Power Outage Kits

Be prepared for a power outage by keeping necessary items centrally located in your home. Take the time to ensure that everyone in your family is aware of the "kit." Periodically check your kit to see that batteries operate properly. The following is a list of items that are suggested to keep on hand:

  1. Flashlights for each family member

  2. Battery-operated radio and clock

  3. Extra batteries

  4. Containers of bottled water

  5. Canned, freeze-dried or dehydrated food, powdered milk, baby supplies for infants

  6. Non-electric can opener

  7. List of important phone numbers

  8. First-aid kit

  9. Know how to manually operate an electric garage door

Food Alerts

Do not refreeze melted ice cream, yogurt, or seafood, food that has thawed completely and been held above 40 degrees for two hours or longer, anything with custard fillings, or any foods with a questionable texture or odor. A general rule on food spoilage is: If in doubt, throw it out.

If you have any questions about the safety of defrosted foods, you can call the U.S. Department of Agriculture's toll-free "Meat and Poultry Line" at 1-800-535-4555 weekdays, 10 a.m. - 4 p.m.

Garage Doors

Electric garage doors may be opened by disengaging the drive mechanism. Methods used to do this vary from manufacturer to manufacturer. Please consult your operating instructions supplied by the manufacturer. They will tell you how to disengage the drive mechanism so that you can open the door manually. If you do not have a manufacturer's instruction book, call the company that installed the doors.

Water Pipes

Keep your pipes from freezing by shutting off the valve that allows water to come into your home. Then, open any drain valves and all faucets and let them run until the pipes are empty (it's helpful to identify these valves in advance). Next, flush all toilets and pour denatured alcohol into toilets and sinks to prevent water in the traps from freezing. Do NOT use automotive antifreeze in case there's trouble with your water system; you don't want the antifreeze to contaminate your drinking water. You may, however, use nontoxic antifreeze that's made for winterizing motor homes.

Turn off the furnace emergency switch. Then drain your furnace boiler by opening the valve at the bottom (this looks like a garden faucet). Also, open all radiator vents. Be sure the boiler is filled with water again before it is restarted.

The tank of your electric water heater will keep water warm for the first few days after an outage. However, it can freeze after prolonged cold and should be drained after three days of below freezing temperatures.

Medical Problems

Find out about local shelters ahead of time if you have a medical problem. If you are ill or frail, consider staying with relatives if the outage will be lengthy.

If a member of your household relies on electric equipment for a life-threatening medical condition, we suggest a back-up plan to provide the patient with alternative facility care in case of a prolonged outage.

If you have medication that requires refrigeration, check with your pharmacist for guidance on proper storage during an extended outage. You may want to keep a small cooler handy.

Pets

Smaller pets such as fish, birds and reptiles may be endangered. Since many of these animals are fragile, we recommend that you do not wait until an outage strikes to devise alternate arrangements.

Check with a reputable pet store to determine what steps you can take before and during an outage to ensure your pet's survival.

Appliances

Before a storm you might set your refrigerator and freezer to their coldest settings (remember to reset them afterwards). It's a good idea to place plastic containers filled with water in your freezer because ice helps maintain the cold during outages.

During a major outage try not to open the refrigerator or freezer doors any more than necessary. If the unit's door is unopened, food stays in a full refrigerator for up to 24 hours and in a freezer up to approximately 48 hours if it's well packed; approximately 24 hours if it's half packed. You might load up a cooler with ice and store food you'll need during the first day or so after an outage.

When an outage occurs, turn off most appliances to prevent an overload on the electrical system when he power is restored. You may choose to leave your refrigerator and freezer on.

Always Be Prepared

There are approximately 5,000 house fires every year in the United States...one out of eight of these fires is started by faulty wiring or by household appliances.

If you don't have a family fire drill plan, get one! If you need help putting a fire drill plan together, call your local Fire Department. They can help you find the quickest and best escape routes from your home. Having a fire drill plan in place, and practicing it, can save your family's lives.

Other things you can do to be prepared are:

Put a fire extinguisher on every floor, and make sure everyone in your home knows how to use it.

Install smoke detectors on every floor, making sure there is one outside your bedroom doors.

Test your smoke detectors every month! Smoke detectors don't work if the batteries are dead!

There are electric smoke detectors available now that are connected to your household electrical wiring. Since they are operated by electricity, there's no need to change batteries. It's still a good idea, though, to check them each month to make sure they're working properly.

How long can pipes go without power before freezing?

The rule of the thumb is that it takes roughly 6-hours for water in your pipe to freeze after left in an unheated area. Meaning if you lose power at your home and the weather is reaching below freezing point, you have approximately 6-hours until the pipes will begin to freeze.

Will pipes freeze in a house without heat?

However, according to research conducted by the Building Research Council at the University of Illinois, the temperature threshold for pipes to freeze without heat is 20 degrees F.

Will pipes freeze in empty house?

Physicsist's answer: no. If the pipe is completely empty, there will be no water to freeze. The water vapour in air will not be able to condense on it either, because your house's walls (and pipes) will be slightly warmer than the ambient temperature on a typical day.

What temperature should I keep my house so the pipes don't freeze?

Regardless of how long you will be traveling and away from home, keep your thermostat set at 68 degrees Fahrenheit or above. This will help to keep the pipes on the inside of the home from freezing and the ones under the home at a slightly higher temperature as well.
