The biggest Blackout in U.S. history occurred on August 14, 2003, leaving roughly 50 million people without power. Blackouts can happen anywhere, and to anyone, so being prepared is important.
BEFORE A BLACKOUT
To prepare for a blackout you should do the following:
To begin preparing, you should build an emergency kit and make a family communications plan.
Follow energy conservation measures to keep the use of electricity as low as possible, which can help power companies avoid imposing rolling blackouts.
Fill plastic containers with water and place them in the refrigerator and freezer if there’s room. Leave about an inch of space inside each one, because water expands as it freezes. This chilled or frozen water will help keep food cold during a temporary power outage, by displacing air that can warm up quickly with water or ice that keeps cold for several hours without additional refrigeration.
Be aware that most medication that requires refrigeration can be kept in a closed refrigerator for several hours without a problem. If unsure, check with your physician or pharmacist.
Keep your car tank at least half full because gas stations rely on electricity to power their pumps.
Know where the manual release lever of your electric garage door opener is located and how to operate it. Garage doors can be heavy, so know that you may need help to lift it.
Keep a key to your house with you if you regularly use the garage as the primary means of entering your home, in case the garage door will not open.
DURING A BLACKOUT
Use only flashlights for emergency lighting. NEVER use candles during a blackout or power outage due to extreme risk of fire.
Keep refrigerator and freezer doors closed to keep your food as fresh as possible. If you must eat food that was refrigerated or frozen, check it carefully for signs of spoilage. Turn off or disconnect appliances, equipment (like air conditioners) or electronics in use when the power went out. Power may return with momentary “surges” or “spikes” that can damage computers as well as motors in appliances like the air conditioner, refrigerator, washer or furnace.
Do not run a generator inside a home or garage.
Do not connect a generator to a home’s electrical system. If you use a generator, connect the equipment you want to run directly to the outlets on the generator.
Listen to local radio and to a battery- or generator-powered television for updated information.
Leave on one light so that you’ll know when your power returns.
Use a standard telephone handset, cellular phone, radio or pager if your phone requires electricity to work, as do cordless phones and answering machines. Use the phone for emergencies only. Listen to a portable radio for the latest information.
Do not call 9-1-1 for information—call only to report a life-threatening emergency. Use the phone for life-threatening emergencies only.
Take steps to remain cool if it is hot outside. In intense heat when the power may be off for a long time, consider going to a movie theater, shopping mall or “cooling shelter” that may be open in your community. If you remain at home, move to the lowest level of your home, since cool air falls. Wear lightweight, light-colored clothing. Drink plenty of water, even if you do not feel thirsty.
Put on layers of warm clothing if it is cold outside. Never burn charcoal for heating or cooking indoors. Never use your oven as a source of heat. If the power may be out for a prolonged period, plan to go to another location (the home of a relative or friend, or a public facility) that has heat to keep warm.
Provide plenty of fresh, cool water for your pets.
Eliminate unnecessary travel, especially by car. Traffic signals will stop working during an outage, creating traffic congestion.
Remember that equipment such as automated teller machines (ATMs) and elevators may not work during a power outage.
AFTER A BLACKOUT
Throw out unsafe food:
Throw away any food that has been exposed to temperatures 40° F (4° C) for 2 hours or more or that has an unusual odor, color or texture. When in doubt, throw it out!
Never taste food or rely on appearance or odor to determine its safety. Some foods may look and smell fine, but if they have been at room temperature too long, bacteria causing food-borne illnesses can start growing quickly. Some types of bacteria produce toxins that cannot be destroyed by cooking.
If food in the freezer is colder than 40° F and has ice crystals on it, you can refreeze it.
If you are not sure food is cold enough, take its temperature with the food thermometer. Throw out any foods (meat, poultry, fish, eggs and leftovers) that have been exposed to temperatures higher than 40° F (4° C) for 2 hours or more, and any food that has an unusual odor, color or texture, or feels warm to touch.
LISTEN TO LOCAL OFFICIALS
Learn about the emergency plans that have been established in your area by your state and local government. In any emergency, always listen to the instructions given by local emergency management officials.
PEOPLE WITH DISABILITIES AND OTHER ACCESS FUNCTIONAL NEEDS
Call your power company before rolling blackouts occur if you use a battery-operated wheelchair, life-support system or other power-dependent equipment. Many utility companies keep a list and map of the locations of power-dependent customers in case of an emergency. Ask them what alternatives are available in your area. Contact the customer service department of your local utility company(ies) to learn if this service is available in your community.
Have an extra battery if you use a motorized wheelchair or scooter. A car battery also can be used with a wheelchair but will not last as long as a wheelchair’s deep-cycle battery. If available, have a lightweight manual wheelchair for backup.
Have a talking or Braille clock or large-print timepiece with extra batteries if you are blind or have a visual disability.
Consider getting a small portable battery-operated television set if you are deaf or have a hearing loss. Emergency broadcasts may give information in American Sign Language (ASL) or open captioning.
USING A GENERATOR
Get advice from a licensed professional, such as an electrician if you are considering obtaining a generator. Make sure the generator is listed with Underwriter’s Laboratories or a similar organization. Some municipalities, Air Quality Districts, or states have “air quality permit” requirements. A licensed electrician will be able to give you more information on these matters.
Plan to always keep the generator outdoors—never operate it inside, including in the basement or garage. Do not hook up a generator directly to your home’s wiring. The safest thing to do is to connect the equipment you want to run directly to the outlets on the generator.
