Respirable dust refers to tiny particles in the air that are small enough to be inhaled into the lungs. These particles can come from various sources, including construction sites, mining activities, and industrial processes. Because of their small size, respirable dust can pose health risks, leading to respiratory issues and other health problems. Monitoring and controlling respirable dust is important for workplace safety and public health. Organizations often use air quality assessments and dust control measures to minimize exposure. Regulations, such as those set by the Occupational Safety and Health Administration (OSHA), help ensure that dust levels remain within safe limits.
