🔍 Key Concepts

• Fire classes (A, B, C, D, K) and what fuel/source each one represents • Which class covers energized electrical equipment such as panels, motors, and wiring • Types of extinguishing agents used on ships for electrical fires (e.g., non‑conductive agents)

💭 Think About

• Ask yourself: which fire class is specifically linked to fires where the electricity is still ON (energized circuits)? • Think about why you would NOT want to use water or foam directly on an electrical panel—what property must the extinguishing medium have? • Match that property to the common fixed or portable extinguishing agents you see listed in marine fire manuals or on equipment labels.

✅ Before You Answer

• Verify which fire class corresponds to energized electrical equipment (short circuits, switchboards, control panels). • Check which extinguishing medium is non‑conductive and safe around live electrical circuits. • Confirm that the agent you choose is actually approved/commonly used on Class C (electrical) fires in marine applications.
