Topic 7: Fire Fighting System

Fire is a devastating force that can cause significant damage to property and endanger lives.
Fire fighting systems are designed to detect, control, and extinguish fires swiftly and efficiently. This also prevents losses from fires, protects lives, and preserves property.

Main Components of a Fire Fighting System

Fire detection systems (smoke detectors, heat detectors)
Fire suppression systems (sprinklers, gaseous suppression systems)
Fire extinguishers
Emergency lighting and exit signs
Fire alarm systems
Fire doors and fire-rated partitions
Fire safety signage
Fire hose reels and standpipes and fire pump

Fire Detection Systems

Designed to identify fire or smoke.
Include smoke detectors, heat detectors, flame detectors, and fire alarm control panels.
Smoke detectors: Use optical or ionization sensors to detect smoke particles, triggering an alarm when smoke is detected.
Heat detectors: Activate alarms when a predetermined temperature threshold is exceeded, indicating the presence of fire.
Flame detectors: Use sensors to detect the presence of flames and activate alarms accordingly.
Fire alarm control panels: Receive signals from detectors and activate audible and visual alarms to alert occupants to evacuate.

Fire Suppression Systems

Designed to extinguish or control fires once detected.
Sprinkler Systems: Network of pipes with strategically placed sprinkler heads. When heat from a fire activates a sprinkler head, water is released to suppress the fire.
Gaseous Suppression Systems: Use inert gases or chemical agents to extinguish fires by displacing oxygen or inhibiting chemical reactions that sustain combustion.
Foam Systems: Combine foam concentrate with water to create a foam blanket that suppresses flammable liquid fires by smothering the flames and cooling the fuel surface.

Fire Extinguishers

Portable devices used to extinguish small fires or control fires in their early stages.
Available in various types, including water, dry chemical, CO2, and foam extinguishers, each suitable for different types of fires.

Emergency Lighting and Exit Signs

Essential for guiding occupants to safety during a fire emergency.
Provide illumination along escape routes.
Ensure visibility even in low-light conditions or power outages.

Fire Alarm System

Serves as the central control unit for fire detection and alarm components of the fire fighting system.
Receives signals from detectors and activates audible and visual alarms to alert occupants and emergency responders to the presence of a fire.

Fire Doors and Fire-Rated Partitions

Designed to prevent the spread of fire and smoke within a building.
Constructed of fire-resistant materials equipped with self-closing mechanisms to seal off compartments and contain fires.

Fire Safety Signage and Instructions

Provide vital information to occupants during a fire emergency.
Clear instructions and signage help facilitate safe and orderly evacuation procedures.
Examples include evacuation route signs, fire assembly point signs, and fire extinguisher location signs.

Fire Hose Reels and Standpipes and Fire Pump

Provide a ready source of water for firefighting purposes.
Typically installed in strategic locations throughout the building, allowing firefighters to access water quickly and efficiently to combat fires.

Types of Fire Protection Systems

Active systems: Designed to put out fires (e.g., sprinklers, fire alarms, fire extinguishers).
Passive systems: Designed to prevent fires from starting (e.g., fire-rated glazing materials, fire retardants, door closures).

Types of Fire Fighting Systems: Material

Wet pipe sprinkler systems: Water filled at all times, activates when fire detected.
Dry pipe sprinkler systems: Filled with pressurized air or nitrogen, water releases when fire detected.
Deluge sprinkler systems: Simultaneously activates all sprinkler heads when fire detected.
Carbon dioxide systems: Floods with carbon dioxide gas; suffocating fire by displacing oxygen; for unoccupied areas only.

Operation of Fire Fighting Systems

System automatically responds to fire events.
The operation typically involves the following steps: detection, alarm & notification, fire suppression, monitoring & control.

Importance of Fire Fighting Systems

Life safety: Protect human life by detecting and responding to fires.
Property protection: Minimize damage to property by controlling or extinguishing fires.
Compliance with regulations: Mandate installation of fire-fighting systems.
Minimize business disruption: Avoid prolonged closures.
Insurance benefits: Reduced premiums for buildings equipped with modern fire-fighting systems.
