What Type of Fire Extinguishers Do You Need For Your Business?

Understanding Which Fire Extinguishers Are Right For You

When it comes to protecting your business from fire hazards, knowing the right type of fire extinguisher is crucial. Not all fires are the same, and using the wrong extinguisher can be ineffective or even dangerous. This blog will guide you through the different types of fire extinguishers, their uses, and more.

Types of Fire Extinguishers and Their Applications

1. Water (Class A): Primarily used for fires involving common combustibles like wood, paper, and textiles, water extinguishers are the simplest form of firefighting tools. They work by cooling the burning materials below their ignition temperature but are not suitable for grease, oil, electrical fires, or flammable liquids because water can spread the fire or conduct electricity. They are commonly found in schools, offices, and warehouses where such materials are prevalent.
2. Carbon Dioxide (CO2) (Class B & C): CO2 extinguishers are effective against flammable liquids like gasoline, solvents, and grease fires, making them ideal for locations where such materials are handled, including mechanical rooms, kitchens, and laboratories. They extinguish fire by displacing oxygen and cooling the fuel. However, they’re not recommended for Class A fires as they can’t effectively penetrate the materials to reduce their temperature. It’s also worth noting that CO2 can pose a risk of frostbite if not handled properly and does not leave a residue, which makes cleanup easier.
3. Dry Chemical (Class A, B, & C): Offering versatility, dry chemical extinguishers are suitable for a broad range of fires, making them a popular choice in various settings, including offices and industrial locations. They work by interrupting the chemical reaction of fire. Monoammonium phosphate-based dry chemical extinguishers can leave a sticky residue that may cause damage to electrical appliances or machinery, thus requiring a clean-up post-use.
4. Wet Chemical (Class K): Specifically designed to combat kitchen fires involving cooking oils and fats, wet chemical extinguishers are a must-have in commercial kitchens. They work by creating a foam layer over the burning oil and cooling the fire’s temperature, preventing re-ignition. Although highly effective for Class K fires, they are not suitable for other fire classes due to their specific chemical composition designed for fats and oils.

Each type of fire extinguisher uses a specific method to combat fires: Water extinguishers cool the fire, carbon dioxide displaces oxygen, dry chemical extinguishers interrupt the fire’s chemical reaction, and wet chemical extinguishers create a barrier between the fuel and the fire. These methods target different classes of fires, from ordinary combustibles to flammable liquids and electrical fires, ensuring that there’s a specialized solution for various fire scenarios encountered in workplaces.

How to Know What Type of Fire Extinguisher I Have?

To identify the type of fire extinguisher you have, check the label or the body of the extinguisher. It will typically have symbols or letters (A, B, C, D, K) indicating the classes of fire it’s designed to combat, and possibly a description of its extinguishing agent (water, CO2, dry chemical, wet chemical).

Additionally, the color and shape of the extinguisher can give clues, but the most reliable information comes directly from the labeling on the device.
