The importance of ventilation is crucial. The purpose of ventilation systems is to avoid explosions by removing flammable gases that can accumulate in the bottom of the vessel. Properly installed ventilation systems greatly reduce the chance of a life-threatening explosion.
- All vessels with gas-powered engines and constructed in a way that would entrap fumes, must have at least two ventilation ducts fitted with cowls to remove the fumes. On Utah waters, any efficient natural or mechanical ventilation system capable of removing entrapped fumes will meet this requirement.
- If your vessel is equipped with a power ventilation system, turn it on for at least four minutes after fueling, prior to starting your engine.
- If your vessel is not equipped with a power ventilation system (such as personal watercraft), open the engine compartment and sniff for gasoline fumes before starting the engine.
Federal law requires that vessels built after July 31, 1980, which contain power exhaust blowers in gasoline engine compartments, must have the above warning sticker placed near the instrument panel.
