What should you do before starting an inboard engine after fueling?
Answer: Run the bilge blower for at least 4 minutes to clear gasoline vapors
Running the bilge blower for at least 4 minutes removes potentially explosive gasoline vapors from the engine compartment before any ignition source is introduced.
How long should the bilge blower run before starting an inboard engine after fueling?
Answer: At least 4 minutes
The U.S. Coast Guard recommends running the bilge blower for a minimum of 4 minutes to thoroughly flush gasoline vapors from enclosed engine spaces.
Where should portable fuel tanks be filled?
Answer: On the dock or shore, away from the boat
Portable fuel tanks should be removed from the boat and filled on the dock or ashore to keep fuel vapors and potential spills away from the vessel.
What should passengers do while a boat is being fueled?
Answer: Go ashore or move well away from the fueling area
All passengers should leave the boat and move away from the fueling area so that fewer people are at risk if a fire or explosion occurs during fueling.
Which fire extinguisher class is rated for flammable liquid fires such as gasoline?
Answer: Class B
Class B extinguishers are designed for flammable liquid fires — including gasoline, oil, and grease — which represent the most common fire hazard on recreational boats.
What should you do if you detect gasoline fumes in the bilge before starting the engine?
Answer: Open hatches and run the blower until the fumes are gone
Gasoline vapor must be fully ventilated by opening hatches and running the bilge blower until the smell disappears before any spark-producing action such as starting the engine.
Why should you keep the fuel nozzle in contact with the fill pipe during boat fueling?
Answer: To prevent static electricity sparks that could ignite vapors
Maintaining metal-to-metal contact between the nozzle and fill pipe grounds the connection and prevents static electricity buildup that could generate a spark near fuel vapors.
