Selection of respirator test panels representative of U.S. adult facial sizes
As requested by the National Institute for Occupational Safety and Health (NIOSH), the Los Alamos Scientific Laboratory Respirator Research and Development Section, Industrial Hygiene Group, has prepared anthropometric specifications for subjects to test the fit of half-mask, quarter-mask, and full- facepiece respirators. A facial survey of 200 males was conducted, with results similar to those of a recent survey of some 4000 U. S. airmen. Subjects were selected on the basis of face length and face width to wear full-face masks in tests. For testing halfand quarter-masks, face length and lip length were used. Test panels containing 25 male-and-female subjects were used to represent a majority of the working population. A sequential sampling scheme was developed to reduce the amount of testing required to determine if a mask provides adequate protection for diffurent facial sizes. Examples of man test results are given. (auth)
