Breathing zone and general room air measurements were taken and analyzed for chloropentafluoroethane (76153) (Freon 115) and chlorodifluoromethane (75456) (Freon 22) at Koldaire, Incorporated (SIC-7623) in Salt Lake City, Utah, on January 20, 1981. Medical evaluations were conducted on 27 workers. The survey was requested by a union member who developed a neurological illness. The 8 hour time weighted average standards established by ACGIH are 3500 milligrams per cubic meter (mg/m3) for Freon 22, and 6320mg/m3 for Freon 115. Measurements taken were all far below the ACGIH standard. The medical evaluations showed 71 percent of exposed workers complained of dizziness and lightheadedness, compared with 21 percent of nonexposed workers. Palpitations were reported in 36 percent of exposed and none of the nonexposed workers. No other significant differences were found. The authors conclude that a serious chronic health hazard to refrigeration workers exists.
