What UVC disinfection robots can do
The interest in technologies, like robotic devices performing surface and air sanitation procedures using ultraviolet (UVC) radiation, has increased sharply.
Sanitization protocols play a significant role in preventing and containing the spread of infectious diseases — a reality highlighted during the COVID-19 pandemic.
UVC radiation supplements rather than replaces physical disinfection in the commercial environment. This necessitates comprehensive testing and certification services, and UVC disinfection robot evaluations to published safety requirements. Consequently, UL Solutions designed UL 60335- 2-2019, the Outline of Investigation for Robotic Germicidal Equipment, to do just that.
UVC disinfection robots can contribute to safer environments, including:
- Industrial and commercial buildings
- Hotel rooms and conference spaces
- Transportation facilities and systems
Advancing the safety of robotic germicidal equipment with testing and certification to UL 60335-2-2019
Without this comprehensive set of requirements as a guide, UVC robots may have to rely on assessment to safety standards for luminaires and other electrical equipment, even though such standards may not fully address mitigating the safety and reliability risks of this innovative technology.
UL 60335-2-2019 provides the first set of requirements that specifically addresses UVC disinfection robots. Its holistic approach includes requirements to evaluate the robot base, ultraviolet light exposure, electric safety, UVC radiation effects, sensors, and other critical safety systems.
Voluntary testing to UL 60335-2-2019 can benefit:
- Companies that make robotic germicidal equipment for commercial and similar use.
- University/research institutions.
- Companies specializing in UVC disinfection products.
- Businesses that wish to include UL certification to UL 60335-2-2019 in their purchase requirements for these product types.
