I have a question about aspestos. The basement of my very old house has a white insulation around the pipes that I believe to be aspestos. A long time ago I pulled a sticker off that said it was just that. Can this affect my health in any way? I'm sure I may have bumped my head on the stuff more than once without thinking about it. Also our washer is down there. Can aspestos harm you if you dont disrupt it? It looks to be rotting away in some places.
