Which scenario indicates potential significant damage to friable ACBM?

Frequent usage by building occupants is a scenario that indicates potential significant damage to friable Asbestos-Containing Building Materials (ACBM). When these materials are disturbed regularly through usage, the likelihood of their degradation increases. This disturbance can lead to the release of asbestos fibers into the air, posing a health risk to occupants and maintenance workers.

In comparison, normal environmental wear and tear typically occurs over a long period and may not significantly impact the integrity of the materials unless exacerbated by frequent physical interaction. Occasional inspections by maintenance staff, while necessary for safety, are not likely to disturb the materials to the extent of causing damage. Low humidity conditions are generally less concerning for friable ACBM since moisture can often help keep such materials intact; dryness can actually lead to greater fragility but is not directly indicative of damage itself. Therefore, regular use by occupants is the most pertinent factor in identifying significant damage potential.
