  1. When establishing communication with a new radio system on an incident, what should a firefighter do before their first transmission?

    Answer: Perform a radio check to confirm the channel is working and readable

    Performing a radio check confirms the system is functioning and the signal is clear before operational messages are transmitted.

  2. A spot fire is reported downhill and to the east of Division A. How should this be communicated over the radio?

    Answer: 'Division A to Operations: spot fire approximately 200 yards downhill and east of our position, approximately 0.1 acres'

    Effective spot fire reporting includes the caller's identity, location relative to known landmarks, estimated size, and urgency.

  3. What does 'talk-around' mode mean in the context of portable radios on a wildland fire?

    Answer: Direct radio-to-radio communication without using a repeater

    Talk-around (also called direct or simplex mode) allows radios to communicate directly without a repeater, useful for short-range local coordination.

  4. Which of the following best describes the 'read back' technique in radio communication?

    Answer: The receiving unit repeats the message back to the sender to confirm accuracy

    The 'read back' technique requires the receiver to repeat critical messages so the sender can confirm the information was received correctly.

  5. During rapidly changing fire conditions, which radio practice is most critical to firefighter safety?

    Answer: Providing immediate, real-time updates on fire behavior and crew location

    Real-time updates on changing conditions allow supervisors and crews to respond immediately to threats rather than reacting after the fact.

  6. What is the significance of the ICS position 'Communications Unit Leader' having a copy of the current Incident Action Plan (IAP)?

    Answer: The IAP contains the ICS-205, which outlines radio assignments the COML must implement

    The IAP includes the ICS-205 Communications Plan, which the COML uses to set up and manage radio assignments for the operational period.

  7. A firefighter hears a MAYDAY transmission on their radio. What is the correct immediate response?

    Answer: Clear the channel immediately and allow emergency traffic to proceed

    Upon hearing a MAYDAY, all non-emergency users must immediately stop transmitting and keep the channel clear for emergency communications.
