  1. FIRE FIGHTING

  2. FIRE TRIANGLE • FUEL • HEAT • OXYGEN

  3. EXTINGUISHING METHODS • STARVING it of fuel • SMOTHERING it – to cut off the supply of oxygen • COOLING it – to remove the heat • INHIBITING the chemical chain reaction.

  4. CLASS A FIRES • Common solid fuels • Extinguished by cooling

  5. CLASS B FIRES • Involve flammable and combustible liquids • Extinguished by smothering or inhibiting the reaction

  6. CLASS C FIRES • Involve flammable gases. • Extinguished by starving of fuel

  7. CLASS D FIRES • Involve combustible metals. • Extinguished by special smothering methods

  8. ELECTRICAL FIRES • Not an official class • Not a fuel • Extinguished by smothering or inhibiting reaction • Medium need to be non conducting. • Extinguishers have (E)

  9. CLASS F FIRES • Involve combustible fats and oils • Often in deep fryers • Special smothering or chemical methods

  10. WATER

  11. FOAM

  12. DRY POWDER

  13. CO2

  14. VAPORISONG LIQUID

  15. WET CHEMICAL

  16. FIRE BLANKETS

  17. RESPONSE PRECEDURES • REMOVE PEOPLE from immediate danger. • ALERT nearby staff and members of the public. • CONFINE FIRE and SMOKE close windows and doors (if safe to do so). • EXTINGUISH or control fire (if safe to do so).

  18. CONSIDERATIONS • What sort of fire is this? • Do I have the training and equipment to safely handle it? • What sort of hazards are involved? • What precautions do I need to take? • Is it worth the risks involved to fight the fire?

  19. HOW TO EXTINGUISH • P ull out the safety pin, test the extinguisher • A im at the base of the fire. • S queeze the operating handle. • S weep the stream of firefighting agent back and forth across the base of the fire

  20. REMEMBER SAFETY FIRST
