During aircraft refueling, which condition may create a fire hazard?

• A. Dry weather
• B. Dripping, splashing, or overflow of fuel
• C. Cleaning nearby
• D. Aircraft parked away

Answer: (B)

Flammable aviation fuel can ignite if it is not contained. Dripping, splashing, or overflow of fuel creates the fire hazard because it spreads fuel to surfaces, hoses, and equipment that may have ignition sources such as hot components, electrical circuitry, or static discharge points. The fuel can also vaporize and form ignitable vapors that linger near the ground and travel to any ignition source, increasing the chance of a flame or spark starting a fire. Other scenarios are less direct. Dry weather doesn’t in itself create a leak, cleaning nearby doesn’t inherently introduce an ignition source in the context of a fuel spill, and aircraft parked away reduces exposure to fuel leaks. The key risk is any actual or potential fuel release spilling onto the area.
