The radiated heat from this layer heats the surfaces of the directly exposed combustible materials in the room, causing them to give off flammable gases, via pyrolysis. This is because the temperature of most workplaces will not be above the lowest combustible flash point (37.8 C), which means that combustibles wont start to form vapours in a normal working environment. If not interrupted, this cycle - known as thermal radiation feedback - drives up the temperature and creates an Learning to recognize when flashover conditions exist can save your life.
