ExtinguishersWhen it comes to business safety, fire protection isn’t just a precaution—it’s a necessity. But not all fires are created equal, and neither are fire extinguishers. From high-tech data centers to fast-paced commercial kitchens, choosing the right fire extinguisher can mean the difference between minor damage and major disaster.
In this guide, we break down how to choose the right extinguisher for your business based on environment, industry, and specific fire hazards—because using the wrong type could actually worsen a fire.
Why Matching the Right Extinguisher to the Risk Matters
According to the National Fire Protection Association (NFPA), U.S. fire departments respond to more than 100,000 non-residential fires annually, causing an estimated $3.3 billion in property damage each year【source: NFPA, 2023 Fire Loss in the U.S. report】. Proper fire extinguisher placement and type can reduce damage, slow spread, and even prevent injuries.
The Five Main Classes of Fires—and the Extinguishers That Tackle Them
Before picking an extinguisher, know the type of fire you’re likely to face. Fires are categorized by the materials fueling them:
- Class A: Common combustibles like wood, paper, cloth
- Class B: Flammable liquids like gasoline, oil, and solvents
- Class C: Electrical equipment fires
- Class D: Combustible metals (rare in most industries)
- Class K: Cooking oils and fats, common in commercial kitchens
