Safeopedia Explains Asbestos-Containing Material (ACM)

Asbestos is the name for a particular group of minerals containing many small fibers. It only becomes a risk to health when inhaled as a fine dust. If inhaled this dust sticks to the inside of your lungs and can lead to breathing difficulties and lung cancer. The risk of disease is directly related to the amount of exposure. Asbestos materials have been popular because of exceptional fire-resistant, insulating and reinforcing properties. Some examples are sprayed on fireproofing, linoleum, roofing materials, ceiling tiles, wall and ceiling plaster, mastic and floor tile, troweled plaster, boiler or piping insulation, gasket material, transite shingles and others. There are several types of asbestos covered by ACM including chrysotile, amosite, crocidolite, tremolite, anthophyllite, actinolite and any of these that have been treated or altered.
