What does it mean if asbestos-containing material (ACM) is described as intact?

When asbestos-containing material (ACM) is described as intact, it signifies that the material remains uncrushed and bound within its matrix. This means that the asbestos fibers are securely enclosed within the material and not exposed or released into the air. An intact condition is crucial because it minimizes the risk of asbestos fiber release, which can pose serious health hazards if inhaled.

Describing ACM as intact usually implies that it is in stable condition, meaning there is no significant damage or degradation that could lead to fiber release. This contrasts with conditions where the material might be crumbled, pulverized, or affected by disturbance, which would indicate a compromised state that may endanger health through potential exposure to airborne asbestos fibers. Therefore, recognizing intact ACM is vital for safe handling and management practices in asbestos remediation and surveillance upon inspection.
