Where is the decontamination zone located?
Contamination Reduction Zone
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 operations occur in the support zone?
The Support Zone is also where recordkeeping, data storage, inventories, maps, and other useful information is produced and stored in order to support the ongoing activity in the other two work zones.
Which of the following are basics of decontamination?
Methods of decontamination include isolation of contaminants, physical removal, and chemical removal. This process entails removing contaminated equipment and protective clothing and leaving it at the decontamination area.
What is the initial isolation zone?
The Initial Isolation Zone defines an area SURROUNDING the incident in which persons may be exposed to dangerous (upwind) and life threatening (downwind) concentrations of material.
What is the meaning of exclusion zone?
An exclusion zone is a territorial division established for various, case-specific purposes. Per the United States Department of Defense, an exclusion zone is a territory where an authority prohibits specific activities in a specific geographic area (see military exclusion zone).
Which three operating control zones are typically established to effectively control the perimeter at an incident?
Hot, warm, and cool zones are located inside the isolation perimeter. Should be established through air monitoring, and clearly marked and posted on the ICs tactical worksheet.
What are the 3 steps to decontamination?
The three processes are:
- Cleaning.
- Enhanced cleaning.
- Disinfection.
What are the decontamination and support areas?
The decontamination and support areas are established within the Warm Zone, also referred to as the Contamination Reduction Zone. Decontamination involves thorough washing to remove contaminants. It should be performed in an area upwind of the Hot Zone. An area that is uphill, with good drainage, and easily accessible for responders is preferred.
What is the process of decontamination?
The entire process of decontamination is directed toward confinement of the contaminant within the Warm Zone and controlling it within the decontamination area. Different chemicals have differing Hot Zones depending on the toxicity and flammability of the chemical.
What are the hazmat zones?
Know your hazmat zones. This synthetic rubber also provides the highest permeation resistance to nerve gases, such as Sarin or mustard gasses, and water vapors. The warm zone is the circular area around the Hot Zone for decontamination. If decontamination is not performed onsite, a hospital ER may become the warm zone.
What is the contamination reduction zone?
The contamination reduction zone (or warm zone) is the transition area between the exclusion and support zones. This area is where responders enter and exit the exclusion zone and where decontamination activities take place.
