Occupational diseases are health conditions that arise as a result of exposure to harmful substances or hazardous conditions in the workplace. These diseases can develop over time due to prolonged exposure to chemicals, noise, or physical stressors. Common examples include asbestosis, caused by inhaling asbestos fibers, and carpal tunnel syndrome, resulting from repetitive hand movements. Preventing occupational diseases involves implementing safety measures, such as proper ventilation, protective equipment, and regular health screenings. Employers are responsible for ensuring a safe work environment, while employees should be aware of potential risks associated with their jobs. Awareness and education are key to reducing the incidence of these diseases.
