What does the green traffic cone signify in the decontamination setup?

The green traffic cone in the decontamination setup serves as an indicator for the location of the Decon Hose Line. Its use is crucial for ensuring that personnel and equipment can easily identify where they can wash off contaminants after a hazardous incident. The visual cue helps in maintaining an organized and efficient decontamination process, allowing responders to quickly access the necessary resources while also ensuring their safety.

The other options, while relevant in various contexts within emergency response and management, do not relate specifically to the function of the green traffic cone. For instance, emergency exits are typically marked with standard signage that ensures clear visibility and should be easily identifiable regardless of other markers like cones. A rehab station, which is designed for personnel recovery and medical evaluation, would generally be marked differently to convey its purpose. The hot zone boundary is usually defined through more significant and visible barriers or tape, rather than cones that are specific to decontamination activities.
