When is asbestos considered to be a danger to people?

Asbestos is considered to be a danger to people primarily when asbestos-containing materials are damaged. This occurs because damage to these materials can release asbestos fibers into the air, where they can be inhaled. When inhaled, these fibers pose significant health risks, including respiratory diseases and cancers such as asbestosis and mesothelioma. It is the airborne fibers that create the immediate health threat, making the condition of the asbestos-containing materials critical in assessing risk.

Other factors, such as improper storage or low concentrations, do not necessarily mean asbestos is immediately hazardous. While low concentrations might suggest a reduced risk, any presence of airborne fibers is still a concern. Similarly, while the use of asbestos in plumbing can be problematic, it is the state of the materials—specifically, if they are damaged—that makes them dangerous. Hence, identifying damage as a high-risk factor highlights the importance of maintaining the integrity of asbestos-containing materials to ensure safety.
