• Coal Worker’s Pneumoconiosis (Black Lung Disease)

    Coal ers' pneumoconiosis (CWP), commonly known as "black lung disease," occurs when coal dust is inhaled. Over time, continued exposure to the coal dust causes scarring in the lungs, impairing your ability to breathe. Considered an occupational lung disease, it is most common among coal miners.
