Which role runs the incident and may delegate duties during larger incidents?

The correct role that runs the incident and may delegate duties during larger incidents is the incident commander. The incident commander is responsible for overall management of the incident, including establishing the incident objectives, strategies for achieving those objectives, and managing resources. This role is crucial in ensuring the incident response is organized, efficient, and effective.

In larger incidents, the incident commander evaluates the situation and makes decisions that can impact all personnel involved. They have the authority to delegate responsibilities to other officers to manage various aspects of the incident, such as staging, triage, or transportation. This delegation ensures that all operational tasks are handled efficiently, enabling a coordinated response to the incident's complexities.

Other roles, like the staging commander or transportation officer, focus on specific tasks or components of the operation rather than overall management, while the triage officer is concerned with assessing and prioritizing patients based on their medical needs. Therefore, the incident commander’s broad oversight and leadership position make it the correct answer in this context.
