Document: The copyright holder for this preprint (which was not peer-reviewed) is the . https://doi.org/10.1101/2020.04. 14.20062810 doi: medRxiv preprint We note that in these previous studies, testing was performed only on static mannequins using three fitting tests, compared to our use of a human model and the OSHA fit testing protocol that utilizes eight fitting tests including dynamic maneuvers such as turning the head side-to-side, upand-down, talking, and bending over. These dynamic fitting maneuvers could have revealed fitting inadequacies caused by UVGI that were not present on static mannequin testing.
