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
- NFPA
- TSWG (Funded in part by TSWG)
- ASTM International
- Emergency Responders
- Manufacturers
- Test Laboratories

Project Scope
- Determine new permeation test end points for TICs that are toxicity-based.
- Develop uniform permeation testing parameters and procedures to increase ease and reproducibility.
- Provide new permeation criteria and test methods to standards to lessen over design of barrier protective clothing.
Milestones
- Collection of dermal/inhalation toxicity data for selected TICs Collection of dermal/inhalation toxicity data for selected TICs.
- Evaluation of skin permeation models.
- Analysis of dermal and respiratory toxicity data and development of model for predicting acceptable doses..
|
Outputs
- Manuscripts published or submitted to peer review journals (approx. 1)
- Presentations to stakeholders or conferences (approx. 3)
- Standards committee meetings & public meetings (approx.8)
- 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.
- Model that predicts acceptable doses for selected TICs which could be expanded to additional TICs.
Outcomes
- Revisions or updates to NFPA 1994, NFPA 1971, NFPA 1991, NFPA 1951 and ASTM F739.
