Definitions
- the present invention relates to methods and compositions for decontaminating exposed surfaces or spaces which may be contaminated with chemical and biological warfare agents and the like.
- the invention is also applicable to treat industrial pollution, or may be used to decontaminate organic pollutants such as occur in contaminated soils and sludges, for biodegradability improvement, odour and colour removal, pesticide destruction, removal of other OH&S toxins and the like.
- Warfare Agents include nerve agents (such as tabun, sarin, soman, cyclosarin, VE, VG, VM, VX and Novichok agents), blood agents (such as arsine), blistering agents (such as sulfur mustards, nitrogen mustards, lewisites, ethyldichloroarsine, methyldichloroarsine and phenyldichloroarsine), pulmonary or choking agents (such as adamsite, acrolein, bis(chloromethyl)ether, chlorine, chloropicrin, diphosgene, methylchlorosulfonate, phosgene and stannic chloride), lachrymators (such as, pepper spray, alpha chlorotoluene, benzyl bromide, bromoacetone, bromobenzylcyanide, bromomethyl ethyl ketone, capsaicin, chloracetophenone,chloromethyl chloroformate, dibenz
- Biological Warfare Agents include anthrax, ebola, Marburg virus, plague, cholera, tularemia, brucellosis, Q fever, machupo, coccidioides mycosis, glanders, melioidosis, shigella, Rocky Mountain spotted fever, typhus, psittacosis, yellow fever, Japanese B encephalitis, Rift Valley fever, and smallpox.
- these agents are applied indiscriminately to spaces where they contaminate the air or contaminate surfaces.
- These agents are biologically effective because they are chemically reactive or interactive with the human body.
- Liquid oxidants, especially hydrogen peroxide, and hypochlorite solutions have been found to be generally efficacious in deactivating a large range of biological and chemical warfare agents.
- liquid agents cannot practically decontaminate these agents when dispersed in the air, and nor can they be used reliably to penetrate between mated surfaces.
- the use of large quantities of liquid decontaminant can itself be destructive of the environment and materials within the environment. Most oxidants are harmful to the skin and corrosive to equipment and removal of the decontaminant is itself problematic.
- a number of chemically active warfare agents are known. Although banned by most countries, such agents are open to use by terrorists and the like against defenseless populations, or by less scrupulous states in more conventional combat settings.
- agents include ACE inhibitors, blistering agents and biotoxins
- these agents can be removed to some extent by traditional scrubdown techniques, however, these are very labour intensive, often hazardous for the scrubbers and not always effective against water insoluble compounds or particulates which are slowly or partially soluble.
- the labour costs for extensive scrubdowns are also very high. Simple washing or removal with solvents may also be possible, but large quantities of contaminated solvent are produced, and the general problems with using liquid rinsing remain (drying, inability to reach mated or occluded surfaces etc).
- the most effective methods for decontaminating such chemical agents have involved treating contaminated items with bleach (aqueous calcium or sodium hypochlorite) or aqueous sodium hydroxide solution containing diethylenetriamine.
- the invention provides a method for decontaminating or partially decontaminating a surface or space contaminated with a contaminant selected from the group consisting of chemical warfare agents, industrial pollutants, pesticides, toxins and the like said method comprising the step of contacting the contaminated surface or space with an aerosol comprising a decontaminating agent and subsequently or simultaneously contacting the decontaminated surface or space with an aerosol comprising a decontaminating agent antagonist.
- the decontaminating agent is an oxidizing agent or combination of oxidizing agents and more preferably comprises a peroxide.
- antagonist any substance which reacts with, neutralizes, catalyses the destruction or otherwise changes another substance - in this case the decontaminating agent or acts as an intermediary in its destruction or inactivation.
- the invention provides a method according to the first aspect comprising the step of contacting the contaminated surface or space with an aerosol comprising droplets dispersed in a carrier gas, wherein at least some of the droplets contain a decontaminating agent effective to render the contaminant harmless or reducing its ability to cause harm, and at least some of the droplets contain an antagonist effective to render the decontaminating agent harmless or reducing its ability to cause harm.
