Pneumoconiotic agents: Percent of exposures exceeding the NIOSH recommended exposure limits by major industry division, MSHA inspector and mine operator and OSHA samples, 1979-2003

Pneumoconiotic agents: Percent of exposures exceeding the NIOSH recommended exposure limits by major industry division, MSHA inspector and mine operator and OSHA samples, 1979-2003

REL - recommended exposure limit    PEL - permissible exposure limit    MSHA - Mine Safety and Health Administration    OSHA - Occupational Safety and Health Administration

Note:

From March 1, 1989 to March 22, 1993, the OSHA PELs in force differed from those employed before and after those dates. The NIOSH REL for respirable coal mine dust of 1 mg/m3 was adopted in September 1995. The MSHA respirable coal mine quartz exposure data and the NIOSH REL for respirable quartz cannot be compared to each other because they are based on different sampling criteria.

See Appendix for more information.
