Baking soda is an effective fire reduction method. However, flour and baking powder are very dangerous around flames. Flour is flammable and it can also conduct electricity.

You don’t have to put smoke detectors in every room. At a minimum, though, there should be one on every level of your home, one in every bedroom, and one in the hallways outside the bedrooms.
