The Federal Coal Mine Health and Safety Act of 1969 specifies that the concentration of respirable coal mine dust shall be measured using an MRE sampling instrument or a suitable device approved by the Secretary of the Interior and the Secretary of Health, Education, and Welfare. Title 30, Code of Federal Regulations, Part 70, specifies that the flow rate of the MRE instrument shall be 2.5 liters per minute and the flow rate of the other approved personal coal mine dust sampling devices shall be 2.0 liters per minute. The Federal Mine Safety and Health Amendments Act of 1977, which amends the 1969 Act, mandates that these procedures continue. This informational report presents the standard procedures used by the Mining Enforcement and Safety Administration (MESA) for calibration of the MRE and currently approved personal samplers and associated equipment and maintenance procedures for the equipment.
