Health Hazard Evaluation Determination Report No. HE 78-61-497, Camp Hill Animal Hospital, Camp Hill, Pennsylvania

摘要

Breathing zone and general area samples were taken for halothane (CAS 151-67-7) at the Camp Hill Animal Hospital (SIC-0742) in Camp Hill, Pennsylvania and anesthesia machines were evaluated for leakage on April 27 and 28, 1978. An evaluation request came from the employer to evaluate the potential for exposure to 6 employees and to provide information on the chronic effects of halothane. Personal breathing zone and general area samples were obtained. Eight of 9 personal breathing zone samples ranging from 4 to 21 parts per million (ppm) halothane exceeded the recommended criteria of 2ppm. Area samples averaged 1.3 to 4.7ppm. Gas leakage from gas machines ranged from 2 to over 60ppm. The author concludes that a health hazard due to halothane exposure does exist at this facility. A scavenging system should be used to recirculate unused gas, anesthetic gases should be used sparingly, equipment should be checked routinely for leaks or loose connections, and ventilation should be improved.
