New York State Asbestos Investigator Practice Exam

Which type of asbestos is known for having a flexible form?

1. Amphibole

2. Crocidolite

3. Serpentine

4. Chrysotile

The correct answer is: Serpentine

Chrysotile, also known as white asbestos, is recognized for its flexible and long, curly fibers. This unique structure contributes to its ability to be woven into textiles and other materials, which has historically made it popular in various applications. Its flexibility allows chrysotile to be more easily manipulated during manufacturing processes compared to other types of asbestos, leading to its widespread use in products like insulation, roofing, and automotive brakes. While amphible, crocidolite, and serpentine types also exist, they do not exhibit the same level of flexibility as chrysotile. For instance, amphibole asbestos, which includes types like tremolite, actinolite, and amosite, typically possesses straight, needle-like fibers that can be more brittle. Crocidolite, often referred to as blue asbestos, has a similar rigid structure, making it less flexible. The serpentine group, to which chrysotile belongs, consists of a softer and more flexible form of asbestos. Understanding these properties is crucial for effectively addressing safety and handling standards regarding asbestos materials, particularly in the context of investigations and remediation efforts.
