||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.
