Publication Cover Assessment of the NIOSH Head and Face Anthropometric Survey of U S Respirator Users and 3 D Head form

Project Scope

  • Develop an anthropometric survey detailing the face size distributions of respirator users using both traditional measurement methods and three-dimensional (3-D) scanning systems
  • Investigate the extent to which facial features can predict respirator fit and protection
  • Develop respirator fit test panels using the traditional bivariate approach and the principal component analysis (PCA)
  • Develop test head forms


  • Q1 Complete the third generation head form development.
  • Q2 Submit manuscript for the new head forms to OD for approval.
  • Q3 Submit the manuscript on facial differences between gender, age, and race to OD for approval.
  • Q4 Draft an abstract for AIHce 2010 and Complete investigation of the association between fit and 3-D shape parameters.


  • Manuscripts published or submitted to peer review journals (approx. 9)
  • Presentations at conferences (approx. 19)
  • Standards committee meetings & public meetings (approx. 10)


  • The techniques and methods developed in this study will result in the ability of manufacturers to design respirators with improved face-fitting characteristics
  • Fit Test Panel and head forms incorporated in respirator testing and certification and ISO standards
