Why is exposed surface area significant in asbestos risk assessment?

The significance of exposed surface area in asbestos risk assessment primarily relates to the potential for fiber release. When friable asbestos material is visible, it indicates that the material is more susceptible to disturbance, whether through natural erosion, human activity, or interaction with the environment. This increased exposure means that more fibers can be released into the air, posing a higher risk of inhalation or contact for individuals in the vicinity. Identifying and evaluating the exposed surface area helps assess potential risks and formulate safety measures to minimize asbestos exposure effectively. This understanding is crucial for protecting occupational health and ensuring appropriate remediation or management strategies are implemented.
