A small fuel spillage has occurred during helicopter refueling. After the leak has been stopped and fire-control personnel have been notified and are standing by, the next step is to __________.

Correct Answer: Option C — wash spilled fuel away with a flood of water

Helicopter refueling safety protocols dictate that spilled fuel must be washed away with water to dilute the flammable liquid and prevent ignition. Using rags is insufficient for larger spills and risks static discharge or leaving flammable residues, whereas a flood of water effectively clears the deck surface.
