Fitting Characteristics of N95 Filtering-Facepiece Respirators Used Widely in China
BACKGROUND Millions of people rely on N95 filtering facepiece respirators to reduce the risk of airborne particles and prevent them from respiratory infections. However, there are no respirator fit testing and training regulations in China. Meanwhile, no study has been conducted to investigate the fit of various respirators. The objective of this study was to investigate whether people obtained...
متن کاملEvaluation of particle penetration and breathing resistance of N95 filtering face-piece respirators and uncertified dust masks
Evaluation of particle penetration and breathing resistance of N95 filtering face-piece respirators and uncertified dust masks. has been approved by the Examining Committee for the thesis requirement for the Doctor of Philosophy degree in Occupational and Environmental Health (Industrial Hygiene) at the December 2015 graduation. ii To family and friends, thank you for your support iii ACKNOWLED...
متن کاملEvaluation of five decontamination methods for filtering facepiece respirators.
Concerns have been raised regarding the availability of National Institute for Occupational Safety and Health (NIOSH)-certified N95 filtering facepiece respirators (FFRs) during an influenza pandemic. One possible strategy to mitigate a respirator shortage is to reuse FFRs following a biological decontamination process to render infectious material on the FFR inactive. However, little data exis...
متن کاملTotal inward leakage of nanoparticles through filtering facepiece respirators.
Nanoparticle (<100 nm size) exposure in workplaces is a major concern because of the potential impact on human health. National Institute for Occupational Safety and Health (NIOSH)-approved particulate respirators are recommended for protection against nanoparticles based on their filtration efficiency at sealed conditions. Concerns have been raised on the lack of information for face seal leak...
متن کاملEvaluation 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...
