L6-Life Safety and Systems in Buildings (Part 1) Flashcards
Through the enactment of the RA 6975, also known as the ___________________, the Fire Service was separated from the PC-INP as a separate and distinct agency as __________________ on August 2, 1991.
-DILG Act of 1990
-Bureau of Fire Protection
It is mandated to prevent and suppress
destructive fires, conduct investigation,
provide emergency medical and rescue
services and enforce the Republic Act 9514
Bureau of Fire Protection
What is R.A. 9514?
Fire Code of the Philippines of 2008
What are the Implementing Rules and Regulations in the Revised Fire Code of the Philippines?
-Fire Safety Inspections
-Fire Safety Seminar
-Fire Drills
-Fire Brigade for establishments
employing at least 50 persons
____% of all structure fires occurred in residential properties.
76
____% of structural fire deaths occurred in residential properties
97
People feel the safest in their homes, however residential properties are where most fires and fire deaths occur. (TRUE OR FALSE)
TRUE
What are the top fire causes?
– Cooking (49%)
– Open Flame (10%)
– Heating (9%)
– Incendiary/Arson (8%)
– Smoking (4%)
It is the active principle of burning, characterized by the heat and light of combustion (RA 9514)
Fire
It is a rapid oxidation process accompanied with the evolution of light and heat of varying intensities.
Fire
What is in the tetrahedron of fire?
Heat, Fuel, Oxygen (oxidizing agent)
-all necessary to produce a fire
What are the stages of Fire?
-Ignition Stage
-Growth Stage
-Flash Over
-Fully Developed
-Decay
In this stage, there is plenty of oxygen, little heat and
smoke
Ignition Stage
In this stage, the oxygen level decreased and the fuel is already dried out. This can be continuous if there is enough fuel
and oxygen.
Growth Stage
In this stage, there is a presence of huge smoke which indicates
the rapid change of situation. This is where the Gasses are generated by heat.
Flash Over
In this stage, All combustibles materials present are continuously burning. While unburned gasses begin flowing to adjacent spaces and ignite once it enters a space where air more abundant.
Fully Developed
In this stage, intensity of fire decreasing due to lack of available fuel.
Decay
In this stage, Temperature and smoke level increases. Hot gasses rise to the ceiling and spreads outward the walls.
Growth stage
It is the Transition between growth and fully developed stage. In addition, there is an increasing level of smoke with decreased visibility.
Flash Over
In this stage, maximum amount of heat is released and the volume of fire is dependent of the number and size of ventilation openings.
Fully Developed
What are the Methods of Heat Transfer?
-By Radiation
-By Convection
-By Conduction
-By Direct Contact
It is the transmission of heat energy through electromagnetic wave.
Radiation
It is the transfer of heat energy by the movement of heated
fluids.
Convection
It is the transmission of heat from one body to another. It is the transfer of heat from one molecule to another molecule
Conduction
What is in the Fire Extinguishment Theory?
-Cooling-temperature reduction
-Smothering-oxygen dilution
-Fuel Removal
-Inhibition-breaking the chemical reaction
- Use something that absorb heat
- Use water being the best cooling agent
- Use foam which contains 94% water
Reduction of Heat
- Secure the door at close position
- Displacement or diluting oxygen by means
of CO2 - Blanketing- using wet blanket as foam
Exclusion of Oxygen
- Shut Off Fuel Supply
- Relocate flammable/ combustible materials
Removal of Fuel
- Break the Combustion Chain
Inhibition of Chain Reaction
A fire is classified according to the _______ it consumes.
fuel
Fires caused by ordinary combustibles or fibrous material, such as wood, paper, cloth, rubber and some plastics are classified as _______
Class A
Fires caused by flammable or combustible liquids such as gasoline, kerosene, paint, paint thinners and propane are classified as _______
Class B
Fires caused by energized electrical equipment, such as appliances, switches, panel boxes and power tools are classified as _______
Class C
Certain combustible metals, such as magnesium, titanium, potassium and sodium. They may react violently with water or other chemicals, and must be handled with care. Fire involved with these materials is classified as ________
Class D
Fires involving combustible cooking fluids such as oils and fats are classified as ________
Class K
