Objective
- 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.
|
- NFPA Protective Clothing Standards – 1991, 1994, 1971, 1951
- ASTM F739 Standard Test Method for Resistance of Protective Clothing Materials to Permeation by Liquids or Gases Under Conditions of Continuous Contact
- Emergency Responders
- Manufacturers
- Test Laboratories
- Certification Laboratories
 |
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
Milestones
- 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
|
Outputs
- 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
Outcomes
- Revisions or updates to NFPA 1994, NFPA 1971, NFPA 1991, NFPA 1951 and ASTM F739
- New ASTM cumulative permeation test method
