These compounds can loosen or bind contaminants and so remove them from a surface. The friction of scrubbing also aids in decontamination of the skin during hand washing. The different tendencies of chemicals to dissolve in water a property known as solubility affects the efficiency of a decontaminant. For example, a longer period of decontamination is needed when using a compound that is not readily soluble in water. This problem can be somewhat overcome by the use of microemulsions, which are essentially very small droplets of the decontaminant.
The droplet coat is a material that is less water-soluble. The effect is best seen when oil is added to water. Then, a sheen of oil appears on the water, rather than a homogeneous oil-water mixture. If a contaminant is not water soluble, it will quickly partition into the hydrophobic "water-hating" decontaminant portion of a microemulsion. This can speed up the action of a decontaminant. Microemulsions can be applied to a contaminated surface as a spray, which can be washed off later.
Thermal methods. Thermal decontamination is the use of heat to vaporize those chemical contaminants that will readily convert from a liquid to a gas in the presence of heat. Both water- and alcohol-based chemicals can exhibit this behavior. Water can also be heated, even to the extent of being converted to steam.
Hot water or steam treatment can be an efficient means of decontamination of greasy or oily contaminants. The use of moist heat, as in the laboratory sterilization unit called an autoclave, disrupts chemical bonds in many microorganisms, killing them. Unfortunately, certain noxious bacteria that form spores i. Hot air is another useful decontaminant for compounds that can be volatilized.
This method is useful for situations where a spill can be isolated and treated over a longer period of time. In a battlefield situation, other more urgent methods are preferable. Nuclear decontamination in a battlefield site, to date only applicable in the Japanese cities of Hiroshima and Nagasaki in the waning days of World War II, necessitates the removal, burial, or storage of the contamination. However, in sites such as decommissioned nuclear power plants or weapons manufacturing facilities, the less concentrated amounts of radioisotopes that are encountered can be more systematically decontaminated.
Nuclear decontamination consists of the removal of the contaminating radioisotope. Removal can be accomplished by the use of water-soluble chemicals i. The specter of contamination with agents, in particular biological agents, was seared into the public consciousness in the latter months of Then, U. Postal Service. The concern over the use of biological weapons has not abated since that time.
Indeed, the possibility of biological attack, and so the need for rapid decontamination, was one of the paramount concerns of U. Suspected exposure to an aerosol of a dangerous microorganism should be dealt with promptly. The exposed clothing should be taken off and safely contained so as not to contaminate bystanders or medical personnel. It may be necessary to destroy clothing depending on the suspected contaminant.
For example, spores of the anthrax bacteria can cling to clothing and retain their potential for infection for decades. Exposed skin should be decontaminated. The best strategy is to use soap and water with diligent scrubbing for at least 30 seconds.
The use of diluted household bleach is acceptable. Decontamination in the case of biological exposure is typically done in an isolated facility, where the access of personnel is tightly controlled, and the outgoing air can be filtered to prevent the spread of the biological agent. Such facilities are even used in the battlefield setting. In battlefield settings such as Iraq, the military can use a dried resin known as M This resin is a dry black carbon containing material that decontaminates by absorption and physical removal of the chemical agents from the victim.
M resin is particularly useful for localized "spot" decontamination of exposed skin. Organization of a military treatment area. Part of military strategy in conflicts where there is a potential for the use of biological or chemical weapons, as in the Iraq conflict of , is the establishment of medical treatment facilities. In the battlefield a facility is divided into two zones. One zone the "dirty" zone is where contaminated personnel and equipment are segregated.
The other, "clean" zone is kept free from the contaminating agents. The transition area between these zones, which is called the hotline, keeps contaminated people including casualties and equipment out of the clean side until decontamination is completed. Triage, emergency treatment, and decontamination are done in the dirty zone. The emergency treatment station essentially treats patients as best as possible and stabilizes them for movement to the clean zone operation theatre, or evacuation to a hospital.
Any decontamination is done in the dirty zone, with more substantive medical procedures being done in the clean zone. For example, in the aftermath of the anthrax attacks in the U. In the event of a large scale contamination, such as the "dusting" of anthrax spores over a metropolitan area, large numbers of causalities would likely result, as decontamination strategies for such masses of people are still in the planning stages.
The past deployment of chemical and biological weapons by the government of Iraq under Saddam Hussein, and the inconclusive findings of the United Nations weapons inspectors who were present in Iraq in —, heightened concerns for the possible use of such weapons during the war between Iraq and coalition forces of the United States and the United Kingdom.
In the —88 war with Iran, Iraq deployed chemical weapons that affected an estimated , Iranians, killing about 10, people. Even today, some 1, people are considered to be moderately to severely ill because of these attacks. Another decontamination effort will be necessary to deal with the oil wells that have been set ablaze by Iraqi soldiers in the conflict. The residue given off by the blazing wells in sufficient numbers could be an environmental disaster, and is unhealthy to breathe.
Unfortunately, decontamination is virtually impossible, other than to extinguish the blazes and to clean up the terrain immediately surrounding the wells once they have been extinguished. Contamination of the drinking water supplies of southern Iraqi towns such as Safwan and Zubayr makes the possibility of disease more immediate. Post-war decontamination efforts involved the isolation and treatment of the contaminated surface and ground waters.

All the parts of speech in English are used to make sentences. All sentences include two parts: the subject and the verb (this is also known as the predicate). Decontamination is a pre-treatment procedure. It allows removal with a decontaminating agent of the most contaminated part of a material or structure so that the remaining part can be reused or discharged as non-radioactive waste. Decontamination processes as a rule produce secondary waste streams, which also need to be treated and conditioned. 44 45 46 47 48
