Background A major concern among health care experts is a shortage of N95 filtering facepiece respirators (FFRs) during a pandemic. One option for mitigating an FFR shortage is to decontaminate and reuse the devices. The focus of this study was to de

Do industrial N95 respirators meet the requirements to be used in healthcare? - A possible solution to respirator shortages during the next pandemic

Autor: Matthew Horvatin, Samy Rengasamy, Deborah Sbarra

Publikováno v: Am J Infect Control

Shortages of surgical N95 respirators (surgical N95 FFRs) can occur during a pandemic. To understand if industrial N95 FFRs have FDA required fluid penetration resistance and flammability, five NIOSH approved N95 models were evaluated using the ASTM

Publikováno v: J Occup Environ Hyg

Recently, total inward leakage (TIL) for filtering facepiece and elastomeric half-mask respirators (EHRs) was measured according to the International Organization for Standardization (ISO) test method standard 16900–1:2014 that showed larger TIL fo

A comparison of facemask and respirator filtration test methods

Autor: Brandon Williams, Sarah Smit, Ronald E. Shaffer, Samy Rengasamy

Publikováno v: Journal of Occupational and Environmental Hygiene

NIOSH published a Federal Register Notice to explore the possibility of incorporating FDA required filtration tests for surgical masks (SMs) in the 42 CFR Part 84 respirator certification process. There have been no published studies comparing the fi

Assessment of respirator fit capability test criteria for full-facepiece air-purifying respirators

Autor: Samy Rengasamy, Susan Shuhong Xu, James R. Harris, Robert B. Lawrence, Michael S. Bergman, Brenda Boutin, Ziging Zhuang

An ASTM International subcommittee on Respiratory Protection, F23.65 is currently developing a consensus standard for assessing respirator fit capability (RFC) criteria of half-facepiece air-purifying particulate respirators. The objective of this st

Inward leakage variability between respirator fit test panels – Part II. Probabilistic approach

Autor: Yuewei Liu, Ziqing Zhuang, Christopher C. Coffey, Samy Rengasamy, George Niezgoda

Publikováno v: Journal of Occupational and Environmental Hygiene. 13:604-611

This study aimed to quantify the variability between different anthropometric panels in determining the inward leakage (IL) of N95 filtering facepiece respirators (FFRs) and elastomeric half-mask respirators (EHRs). We enrolled 144 experienced and no

Publikováno v: Journal of occupational and environmental hygiene. 15(8)

The International Organization for Standardization (ISO) standard 16900–1:2014 specifies the use of sodium chloride (NaCl) and corn oil aerosols, and sulfur hexafluoride gas for measuring total inward leakage (TIL). However, a comparison of TIL bet

Resistance to synthetic blood penetration of National Institute for Occupational Safety and Health-approved N95 filtering facepiece respirators and surgical N95 respirators

Autor: Ronald E. Shaffer, Samy Rengasamy, Deborah Sbarra, Julian Nwoko

Publikováno v: American Journal of Infection Control

Background Surgical N95 filtering facepiece respirators (FFRs), certified by the National Institute for Occupational Safety and Health (NIOSH) as a respirator and cleared by the Food and Drug Administration (FDA) as a surgical mask, are often used to
