ethylene oxide (EtO)

Ethylene oxide (EtO) is a colorless, flammable gas used primarily to sterilize medical equipment and to produce chemicals like antifreeze and plastics. It’s effective at killing bacteria, viruses, and fungi, making sterilization possible without heat. However, EtO is toxic and a potential carcinogen, so its use requires strict safety measures. Workers handling EtO and facilities emitting it must follow regulations to minimize health risks. Because of its hazardous nature, proper management and ventilation are essential to protect both human health and the environment.
