Abstract
Abstract Ozone carrying mist is employed to sterilize the interior of an enclosure including surfaces and objects therein. Closing movement of a movable wall portion of the enclosure actuates timing means and provides substantially simultaneous flows of predetermined amounts of ozone and water which are mixed to form a mist and injected into the enclosure. Electrical circuitry controlled by the timing means then actuates means for exhausting ozone from the enclosure and drying the wetted surfaces therein.
