Asbestos: A Toxic Danger in Older Homes

by Brian Turner

What should American homeowners do when they discover asbestos material in the home? The United States Consumer Product Safety Commission (CPSC) says, “If it is in good condition, leave it alone.” Their advice is based on the knowledge that asbestos is usually safe if it is undisturbed.
A problem occurs when asbestos materials are deteriorating or otherwise disturbed. This can be a big concern for Americans who are planning home renovations. The sanding and sawing that goes on during renovation projects are prime ways to disturb asbestos materials. This causes a release of toxic particles into the air, where they can become inhaled. Exposure to asbestos fibers has serious health consequences, including a risk for cancer.  
Asbestos in Home Construction
Asbestos is the commercial term for a group of six natural, fibrous minerals. For much of the last century, it was used in numerous consumer products such as building supplies. Although the government banned its use in 1977, the toxin continues to lurk in many homes today.
Old and brittle asbestos is often found in older homes, particularly during home renovation projects. Asbestos can live anywhere in the home: insulation, fireproofing materials, floor and ceiling tiles, roof and siding shingles and other building materials. When construction and carpentry work disturbs old asbestos, small fibers break off and escape into the air. Breathing these fibers pose health threats to contractors, carpenters, homeowners and their families.
Cancer and Other Health Risks
The risk of developing asbestos-related lung problems increases with the length of exposure and number of fibers inhaled. High levels of asbestos exposure over long periods of time can cause non-cancerous conditions such as pleurisy, asbestosis and other breathing problems.
Asbestos exposure has also been linked to lung cancer and an uncommon cancer called mesothelioma. This rare cancer usually attacks the lining of the lungs. In some cases, however, it may affect other organs in the chest cavity or abdominal cavity.
Protection and Prevention
American homeowners who plan to start home renovation projects should take care to protect themselves and their families from asbestos exposure. They can do this by avoiding renovation work in areas that have damaged asbestos materials. Sawing, sanding, scraping and drilling should also be avoided.
Rather than dusting, sweeping or vacuuming asbestos particles, they should hire an asbestos professional for cleanups. Wet mops reduce the risk of spreading airborne particles. Repairs, removal and disposal should only be handled by a professional who is trained in the proper handling of asbestos.
Homeowners can contact their local health officials or the EPA for help in finding a qualified asbestos inspector or contractor. Most states have training and certification programs for asbestos removal professionals.
