Read the passage, then answer. PASSAGE: At an incident involving a spilled chemical, the Bridgeport Fire Department divides the scene into three control zones. The hot zone is the area of actual contamination; only crews wearing the protective level named by the Hazard Officer may enter it. The warm zone surrounds the hot zone and contains the decontamination corridor, where crews leaving the hot zone are washed. The cold zone is the outermost area and holds the command post, the rehabilitation area, and the staging area for arriving units. All personnel entering or leaving the hot zone must pass through a single access control point located in the warm zone. Reporters and civilians are kept outside the cold zone entirely. According to the passage, where is the decontamination corridor located?
