How many identification levels are defined for CBRN hazard identification?

• A. 6
• B. 3
• C. 4
• D. 5

Answer: (C)

A tiered approach to CBRN hazard identification guides responders from initial observations to a definitive conclusion as more information becomes available. It starts with noticing signs that a hazard might be present and then moves to a broad classification to place the threat in a general category. Next comes more specific identification, narrowing down to a probable agent type or characteristic. Finally, analytical testing and verification confirm exactly what is present. This progressive structure helps responders tailor protective measures, decontamination, and response actions to the level of certainty at each stage, balancing speed with accuracy. That is why this staged framework is the standard practice, rather than relying on a single, non-specific assessment.
