Let me start off by saying everyone should have multiple ABC rated fire extinguishers throughout their home for safety. A fire extinguisher is something that you hopefully never have to use, but can save your home or life in the event of a fire.

What does the A B C stand for?

A – Trash, Wood, and Paper

Monoammonium phosphate is the main ingredient in the fire extinguisher that will help smother this type of fire.

B – Flammable Liquids

Monoammonium phosphate and sodium bicarbonate work together to help extinguish a fire involving flammable liquids.

C – Electrical Equipment

Again, both Monoammonium phosphate and sodium bicarbonate work together to help extinguish a fire involving electrical components.

– How to use a fire extinguisher –

The recommended method is the P.A.S.S. technique. Below is the step by step technique directly from OSHA:


  1. PULL
    … Pull the pin. This will also break the tamper seal.
  2. AIM… Aim low, pointing the extinguisher nozzle (or its horn or hose) at the base of the fire.
  3. NOTE: Do not touch the plastic discharge horn on CO2 extinguishers, it gets very cold and may damage skin.

  4. SQUEEZE… Squeeze the handle to release the extinguishing agent.
  5. SWEEP… Sweep from side to side at the base of the fire until it appears to be out. Watch the area. If the fire re-ignites, repeat steps 2 – 4.

If you have the slightest doubt about your ability to fight a fire….EVACUATE IMMEDIATELY!

Hopefully this blog gives you a better understanding of fire extinguishers and the absolute necessity of having them in your home. Be sure to check them regularly to ensure they are charged and ready in case of emergency as well.
