Patent number: 7276468Abstract: A decontamination formulation and method of making that neutralizes the adverse health effects of both chemical and biological compounds, especially chemical warfare (CW) and biological warfare (BW) agents, and toxic industrial chemicals. The formulation provides solubilizing compounds that serve to effectively render the chemical and biological compounds, particularly CW and BW compounds, susceptible to attack, and at least one reactive compound that serves to attack (and detoxify or kill) the compound. The formulation includes at least one solubilizing agent, a reactive compound, a sorbent additive, and water. A highly adsorbent sorbent additive (e.g., amorphous silica, sorbitol, mannitol, etc.) is used to “dry out” one or more liquid ingredients into a dry, free-flowing powder that has an extended shelf life, and is more convenient to handle and mix in the field.Type: GrantFiled: December 18, 2003Date of Patent: October 2, 2007Assignee: Sandia CorporationInventor: Mark D.

Patent number: 7271137Abstract: Aqueous decontamination formulations that neutralize biological pathogens for disinfection and sterilization applications. Examples of suitable applications include disinfection of food processing equipment, disinfection of areas containing livestock, mold remediation, sterilization of medical instruments and direct disinfection of food surfaces, such as beef carcasses. The formulations include at least one reactive compound, bleaching activator, inorganic base, and water. The formulations can be packaged as a two-part kit system, and can have a pH value in the range of 7-8.Type: GrantFiled: January 27, 2004Date of Patent: September 18, 2007Assignee: Sandia CorporationInventors: Mark D. Tucker, Daniel E. Engler

Patent number: 7186877Abstract: Methods and systems for processing vesicants as well as other irritants are described. In some methods a vesicant, for example, a Lewisite such as the L1 form, the L2 form, L3 form, or combination thereof, is combined with permanganate, for example, as an aqueous solution of sodium permanganate. The methods can include releasing the vesicants or irritants from a munition, for example, by explosively rupturing the munition.Type: GrantFiled: September 27, 2005Date of Patent: March 6, 2007Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Kevin M. Morrissey, H. Dupont Durst, Lucille P. Forrest, Mary P. Weiss

Patent number: 7097858Abstract: Polyoxometalate topical compositions for removing contaminants from an environment and methods of use thereof are disclosed. An embodiment of the polyoxometalate topical composition includes a topical carrier and at least one polyoxometalate, with the proviso that the polyoxometalate is not H5PV2Mo10O40; K5Si(H2O)MnIIIW11O39; K4Si(H2O)MnIVW11O39; or K5CoIIIW12O40. Another embodiment relates to a method for removing a contaminant from an environment, including contacting the polyoxometalate topical composition with the environment containing the contaminant for a sufficient time to remove the contaminant from the environment.Type: GrantFiled: April 29, 2002Date of Patent: August 29, 2006Assignee: Emory UniversityInventors: Craig L. Hill, Ling Xu, Jeffrey T. Rhule, Eric A. Boring

Patent number: 7087805Abstract: A method and apparatus for neutralizing biological and/or chemical warfare agents using an ozone-containing solution. The ozone-containing solution is produced by combining ozone-containing gas with an ozone vehicle, such as an organic solution. The ozone-vehicle prolongs the shelf life of the ozone to allow for extended periods of storage. A storage container is used to store the ozone-containing solution and facilitate its transportation to an environment contaminated by the biological and/or chemical warfare agents, or near a potential site for biological or chemical attack. The ozone-containing solution is drawn out of the storage container to apply it to a contaminated environment.Type: GrantFiled: October 22, 2002Date of Patent: August 8, 2006Assignee: STERIS Inc.Inventors: Michael A. Centanni, Daniel J. Subach, Iain F. McVey

Patent number: 7064241Abstract: A microemulsion composition having a solid source of peroxycarboxylic acid and germinant is used for chemical and biological warfare decontamination. A process for decontaminating uses the microemulsion composition.Type: GrantFiled: September 16, 2003Date of Patent: June 20, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Jerry S. Brown, Richard C. Hodge, Margaret A. McCabe, Karen A. McGrady, Amanda S. Schilling

Patent number: H2198Abstract: A method of decontaminating solids contaminated with chlorinated hydrocarbons includes a first step of heating the contaminated solids at a temperature high enough to volatize chlorine contaminates but below a temperature range favorable to the formation of the dioxins and furans to dechlorinate the contaminated solids. Volatilized chlorine contaminates are removed from the dechlorinated contaminated solids. The dechlorinated contaminated solids are then purged with an inert gas to remove oxygen from the dechlorinated contaminated solids. Thereafter the dechlorinated contaminated solids are heated in the absence of oxygen to a temperature sufficient to crack hydrocarbons contaminating the solids to lower molecular weight hydrocarbons.Type: GrantFiled: July 30, 2002Date of Patent: August 7, 2007Assignee: CH2M Hill Inc.Inventor: Jay M.
