What is the primary concern about friable asbestos?

Friable asbestos is primarily a concern because it can easily release fibers into the air. This characteristic makes it particularly hazardous, as airborne asbestos fibers can be inhaled, leading to serious health issues such as asbestosis, lung cancer, and mesothelioma. Friable asbestos is defined as material that can be crumbled, pulverized, or reduced to powder by hand pressure, making it more likely to become airborne during disturbance.

This property differentiates friable asbestos from non-friable asbestos, which is more stable and less likely to release fibers unless it is damaged. Non-friable types are typically found in products like vinyl tiles or concrete, where the asbestos fibers are bound within a matrix that provides added stability.

Understanding this risk underscores the importance of proper handling, abatement, and preventive measures when dealing with materials that could contain friable asbestos, particularly during renovations, demolitions, or other activities that might disturb asbestos-containing materials.
