Power Outage Tips and Tricks

Stay away from windows

  • Keep items away from windows to minimize damage from downed power lines.

Keep the refrigerator temp at 40 degrees Fahrenheit

  • A full freezer can keep food cold for about 48 hours if the door remains closed. Store food and water at a temperature below 40 degrees to maintain freshness.

Food Storage Guidelines During a Power Outage

Know Your Circuit Breaker

Fill Your Gas Tank

  • If you have a vehicle, keep the gas tank filled up. Gas stations may be closed or inaccessible during outages.

Use Solar-Powered Garden Lights as Flashlights

Create an Emergency Cooler with Your Washing Machine

  • Fill your washing machine with ice and store your perishable items, such as milk, eggs, cheese, and anything else that needs to be cold.
  • The airtight seal of the washing machine will keep the items fresh for a period of time.
  • When the ice melts, the water will drain out of the washer as it usually does.

Keep Makeshift Ice Packs in the Freezer

  • Fill ziplock baggies with water.
  • Keep these in the freezer.
  • Use these as ice packs during a power outage, in case of injuries or illness.

Avoid Open Fire

  • Traditional candles can pose big fire hazards. Choose a battery-operated candle instead to reduce risks.

Avoid Carbon Monoxide Poisoning

  • Never use gas stoves or charcoal grills indoors for heating or cooking.

Power Outage Tips for Your Refrigerator 

  • Keep the Refrigerator and Freezer Closed: Keep the doors closed as much as possible. An unopened refrigerator can keep food cold for about four hours, while a full freezer can maintain its temperature for up to 48 hours (24 hours if half full) if the door remains closed.
  • Add Ice: If you anticipate a long outage, consider placing blocks of ice in the refrigerator or freezer to help keep the temperature down.
  • Use a Thermometer to Monitor Food: Keep an appliance thermometer in both the refrigerator and freezer. After the power is restored, check the temperatures:
    • Refrigerator: Should be at or below 40°F (4°C).
    • Freezer: Should be at or below 0°F (-18°C) .
  • Follow the Two-Hour Rule and Throw Away Unsafe Food: Perishable food that has been above 40°F for more than two hours should be discarded to prevent foodborne illness. If the power is out for more than 24 hours, throw away perishables like meat, dairy, and leftovers.
  • Put Perishables in Coolers: For outages lasting longer than a few hours, consider transferring perishable items to a cooler filled with ice to keep them cold.
  • Inspect Food When the Power Comes Back On: Once power is restored, check all food for signs of spoilage, such as off smells, unusual textures, or discoloration. When in doubt, throw it out to avoid health risks.

Power Outage Tip for Home Appliances

  • Unplug Sensitive Devices: Disconnect sensitive electronics such as computers, televisions, game consoles, and microwaves. This helps prevent damage from potential power surges when electricity is restored.
  • Turn Off Appliances: Turn off and unplug smaller appliances, while larger appliances like refrigerators should remain plugged in but turned off to avoid overload when power returns.
  • Use Surge Protectors: For devices that cannot be unplugged, use surge protectors to help shield them from voltage spikes that can occur when power is restored.
