🔍 Key Concepts

• Gasoline vapor hazards in enclosed spaces and bilges • Correct post-fueling ventilation procedures on small vessels • What actions might increase vs reduce the risk of explosion or fire

💭 Think About

• Look at each option and ask: does this action make it safer or more dangerous if gasoline fumes are present? • Which choice focuses on removing or dispersing any fuel vapors that may have collected during fueling? • Which options would actually introduce fuel or allow vapors to accumulate where an ignition source could be present?

✅ Before You Answer

• Identify which choice clearly improves ventilation in enclosed compartments after fueling • Eliminate any choice that involves adding fuel to the bilge or leaving tank openings uncapped • Think about USCG guidance: before starting the engine, the boat should be thoroughly ventilated and checked for fumes
