Which of the following is a primary function of ARFF vehicles?

• A. Passenger transport
• B. Runway maintenance
• C. Fire suppression
• D. Security enforcement

Answer: (C)

The primary function of Aircraft Rescue and Firefighting (ARFF) vehicles is fire suppression. These specialized vehicles are designed to respond quickly to fires and emergencies that can occur during aircraft operations, particularly during takeoff and landing phases. Equipped with powerful fire suppression tools and materials, ARFF vehicles can deliver foam, water, and other firefighting agents to effectively extinguish flames and protect both the aircraft and any individuals on board.

While ARFF vehicles may play a role in supporting functions like airport safety and emergency response, their core purpose revolves around providing immediate fire protection and ensuring the safety of passengers and crew. The design and equipment of ARFF vehicles reflect this focus, differentiating them from vehicles used for passenger transport, runway maintenance, or security enforcement, which do not have the same urgent firefighting capabilities.
