Which channel is primarily used on marine incidents involving multiple agencies and not monitored by FRCC?

• A. A12
• B. A11
• C. A10
• D. A13

Answer: (C)

For marine incidents that involve multiple agencies, a dedicated interagency channel is used to enable direct, rapid coordination among all responding partners. This channel is not monitored by FRCC, which keeps it clear for incident-specific communication and avoids crowding the primary dispatch lines. Using this channel allows fire units, coast guard, police, harbor patrol, and other agencies to share updates, request resources, and issue commands without routing everything through FRCC, speeding up decision-making and reducing potential miscommunication from channel congestion.

Other channels are monitored by FRCC and are intended for standard dispatch and single-agency operations. If those channels were used for multi-agency marine operations, FRCC would become involved in ongoing coordination, which could slow things down and blur communication. So the marine interagency channel not monitored by FRCC is the appropriate choice.
