The National Electrical Manufacturers Association (NEMA) Lighting Systems Division endorses the Global Lighting Association (GLA) position statement on germicidal ultraviolet irradiation.
According to GLA, germicidal ultraviolet irradiation is a proven methodology for inactivating viruses on solid surfaces, in water, and air. As such, it is expected to be a useful tool in the fight against the COVID-19 pandemic.
UV-C is a category of ultraviolet light with wavelengths between 100-280 nanometers and is the most effective UV light for disinfection. UV-C devices are considered safe if they meet the applicable safety requirements provided in the International Electrotechnical Commission and/or Underwriters Laboratories Standards or other regional safety requirements.
“The position statement provides current safeguards to avoid human exposure to irradiance hazards and excessive ozone concentrations while NEMA and other Standards developing organizations work on comprehensive technical Standards for the safe operation of these devices,” says NEMA Lighting Systems Division Industry Director Karen Willis.
