Which channel handles suppression incidents requiring four or fewer units and is monitored by FRCC at all times?

• A. A4
• B. A3
• C. A2
• D. A5

Answer: (A)

Understanding radio channel design for suppression incidents: a channel is set aside specifically for smaller incidents—four units or fewer—and FRCC is watching that channel continuously. This arrangement keeps busy channels clear, so units can communicate quickly and precisely about location, assignments, and status without overloading the main operations channels. The continuous FRCC monitoring ensures centralized control from the start, allowing rapid coordination if the incident grows or more resources are needed. Other channels are used for larger, more complex incidents or for different types of operations and may not be watched continuously for every small event, so they aren’t the best fit for four-or-fewer-unit suppression responses.
