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

DF-200 FormulationCharacteristics
• 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

The foam can be deployed through a variety of delivery
systems - both large-scale and small-scale
• 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 RegistrationDF-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
Sandia Decon Formulation (DF-200)Military Use
The US Military has recently purchased relatively large
quantities of DF-200 for possible use in the War
Against Terrorism
