Course Information
- Course Title: Electrical and Mechanical Systems
- Course Code: AE 475
- Instructor: Dr. Muna M. Alibrahim
- Institution: Yarmouk University
- Semester: First Semester 2024/2025
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.
