Marine fires are among the most serious emergencies that can occur onboard a vessel. A fire can spread rapidly through enclosed spaces, machinery areas, accommodation zones or cargo spaces, putting crew, passengers, cargo and the vessel itself at significant risk.
The International Maritime Organization (IMO) addresses fire prevention, detection, containment and extinction through SOLAS Chapter II-2, which includes requirements covering fire protection, detection, firefighting systems and safe means of escape.
Understanding the common causes of marine fires and taking preventive measures with the support of a DM Safety marine fire and safety supplier can significantly reduce the risk of fire-related incidents.
Common Causes of Marine Fires
1. Fuel and Oil Leaks
Fuel oil, lubricating oil and hydraulic fluids can become highly dangerous when they come into contact with hot machinery surfaces, exhaust components or other ignition sources.
Leaks may occur because of damaged hoses, loose connections, deteriorated seals or inadequate maintenance.
How to prevent them:
- Inspect fuel and oil lines regularly.
- Replace damaged hoses, seals and fittings promptly.
- Keep machinery spaces clean and free from oil accumulation.
- Repair leaks as soon as they are identified.
- Keep combustible liquids away from hot surfaces.
- Maintain appropriate insulation around hot machinery and exhaust systems.
2. Electrical Faults
Electrical equipment is another major source of fire risk onboard vessels. Overloaded circuits, damaged cables, loose connections, short circuits and poorly maintained electrical panels can generate excessive heat or sparks.
How to prevent them:
- Inspect electrical systems regularly.
- Replace damaged cables and electrical components.
- Avoid overloading circuits.
- Keep electrical panels clean and dry.
- Ensure electrical installations are properly maintained.
- Use equipment suitable for the marine environment.
Early detection is particularly important because SOLAS Chapter II-2 emphasizes detecting a fire in its space of origin and providing alarms to support firefighting and safe escape.
3. Engine Room Fires
Engine rooms contain several potential ignition sources, including engines, generators, fuel systems, exhaust pipes and other machinery. A combination of fuel or oil leaks and high-temperature surfaces can create a serious fire hazard.
Prevention measures include:
- Conducting regular engine-room inspections.
- Maintaining engines and generators according to manufacturer requirements.
- Checking fuel and lubrication systems for leaks.
- Keeping exhaust systems properly insulated.
- Removing oil-soaked materials and accumulated residues.
- Ensuring fixed fire suppression systems are operational.
- Keeping portable fire extinguishers accessible.
4. Galley and Cooking Fires
Cooking equipment, hot oil and grease can create significant fire risks in vessel galleys. Unattended cooking equipment and poor cleaning practices can allow a small fire to develop rapidly.
How to prevent galley fires:
- Keep cooking areas clean.
- Regularly clean grease and oil deposits.
- Never leave cooking equipment unattended.
- Inspect cooking appliances and electrical connections.
- Keep suitable fire extinguishing equipment readily available.
- Train crew members in emergency response procedures.
SOLAS requirements also address fire protection for cooking equipment, including specific arrangements for deep-fat cooking equipment on applicable vessels.
5. Hot Work
Welding, cutting, grinding and other hot-work activities can produce sparks and high temperatures capable of igniting nearby combustible materials.
Hot work is particularly hazardous when carried out near fuel tanks, pipelines, insulation, paint, cargo or other flammable materials.
How to prevent hot-work fires:
- Use a formal hot-work permit system.
- Inspect the work area before starting.
- Remove combustible materials from the area.
- Use fire-resistant screens and protective coverings.
- Assign a trained fire watch where required.
- Keep suitable firefighting equipment nearby.
- Inspect the area after the work has finished to identify hidden smouldering materials.
6. Improper Storage of Flammable Materials
Paints, solvents, chemicals, fuel-related products, cleaning agents and other combustible materials can increase fire risk when stored incorrectly.
Prevention measures:
- Store flammable materials in designated areas.
- Keep containers properly closed and labelled.
- Separate incompatible substances.
- Maintain adequate ventilation where required.
- Keep storage areas away from ignition sources.
