How to Practice Microwave Safety

Instructions

  • Step 1: Follow the manufacturer’s instructions Follow the manufacturer’s instruction manual for operating procedures and safety precautions for your oven model.
  • TIP: Never operate the oven if the door does not close properly, or if the door, latch, hinge, or sealing surfaces have been damaged.
  • Step 2: Use the microwave oven appropriately Use the microwave only for defrosting, heating, and cooking food. Other uses may lead to a fire.
  • Step 3: Use microwave-safe containers Use microwave-safe containers including heat-safe glass, glass-ceramic, china, pottery without metal, and plastic containers labeled “Microwave-safe.” Use paper for short heating periods.
  • TIP: Microwave energy passes through these containers and heats the food inside. But containers may still become hot if the food gives off a lot of heat.
  • Step 4: Avoid containers with metal Never use metal, including pottery or glass with metallic glaze, in the oven.
  • Step 5: Do not overheat liquids Do not overheat liquids such as water, coffee or tea in the oven. They may boil over after you remove them.
  • TIP: Stir liquids before and halfway through heating. Leave the container in the oven for a short while before removing it.
  • Step 6: Exercise caution with baby foods Heat baby food in a dish, not in the jar. When heating a bottle, remove the nipple to avoid trapping steam. After heating, shake the bottle to achieve a uniform temperature.
  • FACT: Did you know? In 1947, microwave ovens were the size of refrigerators and cost between $2,000 and $3,000.
