Which of the following actions is the best to take when fueling an outboard boat with a portable tank?

The best action to take when fueling an outboard boat with a portable tank is to place the tank on the dock or on shore to fill it. This approach minimizes the risk of spills and fire hazards. When the tank is on land, it is easier to control the fueling process, ensuring that any potential fuel leaks or splashes are contained. Additionally, filling a portable tank while it is on the boat can increase the risk of static electricity buildup and accidental fuel spills onto the vessel, which can be hazardous in an enclosed space.

Moreover, filling the tank in an enclosed area is strongly discouraged, as it can lead to the accumulation of flammable vapors. Using an electric pump can also pose risks if not specifically designed for fuel transfer, particularly concerning safety standards and potential electrical hazards. By opting to fill the tank on a stable, non-moving surface like the dock or shore, safety is greatly enhanced, reducing the possibility of accidents during fueling.
