Portable cooking appliances, such as toasters and electric griddles, can also be a source of fires. Never leave these portable appliances unsupervised, and make sure they are cool to the touch before storing them away. Toasters should be regularly cleaned of crumbs that might ignite if they build up inside the appliance. During the outdoor cooking season, barbecue grills left unattended on a wooden deck or near the exterior walls of a home can also be a source of fire.
