  1. MODUL 1 FIRE EXTINGUISHERS

  2. HOW DOES A FIRE WORK? • Three components • Need all three components to start a fire • Fire extinguishers remove one or more of the components

  3. FIRE CLASSIFICATIONS • Class A - ordinary combustibles • Class B - flammable liquids / oil, gas, grease • Class C - electrical fires e.g Electrical, energized, electrical equipment • Class D - metals fires / Combustible metals

  4. FIRE EXTINGUISHER TYPES • Extinguishing agent eliminates one of the vital elements of the fire • Many types of extinguishers available • Know location of extinguishers

  5. DIFFERENT KINDS OF EXTINGUISHERS • The 4 most common fire extinguishers: • All Purpose Water • Carbon Dioxide • Multi-Purpose Dry Chemical • Dry Powder • Each kind of extinguisher has a specific use

  6. ALL PURPOSE WATER • Use on CLASS A fires • Pressurized water • Pressure gauge present

  7. CARBON DIOXIDE • Use on CLASS B and CLASS C fires • Hard, plastic nozzle • No pressure gauge

  8. MULTI-PURPOSE DRY CHEMICAL • Use on CLASS A, CLASS B, and CLASS C fires • Fine powder under pressure • Pressure gauge present

  9. APPROPRIATE USE OF EXTINGUISHERS • Alarm has been sounded • Building has been evacuated • Fire is small and confined

  10. APPROPRIATE USE OF EXTINGUISHERS • You can fight the fire with your back toward an escape route • The extinguisher matches the fire type • The extinguisher works effectively

  11. APPROPRIATE USE OF EXTINGUISHERS • You are properly trained in the use of the extinguisher • You are confident you can put the fire out • Remember to keep an exit to your back • Only fight a fire in the incipient stage

  12. INAPPROPRIATE USE OF EXTINGUISHERS • The fire is large and has grown beyond its original confined space • Your escape path is threatened • You are not sure if you have the correct type of fire extinguisher • Don’t have the proper extinguisher or equipment • Fire has spread beyond its point of origin • Your instincts tell you GET OUT

  13. PERSONAL HAZARDS • Smoke and noxious fumes • Smoke and fumes cause unconsciousness • Death may result

  14. PASS METHOD OF FIGHTING FIRES Hold the extinguisher upright • Pull the pin • Aim at the base of the fire • Squeeze the handle • Sweep the base of the fire Do not aim high at the flames

  15. P.A.S.S. METHOD PULL THE PIN This will allow you to squeeze the handle in order to discharge the extinguisher

  16. P.A.S.S. METHOD AIM AT THE BASE OF THE FIRE Aiming at the middle will do no good. The agent will pass through the flames.

  17. P.A.S.S. METHOD SQUEEZE THE HANDLE This will release the pressurized extinguishing agent

  18. P.A.S.S. METHOD SWEEP SIDE TO SIDE Cover the entire area that is on fire. Continue until fire is extinguished. Keep an eye on the area for re-lighting.

  19. PREVENTION METHODS • Keep work areas clean and clutter-free • Know how to handle and store chemicals • Know what you are expected to do in an emergency

  20. PREVENTION METHODS • Know about the chemicals you work with • Become familiar with emergency action plan for fires

  21. IN THE EVENT OF FIRE • Pull nearest alarm station • Immediately exit the building If you hear an alarm DO NOT assume it is a drill, your life may depend on it!

  22. EMERGENCY PROCEDURES Building Evacuation • Proceed to nearest exit in an orderly fashion • Assemble at least 100 feet from building • Provide emergency crews with information about people still in the building • Provide information to emergency crews about the reason for evacuation • Neverre-enter a building until instructed to by the police department, fire department, or EHS staff.
