[1]OSHA, Occupational Exposure to Asbestos, final rule preamble (59 FR 40964, 10 Aug 1994) [federal_register]
- Locator
- Federal Register rule preamble, shipbuilding and repairing historical-contact section, lines 1749–1755 in live page text; especially OSHA’s characterization of ships delivered before 1975 (line 1753).
- Finding type
- asbestos_application
- Finding
- OSHA's 1994 rulemaking review states that asbestos products were used extensively on American ships from the early 1940s through the late 1970s, and that OSHA believed ships delivered before 1975 contained extensive asbestos insulation. It also describes exposure opportunities during ship construction, repair, and overhaul. This supports only a broad period-level hazard context for this batch-identified WWII-era hull; it does not establish that USS LSM-217 contained asbestos or that any person aboard was exposed.

- WWII ship construction and ships delivered before 1975
- Limitations
- Class/era context only. OSHA's generalization is not a hull survey, material list, work package, or exposure record for USS LSM-217. Product categories cited in the federal rule are not asserted as installed aboard this hull; material identity, location, quantity, condition, removal, and individual exposure remain unknown.

- Historical narrative, paragraph beginning 'As the world entered World War II'
- Finding type
- asbestos_application
- Finding
- NIOSH's historical account states that the U.S. Navy increased its use of asbestos insulation for pipes in naval vessels during World War II. This supplies historical naval-vessel context only and does not establish asbestos aboard USS LSM-217.

[3]Research finding from public-source searches recorded in this record's search_ledger [other_primary]
- Locator
- Search ledger entries sl-uss-lsm-217-lsm217-03 through -05
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos litigation record was located in the accessible searches completed for this record. CourtListener litigation searches for the exact ship name and hull number were not completed because its authenticated fleet limiter denied the first request before a result was returned. This is an incomplete search, not a CourtListener no-result finding.

- Limitations
- Negative finding is strictly limited to accessible non-CourtListener searches. Litigation status remains unresolved because authenticated CourtListener searches by exact name and hull number were not completed; do not interpret this as absence of litigation or an adjudication about exposure.

- Sections on RG 19 ship engineering drawings and hull-number arrangement, lines 499–508; especially Ship Engineering Drawings (1874–1976) and Microfilm (1945–1955).
- Finding type
- historical_record
- Finding
- NARA identifies Bureau of Ships RG 19 ship engineering drawings, including hull-number-arranged records and insulation/lagging filing codes, as research avenues for ship-specific asbestos investigation. This provides a follow-up archival path for LSM-217; it is not evidence that a responsive LSM-217 record exists or that the ship contained asbestos.

- Archival research guidance only. No LSM-217-specific catalog item or drawing was located in this session; the cited guide does not establish this hull’s construction materials, later condition, or any individual exposure.
