Process Decontamination

Decontamination is a process that is site specific. Meteorological conditions may, at times, have an effect on the decontamination process. Rainy conditions may produce mud. The mud not only makes the work more... 

A tremendous amount of work has to be done to make sure that effective decontamination is accomplished. However, the site decontamination process should be constantly reviewed to make sure of its effectiveness. This process should be continuous. 

A JHA should be conducted and hazards associated with the decontamination process should be identified to determine the appropriate types of PPE for decontamination workers. This information should be incorporated in the safety plan. 

For many operations, workers are assigned to assist in conducting decontamination of workers wearing Level A or B PPE during the decontamination process. Decontamination workers stationed at the front end of the decontamination line may require more protection from chemical and radiological contaminants than decontamination workers assigned to the latter stages of decontamination. 

The hazardous waste standard requires employers to make certain that when showers are a necessary step in the decontamination process, their employees shower at the end of their work shift and when leaving the hazardous waste site. Sanitation-related showers (unlike decontamination showers) are understood to be voluntary. Decontamination and emergency showers should be located close to the worksite. Sanitary showers may be located at some distance from the worksite. A statement in the safety plan encouraging good personal hygiene and daily showers is a good idea. In addition, workers should be encouraged to shower daily even if no shower is available at the worksite.

Decontamination procedures must provide an organized process by which levels of contamination are reduced. The decontamination process should consist of a series of procedures performed in a specific sequence. Each procedure should be performed at a separate station in order to prevent cross-contamination. The sequence of stations is called the decontamination line. 

The national organic certification bodies will also provide useful information on food processing standards in organic food production. In addition, there are publications that have reviewed decontamination processes and disinfection procedures used in the fresh produce industry. Some of these are also listed below. 

Casualties should be warned that there is a mild reaction between water and the agent and that they could experience a burning sensation during the decontamination process. 

Once the remains have been thoroughly decontaminated, process the body according to established procedures for handling potentially infectious bodies. Use appropriate burial procedures.

After the decontamination process not the whole amount of the mustard agent is decontaminated and 2-3% of the preliminary quantity remains bonded to textile. Comparing both evaporation and decontamination the temperature has a significant influence on the kinetics of the process. At of 60°C mustard agent is not fully decontaminated in the researched period of time.

Decontaminate the skin using soap and water. These products are toxic materials therefore, decontamination is extremely important. The removal of clothing containing liquid or vapor laden clothing is a part of the decontamination process. 

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.

The Advanced Recovery Systems, Inc. (ARS) soil washing technology is an ex situ soil decontamination process for decontaminating radioactively contaminated soil. ARS developed the technology to treat contaminated soil. 

The solutions used in the decontamination process can be destroyed, resulting in greater than 99.99% destruction of all organics present. The destruction process precipitates the contaminants, and then removes them by filtration and ion exchange for further processing.
