Which monitoring strategy is used to determine whether hazards remain in the area after a CBRN incident?

• A. Periodic
• B. Intermittent
• C. Random
• D. Instant

Answer: (A)

After a CBRN incident, hazards can linger and may change in intensity over time, so you need a monitoring approach that checks the area repeatedly at planned intervals. Periodic monitoring provides a scheduled sequence of measurements, allowing you to track trends in contamination or hazard presence and to decide when conditions have become safe enough for reentry or restoration work. It also supports resource planning and ensures that you don’t miss lingering pockets of danger, since assessments occur over time rather than just once. Intermittent monitoring, by contrast, happens sporadically and may miss persistent or reappearing hazards. Random monitoring lacks a fixed pattern, which can leave gaps in coverage. Instant monitoring implies a single, immediate check and does not provide information about whether hazards persist or return over time.
