In the pictograph system, which class is depicted by a flame and an electrical plug and socket?

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

Answer: (D)

The symbol shows a flame together with a plug and socket, which signals an electrical fire. That combination indicates fire in energized electrical equipment, so the appropriate class is the one for electrical fires. In practice, use a non-conductive extinguishing agent and, if safe to do so, switch off the power before fighting the fire. Water is dangerous on electrical fires because it can conduct electricity. The other kinds of fires involve different fuels (ordinary combustibles, flammable liquids, or metals) and are represented by different pictographs, so they don’t match this plug-and-flame symbol.
