What safety precautions should be taken when refueling aircraft?

The correct choice emphasizes the importance of safety measures that are critical when refueling aircraft. Using appropriate equipment is essential to ensure that the refueling process is conducted safely and efficiently. This includes using fuel hoses and nozzles that are specifically designed for aviation fuel to prevent leaks and spills.

Wearing personal protective equipment (PPE) is vital in protecting yourself from potential hazards, which may include exposure to harmful fuel vapors. PPE, such as gloves and goggles, helps minimize the risk of injury.

Handling flammable materials safely is a primary concern when refueling. This involves following proper protocols to prevent ignition sources from coming into contact with fuel vapors, ensuring that the area is well-ventilated, and avoiding any actions that could create sparks or flames.

In contrast, performing refueling at night may increase risks, as visibility is reduced and hazards are harder to identify. Refueling only in open areas away from crops could be prudent, but it doesn't address the more critical aspects of using appropriate equipment and PPE. Refueling without shutting down the engine can significantly elevate risks, as operating engines can produce sparks or heat, creating a dangerous situation if flammable vapors are present.
