Microwave Safety 101

In many Pittsburgh households, the microwave is more than just a kitchen convenience—it’s a daily go-to for busy mornings, after-school snacks, and late-night leftovers. For kids, it’s often the first appliance they learn to use independently. But even this trusty tool comes with safety must-knows that every homeowner—and future homeowner—should keep in mind.

Whether you’re settling into a new home or helping your kids gain kitchen confidence, here are some microwave safety basics to keep your household safe:

  • Liquids can superheat without boiling visibly and suddenly erupt, causing scald burns — the most common microwave injury. Heat liquids in 30 to 60-second intervals and check the temperature. Use oven mitts when removing hot items.
  • If the door doesn’t shut tightly, don’t use it.
  • Remove food from non-microwave-safe packaging, like Styrofoam trays or some plastic containers, before heating to avoid chemical leaching.
  • Never put metal, like foil or utensils, in the microwave, which can cause a fire or damage the microwave.
  • Sealed containers may explode. Instead, use microwave-safe plastic wrap (with holes for steam to escape) to prevent splattering, cook more evenly, and retain moisture.
  • Plug directly into outlets.
  • Make sure kids know that they should not turn on an empty microwave, which could start a fire or damage it.
  • Open food slowly after heating, as the steam can cause burns.
  • Clean the microwave regularly.
  • If a fire starts inside the microwave, leave the door closed, turn it off, and unplug it.

It’s a good idea to review the manufacturer’s instructions periodically and register the microwave to be notified of any recalls or safety notices.
