Microwave Safety: Beware of Potential Dangers
To be microwave safe, follow these microwave safety tips to help reduce home fires and serious injuries.
Microwave safety
While microwave ovens offer quick, convenient cooking, they can also be dangerous if not used carefully. According to a study published in 2023 by the National Fire Protection Association, 6,544 microwave- related fires occurred between 2017-2021. Over 90% of American households have at least one microwave, making many households susceptible to microwave related house fires if not properly used.
Microwave injuries
- Spills are the most common cause of injuries.
- The most common types of injuries were burns to the fingers and hands.
- Children are more likely to burn their face, head or neck than adults.
Erupted hot water phenomenon
This phenomenon happens when water heated beyond 212 degrees Fahrenheit in a clean cup or bowl shows no signs of boiling but explodes if disturbed. To help reduce this risk:
- Use dishes with sloped sides
- Stir in sugar, instant coffee or soup mixes before microwaving
- Leave a microwaveable spoon in liquids while heating to break up the surface tension
- If you need to boil water, consider doing so on the stove with a pot or kettle
Fire and ice
To eliminate hot spots in microwaved foods:
- Rotate the dish one-quarter to one-half a turn midway through cooking
- Stir foods before eating
Hot, hot, hot!
The steam inside microwaved containers and popcorn bags can exceed 180 degrees Fahrenheit. Use caution when cooking with or handling these items.
- Use vented containers
- Open containers away from your face
- Let containers cool for 1 to 2 minutes before opening
- Use oven mitts or potholders when removing items
