Ethylene oxide Mixture with CO2
The ethylene oxide-carbon dioxide 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.
The second group of fumigants is highly toxic and includes methyl bromide, ethylene oxide, sulfuryl fluoride, phosphine, and hydrogen cyanide.

Ethylene oxide (EtO) is a colorless gas at room temperature (b.p. 11degC) proven carcinogenic.
It is highly flammable and poses serious explosion hazards when exposed to flame.
With rust present, autoignition temperatures have been reported as low as 140degC; when compressed with air, it results in an explosion.
Ethylene oxide vapor may initiate explosive decomposition without air.
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 must be fixed but cannot withstand higher temperatures.
Applications
Ethylene oxide-based mixtures with carbon dioxide are frequently employed in biomedical settings to disinfect equipment made of single-use plastic for various uses, including hemodialysis, cardiac surgery, autotransfusion, plasmapheresis, and blood filtration.
Ethylene oxide can also effectively defend against microorganisms, spores (five to ten times more potent than regular bacteria), molds and yeasts, and viruses.
The sterilization rate depends on temperature, treatment duration, gas concentration, and humidity levels.
