The moment you become aware of a power outage you should immediately try and find out how much of the surrounding area has been affected. This is mainly to determine if it is affecting just your house, because if it is you will need to be the one to take action to get the issue fixed.
Some tips for staying safe and warm during a power outage are:
->Wear extra layers of warm clothes
->Bring out the extra blankets
->Use your fireplace (if you have one)
->Close off all the doors to the room you’re in to keep the warm air in and conserve body heat.
