Quick answer

Buy a multipurpose extinguisher with a UL Listed label and an A, B and C rating, then mount it where you can reach it on the way out. First Alert's HOME1 is rated 1-A:10-B:C and its HOME2PRO 2-A:10-B:C; the KITCHEN5 is rated 5-B:C for the kitchen. USFA says to fight a fire only when it is small and contained, everyone is alerted, and you have a clear way out.

Compare the picks and what to watch out for

Read the rating on the label

The U.S. Fire Administration (USFA) explains the classes. Class A is for ordinary combustibles like wood, paper and cloth. Class B is for flammable liquids. Class C is for energized electrical equipment, and the agent does not conduct electricity. USFA notes that multipurpose extinguishers labeled B-C or A-B-C can be used on most types of home fires.

The numbers matter too. USFA says the number before the A is a multiple of 1.25 gallons of water, and the number before the B is the area in square feet the extinguisher can put out. So a 1-A:10-B:C unit is equal to 1.25 gallons of water on a Class A fire, can put out a Class B fire up to 10 square feet, and is safe on electrical fires. A 2-A rating doubles the Class A figure to 2.5 gallons.

Look for the UL label and pick the right size

USFA says to look for a UL Listed or ULC Listed label, which shows a nationally recognized testing laboratory certified the extinguisher. It also recommends choosing the largest extinguisher you can safely and comfortably operate.

That is a trade-off in a home. A bigger unit holds more agent, but someone in the house has to be able to lift it, aim it and squeeze the lever. Try the weight of the unit before mounting it high on a wall.

Where to keep extinguishers

USFA lists easy access as the first maintenance check: be sure nothing is blocking or limiting your ability to reach the extinguisher. Mount it near an exit route, so you can grab it on the way to a fire and still have your back to a way out.

USFA says cooking is by far the leading cause of home fires. A kitchen unit should hang away from the stove, not above it. First Alert includes a mount, bracket and strap with its KITCHEN5 and a mounting bracket or hook with its HOME1 and HOME2PRO. For grease in a pan, USFA's first advice is to cover it with a lid or baking sheet and turn off the burner; see our fire blanket guide for another option.

Decide before you fight a fire

USFA gives a short checklist. Have you alerted others in the building? Has someone called the fire department? Are you physically able to use an extinguisher? Is the fire small and contained to a single object or surface, such as a pan or a wastebasket? Are you safe from the toxic smoke, with a clear escape route?

Use an extinguisher only when every answer is yes. If you are unsure, USFA says to alert others, leave the building and call 911 from a mobile or neighbor's phone. USFA also says young children and older adults should not use fire extinguishers.

Use PASS

USFA teaches the word PASS. Pull the pin, holding the extinguisher with the nozzle pointing away from you. Aim low at the base of the fire. Squeeze the lever slowly and evenly. Sweep the nozzle from side to side.

USFA encourages contacting your local fire department if you want extinguisher training. Reading the 4-step label on the unit before you need it also helps; First Alert prints 4-step instructions on a chemical resistant, waterproof label on these models.

Check it every month

USFA lists what to check: easy access, the recommended pressure level on the gauge, working parts with no damage, dents or rust on the can, hose or nozzle, and a clean outside. It notes some extinguishers need to be shaken monthly and others pressure tested every few years, and that some can be recharged while others must be replaced when pressure is low.

First Alert lists the HOME1 and HOME2PRO as rechargeable by certified professionals after use, with metal pressure gauges.
