Field Demonstration for Biological Agent Decon

We participated in a field test of the Sandia Decon Formulation at the U.S. Army Proving Grounds at Dugway, UT. This field test was designed to test the effectiveness of formulation in killing anthrax spores. The anthrax simulant, Bacillus globigii was sprayed onto various panels (2' x 2') of materials which would commonly be found in a typical office building. Since the area to be decontaminated was relatively small and to show the versatility of our formulation, the formulation was deployed onto the panels as a spray (using a standard paint sprayer) rather than as a foam. After 20 hours exposure to the formulation, Dugway personnel tested the panels for surviving spores. The tests were repeated on four consecutive days, and the results for the Sandia Decon Formulation are shown below.
