Hospitals are always on the lookout for ways to reduce the spread of hazardous pathogens, and one of the most effective solutions is the use of ultraviolet (UV) light disinfection. UV-C radiation has been proven to be an effective germicidal agent, capable of eliminating more than 99.9% of all pathogens in a matter of seconds. This makes it an ideal solution for hospitals, as it requires less time and labor than traditional manual cleaning protocols. Studies have demonstrated that UV disinfectants can reduce the transmission of some of the most dangerous superbugs, such as methicillin-resistant Staphylococcus aureus (MRSA), C. difficile, vancomycin-resistant enterococci (VRE), and Acinetobacter.
A study conducted by Duke Health researchers, published in The Lancet, revealed that machines that emit ultraviolet light can reduce the transmission of four of the main superbugs by an accumulated 30%.UV-C technology is particularly useful in places with a lot of traffic and contact, and on surfaces where the biological load is high. It is also beneficial for dental applications, such as resin curing. Smart UVC lamps are perfect for use in laboratories and hospitals, as they have a wavelength range of 200 to 280 nm and can be used to disinfect water and eliminate dangerous microorganisms present in other liquids, surfaces, food products and air. However, more studies need to be done to establish a safe exposure dose standard, especially for 222 nm germicidal lamps. Direct tests are urgently needed for the application of UV-C against COVID-19 infection.
In general, the use of UV-C radiation as a disinfecting tool can overcome its safety problems if doses are standardized and 222 nm UV-C irradiation can be used. When people are seen entering the workspace with UV rays, the AirZing Pro's infrared sensor will turn off the system. This ensures that people are not exposed to dangerous levels of radiation while still allowing hospitals to take advantage of the benefits of UV light disinfection.
