The idea that you need to stay away from the microwave while it is running is not an "old wives' tale." While modern microwave ovens are generally safe to use when used properly, it is still recommended to exercise caution and follow certain safety guidelines.
Here are a few reasons why it's advisable to stay away from the microwave while it is running:
Potential for burns: Microwaves heat food by generating heat within the food itself. However, the container or plate holding the food can become hot during the cooking process. If you remove the food or container immediately after microwaving, you may accidentally touch a hot surface and burn yourself.
Steam and hot food: When you open the microwave door after cooking, steam and hot food vapors can escape, which may cause burns if they come into contact with your skin or face. It's a good practice to allow food to cool for a short period before removing it from the microwave.
Accidental spills: Moving hot containers or plates immediately after microwaving can increase the risk of accidental spills, which can cause burns.
While it's not necessary to completely avoid the microwave area, it is recommended to maintain a safe distance and follow basic safety precautions. Give the food a few moments to cool down, use oven mitts or heat-resistant gloves when handling hot containers, and be cautious of steam or hot vapors when opening the microwave door.
Additionally, always follow the specific safety instructions provided by the microwave manufacturer and ensure the microwave is in good working condition, without any damaged or faulty parts, to ensure your safety during use.
