Abstract
This report describes a statistical analysis of 41,502 respirable quartz dust samples collected from 1974 through 1981 in metal and non-metal mines and mills. The goal of this Bureau of Mines study was to identify commodities and occupations associated with high quartz dust exposure so that future enforcement and research activity can be focused on the high-exposure areas. For this analysis, the Bureau used its computerized Mine Inspection Data Analysis System (MIDAS), which contains data on nearly 350,000 air samples, including data for 61 contaminants in 45 commodities. The samples analyzed were collected by inspectors of the Mine Safety and Health Administration (MSHA). The data were entered into the MIDAS computer and coded according to commodity, occupation, location, and other categorical information. Occupations and commodities with high quartz dust exposure were identified by grouping the data by code categories.
