What is a characteristic feature of friable asbestos-containing materials?

Friable asbestos-containing materials are particularly concerning due to their propensity to release asbestos fibers into the air when disturbed. This characteristic feature arises from the fact that friable materials can easily crumble or break apart, which allows fibers to become airborne, posing significant health risks when inhaled.

Asbestos fibers are hazardous because they can lead to serious health issues, including lung cancer, asbestosis, and mesothelioma. Therefore, the potential for these materials to release fibers into the air highlights the importance of careful handling and regulation during any disturbance or removal process. Understanding this characteristic helps emphasize the critical need for safety precautions and proper procedures when working with or around friable asbestos materials.
