Ethylene oxide-carbon dioxide mixture (Ethylene oxide Mixture)is a colorless gas with an ether-like odor. Carbon dioxide is noncombustible. Ethylene oxide is flammable. The mixture can asphyxiate by displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. It is used as a fumigant.
Ethylene Oxide “Gas” Sterilization. ETO is a colorless gas that is flammable and explosive. The four essential parameters (operational ranges) are: gas concentration (450 to 1200 mg/l); temperature (37 to 63°C); relative humidity (40 to 80%)(water molecules carry ETO to reactive sites); and exposure time (1 to 6 hours).It is most commonly mixed with CO2 as sterilization gas and used to sterilize instruments with long lumens such as endoscopes and all materials that have to be sterilized but cannot withstand higher temperature.
