What is the purpose of a decon corridor and how should it be arranged?

• A. For storing clean gear away from hot zone; single entry.
• B. A public viewing area.
• C. To park vehicles.
• D. To move contaminated individuals/equipment from hot to cold zones; arranged as a controlled pathway with separate entry/exit and containment.

Answer: (D)

The decon corridor is the controlled passage that allows contamination to be removed as people and equipment move from hot (contaminated) areas toward cold (clean) areas. It should be arranged as a one-way, contained pathway with a separate entry from the hot zone and a dedicated exit into the cold zone, so contaminants can’t flow back or bypass the decontamination steps. Inside the corridor, decon steps (such as gross decon followed by more thorough washing) are performed, and the space is designed to contain wash water and debris, with barriers to prevent spread. This setup protects responders and the environment by maintaining a clear, controlled flow and preventing cross-contamination. It isn’t for storing clean gear, a public viewing area, or parking vehicles.
