Asbestos Contractor/Supervisor Practice Exam

Asbestos is a generic name for a group of minerals that form what?

1. Long fibers

2. Short fibers

3. Flat sheets

4. Granular clusters

The correct answer is: Long fibers

Asbestos refers to a group of naturally occurring fibrous silicate minerals that are characterized by their long, thin fibers. These fibers are significant because they possess unique properties such as flexibility, tensile strength, and resistance to heat, which made them popular in a variety of industrial applications. The long fibers also contribute to the hazardous quality of asbestos when they become airborne, as they can be inhaled and lead to serious health issues. The other options do not accurately describe the physical form of asbestos. Short fibers, flat sheets, and granular clusters do not capture the defining characteristics of asbestos fibers, which are elongated and capable of being woven into various materials. Thus, the identification of asbestos as long fibers is crucial in understanding both its industrial applications and the health risks associated with its exposure.
