RELATED: Wind Chill Advisory issued for Fredericksburg (Should schools adjust their schedules?)
The Red Cross offers the following suggestions for dealing with the extreme cold temperatures headed toward Fredericksburg beginning tonight.
Protecting against frozen pipes
Before the onset of cold weather, prevent freezing of these water supply lines and pipes by following these recommendations:
Drain water from swimming pool and water sprinkler supply lines following manufacturer’s or installer’s directions. Do not put antifreeze in these lines unless directed. Antifreeze is environmentally harmful, and is dangerous to humans, pets, wildlife, and landscaping.
Remove, drain, and store hoses used outdoors. Close inside valves supplying outdoor hose bibs. Open the outside hose bibs to allow water to drain. Keep the outside valve open so that any water remaining in the pipe can expand without causing the pipe to break.
Check around the home for other areas where water supply lines are located in unheated areas. Look in the basement, crawl space, attic, garage, and under kitchen and bathroom cabinets. Both hot and cold water pipes in these areas should be insulated.
Consider installing specific products made to insulate water pipes like a “pipe sleeve” or installing UL-listed “heat tape,” “heat cable,” or similar materials on exposed water pipes. Newspaper can provide some degree of insulation and protection to exposed pipes – even ¼” of newspaper can provide significant protection in areas that usually do not have frequent or prolonged temperatures below freezing.
During Cold Weather, Take Preventative Action
Keep garage doors closed if there are water supply lines in the garage.
Open kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing. Be sure to move any harmful cleaners and household chemicals up out of the reach of children.
When the weather is very cold outside, let the cold water drip from the faucet served by exposed pipes. Running water through the pipe – even at a trickle – helps prevent pipes from freezing.
Keep the thermostat set to the same temperature both during the day and at night. By temporarily suspending the use of lower nighttime temperatures, you may incur a higher heating bill, but you can prevent a much more costly repair job if pipes freeze and burst.
If you will be going away during cold weather, leave the heat on in your home, set to a temperature no lower than 55° F.
To Thaw Frozen Pipes
If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Likely places for frozen pipes include against exterior walls or where your water service enters your home through the foundation.
Keep the faucet open. As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt ice in the pipe.
Apply heat to the section of pipe using an electric heating pad wrapped around the pipe, an electric hair dryer, a portable space heater (kept away from flammable materials), or by wrapping pipes with towels soaked in hot water. Do not use a blowtorch, kerosene or propane heater, charcoal stove, or other open flame device.
Apply heat until full water pressure is restored. If you are unable to locate the frozen area, if the frozen area is not accessible, or if you can not thaw the pipe, call a licensed plumber.
Check all other faucets in your home to find out if you have additional frozen pipes. If one pipe freezes, others may freeze, too.
Protecting your home and staying safe
Never use a stove or oven to heat your home.
If you are using a space heater, place it on a level, hard surface and keep anything flammable at least three feet away – things such as paper, clothing, bedding, curtains or rugs. Turn off space heaters and make sure fireplace embers are out before leaving the room or going to bed.
If you are using a fireplace, use a glass or metal fire screen large enough to catch sparks and rolling logs.
Use generators correctly – never operate a generator inside the home, including in the basement or garage.
Don’t hook a generator up to the home’s wiring. The safest thing to do is to connect the equipment you want to power directly to the outlets on the generator.
To stay safe during this winter storm the Red Cross recommends taking these steps
Wear layers of lightweight clothing to stay warm. Gloves and a hat will help prevent losing body heat.
After the storm, be extremely careful if you have to shovel snow. It is physically strenuous work, so take frequent breaks and stay hydrated.
Seek medical attention immediately if you have symptoms of hypothermia, including confusion, dizziness, exhaustion and severe shivering.
Watch for symptoms of frostbite, including numbness, flushed gray, white, blue or yellow skin discoloration, numbness, or waxy feeling skin.
Don’t forget your pets – bring them indoors. If they can’t come inside, make sure they have enough shelter to keep them warm and that they can get to unfrozen water.
Avoid frozen pipes – run water, even at a trickle, to help prevent them from freezing. Open the kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing. Be sure to move any harmful cleaners and household chemicals out of the reach of children. Keep the garage doors closed if there are water lines in the garage.
Keep the thermostat at the same temperature day and night. Your heating bill may be a little higher, but you could avoid a more costly repair job if your pipes freeze and burst.

This storm is already affecting millions of people and could result in the cancellation of Red Cross blood drives in those areas impacted by the weather. Despite the storm, hospital patients across the country will still need blood. If you are in a region unaffected by the storm, please consider making an appointment to donate blood or platelets.
Appointments can be online at redcrossblood.org or by calling 800/RED CROSS.
To give blood, someone must be at least 17 years of age, meet weight and height requirements and be in general good health. Donors should bring their Red Cross blood donor card or other form of positive ID with them. Some states allow 16-year-olds to give with parental consent.
