Correlation of respirator fit measured on human subjects and a static advanced headform.
This study assessed the correlation of N95 filtering facepiece respirator (FFR) fit between a Static Advanced Headform (StAH) and 10 human test subjects. Quantitative fit evaluations were performed on test subjects who made three visits to the laboratory. On each visit, one fit evaluation was performed on eight different FFRs of various model/size variations. Additionally, subject breathing pat...
متن کاملRespirator fit-testing - will we pass the test?
The UK Health Protection Agency advises health care workers caring for patients with probable or confirmed flu-like illnesses, with serious respiratory illnesses or where aerosol generating procedures are being undertaken to use a filtering face piece-3 (FFP3) respirator [1]. Whereas masks protect the environment from wearers, respirators by design protect wearers from the environment. Some sur...
متن کاملEvaluation of half-face respirator fit in an Iranian petrochemical company's workers
Introduction: The performance of respirator-face piece is depending on a good contact between the worker's face and the respirator. Improper sealing can cause reduction in performance of respirators to protect health and safety of workers against risks related to chemical agents at work. This study is aimed to evaluate the fitness of half-face respirators and other related factors on it in an...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولHeadform 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...
