Why Is Asbestos Dangerous?

What Is A Popcorn Ceiling?

Asbestos fibers  most often enter the body is through breathing . Several of the fibers become trapped in the mucous membranes of the throat and nose where they can then be removed, but some can get into the lungs, or, if swallowed, into the digestive tract. Asbestos is most hazardous when it is friable, meaning it is easily crumbled by hand, releasing fibers into the air. Sprayed on asbestos insulation is highly friable.  Asbestos-containing ceiling tiles, floor tiles, undamaged laboratory cabinet tops, shingles, fire doors, siding shingles, etc. will not release asbestos fibers unless they are disturbed or damaged in some way.

Asbestosis

Asbestosis is a serious, chronic, non-cancerous respiratory disease. Inhaled asbestos fibers aggravate lung tissues, which cause them to scar. Symptoms of asbestosis include shortness of breath and a dry crackling sound in the lungs while inhaling.  There is no effective treatment for asbestosis; the disease is usually disabling or fatal. Those who renovate or demolish buildings that contain asbestos may be at significant risk, depending on the nature of the exposure and precautions taken.

Lung Cancer

Lung cancer causes the largest number of deaths related to asbestos exposure. The incidence of lung cancer in people who are directly involved in the mining, milling, manufacturing and use of asbestos and its products is much higher than in the general population.  People who have been exposed to asbestos and are also exposed to some other carcinogen — such as cigarette smoke — have a significantly greater risk of developing lung cancer than people who have only been exposed to asbestos.

Mesothelioma

Mesothelioma is a rare form of cancer that most often occurs in the thin membrane lining of the lungs, chest, abdomen, and (rarely) heart. About 200 cases are diagnosed each year in the United States. Virtually all cases of mesothelioma are linked with asbestos exposure. Approximately 2 percent of all miners and textile workers who work with asbestos, and 10 percent of all workers who were involved in the manufacture of asbestos-containing gas masks, contract mesothelioma. People who work in asbestos mines, asbestos mills and factories, and shipyards that use asbestos, as well as people who manufacture and install asbestos insulation, have an increased risk of mesothelioma. So do people who live with asbestos workers, near asbestos mining areas, near asbestos product factories or near shipyards where use of asbestos has produced large quantities of airborne asbestos fibers.
