Project Scope


  • Task 1. Optimization of the magnetic passive aerosol sampler (PAS) design - evaluating PAS efficiency under various conditions and interferences, numerical simulation, and comparison with reference samplers.
  • Task 2. Development and validation of a standardized bench-scale particulate penetration test method.

Milestones

  • Q1 Built a new aerosol chamber that is able to create wind speeds up to 10 miles/hr for evaluating particle penetration through clothing materials using magnetic aerosol samplers
  • Q2 Evaluate the performance of the aerosol chamber
  • Q3 Complete testing effect on particle size, aerosol concentration, and wind speed for the passive sampler
  • Q4 Complete testing effect on particle size, aerosol concentration, and wind speed for the passive sampler

Outputs

  • Manuscripts published or submitted to peer review journals (approx. 1)
  • Presentations to stakeholders or conferences (approx. 7)
  • This project has resulted in two employee invention reports

Outcomes

  • This project has contributed to the PPE section in Chapter 4 of the NIOSH Nanotechnology Research Center (NTRC) document titled "Progress toward Safe Nanotechnology in the Workplace" and the NTRC report titled "Approaches to Safe Nanotechnology: An Information Exchange with NIOSH" Feb. 2007.
  • This project has resulted in a new research proposal entitled "Nanoparticle penetration through protective clothing", which has been selected and funded by NIOSH NTRC for a new FY09 project. Feb. 2007.
  • Expected end outcome is reduced occupational dermal exposure to aerosol, bioaerosols, and nanoparticles through improved standards and test methods for protective clothing
