This project has resulted in two employee invention reports
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.
Improved standards and test methods for protective clothing used for protection against inert and biological aerosols.
