Development of Computer-Aided Face-Fit Evaluation Methods - FY08


  • Establish up-to-date respirator fit-test panels and test headforms to be incorporated into the national and ISO standards
  • Develop an anthropometric database of Asian workers
  • Investigate the correlation between 3 -D parameters and face fit
Head form and fit test panel chart

Applicable Standards

  • 29 CFR Part 1910.134

Key Partners

  • Anthrotech
  • WVU
  • ISEA



  • OSHA
  • MSHA

  • ISO
  • Respirator Users and manufacturers
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 headforms


  • Q1 Draft a manuscript for the Chinese study
  • Q1 Draft a manuscript from Dennis Groce's study
  • Q1-Q2 Develop new sets of headforms
  • Q1-Q4 Draft a manuscript from Dennis' Slice study


  • Manuscripts published or submitted to peer review journals (approx. 8)
  • Presentations to stakeholders or conferences (approx. 10)
  • Standards committee meetings & public meetings (approx. 12)


  • 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 incorporated in respirator testing and certification
