{wiki=Rollover_(fire)}
Rollover, in the context of fire, refers to a phenomenon where unburned gases in a compartment ignite and produce a sudden, intense fire event. This typically occurs when hot gases and smoke accumulate at the top of a room or enclosed space. As these gases become heated and reach their ignition temperature, they can ignite simultaneously when a sufficient amount of oxygen is available, resulting in a rapid fire spread.
