General area and breathing zone sampling was conducted on May 25, 1978 to measure concentrations of halothane (151677) at the Littleton Veterinary Clinic (SIC-0741) in Littleton, Colorado. An evaluation request came from the management of the clinic on behalf of 5 affected employees. Halothane concentrations measured by solid sorbent tubes ranged from 4.3 to 20.5 parts per million (ppm). Concentrations ranged from 1 to over 50ppm as measured by infrared spectrometry. The authors conclude that a health hazard exists from exposure to halothane. They recommend that exposures should be reduced to below 2ppm during surgical procedures, a scavenging system be installed for the ventilator, fittings be tightened, equipment be checked periodically, the breathing system be pressurized, and the check valves be tested.
