Technical Assistance Report No. TA-78-69, Social Security Administration, Richmond, Indiana.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, TA 78-69, 1979 Jan; :1-7
Environmental air samples were analyzed and employees were interviewed at the Social Security Administration district office (SIC-9441) in Richmond, Indiana, on October 17, 1978, to determine the cause of employee complaints to stuffy air, difficulty in breathing, and tired eyes. The evaluation was requested by the management on behalf on 22 exposed workers. The only substances detected in air samples were carbon-monoxide (630080) at 8 parts per million (ppm) and mineral-spirits (8032324) at 19 milligrams per cubic meter (mg/Cu m). Concentrations were well below NIOSH recommendations of 35ppm for carbon-monoxide and 350mg/Cu m for mineral-spirits. Samples analyzed for bacteria and fungus showed only normal flora with no overgrowth of identifiable pathogens. Except for complaints of stuffy air, employees had few other symptoms in common that could be attributed to the environment. The investigators conclude that a health hazard did not exist at the time of the investigation. They recommend improvements in ventilation and employee training in the proper use of toner solutions used in copying machines.
