What immediate action is advised when a boat fire starts, to prevent fuel from feeding the fire?

• A. Cut fuel sources and use fire extinguisher
• B. Shut off all electronics
• C. Jettison cargo
• D. Open all hatches

Answer: (A)

When a boat fire starts, the priority is to starve the flames by cutting off the fuel supply. This means shutting off the engine’s fuel valve or pump so no more fuel can feed the fire. Once the fuel feed is stopped, you can use a fire extinguisher to knock down the existing flames more effectively and reduce the chance of re-ignition.

Open hatches, jettison cargo, or leaving electronics on won’t stop the fuel from feeding the fire and can even make things worse by increasing oxygen or hazards. Shutting off power is a safety step, but the crucial action to prevent the fire from growing is to cut the fuel source and then apply the extinguisher.
