✅ 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
