What does "friable" refer to in relation to asbestos materials?

"Friable" in relation to asbestos materials refers to those that can easily be crumbled or turned into powder when dry. This characteristic is crucial because friable asbestos poses a higher risk to health due to the potential for fibers to become airborne during disturbance or deterioration. When asbestos material is friable, it can release harmful fibers into the air, increasing the likelihood of inhalation and subsequent health risks, including lung disease and cancer.

Understanding the properties of friable versus non-friable asbestos is essential for inspectors and handlers, as it informs the necessary safety protocols for management, removal, or remediation. Non-friable asbestos, on the other hand, is more stable under normal conditions and does not release fibers easily, making it less of an immediate health threat when undisturbed.
