In response to a request from the Santa Barbara Cottage Hospital (SIC-8062), Santa Barbara, California, an evaluation was made of possible health hazards. Attention was directed in particular to waste anesthetic gases and vapors in the Outpatient Surgery Center and the main operating rooms. A second concern was ethylene-oxide (75218) (EtO) exposures from a gas sterilizer, and samples were taken during operation of this equipment. These samples registered concentrations below the recommended exposure limit (REL) of 0.1 parts per million (ppm) for EtO. Personal and area air samples were collected during surgery and analyzed for nitrous-oxide (10024972) (N2O), halogenated anesthetic agents, and methyl-methacrylate (80626). Only two samples exceeded the NIOSH REL of 25ppm for N2O. Eight samples exceeded the NIOSH REL of 0.5ppm for halogenated anesthetics used in combination with N2O. During the use of surgical cement, two personal samples were taken which contained 0.12 and about half the recommended number of air changes per hour. The authors conclude that contaminant concentrations are maintained below the environmental criteria in most samples, but a potential for overexposure to N2O and forane (26675467) exists. The authors recommend improving general ventilation at the facility, work practices, exposure monitoring, equipment maintenance, and the use of scavenging systems for waste gases.
