Health standards for occupational noise exposure. Mine Safety and Health Administration (MSHA), Labor. Final rule.
This final comprehensive rule replaces MSHA's existing standards for occupational noise exposure in coal mines and metal and nonmetal mines. The final rule establishes uniform requirements to protect the Nation's miners from occupational noise-induced hearing loss. The rule is derived in part from existing MSHA noise standards, and from the Department of Labor's existing occupational noise exposure standard for general industry promulgated by the Occupational Safety and Health Administration (OSHA). As a result of the Agency's ongoing review of its safety and health standards, MSHA determined that its existing noise standards, which are more than twenty years old, do not adequately protect miners from occupational noise-induced hearing loss. A significant risk to miners of material impairment of health from workplace exposure to noise over a working lifetime exists when miners' exposure exceeds an 8-hour time-weighted average (TWA8) of 85 dBA. MSHA expects that the final rule will significantly reduce the risk of material impairment within the mining industry as a whole.
