Study Notes
Objectives of Fire Protection Program
- The objective of fire protection in a building is to maintain life safety.
- Protection of property is paramount.
- Minimize business interruption is an important focus.
Key Elements of Fire Protection
- Early Detection & Alarm System is necessary for timely response.
- Means of Egress are vital for safe evacuation.
- Compartmentation prevents fire spread within a building.
- Smoke Control is essential for reducing smoke hazards.
- Fire Suppression System is used to extinguish flames.
- Emergency Power ensures continued operation of vital systems.
Fire Hazards Triangle
- Smoke, heat, and time are the key elements of fire.
Detection & Alarm System
- Detectors are the signal initiators for fire detection and alarm systems.
- Heat detectors are cost-effective but require time to detect fire.
- Smoke detectors are effective in detecting smoldering fires.
- Ionization detectors are sensitive but prone to false alarms.
- Flame detectors are suited for fires without preceding smoke.
- Water flow detectors are used in conjunction with sprinkler systems.
- Manual pull stations manually activate the alarm system.
- Alarms are used to alert occupants to evacuate.
- Fire alarm triggers fire suppression systems and other functions.
- Alarm indicators use signals like sirens, bells, or flashing lights.
- Annunciation indicates the exact location of the alarm source.
- Electric Supervision alerts when the power supply is interrupted.
- Emergency Power ensures the alarm system operates during power outages.
Exits: Means of Egress
- Elevators have smoke shafts that carry smoke upwards.
- Elevator codes require automatic systems to ensure elevator return to a safe floor in emergencies.
- Exit signs provide clear guidance for safe evacuation routes.
Compartmentation
- Compartmentation divides a building into separate enclosures.
- Fire barriers are used to confine fire, heat, smoke, and toxic gases to the area of origin.
- Areas of refuge provide safe spaces for occupants until rescue arrives.
Smoke Control
- Smoke accounts for more than 80% of fire-related casualties.
- Smoke control methods aim to reduce smoke hazards.
- Smoke management passively manages smoke using barriers and vents.
- Smoke control systems use fans and pressure differences to control smoke movement.
Fire Suppersion
- Fire sprinkler systems are designed to suppress fire.
- Wet pipe systems rely on heat to open sprinklers.
- Dry pipe systems are filled with air and water is released upon triggering the alarm.
- Pre-action systems hold back water until an alarm is received.
- Deluge systems release water to all sprinklers simultaneously.
- Water fog systems are used for highly flammable materials.
- Liquid Foam systems smother fire and minimize water usage.
Special Fire Suppression System
- Automatic gas systems use gases to extinguish fire.
- Carbon dioxide systems are suitable for flammable vapor situations.
- Halogenated hydrocarbon systems interfere with fire chemistry.
- High-expansion foam systems use water efficiently in confined areas.
- Dry chemicals suppress fire by releasing sodium bicarbonate into the plenum chamber.
Manual Fire Fighting System
- Fire extinguishers and fire hose cabinets (FHC) are manual fire-fighting tools.
- Standpipe systems distribute water to hose stations for controlled firefighting.
- Outdoor siamese connections can supply additional water to standpipe systems.
