What is one safety measure to take when filling a boat's fuel tank?

Filling the tank slowly is an important safety measure because it helps prevent spills and reduces the risk of static electricity buildup, which can ignite fuel vapors. When fuel is poured too quickly, it can generate friction, creating static sparks that could potentially ignite flammable vapors. Additionally, a slow filling process allows for better monitoring of the tank's capacity and minimizes the risk of overfilling, which can lead to spillage and environmental hazards.

This approach aligns with best practices for safe fueling, emphasizing caution to protect both the individual performing the task and the surrounding environment. Filling gradually ensures precision and control, which are crucial in maintaining safety during the fueling process.
