187 the expected short-term occupancy only. To support scientific groups in the Ursula Complex who were required to work at odd hours, limited camp facilities were established on a barge (Station 12), which was towed to and moored off this site. The Fox and Tare camps were rolled-up prior to the Cherokee and Zunievents, respectively. Prior to the Cherokee event, the possibility of pressures damaging the remaining Bikini Camps (Nan and Tare) was considered remote. The windows and doors of buildings were left open; the sides of all tents were rolled-up; and furniture was moved to the center of tents. The fuel tanks of the power plants were covered with earth. The water towers and generator sheds were guyed with steel cables, using heavy mo- CHAPTER VI, SECTION 1 dictated by predicted effects from that particular test. For example, inundation at Nan was considered quite probable because of the Zuni event; as a protection against inundation, a large area south of the airport was cleared and surrounded by a berm about 4 feet high in which vehicles, vans, and other equipment could be placed. Critical facilities such as the power plant and Station 70 were also surrounded with berms. Protecting Nan against inundation from Zuni was accomplished before the Cherokee event inasmuch as radioactive contamination from Cherokee was possible, thus eliminating the need for performing this work in a contaminated area. Planning for evacuation to sea from Bikini Atoll and for operations from bases afloat in case of unacceptable contamination at the camp sites was initiated early in the program. To meet bile equipment as anchors. Because of size, the mess hall at Nan was shored both internally and externally, and the side panels were removed. Mess hall supplies, utensils, and critical items of equipment were covered with tar- worth and the USS Curtiss were outfitted with additional communication equipment and com off Nan with the exception of three LCMs, 11 DUKWsandthe fuel and decontamination bar- Area. Funds were made available to the USNS Ainsworth for providing mattress pads for use The protective measures employed for each detonation were similar to those accomplished and troop space allocations were made aboard the TG 7.3 vessels in order to accomodate Task Group TG 7.5 personnel during the evacuation paulins. Marine craft were anchored or buoyed ges, which were evacuated to sea. for the Cherokee event with modifications as SHIP requirements for bases afloat the USNS Ains- centers prior to their arrival in the Forward in troop berthing spaces.

Personnel were arranged in Muster Groups consisting of a Group Leader and a unit of men from the same department who were to board the ships simultaneously from the same location. Each group varied in size and contained men with like working schedules who were assigned a specific time for assembly at a des- ignated area. Group Leaders reported to one Muster Officer at each of the off-island sites; at Elmer, one Muster Officer was appointed for each department. When the Muster Officer was satisfied with the accountability of the men under his jurisdiction, he reported to the TG 7.3 Beachmaster stating that the group was ready for embarkation. The Beachmaster controlled the dispatching of boats that ferried be- tween ship and shore. Upon boarding the evacuation ships, each group was checked again. The Muster Officer advised the Task Group Evacu- ation Officer upon satisfactory accountability, who in turn reported to the TG 7.3 Evacuation Officer on board the vessel and to the JTF-7 Evacuation Officer. The evacuation of personnel to sea during Operation REDWINGoccurred at Bikini Atoll only. The capability for emergency post-shot evacuation was also maintained at Eniwetok Atoll. The evacuation plan for Eniwetok Atoll contemplated an accurate and detailed account of all personnel; airlifting employees to Honolulu who had accumulated radiation exposures above 2500 mr; provisions for emergency Page 6-3
