QuestionI'm always hearing about asbestos and its hazards, but I don't really know what asbestos is. What is asbestos? Where does it come from?

AnswerAsbestos is a fibrous mineral that is mined in the same way as copper, iron, and lead. It's a compound of silicon, oxygen, hydrogen, and various metal cations (positively charged metal ions).

There are many varieties of asbestos; the three most common are chrysotile, amosite, and crocidolite. Chrysotile was first commercially mined in the 1870s in Quebec, Canada. Amosite was first mined in South Africa in 1916, and crocidolite asbestos also came from Africa beginning in the 1980s.

Unlike most minerals which turn into dust particles when crushed, asbestos breaks up into fine fibers too small to be seen by the naked eye. Since an average human hair is approximately 1200 times thicker than an asbestos fiber, it takes an extremely powerful microscope to see the fibers.

Asbestos fibers are commonly mixed with other materials which bind them together so they can be used in many different building products. If these light hard-to-see fibers are released from an asbestos containing material (ACM), they will remain in the air for hours.

I've been in the construction field for over 25 years and wish I'd known then what I know now about asbestos. I would not have tackled a lot of projects because of the asbestos content of certain building products.

To get the whole picture, I recommend that you purchase my informative article, Asbestos In Popcorn Ceilings, which describes how to determine if asbestos is present and the steps a professional takes to decide if removal is the correct course of action. These same steps apply to homeowners facing the same decisions.
