What type of construction is considered friable ACBM?

Friable Asbestos-Containing Building Material (ACBM) refers to materials that can be easily crumbled, pulverized, or reduced to powder by hand pressure. This classification is critical because friable materials pose a higher risk of asbestos fiber release into the air, increasing the potential for exposure during repair, removal, or disturbance. Understanding how friable materials behave is essential for ensuring safe handling and compliance with regulations.

Materials that are solid and unbreakable do not fall into the category of friable ACBM, as they do not readily release fibers when disturbed. Similarly, materials frequently painted over may not necessarily exhibit friability, depending on their composition. Lastly, the usage of the material in various settings—be it school or non-school environments—does not determine its friability status. The key factor lies in the material's ability to be crumbled or reduced to powder, which is why identifying it correctly as friable ACBM is crucial for safety and regulatory compliance in construction and demolition projects.
