In a fire in an elevator machine room, extinguishers should be used for which class fires?

Explanation:
Fires in an elevator machine room are classified as electrical fires because the equipment there is energized—think motors, control panels, and wiring. The key safety point is to use extinguishing agents that won’t conduct electricity, such as CO2, dry chemical, or other clean-agent extinguishers. Water or water-based methods are avoided on energized electrical fires because they can cause electrical shock and spread the fire by conducting electricity. If it’s safe to do so, shut off power, then use the appropriate extinguisher for electrical fires. In this context, the best answer is electrical fires.
