• Description:
  Environmental and personal air samples were analyzed for trichlorotrifluoroethane (76131) hydrochloric-acid (7647010), and nickel (7440020) and copper (7440508) dusts at the United States Assay Office (SIC-9999), South San Francisco Annex, in San Francisco, California on August 20 and October 8, 1980. Medical interviews were also conducted. A representative of the American Federation of Government Employees, Local 51, requested the evaluation on behalf of approximately 42 affected workers. None of the samples for trichlorotrifluorethane exceeded the California Occupational Safety and Health Administration (CaL-OSHA) standard of 1000 parts per million (ppm). Hydrochloric-acid vapors ranged from undetectable to 0.03ppm compared with the CaL-OSHA standard of 5ppm. Copper dust concentrations were below the CaL-OSHA standard of 1 milligram per cubic meter (mg/cu m). No nickel dust was detected. Symptoms of sleepiness, dizziness, and skin irritation were reported by several workers. The authors conclude that a health hazard from overexposure to trichlorotrifluorethane, hydrochloric-acid, and nickel or copper dust did not exist at this facility, and that the reported medical symptoms resulted from direct skin contact with wet or dry coins and intermittently high concentrations of trichlorotrifluoroethane. They recommend the use of protective gloves, proper cleaning and drying of coins prior to transportation, and evaluation of the ventilation system.
