🔍 Key Concepts

• Class "C" fires involve energized electrical equipment • The primary danger when applying an extinguishing agent to live electrical equipment • How different extinguishing agents (water, foam, dry chemical, CO₂) interact with electricity

💭 Think About

• Think about what could happen if the extinguishing agent conducted electricity while the equipment is still energized • Which property of an extinguishing agent directly protects the firefighter from electrical shock in a Class "C" fire? • For Class "C" fires, which concern comes BEFORE cooling the fire or preventing rekindling?

✅ Before You Answer

• Confirm what types of materials/extinguishing agents MUST be avoided on energized electrical equipment (water, foam) • Identify the special requirement for agents used on energized electrical fires • Ask yourself: Which option, if missing, would make the agent completely unsafe to use on Class "C" fires, no matter how well it cools or prevents rekindling?
