What are the disinfection methods for the clean pass box?

The disinfection methods of the clean pass box mainly include ultraviolet disinfection, chemical disinfectant disinfection, and ozone disinfection. The following is the specific introduction:
Ultraviolet disinfection
Principle: Ultraviolet disinfection utilizes the ultraviolet rays emitted by ultraviolet lamps to destroy the DNA or RNA structure of microorganisms, rendering them unable to reproduce or survive, thereby achieving the purpose of sterilization and disinfection.
Operation method: Install ultraviolet lamps in the pass box. Generally, turn on the ultraviolet lamps for more than 30 minutes before and after the item transfer. Make sure that the ultraviolet lamp can cover every corner inside the transfer window to ensure the disinfection effect.
Precautions: Ultraviolet rays are harmful to human skin and eyes. When turning on ultraviolet lamps, people should avoid looking directly at the ultraviolet light source and ensure that no one stays inside the transmission window. In addition, the irradiation intensity of the ultraviolet lamp should be checked regularly. When the intensity is lower than the specified value, the lamp tube should be replaced in time.
Chemical disinfectant disinfection
Principle: Using chemical disinfectants such as hydrogen peroxide, peracetic acid, sodium hypochlorite solution, etc., these disinfectants can destroy the cellular structure and biological activity of microorganisms through oxidation, alkylation, and other actions, achieving the effect of disinfection and sterilization.
Operation method: Disinfection can be carried out by wiping or fumigation. When wiping, use a clean cloth dipped in an appropriate amount of disinfectant solution to carefully wipe the internal surfaces of the transfer window, including the top plate, side plates, bottom plate, door, and item placement rack, etc., to ensure that every part is wiped. When fumigation and disinfection are carried out, the disinfectant should be placed into the transfer window in accordance with the prescribed dosage and method, and the doors and Windows should be closed to allow the disinfectant to evaporate inside the transfer window and maintain its effect for a certain period, which is generally 1 to 2 hours.
Note: Select the appropriate chemical disinfectant based on the types of microorganisms that may exist inside the transfer window and the degree of contamination, as well as the material of the transfer window. When in use, strictly follow the instructions of the disinfectant for preparation and application. Pay attention to the concentration, action time, and usage method of the disinfectant. After disinfection, it is necessary to ensure that the residual disinfectant is fully removed. Sterile water can be used for wiping or ventilation to avoid affecting the health of the items being conveyed and the personnel. At the same time, chemical disinfectants have certain corrosiveness and irritation. Operators should wear protective gloves, masks, and other protective equipment properly.
Ozone disinfection
Principle: Ozone has strong oxidizing properties and can destroy the cell membranes, nucleic acids, etc. of microorganisms, thereby killing bacteria, viruses, and other microorganisms.
Operation method: Disinfection is carried out by generating ozone through the ozone generator installed in the pass box. When the transfer window is not in use, turn on the ozone generator to allow the ozone to reach a certain concentration inside the transfer window and maintain it for some time. Usually, the disinfection time is 30 to 60 minutes.
Ozone poses certain hazards to the human body. After disinfection is completed, it is necessary to ensure that the ozone in the transfer window is fully decomposed or discharged before people can enter. At the same time, the working condition of the ozone generator should be checked regularly to ensure its normal operation and guarantee the disinfection effect.
