Which statement best describes the role of decontamination corridors at the scene of a chemical exposure?

• A. They serve as a primary triage area for all contaminated patients.
• B. To prevent cross-contamination of responders and hospital staff; provide a controlled decontamination area.
• C. They are optional and rarely used during major incidents.
• D. They are used to store PPE equipment only.

Answer: (B)

Preventing spread of chemical contaminants during cleanup is the main idea behind a decontamination corridor. This space acts as a controlled buffer between the contaminated scene and the rest of the incident response, allowing patients to be decontaminated without contaminating responders or hospital staff. It lets contaminated clothing be removed, washing occur, and runoff be contained, keeping the flow of people and water from crossing into clean areas. Triage happens separately and can occur outside this corridor, but the corridor’s purpose is decontamination and contamination control, not patient sorting. It’s not optional or rarely used in major incidents, since decontamination is essential for safety. And it isn’t simply storage for PPE—PPE handling occurs in appropriate zones; the corridor’s primary role is the actual decontamination process and preventing cross-contamination.
