Decontamination
Performance for Biological Agent Simulants
At Sandia
National Laboratories (SNL) we tested the decontamination
performance of the Sandia Decon Formulation for biological
agent simulants. The biological agent simulants used were
Bacillus globigii (a simulant for anthrax spores),
Erwinia herbicola (a simulant for vegetative bacterial
cells), and MS-2 bacteriophage (simulant for viruses).
For the B. globigii spores, a 7-log kill was achieved
in an hour. Likewise, similar results for the vegetative bacterial
cells and the viruses were achieved in 15 and 30 minutes respectively.
We confirmed
our biological agent simulant test results by contracting
with a facility licensed to perform live agent testing of
anthrax. A solution test was performed (i.e., the spores were
added to our decontamination solution). As evident in the
figure below, a 7-log kill was achieved during a one hour
exposure period.
