Pathogen Reduction for the Modern Age: UV and Near-UV as Disinfection Aids

This presentation will discuss the use of Germicidal UV (and some non-UV) technologies that may be deployed to reduce pathogens in public spaces. Various technological solutions will be explored – reviewing their history of use, discussing how they work, and their effectiveness for typical commercial applications that we see today. Additionally, design considerations and techniques will be discussed in-depth for applying UV disinfection technology safely and effectively, incorporating luminaire concepts to supplement the delivery of general ambient illumination. The presentation will also highlight the most recent advances in UV disinfection technology that offer more targeted capabilities for today’s specific pathogen reduction needs. Learning Objectives:

▶ Recognize the ability and effectiveness of ultraviolet (and some near-UV) sources to reduce pathogens on surfaces and in air and water.

▶ Describe how pathogen reduction with a UV or near-UV source is calculated differently than illumination with a visible light source.

▶ Distinguish various ultraviolet and near-ultraviolet wavelengths for use in occupied or unoccupied spaces and discuss how these technologies may be deployed for the least design-disruptive and most cost-effective manner.

▶ Identify the potential impacts of misapplied ultraviolet and near-ultraviolet sources.
