Asbestos Vinyl Sheet Flooring Backing
I need some risk assessment advice.
I recently moved into a new place and discovered vinyl sheet flooring with some damage, in the basement. Here is an image of it:
I am aware that old vinyl sheet flooring may contain asbestos backing material. Upon close inspection of the exposed backing material (in the areas of the image where the flooring is obviously damaged) I discovered what appear to be fiber bundles protruding from the material - it definitely seems like asbestos to me.
To prevent any further possible release of ACM, I have coated the exposed damage edge of flooring with silicone to bind the material.
I need some risk assessment at how bad this is though. I have only been here for about a month, the landlord has lived here for about 15 years possibly, so obviously this damage was cumulative and occurred slowly, not all at once. Given the extent of the visible damage in the photo, do you think serious contamination is a concern? That area may have been walked on and I am concerned about household contamination from things such as socks touching it and being washed with other clothes, dust tracked through the house, etc. What are your thoughts? This discovery has been quite distressing overall.
The backing material seems quite stable. I touched it with gloves very gently and the fiber bundles seem quite firm. The backing material itself is also well put together and does not fall apart when being touched gently.
Asbestos has to be friable to be dangerous. I would not worry about that little area. If you are that concerned, have it tested.
If it were in my house, i'd lay a rubber door mat or similar over the edge thats getting scuffed up, to stop it getting worse, then leave alone. Or fit a metal transition strip along the edge; don't drill through the vinyl when fixing the strip down.
I reccomend you get someone to get rid of it and fill in the hole with concrete if there's a hole under it. I'm 50 percent sure it's asbestos.
