Investigation of the working conditions in an operating suite of a teaching hospital reveals that one health hazard affecting operating room personnel is probably related to chronic exposure to concentrations of the inhalation anesthetics. The sources of such agents and their distribution in the operating room are discussed. Effective control include: collection of gases and vapors at the anesthetic breathing systems and disposal procedures, or scavenging; low leakage practice by the anesthetist to minimize gas concentrations in the operating room; equipment maintenance for reducing gas leakage; air monitoring to indicate the effectiveness of the control measures. Correct application of these measures yields less than 30 ppm nitrous-oxide (10024972) and less than 0.5 ppm halothane (151677) in the operating room air, representing about 0.005 percent of the anesthetics administered to the patient.
