– Direct exposure of skin and eyes to UVC radiation from some UVC lamps may cause painful eye injury and burn-like skin reactions. – Some UVC lamps generate ozone. Ozone inhalation can be irritating to the airway. – UVC can degrade certain materials, such as plastic, polymers, and dyed textile. – Some UVC lamps contain mercury.
