A Captain’s Guide to Safely Handle Fire on Boats

The sun is shining; the water is calm. It’s another perfect day on your boat.

Then, you smell smoke.

Fire on boats is hazardous, requiring immediate and decisive action to ensure everyone’s safety.

Learning about boat fire safety prepares you for this type of emergency. Here, we outline exactly how to handle a fire on a boat.

What to Do When You Encounter a Fire on Your Boat

Keeping your passengers safe must always be your first priority. Fiberglass, wood, and other materials are burnable, meaning your entire boat is fuel for the flames. Take control of the situation right away to mitigate risk:

Sound the Alarm

If you’re on a small boat, quickly alert all crew and passengers without causing panic.

If your boat has an alarm system, activate it. Always sound the alarm before fighting the fire. Otherwise, no one else will know about the danger if you’re injured or incapacitated.

Cease Operation

Safely slow down and stop the boat. Moving can fan the flames and accelerate their spread depending on where the fire is. Movement also pushes smoke around the vessel, further endangering passengers.

Cut Fuel Supply

Immediately shut off the boat’s fuel supply if you can. Doing so will reduce the fire’s escalation risk and keep you and your passengers safer long enough to put out the fire or get help.

Common Causes of Fire on Boats

Preventing issues like boat fires is key to maintaining safety on the water. With keen awareness and the proper precautionary measures, you’ll recognize the common causes and early warning signs of fires.

Pay close attention to the threats associated with:

• Electrical faults: Faulty wiring and overloaded circuits are significant risks — often compounded by amateur electrical work. Many boaters perform essential electrical maintenance independently, but without professional experience, they use equipment that isn’t marine grade. Outlets and circuits that work great at home will easily fail in salty, wet environments.
• Fuel leaks: A faulty clamp, broken connection, or cracked fuel line leads to dangerous leaks and, eventually, fires. Damaging UV rays also dry out hoses and contribute to equipment failure.
• Engine issues: Overheating is the primary cause of engine fires, among other issues.
• Galley accidents: Grease fires and other cooking incidents are a problem in the confined galley on most boats.
• Improper storage of flammable materials: Certain combustible materials can ignite independently without a stray spark. If you can’t discard oily rags and other dangerous items off your boat, keep them in a container that prevents spontaneous combustion.
• Careless smoking: Too many people who smoke on boats aren’t worried enough about fuel or flammable materials. Never smoke while fueling, and always stomp out the butts.

Don’t let fires catch you off guard. Early warning signs include the smell of burning wood and electronics, electrical failures such as flickering lights, and engine performance issues. Experienced boaters often hear, smell, or see indications of a problem before the flames erupt.

As you look out for these warning signs, remember that engine compartments and cabins are at a higher risk of fire because of fuel, electrical systems, appliances, and electronics.

Methods for Managing Boat Fires Safely

If a fire breaks out, don’t panic! Specific tools and methods can help you mitigate damage.

Fire Extinguishers

The Coast Guard requires most recreational boats to carry an ABC fire extinguisher, which provides versatile protection for three fire classifications:

A: Ash-creating fires (such as paper)

B: Oil fires

C: Electrical fires

ABC fire extinguishers offer several key benefits, including:

• Broad coverage and versatility: Effective against combustibles, flammable liquids, and electrical fires onboard.
• Compactness: Conserves space and reduces costs because you don’t need three fire extinguishers for three different types of fires.
• Ease of use: Simple operation improves emergency response and makes training easier.
• Low maintenance: Streamlines inspections and upkeep, ensuring you’re ready for any fire emergency.

Considerations

Proper use of a fire extinguisher is essential. Extinguishers leave behind a powdery residue that can damage equipment and ruin electronics, so avoid spraying an object to prevent it from catching fire.

Monitor and maintain your fire extinguishers to guarantee they operate when it matters most. Ensure your extinguishers are properly tagged and give them a monthly visual inspection.

Boat Positioning

Let nature help fight your boat fire by harnessing wind to your advantage. Position your boat so the wind directs flames and smoke away from passengers and unburned areas. Repositioning slows the spread of the fire, improves visibility, and reduces smoke inhalation.

When to Evacuate a Boat on Fire

Despite your best efforts, a fire can become uncontrollable. Still, many boaters abandon their vessel too soon. 

Staying on your boat is almost always safer than risking the water. Only evacuate when:

1. You can’t control or contain the fire.
2. Toxic smoke or high heat levels endanger lives.
3. Fuel presents an explosion risk.

If you need to evacuate your boat, don’t enter a situation as dangerous as the one you’re leaving. Abandon the ship safely by following this quick evacuation guide:

• Signal for help: Use your VHF radio to make a mayday call with key details about your situation, including your location.
• Activate GPS: Your emergency position indicating radio beacon (EPIRB) can help the Coast Guard find you, especially if you’re not within sight of land.
• Bring essentials: If you can safely do so, grab an emergency kit called a ditch bag.
• Evacuate: Guide everyone safely to available life rafts.
• Wear life jackets: Ensure all passengers wear an appropriate life jacket.
• Stay together: Don’t split from your group or try to swim alone. Rescuing a group of people huddled together is always easier than finding individuals. Keep the group visible and wait for rescue.
• Use flares: Wait until rescue is nearby before using your flares. They won’t do you any good if no one sees them.

Prevent Fire on Boats

The best strategy for fighting fires is to avoid them in the first place. Performing essential maintenance and safety checks minimizes the risk of fire on boats. 

Be sure to:

1. Check electrical fuel systems.
2. Clean engine areas.
3. Store flammable materials safely.
4. Keep exits clear.
5. Learn how to use a fire extinguisher.
6. Conduct regular safety drills.
7. Teach boat fire safety to passengers.

Finally, double-check your emergency kit to ensure it contains essential survival items, such as:

• Life jackets
• Flares
• EPIRB/PLB
• Fire extinguishers
• VHF radio with DSC
• Flashlight and batteries
• First aid kit
• Emergency food and water
• Survival suits for cold water
• Navigation tools
• Life raft for offshore boating
• Water pump or bailer
