Final answer:
A good safety procedure when fueling your vessel is to keep the fuel nozzle in contact with the fuel opening to prevent static electricity discharge and fuel spills.
Step-by-step explanation:
- Smoking near the fueling area: This is not a good safety procedure as smoking poses a fire hazard and can ignite the fuel vapors.
- Using a cell phone while fueling: It is not recommended to use a cell phone while fueling due to the potential risk of sparking and causing an explosion.
- Keeping the fuel nozzle in contact with the fuel opening: This is a good safety procedure as it minimizes the risk of static electricity discharge and prevents fuel spills.
- Standing on the fuel nozzle while fueling: This is not a good safety procedure as it can damage the fueling equipment and potentially cause fuel leaks.
