On Tuesday, July 23, NIOSH will host an interactive webinar about a recent study that assessed the fluctuation between bivariate panels used in respirator fit-testing. According to NIOSH, the study tested five N95 filtering facepiece and five elastomeric respirators with N95 filters on three different 40-member even-subject-distribution panels and three different 35-member U.S. respirator user population-based panels. Researchers performed two ambient aerosol inward leakage tests on each respirator while the subjects performed several exercises, including normal breathing, deep breathing, turning the head from side to side, moving the head up and down, reciting prepared text, reaching for the floor and ceiling, and grimacing. NIOSH researchers determined variability between panels by computing an estimate of the distribution of the inward leakage percentage.
Presenters Christopher Coffey, PhD, and James (Terry) Wassell, PhD, will discuss the study results and webinar participants will be able to ask questions and comment on the test panels. Registration is required and those who wish to participate in the webinar must register by July 19. Space is limited to 100 participants.
