UV Light, or Ultraviolet light, is made up of three wavelengths of light: UVA, UVB, and UVC.
The longest wavelength, UVA, is everywhere, able to penetrate the atmosphere, and makes up 95% of all the UV rays from the sun. This type of UV light can cause sunburns, skin aging, and even skin cancer. UVB is the second longest wavelength and, even though it is mostly absorbed by the ozone layer, it can still be harmful to humans. The shortest wavelength, UVC, is unable to penetrate the Earth’s atmosphere and is fully absorbed by the ozone layer.
Surfacide UV technology utilizes the UVC wavelength, which measures from 0 to 280 nanometers. Optimal UV light disinfection or its peak germicidal UVC wavelength is 254nm.
No person should be directly exposed to UV-C light. However, following proper safety protocols, Surfacide UVC lights can be operated safely. Surfacide also incorporates safety motion sensors that are placed on the entryways of the areas being disinfected to avoid unintended exposure to UV-C light.
