Hazardous Air Pollutants: Ethylene Oxide

Ethylene oxide is a flammable, colorless gas used to make other chemicals that are used in making a range of products, including antifreeze, textiles, plastics, detergents and adhesives. Ethylene oxide also is used to sterilize equipment and plastic devices that cannot be sterilized by steam, such as medical equipment.

EPA recently updated its risk value for ethylene oxide and is working with industry, and state, local and tribal air agencies to address this chemical.
