BUFFALO, NY (WKBW) - It's call a "Flashover," and it poses a deadly threat to firefights working inside a burning building.
They happen when super-heated smoke suddenly bursts into flames, and learning the signs of a 'flashover' can save a fireman's life.
Members of some local fire departments received some training inside a flashover simulator. One firefight wore a camera inside the simulator as smoke and gas erupted into deadly, hot flames.
