It is also a common sterilization method for plastic vaccine bottles. However, ethylene oxide is flammable and explosive, so the following points need to be paid attention to during the sterilization process:

1. The ethylene oxide sterilizer must be placed in a well-ventilated place. Do not place it near the fire source. In order to facilitate maintenance and regular maintenance, 51cm of space should be reserved on each side (including the top) of the ethylene oxide sterilizer. Special exhaust ducts should be installed and completely isolated from other exhaust ducts in the sterilization site.
2. Items to be sterilized must be thoroughly cleaned. Note that they cannot be cleaned with saline. There should be no water droplets or too much water on the sterilized items to avoid dilution and hydrolysis of ethylene oxide. If the packaging material is changed, it should be verified to ensure the reliability of the sterilization of the sterilized items.

4. Sterilization treatment: It should be carried out in accordance with the operating instructions of the manufacturer of the ethylene oxide sterilizer; select the appropriate sterilization parameters according to the type, packaging, loading volume and method of the plastic vaccine bottle.
The above points should be paid attention to when the plastic vaccine bottle is sterilized by ethylene oxide. In addition, in order to ensure the safety and effectiveness of the sterilization, the ethylene oxide sterilization equipment must be regularly cleaned, repaired and debugged in accordance with the manufacturer's requirements.
