In 1876, chrysotile was discovered in the Thetford Township, in southeastern Quebec. Shortly afterward, Canadians established the world’s first commercial asbestos mines. They joined Russia in excavating the soft, fibrous form of the mineral, which is found in more than 95 percent of all asbestos products.
Despite the fact that asbestos was outlawed in 1977, it can still be discovered in some places a few decades later. A residence built in 1980 with asbestos-containing joint compound was under inspection last week, and I found it to be in good condition. The amount of time between exposure to asbestos and the first signs of disease can be as much as 30 years. It is known that smokers exposed to asbestos have a much greater chance of developing lung cancer than just from smoking alone. However, until the 1970s, many types of building products and insulation materials used in homes contained asbestos. For more information on the 1970's and 1980's bans, click here.
Where Can Asbestos Hazards Be Found In The Home?

But if a house was built before the 1980s and has not been renovated, its construction has likely used asbestos in more than one way. Homeowners should also verify that the contractor has a general liability and workman's compensation policies that cover this type of work. In many states, contractors are required by law to notify federal, state and local agencies that they are about to perform abatement activities.
When Did They Start Using Insulation in Homes?
But by the late 1970s, a dramatic decline began in the use of asbestos throughout the industrialized nations. The public was beginning to understand the connection between asbestos exposure and debilitating lung diseases. In the United States, increased consumption stemmed from the population’s growing demand for cost-effective, mass-produced construction materials. The U.S. quickly became the world leader in asbestos usage, with neighboring Canada furnishing a steady supply.
Always wet the asbestos material using a fine mist of water containing a few drops of detergent. Commercial products designed to fill holes and seal damaged areas are available. Small areas of material such as pipe insulation can be covered by wrapping a special fabric, such as rewettable glass cloth, around it. These products are available from stores (listed in the telephone directory under Safety Equipment and Clothing") which specialize in asbestos materials and safety items.
When was asbestos first dangerous?
The website is updated with new questions every day, so it is always up-to-date. After you enter your information you will receive your book and additional materials in accordance with our privacy policy. Congress passes the Clean Air Act, allowing the Environmental Protection Agency to regulate asbestos as a hazardous air pollutant.
Throughout this time, asbestos was commonly used in wall insulation, floor tiles, ceiling material, siding, and pipe insulation. If you breathe asbestos fibers, you may increase the risk of several serious diseases, including asbestosis, mesothelioma and lung cancer. Asbestos exposure may increase your risk for cancers of the digestive system, including colon cancer.
Do lungs clean themselves of dust?
The fibers accumulate in the lungs over time and eventually lead to mesothelioma. Before work begins, get a written contract specifying the work plan, cleanup, and the applicable federal, state, and local regulations which the contractor must follow . Contact your state and local health departments, EPA's regional office, and the Occupational Safety and Health Administration's regional office to find out what the regulations are. Be sure the contractor follows local asbestos removal and disposal laws. At the end of the job, get written assurance from the contractor that all procedures have been followed.
The water/detergent mist will reduce the release of asbestos fibers. These products are not likely to release asbestos fibers unless sawed, dilled, or cut. Talk to your doctor if you think you’ve been exposed to asbestos. They can help you determine your risk of developing an asbestos-related disease. “The good news is that one-off, limited exposure to asbestos is typically harmless short and long term,” says Dr.
The greater the exposure, the greater the risk of developing an asbestos-related disease. Additionally, asbestos was voluntarily withdrawn by manufacturers of electric hair dryers. Many homes built before 1980 have asbestos in their flooring, paint, plaster, or insulation, so during demolition, it’s essential to wear proper safety gear and masks with filters. Sadly, many construction materials continue to contain asbestos. Asbestos was discovered by the Ancient Greeks more than two thousand years ago.
If you decide on removal, be sure to get written assurance from the contractor that he or she has followed all local asbestos removal and disposal laws. But they especially like to make their homes on any damp surfaces, or humid locations they can find. As a result, they can pose many health risks, such as asthma, eczema, upper and lower respiratory symptoms, and respiratory infections, to name a few.

Commercial production of asbestos insulation began in 1879, and the first case of asbestos-related disease, described as “curious bodies” in the lungs was detected in 1899. The first cases of asbestosis and lung cancer attributable to asbestos exposure were diagnosed in the United States in 1935. Since the late 1800s, friable asbestos materials have been widely employed in commercial and industrial settings for fireproofing, soundproofing, and insulation purposes, among other things. Some friable products were also used in the construction of houses, and some of these products can still be found in houses built before 1990. Assure that the contractor avoids spreading or tracking asbestos dust into other areas of your home. They should seal the work area from the rest of the house using plastic sheeting and duct tape, and also turn off the heating and air conditioning system.
