Asbestiform minerals, wherever they are, become a potential health problem once they are disturbed. Asbestiform minerals, wherever they are, become a health problem once they are disturbed. Breathing in the fibers is the primary way that people are exposed to asbestos, according to the Centers for Disease Control and Prevention CDC.
Most people who die from mesothelioma are elderly men who were exposed to asbestos from working with or near asbestiform material decades earlier. According to a report by the Environmental Working Group EWG Action Fund, 2,—3, Americans are diagnosed with mesothelioma each year, and 12,—15, Americans die from asbestos-related diseases each year.
For the — period, Nevada had a global age-standardized incidence rate of 10 cases of malignant mesothelioma per million inhabitants each year. This rate is similar to the mean U. An analysis of all malignant mesothelioma deaths recorded in Nevada for the — period shows a constant mortality rate. However, Nevada is not listed among the states having produced asbestos or showing a high occupational exposure.
For this reason, the standardized incidence of 10 per million is unexpectedly high, compared with the background incidence of 5 per million in other states without known occupational exposure. In addition, Pfau said, many of the cases are in women and younger people. Chrysotile exposure can lead to mesothelioma by suppressing the immune system, allowing cancer to grow.
Amphibole asbestos, on the other hand, causes an elevated immune response, leading to systemic autoimmune diseases like lupus, rheumatoid arthritis, and scleroderma, as well as mesothelioma. The first step is knowing where the risk is.

Types of Asbestos The Asbestos Hazard Emergency Response Act of legally recognizes six types of asbestos that fall into two categories: Amphibole and serpentine. Crocidolite Amosite Anthophyllite Tremolite Actinolite. This sample from Canada shows the curly structure of chrysotile asbestos. Where Does Asbestos Come From? Asbestos-Related Diseases Scientific studies show exposure to asbestos is linked to several diseases, including cancers.

Asbestos Products When Americans are exposed to asbestos today, it is usually through renovation or demolition work on an old building that still contains legacy asbestos products. Discontinued asbestos products Vinyl asbestos tiles Asbestos cement Asbestos roofing felt Asbestos adhesives, sealants and coatings Asbestos reinforced plastics. Learn More About Asbestos Products. Pittsburgh Corning Armstrong World Industries.
Learn More About Asbestos Companies. How to Identify Asbestos Products Microscopic asbestos fibers cannot be seen, smelled or tasted. Asbestos materials fall into two risk categories:. Friable asbestos materials Friable asbestos materials are easy to break or crumble by hand. Examples include old asbestos pipe insulation and talcum powder contaminated with asbestos. These materials are dangerous because they can easily release toxic dust into the air.
Nonfriable asbestos materials Nonfriable asbestos materials, such as asbestos cement slabs and vinyl asbestos tiles, are durable. These products keep asbestos fibers safely trapped as long as the products are undisturbed. Sawing, scraping or smashing the product may release fibers. Tips for Safely Handling Asbestos Some situations require the removal of asbestos-containing materials.
If you are considering DIY asbestos abatement, remember the following precautions: Seal off the work area with plastic sheets and turn off the air conditioning. Wear a respirator with a high efficiency particulate air HEPA filter. Wear disposable coveralls and gloves during asbestos abatement. Use a pump sprayer to keep asbestos materials wet and suppress dust at all times.
Clean the work area with wet wipes or a vacuum cleaner with a HEPA filter. Dispose of asbestos waste in clearly labeled bags at a landfill that can accept asbestos. Is Asbestos Banned? Safe Alternative to Asbestos Since the s, manufacturers in the United States have largely phased out the use of asbestos, relying instead on several safer substitutes. Polyurethane foam Polyurethane foam is cheap and effective for insulation. Construction workers can easily apply spray polyurethane foam to insulate and seal.
Amorphous silica fabric Amorphous silica fabric is a high-quality cloth woven from nearly pure amorphous silica fibers. If asbestos fibers are in the air you breathe, you might get asbestos fibers in your lungs. Breathing in the fibers is the primary way that people are exposed to asbestos. More information about asbestos and health and limiting exposures to naturally occurring asbestos is found at basic information about naturally occurring asbestos.
Fairfax County, Virginia has developed procedures for maintaining safe working conditions on construction sites in areas of naturally occurring asbestos and to prevent migration of asbestos laden dust off these sites naturally occurring asbestos in Fairfax County External.
Naturally Occurring Asbestos. Section Navigation. Facebook Twitter LinkedIn Syndicate. Where is Asbestos Found?
A map showing these areas can be seen here. It is unlikely to be practical to remove the NOA, and strict controls would need to be put in place throughout the whole operation of removal. However, covering the NOA with clean soil or other material that does not contain NOA is recommended as a satisfactory and effective solution.
Where covering is not practicable, a NOA area should be managed in a way that minimises the generation of dust. It is not likely to be practical to remove NOA. The presence of NOA is one of many natural attributes that determines that productivity and value of any land. Local councils who confirm the presence of naturally occurring asbestos on land that is not identified on the mapping can provide the information to the Geological Survey of NSW.
The information must be in the form of a report prepared by a qualified person that identifies the type of asbestos and its confirmed location. Publication , August Print PDF. Asbestos occurs in some rocks and soils as a natural mineral.
Asbestos is not considered dangerous when it is left undisturbed. When asbestos is disturbed or worked with, asbestos fibres can be released into the air. Breathing in asbestos fibres can increase the risk to your health but does not necessarily mean you will develop health problems. The risk of developing an asbestos-related disease depends on how many fibres have been breathed in and for how long, type of fibre, whether you smoke and age at first exposure. It is prudent to take simple precautions where practical to minimise potential exposure.
The maps identify potential locations of naturally occurring asbestos - they do not identify all places where it actually exists. What is NOA and how does it form? These NOA factsheets contain further information: Recreation in areas of naturally occurring asbestos Residing in areas of naturally occurring asbestos Farming in areas of naturally occurring asbestos Where is NOA typically found, and how can I recognise landscapes where NOA might occur? What does NOA look like? Figure 1. Naturally occurring asbestos outcrops and rocks confirmed Who can I contact to determine if I have NOA on my property?
Health What is the risk of developing an asbestos-related disease? What are asbestos-related conditions?
The four main asbestos-related conditions are pleural plaques, asbestosis, lung cancer and mesothelioma: Pleural plaques are areas of white, smooth, raised scar tissue on the outer lining of the lung, internal chest wall and diaphragm.
