What mode is the Incident Commander (IC) in upon arrival at a scene with an immediate life threat?

When the Incident Commander arrives at a scene with an immediate life threat, they typically enter a fast attack mode. This mode is characterized by the urgent need to address life-threatening situations quickly and effectively. The focus during a fast attack is on quickly assessing the situation and initiating immediate action to mitigate danger, such as rescuing individuals in peril or suppressing imminent threats.

In a fast attack mode, the IC leads the response with an emphasis on rapid solutions rather than detailed planning or broader command structure, which would be more typical in other modes. The immediate nature of the threat requires decisive actions, often relying on the first-in units to engage quickly before a full-scale command structure is established.

Other modes, such as investigation or command, suggest a more measured approach, which may not be appropriate in the face of a time-sensitive life threat. Unified command can also apply in more complex incidents involving multiple agencies but usually follows an initial assessment and prompt action. In contrast, a fast attack signifies the urgency and priority given to the immediate life threats encountered by the first responders.
