🔍 Key Concepts

• Different fire classes used in maritime and industrial settings • What type of material or energy source is actually burning in an electrical short circuit • How fire extinguishers are labeled for electrical fires

💭 Think About

• First, identify what is actually on fire in a switchboard short circuit: is it ordinary combustibles, flammable liquids, electrical equipment, or burning metal? • Think about which fire class is specifically associated with energized electrical equipment and what kind of extinguishing agent is safe to use there. • Eliminate any fire classes that would normally involve things like wood, paper, fabric, gasoline, or metal shavings, and see which one remains.

✅ Before You Answer

• Confirm which fire class is defined for energized electrical equipment such as switchboards, panels, and wiring. • Verify that using water on this fire class would be unsafe because of shock or spreading the fire. • Check standard fire extinguisher markings on board (e.g., dry chemical or CO₂) to see which class symbol is used for electrical fires.
