In addition, health risks from contaminated or spoiled food may increase. If you have limited heat for cooking, choose foods which cook quickly. Many foods can be skewered, grilled, or wrapped in foil and cooked in fireplace. If gas is cut off, but you still have electricity, use electric skillets, hot plates, or coffee makers to heat food. Devices using candle warmers such as fondue pots may be used if no other heat sources are available.

These may be used outside your home. Never use fuel-burning camp stoves or charcoal burners inside your home, even in a fireplace. Fumes from these stoves can be deadly. Some frozen foods require considerably more cooking time and heat then canned goods. Also, if power is off, it is best to leave the freezer door closed to keep food from thawing.
