Where can contaminants be found?
Contaminants can be located either on the surface of personal protective equipment or permeated into the PPE material. Surface contaminants may be easy to detect and remove; however, contaminants that have permeated a material are difficult or impossible to detect and remove. If contaminants that have permeated a material are not removed by decontamination, they may continue to permeate to either surface of the material where they can cause an unexpected exposure.
Where should decontamination facilities be located?
At a hazardous waste site, decontamination facilities should be located in the Contamination Reduction Zone (CRZ), i.e., the area between the Exclusion Zone (the contaminated area) and the Support Zone (the clean area) as shown in 3.
What is the purpose of the decontamination chapter?
In addition, this chapter provides general guidelines for designing and selecting decontamination procedures at a site, and it presents a decision aid for evaluating the health and safety aspects of decontamination methods. The chapter does not cover decontamination of radioactively contaminated personnel or equipment. A health physicist should be consulted if this situation arises.
What is decontamination in hazardous waste?
Decontamination - the process of removing or neutralizing contaminants that have accumulated on personnel and equipment - is critical to health and safety at hazardous waste sites. Decontamination protects workers from hazardous substances that may contaminate and eventually permeate the protective clothing, respiratory equipment, tools, vehicles, and other equipment used on site; it protects all site personnel by minimizing the transfer of harmful materials into clean areas; it helps prevent mixing of incompatible chemicals; and it protects the community by preventing uncontrolled transportation of contaminants from the site.
Why is decontamination important?
While decontamination is performed to protect health and safety, it can pose hazards under certain circumstances. Decontamination methods may: Be incompatible with the hazardous substances being removed (Le., a decontamination method may react with contaminants to produce an explosion, heat, or toxic products).
How many stations are there in a decontamination line?
1.3 The maximum decontamination procedures for all levels of protection consist of specific activities at nineteen stations. Each station emphasizes-an important aspect of decontamination. When establishing a decontamination line, each aspect should be incorporated separately or combined with other aspects into a procedure with fewer steps (such as the Minimum Decontamination Procedures).
Why is contact time important in decontamination?
Contact time. The longer a contaminant is in contact with an object, the greater the probability and extent of permeation. For this reason, minimizing contact time is one of the most important objectives of a decontamination program.
What is the transition zone between the contaminated area and the clean area?
The Contamination Reduction Zone lies outside the Hotline and serves as the transition area between the contaminated area (the Exclusion Zone) and the clean area (the Support Zone).
What is the boundary of the exclusion zone?
The Exclusion Zone is where the actual contamination occurs or could occur. The boundary of the Exclusion Zone is called the “Hotline, ” and should be clearly marked with lines, placards, hazard tape, or signs. Sometimes even physical barriers like fences or ropes are used around the Hotline to block off the Exclusion Zone.
What is the Contamination Reduction Corridor?
While the area of the Contamination Reduction Zone that is nearest the Hotline remains contaminated, the level of contamination decreases the further away you move from the Hotline in the direction of the Support Zone. Within the Contamination Reduction Zone is an area called the “Contamination Reduction Corridor.”.
What is the support zone?
The Support Zone is the outermost zone that borders the Contamination Reduction Zone. This is where administrative and other support personnel remain in order to regulate the activities happening in the other work zones and to oversee the operation at large.

These zones are established primarily to reduce the accidental spread of hazardous substances by workers or equipment from contaminated areas to clean areas. Safety zones specify: The type of operations that will occur in each zone;
What is a support zone?
