Individual and Collective Protection Program

Abstract

Abstract : The FY06-07 goal was to advance the development of the Triosyn Super HEPA (TSH) media as an enhanced filtration material to be included in individual protection and collective protection end-use applications. Work was also done to pursue the development of the Triosyn T-series respirators. The objectives were achieved and resulted in a mature Triosyn Super HEPA filter material. A manufacturing process to incorporate Triosyn particles to glass fiber HEPA was developed to produce a material which maintains standard HEPA performance but also displays enhanced antimicrobial and chemical protection properties due to the presence of Triosyn. The antimicrobial performance of this media was demonstrated under a variety of testing conditions and following exposure to different microbial challenges. The Triosynated material's safety profile was also well-defined as measured by the iodine levels released in the effluent air under several exposure conditions. The chemical protection capability of the TSH was demonstrated following exposure of the media to surrogates of chemical warfare agents and potential incompatibilities originating from adverse interactions between iodine and the ASZM-TEDA carbon were investigated. This advanced TSH filter material is now ready for the next research steps which involve prototype designing for insertion into various individual and collective protection applications.
