What material type does not need to be removed before demolition when it is Class I non-friable ACM?

Class I non-friable asbestos-containing materials (ACM) refer to materials that are unlikely to release asbestos fibers into the air under normal conditions and are not easily crumbled or pulverized. Therefore, certain materials can remain in place during demolition if they are intact and not disturbed.

Packing materials, particularly when they are non-friable, are designed to be stable and not readily release fibers. If these materials are in good condition and pose no risk of disturbance, they do not require removal prior to demolition. This allows for a more efficient demolition process while maintaining safety regarding asbestos exposure.

On the other hand, popcorn ceilings, floor tiles, and insulation can often fall under a different classification. These materials may be more susceptible to fiber release, especially if they are deteriorating or being disturbed during demolition, thus requiring proper abatement procedures before proceeding with demolition work.
