Which action is NOT part of the four Cs when responding to a bomb threat?

The four Cs when responding to a bomb threat are aimed at ensuring the safety of individuals and effectively managing the situation. These actions include Confirming the threat, Clearing the area, and Closing off access to the site.

The action of Communicating is indeed crucial during a bomb threat scenario, as it involves sharing information with authorities and ensuring that proper procedures are followed. However, in the context of the four Cs, Communicating is not one of the primary actions outlined. Instead, the emphasis is placed on Confirming the existence of a threat, Clearing the area to ensure safety, and Closing off the area to prevent unauthorized access and further risk. Thus, the correct response here highlights that Communicating, while important, is not formally recognized as one of the four Cs in this specific protocol.
