What is the cut point for inhalable dust?

Inhalable dust refers to particulate matter that can be inhaled into the respiratory system, primarily the upper airways and lungs. The cut point for inhalable dust is typically established at 100 micrometers. This figure is significant because it defines the size of the particles that are capable of being inhaled, which is crucial for assessing exposure risk in various occupational settings.

Particles that are smaller than 100 micrometers have a higher likelihood of being inhaled and entering the respiratory tract, leading to potential health impacts. Understanding this cut point is essential for developing effective workplace safety measures and for accurately monitoring dust levels in the environment. Establishing thresholds for inhalable dust helps industrial hygienists to evaluate exposure limits and implement appropriate controls to minimize health risks associated with dust inhalation.
