What is a key precaution to take with personnel during a wheel brake failure?

During a wheel brake failure, the safety of personnel is the top priority. Evacuating them from the immediate area minimizes the risk of injury in case the aircraft begins to move unexpectedly or experiences additional mechanical issues. In such situations, brake failure can lead to uncontrolled movement, posing a significant danger to anyone nearby. By removing personnel from the vicinity, you significantly reduce the risk of accidents and ensure their safety.

Remaining near the aircraft could expose personnel to harm if the aircraft rolls or shifts position unexpectedly. Asking them to prepare for take-off during a brake failure is highly unsafe, as the aircraft is not in a controlled state ready for departure. Lastly, while it's essential for personnel to be informed about the aircraft's condition, simply ensuring awareness is insufficient to protect them during a critical technical failure like a brake failure. Prioritizing evacuation is the most effective precaution to take in such a scenario.
