Everyone has to heat their homes in the winter, doing it safely can mean the difference in surviving the winter or dying in a house fire because of poor heating safety practices. There are plenty of tips in the picture, but to these I would like to add that if you running you close dryer and decide to leave or go to bed turn the dryer off and also make sure to clean the lint filter and the exterior exhaust vent to insure the air can pass freely through the dryer and not cause a fire.
