Use of UVC Lighting in COVID-19 Disinfection

The COVID-19 global pandemic has prompted scientists to research protective measures for keeping society safe. One of those studies is on the use of UVC radiation as an innovative method for disinfecting surfaces, air, and liquids in healthcare settings. According to the FDA, “Given the current outbreak of Coronavirus Disease 2019 (COVID-19), [. . .] consumers may be interested in purchasing ultraviolet-C (UVC) lamps to disinfect surfaces in the home or similar spaces”. (FDA, 2021) These “Germicidal” UVC radiation emitting lamps have been effectively used for decades to reduce the spread of pathogens. Studies now show that 222nm UVC lamps efficiently and safely inactive airborne human coronaviruses when used correctly.

 

UVC Radiation Facts

UVC for disinfection works well in healthcare settings for disinfecting surfaces, equipment, operating rooms, and personal protective equipment such as N95 facemasks. UVC disinfection technology employs a type of electromagnetic radiation to destruct bacteria and viruses. This UVC radiation has more energy than light and radio waves, but less radioactive energy than an x-ray or gamma rays. Not only can UVC technology be used in light fixtures to disinfect surfaces, but it can also be used inside air ducts to disinfect the air. UVC radiation is not intended for direct exposure for humans due to risk of injury or burn-like skin reactions. For this reason, UVC technology is reserved for use in empty and unoccupied areas.
