Short title	Oxygen-limited room accumulates fuel gas, a door opens and mixed gases ignite explosively.
Image title	Three room cross-sections in sequence. 1, closed: a small oxygen-starved fire under a deep layer of fuel-rich gas, door closed, limited oxygen. 2, opened: the door opens, fresh air flows in along the floor while hot gas leaves at the top of the opening. 3, ignited: the air-fuel mixture ignites, flame travels through the gas layer and a fireball is expelled through the opening.
