🔍 Key Concepts
• Class "C" fires involve energized electrical equipment and require non-conductive agents
• On the fire control plan, each numbered symbol represents a specific type of extinguisher or installation (CO₂, foam, water, hose reel, etc.)
• Using water or foam directly on energized electrical gear is generally unsafe, while CO₂ or certain dry chemicals are preferred
đź’ Think About
• First, from basic fire theory, decide which general extinguishing agent type is safest for live electrical equipment and why
• Then, carefully inspect the illustration and match each answer choice number (26, 36, 47, 56) with the type of extinguisher or system it represents
• Eliminate any option that would apply water or foam directly to energized electrical parts
âś… Before You Answer
• Confirm which symbol number in the illustration clearly shows a CO₂ or other non‑conductive agent extinguisher, as opposed to water or foam
• Verify that any symbol suggesting a hose or hydrant is not chosen, since those usually imply water systems
• Double‑check the small label letters on the extinguisher symbols (such as CO₂, P, W, F) to ensure you are matching the correct agent to a Class "C" fire
