Title Control technology for ethylene oxide sterilization in hospitals
Bibliographic information National Institute for Occupational Safety and Health, 4676 Columbia Parkway, Cincinnati, OH 45226, USA, Sep. 1989. 167p. Illus. Bibl.
Abstract In this study nine steriliser control systems were evaluated in 8 hospitals in the USA. Three emission sources accounted for most of the ethylene oxide released into the environment: release from the air gap at the connection of the drain to the pump outlet; opening of the steriliser door at the completion of a cycle; load transfer procedures. Exposures can be controlled to a ceiling limit of 5ppm and to average less than 0.1ppm for a full shift. In-chamber aeration substantially eliminates any exposure and is considered the best control. Other control measures include cycle modification, local ventilation above the steriliser door, a ventilated enclosure around the drain and general ventilation.
