When the lights go out, it's important to follow a few safety tips for when the power comes back on. During a power outage, turn off electrical appliances and any small electric devices.
The reason for a power failure can range from damage to a power line, a problem at a power station, or the overloading of electricity mains. Major appliances will need to be turned off, including your air conditioner, heater, or washer.
If the power's out and you have to leave home, that's when it's really important to make sure those items are off. Lt. Greg Loyd with the Sherman Fire Department says, "You don't know how that power will come back up."
"Wait for power to come back up and then turn appliances back on," he said.
Also, the Centers for Disease Control recommends that if an outage lasts longer than two hours, the food in your refrigerator or freezer could start to go bad.
