The Federal Viewpoint (MESA).

NIOSH 1982 Oct:6-12
The federal viewpoint regarding using diesel equipment in underground coal mines was discussed. The functions of the Mining Enforcement and Safety Administration (MESA) were summarized. MESA was empowered under the Federal Coal Mine Health and Safety Act of 1969 and the Federal Metal and Nonmetallic Mine Safety Act of 1966 to enforce regulations designed for protecting the health and safety of all miners in the United States. MESA also provided technical support and educational and training programs that promote health and safety within the mining industry. Activities of MESA pertaining to using diesel equipment in underground mines were described. The response to a request made by MESA to NIOSH on the health significance of operating diesel equipment was discussed. In the response, NIOSH expressed concern about the effects of combined exposure to diesel exhaust and dust, as standards exist only for individual exposures to coal dust, nitrogen oxides, and other gases and vapors present in diesel exhaust. In response to this, MESA sent a bulletin to all coal mine operators to inform them of NIOSH's position and the fact that the current standards for coal dust and the individual components of diesel exhaust may not completely protect against combined exposure. It was noted that MESA and NIOSH are conducting a joint epidemiological study on the effects of long term exposure to diesel exhausts. MESA regulations for using diesel equipment in underground mines were discussed. Air quality in underground mines was considered. It was noted that inadequate ventilation has the greatest adverse impact on air quality in mines with diesel equipment. It was suggested that special emphasis needs to be placed on ventilation and control equipment for removing and diluting exhaust gases in underground mines. A transcript of a question and answer session was provided.
