🔥 Fire Fighting System – Main Components & Functions

A fire-fighting system is designed to detect, control, suppress, and help contain fires while protecting people, property, and critical equipment.

🔹 1. Water Tank
Stores the required firefighting water and provides a reliable water source.

🔹 2. Jockey Pump
Maintains system pressure and compensates for small pressure losses without starting the main fire pump.

🔹 3. Fire Pump
Delivers the required water flow and pressure to the firefighting network during a fire emergency.

🔹 4. Fire Pump Control Panel
Controls pump operation and provides status indication, alarms, and monitoring.

🔹 5. Fire Fighting Riser
Main vertical pipe that distributes water to sprinklers, hose reels, and hydrant systems.

🔹 6. Sprinkler System
Automatically releases water when the sprinkler operates due to sufficient heat, helping control fire at an early stage.

🔹 7. Hose Reel Cabinet
Provides a readily available hose for initial firefighting by trained/authorized personnel.

🔹 8. Fire Extinguisher
Provides portable first-response fire protection; the extinguisher type must match the applicable fire class.

🔹 9. Alarm & Detection System
Detects fire conditions and gives audible/visual warnings so occupants can respond quickly.

📌 Key Sequence:
Fire Detection → Alarm → Pump Start → Water Distribution → Sprinkler/Hose/Hydrant Operation → Fire Suppression

⚠️ Actual system design, equipment selection, water storage, pump capacity, and installation should comply with the applicable local fire code, authority requirements, and project standards.

🔥 WHY DOES LEL MATTER ONBOARD?

LEL = Lower Explosive Limit

LEL tells us how close a flammable gas or v***r concentration is to its lower flammable limit.

🟢 WHAT IS THE SAFEST LEL READING?

0% LEL is the safest and ideal detector reading.

It means the gas detector is not detecting flammable gas above its detection threshold.

However:

⚠️ 0% LEL does NOT mean absolutely zero gas is present.

Every gas detector has a detection limit and measurement uncertainty.

🔥 WHY DOES LEL MATTER?

As the LEL reading increases, it indicates that more flammable gas is being detected in the atmosphere.

The objective is to detect the gas early and prevent the atmosphere from reaching a flammable concentration.

⚓ WHERE IS LEL IMPORTANT?

LEL monitoring is especially important during:

• Enclosed-space entry
• Tank cleaning and gas freeing
• Hot work
• Cargo operations
• Bunkering
• Fuel-system maintenance
• Work in areas where flammable v***rs may accumulate

🚨 IMPORTANT!

0% LEL alone does NOT mean the atmosphere is safe.

Before entering or starting work, also verify:

✅ Oxygen concentration
✅ Toxic gases such as H₂S and CO, where applicable
✅ Ventilation
✅ Isolation and line blanking
✅ Permit-to-work requirements
✅ Vessel SMS procedures
✅ Applicable regulations

🧠 REMEMBER

0% LEL = safest and ideal detector reading.

But:

0% LEL ≠ automatically safe atmosphere.

Test. Verify. Control.

⚓ Detect Early. Prevent Accidents.

🔥 HOW DOES A FIRE GET EXTINGUISHED?

To understand how we put out fire, first understand what keeps it burning: heat, fuel, oxygen, and a chemical chain reaction. Together, these make up the fire tetrahedron.

Fire extinguishment works by removing or interrupting one of these elements:

💧 Cooling — removes heat.
🫧 Smothering — limits the fire’s access to oxygen.
⛽ Starvation — removes or shuts off the fuel.
🧯 Chain reaction interruption — interferes with the chemical reaction that sustains combustion.

Fire-Fighting Equipment on Board - Basic Things To Know ✅⚓️

Fire-fighting equipment is essential for preventing, controlling, and responding quickly to fires at sea.

1. Portable Fire Extinguishers – Used for initial fire attack. The correct type must be selected according to the class of fire.
2. Fire Hose, Hydrant & Nozzle – Provides a continuous supply of water for fighting larger fires. Crew should know how to connect, deploy, and operate them.
3. Firefighter’s Protective Outfit – Includes protective clothing, helmet, gloves, boots, and other equipment to protect personnel from heat, smoke, and injury.
4. SCBA – Supplies breathable air and allows trained personnel to enter smoke-filled or oxygen-deficient areas.
5. Fire Blanket – Used mainly to smother small fires, such as cooking or burning clothing.
6. Fire Detection & Alarm System – Detects fire early and alerts the crew so that emergency procedures can begin immediately.

Key point: Effective fire response depends not only on having the equipment available, but also on proper training, regular drills, correct operation, and immediate action.

🔥 How Fire Alarm System Works?

A Fire Alarm System continuously monitors the building for smoke, heat, or other fire conditions and sends an alarm signal to warn occupants and initiate connected safety actions.

1️⃣ Smoke / Heat Detector — Detects

🔥 Smoke Detector: Detects smoke particles.

🌡️ Heat Detector: Detects a preset temperature or rapid temperature rise.

Function: Senses a possible fire condition and sends a signal to the fire alarm panel.

2️⃣ FACP — Receives the Signal

FACP = Fire Alarm Control Panel

Receives signals from detectors and manual call points.

Monitors system status, faults, and alarm conditions.

In an addressable system, it can identify the individual device/location.

3️⃣ FACP — Processes & Decides

Checks the incoming alarm signal.

Identifies the zone/device involved.

Activates the programmed alarm sequence.

4️⃣ Notification & Interface — Takes Action

🔊 Ho**er/Sounder: Produces an audible alarm.
🚨 Strobe: Provides visual warning, especially useful in noisy areas.
🖥️ BMS Interface: Sends fire/alarm status to the Building Management System when integrated.
📞 Dialer/Communicator: Can transmit alarm information to a designated monitoring/response system.

5️⃣ Addressable vs Conventional Loop

📍 Addressable: Each compatible device has a unique address, allowing more precise identification.
📍 Conventional: Devices are grouped into zones, so the panel generally identifies the affected zone, not an individual detector.

🔧 Main Types

Addressable: Smart, individual device identification, more detailed monitoring.

Conventional: Zone-based system, generally simpler and economical.

Wireless: Uses wireless communication between compatible devices and the control system; useful where wiring is difficult.

⚡ Power Supply

24V DC nominal system supply is common, with a standby battery to maintain operation during mains failure. Actual voltage, battery capacity, and required standby duration must follow the applicable fire-code/system design.

🔄 Simple Working Flow

Smoke/Heat → Detector → FACP → Alarm Processing → Ho**er + Strobe → BMS/Dialer

🔥 Early detection + fast notification = faster emergency response.
