Oudejans, L., K. Ratliff, W. Calfee, J. Musante, C. Tomlinson, AND S. Serre. Preliminary Results LA Metro Field Study using Puro Lighting Xe UVC Light for Disinfection of Surfaces. Presentation to LA Metro, Research Triangle Park, NC, August 13, 2020.

Impact/Purpose:

SARS-CoV-2, the causative virus of the CoVID-19 pandemic, is by now a highly studied pathogen, yet consensus is lacking on the effective dose to inactivate/kill this virus on surfaces using UVC light. Dose-response curves are lacking for this virus as well as many surrogates. Information of what doses can be realistically achieved in e.g., a metro car or bus to achieve disinfection are also lacking. This presentation summarizes the preliminary results of a field study in collaboration with LA Metro that measured UVC doses at various locations in a metro car outfitted with UVC light generated devices. It also includes the measurement of recovered MS2 viruses on stainless steel coupons that were exposed to this UVC light at various locations in the metro car. This information provides a first guidance on the selection of the SARS-CoV-2 surrogate for UVC disinfection research and the anticipated UVC doses. Both are of high relevancy to transportation authorities and other entities including the general public that may consider UVC light disinfection of their spaces.

Description:

Presentation of preliminary results to LA Metro on the disinfection of surfaces with MS2 viruses (a surrogate to SARS-CoV-2) in the presence of UVC light.
