Document cover of Approaches to safe nanotechnology

Project Scope

  • Using flat plate system measure 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 N95, P100, and FFP2 filters


  • In-house nanoparticle generation and test systems will be set up
  • Research proposal on nanoparticle penetration will be submitted for external peer review
  • Begin experimental studies per approved protocol


  • Manuscripts published or submitted to peer review journals (approx. 1)
  • Presentations to stakeholders or conferences (approx.1)
  • Standards committee meetings & public meetings (approx.1)
  • NIOSH Best Practice Nanotech Guidance Documents


  • 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
