Which type of fire extinguisher should you use on electrical fires?

• A. Water-based extinguishers
• B. Foam extinguishers
• C. Dry powder extinguishers
• D. Chemical extinguishers

Answer: (C)

For electrical fires, using a fire extinguisher that is effective against electrically charged materials is crucial to ensure safety and effectiveness. Dry powder extinguishers are specifically designed for this purpose. They can put out fires caused by electrical equipment, as the powder can smother the flames without conducting electricity, thus preventing electrical shock. When equipment or appliances that might be energized are involved in a fire, using water or foam extinguishers is dangerous. Water is a conductor of electricity and can create a risk of electric shock or electrocution. Foam extinguishers are also not suitable for electrical fires due to similar conductivity issues and their effectiveness in dealing with flammable liquids rather than electrical hazards. Chemical extinguishers, while they may be effective for certain types of fires, are not the standard choice for electrical fires. Dry powder extinguishers, such as those rated for Class C fires, which specifically include electrical fires, are the recommended option because they effectively interrupt the chemical reaction that fuels the fire without posing a risk of electric conduction.
