First Alert Fire Extinguisher Ratings: Identifying Class A, B & C Fire Types

First Alert Fire Extinguishers provide an immediate solution for quickly controlling and dispersing small fires that have the potential to grow and overwhelm. Available in a variety of sizes and class types, First Alert Fire Extinguishers can safely be installed in the home or commercial setting. When selecting a fire extinguisher for your home or business, it’s important to review the extinguisher’s rating. e.g. A fire extinguisher designed to put out electrical fires may not be suitable for handling flammable fires. Let’s take a deeper look at fire rating and how they differ from one fire extinguisher to the next.

What are Fire Extinguisher Ratings?

All First Alert Fire Extinguishers feature a fire rating. These ratings are designed to reveal the types of fire that the fire extinguisher excels in putting out. This is important as fire types can vary e.g. flammable fires, combustible fires and electrical fires. First Alert Fire Extinguishers are available in the following three types:

  • Class A Fire Extinguishers are deigned to handle fires caused by ordinary combustibles. Some of the leading culprits that cause these fires would be combustible materials such as: firewood, cloth, plastic and paper. It is recommended that Class A Fire Extinguishers be setup near fireplaces and other areas that may pose a similar threat.

  • Class B Fire Extinguishers are used to combat fires caused by flammable liquids and combustible gas. These fires are capable of spreading extremely fast and can be attributed to gasoline, grease, oil and paints. Class B Fire Extinguishers should be installed where any of these are present e.g. garages, kitchens and sheds.

  • Class C Fire Extinguishers excel in putting out electrical fires. It should be noted that water cannot be used to extinguish an electrical fire. This will in fact result in exposing the surrounding area to electrocution. Electrical fires are commonly caused by electrical equipment, paneling, wiring and circuit breakers. Class C Fire Extinguishers should be placed in areas where electrical equipment/machinery is used and wherever electrical wiring is setup.

Which Fire Extinguisher is Right for me?

When searching for a residential/home fire extinguisher, it would be wise to consider one that covers multiple classes as possible. All First Alert Fire Extinguishers available online at the First Alert Store are multi-rated, meaning they can handle two or more types of fire.

For all around three class protection, there’s the First Alert Rechargeable Home Fire Extinguisher that can be used on Class A, B & C fires. It is recommended that fire extinguishers be installed on every level of the home. When used with First Alert Smoke and Fire Detectors, First Alert Fire Extinguishers are capable of adding significant fire protection to any home.
