What is the recommended perimeter distance for explosions?

The recommended perimeter distance for explosions is based on safety protocols designed to protect individuals from potential hazards associated with explosive events. The choice that specifies a perimeter of 1.5 times the distance from the farthest piece of debris is correct because it accounts for the unpredictable nature of explosions.

This recommendation acknowledges that debris from an explosion can travel significant distances, potentially posing a danger even beyond the immediate vicinity of the blast. By establishing a perimeter that is 1.5 times farther than the most distant projected debris, emergency responders create a more comprehensive safety zone that mitigates the risk of injury from flying objects.

In contrast, options that suggest a different distance may underestimate the potential impact radius of an explosion and fail to provide adequate protection. It is essential for responders to prioritize safety and ensure that appropriate measures are in place to safeguard themselves and any civilians present during such incidents.
