Recently, “UV LED Wind Direction” learned that Guangzhou Baiyun International Airport has introduced a self-powered handrail ultraviolet disinfection device in Terminal 1, which aims to automatically disinfect the passengers' health through ultraviolet rays.
According to related studies, after passengers touched the handrail, the total number of colonies reached 740CFU, which was 70 times that before touching. Earlier, “the 34-year-old staff member in the terminal area of Chengdu Tianfu International Airport who did not leave the province and did not have a close connection was infected with Delta virus. It was confirmed that the virus spread caused by touching the same handrail with the infected family of three.” , To prove the importance of the elimination of elevator handrails, especially during the epidemic.
It is understood that Baiyun Airport has installed a self-powered ultraviolet disinfection device for escalators, which is only 1800g, and uses 265nm wavelength ultraviolet LED radiation to sterilize, destroying the DNA and RNA structure of bacteria and viruses, making it impossible to regenerate and spread.
According to “UV LED Wind Direction”, similar to Baiyun Airport, in June 2021, Hohhot Airport completed the escalator handrail elimination device in accordance with the requirements of the group company’s "Notice on the Promotion of Escalator Elimination Devices in Member Airports", Hohhot Airport Escalator handrails changed from regular disinfection to real-time disinfection.
In August, Beijing Daxing Airport also chose to equip with ultraviolet sterilization device, also using UVC-LED light source, as long as the handrail is running, it will be activated, so that passengers can feel more at ease when using the handrail.
On September 1, the State Council’s Comprehensive Unit for the Joint Prevention and Control Mechanism for the Novel Coronavirus Pneumonia Epidemic issued the “Notice on Further Strengthening the Prevention and Control of the Novel Coronavirus Pneumonia Epidemic”, which emphasized supermarkets, shopping malls, hotels, airports, railway stations, and long-distance passenger terminals. In places where people are dense and mobile, it is necessary to standardize sanitation management, fully clean and disinfect public areas, and increase the frequency of disinfection of high-frequency contact parts.
Escalator infection incidents, policy requirements, and use in many airports all indicate the importance of escalator disinfection. Different from manual cleaning in the past, it can further improve the efficiency of disinfection and block the risk of transmission. In view of the current epidemic prevention methods, the UVC-LED sterilization solution for escalators will be a trend for some time in the future, and it may become a must-have for escalators in public places.
summary
From the market point of view: in daily life, escalators have become a common means of transportation in public places in modern cities. At present, the rubber material of escalator handrails is very absorbent and easy to attach bacteria, and there is a risk of cross-infection if multiple people touch it. In view of the current epidemic prevention methods, the escalator loading UVC-LED sterilization program will be a trend for some time in the future.
From a functional point of view: the introduction of UVC-LEDs in escalators, on the one hand, uses the safety of UVC-LEDs and its small size and long life. It can be installed on the side of the escalator or embedded in the gap. At the same time, the handrails are irradiated at close range by the UVC band with outstanding sterilization effect, and the handrails are disinfected in a purely physical sterilization manner to prevent the spread of bacteria and viruses, to achieve no chemical or heavy metal residues, and to achieve normal handrails when the escalator is running. Chemical cycle disinfection.
