The information known about ethylene oxide (EtO) has changed over time. A hazardous air pollutant, the latest updates from EPA’s National Air Toxics Assessment shows that ethylene oxide is a more potent carcinogen than originally thought; it is 60 times more toxic to children and 30 times more toxic to adults. 

Ethylene oxide emissions can be reduced by removing ethylene oxide sterilization units and replacing sterilization needs with an alternative sterilization method, outsource to a facility using an alternative sterilization method, or to an air permitted facility using ethylene oxide sterilization; increase control of fugitive emissions from ethylene oxide sterilization; or eliminate the use of products that contain ethylene oxide and its derivatives in manufacturing or industrial processes.
