Background
Ethylene Oxide is a gas at room temperature used in chemical manufacturing and as a sterilizing agent for medical equipment and a fumigating agent for spices. Human exposure occurs in occupations involving contact with the gas in production facilities and hospitals that sterilize medical equipment. EtO can also be inhaled by residents living near production or sterilizing/fumigating facilities.
