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

The term "friable" in relation to asbestos materials specifically refers to materials that can be crumbled, pulverized, or reduced to a powder by hand pressure. This characteristic is crucial because friable asbestos poses a higher risk of releasing airborne fibers when disturbed, which can be inhaled and lead to serious health issues, including asbestosis and mesothelioma. Understanding this definition helps inspectors assess the condition and potential risks associated with asbestos-containing materials in buildings. Recognizing whether materials are friable influences decisions about handling, remediation, and management practices to ensure safety during inspections and renovations.
