  • Fire Triangle
    • Combustion is a chemical process in which a substance reacts rapidly with oxygen giving off heat as a result
    • The original substance is called fuel
  • Elements required for fire
    • Fuel
    • Heat
    • Oxygen
  • Fuel - For a fire to start, there should be a material to burn at the first place
  • Flammable materials give off flammable vapors which, when heated, burst into flames
  • Oxygen - Air around us is approximately 21% oxygen and, since most fires only need at least 16% oxygen to burn, oxygen in our environment becomes oxidizing agent in this chemical reaction
  • Sources of Ignition
    • Lit (lighted) cigarettes, matches, and lighters
    • Open flames from lit candles, cooking stoves, camp fires
    • Hot processes and hot surfaces
    • Electrical equipments which are switched on
    • Static electricity
  • Sources of Fuel
    • Flammable Paper, saw dust, cardboard
    • Fabric, any soft furnishing
    • Plastic
  • Sources of Oxygen
    • Hydrogen peroxide
    • Fluorine, Chlorine, and other halogens
    • Nitric acid and other nitric compounds
    • Sulfuric acid
  • Fire extinguisher
    A device that discharges a jet of water, foam, gas, dust, or other materials to put off fire
  • Types of Fire Extinguisher
    • Water (APW) Fire Extinguisher
    • Carbon Dioxide Fire Extinguisher
    • Dry Chemical Fire Extinguisher
  • Fire Safety Equipment
    • Fire Hydrant
