According to NFPA 403, what dimensions are defined to ensure timely ARFF response?

• A. 1,000 ft each side of runway
• B. 500 ft each side of runway and 3,300 ft beyond each end
• C. 1,500 ft each side of runway and 5,000 ft beyond each end
• D. 750 ft each side of runway

Answer: (B)

The correct answer emphasizes the dimensional requirements set forth in NFPA 403 to ensure timely Aircraft Rescue and Firefighting (ARFF) response. According to the NFPA 403 standards, having a width of 500 feet each side of the runway and extending 3,300 feet beyond each end of the runway is critical for maintaining an effective emergency response zone.

This dimension allows for a clear and accessible area in which emergency responders can operate efficiently in the event of an incident, minimizing potential delays and ensuring rapid access to the scene. The standards recognize the need for sufficient space to accommodate firefighting apparatus, personnel, and the safe navigation of aircraft during emergencies.

In contrast, the other choices suggest either narrower widths or shorter distances beyond the runway, which do not align with the NFPA’s requirements for optimal ARFF readiness. Adequate space is vital for strategic positioning of fire suppression equipment and for safe maneuvering in emergency situations. The specifications outlined in option B reflect a careful consideration of these factors, facilitating a comprehensive approach to airport firefighting and rescue operations.
