What does the term 'friability' refer to concerning asbestos insulation?

The term 'friability' specifically refers to the ease with which asbestos insulation can crumble into fibers. This characteristic is crucial as it directly impacts the potential release of asbestos fibers into the air, which poses significant health risks when inhaled. When materials are friable, they can easily become airborne, increasing the likelihood of exposure to asbestos-related diseases, such as asbestosis and mesothelioma. In contrast, materials that are not friable remain more intact and pose less of a risk in terms of fiber release. Understanding friability is essential for assessing the safety and management of asbestos-containing materials in any setting.
