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 significant threat to property and human life
Fire fighting systems are designed to detect, control, and extinguish fires

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
Heat detectors: activate alarms when a predetermined temperature threshold is exceeded
Flame detectors: use sensors to detect the presence of flames
Fire alarm control panels: receive signals from detectors, activate audible and visual alarms, and alert occupants to evacuate

Fire Suppression Systems

Designed to extinguish or control fires
Sprinkler Systems: Network of pipes with sprinkler heads strategically placed throughout the building. 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 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 (water, dry chemical, CO2, and foam)
Each type 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 (corridors, stairwells, exits)
Ensure visibility in low-light conditions or during power outages

Fire Alarm System

Serves as the central control unit for fire detection and alarm components
Receives signals from detectors and activates audible and visual alarms to alert occupants and emergency responders to the presence of a fire
Notifies building management or a central monitoring station about the fire event

Fire Doors and Fire-rated Partitions

Designed to prevent the spread of fire and smoke
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
Include evacuation route signs, fire assembly point signs, and fire extinguisher location signs
Clear instructions and signage facilitate safe and orderly evacuation procedures

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
Allow firefighters to access water quickly and efficiently to combat fires

Types of Fire Protection Systems

Active systems: designed to put out fires
Passive systems: designed to prevent fires from starting

Active Fire Protection

Sprinkler systems: release water onto the fire
Fire alarms: alert people to the presence of fire
Fire extinguishers: portable devices used to quickly suppress small fires

Passive Fire Protection

Door closures: automatically close when smoke or gases are detected
Automatic shut-off valves on gas lines
Smoke curtains: prevent smoke from entering areas
Emergency lighting: provides light even when power is out

Example of Passive Fire Protection

Fire-rated glazing materials in educational and healthcare structures
Fire retardants for curtains, draperies, carpeting, furniture, and fixtures

Types of Fire Fighting Systems: Material

Wet Pipe Sprinkler Systems
Dry Pipe Sprinkler Systems
Deluge Sprinkler Systems
Carbon Dioxide Systems

Operation of Fire Fighting Systems

Detection
Alarm and Notification
Fire Suppression
Monitoring and Control

Importance of Fire Fighting Systems

Life safety
Property protection
