What type of extinguisher is used for electrical fires?

The correct choice is Class C extinguishers, which are specifically designed to tackle electrical fires. These extinguishers contain non-conductive extinguishing agents that effectively put out fires involving electrical equipment and appliances without posing a risk of electrical shock to the user.

Class C fires can involve live electrical wires, circuit boards, or other energized electrical components. Using the wrong type of extinguisher—like those meant for ordinary combustibles or flammable liquids—can be hazardous since these agents may conduct electricity and lead to severe injury or further incidents.

In practical terms, a Class C extinguisher typically utilizes agents such as carbon dioxide (CO2) or dry chemical substances, which deprive the fire of oxygen or interrupt the chemical reaction, ensuring safe and effective firefighting. Knowing the correct type of extinguisher to use in these situations is crucial for ensuring safety and effective emergency response.
