Fire Extinguisher Safety

There is always the possibility of a fire happening on campus, fire extinguishers can help minimize property damage and save lives if used properly. Stationed throughout campus, portable fire extinguishers are to be used on small or the beginning stages of a fire, not on a large-scale fire. Always call 911 and activate the fire alarm by pulling a fire pull station near an exit in the event of any size fire prior to using a fire extinguisher. 

Fire Extinguisher TrainingYou may attempt to extinguish the fire with a fire extinguisher if ALL of the following are present:

  • You have been trained in the use of fire extinguishers
  • The fire alarm has been activated and the building is evacuating 
  • The fire is small (waste basket size) and contained
  • You have the correct type of extinguisher
  • Your exit is clear, and you can fight the fire with your back to the door/ exit

Type of Fire Extinguishers 

  • Class A: For solids that do not include metal; examples are wood, paper, plastic and cloth 
    • Water or Air Pressurized Water can fight Class A fires only
  • Class B: For Flammable Liquids; examples are grease, gas, oil and acetone
    • Carbon Dioxide (CO2) can fight Class B and C fires 
    • If handheld Class B unit:
      • This method displaces the oxygen to stop fire. So do not use in an enclosed space, and have proper ventilation. 
      • Caution should be taken of the nozzle, which can get very cold and possibly cause frostbite.
  • Class C: For Electrical Fires; examples are energized equipment
  • Class D: For Combustible Metal; examples are potassium, sodium, aluminum, magnesium
  • Class K: Kitchen Fires; for vegetable oil or fats
  • Note: If you do not know what is burning in the fire, let the fire department handle the situation

Harper College uses an ABC combination fire extinguisher, which can be used on solids, flammable liquids or electrical fires, just not metal fires.
