The FDA has issued a safety communication about risks of ultraviolet light exposure from a hand-held ultraviolet-C (UVC) wand. UVC light can cause damage to skin and eyes, and devices that produce UVC light should be designed to prevent injury to users. Unfortunately, manufacturing defects or poor design can put users at risk. If you use a UVC device and develop skin or eye burns, please report this to the FDA.
Because of the danger of injury if a UVC device is used improperly or has a manufacturing defect, it is generally safer to clean surfaces using household cleaners or disinfectants. The Centers for Disease Control (CDC) has more information on how to safely clean and disinfect your home.
