• Description:
  A Health Hazard Evaluation investigation was conducted by NIOSH at the chromic-oxide (1308389) producing area (SIC-2819) of the Minnesota Mining and Manufacturing Company, Copley, Ohio, on November 29-30, 1976. The investigation was prompted by a request from an authorized representative of employees to evaluate the potential hazard associated with employee exposure to chromate pigments. Seven affected employees were interviewed and an environmental survey was conducted by obtaining time weighted average and ceiling measurements of employee exposure to hexavalent chromium (7440473) and trivalent chromium. Based on environmental samplings, evaluation of ventilation systems, observations of employee work practices, and available toxicity information it is concluded that employee exposures to noncarcinogenic hexavalent chromium contained in sodium-bichromate (10588019), as measured during the survey, did not constitute a health hazard. All atmospheric levels of hexavalent chromium were below evaluation criteria. Although no standards exist from trivalent chromium, recommendation are made for preventing the release of trivalent chromium dust in the air. Certain employees who had experienced nosebleeds and other hexavalent chromium related problems in the past had not experienced such problems for at least 1.5 to 2 years of work, probably as a result of the installation of local exhaust ventilation to prevent exposure.
