A couple of years ago, I went to replace a vinyl floor in a basement level bathroom of my house. As I lifted up the old flooring I found the mastic was white with a fibrous look to it. Because my house was built over 20 years ago, I was concerned that I might have uncovered a source of asbestos in my home and just exposed myself to a risk of mesothelioma cancer.
I stopped my project and did some further research. Prior to the 1970's many types of building products and insulation materials used in homes contained asbestos. I used to watch my father, a private contractor, and I remember him using asbestos insulation for a heating pipe inside a wall. That was a long time ago, but the research I've done shows that this stuff is still very much with us as it is often more harmful to have it removed than to simply leave it alone.

This is because material that is more or less "stable" will not release asbestos fibers which means you don't have a significant expose risk. In this situation the risk is actually greater if you try to remove it. Asbestos isn't like radioactive material and isn't going to harm you just sitting there. You need to breathe in the fibers to be at risk.
However, if the asbestos material shows signs of wear or [1] [2] [3] 下一页 |
