The Mine Safety and Health Program is administered in Massachusetts by the Department of Labor Standards in cooperation with the U.S. Department of Labor, Mine Safety and Health Administration. Under 30 CFR Part 56, safety and health standards are required to be in place for all surface metal/non-metal mines throughout the nation. Initial and annual refresher training of all mining employees is required as well (30 CFR Part 46). These requirements apply to the approximately 150 mining operations in Massachusetts. The operations in Massachusetts include sand and gravel pits, crushed stone operations, and quarries. Efforts by Department of Labor Standards are focused on preventing injuries and illnesses by conducting site inspections and providing training for employees.
