🔍 Key Concepts
• Fire classification: Class A, B, C, D and what burns in each
• Why electricity and water/foam can be a dangerous combination
• Which extinguishing agents are non‑conductive (e.g., CO₂, dry chemical)
💭 Think About
• First, match each fire class (A, B, C, D) with the type of fuel involved. Which class specifically mentions energized electrical equipment?
• Ask yourself: if a fire involves live electrical panels or motors, what must you avoid using, and which class of fire is designed for that?
• Think of the label you see on portable extinguishers that are safe to use on energized electrical fires—what letter do they carry?
✅ Before You Answer
• Be sure you know: Class A = ordinary combustibles, Class B = flammable liquids, Class C = electrical equipment, Class D = combustible metals before choosing
• Confirm which class requires a non‑conducting extinguishing agent because the circuit may still be energized
• Eliminate any class that deals with fuels where electricity is not the primary hazard
