Figure 2.
Los Alamos National Laboratory (LANL) and National Institute for Occupational Safety and Health (NIOSH) full-face-piece panels based on face length and face width are shown. The dotted lines define LANL panel boundaries and the solid lines outline the NIOSH 2007 panel borders. The cells are numbered 1 to 10, and the numbers in parentheses indicate the number of models/participants to be sampled from each cell. When the participant’s face length or face width fall on cell boundaries, the participant is placed in the higher number cells with larger face dimensions.
