A Feasibility study of quantitative respirator fit testing by controlled negative pressure / Clifton D. Crutchfield, Martin P. Eroh, Mark D. Van Ert
Sumario: The feasibility of using a direct measure of respirator leakage flow rate as a quantitative index of respirator face seal fit has been explored through the use of a new controlled negative pressure method. The method is based on exhausting air from a temporarily sealed respirator facepiece at a rate sufficient to generate and then sustain a constant negative pressure inside the facepiece while the wearer holds his breath
