Q

Which of the listed fire extinguishers is recommended for use on an electrical switchboard fire?

🔍 Key Concepts

• Electrical fires (Class C) and what makes an extinguisher safe or unsafe around live circuits • Differences between CO₂, ABC dry chemical, and foam extinguishers • Effect of conductivity and residue on sensitive electrical equipment

💭 Think About

• Which extinguisher type does not conduct electricity and does not leave a residue that could damage or short out electrical equipment? • Would using a water-based or foam agent near live electrical parts be a concern, even if CO₂ is the propellant? • How is an extinguisher specifically labeled or rated for Class C (electrical) fires, and which of these best fits that description for a switchboard?

✅ Before You Answer

• Confirm which agents are specifically rated for Class C (electrical) fires • Check whether the agent leaves a corrosive or conductive residue on sensitive equipment like switchboards • Verify if any option involves a water or foam solution contacting energized parts, regardless of how it is propelled
