Short title	Comparison of ventilation-triggered backdraft, premixed smoke explosion and radiative flashover.
Image title	Three columns. Backdraft: a fuel-rich gas layer builds up in a closed-down room, then air enters through an opening and ignition follows at the fire. Smoke explosion: a premixed smoke-air atmosphere already exists in a closed space and is ignited by a source. Flashover: the hot layer radiates down onto several combustible objects, which heat and ignite across the room. A note says a fireball alone does not identify the event.
