Coal dust is a fine black powder made up of tiny particles of coal. It is produced during the mining, handling, and transportation of coal. When disturbed, coal dust can become airborne, posing health risks to workers and nearby communities. Inhalation of coal dust can lead to respiratory issues, including coal workers' pneumoconiosis, commonly known as "black lung disease." This condition occurs when coal dust accumulates in the lungs over time, causing inflammation and scarring. Proper safety measures, such as dust control systems, are essential to minimize exposure and protect health.
