Risk Based Protective Clothing Material Permeation Criteria FY12

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.


  • Examine existing toxicity data for selected toxic industrial chemicals (TICs) to determine ratios of acceptable dermal to inhalation doses and create detailed permeation procedures in parallel to apply criteria.

Project Scope

  • Develop uniform cumulative permeation testing parameters and procedures to increase ease and reproducibility
  • Provide data on the effect of temperature and humidity control and testing
  • Investigate different existing and experimental permeation cells to understand the optimization for different test applications


  • Q1 - Complete flow rate experiments using acrylonitrile and dimethylsulfate
  • Q2 - Present preliminary findings at ASTM F23.30 meeting
  • Q3 - Submit manuscript (Critical analysis of the AVLAG Permeation Cell for use in NFPA 1994: Standard on Protective Ensembles for First Responders to CBRN Terrorism Incidents) to peer-reviewed journal
  • Q4 End of project. Ongoing work will be conducted under the new start project on chemical permeation


  • Presentations at conferences (9)
  • Presentation at standards committee and public meetings (2)
  • Manuscripts published or submitted to peer review journals (1 in progress)
  • TSWG final report with technical data including recommended criteria/end points and methods for permeation testing for use by the NFPA Technical Committees and ASTM F23


  • Revisions or updates to NFPA 1994, NFPA 1971, NFPA 1991, NFPA 1951 and ASTM F739
  • New ASTM cumulative permeation test method
