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.
How Bad Is One-Time Exposure to Asbestos? Usually, one-time asbestos exposure isn't a major risk. However, it can be in rare cases with toxic dust. Typically, asbestos diseases arise from long-term exposure at work.
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.
See a GP if:
you have symptoms of asbestosis and think you've been exposed to asbestos.
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.
This means 5500 fibres are inhaled/day by the average person (proportion of time spent indoors = 20 hours/day). Despite this the general population does not contract asbestos-related disease in significant numbers. The background rate of mesothelioma is less than one per million per year.
If you suspect material contains asbestos, don't touch it. Look for signs of wear or damage such as tears, abrasions, or water damage. Damaged material may release asbestos fibers. This is particularly true if you often disturb it by hitting, rubbing or handling, or if it is exposed to extreme vibration or air flow.
It may take five to 20 years before symptoms develop. The accumulated, inhaled asbestos fibres produce scarring (fibrosis) of the lung. The lung develops a 'honeycomb' appearance. The scar tissue, or 'fibrosis', is hard and inflexible – this makes the lungs stiffen and stops them working properly.
No known method exists to remove asbestos fibers from the lungs once they are inhaled. Some types of asbestos are cleared naturally by the lungs or break down in the lungs.
Anyone who has been suffering from asbestosis within the last three years can make a claim for asbestosis compensation. This is because there is a time limit of three years in which you are able to start a claim.
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.
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.
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.
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.
A material is considered to contain trace levels of asbestos if the concentration of asbestos in the material is identified to be less than 1%. NYS Department of Labor's Asbestos regulations (Code Rule 56) and the US EPA's Asbestos NESHAPs regulations do not apply to materials containing <1% asbestos.
How much asbestos is dangerous? 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.
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.
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.
The symptoms of asbestos-related diseases may not become apparent for many decades after the exposure. It is particularly important to check with a doctor if any of the following symptoms develop: Shortness of breath, wheezing, or hoarseness. A persistent cough that gets worse over time.
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.
If you are not licensed to work with asbestos, and you are worried that you have accidentally disturbed an asbestos containing material – you should stop work immediately and evacuate both yourself and anyone else working in the area. You should evacuate the area as quickly as possible, providing it is safe to do so.
Asbestosis symptoms can range from mild to severe, and usually don't appear until many years after initial exposure.
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.
