Book Description
This report describes the Mine Inspection Data Analysis System (MIDAS) developed by the Bureau of Mines to analyze the records of industrial hygiene samples collected by the Mine Safety and Health Administration (MSHA) in metal and nonmetal mines. MIDAS is the first system capable of sorting, editing, analyzing, and reporting these data. It is also the first system designed to be used by a number of Government agencies. At present the system contains 225,000 personal and area samples for 61 contaminants in 45 industries. The records date from 1974 to early 1980, and MSHA plans to provide yearly updates to the system. This report presents preliminary analyses of dust exposures and discusses the potential uses and limitations of these data. Analysis of the dust data for 1978 and 1979 showed that bagging had the highest percentage of dust overexposure. Morn than 40 pct of the 1,536 respirable quartz dust, total nuisance dust, and total silica dust samples exceeded the MSHA exposure limit. Other dusty occupations are ranked according to their percentage of overexposure.
