Which condition must be assessed for ACM?

The physical condition of Asbestos Containing Materials (ACM) is crucial for assessment because it directly impacts the potential for asbestos fibers to become airborne and pose health risks. When evaluating ACM, inspectors need to determine whether the material is intact or deteriorating. This assessment includes looking for signs of damage, wear, or any physical changes that could lead to fiber release.

For instance, if the ACM is in good physical condition—such as being well-maintained and securely encapsulated—the risk of exposure is considerably lower. However, if the material is damaged, friable, or otherwise compromised, it can release asbestos fibers into the air, increasing the risk of inhalation and associated health hazards.

In contrast, while weight, chemical composition, and age of the material may provide useful information in specific contexts, they do not directly indicate the immediate risks associated with ACM in terms of immediate safety and exposure risks. Therefore, assessing the physical condition is paramount in determining how to manage and mitigate risks associated with ACM.
