What is the primary use of a Type C fire extinguisher?

  1. Combustible metals

  2. Flammable liquids

  3. Energized electrical equipment

  4. Ordinary combustibles

The correct answer is: Energized electrical equipment

The primary use of a Type C fire extinguisher is for fires involving energized electrical equipment. This type of extinguisher is specifically designed to safely extinguish fires that occur due to electrical hazards, such as appliances, tools, or wiring that are currently carrying an electrical current. Using a Type C extinguisher reduces the risk of electrocution and prevents further complications that would arise from using water or other extinguishers unsuitable for electrical fires. Type C extinguishers contain non-conductive agents, typically carbon dioxide or dry chemical agents, which effectively put out the fire while ensuring that the user does not inadvertently create a danger through electrical conductivity. Understanding the specific uses of fire extinquisher types is crucial for ensuring safety in environments where different materials and conditions are present.
