Response to a Domestic CBW Incident Event Timeline CBW Event First Response Facility Restoration Re-Occupy Facility Detection Decontamination / Restoration Fate and Transport Modeling Risk Assessment Mitigation

The Objective To develop a rapid, effective, and safe decontamination technology for the restoration of civilian facilities in the event of a domestic terrorist attack The Challenges Rapid Deployment Rapid Destruction of CBW Agents Common Formulation for all CBW Agents Low toxicity and corrosivity Sandia Decon Foam Development Overview The Problem Historical decon formulations for CBW agents are highly toxic and/or highly corrosive Our Response Sandia has developed an aqueous formulation with low toxicity and corrosivity properties for the rapid destruction of CBW agents

Corrosion Comparisons Bleach - 24 Hour Exposure Sandia Decon Foam - 24 Hour Exposure Deionized Water - 24 Hour Exposure Steel Coupons

DF-200 Formulation Characteristics Rapid response –quick to deploy –quick to react Low logistics support and water demand and minimal run-off of fluids Minimal health and collateral damage –low toxicity and corrosivity properties Applicable in a variety of scenarios –work has mostly focused on deployment as a foam –formulation can also be deployed as a spray, fog, mist, or cream Successful results in a number of laboratory and field tests –RestOps, JSFDS, Dugway Spore Kill Tests Successfully used in actual remediation of anthrax contaminated buildings

As a result of the October 2001 anthrax incidents, the EPA is now clearly identified as the lead agency for remediation The EPA has determined that all products used for anthrax remediation must be registered as sterilants EPA Registration DF-200 Status Sterilant registration requires completion of AOAC sporicidal tests against Bacillus and Clostridium spores on two different carriers (porcelain cylinder and suture loop) Both Envirofoam Technologies and Modec have submitted their products to EPA-approved laboratories for testing One company has passed the sporicidal tests while the other company’s tests are still in progress
