- Finding type
- vessel_history
- Finding
- NavSource's live MSC-292 page states that the hull was built for Iran: laid down as MSC-292 by Peterson Builders Inc., Sturgeon Bay, Wisconsin; completed 16 May 1962; and transferred to Iran as Karkas (MSC 34). It lists fate unknown and gives 320 t displacement, 144 ft length, 28 ft beam, 9 ft draft, 13 kn speed, complement 50, two General Motors diesel engines on two shafts, two .50-caliber machine guns, and one 81-mm mortar. The page states that no DANFS history is available for MSC-292.

- Limitations
- NavSource is a volunteer secondary compilation, not an official registry or primary transfer record. Its information is adopted only as an archival lead and is corroborated by a second specialist build table (ev-02); the transfer instrument, Iranian commissioning record, hull material, launch date, and final disposition were not located. Contains no asbestos information.

- Finding
- The Peterson Builders build table independently lists 'MSC 292 | Karkas (M 34) | Iran | Coastal Minesweeper | 390d | 145 | 16-May-62,' corroborating the builder, Iranian recipient, name/pennant, vessel type, and 16 May 1962 date reported by NavSource.

- Specialist secondary industry compilation, not an official Navy, Iranian, or shipbuilder archival record. Its 390d/145 figures differ from NavSource's 320 t/144 ft, so those figures are not silently reconciled or carried as definitive. Contains no asbestos information or proof of the transfer mechanism.

[4]U.S. Government Accountability Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct. 18, 1979) [gao]
- Locator
- GAO product page highlights; report enclosure I as indexed by GAO search (direct PDF fetch returned HTTP 403 this session)
- Finding type
- gov_survey
- Finding
- GAO documented Navy asbestos-insulation policy and stated that the Navy's 1975 policy removed and replaced with nonasbestos materials only insulation that was damaged or had to be removed for necessary repairs. The report's full-text search extract says insulation specifications began seeking little or no asbestos as early as 1971, were changed to asbestos-free by late 1973, and that existing asbestos products remained in warehouses, shipyards, and aboard ships. MSC-292's 1962 completion predates those changes.

- Limitations
- Program-level official documentation, not a record for MSC-292, Peterson Builders, or Iranian Navy service. It supports an era inference only and does not establish any asbestos-containing product aboard this hull, quantity, exposure, or current condition. GAO fieldwork concerned Long Beach and Norfolk Naval Shipyards, not the builder.

[5]Batch-7572 search ledger: NHHC DANFS candidate page; NavSource MSC-292 page/index; Peterson Builders build table; NARA Catalog; Naval Vessel Register; GAO; CourtListener authenticated helper; secondary web sweep [other_primary]
- Locator

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the public authoritative sources searched: no asbestos survey, abatement contract, hazardous-material disclosure, work package, or official Iranian service/disposal record for MSC-292/Karkas was found. CourtListener is not included in that negative result: every required authenticated helper query was blocked by the fleet's exhausted daily quota (about 5.4 hours until reset), so litigation remains unsearched. Secondary web results supplied no qualifying asbestos case and no authoritative hull-specific asbestos documentation; marketing and forum material were excluded.

- Absence of a located public record does not prove absence of asbestos aboard. The CourtListener sweep is a real open gap, not a no-result finding. Undigitized leads include the U.S.-Iran transfer instrument, Peterson Builders construction records, Navy Bureau of Ships material specifications, Iranian Navy service/refit records, and disposition records.

[6]Status correction synthesized from NavSource MSC-292 page and ShipbuildingHistory Peterson Builders table [other_primary]
- Locator
- NavSource 11/05292.htm timeline; ShipbuildingHistory Peterson Builders MSC 292 row
- Finding type
- historical_record
- Finding
- CORRECTION: MSC-292/Karkas was not a commissioned USS vessel. The located hull sources describe it as built for Iran and transferred on completion as Karkas (MSC 34); neither source reports U.S. Navy commissioning or a U.S. service period. The project-list label 'USS Karkas (MSC-292)' therefore must not be read as a historical service designation.

- Limitations
- Corrects a naming/status attribution, not a material claim. The conclusion relies on two secondary compilations because no official U.S.-Iran transfer instrument or Iranian commissioning record was located; it does not establish the legal transfer mechanism or whether the United States retained registry title after transfer.

[7]Era inference based on MSC-292 diesel specification (NavSource) and GAO HRD-80-2 Navy asbestos-policy record [gao]

- Finding type
- asbestos_application
- Finding
- A diesel-powered coastal minesweeper completed in 1962 falls within the documented Navy asbestos-use era. For a diesel vessel of this period, era-standard potential applications are engine and diesel-exhaust lagging, gaskets, valve packing, and electrical insulation. The listed diesel propulsion means there is no boiler or steam-line lagging pathway.

- Limitations
- Class/era inference only. No hull-specific insulation survey, material list, construction work package, manufacturer identification, or Iranian refit record was located. The NavSource diesel specification is secondary, and GAO is a Navy-wide program source; neither establishes that any listed material was installed aboard MSC-292/Karkas, its quantity, exposure, or present-day status.

- Finding
- NIOSH conducted a walk-through industrial-hygiene survey at Peterson Builders Inc., Sturgeon Bay, on 15 December 1978 for an epidemiological study of painting trades and paint-material hazards. The catalog record identifies the builder as SIC 3731 (ship building and repairing).

- Limitations
- Federal yard-level occupational-health record, not a hull record. Its stated subject is paint-material hazards and the catalog record contains no asbestos finding. The survey was sixteen years after MSC-292's completion, so it does not establish construction-era conditions, asbestos use, exposure, or any material aboard this hull.
