How far should individuals evacuate from a bomb with a capacity of 4000lbs?

In the context of bomb evacuation distances, the primary consideration is the blast radius that can produce significant damage and injury. For a bomb with a capacity of 4,000 pounds, which is quite substantial, safety guidelines suggest that individuals should evacuate a distance of at least 640 feet to minimize the risk of exposure to the blast wave, fragmentation, and secondary effects.

Evacuating 640 feet offers a buffer zone that helps ensure that individuals are far enough from the potential explosion to reduce the likelihood of injury and increase overall safety. This assessment takes into account the explosive properties of such a device, including the range of its lethal and non-lethal effects, which can greatly vary based on environmental factors like urban settings or open spaces.

Other distances suggested in the choices may not provide adequate safety regarding the psychological and physical effects resulting from a blast of this magnitude, hence emphasizing why the specified 640 feet is the recommended distance for evacuating from a bomb of this size.
