    Finding
    Achomawi (ATF-148) served in Operation Crossroads as a support ship in the Salvage Unit. The Defense Nuclear Agency history records arrival at Bikini Atoll on 26 May 1946, departure on 29 August 1946, decontamination at San Francisco, operational clearance on 6 December 1946, and final clearance on 13 December 1946.

    Finding
    NHHC's Dawson history states that Achomawi (ATF-148) took Dawson in tow for Kwajalein on 19 August 1946 and reached the destination on 24 August 1946. An NHHC New York history assigns Achomawi a different tow beginning 22 August, so the overlapping departure dates remain unresolved.

    Limitations
    The Dawson and New York DANFS narratives place Achomawi on overlapping tows ending at Kwajalein on 24 August. The exact tow timeline requires deck-log verification. Neither narrative establishes asbestos transfer, asbestos work, or asbestos exposure aboard Achomawi.

    Finding
    A War Production Board order effective in 1944 listed ship-use exceptions for amosite woven insulating felt, fireproof insulating board, and flexible amosite pipe insulation, and referred to Navy Specification 17-L-29 for asbestos-fibre electrical insulation. This documents period shipbuilding material categories, not materials installed aboard Achomawi.

    NHHC's New York history states that Achomawi (ATF-148) took New York in tow for Kwajalein on 22 August 1946 and arrived on 24 August. NHHC's Dawson history assigns the same tug a different tow from 19 to 24 August; the overlap is unresolved.
