Ethylene oxide gas is commonly used to sterilize medical devices and equipment. It is a flammable gas with a slightly sweet (ether-like) odor. If the gas 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.

Wear the protective gloves, gowns, and masks your healthcare facility provides. Also, follow your employer's system for keeping track of your exposure to gases.

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

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 before eating, drinking, or smoking.

Ethylene oxide can affect the skin, eyes, respiratory system, kidneys, adrenal glands, and nervous system. The exposed person may experience headache, vomiting, diarrhea, difficulty breathing, and weakness. It may also cause sterility, spontaneous abortions, birth defects, and cancer.
