Which item is used for organizing personnel and resources during a mass casualty incident?

The item that is used for organizing personnel and resources during a mass casualty incident is triage tags. Triage tags are critical in emergency response as they help in identifying the severity of injuries to individuals and prioritize their treatment accordingly. By categorizing victims based on their medical need—such as immediate, delayed, or deceased—rescuers can effectively allocate limited resources to those who need them most urgently.

In mass casualty situations, where multiple victims may require care simultaneously, triage tags ensure that responders can quickly assess and manage the flow of patients based on established priorities. This organization is essential for minimizing confusion and ensuring that medical teams can operate efficiently under pressure.

While other options, such as communication devices, incident command charts, and emergency response handbooks, contribute to overall incident management, they do not specifically focus on the categorization and prioritization of casualties during a mass casualty event like triage tags do.
