Final answer:
Type A extinguishers should not be used on electrical fires. Electrical fires require a Type C extinguisher.
Step-by-step explanation:
Type A extinguishers are not to be used on electrical fires. They are actually meant for fires involving ordinary combustible materials such as wood, paper, cloth, and plastics. Electrical fires require a different type of extinguisher called a Type C extinguisher, which is specifically designed to suppress fires caused by electrical equipment or wiring.
