Material Demand Studies: Materials Sorption of Vaporized Hydrogen Peroxide

摘要

To address Homeland Security's needs for decontamination, the EPA established an Interagency Agreement with the U.S. Army Edgewood Chemical Biological Center (ECBC) to take advantage of ECBC's extensive expertise and specialized research facilities for the decontamination of surfaces contaminated with chemical and biological (CB) warfare agents. The National Homeland Security Research Center (NHSRC) collaborated with ECBC, in a mutual leveraging of resources, to expand upon ECBC's on-going programs in CB decontamination. The goal was to more completely address the parameters of particular concern for decontamination of indoor surfaces in buildings following a terrorist attack using CB agents, toxic industrial chemicals (TICs), or materials (TIMs). Vaporized hydrogen peroxide (VHP(Registered)) and chlorine dioxide (CIO2) are technologies that have been used to decontaminate indoor surfaces contaminated with anthrax. The technologies also show potential for use in decontaminating indoor surfaces contaminated by chemical agents. This program is specifically focused on decontamination of the building environment to restore a public building to a usable state after a terrorist contamination episode. Because building interiors may contain a large surface composed of concrete cinder block, wood, steel, carpet, ceiling suspension tile, and painted wallboard. the effort was designed to determine how building materials impact the concentration/titer of decontaminant in the vapor phase. The focus of this technical report is the evaluation of the building interior materials and the Steris VHP technology.
