What is an important action to ensure safety while fueling your vessel?

Filling the tank slowly is crucial for safety while fueling your vessel. This practice minimizes the risk of spills and allows for proper ventilation of gasoline vapors, which can be highly flammable and pose a fire hazard. By taking your time, you can also monitor the fuel level more closely, preventing overfilling and ensuring that no fuel escapes into the environment.

Using an electronic device could create a spark, which is dangerous around flammable materials. Filling the tank quickly can lead to fuel spills and hazardous situations. Additionally, leaving the engine running increases the likelihood of igniting fuel vapors, making it critical to ensure the engine is turned off before beginning the refueling process.
