Sources: Asbestos was used in many products, ranging from insulating pipe and duct wrap to vinyl floor tiles and spackling. Thus, nearly all homes more than about 20 years old are likely to have some asbestos. If the material is in good condition and is left undisturbed, asbestos fibers should not become airborne and will not become a health hazard.
Health Effects: Asbestos can cause lung cancer, especially among smokers. About 600 to 1,000 U.S. deaths each year are attributed to asbestos; nearly all involve workplace exposure.
Detection: Consult a certified analytical lab for sampling instructions.
Solutions: The most important thing to know is that it should not be disturbed by those without professional certification. Amateur attempts to remove it are almost certain to create a serious hazard.
