🔍 Key Concepts

• Fire classification system (A, B, C, D) and what each class represents • What is actually burning in an overloaded electric motor (insulation, wiring) • The importance of energized electrical equipment in determining fire class

💭 Think About

• Ask yourself: Is this fire primarily about wood/paper/trash, flammable liquids, energized electrical gear, or burning metal? • Consider whether the motor is still connected to power when the windings overheat and catch fire. • Think about which class of fire requires you to be cautious about using water or foam because of shock or short-circuit risk.

✅ Before You Answer

• Identify whether the equipment is electrically energized at the time of the fire. • Match the fuel involved (wire insulation and components vs. liquids vs. solids vs. metals) to the correct NFPA fire class. • Verify which fire class specifically covers electrical equipment fires in standard maritime firefighting references.
