What does Bounce and Bypass locate?

• A. General dimensions of contamination
• B. General boundaries
• C. Hazard level
• D. Routes of egress

Answer: (B)

Bounce and Bypass is about finding the outer limits of the hazard—the general boundaries of where the danger starts and ends. The idea is to quickly establish a perimeter so responders know where it’s safe to operate and where to avoid crossing, without needing precise measurements of every contaminant detail. The “bounce” part involves checking areas as you move between suspected hot and safe zones to see where exposure indicators change, helping to sketch the outer boundary. The “bypass” part helps verify you can move around obstacles and still stay outside the hazard, reinforcing that boundary.

This is why it’s the best choice: it’s focused on outlining the extent of the hazard area itself, not on measuring how large the contaminated zone is, assessing how severe the hazard is, or identifying the best egress routes for movement once you’re already outside the danger.
