What class of ARFF vehicle requires at least 3,000 gallons of water/AFFF?

• A. Class II
• B. Class III
• C. Class IV
• D. Class V

Answer: (C)

The classification of ARFF (Aircraft Rescue and Firefighting) vehicles is determined by their water and firefighting agent capacity. Class IV vehicles are designed for large aircraft incidents and must carry at least 3,000 gallons of water or a combination of water and firefighting foam (AFFF). This capacity enables them to effectively tackle the risk of large-scale fires associated with firefighting operations at airports, especially during aircraft emergencies.

Vehicles in this class are equipped with powerful pumps and nozzles to ensure rapid firefighting response. This is crucial in minimizing the risk of fire spreading and ensuring the safety of passengers and crew, as well as protecting airport infrastructure.

In contrast, other classes have lower requirements for water and foam capacity, making them less suitable for the needs presented by larger aircraft incidents. Understanding these classifications helps ensure that airport firefighting capabilities are appropriately matched to potential emergencies, safeguarding effective and efficient responses.
