Which of the following types of asbestos fibers is most commonly found?

Chrysotile is commonly known as white asbestos and is the type of asbestos fiber that is most frequently encountered in various materials and products. It constitutes a significant majority of asbestos used throughout history, accounting for approximately 90% of all the asbestos consumed. This widespread use arises from its favorable properties, such as flexibility, chemical resistance, and high tensile strength, which make it suitable for sealing, insulation, and various construction materials.

In contrast, the other types of asbestos fibers, including amosite, crocidolite, and anthophyllite, are less prevalent. Amosite, known as brown asbestos, and crocidolite, known as blue asbestos, have been used in some industrial applications, but their overall usage is minimal compared to chrysotile. Anthophyllite, being the least common, has had very limited commercial applications. This discrepancy in usage highlights why chrysotile is recognized as the most commonly found asbestos fiber.
