Asbestos In The Home

Asbestos is a group of minerals that occur naturally as bundles of fibers. These fibers are found in soil and rocks in many parts of the world. They are made mainly of silicon and oxygen, but they also contain other elements. There are 2 main types of asbestos:. Asbestos fibers can be useful because they are strong, resistant to heat and to many chemicals, and do not conduct electricity. As a result, asbestos has been used as an insulating material since ancient times. Since the industrial revolution, asbestos has been used to insulate factories, schools, homes, and ships, and to make automobile brake and clutch parts, roofing shingles, ceiling and floor tiles, cement, textiles, and hundreds of other products.

During the first half of the 20th century, growing evidence showed that breathing in asbestos caused scarring of the lungs. Exposure to asbestos dust in the workplace was not controlled at that time.

Beginning in England in the s, steps were taken to protect workers in the asbestos industry by installing ventilation and exhaust systems. However, in the huge shipbuilding effort during World War II, large numbers of workers were exposed to high levels of asbestos.

As asbestos-related cancers became better recognized in the second half of the 20th century, measures were taken to reduce exposure, including establishing exposure standards and laws that banned the use of asbestos in construction materials. There has been a dramatic decrease in importing and using asbestos in the United States since the mids, and alternative insulating materials have been developed. As a result, asbestos exposure has dropped dramatically.

Asbestos use has been banned in the European Union sincealthough the ban did not require removal of asbestos that was already in place. Still, heavy asbestos use continues in some countries. Many people are exposed to very low levels of naturally occurring asbestos in outdoor air as a result of erosion of asbestos-containing rocks. The risk of this is higher in areas where rocks have higher asbestos content.

In some areas, asbestos can be detected in the water supply as well as in the air. It can get into the water through several sources, such as rock or soil erosion, corrosion of asbestos cement pipes, or the breakdown of roofing materials containing asbestos that then enter the sewers after it rains. However, the people with the heaviest exposure are those who worked in asbestos industries, such as shipbuilding and insulation.

Many of these people recall working in thick clouds of asbestos dust, day after day.Please read our information about coronavirus and cancer alongside this page.

Does Asbestos, One of Nature's Most Useful Minerals, Deserve its Bad Reputation??

If you have symptoms of cancer you should still contact your doctor and go to any appointments you have. Spotting cancer early means treatment is more likely to be successful. Read about coronavirus and cancer. My husband took apart an old storage heater apart today and thinks he breathed in a cloud of asbestos. What are is chances of developing problems later on? I think its mainly long term exposure that can cause problems later on.

I should think one incident should not be of concern, as its unlikely to have caused damage.

I think its best to give to room where this heater was plenty of air and have it checked out by professionals to make sure no other asbestos is present. The risk of developing an asbestos-related illness following an exposure of short duration, even to high levels, is very low. Smoking increases risk.

I wonder if there is any way of finding out what really was in the storage heater. The Asbestos Information Centre may be able to help with this. The Gov UK website says that your local council can provide information about asbestos so it may be worth contacting them and getting some advice for example about how to dispose of the storage unit and finding out if anything else needs to be done.

The Health and Safety Executive which is really about health and safety at work has some information for members of the public about asbestos here. The problem with Asbestos is that it lodges into the inside of your lungs and irritates your lungs by cutting the inside of your lungs because it's a very sharp substance.

What happens then is your lungs try to repair them selfs and should be able to but eventually in the process a cell may mutate when repairing and turn cancerous. The lung builds a scar tissue over the asbestos particles and they keep cutting you up basically and we all know that constant truama can and often does lead to cancer. All this being said your lungs are very good at clearing them selfs out and getting rid of unwanted stuff. Hope your husband doesn't worry about this because he should be fine!

I worried for months when I took down my garrage room and I'm only 18 haha. Update: This is the way one can develop lung cancer from Asbestos however I think Asbestosis is similar in the way that the Asbestos shreds the lungs. Wearing a mask may be highly annoying but just think about your lungs! Why does everybody talk about how the exposure develops into cancer and how little the likelyhood was that it was asbestos but noone answers what to do if you were exposed to it except by visiting GP?

What can GP tell you? Is there actually something you can take to help it clear out after recent exposure?This page was medically reviewed by on. For information on our content creation and review process read our editorial guidelines.

Asbestos Exposure and Cancer Risk

If you notice an error or have comments or questions on our content please contact us. Asbestos is a natural mineral that has been mined and used for centuries because of its durability, heat and chemical resistance.

At the height of its use, asbestos could be found in over 3, consumer products. Over time, however, researchers realized that when asbestos materials are disturbed or damaged, asbestos fibers can be released into the air and cause dangerous exposure. Request a Free Mesothelioma Guide. From the s through the late s, asbestos use skyrocketed throughout the United States and the world, putting millions of people at risk of exposure.

