[1]U.S. Government Accountability Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (1979), report overview and policy summary. [gao]
- Locator
- Report overview; scope is Navy ship asbestos and Long Beach/Norfolk shipyards, not LSM-492.
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, abatement record, hazmat disclosure, or asbestos litigation record for LSM-492 was verified in the sources accessible during this research. Official Navy-wide and shipyard sources document asbestos use in Navy ships and shipyard work, but they do not establish asbestos aboard this hull. Ship-specific asbestos documentation remains unknown.

- Limitations
- This Navy-wide report establishes historical asbestos use and policy in Navy ships at a program level only. It does not name LSM-492, its class, builder, systems, maintenance history, or crew. It cannot support a finding that asbestos was installed aboard this hull or that any person was exposed.
