The EPA is the agency responsible for developing and enforcing regulations necessary to protect the general public from exposure to airborne contaminants. The MAP outlines training requirements and accreditation policies for persons who inspect for asbestos-containing material, design response actions, or carry out response actions.
Here are the common terms that everyone who deals with asbestos must know!
Asbestos-containing material (ACM) – This is any material containing more than 1% asbestos.
Presumed asbestos-containing materials (PACM) – These are materials that have not been tested but
potentially contain asbestos and, therefore, must be treated as ACM until testing can be done.
Friable asbestos material – This is any material containing more than 1% asbestos that, when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.
Non-friable ACM – These are materials in a building containing more than 1% asbestos that, when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure. A regulated area is an area established by an employer to indicate that it is closed off due to an asbestos release. Each area will be clearly indicated by warning signs.
Competent person – This is a person who has received special training according to the Environmental Protection Agency's (EPA) model accreditation plan (MAP) in order to
Health Risks Associated with Asbestos are Asbestosis, Lung Cancer and Mesothelioma.
Asbestosis is a disease characterized by fibrotic scarring of the lungs. This is a restrictive disease, which reduces the overall volume of the lung. Asbestosis is prevalent among workers who have been exposed to large doses of asbestos fibers over an extended period of time. The risk of asbestosis is minimal for those who do not work with asbestos; the disease is rarely caused by neighborhood or family exposure. Even after exposure to asbestos has ceased, scar tissue will continue to form around existing scar tissue and fibers trapped in the lung. Like all diseases associated with asbestos exposure, it usually takes many years for the disease to develop, typically 10 to 20 years.
Lung cancer causes the greatest number of deaths related to asbestos exposure. The incidence of lung cancer in workers who are directly involved in the use of asbestos and its products is significantly higher than in the general population. As with asbestosis, there exists a long lag time between initial exposure and the development of lung cancer, typically 20 years.
The asbestos-associated disease of greatest concern is probably mesothelioma. Fortunately, it is also the most rare. Mesothelioma is a form of cancer that most often occurs in the thin membrane lining of the lungs, chest, abdomen, and sometimes the heart. Only about 3,000 cases are diagnosed in the United States each year. Virtually all cases of mesothelioma are linked with asbestos exposure. Similar to the other diseases of asbestos, mesothelioma has a long latency period that may not develop for 20 to 40 years after initial exposure.
This Month we will discuss Asbestos. Well lets dig in. Asbestos is a dangerous mineral that causes mesothelioma which can lead to cancer. This mineral was used in construction to wrap pipes, insulation, some of the glue used in floor tiles and shingles, and even in duct tape. Between 1970 and 1975 the manufacturing of the product was halted. Thus most older structures has Asbestos.

When fibers are released into the are from the disturbance of Asbestos, then you are at risk of exposure. You may be exposed and not even know it. The symptoms from Asbestos exposure may not be revealed by your body until several years later during a health exam. Exposure to Asbestos can put you at risk of developing lung disease.
The three major disease that are associated with asbestos exposure are (1) Lung Cancer, (2) mesthelioma, a form of cancer (3) asbestosis, (non cancer long term lung disease).
If you are in an older structure asbestos could be in the following locations:
