What are the health hazards of exposure to asbestos?
People may be exposed to asbestos in their workplace, their communities, or their homes. If products containing asbestos are disturbed, tiny asbestos fibers are released into the air. When asbestos fibers are breathed in, they may get trapped in the lungs and remain there for a long time. Over time, these fibers can accumulate and cause scarring and inflammation, which can affect breathing and lead to serious health problems (6).
Asbestos has been classified as a known human carcinogen (a substance that causes cancer) by the U.S. Department of Health and Human Services, the EPA, and the International Agency for Research on Cancer (2, 3, 7, 8). Studies have shown that exposure to asbestos may increase the risk of lung cancer and mesothelioma (a relatively rare cancer of the thin membranes that line the chest and abdomen). Although rare, mesothelioma is the most common form of cancer associated with asbestos exposure. In addition to lung cancer and mesothelioma, some studies have suggested an association between asbestos exposure and gastrointestinal and colorectal cancers, as well as an elevated risk for cancers of the throat, kidney, esophagus, and gallbladder (3, 4). However, the evidence is inconclusive.
Asbestos exposure may also increase the risk of asbestosis (a chronic lung disease that can cause shortness of breath, coughing, and permanent lung damage) and other nonmalignant lung and pleural disorders, including pleural plaques (changes in the membrane surrounding the lung), pleural thickening, and pleural effusions (abnormal collections of fluid between the thin layers of tissue lining the lung and the wall of the chest cavity). Although pleural plaques are not precursors to lung cancer, evidence suggests that people with pleural disease caused by asbestos exposure may be at increased risk for lung cancer (9).

U.S. Environmental Protection Agency Asbestos Information
Information on asbestos uses, health hazards, sources, cancer risks, physical proprties and more can be found at the U.S. Environmental Protection Agency (EPA) website at http://www.epa.gov/ttnatw01/hlthef/asbestos.html
Some of the information on the site includes:
Hazard Summary-Created in April 1992; Revised in January 2000
Asbestos has been used in building materials, paper products, plastics, and other products. Exposure mainly occurs in indoor air where it may be released from these materials. Effects on the lung are a major health concern from asbestos, as chronic (long-term) exposure to asbestos in humans via inhalation can result in a lung disease termed asbestosis. Asbestosis is characterized by shortness of breath and cough and may lead to severe impairment of respiratory function. Cancer is also a major concern from asbestos exposure, as inhalation exposure can cause lung cancer and mesothelioma (a rare cancer of the thin membranes lining the abdominal cavity and surrounding internal organs), and possibly gastrointestinal cancers in humans. EPA has classified asbestos as a Group A, known human carcinogen.

Asbestos Facts and Information
As per the Agency for Toxic Substances and Disease Registry -Asbestos Facts are as follows:
- When asbestos fibers are inhaled, most fibers are expelled, but some can become lodged in the lungs and remain there throughout life. Fibers can accumulate and cause scarring and inflammation. Enough scarring and inflammation can affect breathing, leading to disease.
- People are more likely to experience asbestos-related disorders when they are exposed to high concentrations of asbestos, are exposed for longer periods of time, and/or are exposed more often.
- Inhaling longer, more durable asbestos fibers (such as tremolite and other amphiboles) contributes to the severity of asbestos-related disorders.
- Exposure to asbestos, including tremolite, can increase the likelihood of lung cancer, mesothelioma, and non-malignant lung conditions such as asbestosis (restricted use of the lungs due to retained asbestos fibers) and changes in the lung lining.
- Changes in the lining of the lungs (pleura) such as thickening, plaques, calcification, and fluid around the lungs (pleural effusion) may be early signs of asbestos exposure. These changes can affect breathing more than previously thought. Pleural effusion can be an early warning sign for mesothelioma (cancer of the lining of the lungs).
- Most cases of asbestosis or lung cancer in workers occurred 15 years or more after the person was first exposed to asbestos.
- Most cases of mesothelioma are diagnosed 30 years or more after the first exposure to asbestos.
- Mesothelioma has been diagnosed in asbestos workers, family members, and residents who live close to asbestos mines.
- Health effects from asbestos exposure may continue to progress even after exposure is stopped.
- Smoking or cigarette smoke, together with exposure to asbestos, greatly increases the likelihood of lung cancer. See Cigarette Smoking, Asbestos Exposure, and your Health.

