What classification of asbestos material is more likely to release fibers into the air?

Friable materials are classified as those that can easily crumble or break apart under pressure or when disturbed. This characteristic is particularly significant in the context of asbestos, as friable asbestos is more likely to release fibers into the air when it is disturbed, for example during renovation or demolition activities. When the integrity of these materials is compromised, tiny asbestos fibers can be released into the environment, leading to potential inhalation and associated health risks.

In contrast, non-friable materials, which are more stable and less likely to generate airborne fibers, do not pose the same level of risk in normal conditions. Sealed materials, which are treated to prevent exposure to asbestos fibers, and deposited materials, which may refer to asbestos collected in specific locations, are also unlikely to release fibers if their condition remains intact. Therefore, the distinguishing factor for friable materials is their propensity to become airborne during regular handling or disturbances, making them a primary concern for asbestos management and health safety protocols.