- the invention provides a method according to the second aspect wherein at least some of the droplets contain BOTH a decontaminating agent effective to render the contaminant harmless or reducing its ability to cause harm, and an antagonist effective to render the decontaminating agent harmless or reducing its ability to cause harm.
- the invention provides an aerosol comprising droplets dispersed in a carrier gas, wherein at least some of the droplets contain a decontaminating agent effective to decontaminate a surface or space contaminated with a contaminant selected from the group consisting of chemical warfare agents, industrial pollutants, pesticides, toxins and the like whereby to render the contaminant harmless or reducing its ability to cause harm and at least some of the droplets contain an antagonist effective to render the decontaminating agent harmless or reducing its ability to cause harm.
- the invention provides an aerosol according to the fourth aspect wherein at least some of the droplets contain both the decontaminating agent and the antagonist reactive with the biocide to render it harmless or reducing its ability to cause harm
- the invention provides a self inactivating aerosol according to the third or fourth aspect wherein the nature and concentration of the antagonist is selected, or means are provided, to ensure that the time required for the antagonist to render the biocide ineffective is longer than the time required for the decontamination agent to be effective to render the contaminant harmless or reducing its ability to cause harm.
- the decontaminating agent is selected having regard to the chemistry of the contaminant according to principles which are known to those skilled in the art.
- the decontaminating agent is hydrogen peroxide by virtue of its broad applicability and the decontaminating agent antagonist is any suitable catalytic destructor (for example manganese or other transition metals, metal ions, metal oxides, or salts, or combinations of the foregoing; amines such as triethanolamine and diethylenetriamine; enzymes such as catalases; or the like).
- Another means of reducing the potency of many contaminants which are in the form of very fine particles is to flocculate them so the nebulising of a flocculant could significantly reduce the ability of the contaminant to cause harm.
- peroxides other than hydrogen peroxide may be employed as the decontaminating agent without departing from this invention for example £-butyl hydroperoxide or urea hydrogen peroxide.
- the invention is applicable to decontaminating agents other than peroxides for example other oxidizing agents such as ozone, permanganate, perchromate, oxy halides, peracetic acid, performic acid, perborates, ethylene oxide, chlorine dioxide, hypochlorites and combinations of oxidizing agents (optionally activated by "bleach activators" such as for example acetyl choline chloride, monoacetin, diacetin,).
- non oxidizing decontaminating agents such as quats, silananol, glycols, halogenated phenols, and the like may be employed by suitable selection of antagonists.
- antagonists other than those exemplified may be employed including all those known for use in catalytic destructors for peroxides and including (but not limited to) other metal catalysts such as iron, copper, cobalt, vanadium, nickel, chromium, manganese, osmium and silver, titanium, metals of the platinum group, metal ions, inorganic oxides and anhydrides, or salts, or combinations of the foregoing; amines such as triethanolamine, and other suitable bases, suitable oxy halide compounds MOX (wherein M is an alkali metal, O is oxygen, X is a halogen - for example, NaOCl); sulfides, amines, alcohols and other compounds known to react with peroxides
- Suitable antagonists may be formed in situ by reaction in the droplets from precursors and the kinetics of the formation reaction may be used to increase the induction time or affect the kinetics of reaction between decontaminating agent and antagonist.
- the antagonist need not be in liquid form but may be a suspension of microfine solid either formed in situ or nebulised as a suspension in a liquid carrier.
- a solution of NaOCl may be used as an aerosol decontaminating agent nebulised in a first nebuliser and hydrogen peroxide may then be used as an antagonist nebulant generated from a second nebuliser.
- the droplets combine and the following reaction occurs:
- Combinations of peroxide, peracetic acid and NaOCl have been found to be particularly effective as decontaminating agents and to form harmless residues on inactivation.
