What kind of screwdriver was Joe required to use while working on the microwave oven?

In working on electrical appliances like a microwave oven, safety is paramount, particularly when dealing with high-voltage components. An insulated screwdriver is designed with a protective coating that prevents electrical current from passing through to the user, minimizing the risk of electric shock while working on live circuits. This kind of tool is essential for technicians when servicing electrical equipment, ensuring they can safely interact with electrical components without risking their safety.

Using an insulated screwdriver allows technicians to maintain proper safety protocol and reduces the likelihood of accidents in situations where they might inadvertently come into contact with energized parts. For this reason, it is the correct choice for servicing a microwave oven, which contains elements like the magnetron and high-voltage capacitors that can pose significant hazards if not handled carefully.
