![]() Because mercury is toxic even in small amounts, extreme caution is needed in cleaning a lamp that has broken and in disposing of the lamp.Įffectiveness: The effectiveness of UVC lamps in inactivating the SARS-CoV-2 virus is unknown because there is limited published data about the wavelength, dose, and duration of UVC radiation required to inactivate the SARS-CoV-2 virus. UVC can degrade certain materials, such as plastic, polymers, and dyed textile.Ozone inhalation can be irritating to the airway. If you have experienced an injury associated with using a UVC lamp, we encourage you to report it to the FDA. ![]() Never look directly at a UVC lamp source, even briefly. Direct exposure of skin and eyes to UVC radiation from some UVC lamps may cause painful eye injury and burn-like skin reactions.The risk may increase if the unit is not installed properly or used by untrained individuals. Risks: UVC lamps used for disinfection purposes may pose potential health and safety risks depending on the UVC wavelength, dose, and duration of radiation exposure. Q: Is it safe to use a UVC lamp for disinfection purposes at home?Ī: Consider both the risks of UVC lamps to people and objects and the risk of incomplete inactivation of virus. UVA is also implicated in skin aging and risk of skin cancer. UVA: UVA radiation is less hazardous than UVB radiation but is also significantly (approximately 1000 times) less effective than either UVB or UVC radiation at inactivating other SARS viruses.UVB is known to cause DNA damage and is a risk factor in developing skin cancer and cataracts. However, it is less effective than UVC at doing so and is more hazardous to humans than UVC radiation because UVB radiation can penetrate deeper into the skin and eye. ![]()
