In response to a request from the University Hospital (SIC-8062), Denver, Colorado, an evaluation was made of possible hazardous working conditions at this site. Particular attention was given to waste anesthetic gases and vapors in the surgical operating rooms and in the recovery room. In 19 personal samples the time weighted average concentrations of nitrous-oxide (10024972) (N2O) ranged from less than the limit of detection to 77 parts per million (ppm) with a mean concentration of 17ppm. The NIOSH recommended limit of 25ppm was exceeded in five of 19 samples. Personal breathing samples were collected and sampled for halothane (151677), ethrane (13838169), and isoflurane (26675467). Halothane was detected in seven of 24 samples ranging from 0.09 to 1.6ppm. The NIOSH recommended limit for halothane of 0.5ppm was exceeded in three samples. Ethrane was detected in five samples at 0.06 to 1.5ppm concentration levels, with two exceeding the NIOSH limit of 0.5ppm. Isoflurane was detected in six samples, ranging from 0.06 to 0.99ppm, with three samples exceeding the NIOSH limit of 0.5ppm. The authors conclude that a hazard existed from exposure to anesthetic gases and vapors during some of the procedures. Detailed recommendations regarding specific control procedures, work practices, and monitoring procedures were made.