EPA fines six Arizona charter school operators for asbestos violations Schools failed to have inspections completed and asbestos management plans
The U.S. Environmental Protection Agency recently fined six Arizona charter school operators a combined total of $11,600 for Asbestos Hazard Emergency Response Act violations.
In April 2007, EPA inspectors discovered that all but one of the school operators failed to conduct inspections to determine if asbestos-containing material was present in school buildings and all had failed to develop asbestos management plans. The schools have since completed inspections or otherwise obtained the appropriate documentation to establish that no asbestos-containing material is present in their school buildings. All of the schools have developed asbestos management plans.
“All schools, including charter schools, need to conduct asbestos inspections and have asbestos management plans,” said Katherine Taylor, associate director for the Communities and Ecosystems Division in EPA’s Pacific Southwest region. “Asbestos in schools has the potential for endangering the health of students, teachers, and others, including maintenance workers.”
The schools are:
* Valley Academy: The operator Valley Academy, Inc. was fined $2,400.
* Paradise Education Center: The operator, Paragon Management, Inc. was fined $2,100.
* Horizon Community Learning Center: The operator Horizon Community Learning Center, Inc. was fined $2,100.
* Happy Valley School: The operator Happy Valley School, Inc. was fined $2,100.
* Edu-Prize Charter School: The operator Edu-Prize, Inc. was fined $2,100.
* Challenge School: The operator Challenge School, Inc. was fined $800.
Federal law requires schools to conduct an initial inspection using accredited inspectors to determine if asbestos-containing building material is present and develop a management plan to address the asbestos materials found in the school buildings. In certain circumstances, an inspection is not required if the school has a signed statement from the architect or builder stating that a new building was constructed with no asbestos-containing materials.
All six schools established that no asbestos-containing materials were used in their school buildings. Schools that do not contain asbestos-containing material must still develop a management plan that identifies a designated person and includes the architect’s statement or building inspection and the annual notification to parents, teachers, and employees regarding the availability of the plan.
The EPA’s rules also require the school to appoint a designated person who is trained to oversee asbestos activities and ensure compliance with federal regulations. Finally, schools must conduct periodic surveillance and re-inspections, properly train the maintenance and custodial staff, and maintain records in the management plan.
Local education agencies must keep an updated copy of the management plan in their administrative office and at the school, which must be made available for inspection by parents, teachers, and the general public.

Dealing with Debris and Damaged Buildings
As per the EPA - EPA's guidance has been requested on the demolition of structurally unsound buildings damaged by Hurricane Katrina. Various federal regulations apply to building demolition activities. Areas of primary federal concern include asbestos demolition requirements, the proper disposal of electrical equipment containing PCBs (i.e., distribution transformers and capacitors) and storage tanks. EPA recognizes the difficult circumstances faced in demolishing structurally unsound buildings damaged by Hurricane Katrina may make full compliance difficult. However, in any event, you should take the actions set forth below to the extent feasible.
Efforts to restore the damaged areas to their pre-disaster condition often involve removing or repairing damaged structures. There may be a natural tendency at this stage to overlook certain hazards, such as asbestos, that are not immediately life threatening. However, such hazards are serious and may manifest themselves many years from the time of exposure and should be taken into consideration. Given the health hazards associated with asbestos, PCBs, lead, and other harmful substances, it is reasonable that adequate measures be taken during emergency situations to minimize exposure to such materials from the demolition of buildings.
The following guidelines are provided to help minimize the health, safety and environmental risks associated with the demolition of structurally unsound buildings (structures that remain standing but are in danger of imminent collapse). In the case of such buildings it would be unsafe to enter or inspect a structure to determine the amount, types, and location of building materials containing asbestos, PCBs, lead, or other harmful substances. This guidance does not apply to the demolition of hurricane damaged but structurally sound buildings.
This guidance remains in effect through December 31, 2005, and applies only to areas damaged by Hurricane Katrina.
To the extent feasible, efforts should be made to perform the following steps:

