Question 1124 Deck Safety

The correct answer is A) ventilate before starting engine. After fueling a gasoline-powered vessel, it is crucial to ventilate the vessel thoroughly before starting the engine. This is because gasoline vapors can accumulate in the bilge and other enclosed spaces, creating a highly flammable and explosive environment. Proper ventilation helps to remove these vapors and ensure a safe restart of the engine. The other options are incorrect as they do not address the need for proper ventilation, which is a critical safety step after refueling a gasoline-powered vessel.
