Sterilization can also be achieved using ethylene oxide (ETO) gas. This process was created in the 1950s by the US military [4] and is used on items that cannot withstand the high temperatures of steam sterilization. ETO sterilization takes far longer than steam sterilization and is hazardous to workers, so alternative methods were created in ...

Ethylene oxide (EO, EtO) gas treatment is one of the common methods used to sterilize, pasteurize, or disinfect items because of its wide range of material compatibility. It is also used to process items that are sensitive to processing with other methods, such as radiation (gamma, electron beam, X-ray), heat (moist or dry), or other chemicals.
The odor threshold for these gases is above the PELs and for ethylene oxide it is 500 ppm, approaching that of the IDLH. [1] Odor is thus inadequate as a monitoring technique. Continuous gas monitors are used as part of an overall safety program to provide a prompt alert to nearby workers in the event that there is a leak of the sterilant gas ...
Ethylene oxide de-sorber: The aqueous stream resulting from the above scrubbing process is then sent to the ethylene oxide de-sorber. Here, ethylene oxide is obtained as the overhead product, whereas the bottom product obtained is known as the glycol bleed .
The desired results are established in terms of specifications for outcome of the process. Qualification of systems and equipment is therefore a part of the process of validation. Validation is a requirement of food, drug and pharmaceutical regulating agencies such as the US FDA and their good manufacturing practices guidelines. Since a wide ...
Equipment used in aseptic processing of food and beverages must be sterilized before processing and remain sterile during processing. [1] When designing aseptic processing equipment there are six basic requirements to consider: the equipment must have the capability of being cleaned thoroughly, it must be able to be sterilized with steam, chemicals, or high-temperature water, sterilization ...
Each sterilization cycle uses less than 18g of 100% EtO, hence economic value is gained when every corner of a traditional EtO chamber type sterilizer that relies on tanks containing pounds of EO need not be filled. [citation needed] Andersen's unit-dose, gas diffusion method is widely used where small quantities of goods require sterilization.