Asbestos Safety and Health Topics
As per the Occupational Safety & Health Administration (OSHA) 's website www.osha.gov - Asbestos is well recognized as a health hazard and is highly regulated. An estimated 1.3 million employees in the construction and general industry face significant asbestos exposure on the job. Heaviest exposures occur in the construction industry, particularly during the removal of asbestos during renovation or demolition. Employees are also likely to be exposed during the manufacture of asbestos products (such as textiles, friction products, insulation, and other building materials) and during automotive brake and clutch repair work. OSHA and the Environmental Protection Agency (EPA) asbestos rules are intertwined. The following questions link to information relevant to asbestos in the workplace.

How Is and Was Asbestos Used
How is asbestos used?
Asbestos was mined and used commercially in North America beginning in the late 1800s. Its use increased greatly during World War II (3, 4). Since then, asbestos has been used in many industries. For example, the building and construction industry has used it for strengthening cement and plastics as well as for insulation, roofing, fireproofing, and sound absorption. The shipbuilding industry has used asbestos to insulate boilers, steampipes, and hot water pipes. The automotive industry uses asbestos in vehicle brakeshoes and clutch pads. Asbestos has also been used in ceiling and floor tile; paints, coatings, and adhesives; and plastics. In addition, asbestos has been found in vermiculite-containing consumer garden products and some talc-containing crayons.
In the late 1970s, the U.S. Consumer Product Safety Commission (CPSC) banned the use of asbestos in wallboard patching compounds and gas fireplaces because the asbestos fibers in these products could be released into the environment during use. Additionally, in 1979, manufacturers of electric hairdryers voluntarily stopped using asbestos in their products. In 1989, the U.S. Environmental Protection Agency (EPA) banned all new uses of asbestos; uses established prior to 1989 are still allowed. The EPA also established regulations that require school systems to inspect for damaged asbestos and to eliminate or reduce the exposure to occupants by removing the asbestos or encasing it (2).
In June 2000, the CPSC concluded that the risk of children’s exposure to asbestos fibers in crayons was extremely low (1). However, the U.S. manufacturers of these crayons agreed to eliminate talc from their products. In August 2000, the EPA responded to reports it received about the adverse human health effects associated with exposure to asbestos-contaminated vermiculite by conducting a series of tests to evaluate the extent of the risk. The EPA investigation concluded that the potential exposure to asbestos from some vermiculite products poses only a minimal health risk to consumers. The EPA recommended that consumers reduce the low risk associated with the occasional use of vermiculite during gardening activities by limiting the amount of dust produced during use. Specifically, the EPA suggested that consumers use vermiculite outdoors or in a well-ventilated area; keep vermiculite damp while using it; avoid bringing dust from vermiculite use into the home on clothing; and use premixed potting soil, which is less likely to generate dust.
The regulations described above and other actions, coupled with widespread public concern about the health hazards of asbestos, have resulted in a significant annual decline in U.S. use of asbestos. Domestic consumption of asbestos amounted to about 803,000 metric tons in 1973, but it had dropped to about 2,400 metric tons by 2005 (3, 5).

Mesothelioma: Questions and Answers
Mesothelioma is a rare form of cancer in which malignant (cancerous) cells are found in the mesothelium, a protective sac that covers most of the body's internal organs. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles.
What is the mesothelium?
The mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. The mesothelium produces a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.
The mesothelium has different names, depending on its location in the body. The peritoneum is the mesothelial tissue that covers most of the organs in the abdominal cavity. The pleura is the membrane that surrounds the lungs and lines the wall of the chest cavity. The pericardium covers and protects the heart. The mesothelial tissue surrounding the male internal reproductive organs is called the tunica vaginalis testis. The tunica serosa uteri covers the internal reproductive organs in women.
What is mesothelioma?
Mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum.
How common is mesothelioma?
Although reported incidence rates have increased in the past 20 years, mesothelioma is still a relatively rare cancer. About 2,000 new cases of mesothelioma are diagnosed in the United States each year. Mesothelioma occurs more often in men than in women and risk increases with age, but this disease can appear in either men or women at any age.
What are the risk factors for mesothelioma?
Working with asbestos is the major risk factor for mesothelioma. A history of asbestos exposure at work is reported in about 70 percent to 80 percent of all cases. However, mesothelioma has been reported in some individuals without any known exposure to asbestos.
Asbestos is the name of a group of minerals that occur naturally as masses of strong, flexible fibers that can be separated into thin threads and woven. Asbestos has been widely used in many industrial products, including cement, brake linings, roof shingles, flooring products, textiles, and insulation. If tiny asbestos particles float in the air, especially during the manufacturing process, they may be inhaled or swallowed, and can cause serious health problems. In addition to mesothelioma, exposure to asbestos increases the risk of lung cancer, asbestosis (a noncancerous, chronic lung ailment), and other cancers, such as those of the larynx and kidney.

