Exposure to halothane, ethrane (13838169), and nitrous oxide (10024972) in the operating rooms of Weld County Hospital (SIC-806) in Greeley, Colorado was determined on June 29, 1978. The evaluation was requested by the hospital management on behalf of the 30 workers in the operating rooms. Measured halothane concentrations ranged from below the limit of detection to 1.73 parts per million (ppm); 2 of 28 samples exceeded the NIOSH recommended concentration of 0.5ppm. Ethrane concentrations ranged from undetectable to 16ppm; 3 of 28 samples exceeded the NIOSH recommended concentration of 0.5ppm. Nitrous oxide concentrations ranged from 5 to 65ppm; 8 of 34 samples exceeded the NIOSH recommended concentration of 25ppm. The author concludes that the concentrations of anesthetic gases in the operating rooms did not pose an immediate danger to employees. The author recommends that anesthetic equipment be checked and maintained regularly, the scavenging system of the anesthetic cart be improved, and equipment be properly maintained.
