Respirator Fit Testing:
Prepare today for tomorrow’s exposure
The following video presentation is intended for informational purposes and does not represent itself as a piece of definitive instructional material. The target audience includes health care professionals, first responders and others preparing to take a quantitative respiratory fit test.
The individuals appearing in the live action fit testing sequences were participants in a real time event, and may or may not have successfully completed the exercise. The donning of masks as depicted in these sequences may not always be consistent with published recommendations, which require straps to be near the top of the head and near the level of the ear for best fit. In all circumstances, the manufacturers' and government regulatory agency recommendations regarding the placement of masks should always be read before donning the respective devices(s).
Questions regarding surgical masks vs. close fitting masks reflect the best available information at the time of this production, and the viewer is advised to keep abreast of current literature for the most useful recommendations.
The comments and illustrations contained in this video are in no way an endorsement of the TSI PortaCount device or of the manufacturers of any masks or other devices used in this production.
