SRT Radio & Hand Signal Communication 5

Question 1

In a swiftwater night operation, which adaptation replaces standard hand signals for team communication?

Accepted Answer

Chemlight or flashlight signals using agreed-upon light patterns

Answer

Chemical lights or flashlights with pre-briefed signal codes replace visual hand signals during night rescue operations.

Question 2

What does 'net control' mean in swiftwater rescue radio operations?

Accepted Answer

The station responsible for managing traffic flow on the radio net

Answer

Net control manages who speaks on the radio channel, preventing simultaneous transmissions and maintaining order.

Question 3

A rescuer draws a finger across their throat (throat-slash gesture) during a swiftwater operation. This signals:

Accepted Answer

Cut the rope / stop all action immediately

Answer

A throat-slash gesture universally means 'cut' — in rescue contexts it signals cut the rope or abort the current action.

Question 4

What is the primary reason GPS coordinates should be communicated phonetically using the NATO alphabet on rescue radios?

Accepted Answer

To prevent misinterpretation of similar-sounding letters in poor radio conditions

Answer

NATO phonetics eliminate confusion between similar-sounding letters (e.g., B/D/E/P) that radio noise can make indistinguishable.

Question 5

During a Type I swiftwater incident, which radio channel assignment is standard ICS practice?

Accepted Answer

Separate channels for command, tactical, and logistics with a designated dispatch channel

Answer

ICS requires channel separation by function (command, tactical, logistics) to prevent traffic congestion at complex incidents.
