Effect of upper strap downward displacement on n95 filtering facepiece respirator fit factors: a pilot study.
Fifteen subjects underwent three replicates of quantitative respirator fit-testing with N95 filtering facepiece respirators that were donned with the upper strap high on the occiput, as per the manufacturers' donning instructions. Each fit-test was immediately followed by repeat fit-testing with the upper strap downwardly displaced to the level of the ear sulcus to determine any change in fit f...
متن کاملSurvival 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 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 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 کاملCharacterization of small-to-medium head-and-face dimensions for developing respirator fit test panels and evaluating fit of filtering facepiece respirators with different faceseal design
A respirator fit test panel (RFTP) with facial size distribution representative of intended users is essential to the evaluation of respirator fit for new models of respirators. In this study an anthropometric survey was conducted among youths representing respirator users in mid-Taiwan to characterize head-and-face dimensions key to RFTPs for application to small-to-medium facial features. The...
