14. 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
Don’t 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
Don’t 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
