If you think there may be asbestos in your home, don't panic. Asbestos-containing materials that aren't damaged or disturbed are not likely to pose a health risk. Usually the best thing is to leave asbestos-containing material alone if it is in good condition.
No amount of asbestos is considered safe. Products that contain greater than 1 percent of asbestos minerals are considered to be asbestos-containing. The more asbestos you are exposed to, the more likely you are to get an asbestos disease. Asbestosis and lung cancer are dose-related diseases.
No, living in a house with asbestos in the walls is not safe. Asbestos is a known carcinogen, and breathing its fibers can cause major respiratory issues such as lung cancer and mesothelioma.
Asbestos fibers are not harmful unless they release into the air. When they are released, the fibers break down into tiny particles. The particles become airborne, and we inhale them. Then they collect in the lungs, causing scarring and inflammation.
Small amounts of asbestos are still used in some products and industries today. But the average person probably won't encounter it in high enough concentrations to increase their risk of developing a related cancer. Prolonged, repeated exposure to asbestos is required for cancer to become an issue.
Between 2-10% of people exposed to asbestos will develop a related disease. Between 80-90% of asbestos diseases are a type of lung disease.
Homes built before the 1980s likely have asbestos in them. For instance, if these homes have popcorn ceilings or vinyl flooring, they may contain asbestos. A simple rule is the newer a home is, the less likely it has asbestos materials. Homes built before the 1980s are likely to contain the mineral somewhere.
Asbestos and the risk of disease
However, the risk of developing an asbestos-related disease with exposure levels the public may experience on a daily basis is extremely low. For example, the background rate for getting mesothelioma is about 1 per million people per year.
See a GP if:
you have symptoms of asbestosis and think you've been exposed to asbestos.
Even if asbestos is in your home, this is usually NOT a serious problem. The mere presence of asbestos in a home or a building is not hazardous. The danger is that asbestos materials may become damaged over time. Damaged asbestos may release asbestos fibers and become a health hazard.
Asbestos is no longer added to popcorn ceilings because it's a known health risk. The chances of your ceiling containing asbestos are low for any installations in the late 1980s or after. Newly constructed ceilings don't use asbestos.
If you think there may be asbestos in your home, don't panic. Asbestos-containing materials that aren't damaged or disturbed are not likely to pose a health risk. Usually the best thing is to leave asbestos-containing material alone if it is in good condition.
Your older home probably did not come with an inventory of all asbestos containing materials, but if the house in which you live was built before 1980, there's a good chance that you'll find asbestos containing materials in the walls, ceiling, roof or floors – or all of the above.
One of the most worrying issues with asbestos is that in the event that it does get disturbed, it can be easily released into the air, and remain there for some time. It is thought that disturbed asbestos can stay airborne for as long as 48 to 72 hours before settling.
If you have a history of exposure to asbestos and you're experiencing increasing shortness of breath, you should contact your primary care doctor about the possibility of asbestosis. He or she likely will refer you to a doctor specializing in lung problems (pulmonologist).
When was asbestos used in homes? Because of its fire resistant and insulating properties, asbestos was commonly used between 1900 and 1980. Many homes built before the 1980s still contain asbestos ceiling tiles, insulation, piping, and flooring that must be professionally encapsulated or removed for health reasons.
It is difficult to tell when asbestos is in the air. The tiny fibers have no odor or taste, and they do not irritate your eyes or throat or make your skin itch. If you know or suspect there is asbestos in your home or workplace, leave the material alone.
As for how to test for asbestos yourself, only some states allow homeowners to perform a home asbestos test. Check with your state's environmental agency or health department first. If they allow it, you'll be able to purchase a kit with instructions on how to test for asbestos in the air.
One-time exposure to asbestos can cause diseases, including mesothelioma cancer. Researchers have found repeated exposure to asbestos increases the risk of developing asbestos-related cancers. The risk to individuals who have a one-time exposure to asbestos is generally lower compared to long-term or repeated exposure.
Approximately 12% of current homes in the U.S. were built prior to 1940. This data from the U.S. Census Bureau means more than half of U.S. homes were built with asbestos in or around the walls, floorboards, ceiling tiles, roof tiles, insulation, pipes and electrical wires.
The only way to be sure whether a material contains asbestos is to have it tested by a qualified laboratory. EPA only recommends testing suspect materials if they are damaged (fraying, crumbling) or if you are planning a renovation that would disturb the suspect material.
There's a good chance that if your home was built before the Carter administration, your family is at risk of asbestos and lead exposure. Both are extremely dangerous. Approximately 24 million housing units have deteriorated lead paint and elevated levels of lead-contaminated house dust.
