Which of the following is an example of Category I nonfriable ACM?

• A. Asbestos-containing packings
• B. Asbestos insulation wrap
• C. Spray-applied fireproofing
• D. Loose asbestos fibers

Answer: (A)

Category I nonfriable ACM are materials containing asbestos that, when dry, cannot be crumbled or pulverized by hand pressure. They stay relatively intact during normal handling, which is why they’re put in this category. Asbestos-containing packings are a classic example because they’re tightly packed and resistant to hand pressure, so fiber release is less likely unless the material is damaged or cut in a way that increases exposure.

Spray-applied fireproofing, by contrast, is typically friable or can be crumbled when damaged, so it doesn’t fit Category I. Loose asbestos fibers are friable by nature and not in this category. Asbestos insulation wrap isn’t the standard Category I example; its classification depends on how it’s manufactured and handled, but it does not illustrate the nonfriable, hand-pressure-inert trait as clearly as packings do.
