  • Publication number: 20170112156
    Abstract: A method for decontaminating articles having porous outer surfaces. The method includes steps of: providing a decontamination chamber; conveying the articles through the decontamination chamber at a predetermined speed wherein the speed is selected such that the articles are disposed in the decontamination chamber for a predetermined period of time; providing a source of sterilant vapor, the source providing the sterilant vapor at a temperature within a predetermined acceptable temperature range and at a concentration within a predetermined acceptable concentration range; conveying a sterilant vapor from the source of sterilant vapor to the decontamination chamber; and exposing the articles to the sterilant vapor. The predetermined period of time and the predetermined acceptable concentration range of the sterilant vapor are selected such that the sterilant vapor does not penetrate the porous outer surfaces of the articles.

  • Publication number: 20150373986
    Abstract: This invention relates to an aqueous composition and a process for killing spores. The process may comprise contacting the spores with the aqueous composition for a sufficient period of time to effect a desired reduction (e.g., at least a 4 log reduction) in the number of spores capable of returning to vegetative growth. The aqueous composition may comprise water, an antimicrobial agent (e.g., peracetic acid) and a peroxide (e.g., hydrogen peroxide). The process may be a two-step process involving the use of a first aqueous composition, which may comprise water and the peroxide, and a second aqueous composition which may comprise water and the antimicrobial agent.
