I believe my floor has vinyl/asphalt tiles that contains asbestos. There was a golf ball sized "pot-hole" on the ground. I further damaged it by rolling over it with an office chair wheel, and led to some small pieces to fall off. But this only happened a few times. Aside from that, we did regular wet mopping over the floor.
Yes, I know it wasn’t good, but “non-friable” ACM (asbestos containing material) don't tend to release a lot of fiber when you damage it right? as opposed to say, friable ones like popcorn ceiling or insulation. I just hope that even when I crumbled it with my office chair, most asbestos were still bound up in the flooring material. Maybe some fiber got released but at least I didn't put my nose up to it and snuff it.
Thinking of this from a theoretical standpoint, I guess if I had my windows open and there were air flow, the air current would dominate the movement of the fibers and very little would get to my nose (I was sitting on the chair when this happened). If I had my windows shut, I would how likely it would be for the fibers to diffuse through air and reach my nose. The fibers can be microscopic so I don't know how much gravity would work in my favor...
How worried should I be? Oh well, we are all exposed to small amount of asbestos in everyday life so perhaps this isn't something to worry about?
Thanks
