There are certified labs throughout the country that can identify asbestos in building materials see attached list. Contact a lab to find out how the sample should be collected and sent for testing. Do NOT try to take samples yourself unless specifically instructed how to do so - you don't want to risk exposure to the airborne fibers by disturbing it without taking the proper precautions.
Asbestos fibers can have serious effects on your health if inhaled. There is no known safe exposure to asbestos. The greater the exposure, the greater the risk of developing an asbestos-related disease. 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. Asbestos can cause asbestosis, a scarring of the lungs that leads to breathing problems and heart failure.
Workers who manufacture or use asbestos products and have high exposures to asbestos are often affected with asbestosis. Inhalation of asbestos can also cause lung cancer and mesothelioma , a rare cancer of the lining of the chest and abdomen lining.
It may be linked to cancer of the stomach, intestines, and rectum, as well. Synergistic effects can be substantial: in other words, exposure to asbestos is bad, but if you also smoke it is 1, times words, in terms of the risk of developing mesothelioma.
By EHSO. Toggle navigation Home. Beware pre asbestos use in homes and materials However, until the s, many types of building products and insulation materials used in homes contained asbestos. These fibres can be woven together. The main type of serpentine asbestos is chrysotile white asbestos , which is the main type of asbestos used in manufacturing. Amphiobole: Amphibole fibres are straight and stiff.
These fibres are generally brittle and rod- or needle-shaped, which limits their commercial usefulness. There are 5 sub-types of amphiobole asbestos, including:. Asbestos occurs in large natural deposits, or as contaminants in other minerals. For example, tremolite asbestos may occur in deposits of chrysotile, vermiculite, and talc.
Because it has heat-resistant and insulating properties, asbestos was used in a wide range of manufactured products. Before , asbestos was mainly used for insulating buildings and homes against cold weather and noise, and for fireproofing. Asbestos was used by industry, construction, and commercial sectors in products such as:.
All forms of asbestos are resistant to heat, fire, chemical, and biological break-down. Asbestos does not dissolve in water or evaporate. These properties mean that asbestos fibres do not burn, do not undergo significant reactions with most chemicals, and do not break down significantly in the environment. However, producer countries and some countries that still use chrysotile asbestos argue that this form of asbestos is safe if used correctly.
The World Health Organisation, various public health bodies and the public health community disagree. The Rotterdam Convention works by consensus among the signatory countries; one objection can derail a listing. Environmental Protection Agency finds exposure to asbestos in the chlor-alkali industry and elsewhere poses serious risk. One chemistry professor received four month prison sentence for producing the drug in a university lab, while another was acquitted.

What are the known health effects of asbestos? So asbestos is linked with deaths: how many? What does the asbestos industry say? Is asbestos likely to be banned soon? Table 2. Examples of Sources of Asbestos in the Environment.
Source of Asbestos Location in the Environment Mining, milling, and weathering of asbestos-bearing rock Outdoor air and settled dust Release of fibers from disturbed building materials e.
Key Points. Until the s, asbestos was widely used in the construction, shipbuilding, and automotive industries. Asbestos-contaminated vermiculite products were produced until Some home insulation and other building materials produced before contain asbestos.
Asbestos fibers are mainly released into the air when asbestos-containing materials are disturbed. More Related Links. Links with this icon indicate that you are leaving the CDC website.
