What is the minimum withdrawal distance in case of potential detonation?

• A. At least 2,000 ft.
• B. 50 ft.
• C. 5,000 ft.
• D. 200 ft.

Answer: (A)

When there is a potential detonation, the priority is to protect responders from blast overpressure, flying debris, and heat by creating a very large safety buffer. This minimum withdrawal distance is set as a baseline standoff that covers the uncertainties of real-world devices and configurations, giving a generous margin so people, vehicles, and equipment aren’t in the most dangerous zone. Shorter distances would place personnel within the expected area where fragments and pressure effects could cause injury or damage, even if the device isn’t fully understood. A larger, conservative distance helps ensure safety across a range of detonation scenarios, before incident specifics can be fully evaluated. In practice, responders start with this substantial buffer and then adjust based on the situation, but as a baseline it represents the safest, most protective choice.
