Table showing Pneumoconiotic agents: Percent of exposures exceeding designated occupational exposure limits by type of mining, MSHA inspector and mine operator samples, 1979-2003

- indicates incalculable field.SIC - Standard Industrial ClassificationPEL - permissible exposure limit Note:  The NIOSH REL for respirable coal mine dust of 1.0 mg/m3 was adopted in September 1995.
