S-130 Radio Communication 5

Question 1

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

Accepted Answer

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

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

Direct radio-to-radio communication without using a repeater

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

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

Answer

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