Before fueling a vessel, what should you do?

• A. Turn anything off that might cause a spark... Close all doors, windows, and other openings to prevent fumes from entering
• B. Light a match
• C. Open all compartments
• D. Start the engine

Answer: (A)

Eliminating ignition sources and venting vapors is essential before fueling. Fuel vapors can ignite from even a small spark, so turning off the engine and other potential sources of ignition removes those triggers. Closing doors, windows, and other openings helps keep fumes from entering the boat’s compartments, reducing the chance of vapor buildup in enclosed spaces. Lighting a match, opening compartments, or starting the engine would introduce flames or sparks or increase vapor presence, creating a fire or explosion risk. Always fuel in a well-ventilated area, avoid smoking, and ground the fueling nozzle to prevent static discharge.
