• A. 50 ft
• B. 100 ft
• C. 150 ft
• D. 200 ft

Answer: (B)

The maximum operating distance for portable ABC extinguishers from aircraft fueling is set at 100 feet. This distance is established based on various safety standards and guidelines that ensure the effectiveness of fire suppression efforts while minimizing the risk to personnel and the surrounding area.

When aircraft are being fueled, there is an inherent risk of fire due to the flammable nature of aviation fuel. Having extinguishers within 100 feet allows for quick response and efficient intervention in the event of a fire, while still maintaining a safe distance from potential ignition sources. This balance is crucial in ensuring the safety of both the firefighters and the aircraft during fueling operations.

Other distances, either shorter or longer, do not align with standard safety protocols that prioritize both accessibility to fire-fighting equipment and the safety of individuals working in proximity to fueling operations. Therefore, the 100-foot guideline is critical in ensuring effective and safe response capabilities during these high-risk scenarios.
