ASBESTOS is nothing to mess with!
I would strongly suggest wearing a mask when handling anything that has the remote chance of containing asbestos. In March of 2009, I lost my brother-in-law to Mesothelioma. It is a horrible disease that has no cure. He was diagnosed shortly after he and my sister returned from their honeymoon. He was an otherwise healthy man in his late 40's. His only exposure to asbestos was during his college years when he worked commercial construction a couple of summers.
He was very fortunate to last 5 years (most people get 2 years if they are lucky) but that was only because he participated in many clinical trials of radical treatments. He went through 5 years of hell but hopefully his participation in the experimental treatments helped to further the research on this type of cancer and get a little closer to a cure.
He was one of the strongest SOB's I have ever known based on all that I saw him go through. I am currently planning a fundraiser in his honor for the Mesothelioma Applied Research Foundation. It will be sometime in 2011. For more information on mesothelioma you can visit
