Which class is associated with Live Electrical equipment?

• A. Class E
• B. Class B
• C. Class A
• D. Class C

Answer: (A)

When dealing with fires, the label on the class tells you what kind of hazard you’re fighting and what extinguishing method is safest. A fire involving live electrical equipment is treated specially because electricity is still present, so you must use an extinguishing agent that won’t conduct electricity and won’t create a shock risk. That’s why the classification for this scenario is Class E. It specifically covers fires in energized electrical equipment, guiding you to use safe, non-conductive extinguishing media and, if possible, to switch off the power before or while applying the agent. The other classes describe different hazards—ordinary combustibles or flammable liquids—and don’t apply to a live electrical fire, so they aren’t the correct match.
