Decontamination buildings

This clearly imposes some risk, as well as a large responsibility on those in charge of the decontamination process. It is essential that staff are properly trained and that they adhere to the methods that they have been taught, even as pressure from those awaiting decontamination builds up. The need for staff from the security services, for example, the Police, to supervise queues of people and to maintain order is obvious. 

Canyon structure for containment of process equipment, which would be installed and replaced remotely by overhead cranes. This arrangement is most cost effective in that it provides for maximum use of building space since there is no need for space between process equipment Failed equipment can be replaced in less than one day and is then moved to separate maintenance shops within the canyon structure for decontamination and repair. 

About one third of the overall production was applied in buildings used as additives to dyes and joint sealers. Normally, the use of PCBs in the materials is not (more) known to the inhabitants or users of the houses. Only in the case of secondary contamination of ambient air or food detected by chance or by systematic search, those buildings were decontaminated. Spreading of PCBs into the environment was accelerated by mixing of used hydraulic or heat exchanger fluids...

Decontamination of JACADS will require chemical, mechanical, and thermal processing. The removal of critical structural components and systems from buildings will have to be planned to ensure structural stability. Residuals of any of the agents processed at JACADS (HD, GB, and VX) may be exposed during disassembly activities. These residuals will be harmful to anyone in the immediate area If they are vaporized, airborne agent concentrations could be harmful, so decontamination procedures for equipment, waste streams, and building materials must ensure that agent residues are destroyed, and the destruction must be verified. 

The MDB is a two-story, steel-framed building with thick, reinforced-concrete floors and most interior walls made of concrete and foam-core sandwich panels. Explosion containment rooms have 2-foot-thick reinforced concrete floors, walls, and ceilings. Because concrete is a porous material capable of absorbing agent, all concrete surfaces in the JACADS process areas were sealed with an epoxy coating. A total of 134,153 square feet of concrete will require decontamination (U.S. Army, 1999d). 

The closure activities at J AC ADS consist of decontamination and removal of process equipment and building structures and some soil removal and disposal. Although no requirement for groundwater treatment is anticipated at Johnston Island, other CSDP disposal sites might require groundwater treatment, which would affect the closure process and the ultimate postclosure monitoring at those sites. 

Chlorine dioxide is a yellow to reddish-yellow gas that can decompose rapidly in air. Because it is a hazardous gas, chlorine dioxide is always made at the place where it is used. Chlorine dioxide is used as a bleach at pulp mills, which make paper and paper products, and in public water treatment facilities, to make water safe to drink. In 2001, chlorine dioxide was used to decontaminate a number of public buildings following the release of anthrax spores in the United States. Chlorine dioxide is soluble in water and will rapidly react with other compounds. When it reacts in water, chlorine dioxide will form chlorite ion, which is also a very reactive compound. 

Because decontamination occurs after buildings have been evacuated and first responders have treated any casualties, it allows for some time lapse before decontamination begins. With some planning, damage can be minimized and the efficacy of the decontamination process can be maximized. For example, sensitive equipment, electronics, valuable artwork, and personal objects will require chemicals that are less harsh than those used to clean air ducts and walls. The lack of time sensitivity also allows the choice of a decontaminant that may have a longer reaction time, but that is more suitable for the surface or the ambient conditions suoh as humidity and temperature. Thus, it is best to obtain a suite of deoontamination methods. 

Many chemical companies produce decontamination agents. DuPont, for instance, makes chlorine dioxide, the material used to decontaminate the Hart office building after anthrax contamination. DuPont did not perform the decontamination, however, because they did not know the effect of that product on a building, its infrastructure, computers, papers, or even the carpet. Although DuPont makes both the carpet and the decontaminant, we have never investigated the interaction of the two products. This is the kind of new, integrated thinking that is called for.