- Suitable antagonists can be selected from among oxidizing agents and reducing agents for other decontaminating agents.
- Fenton's reaction (and analogues thereof) can also be employed in the present invention.
- an iron catalyst as a solution of FeSO 4 may be combined with the hydrogen peroxide (typically
- hydroxyl radicals can then be utilized as an antagonist via addition reactions as exemplified by reaction with benzene:
- the decontamination agent may be combined with bleach activators.
- the antagonist When the antagonist is in an aerosol separate from the decontamination agent it may be introduced after a time delay sufficient to ensure that the decontamination agent was effective in destroying the contaminant.
- both decontamination agent and antagonist are combined in a single aerosol and the kinetics of the reaction between the decontamination agent with the contaminant and the agonist with the decontamination agent are chosen so that decontamination is carried out before the decontamination agent is rendered harmless by the antagonist.
- the introduction of a mist or aerosol containing the antagonist may be delayed until after the peroxide has achieved a desired decontamination effect.
- the aerosol containing the antagonist may be introduced simultaneously with (or even prior to) the peroxide.
- the deactivation may be achieved by nebulsing a protein denaturant such as, for example, solutions of urea, ethanol, chlorine or other halogen, copper salts or zinc salts.
- a protein denaturant such as, for example, solutions of urea, ethanol, chlorine or other halogen, copper salts or zinc salts.
- Preferred embodiments of the invention envisage a chamber which may be a vehicle, building, warehouse or such like containing a contaminant either as an aerosol, vapour or surface deposit.
- An embodiment of the invention is then introduced as an aerosol into the space and deactivates the contaminant, for example by oxidation in the case of an oxidizing decontaminating agent.
- the decontaminating agent is in turn rendered innocuous by introduction of a suitable antagonist in an aerosol form.
- the decontaminating agent is hydrogen peroxide
- the antagonist converts any residual peroxide into water and oxygen in a short time.
- the aerosol may be used in open spaces using fogging devices to generate the aerosol and in this case the aerosol is desirably self inactivating as has been herein discussed.
- Mustard gas for example is readily oxidized to bis (2-chloroethyl)sulfoxide. However it can be neutralized with secondary amines or ammonia for which acids provide a convenient antagonist. Mustard gas also reacts with carboxylic acids (for which alcohols provide a convenient antagonist) to form esters of thiodiglycols. Mustard gas also forms quaternary ammonium compounds with imidazoles. Proteins and anionic detergents provide a convenient antagonist.
- peroxides peracetic acid and oxy halides are preferred for use in the invention
- peroxides other than hydrogen peroxide may be employed as the decontaminant without departing from this invention and indeed the invention can be applied to decontaminants other than peroxides for example peracetic acid, by suitable selection of antagonists.
- antagonists other than those exemplified may be employed including all those known for use in catalytic destructors for peroxides and including (but not limited to) other metal catalysts, metal oxides, or salts, or combinations of the foregoing; triethanolamine and similar reducing agent; catalases or other suitable enzymes and the like.
- Suitable antagonists may be formed in situ by reaction in the droplets from precursors and the kinetics of the formation reaction may be used to increase the induction time or affect the kinetics of reaction between decontaminant and antagonist.
- the antagonist need not be in liquid form but may be a suspension of microfine solid either formed in situ or nebulised as a suspension in a liquid carrier. Modifiers affecting the kinetics of the reaction between the antagonist and the decontaminant are not limited to those herein exemplified.
- the inventive concept lies in the combination of an antagonist as an aerosol with the decontamination agent. Those skilled in the art will have no difficulty in selecting suitable compositions for use as the decontamination agent and then to select a suitable antagonist given the teaching herein contained.
- the aerosol may be generated and distributed by any suitable means.
- the carrier gas need not be air but could be nitrogen, an inert gas or other suitable medium.
- Other variations will be obvious to those skilled in the art from the description herein contained and such variations are deemed to lie within the inventive concepts herein disclosed.
