What are the two major classifications of asbestos?

The distinction between serpentine and amphibole forms the basis for the two major classifications of asbestos. Serpentine asbestos, which includes chrysotile, is characterized by its curly fibers and is the most commonly used type of asbestos. This form is found in a range of materials due to its flexibility and resistance to heat.

On the other hand, amphibole asbestos encompasses a group of minerals that have straight, needle-like fibers, including amosite, crocidolite, and others. These amphibole varieties are less commonly used compared to serpentine but pose significant health risks due to their shape, which facilitates deeper inhalation into the lungs.

This classification is essential as it informs regulatory measures and health risk assessments related to asbestos use and exposure. Understanding the differences between these two types helps inspectors and health professionals evaluate the potential dangers associated with asbestos-containing materials effectively.
