HazCom: Ethylene Oxide

Ethylene oxide gas is commonly used to sterilize equipment. But if it isn’t fully evaporated during aeration procedures, it can damage skin and other body tissue. You’ll be trained to work with this gas safely and to use the sterilization and aeration equipment correctly. Ask your supervisor if you have any questions.

Sterilizing equipment

Use PPE (personal protective equipment)

Wear the protective gloves, gowns, and masks your health care facility provides. Also follow your employer’s system for monitoring your exposure to gases.

Transport safely

Transfer equipment quickly and safely from the sterilizer to the aeration chamber. Keep equipment at arm’s length and away from your breathing area.

Follow aeration safety steps

Aeration allows gas to evaporate completely under controlled conditions in an approved chamber. Never open the door before the process is finished.


Wash your hands

Wash your hands before eating, drinking, or smoking.

Know the risk

Ethylene oxide can affect the skin, respiratory system, and nervous system. It may also cause sterility, birth defects, and cancer.
