Ethylene oxide also is used to sterilize equipment and plastic devices that cannot be sterilized by steam, such as medical equipment. Vapor forms explosive mixtures with air over a wide range. Neurological disorders and even death have been reported. Ind., 1949, 68, p. 179]. It is obtainable mixed with carbon dioxide in the proportion of one part ETO to nine parts CO2 by weight or lt or 12 percent ETO with nonflammable halogenated hydrocarbon refrigerant gases. Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. Burns readily. Chem., 1950, 42, p. 1251].
