Asbestos was commonly used as insulation. Mineral can be found in pipe insulation in old houses. Do you have asbestos in your house? Find out what it is, if you have been exposed, how to perform it and the best methods to eliminate it. The name has its origin in the Greek word meaning inextinguishable.
Asbestos, a highly effective and economical fireproof material and thermal and acoustic insulation, was widely used in housing construction from the early 1940s to the 1970s. We now know that prolonged exposure to asbestos fibers can cause lung disease. When altered, tiny asbestos abrasive fibers are easily inhaled, damaging lung tissue and can cause. In houses built before 1975, asbestos is most commonly found as thermal insulation in boilers and basement pipes.
The mere presence of asbestos in your home is not dangerous. Usually, the material in good condition will not release asbestos fibers and altering it can create a health hazard where before there was no. The best thing to do with asbestos material in good condition is to leave it alone. The hazard comes from asbestos material that has been damaged over time.
Asbestos that crumbles easily if handled, or that has been cut, scraped, or sanded into dust, is likely to release asbestos fibers and create a health hazard. If you suspect that part of your home may contain asbestos, check periodically for tears, abrasions or water damage. If you discover slightly damaged material, limit access to the area and don't touch or disturb it. If the asbestos material is more than slightly damaged, or if you are going to make changes to your home that could disrupt it, a professional repair or removal is needed.
However, before calling an asbestos abatement contractor, you should contact an industrial hygiene company to inspect the affected area. An appropriate assessment shall include a thorough visual examination and careful collection and analysis of the samples. In addition, this inspector can perform checks after removal or repair to ensure that the area has been properly cleaned. With this report in hand, homeowners can contact an asbestos abatement contractor and negotiate a cleanup plan.
Repair involves sealing or covering the asbestos material. Sealing (encapsulation) treats the material with a sealant that binds the asbestos fibers or coats the material so that the fibers are not released. The insulation of pipes, furnaces and boilers can be repaired in this way. The cover (enclosure) involves placing a protective envelope or covering around the asbestos-containing material to prevent the release of fibers.
Only a professional trained to handle asbestos safely should perform these repairs. With any type of repair, asbestos remains in place. For more help dealing with asbestos problems in the home, contact your state's environmental affairs agency. If handled properly, you can prevent asbestos from causing a problem in your home.
Prepared by the American Lung Association Consumer Product Safety Commission (United States Environmental Protection Agency, 1990) The risk of lung cancer and mesothelioma increases with the amount of fibers inhaled. The risk of lung cancer from inhaling asbestos fibers is also higher if you smoke. Usually, people who get asbestosis have been exposed to high levels of asbestos for a long time. Symptoms of these diseases usually do not appear until about 20 to 30 years after the first exposure to asbestos.
Sometimes the best way to treat slightly damaged material is to limit access to the area and not touch or disturb it. Discard damaged or worn asbestos gloves, stove pads, or ironing board covers. Consult with local health, environmental, or other appropriate officials for proper handling and disposal procedures. REPAIR usually involves sealing or covering the asbestos material.
Sealing (encapsulation) involves treating the material with a sealant that binds the asbestos fibers or coats the material so that the fibers are not released. Insulation of pipes, furnaces and boilers can sometimes be repaired in this way. This should only be done by a professional who is trained to handle asbestos safely. The cover (enclosure) involves placing something on or around the asbestos-containing material to prevent the release of fibers.
Exposed insulated pipes may be covered with a protective wrap or jacket. Minor repairs should also be done by a professional, since there is always a risk of exposure to fibers when asbestos is altered. It is not recommended to carry out minor repairs yourself, since improper handling of asbestos materials can create a hazard where none exist. However, if you decide to do minor repairs, you should have as much information as possible about managing asbestos before doing anything.
Contact your state or local health department or EPA regional office for information on asbestos training programs. Your local school district may also have information on asbestos professionals and training programs for school buildings. Even if you have completed a training program, try nothing but minor repairs. Before performing minor repairs, carefully examine the area around the damage to make sure it is stable.
In general, any damaged area that is larger than the size of the hand is not a minor repair. REMOVAL is usually the most expensive method and, unless required by state or local regulations, it should be the last option considered in most situations. This is because removal represents the greatest risk of fiber release. However, it may be necessary to remove it when remodeling or making major changes to your home that may disrupt the asbestos material.
In addition, removal may be required if the asbestos material is severely damaged and cannot be repaired otherwise. Removal is complex and should only be performed by a contractor with special training. Improper Removal May Increase Health Risks for You and Your Family. Asbestos professionals receive training in material handling.
The type of professional will depend on the type of product and what needs to be done to correct the problem. You can hire a general asbestos contractor or, in some cases, a professional trained to handle specific products containing asbestos. Some companies offer combinations of testing, evaluation and correction. A professional hired to assess the need for corrective measures should not be connected with an asbestos correction company.
It is better to use two different signatures so that there is no conflict of interest. Services vary from area to area across the country. The workplace must be visually free of dust and debris. It may be necessary to monitor the air (to ensure that there is no increase of asbestos fibers in the air) to ensure that the contractor's work is done correctly.
This must be done by someone who is not connected to the contractor. Asbestos is the name given to a series of fibrous silicate minerals of natural origin extracted for their useful properties, such as thermal insulation, chemical and thermal stability and high tensile strength. Asbestos can be found not only in drywall sheets, but also in the composite of joints. Asbestos can be found in drywall since 1930 and in joint compounds from the 1940s to the 1980s.
Although it was banned in 1977, asbestos can still be found a few years later. Last week, I inspected a house built in 1980 that had an asbestos-containing gasket compound. Tiny asbestos fibers often end up in household products when asbestos is mixed with other materials, such as plastic or cement. While asbestos in household products is not easily identified only with the naked eye, it is sometimes possible to see asbestos fibers embedded in damaged materials containing asbestos.
Damaged, deteriorated or friable asbestos that dries and crumbles to dust can release asbestos fibers into the air that can be inhaled and can pose a health hazard to residents. Homeowners should be alert to the possibility of misleading claims by asbestos consultants and contractors. If you or a loved one has been diagnosed with mesothelioma after being exposed to asbestos at home, at work, or while serving in the military, you should seek legal advice immediately. Alteration of these materials could release microscopic asbestos fibers into the air, putting anyone who inhales these fibers at risk of developing a debilitating asbestos-related disease, such as mesothelioma.
It is not possible to determine whether brake or clutch components contain asbestos just by looking at them, but some vehicles and parts may contain labels indicating whether those components contain asbestos. The best way to avoid exposure to asbestos is to know the asbestos materials in your home, including their location and current status. If an inspection or study is required for asbestos, an Asbestos Notification Form (PDF) must be completed and sent to the U. To find out if your state has a training and certification program for asbestos removal contractors, and for information about EPA's asbestos programs, call EPA at (20) 554-1404.However, if disturbed, the asbestos material can release asbestos fibers, which can be inhaled into the lungs.
The District's Asbestos for Construction Fact Sheet (PDF) explains when an asbestos inspection may be required, who must perform it, and reporting requirements. People who were exposed to asbestos, either in their own home or through work in other people's homes, may develop mesothelioma and other asbestos diseases decades later. . .
