All electronic or automatic garage doors have a bypass that allows you to open them manually. Make sure you know how to open your garage door by hand in the event of a power outage—or a lost remote.

Don't Play With Fire

If you choose to light up your darkness with candles instead of flashlights, place them on a solid, stable, noncombustible surface, and make sure to have a fire extinguisher handy. Never leave a burning candle unattended.

Have a Backup

In the event of a surge or outage, these handy devices will keep your electronics running until you are able to shut them down safely.

Suppress Those Surges

Install surge protectors (like this option from Amazon) to help suppress surges and voltage fluctuations, which will protect equipment from damage during power disturbances.

When in Doubt...

. . . throw it out. After a power outage, never rely merely on smell or appearance to determine if food is safe to eat. According to, food should be safe if the power has been out for no more than four hours. Discard any perishable food, such as meat, poultry, fish, eggs, and leftovers, that has been above 40 degrees F for more than two hours.

Consider a Generator

Many homeowners install generators to ensure continuous power availability. If you think you might want to run your house (or a portion of it) on a generator, take the time to do some planning first.

Protect Your Data Line
