During a mass casualty incident, what is one of the initial tasks for the first officer on-scene?

In a mass casualty incident, one of the initial tasks for the first officer on-scene is to communicate with dispatch. This step is vital because it allows for the rapid mobilization of additional resources and personnel needed to manage the situation effectively. By informing dispatch of the situation, the officer helps ensure that every available unit can be coordinated and dispatched to the scene, which is critical in an environment where numerous injuries may require immediate attention.

Moreover, communicating with dispatch allows for the establishment of a command structure, which is essential for managing the chaos that typically accompanies such incidents. This coordination aids in the effective allocation of resources, such as ambulances and medical teams, while also keeping other emergency services informed of the evolving situation.

The other tasks mentioned, such as treating the most seriously injured, recording patient information, and assessing the location of emergency exits, are important but typically fall into the following phases after initial communication. The first response focus is on managing the scene and ensuring that adequate help is on the way, which keeps all responders safe and organized in a high-stress environment.
