More than 4 million customers in Texas were at the dark this week as ice and snow hockey the state.
Almost 500,000 customers were without power Thursday morning.
Here are safety tips to Remember:
In Houston a girl and an 8-year-old woman died from carbon monoxide poisoning following a vehicle was left running at a garage to get warmth, authorities said, based on ABC Houston channel KTRK.
Never use a gas stovetop or oven to heat your house, and just utilize generators, camp stoves or charcoal grills whenever you're outside and 20 feet from windows, FEMA officials said.
Keep toaster and toaster closed throughout the power outage, rather using food which does not need heating or coolers with ice hockey. The refrigerator will keep food cold for approximately four hours as a freezer will keep the temperature for approximately 48 hours, officials said.
FEMA officials advocate storing a thermometer in the refrigerator and freezer; after electricity is restored, throw food out when the temperature is 40 degrees or greater.
In case the electricity is out for at least 1 day, throw any drugs which needs to be trashed, unless the label states differently, FEMA officials said.
While attempting to remain warm, officials at Bexar County, Texas, advocate closing the blinds to maintain some warmth, shutting off rooms to prevent wasting warmth and stuffing towels or tags in cracks under doors.
