The purpose of ventilation systems is to avoid explosions by removing flammable gases. Properly installed ventilation systems greatly reduce the chance of a life-threatening explosion.
All gasoline-powered vessels, constructed in a way that would entrap fumes, must have at least two ventilation ducts fitted with cowls to remove the fumes.
If your vessel is equipped with a power ventilation system, turn it on for at least four minutes both after fueling and before starting your engine.
If your vessel is not equipped with a power ventilation system (for example, a PWC), open the engine compartment and sniff for gasoline fumes before starting the engine.
