Asbestos was said to be "friable" when it is dry can be crushed or ground, thereby reducing the mineral into a powder. The Friable Asbestos to collapse into a powder form of the most dangerous even in the hands of pressure application. However, in a very damaged condition, non-friable asbestos will crumble to powder in a minimal application of pressure. Real danger that occurs when the asbestos destroyed is that it can easily become air born.
Asbestos proved friable as a major threat because of its ability to release large amounts of asbestos fibers into the air when breaking apart. These fibers can enter the lungs when you breathe in, because they can linger in the air like dust or smoke. As a consequence of breathing in the fibers, damage to the lungs can grow over time with a very deadly form of cancer known as mesothelioma.
