readiness for each camp in successive events. This guide designated whether the camps wereto be rolled-up, or left intact but evacuated, and also covered the disposition of personnel and equipment. A requirement of CJTF-7 from each Task Group was the preparation and submission of a check list covering duties to be performed for each event during the period of D—5 through D+3. These check lists covered major events and indicated when facilities could be secured and equipment moved, and which utilities were to be serviced for operation during shot time. The lists served as a guide to ensure that the activities of all participating units during that period were compatible with available support and consistent with authorized Rad-Safe procedures. From these lists, summaries were prepared of special helicopter and boat missions, support requirements, trailer and vehicle evacuation schedules, and communication checks. The summaries facilitated the planning for and the exe- cution of the duties assigned the Contractor for placing all facilities in a state of readiness for each detonation. Page 6-1
