Which of the following materials is categorized as Category I Non-Friable ACMs?

• A. Frayed rope and fabric
• B. Fresh paint chips
• C. Packing, gaskets, resilient floor coverings and tar in asphalt roofs
• D. Loose insulation

Answer: (C)

Category I non-friable ACMs are asbestos-containing materials that stay bound and do not crumble into powder under normal handling. The material described—packing and gaskets, resilient floor coverings, and tar in asphalt roofs—fits this category because these products are bound in a matrix and are not easily pulverized by hand, so they pose a lower risk of releasing fibers unless they are cut, damaged, or otherwise disturbed. The other items don’t fit as Category I non-friable ACMs: frayed rope and fabric tend to be friable and can crumble to release fibers; loose insulation is typically friable and easily releases fibers; paint chips can contain asbestos but are not the standard examples listed as Category I non-friable ACMs in most classifications.
