What is the required water capacity for Class 5 ARFF vehicles?

• A. 1000-1500 gallons
• B. 1500-2500 gallons
• C. 2500-3000 gallons
• D. 500-1000 gallons

Answer: (B)

The correct range for the required water capacity for Class 5 ARFF (Aircraft Rescue and Firefighting) vehicles is indeed 1500-2500 gallons. This capacity is critical as it allows these vehicles to effectively respond to aircraft emergencies and fight fires that may occur during an incident involving an aircraft.

The Class 5 vehicles are designed for airports with a certain level of operations, and the water capacity supports a prolonged firefighting effort, which is necessary for dealing with potential large-scale incidents. This level of capacity is also in accordance with national standards and regulations that guide ARFF response capabilities, ensuring that fire departments are well-equipped to combat fuel-fed fires, which can burn intensely and require significant amounts of water to control.

In contrast, the other options fall outside of the specifications needed to safely and effectively respond to emergencies within the aviation environment. Lower capacities would not provide sufficient firefighting resources, potentially compromising response effectiveness in critical situations.
