What is the water capacity requirement for a Class IV ARFF vehicle?

• A. 1000 gallons
• B. 1500 gallons
• C. 2000 gallons
• D. 2500 gallons

Answer: (B)

The water capacity requirement for a Class IV Aircraft Rescue and Firefighting (ARFF) vehicle is indeed 1500 gallons. This classification is part of the National Fire Protection Association (NFPA) standards, specifically designed to ensure that firefighting vehicles are adequately equipped to handle emergencies related to aircraft incidents.

A Class IV ARFF vehicle is intended for protecting larger aircraft and is built to deliver significant fire suppression capabilities, which is reflected in its water capacity requirement. The 1500-gallon capacity allows the vehicle to provide sustained fire suppression efforts, which is vital in minimizing damage and potential loss of life during incidents.

In comparison, Class III ARFF vehicles would typically have lower capacity requirements. The other options available exceed the requirements outlined for Class IV, indicating that those capacities are either associated with larger or more specialized vehicles. This knowledge is critical for ensuring compliance with safety regulations and effectively responding to emergencies at airports.
