What is the predominant color and structure of Amosite asbestos?

• A. Brown; long and curly.
• B. White; long and straight.
• C. Blue; long and straight.
• D. Brown/tan; long and straight.

Answer: (D)

Amosite is a brown asbestos. Its fibers are long and straight, often appearing as straight, needle-like bundles rather than curly. This combination—brown/tan color with long, straight fibers—fits Amosite precisely, and helps distinguish it from other types: chrysotile is white with curly fibers, while crocidolite is blue and also has long, straight fibers.
