Pregnant women and unborn babies are particularly at risk. A box of baking soda is a good emergency fire extinguisher. Use bricks to make a stand for a pot or to hold a grill in an open fireplace. Dutch ovens can be cooked in fires outside in the yard or in the fireplace. Charcoal briquets can be used with cast iron skillets, Dutch ovens, and other pots and pans, but such cooking must be done outside.
Most kerosene heaters get hot enough on top to cook food.
This could be a low cake pan, or empty tuna cans, or the trivet from your gas range. Large cans or pot lids also work. Keep an eye on the food as it is baking. You may have to flip biscuits so that they brown on top. Chafing dishes come in many different sizes and use small cans of jelled fuel for heat, some use candles or denatured alcohol burners.
