You’ve Seen Fire Extinguishers—Now Meet the Class C That Defies Expectation When it comes to fire safety, most people immediately picture ABC-rated extinguishers—versatile tools designed for ordinary electrical, flammable liquid, and ordinary solid fuel fires. But there’s a hidden hero in fire suppression you might never expect: the Class C fire extinguisher. Unlike its common ABC counterparts, a Class C extinguisher specializes in electrical fires, specifically those involving energized electrical equipment. ### What Exactly Is a Class C Fire? Class C fires occur when electrical devices—such as power tools, wiring, circuit breakers, or electrical panels—catch fire. Since electricity conducts through metal and can arc, using any water-based or even some dry chemical extinguishers near electrical sources is extremely dangerous. That’s where Class C extinguishers come in. These devices safely interrupt electrical current and suppress flames without risking electrocution.
