3
Types of Fires and Fire Extinguishers
  • Type A - Burning wood, paper, or textile material
  • Type B - Flammable liquids
  • Type C - Electrical
  • Type D - Combustible metals
  • ABC Extinguisher
  • Know how to use it

Elements of Combustion
  • Combustion - The continuous, self-sustaining
    process in which fuel and oxygen molecules
    combine to yield heat, gas, smoke, and flame.
  • Pyrolysis - chemical decomposition of matter
    through the action of heat
  • Ignition temperature or kindling point - minimum
    temperature for fuel to be reached before it
    reacts with oxygen and begins to burn

15
Elements of Combustion
  • Four elements or conditions needed for
    combustion
  • fuel
  • heat
  • oxygen
  • chemical reaction

16
Leading causes of residential fire deaths
  • Cigarette ignition
  • Heating
  • Incendiary/suspicious
  • Children playing
  • Cooking
  • Electrical
  • All other causes

17
Fire prevention in the home (1)
  • Have rules regarding smoking
  • Dont overload electrical circuits
  • Make sure cords and wires are in good condition
  • If you use wood stoves or fireplaces, make sure
    they are properly installed and maintained
  • Rules for electric and kerosene heaters

18
Fire prevention in the home (2)
  • Keep smoking materials, including matches and
    lighters out of the reach of children
  • Keep combustible materials away from kitchen
    stove and oven
  • Turn pot and pan handles inward
  • Dont accumulate combustible materials
  • Be aware of spontaneous combustion and its causes

19
Project EDITH (Exit Drills in the Home)
  • Smoke detectors
  • Floor plans and escape routes
  • Alert others
  • Stay low
  • Check doors
  • Keep smoke out if possible
  • Have prearranged meeting place
  • Once out, stay out
  • Notify fire department

20
RCA - Rescue, Confine, Alarm
  • Used in larger buildings - hospitals, office
    buildings, universities
  • Rescue - warn or rescue those in immediate smoke
    or fire danger
  • Confine - close doors to prevent the spread of
    fire or smoke
  • Alarm - operate nearest fire alarm or call fire
    department

21
Fire detection devices
  • Heat detectors - not for use in residences
  • Photoelectric smoke detector
  • Ionization chamber smoke detector
  • Smoke detectors should be
  • on each floor level
  • away from vents
  • maintained properly
  • preferably near sleeping areas

22
Using a fire extinguisher
  • Time is important - use a fire extinguisher only
    in the first few minutes of a fire.
  • Break seal, pull pin and test
  • Aim low and about 6 to 10 feet away
  • Aim extinguisher at base of the flame
  • Use sweeping motion
