Which report would you consult to determine boundary coordinates of the contaminated area?

• A. CBRN 5 report
• B. CBRN 4 report
• C. CBRN 3 report
• D. CBRN 6 report

Answer: (A)

Mapping the boundary of a contaminated area relies on the document that provides the official perimeter and the exact coordinates used to delineate the hazardous zone. The CBRN 5 report is the primary reference for these boundary coordinates, including the perimeter description and the spatial data that define where the contamination ends. This information is essential for setting safe distances, planning entry points, and organizing decontamination corridors, so responders can operate with a clear, enforceable boundary. The other reports cover different aspects of the incident—such as initial incident details, hazard information, or follow-up actions—and do not serve as the authoritative source for boundary delineation.
