4.3 Roll-up After the final shot, most of the work will involve data re- duction, packing of materials and equipment, shipment of samples, and the writing of the preliminary test report. All records and classified material will be cleared through the appropriate channels and prepared for trans- mittal to USIRDL. Special details of roll-up operations may be required. Regarding washdown, if after the last shot, surface surveys indicate a pattern of residual activity, then a detailed check of water coverage by the washdown system on the test areas will be attempted on Transit Able. Consideration will also be given to the possible need for industrial decontamination of one or both ships before, or during, their return to the continental United States. The scove of such work and the logistics involved will be ascer- tained when final tactical decontamination in the field has been completed. Aviation mcintenance personnel will complete any required maintenance on the aircraft and prepare them for shipment aboard Able and Baker. Post-test work at the Laboratory will include data analysis, samsle analysis, and the writing of the final report. 4.4 Logistics and Support Services 4.4.1 Equipment Required Detailed lists of equipment required for rroject 6.4 are given in the Annexes and Tabs of the sub-projects.
