What is the minimum water supply required on an ARFF apparatus?

The minimum water supply required on an Aircraft Rescue and Firefighting (ARFF) apparatus is established to ensure that firefighters can effectively combat aircraft fires during emergencies. In the context of ARFF operations, a water supply of 1,500 gallons is typically necessary because it aligns with the guidelines provided by organizations such as the National Fire Protection Association (NFPA) and other regulatory bodies.

This volume is considered essential to handle various types of incidents, particularly the intense fires that can occur with aviation fuels. The 1,500-gallon minimum enables a sustained attack on fires, providing a reliable source of water to cool the aircraft, suppress flames, and protect any potential victims. A greater capacity is often desired for larger ARFF vehicles or in response to larger aircraft, but the baseline requirement focuses on ensuring that there is enough water to initiate an effective firefighting response.

In summary, 1,500 gallons is recognized as the minimum standard to support ARFF operations effectively. This standard is crucial for maintaining safety and preparedness in airport firefighting scenarios.
