Residential Fire Extinguishers

Why it matters

Extinguishers can help stop a very small fire, but using one at the wrong time can trap you in toxic smoke or delay your escape

What to know

Use a fire extinguisher only when the fire is small and contained, you are safe from smoke, someone has called 911, and you have a clear escape route

If you answer “no” to any of those, quickly get out, close doors behind you if it is safe to do so, and call 911 from outside.
Just like smoke and carbon monoxide alarms, fire extinguishers do not last forever. Always read your manufacturer’s user manual so you know exactly what maintenance your specific extinguisher needs, when it expires, and how to properly store it.

If it is safe to use an extinguisher, remember the PASS method:

  • Pull the pin
  • Aim low at the base of the fire
  • Squeeze the lever
  • Sweep side-to-side

There are different types of fire extinguishers because different types of materials catch fire. Be sure the extinguisher you use is the correct one
An “ABC” extinguisher is the most common “all‑purpose” extinguisher for homes and offices. It can be used on:

  • Class A: Ordinary combustibles (wood, paper, cloth, trash, many plastics)
  • Class B: Flammable liquids and gases (gasoline, oil, grease, paint, solvents)
  • Class C: Energized electrical equipment (wiring, breaker panels, appliances, tools)

Do this now

  • Know your extinguisher
    Read the manufacturer’s user manual to check your specific model’s expiration date and learn how to maintain it
  • Inspect monthly
    Check the pressure gauge, pin, and hose once a month, and look for damage or rust
  • Check placement
    Place an extinguisher where a small fire could start (often the kitchen) and keep it unblocked. Never store over a stove or where it’s hard to reach or forgotten about.
  • Learn PASS
    Teach adults the PASS method and show them where the extinguisher is

Don’t

Don’t fight a spreading fire. Don’t try to fight a fire that is spreading, smoky, or between you and your exit. Get out quickly and call 911 from outside instead.
