What should you do if the radio fails and you cannot communicate with the dispatcher?

• A. Use contingency procedures, attempt other communications, and notify supervisor.
• B. Continue as if the radio works.
• C. Shout for help across the car.
• D. Wait until someone notices.

Answer: (A)

When primary communication fails, you must follow contingency procedures to keep operations safe and under control. This means first trying other ways to reach the dispatcher or a supervisor using alternate channels or methods provided in the rules. You would then notify a supervisor about the failure so they can issue instructions, coordinate actions, and log the incident. These steps ensure that you don’t proceed blindly without guidance and that the situation is escalated properly.

Continuing as if the radio works isn’t safe because you won’t have the dispatcher’s instructions or authoritative guidance. Shouting for help across the car is not a reliable or official method and can cause confusion. Waiting to be noticed delays critical actions and could compromise safety.
