Nanoparticle Penetration Through Protective Clothing FY09

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

Objective

  • To investigate nanoparticle penetration through protective clothing materials due to pressure differences across the fabric.

Applicable Standards

  • ASTM F23
  • NFPA 1994, 1971, 1951

Key Partners

  • NIOSH NTRC
  • International Personnel Protection, Inc
  • DuPont Personal Protection

 

Stakeholders

  • NIOSH NTRC
  • PPE manufacturers
  • ASTM
  • NFPA
  • IAFF
  • DuPont NOSH consortium

Project Scope


  • Develop a predictive model
  • Select test fabrics and determine physical properties
  • Conduct laboratory experiments
  • Conduct data analysis and model comparison

Milestones

  • Q1 Complete model improvement (Task D1) and Complete selection of test fabrics (Task D2.1)
  • Q2 Complete characterizing relation between wind velocity and face velocity (Task D3.1.1)
  • Q3 Complete measuring particle penetration through fabrics using a modified TSI 3160, including 18 different particle sizes from 10 nm to 500 nm at 6 different face velocities (Tasks D3.1.2 & D3.2)
  • Q4 Complete two draft manuscripts (Task D5)

Outputs

  • Final report, published papers
  • National/International conference(s) presentation

Outcomes

  • The predictive models can be used by government agencies, standards development organizations, and professional organizations to improve and/or develop scientifically appropriate guidance documents, protective clothing performance requirements, and test methods
  • Particle penetration data from this study can be used to improve NIOSH guidance on the penetration of nanoparticles through protective clothing and ensembles
