What is the primary characteristic of non-friable materials?

Non-friable materials are defined primarily by their structural integrity and the ability to resist disintegration when dry. This means they remain intact and cannot easily be crumbled or reduced to powder by hand. This characteristic is crucial in asbestos identification and management because non-friable materials are generally considered to pose a lower risk of releasing asbestos fibers into the air compared to friable materials, which can easily break down and release hazardous fibers.

In contrast, other options do not accurately represent the defining traits of non-friable materials. For instance, the idea that non-friable materials are easily reduced to powder is fundamentally opposed to their primary characteristic. The assertion that they are only used in outdoor applications is also misleading, as non-friable materials can be found in a variety of settings, both indoors and out. Lastly, suggesting that non-friable materials are inherently safe without any regulations overlooks the necessary safety protocols that must be observed when handling materials that contain asbestos, regardless of whether they are friable or non-friable. Overall, the correct understanding of non-friable materials is essential for effective monitoring and management of asbestos-containing materials in various environments.
