Jim. You should put something like this in your reports.
TILE/LINOLEUM FLOOR: If the existing tile was installed prior to 1980 it is possible the tile and or adhesive do contain asbestos. Lab test is only way to verify asbestos. One alternative recommended by EPA is don't sand or try to level asbestos flooring or its backing. When asbestos flooring needs replacing, install new floor covering over it, if possible.
