Hydrogen peroxide is a common disinfectant and sterilizing agent. It is often used in hospitals and other medical facilities for sterilization purposes.

- Properties of Hydrogen Peroxide
Hydrogen peroxide is a colorless liquid that is soluble in water. It is non-toxic and safe to handle, but it can cause irritation to the eyes and skin if not handled properly. It has a strong oxidizing property, which makes it effective in sterilization.
-
- Types of Hydrogen Peroxide
Hydrogen peroxide is available in different concentrations, including 3% and 6%. The higher concentration is more effective in sterilization, but it may also cause more damage to living tissues. Therefore, it should be used under strict guidance and according to the recommended dosage.

- Methods of Using Hydrogen Peroxide for Sterilization
3.1 Surface Sterilization
Surface sterilization using hydrogen peroxide can be applied to disinfecting equipment, tables, floors, walls, etc. It can effectively kill pathogenic bacteria without affecting the surface texture of the materials being disinfected. When using hydrogen peroxide for surface sterilization, the surfaces should be wiped dry beforehand and allowed to dry for 10-15 minutes after disinfection.
3.2 Gaseous Sterilization
Gaseous sterilization using hydrogen peroxide can be achieved by generating gaseous hydrogen peroxide in an autoclave or chamber and exposing it to high temperature and pressure conditions. The hydrogen peroxide vapor reacts with microorganisms on the surface of the target items to achieve sterilization. This method is suitable for sterilizing items that cannot be immersed in water or are difficult to handle, such as precision instruments, electronic components, etc. When using hydrogen peroxide for gaseous sterilization, the temperature and pressure should be strictly controlled to ensure that the sterilization effect is optimal.
3.3 Liquid Sterilization
Liquid sterilization using hydrogen peroxide can be achieved by immersing items in hydrogen peroxide solutions or spraying hydrogen peroxide solutions onto the surface of items. This method is suitable for sterilizing items that can be immersed in water or are easy to handle, such as medical equipment, surgical instruments, etc. When using hydrogen peroxide for liquid sterilization, the concentration and immersion time should be strictly controlled to ensure that the sterilization effect is optimal.

- Precautions for Using Hydrogen Peroxide for Sterilization
4.1 Handle with Care
Hydrogen peroxide is a strong oxidizing agent and should be handled with care to avoid contact with eyes or skin. If contact occurs, rinse immediately with water and seek medical attention promptly.
4.2 Storage Properly
Hydrogen peroxide solutions should be stored in a cool, dark place away from flammable materials or metal products. The bottle should be tightly sealed and avoid exposure to light and heat. Hydrogen peroxide solutions may undergo decomposition over time and should not be used after expiration date specified on the bottle label.
4.3 Usage Restrictions
The usage of hydrogen peroxide solutions should be carried out strictly according to the recommendations specified on the bottle label to ensure safe use and maximum effectiveness. Solutions of higher concentration are more powerful in oxidizing capacity but also more dangerous, so they should not be used for any purpose without strict guidance or professional assistance. It should also not be used on living plants or animals, as it may cause serious harm to their tissues and organs.
