Power outages can put you and your home at risk. Here's what you need to know to stay safe.
Heat waves, freezing temperatures, problems with the electrical grid, natural disasters, or even just a downed tree can all lead to an interruption in your electricity services. It’s important to know how to deal without power to keep yourself, your home, and your pets safe. Here are some tips for what to do when your power goes out, no matter what the cause.
How to stay warm
What to do when the power goes out? Well, the most important thing, if it’s cold outside, is to save what heat you have in your home. Cover windows and doors with blankets, or tape plastic over them, to keep out drafts and to slow down the cooling process inside of your home.
One room is much easier to keep warm than multiple rooms, so next, choose a “warming room.” This is a room that you will spend your time in until the power comes back on. The best room is the one that has the least windows and that’s small. Have everyone in your household bunker down in this room, including pets. Body heat will help keep the room warm if you keep the door closed. Make sure to bundle up with blankets and hot water bottles, too.
If you have a camping tent, setting it up as your warming room in the middle of the living area or in a bedroom is a great idea, too. Tents are designed to trap body heat, and they’re small, so they don’t take long to heat up.
Whatever you do, do not use gas ovens, grills, or heaters to keep warm. These can cause a buildup of noxious gases in your home that can be deadly.
Once everything gets back to normal, here are 15 tricks to keep your home warm while saving on heating.
How to stay cool
Staying cool during hot weather is just as important as staying warm during cold weather. Here are some tips for what to do when your power goes out during the summer:
Make sure that you stay hydrated. Your body needs water to cool itself down.
Cover windows with curtains or blankets to keep out the hot sun.
Open windows that aren’t facing the sun to let in a breeze.
Wear a wet bandanna around your neck or head and fan it with your hands, a magazine, or a battery-powered fan to cool yourself.
Take a cool shower or bath. Add ice to your bath if the water coming from the cold tap is warm.
Cook outside on a grill instead of using your gas stove to prevent adding more heat to the inside of your home.
Not cool enough? These tips will keep your home cool without AC.
Keep food fresh and safe
When your electricity goes out, the food inside of your fridge and freezer are at risk of becoming too warm. When food gets too warm, it can grow dangerous bacteria. According to the FDA, food needs to remain at 40 degrees or below to prevent spoilage. To ensure food stays chilled, there are a few things you can do.
Bob Gravani, Institute of Food Technologists (IFT) member expert and professor of food science at Cornell University shares these tips of what to do when your power goes out:
Make sure you have an appliance thermometer in your refrigerator and freezer. Your refrigerator should be at or below 40 degrees Fahrenheit (4.44 degree Celsius), and your freezer should be at or below 0 degrees Fahrenheit (-17.78 degree Celsius).
Have some coolers on hand to store refrigerated foods. Freeze containers of water (such as empty gallon jugs), as well as ice cubes and gel packs, ahead of time for use in coolers to keep food as cold as possible if the power goes out. If you can, plan ahead and find out where you can buy dry ice and block ice.
Keep the doors to your refrigerator and freezer closed as much as possible. Your refrigerator should maintain its cold temperature for about four hours without power. A full freezer will hold its temperature for about 48 hours, but only 24 hours if it is half full.
When in doubt, throw it out. If at any point food is above 40 degrees Fahrenheit (4.44 degree Celsius) for two hours or more, throw it away. Never taste food to determine if it’s safe or depend on appearance or odor. Food in the freezer that still has ice crystals can be refrozen or cooked, but if you’re unsure, it’s better to toss it out. Eating food not kept at the proper temperature may cause illness even when thoroughly cooked.
Keep a three-day supply of nonperishable food that doesn’t require refrigeration or cooking such as canned goods and boxed milk. And don’t forget to stock up on bottled water.
Making sure your water is safe is important, too. When the power goes out for you, it might also be out for the municipal water treatment center, so you may not have water for long. You can stock up on water by filling up your bathtub.
Power outages at water treatment plants can also mean that your water may become unsafe for both you and your pets. “Even though the water coming from the tap looks clean, it could be unsafe to drink. Check with the local authorities to see if there is a boil alert in effect,” says Diane Vukovic, author of Disaster Preparedness for Women. Vukovic advises bringing the water to a full rolling boil for one minute or, if you live at an elevation of 6,500 feet or more, three minutes.
If your home uses well water, you likely won’t have water until the power comes back on. The best way to get your water back is to hook your well pump up to a gas-powered generator. You can often rent these types of generators at local equipment rental service providers. Installing a permanent backup generator is a good idea to keep water flowing during outages in the future. You may also want to research if your well system can support the addition of a manual pump that can be used without electricity.
Save your pipes
Your home can be susceptible without electricity, too. During cold weather, pipes can easily freeze and burst if the home isn’t heated. To prevent pipes from freezing, turn on all of the cold water faucets in the house so that they are dripping. Just this little bit of water flowing can prevent pipes from freezing solid.
“However, this isn’t a good solution when water outages are also a concern,” notes Vukovic. “You’ll need to completely shut off your water at the main and drain water in the pipes (collect it in clean buckets and pots so you can use it later). Also, drain your water heater so it doesn’t crack. To protect your drainage system, you can put antifreeze in the drain traps below sinks, toilets, and washing machines.”
Pipes already frozen? Don’t panic. Here are 10 tricks to unfreeze them.
Protect your electronics
Another way to protect your home is to unplug everything, even your major appliances. When the power returns, there may be a power surge, which can damage anything still plugged in.
Now that you know what to do when the power goes out, do you know what a Chinook wind or a derecho is? These are the weather terms you need to know.
