The use of a "Class C" hand-held fire extinguisher would be preferable **when the fire involves electrical equipment**. Class C extinguishers are specifically designed to handle fires that involve electrical hazards, as they typically use non-conductive agents to suppress the fire without risking electric shock. It's important to note that: - A "Class A" extinguisher is used for ordinary combustible materials like wood, paper, and cloth. - Using a Class A extinguisher on a Class C fire (involving electrical equipment) could be dangerous as water (a common agent in Class A extinguishers) is conductive. Thus, always choose a Class C extinguisher for electrical fires to ensure safety and effectiveness.
