Fire safety is crucial in every household and understanding the types of fires and the appropriate extinguishers to use can make a significant difference in preventing disaster. Fires require three elements to thrive heat, fuel and oxygen. The type of fuel involved in a fire will determine the best approach for extinguishing it. With various fire hazards from flammable liquids to cooking oils, it’s essential to know how to fight fires effectively. Here’s an overview of the common types of fires and the corresponding fire extinguishers.

Class A Fires: Organic Materials
Class A fires are common in everyday life and typically involve materials like paper, fabric, rubber, plastic, or wood. These fires often occur around campfires, candles, or wood-burning stoves. Since the fuel is carbon-based and relatively simple chemically, the solution to extinguish these fires is straightforward: water. Class A fire extinguishers use pressurized water with additives designed to cool the fire quickly and efficiently. Some extinguishers are specialized for Class A fires, while others may combine chemicals to tackle different fire types.
Class B Fires: Flammable Liquids and Gases
Class B fires are fueled by flammable liquids and gases, such as gasoline, paint, alcohol, or propane. These fires are common in workshops, garages, and sheds, where these materials are stored. Water is not effective in extinguishing Class B fires, and using it could cause the fire to spread. Instead, fire extinguishers with dry chemicals or carbon dioxide are required. While standalone Class B extinguishers are rare, you can find ABC or BC fire extinguishers that are designed to tackle a variety of fire types, including Class B fires.
Class C Fires: Electrical Fires
Electrical fires, also known as Class C fires, occur when electrical appliances or wiring catch fire. Since water conducts electricity, it’s crucial not to use water to put out electrical fires. The best fire extinguishers for these fires are ABC or BC models, which use dry chemicals or carbon dioxide to remove oxygen and heat, stopping the fire in its tracks. These extinguishers are essential in any home with electrical appliances, from space heaters to household electronics.
Class D Fires: Metal Fires
Class D fires involve metal-based materials, such as aluminum, lithium, or magnesium, which are highly flammable. These types of fires are less common in residential areas but may be found in industrial settings like welding workshops or factories. Special fire extinguishers are needed to handle Class D fires, as using the wrong extinguisher can scatter burning metal pieces and cause further danger. In these environments, using the correct fire extinguisher is critical for safety.
Class K Fires: Cooking Oil Fires
Class K fires are specific to cooking oils, such as those used in deep fryers. Unlike other flammable oils in Class B fires, cooking oil burns differently. When a Class K fire occurs, the fire extinguisher uses a chemical process called saponification, where alkaline chemicals combine with oils and fats to create a foam that cools the fire. If you frequently fry food at home, it’s recommended to keep a Class K fire extinguisher in your kitchen to ensure safety.
Choosing the Right Fire Extinguishers for Your Home
When selecting fire extinguishers for your home, it’s important to consider the specific hazards present. A combination of Class A, B, and C fire extinguishers is suitable for general household use, while garages or workshops may only need B and C fire extinguishers. For the kitchen, a Class K fire extinguisher is a must-have if you cook or fry with oil regularly.
Regardless of the fire extinguisher types you choose, make sure they are easy to use and come with clear instructions. Additionally, ensure everyone in your household knows how to operate a fire extinguisher in case of an emergency.
