What is the minimum distance between refueling GSE and aircraft or building?

• A. 10 meters
• B. 20 meters
• C. 5 meters
• D. 15 meters

Answer: (D)

Fueling involves flammable liquid and vapors, so a safe buffer between the fueling equipment and the aircraft or any nearby building is essential. A 15-meter clearance creates space to safely connect and operate hoses, keeps fumes and spills from reaching sensitive areas like aircraft surfaces, doors, vents, or ventilation intakes, and provides room for emergency actions if something goes wrong. This distance also reduces the chance that a spill or vapor could come into contact with ignition sources or people nearby, and it allows the operator to move freely if adjustments are needed. Distances smaller than this raise the risk of fire or exposure, while a larger gap isn’t necessary for standard fueling operations and would slow things down.