Throughout this same time period, the connection between asbestos exposure and cancer risk became more clear, as more reports of mesothelioma and other asbestos diseases flooded in.

Any amount of asbestos exposure, even limited, is considered dangerous and can later lead to a mesothelioma diagnosis. When inhaled or ingested, the microscopic asbestos fibers work their way into the lining of the lungs, abdomen or heart. Over a period of 10 to upwards of 50 years, the fibers can cause inflammation and scarring, which can eventually develop into mesothelioma tumors or other related conditions.

While some of these asbestos diseases, like pleural thickening and pleural plaques, are not considered deadly and can be managed like a chronic disease, mesothelioma has an average prognosis of just 12 to 21 months.

Preventing asbestos exposure is vital while the mineral is not yet banned and past uses still linger throughout the world. While the uses of asbestos in America today are much more limited, the toxin can still be found in thousands of older homesbuildings and schools built before Knowing where asbestos can potentially be found is important in preventing exposure. While there is no way to easily identify asbestos with the naked eye, there are some products and areas of the home that are more likely to have been made with the mineral.

These are just a sample of numerous products that have been made with asbestos over the years. In addition to being knowledgeable about common asbestos productsit can also be helpful to be aware of the six types of asbestos and how they have been used in the past. While all forms of asbestos are considered carcinogenic, researchers have noted that some types are more dangerous than others and more likely to lead to mesothelioma or another similar diagnosis.

Chrysotile asbestos is the most common form of the silicate mineral. This mineral is classified as serpentine for its long, curly fibers that can be woven. It was used in many commercial applications, including flooring, walls, ceilings, and roof materials. Amosite was predominantly used in construction including cement sheets, pipe insulation, and ceiling tiles.

Fortunately, amosite is no longer actively being mined for commercial use.

It has also been found as a contaminant in talc powders and chrysotile. Crocidolite is harder and more brittle than other forms of asbestos because it forms in bundles of long, straight fibers. This type of asbestos can break very easily, making it the most lethal form of asbestos. Anthophyllite can be noted by its grey-brown color.

It has long, flexible fibers, primarily composed of magnesium and iron. It is not mined commercially and is one of the least common types of asbestos. It can be found as a contaminant in some flooring products.This information will help you understand asbestos. What it is, its health effects, where it is in your home, and what to do about it. 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. Disturbing it may create a health hazard where none existed before.

Read this before you have any asbestos material inspected, removed, or repaired. Asbestos is a mineral fiber. It can be positively identified only with a special type of microscope. There are several types of asbestos fibers. In the past, asbestos was added to a variety of products to strengthen them and to provide heat insulation and fire resistance.

From studies of people who were exposed to asbestos in factories and shipyards, we know that breathing high levels of asbestos fibers can lead to an increased risk of:. The risk of lung cancer and mesothelioma increases with the number of fibers inhaled.

The risk of lung cancer from inhaling asbestos fibers is also greater if you smoke. People who get asbestosis have usually been exposed to high levels of asbestos for a long time. The symptoms of these diseases do not usually appear until about 20 to 30 years after the first exposure to asbestos. Most people exposed to small amounts of asbestos, as we all are in our daily lives, do not develop these health problems.

However, if disturbed, asbestos material may release asbestos fibers, which can be inhaled into the lungs. The fibers can remain there for a long time, increasing the risk of disease. Asbestos material that would crumble easily if handled, or that has been sawed, scraped, or sanded into a powder, is more likely to create a health hazard. Most products made today do not contain asbestos. Those few products made which still contain asbestos that could be inhaled are required to be labeled as such.

However, until the s, many types of building products and insulation materials used in homes contained asbestos. Common products that might have contained asbestos in the past, and conditions which may release fibers, include:. You can't tell whether a material contains asbestos simply by looking at it, unless it is labeled. If in doubt, treat the material as if it contains asbestos or have it sampled and analyzed by a qualified professional.

A professional should take samples for analysis, since a professional knows what to look for, and because there may be an increased health risk if fibers are released. In fact, if done incorrectly, sampling can be more hazardous than leaving the material alone. Taking samples yourself is not recommended. If you nevertheless choose to take the samples yourself, take care not to release asbestos fibers into the air or onto yourself. Material that is in good condition and will not be disturbed by remodeling, for example should be left alone.

Only material that is damaged or will be disturbed should be sampled.Health Sciences.

The School District of Philadelphia has an ongoing asbestos crisis that, as of Feb. Asbestos, a material mined in the ground, is one of six fibrous silicate metals. Useful because it is chemically non-corrodible and fire- and heat-resistant, it has been used in roof shingles, ceiling and floor tiles, brake linings and pads, and as insulation on pipes.

