- Finding
- NHHC identifies Avoyel as a Navajo-class fleet tug, built at Charleston Shipbuilding & Drydock Co.; laid down 1944-03-25, launched 1944-08-09, commissioned 1945-01-08, redesignated ATF-150 on 1945-05-15, and lists a complement of 85. It records wartime Pacific towing, a 1946 Guam repair-and-alteration period, Navy decommissioning into reserve on 1947-01-11, a Coast Guard loan on 1956-07-09, Navy List striking and permanent Coast Guard transfer on 1969-06-01, and Coast Guard decommissioning, sale, and commercial service after 1969-09-30.

- Navy complement 85 (listed particulars)
- Limitations
- Establishes identity and historical movements, not onboard material content. Its complement of 85 differs from the Coast Guard history's 76, likely reflecting different service periods; the reason is not documented. The post-sale fate is not supplied.

- Finding
- U.S. Coast Guard history identifies the same hull as AT/ATF/WAT/WMEC-150, records Coast Guard commissioning on 1956-10-03 and decommissioning on 1969-09-30, and lists four General Motors diesel engines powering four Allis Chalmers generators and four electric motors, a single propeller, 3,000 brake horsepower, and a complement of 76. It states that the ship served at Eureka and then Fields Landing, California, before sale into commercial service.

- Coast Guard complement 76 (listed particulars)
- Limitations
- The Coast Guard history supplies cutter-era particulars and paraphrases the earlier Navy history. It contains no asbestos inventory or survey. The 76-person complement must not overwrite the Navy-era DANFS figure of 85.

- Shipbuilding and repairing—historical contact with asbestos in shipyard work
- Finding type
- asbestos_application
- Finding
- OSHA's 1994 asbestos rulemaking describes extensive use of asbestos products on American ships from the early 1940s through the late 1970s, including joiner bulkheads, insulation on steam and hot-water pipes, boilers and tanks, ceiling tile, and fire-resistant bulkhead sheets. Avoyel was built and served during that era, but OSHA does not identify this tug or its installed materials.

- Early 1940s through late 1970s
- Population
- American shipbuilding and repair workers generally
- Limitations
- General American-ship era evidence only. Avoyel was diesel-electric, so the rulemaking's steam-pipe and boiler examples cannot be inferred for its propulsion plant. This row establishes no asbestos presence, product, quantity, exposure, or causation aboard Avoyel.

- Finding
- NARA Special List 44 indexes Avoyel (ATF-150) Navy deck logs dated 1945-01-08 through 1945-06-30. NARA explains that deck logs can narrow major-work dates but do not directly identify asbestos aboard a vessel.

- historical_record
- Finding
- NARA identifies RG 19 Bureau of Ships correspondence, ship specifications, and hull-series engineering drawings—especially filing codes S39 (insulation and lagging) and S48 (piping)—as research paths for vessel material identification. These are leads for Avoyel construction and the documented 1945, 1946, and preinactivation yard periods; no Avoyel-specific specification or drawing was retrieved.

- Finding
- No ship-specific asbestos survey, abatement record, or material specification for Avoyel was located in the NHHC, Coast Guard, NARA, OSHA, and NAVSEA public sources searched in this batch. This is a limited negative search result, not evidence that the ship lacked asbestos.
