What constitutes "friable" asbestos?

Friable asbestos refers to asbestos materials that can be easily crumbled, broken, or pulverized by hand pressure. This characteristic is crucial in assessing the risk associated with asbestos-containing materials because friable asbestos can release fibers into the air when disturbed, creating a significant health hazard.

Materials classified as friable are often found in older insulation, ceiling tiles, and sprayed coatings, where they can degrade over time. The ability to easily crumble means that friable asbestos poses a higher risk of exposure compared to non-friable forms, which are more stable and less likely to release fibers unless they are mechanically disturbed or damaged. Understanding this distinction is vital for effective asbestos management and ensuring safety during any demolition or renovation work involving asbestos-containing materials.
