Size-Resolved Penetration of Filtering Materials from CE-Marked Filtering Facepiece Respirators
Throughout the years, the performance of the FFRs has been the topic of extensive studies, resulting mainly in the characterization of aerosol penetration through filters using aerosols that are thought to be similar to those encountered in workplaces. There are limited number of studies in the literature reporting CE-marked respirator performance, and there is a need to perform a penetration e...
متن کاملComparison of nanoparticle filtration performance of NIOSH-approved and CE-marked particulate filtering facepiece respirators.
The National Institute for Occupational Safety and Health (NIOSH) and European Norms (ENs) employ different test protocols for evaluation of air-purifying particulate respirators commonly referred to as filtering facepiece respirators (FFR). The relative performance of the NIOSH-approved and EN-certified 'Conformité Européen' (CE)-marked FFR is not well studied. NIOSH requires a minimum of 95 a...
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 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 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...
