Understanding the Fire Safety Systems (FSS) Code on Ships
Fires on ships pose a serious risk, potentially causing catastrophic damage, endangering lives, and threatening the safety of the ship. To mitigate these risks, ships are equipped with fire safety systems, including alarms, fire extinguishers, and emergency response plans, that comply with international regulations such as the Fire Safety Systems (FSS) Code. Proper training and regular maintenance are essential for preventing and effectively managing shipboard fires.
The Fire Safety Systems (FSS) Code is a fundamental element of maritime safety, providing comprehensive guidance on fire prevention, detection, and extinguishing systems on board ships. Implemented under the International Convention for the Safety of Life at Sea (SOLAS), the Code is crucial for ensuring the safety of ships, crews, and cargo. This article aims to provide students of maritime studies with a deeper understanding of the FSS Code, its importance, and its detailed application on ships.
Overview of the FSS Code
The FSS Code was first adopted by the International Maritime Organization (IMO) in 2000 and has been regularly updated to incorporate the latest developments in fire safety technology and lessons learned from maritime incidents. The Code sets out requirements for shipboard fire safety systems and equipment, including:
- Main fire-fighting systems,
- Fixed fire-fighting systems,
- Fire detection and alarm systems,
- Smoke and ventilation systems,
- Escape routes,
- Firefighters’ equipment,
Each chapter of the Fire Safety Code details the specific requirements for these systems to ensure they are capable of responding to various fire scenarios on board.
Main Components of the Fire Safety Code
1. Main Fire-Fighting Systems
Main fire-fighting systems are the backbone of a ship’s firefighting capabilities, providing a reliable source of water for firefighting throughout the ship. The Fire Safety Code regulates the design, installation, and maintenance of these systems to ensure their continued operation and effectiveness.
Design and Construction: The main fire-fighting system must be capable of delivering sufficient water at appropriate pressure to multiple fire hydrants simultaneously. This system typically consists of a seawater inlet, fire pumps, and a network of pipes and fire hydrants strategically located around the ship.
Fire Pumps: The ship must be equipped with at least two independently operated fire pumps. These pumps must be capable of delivering water to any fire hydrant at a pressure of at least 0.27 N/mm².
Fire Hydrants and Hoses: Fire hydrants must be distributed so that at least two streams of water reach every part of the ship from different hydrants. Fire hoses must be made of durable material, be long enough to cover the necessary area, and be equipped with nozzles capable of discharging both solid and spray streams.
Maintenance and Testing: Regular maintenance and testing are required to ensure the proper functioning of the main fire-fighting system. This includes checking for leaks, checking the operation of the pumps, and ensuring that the hoses and nozzles are in good condition.

2. Fixed Fire-Fighting Systems
Fixed fire-fighting systems are installed in specific areas of the ship, such as the engine room, cargo hold, and galley, to extinguish fires quickly and effectively.
Carbon Dioxide Systems: Carbon dioxide (CO2) systems are commonly used in engine rooms and cargo holds. These systems work by injecting CO2 into the protected space, displacing oxygen and extinguishing the fire. The Maritime Safety Code (FSS) specifies the required CO2 dosage based on the size of the protected space, the placement of the CO2 cylinders, and safe and effective discharge control.
Foam Systems: Foam fire-fighting systems are particularly effective on flammable liquid fires. They form a foam layer that suppresses the flames and prevents re-ignition. These systems are typically used in engine rooms and areas where fuel is stored or handled. The Maritime Safety and Security Code (FSS) specifies the permitted foaming agent types, required concentrations, and application rates.
Water Mist Systems: These systems use a fine water mist to control, extinguish, and suppress fires. Water mist systems are effective at extinguishing many types of fires, including electrical fires. The Fire Safety Standard (FSS) specifies the design and performance standards for these systems, ensuring they can quickly cool and suppress fires and minimize water damage.
Installation and Maintenance: Fixed fire-extinguishing systems must be installed according to strict standards to ensure their effectiveness. Regular maintenance, including system inspections, cylinder pressure testing, and discharge testing, is essential to keep the systems in working order.
3. Fire Detection and Alarm Systems
Early fire detection is crucial to minimizing losses and ensuring personal safety. The Maritime Safety Code (FSS) requires the installation of automatic fire detection and alarm systems in accommodation spaces, service spaces, and control stations.
Detector Types: Fire detection systems typically include smoke detectors, heat detectors, and flame detectors. Each type is designed for different fire environments and hazard sources. Smoke detectors are used in areas where early detection of active fires is crucial, while heat detectors are used in areas with rapidly rising temperatures.
System Configuration: The detection system must be configured to detect any fire and immediately activate the alarm quickly. This includes dividing the ship into fire detection zones that conform to fire boundaries and ensuring that the alarm provides clear information about the fire’s location.
Alarm and Notification: The fire alarm system must simultaneously alert crew and passengers. The alarm must be both audible and visual, ensuring it can be heard in all areas, including noisy environments. Integration with the ship’s public address and general alarm systems is crucial for effective emergency communications.
Maintenance and Testing: Regular testing and maintenance are required to ensure the reliability of the fire detection system. This includes regular inspections of detectors, alarms, control panels, and system wiring.
4. Smoke Control and Ventilation Systems
Proper ventilation and smoke control are essential to maintaining visibility and fresh air during a fire. The Maritime Safety Code (FSS) requires the installation of smoke extraction systems and fire dampers to control the spread of smoke and maintain safe evacuation routes.
Smoke Extraction Systems: These systems are designed to remove smoke from corridors, stairways, and other escape routes, improving visibility and reducing the risk of inhalation. The FSS specifies the capacity and arrangement of smoke exhaust fans and ducting.
Fire Dampers: Fire dampers are installed in ventilation ducts to prevent the spread of fire and smoke between compartments. These systems are designed to automatically close upon detecting smoke or heat. This code describes the construction, installation, and maintenance standards for fire dampers.
Pressure Systems: In certain areas, such as stairwells and escape routes, pressure systems can prevent the ingress of smoke. These systems create a pressurization in the protected area, preventing smoke from entering.
Maintenance and Testing: Regular testing and maintenance of smoke control and ventilation systems is essential. This includes checking the operation of exhaust fans, fire doors, and pressure systems to ensure they function properly in an emergency.
5. Means of Escape
Ensuring that all personnel can safely evacuate the ship in the event of a fire is a fundamental aspect of the Maritime Safety Code. The Code specifies the number, type, and location of escape routes and emergency exits, as well as the installation of emergency lighting and signage.
Escape Routes: The Maritime Safety Code requires a sufficient number of escape routes throughout the ship to ensure that all areas have escape routes. Primary and secondary escape routes must be clearly visible and unobstructed.
Emergency Exits: Emergency exits must be strategically located and easily accessible. Emergency exits must be clearly marked with light signals and equipped with emergency lighting to ensure visibility during power outages.
Emergency Lighting: Emergency lighting is essential to illuminate escape routes and exits. The Maritime Safety Code specifies the duration, intensity, and placement of emergency lighting systems.
Evacuation Plan: Detailed evacuation plans and procedures must be posted in easily accessible locations throughout the vessel. Crew members must be trained in these procedures and participate in emergency response.
6. Firefighter Equipment
The Maritime Safety Code (FSS) requires ships to carry a certain amount of firefighter equipment, including protective clothing, breathing apparatus, and other firefighting equipment. This equipment enables crew members to extinguish fires and conduct rescue operations safely.
