Study Notes
Brief History of Bureau of Fire Protection (BFP)
- 1900: First fire department established in Manila
- 1940: Fire departments established in neighboring cities and towns
- 1975: Integration of local fire departments in the city
- 1977: First fire code in the Philippines enacted
- 1990: Republic Act No. 6975 established a separate Bureau of Fire Protection
- 2008: Republic Act No. 9514 revised fire code of the Philippines enacted
What is Fire?
- Fire is a rapid, self-sustaining oxidation process of combustible materials
- Accompanied by the evolution of heat and light of varying intensity
- Fire spreads quickly, becoming life-threatening in 2 minutes and engulfing in flames in 5 minutes
- Fire produces deadly smoke and toxic gases, making it difficult to breathe and causing disorientation
Elements of Fire
- Oxygen: at least 16% required, but normal is 21%
- Heat: enough to make the fuel ignite and burn
- Fuel: something that burns, such as paper, plastic, cloth, wood, or flammable liquids like alcohol
Tetrahedron of Fire
- Oxygen sources: some fuel materials contain oxygen to support burning
- Heat sources: open flames, sun, hot surfaces, sparks, arcs, friction, chemical action, electrical energy, and compression of gases
- Fuel: solid, liquid, or gas
Stages of Fire
- Ignition/incipient stage: fire is small, hard to detect, and confined to the fuel that ignited
- Growth stage: temperature and smoke increase, oxygen level decreases, and fuel is dried out
- Flashover stage: huge smoke is present, and fire is spreading to other furniture
- Fully developed stage: all materials are burning, and maximum heat is released
- Decay stage: intensity of fire is decreasing due to lack of fuel
How Fire Spreads
- Direct heat transfer (conduction)
- Convection: transfer of heat through the movement of heated fluids
- Radiation: transfer of heat through electromagnetic waves
Classes of Fire
- Class A: ordinary combustible materials (wood, cloth, paper, plastic, etc.)
- Class B: flammable or combustible liquids (gasoline, alcohol, paint, hairspray, etc.)
- Class C: energized electrical equipment (electric fan, microwave, TV, stove, etc.)
- Class D: combustible metals (magnesium, titanium, sodium, potassium, etc.)
- Class K: cooking media
How to Put Out a Fire
- Cooling: reducing temperature
- Smothering: excluding oxygen
- Fuel removal: removing the fuel source
- Inhibition: breaking the chemical reaction
- Reduction of heat: using something that absorbs heat, such as water or foam
- Exclusion of oxygen: closing the door, diluting oxygen, or blanketing with a wet blanket or foam
- Removal of fuel: turning off fuel supply or moving combustible materials
- Inhibition of chain reaction: breaking the chain reaction
Fire Extinguisher Use
- P: Pull the pin
- A: Aim at the base of the fire
