What is the primary role of ARFF personnel during an aircraft incident?

The primary role of Aircraft Rescue and Fire Fighting (ARFF) personnel during an aircraft incident is to contain the fire and protect passengers. This responsibility encompasses several critical tasks, including quickly deploying fire suppression efforts to mitigate the threat of flames, ensuring the safe evacuation of passengers and crew, and providing medical assistance if needed.

ARFF personnel are specially trained to handle emergencies involving aircraft, where the potential for fires, hazardous materials, and mass casualties exists. Their immediate action is focused on minimizing harm and securing the scene to prevent further complications.

In contrast, investigating the cause of the incident is typically performed by accident investigation teams after the immediate dangers have been resolved. Facilitating aircraft maintenance operations does not pertain to the emergency response, as maintenance is a separate function involving the aircraft's upkeep, not its operation during crises. Lastly, providing passenger comfort and support is important but not the foremost responsibility in life-threatening scenarios where fire and safety are priorities.
