Power Outages: What to do During a Blackout

(Much of the information on this page is adapted from information provided by the American Red Cross and the Federal Alliance for Safe Homes)

DURING A BLACKOUT: THE BASICS

If someone in the home is on life-support or otherwise electric dependent due to a disability, immediately notify your Utility and your local Police Department.

For everyone else:

  • Call your utility to determine area repair schedules.
  • Listen to your battery-powered radio or television for updated information, and for any directions from public safety officials.
    • Remember: A battery-powered radio is a key part of your Emergency Supply Kit.
  • Use only a battery powered light, such as a flashlight, for emergency lighting! Due to the extreme risk of fire, DO NOT use candles during a power outage.
  • Avoid elevators.
  • Turn off or unplug lights and appliances to prevent a circuit overload when the power returns. Leave one light on to let you know when power has been restored.
  • Protect yourself from carbon monoxide poisoning:
    • Do not operate generators indoors.
    • Do not use charcoal to cook indoors.
    • Do not use your gas oven to heat your home.
    • All of these activities can cause a deadly buildup of carbon monoxide gas. Use space heaters with proper ventilation.
  • Keep your refrigerator and freezer doors closed as much as possible to avoid food spoilage.
  • Be sure to check on neighbors, especially the ill, those with electric-dependent medical needs and the elderly.
  • If it is cold outside:
    • Turn on faucets slightly to prevent pipes from freezing. Running water will not freeze as quickly.
    • Put on layers of warm clothing.
    • NEVER use your oven as a source of heat!
    • If power may be out for a prolonged duration, plan to go to another location that has heat to keep warm.
  • During a heat wave:
    • Watch for heat-related illnesses, especially in children who may not be able to verbalize how they feel.
    • Drink plenty of water, even if you do not feel thirsty.
    • Provide plenty of fresh, cool water for your pets.

FOOD SAFETY

Refer to "Help! The Power is Out!" (as PDF or text; also available in Spanish) available from the American Red Cross. This two-page flyer provides information on food safety and storage during power outages.

"Help! The Power is Out!" also contains a useful chart to help you decide whether to keep or discard foods after a blackout, depending on the type of food, temperature and duration of the outage.

Here are a few food safety tips:

  • Always remember: Food that has not been refrigerated can cause severe health problems.
  • Items in a full freezer will stay frozen for about two days with the door kept closed, and about one day in a half-full freezer.
    • If there is space in your refrigerator or freezer, consider filling plastic containers with water (remember to leave half an inch of space inside each container, because water expands as it freezes).
    • These containers of chilled or frozen water will help keep food cold by displacing air that can warm up quickly.
  • Refrigerated foods can keep for up to four hours during a blackout.
  • Discard any perishable refrigerated foods that have been above 40 degrees F for more than two hours.
  • Discard any food with an unusual odor, color or texture. Remember: "When in doubt, throw it out."

GENERATOR SAFETY

Refer to "Fact Sheet: Using a Generator When Disaster Strikes" (as PDF or text; also available in Spanish) available from the American Red Cross.

Here are a few generator safety tips:

  • Before obtaining a generator, get advice from a licensed professional such as an electrician.
  • Learn about air quality permit requirements that may exist in your area.
  • Due to the extreme dangers of carbon monoxide poisoning, always keep the generator outdoors. Never operate it inside, including in the basement or garage.
  • NEVER connect a generator to a home's electrical system unless you have an approved power transfer switch installed by a qualified electrician!
    • Instead, connect the equipment you want to power directly to the outlets on the generator.
