There are three important tips to remember during a blackout: Keep refrigerators and freezers closed to keep food from perishing. If the heat or cold is extreme, go to another place with power for warmth or cooling. Don’t forget to check up on your neighbors! Power outages and blackouts may not last very long, but in case they last for a day or two – be prepared. It’s always a good idea to have non-perishable food in the house along with water bottles for emergencies. Batteries and battery-powered equipment, like flashlights, will also be extremely useful during an electricity outage for light and other uses.
