What must be maintained for accountability of all responders?

Maintaining personnel and resource tracking systems is essential for ensuring the accountability of all responders during an incident. These systems allow incident commanders and response managers to identify who is on scene and what resources are available, facilitating effective coordination and communication. Tracking systems provide real-time updates, allowing for quick decision-making and ensuring that all personnel are properly accounted for throughout the incident response.

Moreover, these systems help in documenting the deployment of resources and personnel, which is critical for both operational efficiency and post-incident analysis. They contribute to safety by ensuring that all responders are known and that any missing personnel can be quickly identified, ensuring a thorough search if necessary.

In contrast, other options, such as resource allocation plans, logistics checklists, and incident cost assessments, serve important functions in incident management, but they do not directly address the accountability aspect in the same way that personnel and resource tracking systems do. While they support the overall operation, they are more focused on planning and logistics rather than the immediate accountability of responders on-site.
