Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE-76-108-365, 1977 Mar; :1-10
Acting on a request received from the management of the Rocky Mountain Manufacturing and Wire Company (SIC-3315), Pueblo, Colorado, to evaluate the exposures of the employees to the various materials used in the wire cleaning department, a Health Hazard Evaluation survey was performed by NIOSH in September 1976 and January 1977 to determine the nature of headaches, skin burns, rhinitis, dermatitis, coughing and sneezing, experienced by the wire cleaners. Based on the environmental data collected during the survey, administration of medical questionnaires to 6 affected workers, observation of work practices, and a review of the literature relevant to the toxicity of the substances used in the work area, it was determined that worker exposures to potassium- permanganate (7722647) and copper-sulfate (7758987) were not toxic under the conditions prevailing at the time of the survey. The respiratory irritation experienced by the workers in the past has been attributed to the presence of acceptable levels of sulfuric- acid (7664939) mist in the air. Recommendations are provided for reducing the exposure of workers to the agents mentioned.
