LOUISVILLE, Ky. (AP) -- Louisville Gas and Electric and Kentucky Utilities have some advice for Kentucky residents in this week's cold weather.
The utilities say while power outages usually don't require backup power sources, some people do use portable generators in emergencies, but they must be operated safely. Make sure the generator is the right size, and have a licensed electrician ensure it's properly installed and that the wires are isolated from the utilities' electric system. Portable generators must be operated outside and be properly vented. Never refuel the generator while it's operating.
Natural gas also requires precautions. Don't use a gas oven to heat your home as it can create deadly carbon monoxide gas. Be aware of the warning smell, sound and sight of leaking gas, and report any leaks.
Ice on tree branches can cause downed power lines. If you see a downed wire, stay away and call the utility company.
