Your oven has a clean cycle for a reason, turns that and all the other disgusting shit you’ve probably been splattering all over the inside into much easier to deal with ash. Don’t worry about starting a fire in there either, the inside of the oven is supposed to get hot.
Edit: I should clarify what I mean by "don’t worry about starting a fire in there. Of all the places in your house, save for a fireplace if you have one, the oven is by far the best place for a fire to be. So if a fire does start in your oven during the clean cycle it’s fine, hell go watch it because it’s the closest thing you get to a fireplace in apartment life.
