Evaluation of N95 Filtering Facepiece Respirators Challenged with Engineered Nanoparticles
NIOSH-certified respirators, including N95 respirators, are recommended when engineering and administrative controls do not adequately prevent exposures to airborne nanomaterials. Laboratory evaluations of filtering efficiency using standard test aerosols have been reported in the literature, but there is no information on penetration of engineered nanoparticles (1–100 nm) for N95 filtering fac...
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 کاملProtection factor for N95 filtering facepiece respirators exposed to laboratory aerosols containing different concentrations of nanoparticles.
A previous study used a PortaCount Plus to measure the ratio of particle concentrations outside (C out) to inside (C in) of filtering facepiece respirators (FFRs) worn by test subjects and calculated the total inward leakage (TIL) (C in/C out) to evaluate the reproducibility of the TIL test method between two different National Institute for Occupational Safety and Health laboratories (Laborato...
متن کاملFilter Performance Degradation of Electrostatic N95 and P100 Filtering Facepiece Respirators by Dioctyl Phthalate Aerosol Loading
Polydisperse dioctyl phthalate (DOP) aerosols are employed for testing filter penetration with loading of Rand P-series particulate filters for National Institute for Occupational Safety and Health (NIOSH) certification. Penetration for filters must not exceed NIOSH allowed maximum levels during the entire loading of 200 mg DOP indicating no filter degradation. Degradation of respirators loaded...
متن کاملRespiratory protection provided by N95 filtering facepiece respirators against airborne dust and microorganisms in agricultural farms.
A new system was used to determine the workplace protection factors (WPF) for dust and bioaerosols in agricultural environments. The field study was performed with a subject wearing an N95 filtering facepiece respirator while performing animal feeding, grain harvesting and unloading, and routine investigation of facilities. As expected, the geometric means (GM) of the WPFs increased with increa...
