Being without electricity is more than an inconvenience: not having access to power can impact your ability to keep food and medications cold, see potential danger around you, maintain a comfortable temperature and stay connected to safety services.
Here's what you can do to stay safe if you're without power:
The basics
It's crucial to ensure electric appliances are disconnected to avoid any harm or damage from power surges, according to the Federal Emergency Management Agency.
FEMA also recommends keeping freezers and refrigerators closed to help maintain cooler temperatures for food preservation.
For good measure, turn off the main power breaker in your house and do not use any devices that are wet.
Watch out for carbon monoxide
Generators should only be used outdoors and placed more than 20 feet away from doors and windows, even if they are closed.
The devices emit carbon monoxide, which is a poisonous gas that can be lethal.
"(Carbon monoxide) is an odorless, colorless gas that kills without warning. It claims the lives of hundreds of people every year and makes thousands more ill," the US Centers for Disease Control and Prevention says.
The CDC also recommends ensuring battery-operated carbon monoxide detectors are placed near sleeping areas.
Discard flooded and too-warm food
Food that has been comprised by floodwater should not be consumed and should be thrown away, officials advise.
Refrigerated food that reaches at least 40 degrees Fahrenheit should be discarded, FEMA says
If you have medications that require refrigeration, find out how long they can be without it before their safety expires.
Use flashlights instead of candles
Avoid using candles during a blackout if possible. If you must use them, keep them away from anything that could catch fire and do not leave them unattended, the CDC says. Ensure a fire extinguisher is available and those around you know how to use it.
Avoid floodwaters as much as possible
Although it can be unavoidable when dangerous flooding is happening, stay out of floodwaters as much as possible.
Floodwaters can lead to the risk of drowning from the intensity of flow and winds. They can hide dangerous downed power lines and can also be chemically harmful because they contain germs, dangerous substances, human and livestock waste, the CDC says.
Check on your neighbors and loved ones
When it's safe, reach out to people around you to make sure they are doing well.
Those who have medical equipment that require power, like respirators, should be taken to locations with generators or a friend's or neighbor's home that hasn't been impacted.
And remember: The elderly and young children are especially vulnerable to extreme weather.
Protect your pets
Do not leave your pets behind if you evacuate during a power outage and never tie them outdoors during extreme weather events. "If you leave your pets behind, they may be lost, injured -- or worse," the CDC says.
Take the proactive step to contact your local emergency management office to learn about whether they have opened shelters to accommodate pets. To find a shelter near you, check out the Humane Society website. Be mindful that diseases can spread among pets and humans during extreme weather events.
Conserve power when possible
Power can be rationed by turning off and unplugging nonessential lights and appliances. Don't use large appliances like ovens or washing machines if you can avoid it.
Thermostats should be set to 68 degrees because heightened demand could trigger more blackouts -- or extend them.
