What does Category I nonfriable ACM include?

Category I nonfriable asbestos-containing material (ACM) specifically includes asbestos-containing resilient floor coverings and gaskets, as these materials are considered to be in a solid form that is not easily crumbled, pulverized, or reduced to powder. This classification is crucial for understanding how different forms of asbestos are handled and regulated, as nonfriable materials can pose a lower risk of fiber release compared to friable forms.

In the context of building maintenance and asbestos management, knowing that resilient floor coverings and gaskets fall into this category helps determine proper inspection, maintenance, and disturbance protocols. This is particularly important because if these materials are intact and undisturbed, the risk of asbestos fiber exposure is minimized.

Other options refer to materials that do not align with the specific definition of Category I nonfriable ACM. Materials containing less than 1% asbestos do not qualify as ACM under regulatory definitions. Pure asbestos products, being friable by nature, are typically considered higher risk and fall into a different category. Demolition debris that contains asbestos is usually classified according to its state and condition, which may land it into a more hazardous category compared to nonfriable ACM. Understanding these distinctions aids in effective asbestos management practices and compliance with safety regulations.
