There are two main categories of asbestos: amphibole asbestos and serpentine asbestos. The serpentine asbestos group contains one type of asbestos, chrysotile. The amphibole asbestos group consists of several types of asbestos: amosite, crocidolite, anthophyllite, tremolite, and actinolite.
Crocidolite: Characterized by its straight blue fibers, this type of asbestos is considered the most lethal form of the mineral. This is due to the fact that crocidolite has sharp, needle-like fibers that break off easily and are difficult for the body to expel once inhaled or swallowed.