Although no longer excavated in the United States, it can be imported and is still utilized in the manufacture of brake pads. Ambler, Pennsylvania, about 14 miles outside of Philadelphia, was formerly home to the biggest asbestos manufacturing facility in the world. As asbestos deteriorates, it can release hazardous small fibers into the air. When inhaled, these fibers can cause lung cancer, asbestosis, or scarring of the lung tissue, mesothelioma, a deadly cancer of the lining of the lungs, and other asbestos-related diseases, which can take decades to manifest.

Homes, schools, and buildings built before —the majority of structures in Philadelphia—have a higher risk of containing asbestos, usually covering pipes or in roofing tiles. Each year, approximately 50, people in the United States die from asbestos-related diseases, and more thanpeople perish worldwide. Penn Today spoke with Ian A. Blaira scientist at the Perelman School of Medicine who has worked on community-based concerns about hazardous asbestos waste in Amblerand Marilyn Howarthan occupational and environmental medicine physician at Penn Medicine and a technical adviser on the Philadelphia Healthy Schools Initiativeabout the dangers of asbestos, how it harms the body, the crisis in the school district, and why there is no safe level of asbestos.

What is it about asbestos that makes it so dangerous? According to some people, chrysotile is less dangerous than the other forms of asbestos, but if you actually really look at the data, it seems just as dangerous to me.

Crocidolite is thought to be the most dangerous. Then ultimately that cell dies and those enzymes spill out, and they injure the cells around them. The enzymes are useful inside cells but harmful outside cells in contact with other cells. This process causes inflammation.

So, the asbestos fibers just remain in your body? They remain there and continue to cause trouble. How are people usually exposed to asbestos? Most of the exposures now come from natural asbestos or potential exposures from sources such as the piles of asbestos material that was left in Ambler. Most of the Philadelphia schools have asbestos-insulated pipes. What happens is as the insulation ages, it becomes very friable and tends to break up, and you see deposits of asbestos fibers on floors and surfaces of rooms.Browse All Regulations.

I'm looking for support for Asbestos dangers are still here, even though the building material was banned, or mostly banned, over three decades ago. Hear this podcast for the hazards and solutions. Asbestos was used in many construction materials up to It was banned for common usage due to health issues such as asbestosis, mesothelioma and lung cancer.

Asbestos is a naturally occurring mineral found in many parts of the world, mined primarily in Canada, South Africa and the United States. It has been used since the time of the ancient Greeks and Romans and was prized for its heat resistant properties. Used to insulate the boilers of steam locomotives in the 's, asbestos was not in widespread use until the 's.

According to the Environmental Protection Administration EPAin that time overschools andpublic and commercial buildings used asbestos for insulation, decoration and fireproofing. We know now what they did not know then Asbestos is literally everywhere! So why this 30 year love affair?

Asbestos has qualities that set it apart from any other material. It is virtually indestructible; it does not decompose or decay; it is a poor conductor of electricity; it is resistant to heat, chemicals, and water. Like the proverbial "bad penny", you just can't get rid of it!! It exists in microscopic fibers of varying sizes. When mixed with other materials, it passes on its insulating properties while adding its fibrous strength.

Automotive and elevator brake linings and clutch pads, high temperature gaskets, heat-proof gloves, fire blankets and protective clothing, stovetop heat resistant pads; paper products; and plastics. You can now understand why asbestos became so widely used that it has touched all our lives. Even the brightest clouds have a dark lining and, with asbestos, the dark lining was within the human lung. The unique dangers of asbestos were ignored by the industry but were painfully obvious to those who worked in the mines or produced asbestos products.

Asbestos workers were exposed to large amounts of airborne asbestos and brought the dust into their homes for their families to inhale or ingest in their food. Though the connection is less strong, many physicians believe that cancers of the digestive system and other organs may be related to the ingestion of asbestos through contaminated food and water supplies.

Because the onset of these diseases can take up to 30 years, their connection to asbestos inhalation was painfully slow in coming. Studies also show a deadly connection between asbestos exposure and cigarette smoking. The chance of lung disease nearly doubles in a smoker who is also exposed to asbestos. In my research for this article, I stumbled across a medical questionnaire from OSHA for employees in the asbestos industry. Almost a third of the form deals with cigarette, cigar, and pipe smoking habits and history emphasizing the serious nature of this interaction.

The value of the information obtained is enormous The day of reckoning did finally arrive in the 's with the first lawsuits. The judicial frenzy reached its peak in when the EPA proposed an immediate ban on the use of asbestos in certain products and a total ban within 10 years.

Over time cooler heads prevailed Rather, the court ruled to overturn most of the EPA's ban, and instead limited the ban to include 1 the development of new uses for asbestos and 2 the reintroduction of asbestos into industries where it had been replaced by other products. A body of evidence has emerged showing that exposure must reach fairly high levels over extended periods of time before evidence of disease is manifested. One of their more frightening lines of argument is that many of the products used to replace asbestos may in fact be as bad or worse from a public health perspective.
