What is the shelter-in-place zone distance for a car bomb?

The appropriate shelter-in-place zone distance for a car bomb is based on the potential blast radius and fragmentation from an explosion. The selected range of 321 to 1899 feet accounts for the varying degrees of danger associated with different types of explosive devices, particularly those that may be used in a vehicle. This range helps ensure that individuals are kept at a safe distance to minimize the risk of injury from the shockwave or flying debris.

In contrast, the other options either fall below or exceed the recommended safety range. Distances that are too short may not provide adequate protection from the effects of a car bomb, while those significantly longer may exceed necessary precautions, making them impractical for immediate response planning. Proper training and adherence to safety guidelines ensure that law enforcement and first responders can effectively mitigate risks in these situations.
