Short title	Hot layer ignites immediately; cooler layer ignites only after air mixes back to fire.
Image title	Two qualitative timelines starting when a door opens and air enters. Top: a hot gas layer ignites immediately. Bottom: a cooler gas layer first goes through an air-fuel mixing period of no fixed length (shown with a break), the mixture reaches the fire source and only then ignites. A note states that no flame at the moment of opening does not mean the atmosphere is safe.
