how to use a fire extinguisher

After smoke detectors, fire extinguishers might be your best defense in the event of a fire in your home or office. Used properly, on the right type of fire, they can prevent the spread of flames, reduce smoke and fire damage, and maybe even save your life. Learning how to use a fire extinguisher can save a building or even your life in an emergency situation.

First, fire extinguishers have limits. They are intended for use on small, contained fires. A fire can quickly get out of control, so call 911 right away, even if you think you can or have put the fire out. Always fight the fire with your back to an unobstructed exit, and if the room is filling with smoke, or the flames are taller than you, get out. Make sure you have a fire escape plan before a fire emergency occurs.

Make Sure You Use the Right Extinguisher on the Right Type of Fire.

Fire extinguishers can prevent a small fire from becoming a large fire. It’s important to be familiar with the different types of extinguishers so you know which one to use, and when to use it. Fire extinguishers can be classified as type A, B, C, D or some combination of these letters.     Class A fire extinguishers are used to put out fires that started with solid organic materials like wood, paper, or cardboard.     Class B fire extinguishers are used to put out fires linked to flammable liquids or gases like kerosene or gasoline.     Class C fire extinguishers are used to put out electrical fires.

Most experts recommend purchasing multipurpose class A/B/C fire extinguishers for home use. Class A/B/C extinguishers use mono ammonium phosphate which can be used to extinguish paper/wood fires, flammable liquid fires, and electrical fires. Buy the largest one you can comfortably handle and keep it fully charged and pressurized.

Put Your Extinguishers in the Right Places.

You should have at least one fire extinguisher on each level of your home. They should be kept out of reach of children, but easily accessible for adults. Keep them where a fire is most likely to start and near an exit. The kitchen and the garage are common starting places for house fires. You should also keep a fire extinguisher in the room if you have a wood-burning fireplace.

Knowing How to Use Your Fire Extinguisher.

So now you understand the limits and benefits of fire extinguishers. You have bought and strategically placed them around your house. But do you know how to use one? According to FEMA, most Americans don’t know how to use a fire extinguisher.  You don’t want to be Googling directions or looking up a Youtube video while your stovetop becomes a blazing inferno.

Just remember to PASS. Pull, Aim, Squeeze, and Sweep.

Pull the pin.

Aim the extinguisher at the base of the fire.

Squeeze the trigger carefully. The contents are under pressure so squeeze with control.

Sweep the flames out. Continue aiming at the base of the fire and use a sweeping back and forth motion to extinguish the fire.


Whew! You put the fire out. Keep an eye on ground zero (the origin of the fire) while you wait for the fire department to arrive. Tiny embers have a sneaky way of re-igniting. Be sure to get your fire extinguisher recharged and re-pressurized right away; or dispose of and replace a disposable one. As the saying goes, an ounce of prevention is worth a pound of cure.
