In many workplaces, dust might seem like a mere nuisance, easily swept away or ignored. However, certain types of dust, known as respirable dust, pose serious health risks to workers. Respirable dust consists of tiny particles that can be inhaled deep into the lungs, leading to a range of health problems, from irritation and coughing to chronic conditions like silicosis and lung cancer.

One of the key concerns with respirable dust is its potential to contain harmful substances such as silica, asbestos, coal, and wood dust. These particles, when breathed in regularly over time, can cause irreversible damage to the respiratory system. Recognizing these dangers, the Occupational Safety and Health Administration (OSHA) has established regulations to protect workers from exposure to respirable dust.
