I don’t think that would be a hazard. Mechanical abrasion is what makes it friable. Even if it’s uncovered, I don’t think vacuuming would release the fibers from the tile. That’s my unscientific opinion. (I also used to do asbestos abatement.)
P.S. does anyone other than me put a disclaimer about other products in older homes that may contain asbestos, such as stippled ceilings?
Everyplace I know of requires you to be licensed to take samples OR tet this. Therefore I state something like this:
There was a possible ACM (asbestos containing material) at the floor tiles. To verify this, you would need to have further evaluation and testing done by a licensed and competent asbestos specialist. Asbestos can be hazardous to your health under certain conditions.
There was possible ACM (asbestos containing material) present. A visual home inspection can not determine the absence or presence of asbestos. Asbestos content can only be determined by laboratory analysis.
It is sometimes found on older plumbing pipes, heating ducts, boilers, floor tiles or other building materials. To verify this, consult with a qualified asbestos specialist. If ACM is present it is often removed or encapsulated.
Possible asbestos (vinyl flooring)
Vinyl flooring in the home appeared to have been manufactured during a time period during which it was common for this type of flooring to contain asbestos.
In its friable form (in which fibers may be released into the air and inhaled) asbestos is a known carcinogen and a cause of asbestosis. This flooring should not be removed without proper precautions.
Confirming the presence of asbestos requires testing by a qualified laboratory.
The Inspector recommends contacting your local health department for help in deciding on the best course of action.
*The floor tiles in the xxxx are similar in appearance to those containing asbestos. Laboratory analysis is required to confirm the presence of asbestos, however, asbestos-containing materials of this type were in common use around the time that this house was built. When asbestos containing tiles are in good, undamaged condition, and when it is found in an area not subject to mechanical damage, current advice is to leave this material alone (EPA). Asbestos tiles in poor condition (flaking, or mechanically damaged) should be removed and properly disposed of by an asbestos abatement professional. Removal should never be attempted by the homeowner. *
