🔍 Key Concepts

• Class C electrical fires and why they’re different from other classes • The danger of energized equipment to firefighters and bystanders • The purpose and limitations of CO₂, foam, and water/fog on live electrical circuits

💭 Think About

• Before you think about what agent to spray, what hazard do you need to remove to make the situation safer? • Which option makes the other methods of extinguishing the fire safer to use afterward? • Which choices might actually be dangerous if the circuit is still energized?

✅ Before You Answer

• Identify which extinguishing agents (fog, foam, CO₂) can be hazardous or ineffective on energized electrical equipment • Decide what must be done to turn a Class C fire into a Class A/B fire so normal agents can be safely applied • Confirm which action directly removes the source of electrical energy before any discharge of extinguishing agents
