when taking my asbestos supervisor class I remember Dave at TEI telling me that if you smoke and abate asbestos you are 50% more likely to get lung cancer then the average joe. Meso is extremely rare and very fatal. Only thing you can do to ensure that you "lower" your risk to asbestos diseases and asbestos dust, etc... Is to follow all the safety guidelines and make sure all your employees do. I think everyone alive today has been exposed to asbestos at some point in their lives.
