Hot plates and computers belong to which fire class?

Explanation:
Fires tied to electrical equipment are categorized as electrical fires. Hot plates and computers are electrical devices, so a fire involving them is driven by electricity in addition to any fuel they contain. This makes the situation fall under Class C. It’s distinct from Class A (ordinary combustibles like wood and paper), Class B (flammable liquids), and Class D (reactive metals). In practice, fight electrical fires with non-conductive extinguishing media and, if safe to do so, disconnect power first; avoid using water on energized electrical fires because it can conduct electricity and pose a shock risk.
