🔍 Key Concepts

• Class C fires involve energized electrical equipment • Why water or foam can be dangerous on certain fires • Key safety property of agents used around live electricity

💭 Think About

• Ask yourself: If the equipment is still energized, what property must the agent have so it does NOT create a path for electric current through the firefighter? • Which choice directly relates to electrical safety, not just putting out flames? • Which options are generally nice-to-have for many fires, and which ONE is absolutely critical when electricity is involved?

✅ Before You Answer

• Confirm what makes Class C different from Class A and B (energized electrical circuits). • Eliminate any option that does not clearly address electrical shock hazard. • Think about why you would NOT want to use plain water from a hose line on a Class C fire. What property is missing?
