Of course you shouldn’t do that, silly.

What I meant was if you are cooking on your stovetop using a pan and somehow don’t have a lid, fire blanket, fire extinguisher etc, you can just put it inside the oven. Flames and all. Just make sure you shut the door. It works best when the oven is not filled or in use

This stops the fire from spreading, and starves it of oxygen quickly. Another alternative method is to use another pot/pan that’s just big enough to cover the top of the burning pan.
