Physical Science P1

• Combustion or burning of substance combined chemically with oxygen from the air, giving off light and heat.

  Fire
• This is needed to sustain a combustion.

  Oxygen
• There must be _ or combustible material.

  fuel
• Stages of Fire (Indians Go Full Derivation)

  Ignition Stage, Growth, Fully Developed, Decay or Burnout
• Sufficient heat is needed to raise the material to its ignition temperature
• Stage of fire: Fuel and oxygen are exposed to heat.

  Ignition Stage
• Stage of fire: Heat is transferred igniting more materials.

  Growth
• Stage of Fire: Fire spreads, temperature reached its peak.

  Fully Developed
• Stage of fire: Fire consumes all available fuel, temperature decreases

  Decay or Burnout
• Class of Fire; Ordinary combustible materials: wood, paper, plastic, fire crackers.

  Class A
• Classes of Fire: Flammable liquids and chemicals such as LPG.

  Class B
• Class of Fire: Electricity

  Class C
• Class of Fire: Combustible Metal

  Class D
• Class of Fire: Commercial Cooking Oil

  Class K
• P in the acronym TPASS to operate an extinguisher stands for:

  Pull the Pin
• A in the acronym TPASS to operate an extinguisher stands for:

  Aim the nozzle at the base of fire
• The first S in the acronym TPASS to operate an extinguisher stands for:

  Squeeze the handle
• The second S in the acronym TPASS to operate an extinguisher stands for:

  Sweep the nozzle side to side
• Bureau of Fire Protection Contact Number in Cebu City

  [phone]
• One of the most significant discoveries during the ancient times

  Fire
• Types of Fire: Pyroclastic materials and lava flow

  Fire due to Natural hazards
• Type of fire caused by volcanic eruption, drought, and high temperatures.

  Fire due to natural hazards
• Type of fire caused by transportation accidents, chemical expolosion, faulty electrical connections.

  Fire due to Human-made Conditions
• Type of fire: Overheating of electrical wirings

  Fire due to human-made conditions
• Type of fire due to the negligence, irresponsible handling of fire

  Fire due to mismanagement
• Type of fire: Lighted candle left unattended

  Fire due to mismanagement
• As smoke rises, stay low on the ground, crawl on your hands and knees
• If your clothing catches fire, immediately stop, drop to the ground, and roll with your hands and face.
• When calling a fire emergency, give the following details;

  1. Location and Landmark
  2. Name
  3. Number
• Mission of BFP is 80% fire prevention, 19% fire supression and 1% EMS Rescue.
• The 3 components of chemical reaction chain is Oxygen, Fuel and Heat.
• The direct transmission of heat from one body to another.

  Conduction
• The transfer of heat energy by the movement of heated fluids (air or liquid).


  Convection
• The transmission of heat energy through electromagnetic wave.

  Radiation
• The T in the acronym TPASS stands for:

  Twist the Pin
• Methods of Extinguishing - Temperature Reduction

  Cooling
• Methods of Extinguishing - Fuel Removal

  Starving
• Methods of Extinguishing that includes blanketing and smothering

  Oxygen Dilution
• Methods of Extinguishing - makes use of foam to extinguish fire

  Inhibition of the Chain Reaction
• Triage: What does the color red signify?
