Best fire extinguisher

Which fire extinguishers are best?

The risk of fires breaking out is always present. Basic household safety recommends that all homes contain at least one fire extinguisher with many safety experts recommending having a fire extinguisher in most rooms of homes, especially if the home is large. Fire extinguishers come in more forms than one which can make it hard to know which extinguisher is right.

One of the best fire extinguishers is the Amerex B402 5 Pound ABC Dry Chemical Class A B C Fire Extinguisher. This fire extinguisher is rated to handle almost any source of fire.

What to know before you buy a fire extinguisher

Fire extinguisher classes

Fire extinguishers are separated into five classes with each class covering certain types and sources of fires. Never use a fire extinguisher against a fire it isn’t rated for as you could accelerate the fire instead.

• Class A: Class A covers fires sourced from solids like wood. Its image is that of a burning trash can and/or campfire.
• Class B: Class B covers fires sourced from liquids and gasses like oil and propane. Its image is that of a burning gas canister.
• Class C: Class C covers fires sourced from electricity like shorted wire. Its image is that of a burning plug.
• Class D: Class D covers fires sourced from metals like aluminum. Its image is that of a burning gear. These fires are unlikely in residences
• Class K: Class K covers fires sourced from cooking oil. Its image is that of a burning pan. These extinguishers are usually found in commercial kitchens as residences can use a class B extinguisher for their cooking fires.

What to look for in a quality fire extinguisher

Extinguishing materials

Each class of fire extinguisher uses different extinguishing materials, which target the kinds of fires those classes are rated to fight.

• Carbon dioxide: Carbon dioxide is designed to remove heat and oxygen from fires. It’s typically used in class B and C models.
• Dry chemical: Dry chemicals are the most common residential-intended material found in fire extinguishers. They’re found in classes A through C.
• Wet chemical: Wet chemicals are typically found in class K fire extinguishers. In rare cases, they are also found in class A models.
• Dry powder: Dry powder is largely restricted to industrial fires covered in class D extinguishers.
• Liquified gas: Liquified gas is less commonly found in fire extinguishers. It is typically used in classes B and C, and rarely found in class A models.
• Foam: Foam is as equally common as dry chemical, especially for use in residencies. Foam is found in classes A through C.
• Water: Water is rarely used outside of the high pressure dispensers of fire departments, though in rare cases it can be found mixed with foam in class A fire extinguishers.

How much you can expect to spend on a fire extinguisher

FIre extinguisher prices typically coincide with the amount of extinguishing product they contain. Miniature fire extinguishers can cost as little as $20, while the largest capacities can hit up to $100. The average cost of a fire extinguisher is $45.

Fire extinguisher FAQ

How do I maintain my fire extinguisher?

A. Fire extinguishers should be examined for signs of defects at minimum once a year. Each fire extinguisher has its own set of maintenance needs that should be clearly listed on the canister. Common areas of concern for fire extinguishers are the valve, nozzle and safety pins that prevent accidental discharge. All extinguishers should have their pressure examined as pressure can leak out over time, with some needing to be shaken every three months to maintain their pressure. You can also contact your local fire department to see if they can inspect your fire extinguisher for you.

What size fire extinguisher should I buy?

A. The appropriate size fire extinguisher depends on what room of the home or other areas it’s supposed to be able to cover. Large fire extinguishers are designed to put out larger fires that may have been burning for a few minutes, like in a garage. Medium canisters should be enough to handle fires found quickly in commonly accessed areas, while small canisters are typically meant to cover cooking- or car-related fires.
