What resource management task involves activating personnel and resources for an incident?

The resource management task that involves activating personnel and resources for an incident is known as "Mobilize." This task is critical in the incident management process as it focuses on the deployment and immediate engagement of resources, including personnel, equipment, and supplies, necessary to effectively respond to an incident.

Mobilization ensures that the right resources are available at the right time and place, facilitating swift response and operational readiness. This is a key aspect of the National Incident Management System, which emphasizes the importance of prompt and efficient resource allocation during incidents to mitigate impacts and support response efforts.

Other tasks listed, such as ordering and acquiring resources or tracking and reporting them, are important parts of resource management but do not specifically pertain to the activation phase. Reimbursement and restocking are administrative tasks that occur after the incident, relating to financial management and resource replenishment.
