What is asbestos? Asbestos is the name given to a group of naturally occurring fibrous minerals that are resistant to heat and corrosion. Because of these properties, asbestos has been used in commercial products such as insulation and fireproofing materials, automotive brakes, and wallboard materials.
Asbestos can be divided into two basic groups, serpentine and amphibole, which differ in their physical characteristics. Serpentine asbestos develops in a layered or tiered form, whereas amphibole asbestos has a chain-like structure. Identification. Asbestos is generally made up of fiber bundles which easily separate into long, thin fibers. Positive identification of a specific fiber type requires microscopic analysis and examination. All asbestos fibers are hazardous to human health. Asbestos Types. There are six types of asbestos minerals that occur naturally within the Earth's environment. The Environmental Protection Agency (EPA) has classified the types as such: Chrysotile: Chrysotile is one of the most common and most dangerous forms of asbestos found within our Earth.