Reduce Exposure to Asbestos
Steps to Reduce Exposure
It is best to leave undamaged asbestos material alone if it is not likely to be disturbed.
Use trained and qualified contractors for control measures that may disturb asbestos and for cleanup.
Follow proper procedures in replacing wood stove door gaskets that may contain asbestos.
If you think your home may have asbestos, don't panic!
Usually it is best to leave asbestos material that is in good condition alone. Generally, material in good condition will not release asbestos fiber. There is no danger unless fibers are released and inhaled into the lungs.
Do not cut, rip, or sand asbestos-containing materials.
Leave undamaged materials alone and, to the extent possible, prevent them from being damaged, disturbed, or touched. Periodically inspect for damage or deterioration. Discard damaged or worn asbestos gloves, stove-top pads, or ironing board covers. Check with local health, environmental, or other appropriate officials to find out about proper handling and disposal procedures. If asbestos material is more than slightly damaged, or if you are going to make changes in your home that might disturb it, repair or removal by a professional is needed. Before you have your house remodeled, find out whether asbestos materials are present.
When you need to remove or clean up asbestos, use a professionally trained contractor.
Select a contractor only after careful discussion of the problems in your home and the steps the contractor will take to clean up or remove them. Consider the option of sealing off the materials instead of removing them.

What are the Health Effects of Asbestos Exposure
What are the health effects of asbestos exposure?
Exposure to airborne friable asbestos may result in a potential health risk because persons breathing the air may breathe in asbestos fibers. Continued exposure can increase the amount of fibers that remain in the lung. Fibers embedded in lung tissue over time may cause serious lung diseases including: asbestosis, lung cancer, or mesothelioma. Smoking increases the risk of developing illness from asbestos exposure.
Three of the major health effects associated with asbestos exposure include:
Asbestosis – Asbestosis is a serious, progressive, long-term non-cancer disease of the lungs. It is caused by inhaling asbestos fibers that irritate lung tissues and cause the tissues to scar. The scarring makes it hard for oxygen to get into the blood. Symptoms of asbestosis include shortness of breath and a dry, crackling sound in the lungs while inhaling. There is no effective treatment for asbestosis.
Lung Cancer – Lung cancer causes the largest number of deaths related to asbestos exposure. People who work in the mining, milling, manufacturing of asbestos, and those who use asbestos and its products are more likely to develop lung cancer than the general population. The most common symptoms of lung cancer are coughing and a change in breathing. Other symptoms include shortness of breath, persistent chest pains, hoarseness, and anemia.
Mesothelioma – Mesothelioma is a rare form of cancer that is found in the thin lining (membrane) of the lung, chest, abdomen, and heart and almost all cases are linked to exposure to asbestos. This disease may not show up until many years after asbestos exposure. This is why great efforts are being made to prevent school children from being exposed.Exposure to asbestos increases your risk of developing lung disease. That risk is made worse by smoking. In general, the greater the exposure to asbestos, the greater the chance of developing harmful health effects. Disease symptoms may take several years to develop following exposure. If you are concerned about possible exposure, consult a physician who specializes in lung diseases (pulmonologist).
For more information on these and other health effects of asbestos exposure see the Agency for Toxic Substances and Disease Registry's Web site.

For more information on these and other health effects of asbestos exposure see the Agency for Toxic Substances and Disease Registry's Web site.
