What kind of vibration is considered a risk factor for disturbing ACM in schools?

Construction-related vibrations are considered a significant risk factor for disturbing asbestos-containing materials (ACM) in schools because the activities associated with construction can generate strong vibrations that may jar or break the integrity of materials containing asbestos. When these materials are disturbed, they can release harmful asbestos fibers into the air, leading to exposure and potential health risks for students and staff.

Foot traffic typically does not produce vibrations strong enough to disturb ACM, although it can contribute to wear and tear on materials over time. Musical vibrations are generally not impactful in the context of damaging ACM, as they tend to be less forceful and more rhythmic. Environmental vibrations, such as those from traffic or natural events, are less likely to specifically lead to the disturbance of asbestos-containing materials compared to the targeted and often intense vibrations from construction activities. Therefore, construction-related vibrations pose a more immediate and substantial risk for disturbing ACM in a school environment.
