Providing your workforce with respiratory protection (N95) against respiratory hazards such as the virus that causes COVID-19 is a safety standard regulated and enforced by the Washington Department of Labor and Industries (L&I). Fit testing ensures the N95 respirator will filter out 95% of the airborne virus when used correctly.

Jan 20 2021· N95 snorkel masks with high-efficiency filters and snorkel masks with powered-air purifying respirators were tested. Respiratory filtration ratios were collected for each step and averaged to obtain an overall workplace protocol fit factor. Failure was defined as either an individual filtration ratio or an overall fit factor below 100.

Masks were tested with 3D adaptors to mount regular bacterial-viral ventilator filters when available or with snorkel openings covered with N95/FFP2 cloth. Results: Modified masks performed reasonably well on the fit test comparable to regular N95/FFP2 masks. Not all ventilator filters are equally protective.

Apr 20 2021· The modified full-face snorkeling mask was tested during 9 otolaryngologic and 15 thoracic surgery procedures. The device demonstrated very good overall vision quality with some limitations regarding lateral vision and almost no difficulties in usability. Water condensation into the mask was absent in almost every case.

Medical masks and respirators are essential during the COVID-19 outbreak. However there are important differences between them. Masks are loose-fitting while respirators are tight-fitting around the nose and mouth. As repirators create a seal to prevent air leakage they are considered a form of respiratory protection.

Objectives: N95 filtering facepiece respirators (N95 FFRs) and surgical masks are comprised of multiple layers of nonwoven polypropylene. Tight-fitting N95 FFRs are respiratory protective devices (RPDs) designed to efficiently filter aerosols. During the COVID-19 pandemic health care workers (HCWs) throughout the world continue to face shortages of disposable N95 FFRs.
