CHAPTER VII, SECTIONS 1 and 2 Due to the extent of the ultimate contamination, a heavy work load was imposed on the Rad-safe Croup and there were times when the evaluation of the film badges was not completed until concern beeause of the always-present problem that these emplovees maght claim damages based on such overexposure. were detanted te work ia contaminated areas integration exposure. Because of this fact, several of the Contractor's personnel received cumulative do- personnel period. None of these overexposures Were ex: cessive to the point of impairment of health. Nevertheless, it) was the cause of considerable spirit of the various components of the Task Force. several davs atter exposure.

The term “roll-up” is apphed to the salvaging of all supplies, facilities and equipment at the close of a test operation and putting same in such a state of repair and preservation that only minimum maintenance work wil he necessary until re-use is required. At the ciose of one test operation, another operation can be reasonably expected: yet dus ta the time element, a complete demobilization must be met. The Roli-Up Services detailed in Job V of Contract AT(29-2)-20 oblivated Holmes & Narver, as the Contractor, to rehabilitate and preserve buildings and structures. and to repair, clean, paint, and preserve hoth mobile and stationary equipment for storage and possinie re-use for future tests. Materials and equipment not required, including User’s gear, are returned to the Z. I. The roil-up commenced when the heavy construction period neared tts end. After the equipment hau served its purpuse, it Was returned to the Elmer hase at Eniwetok Atoll where it was overhauled, sandblasted and painted fas required), and preservative was applied to moving parts before it was placed in storage Prior to the initial test, the roll-up phase of the Operation began at Bikini Atall. © Con- struction equipment, installations, and stocks of warehouse material, in addition to sctentific trailers and various types cf User equipment, were completely removed from sites Able and Charlie. Only the essentials fo maintain a 7Aman camp were left at site Fox. Many of the Page 7-4 eRe - tame Fox camp buildings were dismantled and different types of stored materials transferred; one Walk-in reeter was left for food storage. and if the demand warranted, was to be supplemented by the site Tare mess tacilities. The removal of equipment or materials trom sites Nan and Tare was not considered necessary. For the orderly accomplishment of the foreguing. a schedule of events was formulated and published. This schedule detailed, for cach of the davs ot 16 mimus five through B minus one, the actual facilities, equipment or stores to be remosed on cach day trom Charlhe and Fox to Tare for transshipment bv larger vessels to Elmer. The issue by TG 7.1 of a schedule for removal of scientific vans and other vehicles was of material assistance in coordinating the Contractor’s andScientific Group's requirements. Reoccupation of Nan, Tare and the reduced camp at Fox had been scheduled after Bravo, and planning tor this period anticipated the eventual use of Nan as a staging area for equipment and supplies which were to be removed from Tare prior to the scheduled Koon event. Consequently. a mole was constructed at Nan for the beaching of LSTs in order to facilitate the final evacuation of Nan. However, due to the widespread destruction and radioactive contamination at practically all sites at Bikini Atoil following the Bravo event, plans for reoccupation were abandoned and all personnel thereafter were quartered on ships Immediately following the Bravo event, notification was received that preparations for the future scheduled Bikini tests would be conducted from aboard ship. In compliance with the new instructions, only those Contractor personnel engaged in recovery and salvage operations were quartered aboard ship for specific work assignments and were under Rad-Safe control.
