What is a 'radio check' and when should it be performed?

• A. A weather broadcast
• B. A test of radio transmission quality, performed at incidents and when establishing a new channel or crew
• C. A daily PPE inspection
• D. A test of air mask seal

Answer: (B)

A radio check is a test of a radio’s ability to transmit clearly on the assigned channel and to be heard by others. It confirms that the radio path works—from the microphone to the channel, through the antenna and battery—and checks that audio is clear and at an appropriate volume so teammates can understand each other. This check is done at incidents to verify communications before operations begin, and whenever a new channel or a new crew is established to ensure everyone is on the same frequency and can hear one another. It helps catch problems like poor signal, incorrect channel settings, or weak batteries early, so they can be fixed before critical work starts. It’s not a weather broadcast, a PPE inspection, or a test of an air mask seal, since those checks serve different safety purposes.
