Survival of Bacteriophage MS2 on Filtering Facepiece Respirator Coupons
The reuse of filtering facepiece respirators (FFRs) after decontamination has been suggested as a strategy to conserve supplies during an influenza pandemic. The feasibility of decontaminating FFRs has been investigated under laboratory conditions; however, the need for decontamination of FFRs is not well characterized. In this study the potential for FFRs to act as fomites was examined using b...
متن کاملEvaluation of Full-Facepiece Respirator Fit on Fire Fighters in the Municipality of Jeddah, Saudi Arabia
The purpose of this study was to assess the effect of personal variables on the fit of the respirators used by firefighters and workers in highly polluted environments. However, resistance from many plants managers was met to conduct the study on their workers. Therefore, we were forced to limit the study on firefighters who were found very cooperative. Forty volunteer firefighters from differe...
متن کاملMeasurement of mass-based carbon nanotube penetration through filtering facepiece respirator filtering media.
Recent studies suggest that a wide range of human health effects could result from exposure to carbon nanotubes (CNTs). A National Institute for Occupational Safety and Health survey of the carbonaceous nanomaterial industry found that 77% of the companies used respiratory protection, such as filtering facepiece respirators (FFRs). Despite CNT studies in some occupational settings being reporte...
متن کاملHeadform and N95 filtering facepiece respirator interaction: contact pressure simulation and validation.
This article presents a computational and experimental study of contact pressure between six N95 filtering facepiece respirators (FFRs) and five newly developed digital headforms (small, medium, large, long/narrow, and short/wide). Contact interaction is simulated using the finite element method and validated by experiments using a pressure mapping system. The headform model has multiple layers...
متن کاملPhysiological impact of the N95 filtering facepiece respirator on healthcare workers.
OBJECTIVE To assess the physiological impact of the N95 filtering facepiece respirator (FFR) on healthcare workers. METHODS Ten healthcare workers each conducted multiple 1-hour treadmill walking sessions, at 1.7 miles/h, and at 2.5 miles/h, while wearing FFR with exhalation valve, FFR without exhalation valve, and without FFR (control session). We monitored heart rate, respiratory rate, tida...
