Underwriter Laboratories (UL) recently released “UL 8802 Outline for Investigation of Germicidal Systems” in response to the increased use of ultraviolet (UV) radiation for germicidal purposes in the lighting marketplace. Addressing the need for safe evaluation of germicidal systems, this document establishes requirements for permanently mounted, or fixed, germicidal systems for unoccupied, nonresidential spaces. The outline defines the safety considerations and criteria for evaluating germicidal systems that include UV emitters, switches, sensors, and other controls acting as site or equipment safeguards.
In order to assess the safety of germicidal systems and minimize the risks of overexposure to UV energy, which can cause serious personal injury, a combination of requirements have been pulled together into one document covering:
- Installation and operating instructions of UV germicidal systems
- Requirements for documentation and training of instructed operators and qualified service persons
- Equipment and site safeguards, and criteria for safe shutdowns
- Labeling and instructions for proper equipment use, personal protective equipment and safety precautions
- Photobiological assessment (IEC 62471) and ozone testing (where applicable)
