Power Outage

Electrical power can go out for any number of reasons. An unexpected power outage can have unforeseen consequences. Without electricity you may experience a shortage of food and clean water, as well as extreme temperatures. You should be prepared to manage without power for an extended period of time.

  • Rolling blackouts
    • Rolling blackouts, or temporary power shortages, may happen from time to time when power companies turn the power off in certain areas to curb usage.
    • Rolling blackouts occur during peak seasons and hours of energy consumption, usually in the summer, 4–7 p.m.
  • Summer blackouts
    • Extreme heat is usually the cause of summer blackouts.
  • Space weather
    • Space weather, sometimes called solar storms, can produce electromagnetic fields that cause extreme currents (power surges) in wires, disrupting power lines, and even causing widespread blackouts.

  • Verify and update official contact information in the Marine Corps Enterprise Mass Notification System (eMNS), and register all cell phones, home phone, email addresses, etc. in eMNS. 
  • Make a family emergency plan.
  • Back up computer files regularly.
  • Keep your car tank full because gas stations rely on electricity to power their pumps.
  • Keep a key to your house with you if you regularly use an electronic garage door opener to enter your home.
  • Know where the manual release lever of your electric garage door opener is located and how to operate it.
  • Build an emergency kit.
What to Do If There Is a Power Outage
  • Use flashlights rather than candles for light.
  • Turn off the electrical equipment you were using when the power went out.
  • Eliminate unnecessary travel.
  • Remember that ATMs and elevators may not work.
  • Drink and use bottled, boiled, or treated water.
  • Make sure your pets have plenty of fresh, cool water.
  • Try not to open the freezer or refrigerator often. A full freezer should keep food for 48 hours.
  • Pack dairy products, meat, fish, eggs, and other items that can quickly spoil in a cooler surrounded by ice to extend their usability.
  • Throw out any foods (meat, poultry, fish, eggs, and left­overs) that have been exposed to temperatures higher than 40° F (4° C) for two hours or more, and any food that has an unusual odor, color, or texture, or feels warm to touch.
  • If the power goes out in extreme heat:
    • Stay hydrated by drinking a glass of water every 15–20 minutes.
    • Wear light-colored, loose-fitting clothing.
    • Keep the air circulating by opening doors and windows.
    • Be aware of the possibility for a heat stroke.
  • If the power goes out in extreme cold: 
    • Wear several layers of warm clothing.
    • Keep moving to stay warm.
    • Be aware of the possibility for hypothermia, which hap­pens when one’s body temperature falls below 95˚F.


Set your own course through any hazard: stay informed, make a plan, build a kit. Live Ready Marine Corps.