- Follow applicable vessel procedures and safety requirements.
7. Smoking and Open Flames
Carelessly discarded cigarettes, unauthorized smoking and uncontrolled open flames can ignite combustible materials.
Prevention measures include:
- Enforcing designated smoking areas and vessel policies.
- Prohibiting smoking in restricted areas.
- Properly disposing of cigarette materials.
- Controlling the use of open flames.
- Clearly displaying appropriate warning signs.
8. Poor Housekeeping
Accumulated oil, grease, waste, combustible materials, rags and packaging can provide fuel for a fire.
Good housekeeping is therefore an important part of marine fire prevention.
Crew should routinely inspect machinery spaces, workshops, galleys, storage rooms and accommodation areas and remove unnecessary combustible materials.
How to Prevent Marine Fires
Fire prevention should not depend on firefighting equipment alone. A comprehensive approach should combine maintenance, inspections, fire detection, firefighting systems, crew training and emergency procedures.
Regular Inspection and Maintenance
Routine inspection helps identify potential hazards before they become emergencies. Fire detection systems, alarms, extinguishers, fire pumps, hoses, fixed suppression systems and other equipment should be maintained and tested according to applicable requirements and vessel procedures.
IMO’s SOLAS Chapter II-2 includes operational requirements for maintaining the effectiveness and readiness of fire safety measures onboard.
Maintain Fire Detection and Alarm Systems
Early detection can give crew valuable time to respond before a fire spreads.
Depending on the vessel and applicable requirements, fire safety arrangements can include fire detection and alarm systems, smoke detection, fire extinguishers, fixed gas systems, foam systems, water-spraying or water-mist systems and other firefighting arrangements. The IMO’s Fire Safety Systems (FSS) Code provides technical specifications for fire safety systems required under SOLAS Chapter II-2.
Keep Firefighting Equipment Ready
Fire extinguishers, fire hoses, fire pumps and fixed firefighting systems must be accessible, properly maintained and ready for immediate use. Crew members should be familiar with the location and operation of all firefighting equipment onboard.
They should also understand which type of extinguisher is suitable for different classes of fire, how to activate fire alarms, how to report an emergency, and where the designated escape routes and muster stations are located. Regular familiarization with this equipment can help crew members respond quickly and effectively during a fire.
Conduct Fire Drills and Training
Having firefighting equipment onboard is not enough if crew members are not properly trained to use it. Regular fire drills and safety training help crew understand their responsibilities and develop the skills needed to respond during an emergency.
Training should cover fire detection, alarm activation, initial firefighting procedures, emergency communication, evacuation and muster procedures. Regular drills can also help identify weaknesses in emergency response plans and improve crew preparedness.
Control Ignition Sources
Reducing potential ignition sources is an important part of marine fire prevention. Vessel operators should maintain strict controls over hot work, smoking, open flames, electrical equipment and galley appliances.
Hot machinery surfaces, sparks and overheating equipment should also be monitored and properly managed. Controlling these sources, combined with regular inspections and maintenance, can significantly reduce the likelihood of a fire starting onboard.
Marine Fire Safety Equipment
A vessel’s fire safety arrangements depend on its type, size, operation and applicable maritime safety requirements. Fire protection equipment may include portable fire extinguishers, fire hoses and nozzles, fire hydrants, fire pumps, fire detection and alarm systems, smoke detectors, fixed fire suppression systems, water-mist systems, foam firefighting systems and fixed gas fire-extinguishing systems.
Fireman’s outfits and appropriate personal protective equipment are also important for crew members involved in firefighting operations, while emergency lighting and clearly maintained escape arrangements support safe evacuation.
The International Maritime Organization’s (IMO) Fire Safety Systems (FSS) Code provides technical requirements for various fire safety systems and equipment used onboard ships. These include portable fire extinguishers, fixed gas and foam fire-extinguishing systems, water-spraying and water-mist systems, automatic sprinkler and fire detection systems, emergency fire pumps and other fire protection arrangements.
Ensuring these systems are properly installed, inspected, maintained and ready for use is an essential part of effective marine fire safety.
