Asbestos materials are only hazardous if they are "friable," which means that
the material can easily be reduced to a powder using only your hands. As I
understand it, OSHA and other regulating bodies do not consider non-friable
asbestos products to be problematic even in the long term. Indeed you can
still buy some types of floor tiles and the like which contain asbestos today if I
understand correctly. For what it is worth, I can't imagine a few floor
tiles, sealed in curatorial bags would be a problem in the long term but this of
course is an opinion and other people certainly will have more knowledge on
this process than I do.
