Coal Workers’ Health Surveillance Program (CWHSP)
• The Federal Coal Mine Health and Safety Act of 1969, amended in 1977
• To develop improved health and safety standards to protect the health and safety of the Nation’s coal and other miners
Coal Workers’ Health Surveillance Program (CWHSP)
• Federally mandated worker medical monitoring program for underground coal miners
• Eligible miners can obtain periodic chest radiographs
Purpose of CWHSP
• Early detection and prevention of coal workers’ pneumoconiosis (CWP)
• Provide health information to miners
• Study the causes and consequences of respiratory diseases associated with coal mining
• Surveillance (e.g., monitor trends and patterns)
