What are the safety rules for GUV surface disinfection lamps?

To ensure the safe use of UVGI lamps for surface disinfection, follow these guidelines:

  • All lamps. Workers should place temporary warning signs at access points to the area being disinfected. They should either vacate the area during disinfection or place opaque barriers between the UVGI lamp and room occupants. If these areas are required to be occupied during disinfection and exposures cannot be avoided (e.g., if using a handheld disinfecting UVGI “wand”), then personal protective equipment (PPE) should be used.
  • Low- and medium-pressure mercury lamps, UVGI LEDs, and far UV-C lamps. Workers should wear plastic or glass face shields to protect the eyes and face, nitrile gloves or work gloves to protect the hands, and full-coverage clothing with tightly woven fabrics to protect all other exposed skin.
  • Pulsed xenon arc lamps. Workers should wear welding or cutting goggles to protect the eyes, nitrile gloves or work gloves to protect the hands, and full-coverage clothing with tightly woven fabrics to protect all other exposed skin.
