What defines "non-friable asbestos"?

The correct choice identifies non-friable asbestos as asbestos that is bound within a matrix. This implies that the asbestos fibers are encapsulated or integrated into a solid material, which makes them significantly less likely to release fibers into the air compared to friable asbestos. Non-friable forms of asbestos can include materials such as asphalt, vinyl flooring, and cement products where asbestos is mixed with other substances, providing stability and reducing the risk of airborne exposure when left undisturbed.

The other options do not accurately describe non-friable asbestos. For example, non-friable asbestos is not easily released into the air (which defines friable asbestos) and is not limited to insulation materials; it can be found in a variety of building products. Additionally, while non-friable asbestos can be handled with safety precautions, it is important to recognize that safe handling practices are still necessary, thus debunking the notion that it can be managed without any precautions.
