A mapping technique for displaying the geographic concentration of potential worker exposure to hazardous chemicals was developed. Computer files from the NIOSH National Occupational Hazard Survey were searched for specific instances where the chemical of interest was identified during factory site visits. Companies in which the chemical was present were classified by their four digit Standard Industrial Classification code. Names and addresses of similar companies were extracted from the Dun and Bradstreet computer files. The records were organized by county and analyzed using a computerized statistical analysis system. A cartography system at the National Oceanic and Atmospheric Administration was used to produce a map of the continental United States with each county shaded appropriately. Areas containing large numbers of companies similar to those using a given chemical identified during site visits were shaded very dark, and areas less likely to contain significant quantities of the chemical were shaded in lighter half tones. Use of the system for mapping potential exposure to asbestos (1332214) was described. The author concludes that the mapping system can be used to produce maps for each of the 8,000 potential hazardous materials identified during the National Occupational Hazard Survey.
