(Meredith) -- Although you probably only put food in the oven, there are a few things you might want to avoid next time you cook.
1) Unprotected food and food debris, like greasy or sugary foods. Those can easily start a fire in your oven.
2) Plastic. Even if plastic doesn't melt, it can still leech harmful chemicals into your food as it heats up.
3) Glassware. Only use glassware that is designed for oven use, is full of food and has no cracks or chips.
4) Paper products. Paper towels, plates and bowls are not designed to be heatproof and can burn.
5) Wet or damp towels, potholders, or oven mitts: Any water can turn to steam and can result in burns.
