🔥 FLAMEOVER (ROLLOVER): A LIFE-THREATENING WARNING 🔥 Flameover—also commonly called rollover—is not just “cool fire behavior.” It is a critical warning sign that conditions inside a compartment are rapidly becoming deadly. Flameover occurs when unburned fire gases produced by incomplete combustion accumulate at the ceiling level, mix with oxygen, and then ignite, causing visible flames to roll or lick across the overhead—often before full flashover. 🚨 Key warning signs of flameover: • Flames

Fire rollover occurs when superheated, unburned gases rise and collect near the ceiling of an enclosed space. As these gases mix with oxygen and reach ignition temperature, they ignite suddenly, creating rolling flames across the upper layer of the room. This can happen even when materials on the floor have not yet caught fire. Flashover is a more extreme stage of fire development. It happens when heat from the fire raises the temperature of all exposed combustible surfaces in a room to their ig

New York State Police demonstrate their "Rollover Simulator" at today's Buckle Up in the Parks event, which demonstrates the importance of using seat belts in the event of a rollover accident. The rollover simulator is a compact pickup truck cab affixed to a two-axle trailer. It features an acceleration and braking control system to spin the cab, simulating a rollover crash. | New York State Department of Motor Vehicles
