Q

Which of the listed fire extinguishers would be most effective to use on a fire in a small electric motor?

🔍 Key Concepts

• Fire classes (A, B, C, D, K) and what type of material each one covers • What type of extinguisher is safest around energized electrical equipment • The properties of CO₂, foam, soda acid, and light water when used on electrical equipment

💭 Think About

• First decide what class of fire a small electric motor fire would normally be considered when the motor is still energized • Think about which extinguishers conduct electricity and which do not • Ask yourself which extinguisher works mainly by displacing oxygen rather than by applying water-based solution

✅ Before You Answer

• Verify which agents (soda acid, foam, light water) are water-based and therefore potentially conductive • Verify which extinguisher type is specifically recommended for energized electrical (Class C) fires in standard marine firefighting guidance • Double-check that the option you choose would not increase the risk of electric shock to the person using it
