When dealing with an oven fire, what is the initial action to take?

The initial action to take when dealing with an oven fire is to close the oven door. This method is effective because it helps to suffocate the fire by cutting off its oxygen supply. Ovens are usually designed to contain flames, and by keeping the door closed, you prevent the fire from spreading and potentially escalating into a larger hazard.

Using water on the fire, which is another common instinct, can actually exacerbate the situation in certain cases, especially if the fire involves grease or oil. Removing the source from the oven can be dangerous as well, as it may expose one to flames or allow the fire to spread. Calling for assistance is important if the situation worsens, but immediate action to contain the fire is crucial, making closing the oven door the safest first response.
