2018-6-28 · gradually been replaced by the direct vapour-phase oxidation process in which ethylene is oxidized to ethylene oxide with air or oxygen and a silver catalyst at 10–30 atm (1– 3 MPa) and 200–300 ºC (Dever et al . 2004 Anon. 2005).
Also it takes longer than steam sterilization typically 16-18 hrs. for a complete cycle. EO gas sterilization is dependent upon four parameters EO gas concentration temperature humidity and exposure time. Each parameter may be varied. Consequently EO sterilization is a complex multi-parameter process.
A placement diagram must be prepared typically by the contract sterilization facility in consultation with the device manufacturer. The diagram must indicate the location of the product with B.I. test samples plus temperature and humidity sensors in the loaded chamber.
The process of sterilization using ETO involves a cycle of preconditioning humidification (40 –60 relative humidification) introduction of gas exposure evacuation of gas and aeration. The cycle typically takes two and a half hours excluding aeration and a further 8–12 h to allow effective desorption of excess ETO

2021-7-16 · The following information although generic in nature is designed to provide basic information on the ethylene oxide sterilization process. The EO sterilization process has been employed by the health care industry to sterilize medical devices since the early 1940s (Griffith and Hall1940 1943)1. Although not as well controlled as the processes of today the anatomy of the process itself remains remarkably similar to the earlier process
418.3.5 Ventilation of Sterilizer Door Area. The system shall be designed to capture the ETO when the door is opened following the completion of the sterilization process. A hood or canopy closed on each end should be installed over the sterilization door. A hood or canopy shall be connected to a dedicated exhaust ventilation system.
