Under what condition is the threat to use a weapon of mass destruction classified as F-3?

The classification of a threat to use a weapon of mass destruction as F-3 is associated with the potential impact on public safety and security. In this context, causing an evacuation is a significant marker because it reflects the immediate danger posed to a large number of people. When the threat is so severe that it necessitates the evacuation of an area, it serves as a vital indicator of the seriousness of the threat, which aligns with the classification of F-3.

Evacuations are typically ordered in scenarios where there is an imminent risk to life or health, underscoring the intent to protect individuals from the potential consequences of such a threat. Therefore, this condition not only aligns with the classifications used in assessing threats but also emphasizes a proactive response to safeguard the community.
