Unattended cooking causes the majority of fires in the kitchen.
Do not try to force the door open, turn unit off and call the Fire Department. Avoid putting any metallic materials in the microwave oven which may cause sparks and eventually damage the microwave. Remember never use water on a grease fire, water will spread the fire and make it worse. Turn off the heat, and put a lid on the pan to extinguish the fire. Kitchen Safety Keep pot handles turned in on the stove top to avoid accidentally knocking the pot off, causing serious burns.
