Questions: What is the major tool the IC uses to control incident scene communications? A. Utilizing command post position and staff B. Quickly assigning additional radio channels to branch officers C. Assigning Rapid Intervention Crews D. Assign a support officer to manage all tactical radio traffic

The answer is the first one (A): Utilizing command post position and staff.

Explanation for each option:

A. Utilizing command post position and staff - This is correct because the Incident Commander (IC) typically uses the command post and its staff to manage and control communications at the incident scene. The command post serves as the central hub for coordinating all activities and ensuring effective communication among all units involved.

B. Quickly assigning additional radio channels to branch officers - While assigning additional radio channels can help manage communications, it is not the primary tool for controlling incident scene communications. It is more of a supplementary measure.

C. Assigning Rapid Intervention Crews - Rapid Intervention Crews (RICs) are primarily assigned for the safety and rescue of firefighters in distress, not for managing communications.

D. Assign a support officer to manage all tactical radio traffic - Although assigning a support officer can help manage radio traffic, it is not the major tool used by the IC. The command post and its staff play a more central role in controlling communications.

Summary: The major tool the IC uses to control incident scene communications is utilizing the command post position and staff.
