I have just had some asbestos removed from my new [uninhabited as of yet ] home, it was extremely pricey to remove. The company warned us that floor tile contains asbestos but said that it was 'low risk' and to just wear a mask during removal. However, I did rip it out [ with a mask ] but am worried about the grey paper like residue left sticking to the hardwood. Is this something dangerous? It looks as if contains wood fibers.
