Fire Extinguisher
Fire extinguishers can be a valuable tool in protecting life and property if used correctly. They can completely extinguish a small fire or slow its progress until the fire department arrives.

You need to know how to use your extinguisher now ... before a fire starts. You won't have time to read the label during an emergency.

Understand the different types of fire extinguishers ...
  • WATER - for use on Class A fires only.
  • CARBON DIOXIDE - for use on Class B and C fires.
  • CHEMICAL FOAM - for use on Class A and B fires.
  • DRY CHEMICAL - for use on Class B and C fires.
  • MULTI-PURPOSE DRY CHEMICAL - for use on Class A, B, and C fires.
  • LIQUIFIED GAS - for use on Class B and C fires, and Class A, B and C fires, dependent upon fire extinguishers classification on label.

Never use an extinguisher on a fire that it is not rated for. For example, a Class A extinguisher used on a flammable liquid or energized electrical fire would be a very dangerous mistake!

Meet the minimum requirments . . .

To meet the minimum requirements, you will need one 2-A:10-B:C. extinguisher for each 3,000 square feet or 75 feet travel distance. Hazardous occupancies must meet additional extinguisher requirements.

Read the label . . .

Your extinguisher must be rated for the fire at hand. Look for symbols that indicate your extinguishers rating.

  • an "A" is a green triangle
    for ordinary combustible materials, wood, paper, plastics & clothing.
  • a "B" is a red square for flammable liquids and gases.  
  • a "C" is a blue circle for energized electrical equipment.

Should you fight the fire?

Only fight a fire if the fire is small and confined to the immediate area where it started such as a wastebasket, cushion, small appliance, or stove. Your extinguisher is rated for the type of fire you are fighting. Proceed only if you have had training in use of the extinguisher and are confident that you can operate it effectively. If so, you must then:

  • Sound the alarm, make sure everyone has left or is leaving the building.
  • Call 9-1-1 to notify the Fire Department.

And then; if the fire is still confined to the original area ...P.A.S.S. (Pull, Aim, Squeeze and Sweep)

  • 1. Pull the safety pin.
  • 2. Aim the nozzle at the base of the fire.
  • 3. Squeeze or press the handle and sweep side to side at the base of the flame.
  • 4. Stay low to avoid breathing smoke and heat.
  • 5. Keep your exit to your back. NEVER let the fire block your exit.
  • 6. If the fire spreads or the extinguisher is ineffective GET OUT FAST and close doors behind you.

Knowing how and when to use a fire extinguisher is only one aspect of fire safety. Other key elements include:

  • Proper installation and maintenance of smoke alarms.
  • Having an escape plan and conducting regular fire drills.
  • Practicing fire safety and eliminating fire hazards at home and at work.

Remember . . .

  • If you have the slightest doubt about whether or not to fight the fire - DON'T. Instead, GET OUT, closing doors behind you to slow the spread of fire. You have one of the best fire department's standing by ready to protect you. Let the professionals do their job!
