What signifies that material has become friable?

The indication that a material has become friable is that it can be pulverized or crumbled by hand pressure. Friability refers to the tendency of a material, often in the context of asbestos-containing materials, to break down easily and become dust-like when handled. This characteristic poses a higher risk for fiber release, which can lead to potential exposure.

When a material is described as friable, it suggests that it is weakened and can deteriorate, increasing the likelihood of asbestos fibers being released into the air. Understanding and identifying friable materials is crucial in asbestos management because they require specialized handling and remediation strategies to minimize health risks. Materials that are intact, secure, or well-maintained do not fall into the category of friable, as they do not easily break apart or degrade under pressure.
