Yes. Cooking all day while you work is what this appliance was designed to do. These machines are all safety certified by the Nationally Recognized Testing Laboratories UL and ETL, so you don’t have to worry about them exploding or starting a house fire. For extra peace of mind, here are a few safety tips: 1 - Place it on a hard, flat surface at least a few inches away from the wall and other objects. 2 - Keep the top on, but not locked. 3 - Fill it between ⅔ and ¾ full. 4 - Keep it on low, especially if you’ll be out of the house all day.
