Preventing Electrical Fires On Boats: What You Need To Know

what to do electrical fire on boat

Boat fires are a serious concern for boat owners and can be caused by a number of factors, including engine malfunctions, galley fires, and insufficient ventilation of enclosed engine compartments. Electrical fires are especially difficult to extinguish, and they often occur due to old components or improper maintenance. To prevent electrical fires, it is important to regularly inspect and maintain the boat's electrical system, including shore power cords, batteries, and wiring. In the event of an electrical fire, it is crucial to act quickly to ensure the safety of everyone on board. This includes stopping the engine, positioning the boat to minimise the spread of fire, shutting off gas and electrical systems, and using a marine-rated fire extinguisher. Knowing the location of shut-off valves and having a fire safety plan in place are also important aspects of fire preparedness.

Stop the engine and disconnect the gas tank

If a fire breaks out on your boat, it is important to act quickly to curb the fire and save lives. As the boat operator, it is your responsibility to take the lead.

Firstly, stop the engine. This is especially important if the source of the fire is the engine itself, as turning off the engine will reduce the chances of the fire spreading or causing an explosion. If the fire has spread throughout the boat, however, and you are unable to turn off the engine, evacuate immediately.

Next, change the positioning of your boat so that the wind blows the fire away from the boat. This will help to minimize its spread and reduce smoke inhalation.

After that, shut off the gas to the engine and disconnect the gas tank if it is safe to do so. Remove any additional fuel sources, such as fuel, oil, or gas fumes, which can burn in the engine room.

It is also crucial to notify the Coast Guard using VHF Channel 16. Letting someone know you are in trouble will enable rescue agencies or good Samaritans nearby to respond quickly if assistance is needed.

Position the boat to minimise fire spread

Positioning the boat correctly is a crucial step in containing an electrical fire and minimising its spread. If the fire is at the back of the boat, near the engine, the boat should be positioned so that the wind blows the fire away from the boat. This will help to prevent the fire from spreading and minimise smoke inhalation.

If you are on a small boat, use oars to point the front of the boat in the direction of the wind. This should only be done if the fire is at the back of the vessel. If the fire is in the front of the boat, point the stern in the direction of the wind. This will stop the fire from growing or spreading to other areas of the boat.

Even if the engine is cut off, you may still be able to steer the boat to change its position so that the fire does not worsen and remains contained at the back of the boat.

In the event of an electrical fire, it is important to act quickly and follow the necessary steps to curb the fire and save lives. Advise all passengers to put on personal flotation devices immediately and, if possible, use a fire extinguisher to mitigate the damage. If you cannot control the fire, promptly evacuate the vessel.

Use a marine fire extinguisher

If a fire breaks out on your boat, it is important to act quickly to curb the fire and save lives. You should start by stopping the engine and positioning the boat so that the wind blows the fire away from the boat. Remove any additional fuel sources and shut off the gas to the engine. If possible, disconnect the gas tank.

If you have a fire extinguisher on board, it is good practice to keep it away from the back of the boat where the engine is. That way, if there is a fire in the back of your boat, you can access the fire extinguisher safely. Marine-rated Class B fire extinguishers are the class required on most boats, as gasoline fires are the most common type of boat fire. However, a Class ABC fire extinguisher, which can handle all fires, is the most recommended.

When using a marine fire extinguisher, aim for the base of the fire. Pull the pin and squeeze the handle, moving the extinguisher in sweeping motions from side to side, up the flames until they are extinguished. Continue using it until the fire is completely out.

If you cannot control the fire yourself, promptly evacuate the vessel. Advise all passengers to put on personal flotation devices immediately. Before evacuating, radio or call for assistance from emergency response personnel.

Evacuate if necessary

If you cannot control the fire yourself, it may be time to evacuate the vessel. Before evacuating, radio or call for assistance from emergency response personnel. If you are on a small boat, use oars to point the front of the boat in the direction of the wind. If the fire is in the front of the boat, point the stern in the direction of the wind. This should stop the fire from growing or spreading to other areas of the boat. Make sure all passengers put on personal flotation devices immediately. If the fire has spread throughout the boat, and you cannot turn off the engine, evacuate.

If you are injured in any capacity, contact a lawyer immediately. Inform the necessary law enforcement agencies of the incident. If you are unable to return to the dock under the boat's power, call for help, especially if there are any injuries on board.

To prevent fires, ensure that all connections are tight, and that wiring is supported and secured to minimize the impact of vibration. Keep battery terminals clean, and inspect wiring for signs of chafe. Inspect shore power cords, and replace them if there is any sign of wear. Never use an electric heater when no one is aboard.

Regular electrical maintenance

To prevent electrical fires on a boat, regular electrical maintenance is key. The DC electrical system—including batteries, lights, and wiring—is the most common cause of fires on boats, so it's important to inspect these components regularly. Here are some detailed steps to include in your regular electrical maintenance routine:

Monthly Maintenance:

  • Inspect all electrical connections associated with the engine-starting and charging systems. This includes connections from the batteries to the starter and the alternator.
  • Tighten any loose connections and replace corroded wire ends and terminals.
  • Keep battery terminals clean.
  • Secure and support all wiring to minimize the impact of vibration and protect against chafing. Ensure wiring is properly supported away from hot surfaces, especially in the engine room.
  • Inspect shore power cords for any signs of wear or corrosion and replace them if necessary.
  • Check battery switches and replace them if they are more than 15 years old.
  • Inspect battery wiring, switches, and terminals at least once a month during the boating season.

Other Maintenance Tasks:

  • Never use an automotive battery charger instead of a marine battery charger. Automotive chargers can overcharge batteries and start a fire.
  • Ensure you have the mandatory firefighting equipment on board, including a marine-rated Class B fire extinguisher.
  • Inspect your fire extinguisher monthly to ensure it is ready for use. Check the gauge to ensure it is fully charged, inspect the seals and hose for any damage, and weigh dry chemical extinguishers to meet the minimum weight.
  • If your boat has a galley, ensure anyone using it knows how to do so safely.

Remember, regular maintenance and inspections can help prevent electrical fires on your boat. It is also important to understand how to operate and maintain your boat's engine and electrical system.
