- Semester: First Semester 2024/2025
Topic 7: Fire Fighting System
- Fire is a destructive force causing property damage and endangering lives.
- A fire fighting system detects, controls, and extinguishes fires swiftly and efficiently, preventing losses, safeguarding lives, and preserving 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 presence in a building.
- Components typically include smoke detectors, heat detectors, flame detectors, and fire alarm control panels.
- Smoke detectors: Use optical or ionization sensors to detect smoke, triggering an alarm.
- Heat detectors: Activate alarms when a predetermined temperature threshold is exceeded.
- Flame detectors: Employ sensors to detect flames and activate alarms.
- Fire alarm control panels: Receive signals from detectors, activating audible and visual alarms to alert occupants for evacuation.
Fire Suppression Systems
- Designed to extinguish or control fires once detected.
- Sprinkler systems: Consist of a network of pipes with sprinkler heads strategically positioned throughout the building. When heat from a fire activates a sprinkler head, it releases water to suppress the fire.
- Gaseous suppression systems: Use inert gases or chemical agents to extinguish fires by displacing oxygen or inhibiting chemical reactions sustaining combustion.
- Foam systems: Combine foam concentrate with water to create a foam blanket that smothers flammable liquid fires, suppressing 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 fire types.
Emergency Lighting and Exit Signs
- Essential for guiding occupants to safety during a fire emergency.
- Provide illumination along escape routes, such as corridors, stairwells, and exits, ensuring visibility 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, alerting 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 and equipped with self-closing mechanisms to seal off compartments and contain fires.
Fire Safety Signage and Instructions
- Vital information for occupants during a fire emergency.
- Includes evacuation route signs, fire assembly point signs, fire extinguisher locations, clear instructions, and signage facilitating safe and orderly evacuation procedures.
Fire Hose Reels and Standpipes and Fire Pump
- Provide a ready source of water for firefighting.
- Typically installed in strategic locations, allowing firefighters to quickly and efficiently access water to combat fires.
Types of Fire Fighting Systems
- Active systems designed to put out fires.
- Passive systems designed to prevent fires from starting.
- Examples include Sprinkler Systems, Dry Pipe Sprinkler Systems, Deluge Sprinkler Systems, and Carbon Dioxide Systems (active).
- Fire-rated glazing materials and fire retardants (passive).
Operation of Fire Fighting Systems
- System aims to automatically respond to fire events.
- Typically involves detection, alarm and notification, fire suppression, and monitoring and control steps.
Importance of Fire Fighting Systems
- Life safety: Protect human lives by detecting fires early, allowing for rapid evacuation and response.
- Property protection: Minimize damage to property by controlling or extinguishing fires before growth.
- Compliance with regulations: Meets building and fire safety regulations for commercial, industrial, and residential buildings.
- Minimizing business disruption: Avoid prolonged closures, maintain operations, and reduce downtime.
- Insurance benefits: Some insurance providers offer reduced premiums to buildings equipped with modern fire fighting systems.
