- Finding type
- asbestos_application
- Finding
- An EPA study summary reports that a factory was established to supply asbestos insulation for pipes, boilers, and turbines of U.S. Navy ships during World War II. This is general historical context; it does not identify LSM-225, an LSM class vessel, or material installed aboard this hull.

- Population
- U.S. Navy shipbuilding and shipboard context during World War II
- Limitations
- The cited summary documents Navy-directed WWII asbestos insulation production in general. It does not establish a specific product, machinery arrangement, or asbestos-containing component aboard USS LSM-225; no installation, quantity, location, condition, exposure, or causation finding is made.

[3]U.S. Government Accountability Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct. 18, 1979) [gao]

- Report highlights and full report, 26 pp.
- Finding type
- gov_survey
- Finding
- GAO's 1979 review describes Navy asbestos use in ships and Navy policies for insulation removal and replacement, including a policy modified in 1979. The report's product summary does not identify LSM-225 or establish what material was present aboard it.

[4]National Archives, Researching Asbestos aboard US Naval Vessel up through 1961 [other_primary]
- Locator
- Beginning Research; record-series descriptions for S39 and S48
- Finding type
- historical_record
- Finding
- NARA's guide for researching asbestos aboard U.S. naval vessels identifies S39 insulation and lagging and S48 piping records as research paths, while cautioning that standard engineering drawing series do not directly establish asbestos presence. The public NARA ship-plan and deck-log indexes reviewed did not yield an LSM-225-specific asbestos record.

- Researchers of U.S. Navy vessels through 1961
- Limitations
- This is an archival research guide, not a hull record. The indexes are not comprehensive; relevant files were not requested or reviewed in person, and the lack of a public index hit does not show asbestos was absent.

- Finding type
- historical_record
- Finding
- The live NHHC United States Pacific Fleet Organization, 1 May 1945 record reviewed does not list LSM-225. This source review found no hull entry there; the omission does not establish the vessel's service, assignment, or absence from the fleet at other dates.

- Limitations
- A single fleet organization list is a dated snapshot and is not a complete vessel history or comprehensive assignment register. Non-listing does not establish that LSM-225 was not in service or assigned elsewhere.
