What is a Category 1 non friable, and Category 2 Non Friable via NESHAP?

• A. non friable materials including packing, gaskets, resilient floor covering, and asphalt roofing products, ACM products not in category 1 (usually cementitious products)
• B. Friable materials
• C. Category 2 Non Friable materials only
• D. Category 1 non friable materials only

Answer: (A)

NESHAP divides nonfriable asbestos-containing materials into two categories based on how easily they can be crumbled or pulverized by hand pressure. Category I nonfriable are materials that do not readily crumble under hand pressure, such as asphalt roofing products and many resilient floor coverings. Category II nonfriable includes ACM that are not in Category I and are typically cementitious, as well as other nonfriable items like packing and gaskets that could become friable under disturbance. The option listed reflects this structure by naming nonfriable materials including packing, gaskets, resilient floor covering, and asphalt roofing products, and then noting ACM products not in Category I (usually cementitious products) as the other category. This aligns with how NESHAP distinguishes the two classes and explains why that choice is the best answer.
