What must you do with radio devices prior to commencement of the work assignment?

• A. They must be tested, with an exchange of voice transmissions with another radio
• B. They must be turned off
• C. They must be used on the main channel
• D. They must be kept on for all communication

Answer: (A)

Verifying radio readiness and reliability before starting work is essential. The required step is to test the radios and exchange voice transmissions with another radio to confirm both transmit and receive functions work on the assigned channel. This ensures you can reach crew members and supervisors and that the device is operating properly in the field, which is crucial for coordinating actions and calling for help if needed.

Turning the radios off would prevent any communication, using only the main channel isn’t specified as the pre-work requirement, and simply keeping radios on for all communication doesn’t verify functionality. The test and two-way transmission check is the proper way to confirm reliable communication before the assignment begins.
