Document cover

Project Scope


  • Measure filtration performance of filtering facepiece respirators against nanoparticles
  • Using manikin head form measure face seal leakage and filter performance of respirators against nanoparticles
  • Determine most penetrating particle size for surgical masks, dust masks, N95, P100, and FFP2 filters

Milestones

  • Q1 Submit two manuscripts to journals
  • Q2 Submit a review article on nanoparticle filtration of respirators for publication in the special issue of Journal of Nanoparticle Research
  • Q3 Submit manuscript on "Protection factor measurements using PortaCount" to journal
  • Q4 Submit manuscript on "Leakage of nanoparticles through filtering facepiece respirators" to journal

Outputs

  • Manuscripts published or submitted to peer review journals (approx. 4)
  • Presentations at conferences (approx. 19)
  • Standards committee meetings & public meetings (approx. 3)
  • NIOSH Best Practice Nanotech Guidance Documents

Outcomes

  • Experimental data from project is used in NIOSH, ASTM, & ISO guidelines for worker protection against aerosolized nanoparticles
  • DuPont uses NIOSH recommended test procedures for collecting data on barrier materials and filter media
