Q

Which of the listed classes of fire would apply to a main switchboard fire?

🔍 Key Concepts

• Fire classification by type of fuel involved (ordinary combustibles, flammable liquids, electrical equipment, combustible metals) • What equipment is found in a ship’s main switchboard (high-voltage energized electrical components) • Why certain extinguishers cannot be safely used on energized electrical fires

💭 Think About

• Ask yourself: is the main switchboard primarily metal structure, electrical equipment under voltage, or a fuel source like oil or paper? • Which fire class is specifically defined for energized electrical equipment, not just what’s burning but what is supplying the energy? • Think about which extinguishing agents are recommended or prohibited for a live switchboard fire and which class those agents are designed for.

✅ Before You Answer

• Identify what a main switchboard on a vessel actually does and what type of hazard it mainly represents when energized • Match that hazard to the correct fire class definition used in marine firefighting training (A, B, C, or D) • Verify which class would avoid conducting electricity to the firefighter when used on an energized panel
