What is the minimum amount of water that Class II ARFF vehicles must carry for foam production?

• A. 100 gallons
• B. 250 gallons
• C. 500 gallons
• D. 750 gallons

Answer: (C)

The minimum amount of water that Class II ARFF (Aircraft Rescue and Fire Fighting) vehicles must carry for foam production is 500 gallons. This requirement is set to ensure that these vehicles are adequately equipped to handle fire incidents involving aircraft and to effectively produce foam, which is essential for suppressing fuel fires. The capacity ensures enough water is available to create an effective foam blanket, which helps smother and cool down the flames.

The specification for 500 gallons balances the need for mobility, operational efficiency, and sufficient resources to combat potential fire scenarios at airports. It allows personnel to deploy foam rapidly and effectively without the prolonged exposure to hazards that might happen with inadequate water supplies. This quantity is a standard used to ensure safety and effectiveness in emergency responses specifically tailored for firefighting operations at airports.
