Isn the glue more of a hazard than the tile with asbestos tiles?
In my professional opinion, the mastic is less of a hazard than even the non-friable tile. The asbestos is encapsulated in a tar-like substance, thereby minimizing any likelihood of friability. Unless the mastic is dried-out (and potentially friable) the mastic shouldn’t be a concern. Call Physical Plant Services for an exposure assessment if you have any questions about a particular area.
