What is the minimum flow rate for ARFF handlines according to NFPA 403?

• A. 50 gpm
• B. 80 gpm
• C. 100 gpm
• D. 120 gpm

Answer: (B)

The correct flow rate for ARFF (Aircraft Rescue and Fire Fighting) handlines according to NFPA 403 is 80 gallons per minute (gpm). This standard is established to ensure effective firefighting operations in the unique environment of an airport, where the types of fires that may occur, particularly involving aircraft and fuel, require a substantial volume of water for control and suppression.

Using 80 gpm for handlines strikes a balance between the need for sufficient water volume to tackle potential aircraft fires and the operational considerations of firefighter safety and mobility. This flow rate is designed to deliver an adequate amount of water to fight various types of fires common in aviation incidents, considering the quick response needed in emergency scenarios.

Understanding the minimum flow rate is critical for firefighters as it helps them prepare and equip their handlines appropriately, ensuring they can deliver the necessary water volume effectively during an emergency. This allows for a swift and efficient firefighting response, ultimately protecting lives and property.
