What Is Asbestos?
Asbestos is a general name given to several naturally occurring minerals (some of which are still mined today) which exhibit useful properties, and thus have been utilized in building materials. The most common of these properties is thermal insulation and thermal stability.
Friable vs. Non-Friable
In the asbestos industry, you will hear the terminology “friable” and “non-friable” used to describe asbestos containing material. If the material is referred to as “friable,” this means that the material can be disturbed or destroyed (reduced to a powder) by light pressure. “Non-friable” material, on the other hand, is asbestos containing material that is too hard to be disturbed by light pressure – it would, alternatively, take mechanical grinding, sanding, or other extreme pressure to reduce the material to a powdered state.
