Category I non-friable asbestos includes which of the following materials?

Category I non-friable asbestos refers to materials that contain asbestos but are in a form that is unlikely to release fibers into the air under normal conditions. These materials are typically solid and can include certain types of roofing materials and floor tiles, which are considered more stable and less likely to be disturbed during regular use or maintenance.

Roofing and flooring materials are well-defined within this category because they are generally applied in such a way that the asbestos fibers remain bound and encapsulated within the product. This characteristic makes them less of a risk compared to friable materials, which can easily be damaged or disturbed, leading to airborne fiber release.

Other materials listed, such as sprayed-on insulation and pipe insulation, fall into the friable category, as they can be easily crumbled and release fibers. Contaminated soil containing asbestos would typically be classified differently and may present a higher risk for exposure, depending on the levels of asbestos and the condition of the soil.
