Which of the following is NOT a type of asbestos?

Fiberglass is not a type of asbestos; it is a different material entirely. Asbestos is a group of naturally occurring silicate minerals known for their heat resistance, strength, and insulating properties. There are several types of asbestos, including chrysotile, which is the most common and also referred to as "white asbestos," amosite, known as "brown asbestos," and crocidolite, known as "blue asbestos."

Fiberglass, on the other hand, is made from extremely fine fibers of glass and is primarily used as an insulation material or in manufacturing various products, but it does not belong to the asbestos mineral group. Understanding the distinction between these materials is important, especially for workers in industries related to insulation and construction, as asbestos has significant health risks associated with exposure.
