What is the purpose of decon corridors in hazmat response?

• A. To provide a controlled path for contaminated personnel and equipment from hot zone to decon areas, preventing cross-contamination
• B. To expedite chemical synthesis
• C. To route traffic around incident
• D. To keep victims inside hot zone

Answer: (A)

Decon corridors exist to create a controlled, one-way path for anything contaminated—people, gear, and other materials—from the hot zone into decontamination areas. This setup keeps contaminants from spreading into clean areas, supporting a staged, effective decon process and protecting responders and others from cross-contamination. It also enables proper PPE doffing, collection and containment of wash water, and prevents backflow of contaminants into noncontaminated zones. The other options don’t address moving and removing contamination through a dedicated, controlled route, so they don’t fit the purpose.
