What are the precautions when using the VHP pass box?

When using the VHP transfer window, the following precautions should be taken:
Equipment installation and environment
It should be installed in a clean, dry, and well-ventilated place, free from flammable, explosive, and corrosive gases around it.
The installation location should be convenient for operation and maintenance, and sufficient space should be reserved on both sides of the transfer window to facilitate the entry and exit of items.
Ensure that the installation ground is level to guarantee the stable placement of the transfer window and prevent abnormal operation of the equipment due to uneven ground.
Preparation before use
Check whether the door of the transfer window can be opened and closed normally and whether the sealing rubber strip is intact. If any damage is found, it should be replaced in time to ensure good sealing performance.
Confirm whether the hydrogen peroxide supply system is normal, including the liquid level of the hydrogen peroxide storage tank whether the pipeline connections are tight without leakage, etc.
Check whether the parameter Settings of the control system are correct, such as disinfection time, temperature, humidity, and other parameters. They should be reasonably set according to the actual usage requirements and the characteristics of the items.
Clean the interior of the transfer window to remove debris and dust. A clean damp cloth can be used for wiping. If necessary, a disinfectant can be used for wiping, but it is important to ensure thorough drying after wiping to avoid affecting the disinfection effect of hydrogen peroxide.
Item transfer
The items placed in the transfer window should be clean, dry, and free of obvious contaminants. For items with oil stains, blood stains, or other dirt on the surface, they should be cleaned first before being placed in the transfer window.
Items should be placed reasonably in the transfer window to avoid blocking the air outlet and return air outlet, which may affect the circulation and distribution of hydrogen peroxide gas, and ensure a uniform disinfection effect.
When the transfer window is running the disinfection program, it is strictly forbidden to open the two side doors to avoid damaging the disinfection environment, affecting the disinfection effect, and also potentially exposing personnel to hydrogen peroxide gas, causing injury.
After disinfection is completed, wait for the hydrogen peroxide gas to fully decompose or be discharged before opening the transfer window and door to take out the items to prevent personnel from coming into contact with the residual hydrogen peroxide gas.
Safety protection
Operators should undergo professional training, be familiar with the operation process and safety precautions of the transfer window, and strictly follow the operation procedures.
During the operation of the equipment, operators should avoid staying near the transfer window for a long time to prevent hydrogen peroxide gas leakage from causing harm to the human body. If it is necessary to operate nearby, appropriate protective equipment should be worn, such as protective glasses, masks, gloves, etc.
The transfer window should be equipped with corresponding safety devices, such as hydrogen peroxide leakage alarm devices, door safety interlock devices, etc., to ensure the safe operation of the equipment. In case of emergencies such as hydrogen peroxide leakage, the operation of the equipment should be immediately stopped, the ventilation device should be turned on, personnel should quickly evacuate the site, and corresponding emergency response measures should be taken.
Maintenance and upkeep
Regularly clean and disinfect the transfer window. You can use neutral detergent to wipe the external surface, and the interior should be disinfected regularly according to the usage situation to prevent the growth of microorganisms.
Check the operational status of components such as the hydrogen peroxide spray system, gas circulation system, and control system. If any faults or abnormalities are found, promptly repair or replace the relevant components to ensure the normal operation of the equipment.
According to the recommendations of the equipment manufacturer, replace the hydrogen peroxide filter, seals, and other vulnerable parts regularly to ensure the performance of the equipment and the disinfection effect.
Regularly calibrate and verify the equipment to ensure the accuracy and reliability of the disinfection parameters and guarantee that the disinfection effect meets the requirements.
