Ethylene Oxide Sterilization Device

Ethylene oxide is a colorless and odorless gas that has been used for sterilization since the 1960s. It is slightly heavier than air, flammable and explosive.

Ethylene oxide sterilization is the sterilization process at low temperature and at standard times with pressure, humidity and ethylene oxide gas.

How is Ethylene Oxide Sterilization Used?

It works as a sterilant, which reacts with the cell wall of microorganisms, causing irreversible alkalinization. It is compatible with medical materials. It is often preferred for plastic materials that are especially sensitive to moisture and heat. In ethylene oxide sterilization, some gases are combined to minimize the explosive and flammable properties of ethylene oxide gas.

What are the Advantages of Ethylene Oxide Sterilization?

• It does not harm the materials.

• It is very easy to both implement and follow.

• Compatible with most medical instruments.

• Suitable for sterilization of plastic and lumen instruments.

• It is effective against all microorganisms.

• It can be used for all medical equipment and surgical instruments that are sensitive to moisture and heat.

• Easily penetrates into packaged materials.

Considerations When Using Ethylene Oxide Sterilizers

There are things to consider when using ethylene oxide sterilization equipment and sterilizers.

• Safety procedures including all steps of ethylene oxide should be given in writing to all personnel and all necessary information must be taught to the personnel.
• Safety interlocks should be checked for gas leakage before starting the process.
• If there is an abnormal situation in the ventilation room after the sterilization process is over, the room should be ventilated.
• Waste ethylene oxide concentrations should be continuously and regularly monitored.
• Precautions should be taken to prevent leakage in the ethylene oxide storage area.
• Maintenance and controls of the ethylene oxide device should be done regularly.
• Only authorized persons should be able to enter the ethylene oxide area.
• Emergency and maintenance personnel should be informed of the potential hazards and gas leakage into the work area should be prevented.
• Hazard warning signs should be hung and entry and exit to the work area should be under control.
• Personnel authorized to enter the ethylene oxide area should be informed of the potential hazards and have received appropriate training in safe use.
