40 Hour Property and Building Inspection Practice Test

Before operating a microwave oven, which of the following should be checked?

1. Only the electrical connections

2. Only the door seals

3. Broken door hinges, seals and broken glass; damaged case; outlet not grounded

4. Only the exterior case

The correct answer is: Broken door hinges, seals and broken glass; damaged case; outlet not grounded

In assessing the safety and functionality of a microwave oven before operation, it's crucial to check multiple components to ensure that everything is in proper working order. The correct choice highlights several key areas requiring attention: 1. **Broken door hinges**: Ensuring the door hinges are intact is vital, as a malfunctioning door could prevent the oven from closing properly. If the door does not seal, it could lead to microwave radiation escaping, posing safety risks. 2. **Seals**: The door seals are crucial for preventing microwave radiation from leaking out during operation. Damaged or worn seals undermine the safety of the appliance, therefore checking them is necessary. 3. **Broken glass**: A damaged glass plate or door can inhibit the proper operation of the microwave and can also be a safety hazard. Shattered pieces of glass could lead to injuries. 4. **Damaged case**: A compromised exterior can affect the microwave's functionality and interfere with safety standards, as cracks or openings may allow microwave energy to escape. 5. **Outlet grounding**: Ensuring that the outlet is grounded is essential for electrical safety. A properly grounded outlet helps prevent electric shocks or electrical fires when operating the appliance. By verifying the condition of all these elements, users can confidently
