Patent ID: 7153471

Claim:
A method of decontaminating a building interior contaminated by Bacillus anthraces comprising the steps of: (a) substantially sealing a contaminated building interior sufficiently to enable retention of a predetermined concentration of methyl bromide gas; (b) introducing methyl bromide gas into the substantially sealed contaminated building interior to a concentration of methyl bromide in an amount sufficient to deactivate said Bacillus anthraces and disable germination of Bacillus anthraces spores; (c) maintaining said substantially sealed contaminated building interior with said concentration of methyl bromide for a sufficient period of time to deactivate said Bacillus anthraces and to disable germination of said Bacillus anthraces spores associated with said contaminated building interior; (d) wherein the concentration of methyl bromide gas and period of time are inversely varied while providing a sufficient gas concentration to disable germination of said Bacillus anthraces spores associated with said contaminated building interior; and (e) wherein a baseline concentration of methyl bromide gas is approximately 80 mg/liter, and a baseline period of time is 48 hours.
