A few days ago, the Global Lighting Association released a position statement, "Quantitative Guidance for Airborne Pathogen Inactivation by Ultraviolet Germicidal Radiation (UVGI) Technology." This guidance is very important right now in the fight against COVID-19.
UVGI air disinfection technology is a recognized method for reducing the risk of infection caused by several airborne diseases such as measles, influenza and tuberculosis. Therefore, UVGI becomes a key tool for reducing indoor air pollution caused by the SARS-CoV-2 virus. Pathogen inactivation theories and mathematical models are also well documented in the existing UVGI literature. The position statement outlines methods for quantifying the microbial decontamination ability of UVGI products in test chambers. These results can be used to determine the product's ability to disinfect in real-life situations such as classrooms, offices, hospital wards, restaurants, and more.
China Lighting Association is a member member of the Global Lighting Association. Since the outbreak of the epidemic in 2020, the association has attached great importance to the development of ultraviolet sterilization technology, and has continued to participate in the compilation of "Quantitative Guidelines for Inactivation of Airborne Pathogens by Ultraviolet Germicidal Radiation (UVGI) Technology" and "Guidelines for Safe Use of UV-C Disinfection Equipment" , completed the Chinese translation of the technical publication "Bactericidal UV-C: Light Sources, Products and Applications" by the Global Lighting Association. The guidelines released this time are mainly aimed at UV air purifiers, UV upper air disinfection lamps and other products. It is a further development on the basis of "Guidelines for the Safe Use of UV-C Disinfection Equipment" and "Bactericidal UV-C: Light Sources, Products and Applications" Technical achievements. At present, based on the three technical reports that have been released, the China Photographic Association is organizing the development of standards for ultraviolet sterilization products and measurement methods. Industry technicians are welcome to actively participate in the association's related standardization work and jointly promote the ultraviolet sterilization industry. scientific development.
