The selection of a Type C fire extinguisher for use on electrical fires is correct because these extinguishers are specifically designed for fires that involve energized electrical equipment. They typically contain non-conductive agents that can put out the fire without conducting electricity, thus ensuring the safety of the user and preventing further electrical hazards.

Type C extinguishers usually contain dry chemical agents, such as sodium bicarbonate or potassium bicarbonate, which are effective in smothering the flames caused by electrical fires. Understanding that types A, B, and D extinguishers are not suitable for electrical fires is important: A extinguishers tackle ordinary combustibles, B extinguishers are for flammable liquids, and D extinguishers handle combustible metals, none of which address the unique hazards of fires involving live electrical circuits. Therefore, the appropriate choice for electrical fires is indeed the Type C extinguisher, ensuring safe and effective fire suppression.
