Which organization has line authority to oversee the management of multiple incidents being handled by separate Incident Command organizations?

The correct choice is Area Command, which is specifically designed to oversee the management of multiple incidents that are being handled by different Incident Command organizations. This structure is particularly beneficial in situations where incidents are geographically dispersed or when resources are being shared across several incidents.

Area Command provides a higher level of coordination and strategic oversight. It does not manage the individual incidents directly but rather provides guidance and resource allocation to the Incident Commanders of each incident. This facilitates effective management by ensuring that all incidents are aligned with larger organizational goals and that resources are optimized across various sites.

Unified Command involves the collaboration of multiple agencies and organizations to manage a single incident, making it effective for coordinating efforts. However, it does not have the oversight capacity for multiple incidents like Area Command does.

Incident Command refers directly to the organization established to manage a specific incident, focusing on tactical operations rather than strategic oversight.

The Emergency Operations Center (EOC) serves as a central location for coordination and support during incidents but does not have the direct line authority over the incidents managed by Incident Command organizations. The EOC primarily supports Incident Commands by providing resources and information rather than overseeing them.

Thus, Area Command is the correct answer because it is set up specifically for the task of overseeing multiple incidents simultaneously
