In short, Ultraviolet germicidal irradiation can be damaging to eyes, human skin, and plastics. While transmitting UV wavelengths may be able to be used to inactivate certain dangerous pathogens like SARS-CoV-2, which causes COVID-19, UV rays are generally harmful to many parts of our bodies.
Ultraviolet germicidal irradiation for HVAC systems is limited to the area in which it is installed, so there is no danger to anything in your building except microbes and other contaminants that are carried and form buildups within your air systems. You should never touch, expose skin to, or look directly at a UV light when it is turned on, even if you are wearing sunglasses. HVAC contractors and installers should always unplug and disconnect units when working on them. Ensuring the best possible practices surrounding the safety of personnel that comes in contact with the UV lamps implemented in your HVAC infrastructure is essential.
While long-term exposure to UV-C can damage plastic materials, we are proud to provide our customers with UV-C products that provide an ideal balance between germicidal effectiveness without damaging sensitive materials inside of your HVAC system.
