Using 3D Head and Respirator Shapes to Analyze Respirator Fit

摘要

A computational approach to analyzing respirator 111 is demonstrated using geometries generated by laser scanning, mechanical drawings, and CAD files. Three fit-related problems that can be solved using computational tools are demonstrated: I) The study of an outward leak of breathing gases into a near-flammable environment. 2) The study of a How field inside a half-facepiece respirator. 3) The characterization of the relationship of respirator design and head shape to fit and comfort.
