Beschreibung
Zusammenfassung:	A system for treating articles, preferably with a sterilizing, gas is disclosed. The system includes a chamber into which the articles are received and valves for supplying the sterilizing gas to the chamber and for removing the gas from the chamber after a predetermined time period. The sterilizing gas is generated on site from at least two components, thus minimizing problems in the transportation of the gas to the location. The sterilizing gas generated on site is preferably chlorine dioxide and the two components may be chlorine gas and sodium chlorite. The system includes a programmed microprocessor controller for controlling the valves executing a predetermined sequence of instructions. The predetermined sequence of instructions define a state diagram for the system having a plurality of successive states. In order to provide for system safety, the controller preferably employs a plurality of abort states to which the system returns in the event of a failure. Depending on the nature of the failure, the system automatically moves to the proper abort state.
