Final answer:
The Sterrad sterilization system most commonly uses hydrogen peroxide as its sterilizing agent. This method is preferred because hydrogen peroxide is effective in killing a broad range of microorganisms and decomposes into harmless by-products, making it environmentally friendly.
Step-by-step explanation:
The Sterrad sterilization system most commonly uses hydrogen peroxide as a chemical solution. This system relies on low-temperature hydrogen peroxide gas plasma for sterilization, which is effective in killing a wide range of microorganisms, including spores. The system can sterilize sensitive medical equipment that cannot withstand high temperatures. The effectiveness of this sterilization method is due in part to the fact that hydrogen peroxide is an oxidizing agent, releasing free radicals that destroy vital cell components of microorganisms.
Additionally, the use of hydrogen peroxide in plasma form allows for the penetration of the sterilant into areas that are often difficult to reach by liquid disinfectants. While other agents like ethylene oxide and glutaraldehyde are also used for sterilization, the Sterrad system capitalizes on the advantages of hydrogen peroxide, such as its rapid breakdown into water and oxygen, leaving no toxic residues and reducing the risk of environmental pollution.
