Development of Computer-Aided

Face-Fit Evaluation Methods - FY11

Objective

  • 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

  • ISO TC94 SC15 WG1 PG5
  • 29 CFR Part 1910.134

Key Partners

  • Texas Tech University
  • Canada National Research Council
  • ISEA

 

Stakeholders

  • OSHA
  • MSHA
  • ANSI
  • ISO
  • Respirator Users
  • 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 head forms

Milestones

  • Q1 Complete the report for NRC Canada contract
  • Q2 Submit a paper on headforms for Chinese workers to OD
  • Q3 Submit a paper on shape variations of US workers to OD
  • Q4 Complete shape analysis by Dennis Slice

Outputs

  • Manuscripts published or submitted to peer review journals (16)
  • Presentations at conferences (20)
  • Standards committee meetings & public meetings (10)

Outcomes

  • The techniques and methods developed in this study resulted 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
  • Outputs have been cited 48 times in the peer-reviewed literature
