    Limitations
    The source is Liberty's operational history, not an Apohola material survey. Presence at a shipyard or alongside another ship does not document asbestos aboard Apohola or anyone's exposure.

    Limitations
    The Navy PDF returned HTTP 403 to direct retrieval; its indexed text exposes the exact row, but the page image could not be checked. 'Rmvl Date' is the table's removal date, not a proven dismantling date. No asbestos or abatement information appears in the exposed row.
