What properties of the mineral asbestos make it dangerous

Asbestos is a set of six naturally occurring silicate minerals,[1] which all have in common their eponymous asbestiform habit: i.e. long (roughly 1:20 aspect ratio), thin fibrous crystals, with each visible fiber composed of millions of microscopic "fibrils" that can be released by abrasion and other processes.[2] They are commonly known by their colors, as blue asbestos, brown asbestos, white asbestos, and green asbestos.[3]

Chrysotile is the only known serpentine asbestos form of a mineral, and it accounts for about 95% of asbestos found within U.S. buildings. Common uses of chrysotile asbestos include plaster compounds, drywall, pipe insulation, cement, industrial gaskets, flooring tiles, brake linings and fire barriers.
