1, avoid using metal utensils. When heating things in a microwave oven, the utensils for holding food must be non-metallic materials, such as glass, ceramics and high-temperature resistant plastics. If it is a metal container for holding food, the metal container will reflect microwave after being electrified, which will interfere with the normal work of C in the oven, produce high frequency and short wave and damage the microwave oven.

2. Avoid directly heating frozen food. Frozen food cannot be directly heated by microwave oven. Frozen food should be thawed first, and then heated and cooked to avoid the phenomenon that cooked food has different degrees of maturity inside and outside. Pay attention to the size and thickness of food, and don't differ too much.

3. Avoid heating food in a closed container. In the use of microwave ovens, do not use closed containers to hold food, because the heat generated by heating food in closed containers is not easy to dissipate, which will increase the pressure in the containers and easily lead to explosion accidents. In addition, during the heating process in Weibo, stay away from the microwave oven for a period of time to prevent accidents and injuries to yourself.

4. Avoid heating food for a long time. The food is heated in the microwave oven. If you forget to take it out for more than 2 hours, you should throw it away to avoid food poisoning.

These are the precautions for using microwave ovens. I hope it helps you.
