About this Course

The IES offers Educational Webinars throughout the year, purposefully spanning a broad range of topics and speaker expertise. The Introduction to Ultraviolet and Visible Radiation Disinfection was a live webinar, now available as an archived webinar and CEU course.

Description: Topic experts Dr. David Sliney and Richard Vincent will discuss the science, applications, guidelines, potential, and concerns regarding Ultraviolet and Visible Light Disinfection. Many manufacturers are making claims that cannot be substantiated. David and Richard will take you through what we know, what we don’t know and what you should avoid. Specific topics will include upper room germicidal UV application, surface decontamination, and UV tools and guidelines.

Learning Objectives:

By the end of this course learners will be able to...

1. Identify and understand the four metrics that the CIE denotes for measuring germicidal dosing.  
2. Learn the three levels of UV light and their various effects on living organisms.   
3. Understand and describe the concept of upper room germicidal UV disinfection. 
4. Recognize the current and potential role of ultraviolet and visible light in healthcare spaces.
