Asbestos is a mineral found in certain rock formations. When it is mined and processed, it can be converted into various materials made of tiny fluffy fibers. The individual fibers are 1,200 times smaller than a human hair-you can't see them without a microscope.

Asbestos and How it is Used

Asbestos is fire resistant. It is tough and resists corrosion. It is a good insulator. These qualities made it a valuable material to make products in many industries. In 1973 the federal government began prohibiting the use of materials made with asbestos, but some products produced before the ban are still in place in older buildings and cars. Here is a list of some products and materials that may contain asbestos:

Steam pipes, boilers and furnace ducts

Resilient floor tiles, vinyl sheet flooring and adhesives

Cement sheet, millboard and paper

Door gaskets

Soundproofing or decorative material

Patching and joint compound for walls and ceiling

Textured paints

Spray on fireproofing

Asbestos cement pipes and roofing

Shingles and siding

Automobile brake pads/linings, clutch facings+gaskets

Why is Asbestos a Hazard?

Materials that contain asbestos are not dangerous unless asbestos fibers are released from them. Today we know that breathing these fibers can damage your lungs and even cause lung cancer. The more fibers you inhale, the greater the risk of developing a serious problem. If you smoke, the problem is even more life threatening.

Since asbestos fibers are so small and light, they can remain in the air for many hours after they are released. This increases the chance that you might inhale them without knowing it.
