Which of the following is a primary responsibility of ARFF personnel during an aviation emergency?

The primary responsibility of ARFF (Airport Rescue and Fire Fighting) personnel during an aviation emergency is to extinguish fires and prevent fire spread. This is essential in minimizing the risks associated with aircraft fires, which can occur during crashes, emergency landings, or other incidents. Firefighters are specifically trained to handle the unique challenges of aircraft fires, including the high volatility of aviation fuels and the complex structures of aircraft. Their swift and effective actions can significantly mitigate the impact of fire, protect lives, and safeguard the aircraft.

While managing traffic, providing first aid, and coordinating with law enforcement are important tasks during emergencies, they do not represent the core function of ARFF personnel. Their specialized training and equipment are focused predominantly on firefighting and rescue operations, making the prevention and control of fires their top priority.
