In response to a request from at Glennwood Range (SIC-3469), Delaware, Ohio, a study was made of possible hazardous working conditions. At this facility 750 employees manufactured consumer gas and electric ranges. Several employees were suffering from skin disorders. Eighty seven of the employees worked in the Enamel Department where the primary responsibility was painting the individual range parts prior to their final construction. Porcelain enamel paints were applied to range parts by either a dipping or flow coat process. The porcelain enamels contained chromium (7440473) in the trivalent state. Oxidizers were added to the enamels, causing the potential for the trivalent chromium to change to a hexavalent state. The skin problems were found mainly among the ground coat line workers who were responsible for hanging parts on hooks to enter a curing oven. Most workers did not wear protective rubber gloves. It was determined that holes had developed in the heating coils of the curing oven, producing open flames. The open flames had caused burn off on the parts, and sharp edges developed on hooks used to hang parts. Samples taken from the hooks used to hang the range parts showed chromium(VI) concentrations of 0.09 to 2.41 micrograms per milligram of sample. Chromium(VI) concentrations in matter scraped from the hooks ranged from 0.3 to 4.4 micrograms/milligram. Sharp edges on the hooks caused abrasions on the hands of the worker, allowing the chromium a direct route of entry beneath the skin surface, causing the ulcerations. The authors conclude that a health hazard existed from exposure to chromium. The authors recommend measures for oven maintenance and worker protection.
