Which of the following is considered a safe practice during refueling?

Closing all hatches and doors while refueling is considered a safe practice because it helps prevent flammable vapors from entering the interior of the boat. By securing openings, you reduce the risk of ignition sources coming into contact with fuel vapors, which is essential for maintaining safety during the refueling process.

It's important to keep the area around the fuel source clear of potential hazards. Ensuring a safe environment minimizes the risk of fire or explosions, which are significant dangers associated with boating. This practice also aligns with general safety protocols that encourage creating a controlled environment free from ignition.

In contrast, the practices of running the engine, refueling while the boat is in motion, or ignoring the fuel gauge can introduce numerous safety risks, such as engine sparks igniting vapors or the potential for losing control of the vessel. Therefore, securing the boat’s hatches and doors is a vital practice during refueling that supports the overall safety of the boating activity.
