Common Questions
What should I do when the power goes out?
First: check if the electrical outage is localized or area-wide (check your neighbors). Report the outage to your utility provider. Turn off major appliances. Use flashlights. Keep refrigerator doors closed. Run generators and grills outdoors only.
How long does food stay good in a fridge without power?
4 hours in a closed refrigerator at safe temperature (40 degrees F or below). Discard any perishable food (meat, dairy, eggs, leftovers) after 4 hours without power. Use a thermometer to verify temperatures when power returns.
How long does food stay good in a freezer without power?
48 hours in a full, closed freezer; 24 hours in a half-full freezer. Food that still contains ice crystals or is 40 degrees F or below can be refrozen. Discard anything that has warmed above 40 degrees F.
Can I use a generator indoors?
No. Never use a generator indoors, in a garage, or within 20 feet of any open window. Generators produce carbon monoxide (CO), which is invisible, odorless, and deadly. Install CO alarms on every level of your home. Place generators outdoors in open air facing away from the house.
How do I keep my pipes from freezing in a winter power outage?
Drain pipes or leave faucets dripping to relieve pressure. Open cabinet doors so any residual warm air reaches exposed pipes. If temperatures will stay below freezing for days without heat, shut off the main water valve and fully drain the system to prevent burst pipes.
What is the best backup power source for a home?
A whole-house standby generator (permanently installed, natural-gas or propane-fueled) is best for extended outages. Portable generators work for short outages. Solar battery systems provide silent backup for essential loads. Choose based on outage frequency and budget.
