Gross decontamination typically occurs within a controlled decontamination corridor. This designated area is specifically set up to manage the safe removal of contaminants from individuals who have been exposed to hazardous materials. It is designed to control the environment, ensuring that hazardous substances do not spread to non-contaminated areas and providing the necessary equipment and procedures to effectively decontaminate personnel.

A controlled corridor allows for the systematic and organized process of decontamination, often involving the use of water, soap, and other appropriate agents to remove harmful substances from clothing and skin. The setup includes proper containment measures to prevent cross-contamination and can accommodate multiple individuals at once, facilitating a more efficient response.

The other locations, such as laboratories, public shelters, or general outdoor environments, do not provide the necessary containment and structured environment required for effective gross decontamination, potentially leading to the unsafe spread of contaminants or inadequate decontamination procedures.
