UV Sterilization Trends in the Healthcare Clinical Setting

Pam Gwynn, Principal Engineer, Life and Health Sciences

Recorded on July 15, 2020

The 2020 Covid-19 pandemic has placed unimagined stress on the healthcare industry. A critical aspect of delivering effective healthcare is access to adequate supplies of sterilized medical devices, personal protective equipment (PPE) and sterilized spaces for patient treatment. Sterilization technologies using ultraviolet (UV) radiation are showing significant promise in the efforts to increase the scale of safe and effective sterilization. From contained UV sterilization chambers to standalone UV devices and systems installed in operating rooms and patient containment areas, UV sterilization technologies are increasingly providing a safe and environmentally preferred method for achieving and maintaining contaminant-free equipment and supplies.  In this panel discussion, we will discuss concerns with exposure to UV radiation, typical application of UV devices, risk groups associated with UV and standards used for evaluation of these types of sterilization devices used in a health care environment.

  • What is UV Sterilization?
  • Potential Safety Risks Associated with UV Sterilization Technologies
  • Testing and Labelling of Systems and Equipment Used for UV Sterilization
  • UL’s Approach to the Testing and Listing/Recognition of UV Sterilization Systems
