UL has issued UL 8802 Outline of Investigation for Germicidal Systems.  The outline covers requirements for the safety evaluation of germicidal systems where surfaces in an unoccupied area are exposed to ultraviolet (UV) energy at an exposure dose that would otherwise pose a risk of personal injury to occupants. System components include:

  • UV emitters (equipment that produces visible light or UV radiation)
  • UV switches and sensors
  • Other controls acting as site or equipment safeguards on UV systems

The UL 8802 Outline of Investigation is to be used in conjunction with CSA C22.2 No. 250.0/UL 1598, the Standard for Luminaires to address applicable risk of shock, risk of fire and risk of personal injury due to factors other than UV overexposure. The outline includes additional requirements to minimize the risk of personal injury due to UV overexposure. Installation and operating instructions are considered an integral system component. UL 8802 includes requirements for proper labeling and instructions, along with documentation for personal protective equipment and training for instructed operators and qualified service persons. Safeguards of both the equipment and the site, combined with criteria for safe shutdowns, are also required.

This outline of investigation only addresses permanently mounted, or fixed, equipment intended to be installed and operated in non-residential locations. Equipment that emits electromagnetic energy with wavelengths greater than 700 nanometers or less than 200 nm are not addressed in this document.

Germicidal systems evaluated using this new outline of investigation are covered under UL Certification Category Number (CCN) IFHH.

As with all UL Standards, current UL subscribers have electronic access to the outline. To purchase a copy of the UL 8802 Outline of Investigation, visit https://www.shopULstandards.com
