Technicians should perform post Decon checks as individuals exit the ______.

• A. Hot zone
• B. Contamination area
• C. Decon corridor
• D. Support area

Answer: (C)

Post-decon checks are done as personnel exit the decontamination process, in the decon corridor. This corridor acts as the controlled transition between the contaminated/decon area and the clean or support area, allowing final verification that PPE removal was performed correctly and that no residual contamination remains on the person or equipment. Conducting these checks here prevents any contamination from being carried into the safe zone and ensures the individual and their gear are ready to move on.

The hot zone is where the hazards and work occur, not where doffing verification happens. The contamination area isn’t the defined transition for post-decon checks, and the support area is the clean space beyond the decon corridor, entered after post-decon verification.
