What is the average diameter range of airborne asbestos fibers?

The average diameter range of airborne asbestos fibers is typically found in the range of 0.5 - 10 micrometers. However, airborne asbestos fibers that are most commonly monitored and are of critical concern to occupational hygiene typically fall into the breadth of 1 - 5 micrometers. This size range is particularly relevant because fibers within this diameter can remain suspended in the air for prolonged periods, increasing the likelihood of inhalation and potential health risks associated with asbestos exposure, such as asbestosis and lung cancer.

Fibers at this size are small enough to bypass the body's natural defense mechanisms in the respiratory system, further exacerbating health risks. The ability to remain airborne and penetrate deep into the lungs makes monitoring these sizes crucial in occupational environments where asbestos is present.

Choosing a diameter outside of this commonly accepted range would not accurately reflect the most hazardous sizes typically encountered in workplace settings.
