When should you keep the oven door closed during a fire?

Keeping the oven door closed during a fire is crucial for preventing the fire from growing larger. When a fire occurs in an oven, opening the door allows oxygen to feed the flames, which can intensify the fire and make it more difficult to control. By keeping the door closed, you effectively limit the airflow and can help snuff out the flames or at least prevent them from spreading. This practice is essential in kitchen safety and fire management, as it buys time while you seek help or try to extinguish the fire safely, preferably using an appropriate fire extinguisher.

The other options do not address the critical aspect of fire dynamics. For instance, keeping the door closed for reasons like preventing smoke from escaping does not address the immediate risk of a fire spreading. Similarly, if the oven is in use for cooking, that may not necessarily relate to the need to keep the door closed during a fire. Keeping food warm is also not a relevant consideration when dealing with a fire emergency.
