Personal air samples were analyzed for nickel (7440020), tantalum (7440257), ozone (10028156), cadmium (7440439), and fluorides and a general work area environmental air sample was analyzed for 1,1,2- trichloro-1,2,2-trifluoroethane (76131) and relative humidity was measured at Fisher and Porter Company, (SIC-3824), Warminster, Pennsylvania, on April 15 and 21, 1980. The evaluation was requested by the management on behalf of rotometer assembly employees who complained of headaches, nose bleeding and watering of the eyes. Concentrations of ozone, nickel, tantalum, fluoride and cadmium were below the lower limit of detection. The concentration of 1,1,2-trichloro-1,2,2-trifluoroethane was 5.4 milligrams per cubic meter (mg/CuM), well below the permissible criteria of 7600mg/CuM. On April 21, 1980, the relative humidity ranged from 21 to 30 percent and complaints were received of dryness and burning of the eyes and dryness of the throat. On April 15, the humidity ranged from 28 to 33 percent and health complaints were minimal. The author concludes that there is no hazard from overexposure to air contaminants. He recommends that the relative humidity be increased to maintain it in the comfort zone of 30 to 70 percent.
