What does the "C" in Class C fire extinguisher refer to?

The "C" in Class C fire extinguisher specifically refers to electrical fires. This classification is important because electrical fires can occur in situations involving energized electrical equipment, wiring, or appliances. Using the correct type of fire extinguisher is crucial for safety; for instance, using a water-based extinguisher on an electrical fire can lead to electrocution. Class C extinguishers are designed with agents that can effectively put out fires caused by this type of ignition without posing additional risks.

Understanding fire classifications helps ensure that appropriate extinguishing methods are employed, which is vital for safety in environments where electrical hazards are present.
